These are some considerations regarding the Logrec Data Set:
1. You must initialize the Logrec data set before IPLing the system that will use it.
2. To initialize or reinitialize the Logrec data set, use the service aid program IFCDIP00.
3. To clear a full Logrec data set, use EREP. IFCDIP00 creates a header record and a time stamp record for the Logrec data set.
4. The logrec data set is an unmovable data set. If you attempt to move it after IPL using a program, such as a defragmentation program, your system will experience difficulty both reading from and writing to the data set.
