PXA_NO_SHARED_MEMORY

[Former Member]

Dear Guys

we are facing ABAP dump almost 1000+ can you please check and suggets solution

Short text

    600000 kilo bytes of shared memory for PXA not available.

What happened?

    When starting the R/3 System, 600000 Kbytes of storage space

    was required for the ABAP/4 program buffer (PXA), but this

    was not available.

    The system was started as an emergency system and is not fully

    operational.

    It is intended only for display and to eliminate errors.

    Under no circumstances should it be used for production

    purposes.

Error analysis

    The error probably occurred when installing the

    R/3 system.

    The return code of the SAP shared memory control was 1.

    The error reported by the operating system is:

    Error number..... 0

    Error text....... "No error"

How to correct the error

    Report the error to the group responsible for installing your

    R/3 System.

    The current size of the PXA was set at 554312 kilobytes.

    You can increase or decrease the PXA in the SAP profile. When

    doing this, please refer to the relevent instructions in the

    installation manual.

    You can use the utility program 'ipclimits' to display the

    available system resources.

    If the error occures in a non-modified SAP program, you may be able to

    find an interim solution in an SAP Note.

    If you have access to SAP Notes, carry out a search with the following

    keywords:

    "PXA_NO_SHARED_MEMORY" " "

I'm guessing that you've just changed some parameters and restarted the system, so go back to the old versions in /usr/sap/<SID>/SYS/profile and restart the system.  Then you can review the parameters at your leisure.
