Migrating Oracle content side-by-side

Transfer Oracle data from your IBM® Connections 4.5 or 5.0 databases to the new 4.5 or 5.0 databases as part of migrating to version 5.5.

About this task

Transfer data from your IBM Connections 4.5 or 5.0 databases, described here as the source databases, to the new 4.5 or 5.0 databases, described here as the target databases. When the data transfer is complete and you validate the new databases, you can update them to version 5.5.

Important: You can continue to use your 4.5 or 5.0 databases until you are ready to move to IBM Connections 5.5. Any data that you generate after the database update is not migrated to the new environment.

Note: Run the predbxferxx.sql and postdbxferxx.sql that are in the 5.5 GA build and not the 4.5 or 5.0 build. Depending on which database version you are migrating from, xx might be:

45
45CR4
50

To update the databases, complete the following steps:

Procedure

Using the IBM Connections 4.5 or 5.0 database wizard, create target databases on a separate system from your source databases. The new databases host your data for migration to the 5.5 deployment.

The procedure is described in the IBM Connections 4.5 Knowledge Center topic: Creating databases with the database wizard

Or the IBM Connections 5.0 Knowledge Center: Creating Oracle databases

Note: If the 4.5 or 5.0 database wizard is not on the system that hosts the target databases, copy it from the system that hosts IBM Connections 4.5 or 5.0.
Bring the target Databases up to the latest Cumulative Refresh (CR) level for the code stream as described in the IBM Connections 5.0 Knowledge Center topic: Updating 4.0 and 4.5 Oracle databases manually

Prepare the target databases to accept data from the source databases. Remove constraints from the target databases by running the following SQL scripts from the IBM Connections 5.5 package:

Notes:

Run these SQL scripts before you transfer data to the target database.
Run each script from the same directory that you use to create the target database.
IBM Connections uses the ojdbc6.jar database libraries, which are already on the target database server:

Repeat the following procedures for each application that you are migrating:

For each application, change to the directory that contains the relevant SQL file.
Enter the following commands:
1. sqlplus /NOLOG
2. conn system/password@SID
3. @SQL_script.sql
Where
- password is the password for the user system.
- SID is the Oracle System Identifier for IBM Connections.
- SQL_script refers to a SQL script from the following table.
Note: Run the predbxferxx.sql commands that are in the 5.5 GA build and not the 4.5 or 5.0 build, wherexx might be:
- 45
- 45CR4
- 50

Using the IBM Connections database transfer tool, transfer data to the target databases:
1. Create the directory DBT_HOME on the target database server. This directory temporarily stores transferred data.
2. Be sure to use the new version of the dbt.jar file and copy it from the connections_root\ConfigEngine\lib directory to the DBT_HOME directory on the target database server.
3. Create an XML configuration file for each component database to be transferred under the DBT_HOME directory and add the following content:
```
<dbTransfer xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<database role="source" 
driver="JDBC_driver" 
url="JDBC_url" 
userId="database_admin
schema="application_db_schema_name"
dbType="dbType"/>
<database role="target"
driver="JDBC_driver"
url="JDBC_url"
userId="database_admin" 
schema="application_db_schema_name" 
dbType="dbType"/>
<table sourceName="TABLE_TO_SKIP" exclude="true"/> 
</dbTransfer>
```
  Where
  JDBC_driver is the following type:
  - oracle.jdbc.driver.OracleDriver
  JDBC_url is the following types
  - jdbc:oracle:thin:@host_IP:port:SID
  Note: Where
  
  host_IP is the IP address of the database server.
  
  port is the port number of the server.
  
  SID is the Oracle System Identifier for IBM Connections
  
  application_database_name is one of the following values:
  
  Activities: OPNACT
  
  Blogs: BLOGS
  
  Communities: SNCOMM
  
  Dogear: DOGEAR
  
  Files: FILES
  
  Forum: FORUM
  
  Home page: HOMEPAGE
  
  Metrics: METRICS
  
  Mobile: MOBILE
  
  Profiles: PEOPLEDB
  
  Wikis: WIKIS
  database_admin is the user ID of the database administrator.
  application_db_schema_name is one of the following values:
  - Activities: ACTIVITIES
  - Blogs: BLOGS
  - Communities: SNCOMM and CALENDAR
    Note: To migrate Communities data, the dbt command needs to be run twice; the first time for the SNCOMM schema, and the second time for the CALENDAR schema.
  - Dogear: DOGEAR
  - Files: FILES
  - Forum: FORUM
  - Home page: HOMEPAGE
  - Metrics: METRICS
  - Mobile: MOBILE
  - Profiles: EMPINST
    Note: If you use the TDI-related table EMP_UPDATE_TIMESTAMP, it does not need to be transferred. Add the instruction: <table sourceName="EMP_UPDATE_TIMESTAMP" exclude="true"/>.
  - Wikis: WIKIS
  dbType is the following value:
  - oracle
  The entry <table sourceName="TABLE_TO_SKIP" exclude="true"/> instructs dbtransfer to skip a table. This instruction is of limited use as most table content is expected to transfer.
4. Prepare the JDBC driver of the target databases:
  - Use the JDBC driver on the target database server.
  - Ensure that the Oracle driver on your system has the same version number as your Oracle database server. IBM Connections does not support the Oracle 10.2.0.1 JDBC driver.
5. To transfer the data, run the dbt.jar file. Do not add spaces in a series of file names:
  - Linux:
    JAVA_HOME/bin/java
    -cp DBT_HOME/dbt.jar:
    ORACLE_HOME/jdbc/lib/ojdbc6.jar
    com.ibm.wps.config.db.transfer.CmdLineTransfer
    -logDir DBT_HOME/logs
    -xmlfile DBT_HOME/dbt_config_file_name
    -sourcepassword source_db_password
    -targetpassword target_db_password
    Where
    
    JAVA_HOME is the path to the Java™ JDK.
    
    dbt_config_file_name is the name of the XML configuration file you created for the dbt.jar file
    
    logs is the directory where log files are stored. Create the logs directory before you run this file
    
    ORACLE_HOME is the path to the Oracle installation directory.
    
    Run the command on a single line; do not add extra spaces. For example, multiple file names are entered as filename.jar:filename.jar without a space between the file names. The command looks similar to the following when run as a single command (edited to your specific configuration):
    JAVA_HOME/bin/java -cp DBT_HOME/dbt.jar:ORACLE_HOME/jdbc/lib/ojdbc6.jar com.ibm.wps.config.db.transfer.CmdLineTransfer -logDir DBT_HOME/logs -xmlfile DBT_HOME/dbt_config_file_name -sourcepassword password -targetpassword password
  - Windows:
    JAVA_HOME\bin\java
    -cp DBT_HOME\dbt.jar;
    ORACLE_HOME\jdbc\lib\ojdbc6.jar
    com.ibm.wps.config.db.transfer.CmdLineTransfer
    -logDir DBT_HOME/logs
    -xmlfile DBT_HOME/dbt_config_file_name
    -sourcepassword source_db_password
    -targetpassword target_db_password
  Run the command on a single line; do not add extra spaces. For example, multiple file names are entered as filename.jar;filename.jar without a space between the file names. The command looks similar to the following when run as a single command (edited to your specific configuration):
```
JAVA_HOME\bin\java -cp c:\DBT_HOME\dbt.jar;ORACLE_HOME\jdbc\lib\ojdbc6.jar com.ibm.wps.config.db.transfer.CmdLineTransfer -logDir c:\DBT_HOME\logs -xmlfile c:\DBT_HOME\dbt_config_file_name -sourcepassword password -targetpassword password
```
  When the transfer is complete, you can restart your 4.5 or 5.0 deployment to minimize service downtime.
  
  Note: Data that is generated after you restart the 4.5 or 5.0 environment is not migrated.

Reapply constraints to the target databases:

For each application, change to the directory that contains the relevant SQL file.
Enter the following commands:
1. sqlplus /NOLOG
2. conn system/password@SID
3. @SQL_script.sql
  Where
  - password is the password for the user system.
  - SID is the Oracle System Identifier for IBM Connections.
  - SQL_script refers to a SQL script from the following table:
Note: Run the postdbxferxx.sql commands that are in the 5.5 GA build and not the 4.5 or 5.0 build, wherexx might be:
- 45
- 45CR4
- 50
