Making online changes for HALDBs

The following restrictions apply for IMS online change with HALDB partitions.

• During an ALL or MODBLKS system definition, you cannot redefine a database that is currently defined as a HALDB partition without performing a cold start of IMS. A cold start is required even if you delete the database online. That is, if you delete a HALDB partition, you cannot reuse that database name for any database that you plan to add during an ALL or MODBLKS online change without an IMS cold start.
• You cannot convert a database that is defined during an ALL or MODBLKS system definition into a HALDB partition without performing a cold start of IMS. A cold start is required even if you delete the database online. After the IMS cold start, you must redefine the database as a HALDB partition.

These restrictions do not apply for a HALDB master database.
