RSMDATA SUMMARY subcommand output

The RSM summary report provides information on central storage usage on a system-wide basis. The report also displays information about any unusual RSM conditions. Because some report sections appear only when certain conditions exist, all the sections that are described might not appear in your report.

The top section of the report displays the usage statistics, in decimal, for the following types of frames:

Tot real: The total number of real frames
Below: Real storage frames below 16 MB
Prf real: Preferred real frames
Prf B: Preferred real frames below 16 MB
Above: Real storage frames above 16 MB, but below 2 GB
Prf A: Preferred real frames above 16 MB, but below 2 GB
Dbl real: Double frame pairs
Qd Real: Quad frame groups

V=R Region:: If there is a V=R region, the second section of the report lists the number, in hexadecimal, of the first and last real frames in the V=R region. It also lists the total number of frames in the V=R region, in decimal. If there is no V=R region, a message appears.
Total disabled reference (DREF) pages in real:: The next section of the report displays the total number, in decimal, of disabled reference (DREF) pages in central storage.
Number of 64-bit common memory pages:: The next section of the report displays the total number, in decimal, of high virtual common pages backed in real, fixed, DREF and auxiliary storage (DASD and SCM).
Number of shared data pages:: The next section of the report displays the total number, in decimal, of shared pages in real (fixed or pageable) and auxiliary (DASD and SCM) storage.
Number of fixed 1 MB-pages:: The next section of the report displays the total number, in decimal, of fixed 1 MB-pages in real storage.
Number of pageable 1 MB-pages:: The next section of the report displays the total number, in decimal of 1 MB-pages in real storage (fixed or pageable).
Number of fixed 2 GB-pages:: The next section of the report displays the total number, in decimal, of 2 GB-pages in real storage.
Number of 64-bit common memory pages:: The next section of the report displays the total number, in decimal, of high virtual common pages backed in real, fixed, DREF and auxiliary storage (DASD and SCM).
Some RSM requests are suspended waiting for unavailable real frames:: If any RSM requests are suspended because they are waiting for frames, the number of requests waiting for each type of frame appears, in decimal.
IARnnnnns messages: Messages appear for any unusual conditions. See z/OS MVS Dump Output Messages for message explanations.
IBM® internal diagnostic information:: The last section of the report contains diagnostic data useful to IBM.
