Schema Compare in Visual Studio


Schema Compare

Upcoming in Oracle Developer Tools for Visual Studio

– ODAC 12c

Compare two schemas in the same or different dbs

– Visually inspect differences using UI

– Generate a diff script for deployment purposes

– Can compare down to granularity of schema type (eg compare

all tables, or all packages, etc)


Schema Compare

Start with a local instance identical to production db

As development of .NET app progresses, local db

schema evolves to meet needs of app

Use SC as needed to inspect what has changed

When development is complete, use SC to compare

development vs production to generate diff script

Deploy diff script with app to bring production db up to

required version of schema

Typical Use Case of Visual Studio Developer

PDB Functionality in Visual Studio


PDB Functionality with ODP.NET

Requires Oracle Database 12c and ODAC 12c


PDB Functionality in Server Explorer

Pluggable Databases Node

– Menu: Plug, Generate Create Script

Pluggable Databases Node

– Menu: Clone, Unplug, Delete, Status, Generate Create Script


High Availability


ODP.NET FAN Uses ONS

Oracle Notification Service (ONS) replaces AQ

Benefits

– Faster, more scalable, eliminates firewall issue, supports Active

Data Guard, and consolidates publish/subscribe service

No code changes required

Requires ODP.NET 12c


Global Data Services

Extend RAC services to a global basis

– Access to FCF, load balancing, and affinity capabilities

– RAC, Active Data Guard, and GoldenGate can participate

Optimizes utilization, HA, and performance

No code changes

Requires Oracle Database 12c and ODP.NET 12c


Global Data Services Concepts

Without GDS

Sales Service Sales Service

GoldenGate GoldenGate

Sales Global Service

With GDS


Faster and More Graceful Planned Outage

Offline DB alerts ODP.NET of impending downtime

ODP.NET stops allocating and closes idle connections

– Connections returned to the pool are closed

Benefit – DB brought offline as quickly as possible

without end user disruptions

Set ODP.NET attribute “HA Events = true”



Transaction Guard

ODP.NET can determine whether a transaction

committed even upon some DB failure

Benefit – Ensure transaction commits at most one time

– No duplicates

Transaction outcome can be queried by the application

– OracleConnection properties return transaction id and status

– OracleLogicalTransactionStatus class



Transaction Guard


1. Request

2. Calls

4. Guaranteed Outcome

3. Enforce Outcome


Recoverable Error Detection and Recovery

After DB error, ODP.NET determines if failed transaction

is recoverable or not

– Returns error message if operation cannot be retried

ODP.NET OracleException property indicates if

transaction recoverable and can be retried

Benefit – Easier to determine next step in transaction

recovery process



Connection Timeout Error Improvement

Returns specific error when no connection allocation

possible due to max pool size limit

– Previously, error was vague

– Can distinguish CP errors from other client and server errors

Benefit – Easier to identify and resolve CP-related error

No code changes to use

– If already capturing error messages

Requires ODP.NET 12c


Ease of Application Migration


Implicit REF CURSOR (RC)

ODP.NET retrieves result set without explicit RC

declaration nor RC metadata in .NET config

Can retrieve multiple implicit RCs

– ExecuteNonQuery – Returns array of RCs

– ExecuteReader – Returns DataReader, each accessible via

calling NextResult

Benefit – Simplifies retrieving result sets from PL/SQL

Entity Framework will still require result set metadata in

.NET config


Boolean Data Type

ODP.NET OracleBoolean data type

– Can be used with PL/SQL Booleans

Benefit – Eases parameter binding

– Stored procedures

– Entity Framework Function Imports


Identity Column

DB automatically generates auto-incrementing value as

needed

– Supports ANSI’s IDENTITY keyword

Benefit – Easier to set up auto incrementing values,

such as for primary keys

Integrated with ODT and ODP.NET

– E.g. ODT: Create table with auto-incrementing Identity column

– E.g. ODP.NET: Add row without explicitly providing identity value


Large VARCHAR2, NVARCHAR2, and RAW

ODP.NET VARCHAR2, NVARCHAR2, and RAW data

types now can be up to 32 KB in size

Benefit – Remain with fundamental data types even with

larger data

– No need to modify schema or use more advanced type


Return Row Count Per Array DML Iteration

ODP.NET returns number of rows affected for each input

value, not just the total number of rows affected

New OracleCommand.ArrayBindRowCount property

– Returns number of affected rows for each executed array bound

DML iteration

Benefit – Provides more info on DML correctness and

efficiency


Managed ODP.NET


Managed ODP.NET vs. Unmanaged ODP.NET

One assembly for both 32-bit and x64

Easier side by side deployment

Deploy smaller and fewer binaries

– Before: 150 MB

– After: Less than 10 MB

Easier patching process

Fully integrated with Code Access Security

Managed ODP.NET Deployment Concepts

Option 1: single configuration file deployment

– .NET config file contains TNS and sqlnet.ora settings

i.e. Machine.config, web.config, app.config

Option 2: multi-file configuration

– .NET config file

– Tnsnames.ora and sqlnet.ora

Option 3: no configuration files

– Store connect info in Data Source attribute



Deploying Managed ODP.NET


Managed ODP.NET Deployment Concepts

.NET config file

– Similar settings as unmanaged plus TNS and sqlnet.ora settings

– Managed -

– Unmanaged -

Tnsnames.ora and Sqlnet.ora

– Same attribute settings

– Most, but not all attributes are available


Unmanaged to Managed Migration

Application migration process

– 1. Replace Oracle.ManagedDataAccess.dll reference to project

– 2. Modify namespace(s) to Managed ODP.NET

– 3. Change .NET config settings for Managed ODP.NET

Include sqlnet.ora settings

Managed ODP.NET APIs same as ODP.NET APIs

– Initially, Managed ODP.NET will not support all ODP.NET

features

– Plan is eventual feature parity



Porting to Managed ODP.NET
