Issue/Introduction

Question:

 We got a notification from our DBA that the print space report in our CV:

SYSTEM.DDLDCLOG 8.85 % FREE PGSIZE 5,064 DCLOG WARNING

Can you please advise the detailed steps we need to take to expand the space before we run out of space?

Resolution

Answer:

The DDLDCLOG file is a special system area. The reason for this space discrepancy is that after offloading the log, IDMS marks the log as offloaded but we don't erase the records, we simply rewrite over the existing data. Thus the PRINT PAGE will always be around 93-95% full, except after you FORMAT the area.

Using the PRINT SPACE utility to see how full the log area is will be misleading. To look at the amount of space used in the CV LOG, I'd suggest using the DCMT DISPLAY LOG command. This will give you a better idea of the space usage in the LOG.
