GLYPH<SM590000> Problem : When you run the  arsdb -I ARCHIVE -vu  command from a BPXBATCH job, you  see errors in  STDOUT  or in the output of  arsdb -c , as shown in Figure 18-8. GLYPH<SM590000> Problem:  During installation and migration, when you run  arsdb -u -I or  arsdb -I  ARCHIVE -vx ARSSYS , you receive an error similar to Figure 18-9. – Check the  ARSSOCKD  region parameter. We recommend that you use  region=0 . Also,  check your TSO logon region size. Increase TSO, log out of TSO, and log back in. – When you run  export (x) , the contents of the ARSxxx table are exported to a flat file.  The command attempts to write the file to the directory in which the  arsdb  command  runs. Ensure that the user has write permissions for the file. Also, ensure that the user  has permissions for the  ARS_TMP  intermediate file. – Check the OMVS size to see whether it can be increased to the system limit  ( D OMVS,L ). Check your OMVS limits: MAXMMAPAREA and MAXSHAREPAGES. The  following example is output of the  D OMVS,L  command: Reason or resolution : Enter an  export  command for  DSNAOINI  in the BPXBATCH job, or  ensure that  export DSNAOINI='/etc/ars/cli.ini'  was defined. Verify that your  cli.ini  file is in this directory. Also, check that your  cli.ini  file references the correct DB2  subsystem, for example: Reason or resolution : Multiple resolutions can be attempted when you encounter this  error: The example shows current MAXMMAPAREA is 3107 and the maximum size that  MAXMMAPAREA can go is 4096. In our experience, version 8.5 required at least 3646  for the value of MAXMMAPAREA. In this example, the minimum memory size needed  for CMOD will be 3107 + 3646 = 6753. Therefore, you must increase the  MAXMMAPAREA from 4096 to a higher value, for example, 40960, to solve the  problem. Chapter 18.
