You can convert full-function databases offline by using
the CONVERT command.
About this task
Databases must be offline to use this method. You must
manually /DBR your databases before running the conversion job.
When the IMS management of ACBs is enabled:
New database definitions must exist in the IMS catalog staging data sets before running the IMS
HALDB Toolkit job.
The shadow database is unloaded by using the active database definition obtained from the IMS
catalog directory data sets, then reloaded by using the pending database definition obtained from
the IMS catalog staging data sets.
Restriction: Databases with logical relationships (except
for indexes) are not supported.
Specify the ONLINE parameter as
ONLINE(N). ONLINE(N) is the default if you do not specify this parameter. The
following parameters are required to perform offline conversion:
//IHCSYSIN DD *
CONVERT DBD(xxx) ONLINE(N)...
You can also refer to the following examples to code CONVERT JCL statements and command
parameters:
Manually /DBR your databases before running the conversion job.
After the conversion process is complete and you are certain that you will not need to revert
the database to its non-HALDB state:
You can delete any DFSMDA members for the old database.
If the Integrity Checker utility of IMS Library Integrity Utilities is active in your
environment, you can delete the RDE for the old database by using the LICON utility.
