Changing the default recovery fault recording IEATDUMP data set name (RFRDSN)

In situations where an SDUMP cannot be used, the Fault Analyzer recovery fault recording feature requires that an IEATDUMP data set can be allocated by the abnormally terminating real-time analysis task. (For general information about the recovery fault recording feature, see Recovery fault recording.)

The default IEATDUMP data set name pattern is:

IDIRFRHQ.IDIRFR.&SYSNAME..D&YYMMDD..T&HHMMSS..S&SEQ.

To change the default data set name pattern, the RFRDSN setting in the IDIOPTLM configuration-options module is used.

The data set name pattern should include symbolic values to ensure that each allocated data set is unique. For example:

CL100'IDIHLQ.TDUMP.&&SYSNAME..D&&YYMMDD..T&&HHMMSS..S&&SEQ.'

For additional information about the use of symbols, see IDIOPTLM data set name symbol substitution.

Note: It is important to ensure that all users are able to allocate data sets with the pattern specified. See Managing recovery fault recording data set access for more information.

If it is desirable that the recovery fault recording IEATDUMP data set name pattern contains local date and time instead of UTC, then change &YYMMDD to &LYYMMDD and &HHMMSS to &LHHMMSS.

Use the special high-level qualifier NULLFILE to disable RFR TDUMP capture. If this name is used, message IDI0136W is issued.
