It is important to monitor performance of IDMS systems in order to ensure efficiency. Starting on CA IDMS v18.5 CA PERFMON and CA SYSVIEW combine to do
that in new ways.
On IDMS v18.5, the IDMSINFO address space was introduced. This facility allowed IDMS PERFMON to monitor performance in multiple CVs within the same LPAR.
This facility also opened up the possibility for IDMS SYSVIEW to see data from one or all CVs within the same address space. For SYSVIEW users, this
provides a new functionality that IDMS users may wish to utilize. This feature does require that CA IDMS v18.5 be installed at your site, but that is only
required on one CV. Once a v18.5 CV has been installed, this facility can then be used to access information for all CVs on R17.0 and higher.
For IDMS users who are not familiar with SYSVIEW, here is a list of some commands which are available within SYSVIEW to monitor IDMS systems:
IDMS MENU - Gives a list (which is also selectable) of all the IDMS Commands and sub-menus
IDMSLIST CA IDMS address space list
IDMS Set target IDMS address space
IDBUFFIO Buffer I/O summary
IDBUFFIO DETA Buffer I/O detail
IDDBASES Database overview
IDDBIOD Database I/O drivers
IDJRNL Journal activity
IDLINES Communication lines
IDLTERMS Logical terminals
IDLTRESU Logical terminal resource usage
IDPGMPL Program pools
IDRU System run units summary
IDRU DETAIL System run units detail
IDSCRMGR Scratch manager
IDSQL SQL usage
IDSTG Storage pool overview
IDSTGPL Storage pools
IDTASKS Active tasks
IDTRANOV Transaction overview
IDTSKPGM Task and program pool overview
IDMSTEST IDMS test utility
IDMS online reference
Anyone of the above commands can be suffixed with either SYSTEM or XSYSTEM to display the data for all CV's running on the same SYSTEM or all CV's running
cross system (XSYSTEM) . If neither suffix is specified, then the information displayed will be relevant to the selected default system only; this default
is specified with the IDMS command noted above.
For example: IDSTG XSYSTEM will display an initial panel like the following, with storage pool information for all of the IDMS systems at your site.
Many of the SYSVIEW commands, including the one above, display several screens worth of data, which can be accessed using the PF10 & PF11 PFKeys to
page left and right.
If you are a current user of IDMS PERFMON and would like this capability, you can look into purchasing the CA SYSVIEW product to access these commands. If
you are an IDMS user who uses SYSVIEW, you may want to purchase IDMS PERFMON in order to have access to this level of information.
