Two user IDs must be created in the IBM DB2 Universal Database to facilitate its operation as a primary data server:
LTMADMIN user – a TSO user, optionally named LTMADMIN, to:
Install, start, and stop the Replication Agent for DB2 UDB
Manage the Replication Agent system tables on the IBM DB2 Universal Database
The LTMADMIN user must have ALTER TABLE authority on any IBM DB2 Universal Database table to be marked for replication. This user ID issues an ALTER TABLE DATA CAPTURE CHANGES command on a primary table that is marked for replication.
The LTMADMIN user must have READ permission on the IBM DB2 Universal Database log files.
Replication Server Maintenance User – the user ID specified in the Replication Server create connection command for the primary database.
Any updates applied to the primary database by the Maintenance User are ignored for replication, unless the value of the LTM for MVS LTM_process_maint_uid_trans configuration parameter is Y.
LTM for MVS is a component of Replication Agent for
DB2 UDB and the other component is the IBM DB2 Universal Database
log reader.
Because the Maintenance User ID may be a user ID that can perform updates on the IBM DB2 Universal Database, it must conform to IBM z/OS user ID restrictions.
