OGG-00511
Cannot access DDL history table. DDL schema owner is {0}. It must match schema used in DDL installation as well as GGSCHEMA parameter in GLOBALS file. Currently logged user {1} must have been given privileges to access DDL history table
Cause
The database user by which the process is running cannot read the GGS_DDL_HIST table (history table).
Action
Make certain that the schema that is specified in the error text is the same one that is specified for the GGSCHEMA parameter in the GLOBALS file (and that this parameter exists there). If this parameter is correct, make certain that the specified user has full SELECT and DML privileges on the table. The privileges can be granted by running the role_setup.sql script to create the default GGS_GGSUSER_ROLE role, and then by granting the role to the Extract user.
