IBM Health Checker for z/OS

IBM® Health Checker for z/OS® checks the current active z/OS and sysplex settings and definitions for an image and compares their values to either those suggested by IBM or defined by you. It identifies potential problems before they affect your availability or, in worst cases, cause outages.

The z/OS UNIX checks are as follows:

USS_AUTOMOUNT_DELAY: Evaluates the delay times of the configuration.
USS_FILESYS_CONFIG: Evaluates the configuration of the file system.
USS_CLIENT_MOUNTS: In a shared file system configuration, checks whether each file system that can be locally accessed by a non-owning system is indeed locally accessed.
USS _HFS_DETECTED: Checks all mounted file systems and issues a message if any file systems of type HFS are found.
USS_PARMLIB_MOUNTS: Verifies that file systems that are specified in the BPXPRMxx member were mounted successfully. It checks the values that were specified in BPXPRMxx at initialization time. If BPXPRMxx was updated after initialization with different values, those changed values are not included in subsequent checks. Only the initial values are checked.
USS_MAXSOCKETS_MAXFILEPROC: Evaluates whether the MAXSOCKETS and MAXFILEPROC statements in the BPXPRMxx member are set high enough.
USS_PARMLIB: Determines whether there are differences between current system settings and the settings defined in the BPXPRMxx member. If a difference is found, an exception message is issued. You will receive a report that lists the differences.
