When conducting a Disaster Recovery (DR) test, it is crucial to ensure that System Management Facility (SMF) data is properly captured for analysis and validation. The DR floor system should be configured to capture SMF data using the following configuration in SYS1.PARMLIB(SMFPRM00):
## SMF Configuration in SYS1.PARMLIB(SMFPRM00)
```plaintext
ACTIVE /* ACTIVE SMF RECORDING */
BUFUSEWARN(25) /* ISSUE IEE986E WHEN XX% BUFFERS USED */
BUFSIZMAX(0512M) /* MAX SMF STORAGE BUFFERS */
DSNAME(SYS1.MAN1,SYS1.MAN2,SYS1.MAN3)
DDCONS(NO) /* COMBINE DUP EXCP FOR TYPE 30 */
EMPTYEXCPSEC(SUPPRESS) /* SUPPRESS EMPTY EXCP ENTRIES IN SMF30 */
INTVAL(15) /* SMF GLOBAL INTERVAL VALUE */
JWT(0030) /* 522 AFTER 30 MINUTES */
LISTDSN /* LIST DATA SET STATUS AT IPL */
MAXDORM(3000) /* WRITE AN IDLE BUFFER AFTER 30 MIN */
MEMLIMIT(1T) /* ALLOW 1 TB ABOVE THE 2GB BAR */
NOPROMPT /* DO NOT PROMPT OPERATOR FOR OPTIONS */
REC(PERM) /* NO TEMPORARY DSN'S IN SMF17 RECS */
SID(&SYSNAME(1:4)) /* SID SET FROM IEASYM00 SYSNAME */
STATUS(SMF,SYNC) /* WRITE SMF STATS BASED ON INTVAL() */
SYNCVAL(59) /* SMF GLOBAL SYNCHRONIZATION VALUE */
SYS(NOTYPE(4,5,19,20,32,34,35,40,99(1:9,12:14),100,205),
INTERVAL(SMF,SYNC),NODETAIL)
SUBSYS(JES2)
SUBSYS(OMVS)
SUBSYS(STC)
SUBSYS(TSO)
```
## Important Notes
- **Dataset Allocation:** SYS1.MAN1, SYS1.MAN2, and SYS1.MAN3 should each be allocated at **100 cylinders**.
- **Data Extraction:** The **z/OS team** will dump the data from SYS1.MANx datasets and reload it to the DASD for post-test processing.
- **Clearing the SMF Dataset:** Before running the DR1CLR job, ensure that the `/I SMF` command is issued to clear the SMF dataset.
By following this configuration, the DR test will successfully capture SMF data, allowing for comprehensive analysis and verification of system performance and recovery processes.
