IC76003: SERVER NEEDS TWO RESTARTS FOR DBMEMPERCENT OR DBDIAGLOGSIZE CHANGES TO BECOME ACTIVE

APAR status

• Closed as program error.

Error description

• The following memory settings exist without DBMEMPERCENT being
  specified in the dsmserv.opt file:
  
  (These values are found in the output from "db2 get dbm cfg show
  detail" issued as the db2 instance owner).
  
  Description  : Size of instance shared memory (4KB)
  Parameter    : (INSTANCE_MEMORY)
  Current Value: AUTOMATIC(363892)
  Delayed Value: AUTOMATIC(363892)
  
  Add DBMEMPERCENT to the dsmserv.opt file:
  dbmempercent 30
  
  Halt and restart the server, the server reports:
  ANR1383I Memory usage by the database is limited to 562MB.
  
  If you issue the "db2 get dbm cfg show detail" again, you will
  see that the values have not been applied:
  
  DB2 config reports:
  Description  : Size of instance shared memory (4KB)
  Parameter    : (INSTANCE_MEMORY)
  Current Value: AUTOMATIC(363892)
  Delayed Value: 143872
  
  Halt  and restart the server a second time. No ANR1383I message
  is  displayed, and if you reissue the "db2 get dbm cfg show
  detail" command again, you will see that the new values have
  been applied.
  
  DB2 config reports:
  Description  : Size of instance shared memory (4KB)
  Parameter    : (INSTANCE_MEMORY)
  Current Value: 143872
  Delayed Value: 143872
  
  
  For the DBDIAGLOGSIZE option check the "db2 get dbm cfg" output
  for the DIAGSIZE parameter.
