VSAM Analysis workspace
The predefined VSAM Analysis workspace shows the percentage of strings being used to process I/O requests to this VSAM file and details about the VSAM data sets allocated to a selected CICS® region.
The predefined VSAM Analysis workspace contains the following views:
- The VSAM String Utilization bar chart
- The VSAM Analysis table view
Because CICS dumps, traces, transient data, and auxiliary temporary storage reside in VSAM data sets, you can use the VSAM Analysis table view to locate a VSAM data set experiencing string waits or excessive control interval (CI) or control area (CA) splits. Such conditions can adversely affect CICS performance. You can view current data collected on demand for these items:
- The number of data CA and data CI splits for the VSAM data set
- The number of index CA and index CI splits for the VSAM data set
- The numbers of new data and index extents taken by the VSAM data set
- Mode of access CICS uses to open the data set
- Type of VSAM data set
- Total time outs from VSAM data sets in record-level sharing (RLS) mode
- The status of the VSAM data set
- Statistics for the number of strings defined, the strings being used, and the strings with requests queued against them
- The local shared resources pool (LSR) pool ID of the LSR file for a selected CICS region
It also provides a link to the VSAM Analysis in 3270 view of the OMEGAMON 3270 interface. When you right-click a link icon in the VSAM Analysis table view and select VSAM Analysis in 3270, you must enter your terminal session user credentials in the dialog and click OK. A terminal view is displayed within the workspace, with the appropriate details.
Note that this predefined workspace link to a 3270 session has an associated sample script. You should review the script prior to using it in your environment.
