Improving upgrade performance of BMC Atrium Core

The following topics are provided:


If you created functional indexes at the database level of the AR System server, you must first save the information about these indexes and then proceed to remove them before you upgrade the AR System server. Create the indexes again after you upgrade the AR System server.

Deleting job history

From the Reconciliation Job Runs form, delete the reconciliation job history. Cleaning up the job history information improves the performance of the AR System server.

To delete the job history

  1. In a browser, open the RE:Job_Runs form in Search mode.
  2. Export these records to a file and then delete the records.
  3. In a browser, open the Application Pending form in Search mode.
  4. Export these records to a file and then delete the records.
  5. In a browser, open the Normalization Job Runs form in Search mode.
  6. Export these records to a file and then delete the records.

Improved upgrade installer performance

Shutting down the Reconciliation Engine and other applications related to AR System, such as Approval Server and Email Engine, before you upgrade improves the upgrade installer performance.

Peak efficiency through increased available virtual memory

If you are upgrading both the BMC Atrium Core and the BMC Remedy ITSM Suite of applications, BMC has found that having 4 GB of virtual memory available, as opposed to installed, provides the system with enough resources to process the upgrade at peak efficiency. However, if you are upgrading only BMC Atrium Core, then 2 GB of available virtual memory is sufficient.

Increasing the memory limit in an HP-UX Itanium computer

Before you start an upgrade on an HP-UX Itanium computer, you should review the currently running processes to see if the AR System server process, arserverd, is close to reaching the per process memory limit. The default per process limit on HP-UX is 2 GB. If the memory limit is close, then use the following procedure to increase its memory limit from 2 GB to 3 GB or to 4 GB.


If you are upgrading CMDB on HP-UX, BMC recommends setting these environment variables for malloc() tuning: _M_ARENA_OPTS=16:8 _M_SBA_OPTS=512:100:16 export _M_ARENA_OPTS _M_SBA_OPTS

To increase memory limit

  1. Do either of the following tasks:
    • Enter the following command to enable usage up to 3 GB:
      chatr +q3p enable arserverd
    • Enter the following command to enable usage up to 4 GB:
      chatr +q4p enable arserverd
      The chatr command changes the internal attributes and is used to modify the data page size for a specific executable.
  2. Enter the following command to configure your file system for large files:
    fsadm -F vxfs/dl large files


    To determine if a file system is configured for large files, use this command: usr/sbin/fsadm -F vxfs mount-point The output appears as either largefiles or nolargefiles.

  3. Set ulimit to unlimited:
    unlimit -c unlimited
  4. Using the sam or kmtune utilities, increase your kernel configuration variable, maxdsiz. This number can vary and is determined by the system administrator.
    The maxdsizkernel parameter controls the amount of private data each process can handle. Increasing this value prevents an "out of process memory" error.


    To increase the maxdsiz to 3 GB, you must increase the maxdsiz_64 to 3 GB.

Increasing the per process address space limit in a Microsoft Windows environment

If you have installed the AR System server on a 32-bit Windows 2000 or 2003 computer system, BMC recommends that you increase the per process address space limit from the default 2 GB to 3 GB before upgrading to BMC Atrium Core version 8.1.00. If required, you can restore the per process address space limit to the original value after installing the patch.

To increase per process address space limit

  1. Right-click the My Computer icon to open the System Properties window.
  2. On the Advanced tab, click Settings in the Startup and Recovery area.
  3. In the System startup area, click Edit to open the boot.ini file.
  4. In the boot.ini file, add the /3GB parameter to increase the memory limit to 3 GB:
    [HTMLUATatriumcoreIG:boot loader]
    [HTMLUATatriumcoreIG:operating systems]
    multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Programmatic name of the operating system" /3GB
  5. Save the boot.ini file.
  6. Restart the computer system.
