Set the z/OS UNIX definitions in BPXPRMxx

Define OMVS=xx in the IEASYSxx parmlib member to specify which BPXPRMxx parmlib member should be used during IPL.

MAXPROCUSER specifies the maximum number of processes that a single z/OS® UNIX user ID can have concurrently active. Set MAXPROCUSER in SYS1.PARMLIB(BPXPRMxx) to 50 or higher. This setting is intended to be a system-wide limit, because it should be active for each client that uses Developer for z/OS.

These values can be checked and set dynamically (until the next IPL) with the following console commands:
  • DISPLAY OMVS,O
  • SETOMVS MAXPROCUSER=50
Note:
  • The MAXPROCUSER value suggested here is based upon users having a unique z/OS UNIX user ID (UID). Increase this value if your users share the same UID.
  • During the SMP/E install of z/OS Explorer Extensions, you were advised to place the code in a separate file system (zFS of HFS) and update BPXPRMxx to mount this file system during system IPL. Included is a repeat of the sample mount command in case this update still must be done:
    MOUNT FILESYSTEM('#dsn')
       MOUNTPOINT('-PathPrefix-usr/lpp/IBM/zee')
       SETUID                     /* preserve APF auth */
       MODE(RDWR)                 /* can be MODE(READ) */
       TYPE(ZFS) PARM('AGGRGROW') /* zFS, with extents */
    /* TYPE(HFS) */               /* HFS, auto. extent */
  • During the SMP/E install of z/OS Source Code Analysis, you were advised to place the code in a separate file system (zFS of HFS) and update BPXPRMxx to mount this file system during system IPL. Included is a repeat of the sample mount command in case this update still must be done:
    MOUNT FILESYSTEM('#dsn')
       MOUNTPOINT('-PathPrefix-usr/lpp/IBM/akg')
       MODE(RDWR)                 /* can be MODE(READ) */
       TYPE(ZFS) PARM('AGGRGROW') /* zFS, with extents */
    /* TYPE(HFS) */               /* HFS, auto. extent */
