Set ISM_ERROR_BLOCKS to determine the number of ISM Error Blocks allocated when Db2® initializes.
- 256 error blocks
- Permitted Values
- 1 - 1024 error blocks
If this value is too low, message ADHQ1219W might be issued. ISM Error Blocks communicate a storage constraint event in the product to the task that issues storage constraint messages. If you run out of ISM Error Blocks, the storage constraint message will not be issued. However, an abend table entry will be created to document this event. This is most likely a temporary situation and does not impact the performance of Db2.
