XCOM Shared Memory in use 

------------------------- 

 

XCOM Shared Memory is in use. 

Please close all XCOM processes before proceeding for upgrade. 

Installer will now exit 

PRESS <ENTER> TO ACCEPT THE FOLLOWING (Exit): 

Environment:
XCOM r11.6 SP01
Resolution:

If the xcomd deamon is not running and you have uninstalled the previous release, then you want to issue the following commands:

   ipcs -m  --> this command will show you the shared memory segments. If XCOM has a segment you will see:

       ------ Shared Memory Segments -------- 

       key               shmid     owner  perms  bytes      nattch status 

       0x00000019  131072   root     666     338251   1 

 

   ipcs -s ---> this command will show you the semaphonres. If there is a semaphore for XCOM then you will see this: 

        ------ Semaphore Arrays -------- 

        key              semid   owner   perms nsems 

        0x00000000 0          root      600    1 

        0x00000000 65537   root      600    1 

        0x00000019 262146 root      666    1 

 

"0x00000019" is XCOM's key. If you see the above then you need to get those cleared out. Please check with your Linux administrator.
