DFS3446I INDEX AREA IN MFS BUFFER POOL TOO SMALL. nnnn ENTRIES TRUNCATED

Explanation

The area in the message format buffer pool (MFBP) reserved during IMS initialization for the two indexes used by the MFBP manager is not large enough to accommodate the increased indexes that would result from the /MODIFY PREPARE or INITIATE OLC PHASE(PREPARE) command being entered.

System action

Processing continues.

System programmer response

If the /MODIFY PREPARE or INITIATE OLC PHASE(PREPARE) command completes successfully, enter one of the following commands:
  • /MODIFY ABORT
  • TERMINATE OLC
  • /MODIFY COMMIT
  • INITIATE OLC PHASE(COMMIT)

If you enter the /MODIFY ABORT command followed by the /MODIFY PREPARE , or the TERMINATE OLC command followed by the INITIATE OLC PHASE(PREPARE) command, the resident index ($$IMSDIR) might be made smaller.

If you enter the /MODIFY COMMIT or INITIATE OLC PHASE(COMMIT) command, the resident index will be truncated by the number of entries indicated in this message, but the switch to the inactive format library would continue. The reserved area for expansion of the indexes in the MFS buffer pool should be increased at the next IMS restart, or the requirements of the two indexes should be reduced. The reserved area is specified as an EXEC parameter (FBP=) in the IMS procedure.

The additional space requirement can be calculated as: 
12 x (1 + number of added MFS format blocks/12)
                plus
14 x (number of new $$IMSDIR entries)
