Dynamic Extend of a Datacom area (PMF001 in this case) fails due to the following errors:
DB01705I - DYNAMIC EXTEND START PMF001 TRK 3,000 hlq.PMF001
DB01709I - EXTEND SIZE PMF001 CYL 0 - AREA FULL - JCL CYL 0
DB01702I - DYNAMIC EXTEND OF AREA PMF001 HAS FAILED
Per IBM documentation, the IEC031I message with D37-04 is returned when the primary space for the dataset is completely used and the dataset was not defined to use secondary space:
A data set opened for output used all the primary space, and no secondary space was requested. Change the JCL specifying a larger primary quantity or add a secondary quantity to the space parameter on the DD statement.
Release : 15.1
Component : CA Datacom/AD CA Datacom/DB
The area, PMF of DBID 001 in this case, was allocated without specifying secondary space, as shown on the CXX report of that area:
DYN.EXT.TRACKS - 0
SECONDARY CYLS -
A quick solution is to run an on-demand Dynamic Extend of the involved area, as outlined on "How to extend a CA Datacom area while the database is open" article.
Then, when it's possible, backup the area (if necessary), reallocate it specifying a secondary space quantity in the JCL, re-init and reload it.
