Hello Ramakrishna,

I suggest you to kindly go to OS level and restart the saposcol service and check if that works.

<b>No values and/or problems with shared memory</b>

Check whether saposcol belongs to user 'root' and whether the authorizations are correct: -rwsr-x---

Because the values of saposcol must be visible for all R/3 systems/instances on a host, saposcol writes data in the shared memory segment with key 1002. This shared memory segment must not be changed (for example, by setting profile parameter ipc/shm_psize_1002). In all profiles, check whether the parameter ipc/shm_psize_1002 is set. If it is, this parameter must be removed from the profiles ---> Note 37537.

For further details please refer SAP Note 189072 , 726094.

Regards,

Prem

Hi ,

The SAPOSCOL service may be down on the server. Just restart it and it should be OK.

Shared memory unavailable suggests that the error is related to lack of memory resources, it could also be memory fragmentation issue.

Take this up with your system administrators and take their advise, server reboot could also solve your problem.
