CA PMO Features

Although CA PMO provides a wide variety of performance benefits, it is simple to install and to use, it does not require an IPL or system modifications, and it is invisible to end users. In addition to ease-of-use and convenience, CA PMO offers the following features:

CA PMO automatically chooses all of the private libraries that it will handle. You may specify particular private libraries that CA PMO may or may not process, but this is optional.
CA PMO automatically revises its managed list and creates new hash tables based on directory search activity. This allows CA PMO to enhance system performance for long periods of time without operator intervention.
CA PMO automatically detects and handles updates to libraries. This feature makes it particularly useful for user-owned libraries, because users delete, modify, copy, and move the members of these libraries on a daily basis. CA PMO communicates information about updates across systems using optional components CA PMO Cross-System (PMO/XSYS) and PMO XCF Enhanced Data Transmission Component (PMO/XCF).
CA PMO informs you of all of its activities. A monitor called PMOMON displays statistics on library directory searches on the system, along with savings of elapsed time, CPU time, and EXCPs. PMOMON also shows estimates of the monetary value of the benefits of CA PMO. It bases these estimates on the values that you assign to user time, CPU time, and EXCPs. PMOMON executes under TSO, CA Roscoe and as a batch program. If you want a library-by-library breakdown of directory search activity, CA PMO can generate a printed report that gives this information.
CA PMO extends the usage of the storage hierarchy by placing PDS directories into processor storage. This helps to provide better response time in SMS and non-SMS environments.
You can fine-tune the behavior of CA PMO by specifying various commands and parameters. For instance, you can designate groups of libraries that CA PMO must always handle, libraries that CA PMO may never handle, and you can determine baseline values that CA PMO uses when calculating various statistics. You can issue CA PMO commands at the operator console or in a batch job.
CA PMO can automatically refresh LLA, or it can warn the operator that an LLA refresh is needed. LLA refreshes can be limited to the actual libraries or members that are updated. Alternatively, to eliminate the delays caused by LLA refreshes, you can let CA PMO manage all of your LNKLST libraries and discontinue use of LLA. CA PMO can issue selective LLA refreshes to libraries that are part of a dynamic LNKLST set, as well as to the IPL LNKLST set.
