The database administrator can create replications from foreign copies in the same way as from SESAM backup copies (see section “Database replication”). Using a replication, you can:
free a DBH from pure read accesses during OLTP operation
repair an original database
reset an original database
create an independent database
If you create a replication or partial replication from a foreign copy then the space must not have the state “check pending” or “recover pending” when the foreign copy is created. The foreign copy is specified by your CAT-REC file.
You can use the RENAME parameter in the utility statement CREATE REPLICATION to accelerate the procedure. In this case, the replication is not created by copying the foreign copy but by a renaming operation. However, you should remember that this statement cannot be repeated even if an error occurs. Instead, it is necessary to create a new foreign copy.
