REGION parameter

Include the REGION parameter on either your JOB statement or your EXEC statement to specify the region size (the amount of virtual storage used by the utility).

For the best performance, we recommend that you specify REGION=0M. Doing so enables the amount of virtual storage necessary to run the job to automatically be made available when the Online Consistent Copy job runs. If your data center does not permit you to specify REGION=0M, REGION=4M will usually ensure adequate storage.

Important

If you are running under Db2 Version 8 and you specify a value for REGION other than 0M, ensure that you have an appropriate value set for the MEMLIMIT parameter, either as your site’s default SMF option or on your JOB statement or EXEC statement.

We recommend that you have a MEMLIMIT value of at least 1 GB. For more information, see Setting-the-MEMLIMIT-parameter.
