2 Solution Deployment Guide for IBM Tivoli Composite Application Manager for WebSphere

1.1 Services solution overview

This IBM Redbook provides a comprehensive guide to developing and deployinga services solution offering based on ITCAM for WebSphere. The solution is

targeted for small and mid-market businesses (SMB). Because many of thesebusinesses do not have IT staffs, they rely on trusted advisors like you. Deliveringcomplete and working solutions from the start in a minimal amount of time canhelp you establish long and prosperous relationships with these companies.

This services solution guide is developed specifically for Business Partners. It isdesigned to help you reduce the time and investment that are necessary beforeyou can begin selling and implementing solutions.

Resellers face certain challenges in trying to exploit opportunities. Identifying andassembling all of the relevant pieces that make up a meaningful solutionindividuallyhardware, software, networking installation, and configurationcanbe time-consuming and cumbersome tasks and might not be fully chargeable tothe customer. Solutions can be complex, and many demand high skill levels insales, service, and support.

The additional value-add for you consists of a set of offering-specific scenarios,service offerings, documentation, and templates that enable you to provide ahigh level of services and, therefore, increase the profitability of a solution sale. Atypical SMB relies on value-add resellers or consultants to provide a ready-to-go,affordable, customized Web-based business solution to solve immediatebusiness problems.

Before we proceed into the offering itself, we spend some time defining ITCAMfor WebSphere.

1.2 ITCAM for WebSphereconceptsITCAM for WebSphere is an application management tool that helps maintain theavailability and performance of on demand applications. It helps you quicklypinpoint, in real time, the source of bottlenecks in application code, serverresources, and external system dependencies. This product also providesdetailed reports that you can use to enhance the performance of yourapplications. ITCAM for WebSphere provides in-depth WebSphere-basedapplication performance analysis and tracing facilities.

ITCAM for WebSphere enables multiple levels of analysis in order to achieve acomplete view of the application, depending on the need. From theproduction-level monitoring through detailed heap and method debugging, it digs


15/136

Chapter 1. IBM Tivoli Composite Application Manager for WebSphere solution offering 3

into SQL performance analysis without the need for database monitors. It canprovide SQL information and calls that were made through Java DatabaseConnectivity (JDBC). ITCAM for WebSphere provides a composite statuscorrelation for transactions that use CICS or IMS as the back-end system.

ITCAM for WebSphere V6.0 evolved from WebSphere Studio Application Monitorand OMEGAMON XE for WebSphere. ITCAM for WebSphere observes andreports on the health of J2EE-based applications. It tracks the progress ofapplications as they traverse through J2EE application servers, middlewareadapters and transports, and database calls, and on to back-end systems suchas CICS or IMS to extract business data or to invoke mainframe businessprocesses. The tracking of applications produces request traces, where theevents in a requests life are recorded and stored in a monitoring repositorydatabase. ITCAM for WebSphere captures the CPU and the elapsed internal

times when events are called and when they are exited, measuring as far downas the CPU times consumed and the elapsed internal times charged to individualmethods in J2EE classes. The methods or events taking the most time aremarked as an applications parts that deserve attention for runtime improvementstudies and code optimizations.

ITCAM for WebSphere does not need modification of any application code. JavaVirtual Machine Tool Interface (JVMTI) interfaces and primitives, along withWebSphere Performance Management Interface (PMI) and z/OS System

Measurement Facility (SMF) 120 records, are ITCAM for WebSpheres principaldata sources. The monitoring data is collected and analyzed to offer a wealth ofinformation about the health of J2EE applications and their servers.

Many system-level performance metrics are collected and reported about J2EEapplication servers. The status of the servers and their resources (particularly atvital checkpoints such as CPU utilization), memory usage, and the status ofinternal components such as database connection pools, JVM thread pools,EJB usage, and request processing statistics can be very useful and important

for locating real-time problems with J2EE applications. ITCAM for WebSpherebrings attention to these critical indicators with real-time, graphical displays oftheir values and their trends over time.

1.2.1 Components

ITCAM for WebSphere is a distributed performance monitoring application forapplication servers. Its components are connected through TCP/IPcommunication. The central component of ITCAM for WebSphere, the managing

server, is its heart and brain. It collects and displays various performanceinformation from application servers. The application servers run a component ofITCAM for WebSphere called the data collector(DC), which is a collecting agent


16/136


that runs in the application server and sends monitoring information to themanagement server. These data collectors operate independent of each other.

Figure 1-1 shows the overall architecture of ITCAM for WebSphere.

Figure 1-1 ITCAM for WebSphere architecture

ITCAM for WebSphere has the following components:

The managing serverActs as the central component that manages andadministers the data collectors. It stores that data in a relational databaserepository. A Web-based application is provided to show the monitoringresults; this interface is also called the visualization engine. We discuss themanaging server in The managing server on page 5.

Data collectors run on the application servers that are being monitored. Theycollect performance information for the managing server. These datacollectors operate independent of each other. They are discussed inWebSphere data collector on page 6.

Tivoli Enterprise Monitoring Agentcollects information that shows the statusof the WebSphere server and sends this information to the Tivoli EnterpriseMonitoring Server for display via the Tivoli Enterprise Portal. Tivoli Enterprise

Monitoring Agent is installed on the individual machines where the datacollector resides.

The managing server

ITCAM for WebSphere managing server (MS) controls and coordinates datacollectors for J2EE, CICS or IMS servers that run applications.

The managing server consists of the following software:

The X-Windows Virtual Frame Buffer (Xvfb) graphics package

Managing server database, DB2 UDB, or Oracle (on Sun Solaris) forstoring data relationally

J2EE server to run the ITCAM for WebSphere graphical console application

An optional Apache Web server, such as IBM HTTP Server

ITCAM for WebSphere managing server overseer components, which are aset of Java-based components

The ITCAM for WebSphere overseer components are the controlling logic for themanaging server:

The kernels control the managing server. There are always two copies of thekernels running on an ITCAM for WebSphere managing server for

redundancy and failover. The kernels register components as they join themanaging server, periodically renew connections and registrations withcomponents and data collectors, and collect servers and componentavailability information.

Thepublishing servers receive application and system event data from thedata collectors, gather and compute request-level information aboutperformance metrics such as response times, and implement the trapmonitoring and alerts features.

The archive agents receive monitoring data from the publishing servers, andstore the monitoring data in ITCAM for WebSpheres repository.

Theglobal publishing servercollects information from the publishing servers,and correlates all parts and pieces of multi-server requests, like requests fromJ2EE servers to execute CICS or IMS programs.

The message dispatcheris a conduit for messages from ITCAM forWebSphere using e-mail and SNMP facilities.

Thepolling agents collect data from Web Servers for Apache 2.0 and above.

The visualization engine is a Web-based GUI with access to graphics, ITCAMfor WebSphere performance reports, real-time views of different slices ofmonitoring data, and access to ITCAM for WebSphere internal commands as


18/136


well as event-driven functions. The visualization engine runs on a J2EEserver, such as WebSphere Application Server.

Figure 1-2 shows the conceptual relationship between the components.

Figure 1-2 Kernel components

When it reaches the managing server, monitoring data is prepared for real-timedisplays within the monitoring console and is inserted into the ITCAM forWebSphere data repository. These are very resource-intensive operations;moving them to a standalone distributed server (or servers) isolates them fromother enterprise activities, thus reducing ITCAM for WebSpheres systemresource footprint in the monitored systems. This design also helps keep ITCAMfor WebSpheres processing overhead at levels low enough for 24x7 productionsystem monitoring.

Data from the distributed data collectors is collected by the publishing server andthen stored in the OCTIGATE database by the archive agent. The VisualizationEngine reads the database in order to present data through the Web console,while snapshot information such as lock analysis and in-flight transaction areretrieved directly from the data collectors.

WebSphere data collectorData collectors run inside the application servers. They use native system

services, and they are tailored for the particular environments where theyexecute. The data collectors for z/OS systems are written to take advantage ofservices on z/OS, such as MVS Cross-Memory Services and address spacefencing, which are not available on distributed systems.

Data collectors have two agents:

Command agent

The command agent collects requests from other components for informationabout EJB invocations, database connection pools, thread pools, stack

traces, memory analyses, and heap dumps. Event agent

The event agent provides data to the publish servers according to pollingfrequencies. This data includes system initialization data, applicationrequest-level data, and application method-level data.

Collectively, these agents and other data collector routines unleash the probes,package the monitoring data into Java formats for the managing server, and

deliver the data to the managing server.

The data collectors send the probes into the application servers to analyze theapplications performance. The probes collect monitoring data and feed it totransport routines that in turn route the data to the managing server. Themanaging server processes this data for appropriate display in the ITCAM forWebSphere console and for storage in the OCTIGATE repository. This relievesthe processing burden of ITCAM for WebSphere from the application servers asmuch as possible. The data collectors and probes are not designed to analyze or

interpret data, but to collect it and route it as quickly as possible to the managingserver where the analysis is performed.

The data sources employed by ITCAM for WebSphere are:

JVMTI garbage collection data, method trace, stack trace, CPU time, andheap dump

JMX system resources

SMF system resources (z/OS only)

PMI system resources

OS services SCC, platform CPU, and its environment

Byte Code Modification (BCM) instrumentation of some classes

The data collector in a J2EE server runs as a custom service called am.Figure 1-3 on page 8 shows the conceptual data collector structure.

2.3 Services engagement overview

You routinely rely on your skills and previous experience as a guide, but there arealways issues that require some educated guesswork. The goal of this section isto help you minimize the guesswork involved in planning and implementing asolution by providing a framework and time estimates for the major tasks.

A typical services engagement consists of:

Build an executive assessment (see 2.3.1, Executive Assessment onpage 17)

Set up a demonstration system or proof of technology (see 2.3.2,Demonstration system setup on page 18)

Analyze solution tasks (2.3.3, Analyze solution tasks on page 19)

Create a contract or statement of work (see 2.3.4, Creating a contract onpage 20)

The representative tasks and the time involved for custom solution execution are

included in the following section. Each customer has a unique set of needs, so theactual set of tasks to accomplish and the time involved might vary. However, this

list should help you understand implementation details, size the solution moreaccurately for the customer, and ensure a profitable engagement for yourself.

Note:Chapter 5, Complementary solutions for ITCAM for WebSphereengagement on page 105 offers details about additional services opportunities.


29/136


It is important to work with your customers to understand their expectations. Afteryou have gathered this data, document the tasks, deliverables, and associatedcosts in astatement of work. The statement of work acts as your contractualagreement with the customer for the duration of the project; therefore, a detailedand well-defined statement of work is advantageous both to you and your

customer.

A good overall understanding of the solution scope is a crucial prerequisite tosuccessfully selling, developing, and implementing it. As a solution provider, youmust understand what is involved in developing such a solution before you candiscuss it with your customer and size it for a cost estimate.

2.3.1 Executive Assessment

TheExecutive Assessmentis a billable service that you can offer to yourprospective clients. It offers a process designed to help you evaluate thebusiness needs of a company that is planning to deploy a solution for Web-basedbusiness. It was created for IBM Business Partners to help you close a higherratio of opportunities. It has been field-tested in markets all over North Americaand Europe and has received enthusiastic feedback.

The benefits of using the Executive Assessment in your sales process include:

Earning additional service fees More effectively qualifying prospective clients Shortening the sales cycle Streamlining the development process Closing a much higher ratio of potential engagements

This toolset helps you ask the right people the right questions so that you get theinformation you need to propose the appropriate solution. This assessment thenhelps you create a compelling business case that will persuade your prospect tobuy the required hardware, software, and services from you in the shortestpossible time.

The complete Executive Assessment process should take approximately 10 to 16hours. Table 2-1 shows the task breakdown.

This is a business-case assessment, not a technical assessment, so youraudience should be business owners, line-of-business executives, marketing andsales managers, and finally, the IT manager. The business owner orline-of-business executive is likely to be the decision maker.

For their initial investment, your clients get:

A business assessment prepared by a professional (you)

A competitive analysis

A prototype solution for their review

A strategic and tactical proposal for justifying and implementing their solutionfor Web-based business

Over the course of the Executive Assessment, you determine who will beinvolved in the project, what they want to accomplish, when they plan to deploy,where the Web plays a mission-critical role in their business, and how the projectwill be funded. Armed with this information, a competitive analysis, and aprototype solution, you will be able to justify their investment, build perceivedvalue, present your recommendations in a way that is almost irresistible, andsuccessfully close the contract.

Having the ability to recommend the correct course of action to your client has

tremendous value. In a market where it is difficult for companies to find qualifiedBusiness Intelligence consultants, the Executive Assessment and resultingpresentation gives you a chance to prove conclusively that you have the righttechnology and the right people to do the job.

2.3.2 Demonstration system setup

A demonstration system is typically set up in advance to show your customers

the attributes of the solution. The demonstration system can typically be set upwith a limited number of systems that are separate from the system that will beused by the production system.

You can set up ITCAM for WebSphere demonstration system using atwo-machine environment: one running the managing server and the otherrunning the application client with the data collector. This demonstration systemis typically running a test application that you can load onto it so that you can useITCAM for WebSphere to show monitoring processes and collect results.

The demonstration system enables your customers to evaluate whether thesolution suits their particular needs. Table 2-2 shows the tasks and estimatedtime for demonstrating the solution. Chapter 3, Demonstration of ITCAM forWebSphere on page 37 suggests some demonstration ideas.

Table 2-2 Solution demonstration task

2.3.3 Analyze solution tasks

After the customer agrees to use the solution in their environment, you must

decide how to implement it. These estimates would then be collected andimplemented into a contract or statement of work.

We discuss these tasks in detail in 2.4, Defining solution timing on page 21.These are our suggested tasks and order; you may complete the tasks in adifferent order or may omit or add tasks depending on the environment to whichyou implement the solution. Overall solution time might be influenced by theamount of skill and experience that you or your team have with the solution. Theestimate that we present is typically based on the following factors:

Has working knowledge of the operating system

Has good understanding of WebSphere Application Server and J2EE-basedenvironment

Understands J2EE application environment, with its components, such asEnterprise JavaBeans (EJB), Servlets, Java 2 Connector (J2C), JavaDatabase Connectivity (JDBC), and Web Services.

Understands WebSphere security concepts, such as Secure Socket Layer(SSL), LDAP authentication, and certificate usage

Has thorough knowledge of ITCAM for WebSphere

Depending on your skills and experience, the estimates we present might be toohigh or too low. Table 2-3 illustrates one method of approximating more realistictime estimates for your efforts, based on whether you or your team are new toeach skill area or could be considered experts. A novice is someone who hascompleted training in the skill area but has no hands-on experience. An experthas completed training in the skill area and has implemented ITCAM for

WebSphere projects.Table 2-3 Skill adjustment

For the detailed task breakdown, see 2.4, Defining solution timing on page 21.

2.3.4 Creating a contract

A contract or statement of work is a binding contractual agreement between youand your customer that defines the service engagement that you must performand the result that the customer can expect from the engagement. The contractshould leave nothing in doubt.

A statement of work should include:

Executive summary of the solution, which is typically a short (less than apage) summary of the solution and its benefit. You must specify any major

restrictions of the implementation, such as:

The solution is only implemented for finance application servers. The solution will be implemented in phases.

Assumptions, which lists all of the assumptions that are used to prepare the

contract and provide task estimation. Any deviation to the assumptions that isused will definitely affect the scope of engagement and must be managedusing the change management procedure. Typical changes include costchanges or scope changes.

Business partner responsibilities, which lists all of the responsibilities or majortasks that will be performed by you or your team to implement the solution.

Customer responsibilities, which lists all of the responsibilities or items thatthe customer must provide for you or your team to perform the engagement. If

you cannot obtain any item in the customer responsibilities, then a changemanagement procedure may be invoked.

Staffing estimates, which lists the estimated personnel needed to implementthe solution.

Project schedule and milestones, which shows the major steps, schedule,and achievement calendar that can be used to check the project progress.

Testing methodology, which lists the test cases to ensure that the projectimplementation is successful.

Deliverables, which provides tangible items that the customer will get at theend of the service engagement, including:

Machine installation Documentation Training

Completion criteria, which lists the items that, when provided to the customer,indicate that the engagement is successfully completed. For most services

engagements, this is probably the most delicate to define. Completion criteriacan be so general that you will be tied up providing the customer ongoingsupport for life. On the other hand, an inadequate completion criteria is oftenrejected by the customer fearing that you might back away from theengagement in an incomplete state.

See 2.5, Statement of work on page 29 for a sample statement of work.

2.4 Defining solution timingA profitable services engagement has to correctly identify the tasks that you mustperform and to adequately allocate the necessary time to perform them. This

section guides you on the tasks that you might need to perform for an ITCAM for


34/136


section guides you on the tasks that you might need to perform for an ITCAM forWebSphere solution implementation and the timing estimate. The estimate relieslargely on some basic assumptions:

Managed environment size: the number of data collectors that must beimplemented correspond directly with the load of the managing server and

the time needed for:

Installing the data collectors Designing monitoring server group and assigning operators Analyzing performance information

Application complexity: the number of servlets, EJB resources, andinter-server communication must be considered as they relate to the timeneeded for:

Analyzing performance information Determining performance bottlenecks Providing performance recommendations

Transaction rate of the application server would affect processing overheadon the managing server and have an impact on the collected performancedata size. A higher transaction rate requires a smaller sample percentage, butthis might prevent some of important transaction data from being collected, soyou should lengthen the analysis of performance information.

Table 2-4 lists our sizing assumptions.

Table 2-4 Sizing assumptions

Assumption Simple Moderate Complex

Number of data collectors < 5 5 - 10 10 - 20

Number of J2EE resources < 50 50 - 100 100 - 200

Inter-server communication N/A one to one interconnected

Transaction rate per data collector < 60/min 60 - 300/min 300 - 900/min

Important: You must be aware of any specific application problems or offendingtransactions that the customer is experiencing. It is common for the customer toassume that you can resolve this problem. Any such specific analysis must belisted in the assumption and factored properly for the time estimation. Ourestimate does not cover analyzing existing or specific problems.

Gather requirements

At the beginning of your engagement, you should meet with your customersto understand their proposed objectives and gather their requirements. First,you have to determine the functional requirements, which define the businessfunctions that the Business Intelligence system is going to provide. Youdetermine your requirements by developing a good understanding of thebusiness needs and of what you hope to achieve. For example, look at issues

such as business goals, purpose, and usage questions, such as who theusers are and how they expect to interact. It is important to gather theserequirements early and discover any challenges that might lay ahead while

they can still be dealt with easily. When you have determined the functionalrequirements, you can clarify the technical or system requirements.

The technical requirement involves spending time at the customer site todetermine and understand the available data sources. These data sourcesmight come in different formats, such as relational databases, spreadsheets,

text files, or even hard copies only. You need to be able to identify the fields ordata elements in these data sources and plan how these data elements willbe used in the target data mart. You also need to identify the schema or datausage changes from the supplied sample scenario, which is based on thenon-customized products.

The system requirement will be determined from the number and size of thedata sources and the expected goals that the business questions will cover.This information dictates the size and performance of the systems that will be

used in the solution. Design the solution

Topics that should be addressed include scalability, functionality, andperformance of this solution.

Design involves understanding the customers environment includinghardware, software, data volumes, special requirements, and operationalprocedures. It is necessary to identify and plan for any additional tuning ofsoftware that might be required because of the customers environment or

special needs. In addition, an analysis of the modifications made to thescenarios and reports must be performed. After you have designed theproposed solution and reviewed it with your customer, you are ready to begindevelopment of the offering.

Perform gap analysis

This task involves performing a gap analysis to give the customer an estimateof the development effort that is required to set up the solution. At its core, theanalysis seeks to determine what customizable components should be

extended, modified, or created. The number and complexity of customizablecomponents drives the size of the project and the required resources.

After you have designed the proposed solution and reviewed it with yourcustomer, you are ready to proceed.

The environment analysis service provides a high-level assessment of application environment. provide an initial assessment of application on the area of , which consists of thefollowing application servers: .

The monitoring of these application servers will be conducted over the period of for two weeks. At the end of the assessment period, will presentthe assessment finding, including:

Application server performance summary

Application highlight, such as load profile, and transaction rate

Performance highlights such as: potential bottleneck, excessive errors,deadlock

Environment tuning recommendations

Solution descriptionIn the environment analysis service, will provide a managing serverhardware that runs ITCAM for WebSphere managing server. ITCAM forWebSphere data collectors will be installed on s production serversfor assessment. The data collector will mainly run in level 1 monitoring, which willhave limited impact on your servers; lab testing shows a typical increase of

2%-3% of CPU usage for the J2EE application server.

The solution assumes that the managing server connection to the data collectorswould not go through a firewall.

During the assessment period, transaction performance information andapplication server performance information will be collected and stored in theITCAM for WebSphere managing server database.

will analyze the collected performance information and possibly performmonitoring with additional detail as needed. The analysis is performeddynamically and will not need a restart of the application servers.

At the end of the assessment period, will remove the data collectors from application servers and present the performance finding.
