Choosing the correct logrec recording medium

You can choose where the system will record logrec error records. When a system is not in a sysplex, an installation can use a logrec data set, associated with an individual system, to record error records. An installation can choose to continue this type of recording by initializing the logrec data set before IPLing the system that will use it.

In a sysplex, however, because each system requires its own logrec data set, you might need to look at each logrec data set when an error occurs.

To eliminate the problem of having to manage up to 32 logrec data sets, an installation can choose to define one coupling facility logrec log stream. Using a coupling facility logrec log stream eliminates the following:

Running IFCDIP00 to initialize multiple logrec data sets
Handling full or emergency data set conditions
Scheduling the daily offload of logrec data sets
Concatenating multiple history data sets
Archiving logrec records
