Setting up the MVS environment

Before you begin, check that your MVS environment is correctly defined to support CICSPlex SM.

If you want to record information about the installation and set up of your CICSPlex SM environment, you can use the checklists and worksheets provided in the library CICSTS31.CPSM.SEYUINST.
  1. Ensure that the CICSPlex SM SEYUAUTH library is defined to MVS as an APF-authorized library.
  2. Ensure that the CICSPlex SM SEYULINK library is included in the MVS link list.
  3. Increase the number of linkage indexes by 3 for CICSPlex SM. This is defined by the MVS NSYSLX parameter in IEASYSxx.
  4. Increase the number of common MVS data spaces by adding 6 for each CMAS. This is defined by the MVS MAXCAD parameter in IEASYSxx.
  5. Check the IEASYSxx member of SYS1.PARMLIB that you use for MVS initialization and make a note of the initialization values. These are referenced during the installation of a CMAS. For a detailed description of these values, see ../dfha1/dfha1b00178.htm#dfha1bg.
  6. Ensure that enough MVS auxiliary storage is available to support the data spaces used by each CMAS. A CMAS uses up to 9 MVS data spaces, which could mean an increase in auxiliary storage of as much as 100MB. For details on how to increase auxiliary storage, see Storage considerations.
  7. Assign a VTAM applid and sysid for each of the CMAS and Web User Interface regions. You can record these values on the planning worksheet.
  8. Reserve a TCP/IP port for the Web User Interface server. You can record the port number on the planning worksheet.
