Configuring Unicode for DB2® databases

You must configure each database used in the IBM® Connections deployment for Unicode. Configuration for Unicode must be set before Connections installation because it cannot be set after installation.

Procedure

You must perform the following steps on each DB2® instance in the deployment:

Stop any WebSphere® server connected to the DB2® database you are configuring.
Log in to the DB2® server as the DB2® instance owner.
Open the DB2® command window.

Run the following commands in sequence:

db2set DB2CODEPAGE=1208


db2stop force

db2start

Run the following commands to check the new configuration:
```
db2set
```
This should return DB2CODEPAGE=1208. If not, it is not configured correctly and you should try Step 4 again.
