Preparing for Installation › Pre-Installation Considerations

Pre-Installation Considerations

The following presents important information you should note and precautionary measures we recommend:

• When upgrading from a previous release of CA Librarian, take backups of those libraries where you are installing CA Librarian before beginning the installation.
• Before executing any installation jobs, review the supplied member and modify the JCL to include site-specific information and to meet your site's JCL standards.
• All of the JCL supplied with CA Librarian allocates library space in blocks.
• The CA Librarian installation tape is in SMP/E "relfile" format, with the files created by the IBM IEBCOPY utility. The function modification identifiers (FMIDs) are loaded into relative files (source, macro, and load). CA Librarian consists of eight FMIDs, seven for CA Librarian and one for CA Profile.

  Each FMID has its own set of relative files, which are listed following:

  • CALJ440—5 (macro, source, load, JCL, and XML)
  • CALJ441—3 (macro and 2 load)
  • CALJ442—2 (macro and load)
  • CALJ441—2 (macro and load)
  • CALR440—1 (load)
  • CALU440—2 (macro and load)
  • CALU441—2 (macro, source, and load)
  • CALU442—3(macro, source, and load)
  • CALU443—1 (Japanese macro and load)
• Install CA Librarian in its own SMP/E target and distribution zones, for example, CAIT0 and CAID0.
• Accept CA Librarian so that you can run an SMP/E RESTORE for product maintenance.
• SMP/E USERMODs are used for customizing such CA Librarian facilities as the LIBRID defaults module and the LIB/CCF DB2 interface.

  Important! Never accept these USERMODs into your SMP/E system.

• CA Librarian takes advantage of various facilities that CA Common Services for z/OS and OS/390 provide. Specifically, you must install the S910 component, comprised of CAIRIM, CA-C Runtime, and CAISSF, before installing CA Librarian. CAIRIM, the Resource Initialization Manager, eliminates the need to IPL when installing the CA Librarian Access Method (LIB/AM). CAISSF, the Standard Security Interface, lets CA Librarian offer a standardized security interface. See the CA Common Services for z/OS and OS/390 Getting Started for installation procedures of the S910 component.
• CA Librarian uses SVC168 to implement the external security interface.
• In addition to the CSA requirements of CAIRIM, the CA Librarian Subsystem (LAM) acquires ECSA storage. The amount of ECSA storage is computed using the following formula: ECSA bytes equals ((MAXUSER plus 1) times 4) + 876 + ((number of wide record master files - 10) * 98)

  The MAXUSER parameter is defined in the IEASYSxx member of SYS1.PARMLIB. See the CA Common Services for z/OS and OS/390 Getting Started for CSA requirements for CAIRIM.

You can reduce the CSA storage requirements of CAIRIM by placing member LAMMVS in the LPA.
