For PowerExchange to read change data from Db2 logs, the user ID that you specify for database access must have SYSADM or DBADM authority. Usually, you specify this user ID in the UDB CAPI_CONNECTION statement in the dbmover.cfg file.
If the user has SYSADM authority, ensure that the user also has SELECT, INSERT, UPDATE, and DELETE permissions to the PowerExchange capture catalog in the source database. You can use the GRANT DATAACCESS statement to grant these permissions on the database to the user.
