Council Structure


Statistics

• Directly employed staff 2,500+

• Fellows, PHDs,Master Students, Higher education institutes 2,400+

• Funding £220 m (2002/3)


Objective

• Potential for Different PeopleTools versions on the same node– Tuxedo Application Server– Weblogic web servers

• Facilitates progressive PeopleTools upgrade – Not ‘big bang’– Thorough testing


Initial Hardware

• Logical server setup • (40 users & low concurrent usage)• Database/Application Servers

– Sun 1 cpu 750mhz 1 GB Mem– Solaris and Oracle

• Web Server – Intel P3 600mhz 640 M Mem– Linux Red Hat


Why change?

• Delivered structure for servers does not lend itself to easy PeopleTools upgrade

• Initial logical server structure too unpredictable• Early tests, when extrapolated indicated system

failure with the introduction of self service• Increased user base 40+ to 2500+ requires

substantial increase in flexibility and robustness


• Also the technique appears to be officially supported• 717563: WebLogic: How do I install multiple instances

of WebLogic 5.1 • 200731212: How to Start Multiple WebLogic 5.1

Instances on Windows 2000/NT as Services (SP9)• 714889 - Installing and Removing the Multiple

WebLogic NT Services • Partially correct – but use beasrv.exe

• 720177 - How to configure Weblogic for multiple NICs?

And the GSC?


The Hardware Change

• Physical Server setup• Database Server

– Sun 2 cpu 750mgz – 3GB Mem

• Application Server – Compaq DL380 G3 2 cpu Xeon 2.4 ghz – 1 GB Mem

• Web Server– Compaq ML370 G2 2 cpu 1.4 ghz – 2 GB Mem

• Report Server– Compaq DL380 G3 1 cpu Xeon 2.4 ghz – 1GB Mem

• Running on a secure gigabyte network.


The Software

• Database – Oracle 8.1.7.4 on Solaris 8

• All other servers Windows 2000

• PeopleSoft HRMS 8.0 SP1

• PeopleTools 8.18

• SQR 8.18

• Crystal 8.0


• Old• New

Configurations


Configuration considerations

• Tuxedo

• Weblogic webserver

• Application Servers


Tuxedo

• Install once on each physical application server– One Important Configuration Consideration

• Some possible tuning opportunities


Weblogic Issues

• Only one Windows Webserver– Used for Dev, Test and Production

• On Windows, only one Weblogic installation per Weblogic version.

• Want to run different PeopleTools versions on same Weblogic installation – how to upgrade?


Web Server as deliveredD:\..Weblogic myserver has Weblogic.properties for everything cgi-bin clientclasses Applies to all myserver sites psftdocs HR80PRD has configuration.properties per site HR80CNV HR80UAT Peoplesoft8 public_html HR80PRD has signon.html per site HR80CNV HR80UAT serverclasses Applies to all myserver sites servletclasses Applies to all myserver sites

How to create a copy of myserver

• Copy the entire myserver directory to myserver_newserver• Amend the Weblogic.properties for the new server • Rename the directory in \psftdocs to the new server (say

newserver)• Amend the configuration.properties within this directory• Rename the directory under public_html to the new server

(say newserver)• Amend the signon.html within this directory• Delete access.log & other log files from

myserver_newserver directory


Weblogic Server

• Only one Weblogic server per physical windows server because of use of registry.

• These would be environmental variables on Unix.


Weblogic SP9

• Required in order to support multiple NT services.

• BEA Documentation uncharacteristically contradictory– beasvc.exe instead of install.exe and

remove.exe


MultipleApplication Servers

• Two new servers for Application Servers.– Still need different PeopleTools versions on

each servers• Multiple %PS_HOME%

– Only one Tuxedo installation per Windows server

• One configuration to support all domains– Application Servers and Process Schedulers under Tuxedo


Application Server

• One PeopleTools version per %PS_HOME%

• Need to set this variable before running psadmin


D:\... Psoft8 HR8SP1 all software under the one directory ActiveX api appserv HR80PRD HR80CNV HR80UAT prcs HR80PRD HR80CNV HR80UAT bin cblbin class crw

Application server as delivered


D:\... Psoft8 HR8SP1PRD Each instance has all the software ActiveX …… HR8SP1UAT ActiveX api appserv HR80UAT prcs HR80UAT bin cblbin class crw ……

Application Server Changed


Perceived Benefits

• Allowed us to progressively upgrade PeopleTools 8.14.10 to 8.18.x

• Different Tools versions in different environments. Permitting testing of tools versions through chain of environments.

• Substantial increase in system stability & scalability with the new structure

• Reviewed several physical/logical combinations


• PIA Location

• Weblogic NT Services

PIA Install quirks


• PeopleSoft PIA Installation process only creates service that runs default myserver

• Don’t run myserver, use it as a template only

Weblogic NT Services


Create NT Serviceper Web Server

• Used beasvc.exe to create and delete NT services for each Weblogic server.– Introduced at SP9– Do not use install.exe and remove.exe (up to

SP8)– If you have to delete a service you will

probably have to reboot the Windows server because the service table will lock.


First, do it without a service

• Get the various web servers starting from just an ordinary batch script.– Get the environmental variables for the JVM

right.– The put those variables into script to create

service.


Services

• Create service with batch script

• Recommend create – one batch script to install each server– one batch script to remove each server

– Caveat: deleting a service will lock the service table, and you have to reboot the whole server


installNtServiceXXXX.cmd [1/3]

set MYSERVER=myserverXXXX

set JAVA_HOME=C:\PROGRA~1\JavaSoft\JRE\132DB1~1.1_0

set WEBLOGICHOME=d:\ps\weblogic51

set CLASSPATH=%WEBLOGICHOME%\lib\weblogic510spboot.jar;%WEBLOGICHOME%\classes\boot;%WEBLOGICHOME%\eval\cloudscape\lib\cloudscape.jar

…



• This is variable comes from the batch script.

…set WEBLOGICCLASSPATH=%WEBLOGICHOME%\lib\weblogic510sp.jar;

%WEBLOGICHOME%\%MYSERVER%\servletclasses\entbase.jar;%WEBLOGICHOME%\%MYSERVER%\servletclasses\entssl.jar;%WEBLOGICHOME%\%MYSERVER%\servletclasses\gnu-regexp-1.0.8.jar;%WEBLOGICHOME%\%MYSERVER%\servletclasses\enthttp.jar;%WEBLOGICHOME%\%MYSERVER%\servletclasses;%WEBLOGICHOME%\license;%WEBLOGICHOME%\classes;%WEBLOGICHOME%\lib\weblogicaux.jar;%WEBLOGICHOME%\%MYSERVER%\serverclasses

…



…

set CMDLINE="-ms64m -mx64m -classpath \"%CLASSPATH%\" -Dweblogic.class.path=\"%WEBLOGICCLASSPATH%\" -Djava.security.policy==\"%WEBLOGICHOME%\weblogic.policy\" -Dweblogic.system.name=%MYSERVER% -Xrs PSweblogic"

%WEBLOGICHOME%\bin\beasvc.exe -install -svcname:"Weblogic Server 5.1.0 - %MYSERVER%" -javahome:%JAVA_HOME% -execdir:%WEBLOGICHOME% -extrapath:%WEBLOGICHOME%\bin -cmdline:%CMDLINE%


• No matter what you specify for the location the servlet files go to myserver!– (PT8.18.10)

• So don’t actually use myserver– Use it as a template

PIA Location


• Install the webserver changes into myserver

• Copy the java client binaries in the following 3 directories from myserver to myserver_newserver structure

– clientclass, serverclasses, servletclasses

• Copy peoplesoft8 sites from myserver to target server (myserverXXXX)– Now have vanilla configuration for that version of PeopleTools within

that server

• Retain backups of Weblogic.properties, configuration.properties, signon.html to compare with new files for changes

• Copy all files from peoplesoft8 into each site.

• Compare with backups to replace configuration values

Upgrading Tools for Weblogic


A Good Compare Tool

http://www.oneysoft.com/fcompare.htm


… and this is why

• Handle new parameters


• You can move an upgrade between different versions of PeopleTools– Do in 2-tier mode– Can connect to different patch releases

• 8.18.xx

– If different minor releases go via file• 8.14 -> 8.18• Just like a PSFT patch!

• Thus Application upgrades can overtake PeopleTools upgrade.

Upgrading


Other Bits

• Tuxedo and Terminal Services

• Unix Kernel Configuration

• Multiple NICs


Tuxedo& Terminal Services

• Don’t


Tuxedo ‘Unix Kernel’ Configuration


Queue & Maximum Message Size

• Typical Tuxedo Message ~100Kb

• If message > ¾ of message queue/max message size then written to disk– This is slow

• Provide room for queuing

• Recommend at least 256Kb– See 8.4 Red Paper for on-line performance


Number of Message Queues

• Number of queues = 2 * (

PSAPPSRV + PSQCKSRV + PSQRYSRV + PSSAMSRV + PSDBGSRV)

+ 7


Message Segments & Size

• Total Memory overhead of Message Queues= Maximum Number of Message Queues

* Maximum Message Queue Size

= Number Of Message Segments

* Size of Message Segment


Other bits

• Multiple NIC’s– Different IP address and/or different ports– Load balance across IP address

• even on same network card

• and on same physical NT server

• Hence multiple JVM without Weblogic clusters


Multiple NICs
