RE: Shadow instance not starting during the phase START_SHDI_PREPUT

      Hi ,

      We are in the process of performing a EHP6 upgrade, And it is in the preprocessing phase and it is executing the step START_SHDI_PREPUT.
      The SUM tools is trying to start the shadow instance, but the instance in no comming up. And we are getting the below errors in DEVTRACE.LOG

      *** ERROR => e=28 semget(20165,1,2016) (28: No space left on device) [semux.c      499]
      *** ERROR => SemRq: Implicit SemInit failed. Key=65 [semux.c      1183]
      *** ERROR => Es2Cleanup: SemRq SEM_ES2_ADM (rc=1) [es2xx.c      1086]

      *** ERROR => e=28 semget(20127,1,2016) (28: No space left on device) [semux.c      499]
      SemKeyPermission( 28 ) = 0740 (octal)

      *** ERROR => ShmCleanup(62) failed 3 [mpixx.c      4451]
      MpiCleanup() -> MPI_ERROR: General error
      DpCleanupSharedResources: removing Semaphore-Management
      DpCleanupSharedResources: removing request queue

      And we have followed the snote 724713 and we have set the parameter pg_contig_disable=1 and created the project for users <sid>adm, ora<sid> as per the same note.

      Also, we have a RAM of about 64GB and swap space of 39GB

      Please can you help me know, what is lacking in this scenario.

      Best regards, SP

      Make sure the SAP system is stopped completely (primary and shadow) before you execute the cleanipc command. If you have stopped the SAP system before running this command then start the main system. Once the main system has been started then start the shadow system as follows. su - sidadm cd <Upgrade_directory>/abap/bin ./SAPup startshd   Regards RB
