Windows clustered server: Configure JCR collation support

JCR collation is recommended when the language locales of the users do not natively collate correctly in the DB2 database and when language locale correct ordering is important.

Prerequisites

Windows clustered server: Install DB2

Windows clustered server: Modify DB2 database properties

Windows clustered server: Create groups and assign users

Windows clustered server: Create DB2 databases

Windows clustered server: Set up DB2 automatically or manually

1. Stop the WebSphere Portal server.

2. Copy the following files from the WebSphere Portal server to a temporary directory on the DB2 server:

   PortalServer/jcr/wp.content.repository.install/lib/wp.content.repository.install.jar
   

   wp_profile/PortalServer/jcr/config/registerCollationUDFTemplate.sql
   

3. Set up collation on the database where the JCR domain is located. Log in to the database machine with a user ID that is authorized and configured to use the appropriate DB2 instance.

   For example, a common user ID is db2inst1.

   1. Change to the directory db2home/function.

   2. Run the command:

      db2home/java/jdk/bin/jar -xvf temporary location/wp.content.repository.install.jar icm/CollationUDF.class

   3. Change to the temporary directory where you copied the files in a previous step.

   4. Edit registerCollationUDFTemplate.sql and change all SCHEMA references to the JCR schema; for example, JCR.

      The value set for SCHEMA should match the value set for jcr.DbSchema. .

   5. Connect to the JCR database...
      db2 connect to jcrdb user user_ID using password

   6. Run the script:

      db2 -tvf temporary location/registerCollationUDFTemplate.sql

   7. Disconnect from the JCR database.

   8. Restart the DB2 instance.

4. Verify the UDF is registered properly.

   1. Log in as the db2instanceID.

      1. Open a DB2 terminal window.

      2. Run the following command...
         db2 connect to jcrdb user user_ID using password

         Connect to the JCR database as a database runtime user with the user ID and password for the WebSphere Portal JCR data source.

      3. Register the UDF: values schema.sortkeyj('abc','en')

5. Edit...
   WP_PROFILE/PortalServer/jcr/lib/com/ibm/icm/icm.properties

   Add the following section to the end of the file:

     # Enable/Disable collation support for all DB2 platforms   # Disabled by default   jcr.query.collation.db2.enabled = true 
     # Database specific collation mappings   
   # These mappings apply map a Java locale name into a collation name   
     # supported by the underlying database.
     # Example mappings for DB2 platform 
     # English   jcr.query.collation.en = en
    
     # Swedish   jcr.query.collation.sv = sv
   
     jcr.query.collation.zh = zh
     jcr.query.collation.de = de
     jcr.query.collation.da = da
     jcr.query.collation.hu = hu
     jcr.query.collation.jp = jp
   

6. Start the WebSphere Portal server.
