VSAM record management trace facility (non-RLS access) z/OS DFSMStvs Administration Guide GC52-1388-00 |
|
Use the VSAM record management trace facility (R/M trace) to record VSAM record management control blocks while VSAM is processing. GTF must also be active for the R/M trace function to write records to the trace data set. See Generalized trace facility for additional information on using GTF for tracing in VSAM. Use IPCS to print the GTF trace records. Because a trace work area for the data set being traced is obtained in private low storage at the time the data set is opened, activating R/M trace may cause some storage overload. Note: The VSAM Record Management Trace is a tool. Overlaying
or releasing VSAM's control blocks while the trace is active may cause
unpredictable results, such as, invalid trace information and various
abends.
