Looking for a solution:
I was looking for the last reference date for a dataset. I ran HLIST but it did not return me the details since the dataset was never backed up or migrated. Can anyone guide me where should I be looking for this date??
JCL:
| Code: |
//HLIST EXEC PGM=IKJEFT01,DYNAMNBR=30
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
HLIST DSNAME('XX.X.DT070412.OLDLOG') -
BOTH ODS('XX.X.XXX') |
Output:
| Code: |
1- DFSMSHSM CONTROL DATASET - MIGRATED DATASET-- LISTING ----- AT 08:30::47 ON 12/07/04 FOR SYSTEM=AABB
DATASET NAME MIGRATED LAST REF MIGRATEED TRKS QTY TIMES DS SDSP QTY LAST MIG
ON VOLUME DATE DATE ALLOC 2K BLKS MIG ORG DS 16K BLKS VOLUME
ARC0138I NO MCDS INFORMATION FOUND FOR DATASET XX.X.DT070412.OLDLOG
----- END OF - MIGRATED DATASET - LISTING -----
1- DFSMSHSM CONTROL DATASET - BACKUP DATASET-- LISTING ----- AT 08:30:47 ON 12/07/04 FOR SYSTEM=AABB
ARC0138I NO BCDS INFORMATION FOUND FOR DATASET XX.X.DT070412.OLDLOG
----- END OF - BACKUP DATASET - LISTING ----- |

The obvious answer would be to look in 3.4
Or does it have to be in batch? |

| The SYSREFDATE variable set by the (external) Rexx LISTDSI function, or the ZDLRDATE variable set by the ISPF LMDLIST service. |

next question (might be a very stupid one)... just for purpose of testing something i coded, is this field (last reference date) updatable (i mean thru a piece of code or manually(not expecting this field to be open for manual update, yet curious:) ))???.. i want to test a few conditions where the last access date for a dataset (PS) is 15 days ago... unfortunately... i deleted all my datasets just a couple of days ago just to save DASD  ... dont want to wait 15 days to test
i googled a bit but did not find anything substantial... if this is possible, is there a place where i would get such info (any doc, reading material, manual...) |

Technically yes (after all, how could MVS set this date if it were not modifiable?) However, we're talking serious system-level access here. I wouldn't try this without written permission from the storage management workgroup. |

why not temporarily change the elapsed period from 15 to 1 day ... then test the code tomorrow? |
