Updating database attributes and database descriptors dynamically
Use the type-2 command UPDATE DB to update certain attributes of a database definition dynamically. Use the type-2 command UPDATE DBDESC to update a database descriptor.
The DB and DBDESC parameters of the UPDATE command are valid only in DB/DC and DBCTL systems.
You cannot specify the UPDATE DB command or the UPDATE DBDESC command in an XRF alternate IMS system or in an FDBR region.
If you use the UPDATE DB command to change the status of a database that has a MODBLKS definition type, the definition type of the database changes to UPDATE, as displayed by the QUERY DB command.
If DRD is not enabled, you cannot use the UPDATE command to update runtime resource definition attribute values.
If a database is in use, you cannot update the status of the database definition.
Changing RESIDENT(N) to RESIDENT(Y) takes effect at the next restart.
