This article describes how to split out an LPAR that is currently sharing ACF2 databases with other LPARs, so that it has its own ACF2 databases.
At this point, either an IPL will bring in the new databases, or an IPL can be avoided with the following technique:
Issue the following operator commands:
Issue the SWITCH command to change to the ALT databases. This is necessary because the PRIMARY DDSN is in use from IPL time, even though the dataset names are different.
A SWTCHKEY is needed that was added to the GSO OPTS record. If the SWTCHKEY has been forgotten, a new one will need to be added.
After the databases are switched to the alternates, then switch back to the PRIMARY which are now the new databases.
The SWTCHKEY prompt will occur again. Enter the SWTCHKEY.
The new active database names can be verified by issuing a TSO ACF, SHOW DDSN command.
Create ACF2 VSAM Databases Note that the INITIAL job described here only needs to be ran if the databases are empty. In the situation described above, the databases are already populated with information from the shared database.
