If you need to temporarily suspend replication of DDL, you can use the pdb_setrepddl command to disable replication of DDL. When you are ready to resume replication of DDL, you can use the pdb_setrepddl command to enable replication.
DDL replication is enabled, by default.
When you set the value of pdb_setrepddl to enable, all DDL in your primary database is replicated.
To replicate DDL, Replication Server must have a database-level replication
definition with replicate DDL set in the definition.
For details on creating a database-level replication definition,
see the Mirror Replication Agent Reference Manual.
