LOAD_NO_ROLL ABAP dump , work process moved to private mode after EHP8 upgrade -

Hello All,

Since we upgraded our ERP system from EHP4 to EHP8, we are getting frequently LOAD_NO_ROLL ABAP dump and many of the work process went to private mode in one of the application server.

Please advise us whether we need to change any sap memory parameter value.

OS : AIX

SAP - EHP8 FOR SAP ERP 6.0

Oracle - 12C

Total RAM - 36GB

Total Paging :32GB

Current Parameters

Regards

Subbu

    Hi Subbu,

    Your system is now running a SAP kernel 74x.

    Check out this WIKI page.

    Hi Subbu.

    1. Could you share the dump as text format attachment? Dumps are getting any specified or all transaction / reports?

    2. You can enable the trace to check the over all transaction level performance tuning

    Regards

    Hi Subbu,

    LOAD_NO_ROLL dumps normally refer to Extended Memory exhausted on relevant application server. This information is also written on the dump:
    Short Text
    No roll storage available when loading a program.

    Component............ EM
    Location.......... SAP-Server <server_name> on host <host> (wp 72)
    Version.............. 37
    Error code............ 7
    Error text............ Warning: EM-Memory exhausted: Workprocess gets PRIV


    When Extended Memory is exhausted, work processes start taking Heap Memory, entering into PRIV mode. That's why you're having many work process entering into private mode in one of the application servers.

    You can confirm that Extended Memory on that server has been exhausted checking transaction ST02. If 'MaxUse[KB]' value of Extended memory has reached 'In Mem[KB]' value, you need to increase Extended Memory size, based on application server resources.

    Regards,
    Raquel
