Requirements for using BMC ISR

Consider the following requirements before using BMC ISR:

  • BMC ISR uses a zSeries file system (zFS)

    You must have read, write, and execute authority on the zFS (also known as superuser authority or root user authority).

    Note

    BMC ISR has removed support for the IBM hierarchical file system (HFS), in accordance with the suggestion by IBM to migrate from HFS to zFS starting with z/OS 1.7.

  • The zFS file system must be mounted before sending or retrieving a BMC ISR request. For more information about the file system, see About the zFS file system used by BMC ISR.

  • BMC ISR service packages are in a compressed format

    You must have authority for GIMZIP and GIMUNZIP.

  • Space requirements for retrieved service packages

    Before retrieving your service package from the BMC ISR server, ensure that you have adequate space on your UNIX file system on an IBM z/OS platform. The service package is provided in compressed format; however, the space that GIMUNZIP (which extracts data sets and files from the archive files) requires on the UNIX file system is two to three times the size of the package.

    To determine the amount of space that the uncompressed files require, review the file attributes contained in GIMFAF.XML (in the downloaded package). For details, see the archive files section of the IBM manual SMP/E V3R4.0 for z/OS Reference.

    If you choose to separate the GIMUNZIP data sets (SMPNTS and SMPWKDIR), SMPNTS must contain space equivalent to the size of the downloaded service; SMPWKDIR must contain space equivalent to two times the size of the service package.

  • BMC ISR does not support the use of DDs for SMP/E zones; DDDEFs must be used.

  • Integrated Cryptographic Service Facility (ICSF) requirements

    When you submit a request, BMC ISR assumes that the ICSF is running. If ICSF is not available, you must include the SMPCPATH and SMPJHOME DD statements in the following jobs:

    • $E05XTRT before submitting a request

    • $J05RETV before retrieving the service package

    SMPCPATH specifies a directory in the UNIX file system where the SMP/E Java classes reside. SMPJHOME specifies a directory in the UNIX file system where the Oracle Java runtime resides. The $E05XTRT and $J05RETV jobs also indicate where to include these DD statements. For more information about these statements, see the IBM SMP/E commands manual.
