Few queries with GDGs here:
1. I want to know whether EMPTY uncatalogues all the previous generations including current one or all the generations excluding current when limit is exceeded.
2. I had specified EMPTY NOSCRATCH LIMIT(2). After adding third generation, when i did 3.4, i found it showing all the 3 generations still catalogued whereas actually it should be showing latest 2 only.
I ran pgm=IEHLIST with LISTVTOC Option for the first Generation G0001V00. I found it residing on SMS managed volume.
In SMS case, what is the purpose of LIMIT when still all the datasets are catalogued?
That is my doubt?
Thanks

It may be the combination of NOSCRATCH and EMPTY.
What status is G0001V00 from LISTCAT |

| The first generation will roll off, it just doesn't happen right away. Check back the next day. I have noticed at my shop the GDGs all start to roll out at a certain time of day. |

I got the answer here. I had specified EMPTY NOSCRATCH LIMIT(2) while defining GDG Base catalog.
After adding two generations I do LISTCAT for first and second generation.
The sysprint shows - STATUS------------ACTIVE
| Code: |
//IEHL01 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSIN DD *
LISTCAT ENTRIES( UPR4.TEST.GDG.G0001V00 ) ALL
/*
|
Now I add third generation and then do a LISTCAT for all 3 generations one by one. Though i still can see all the 3 generations in 3.4 dslist option panel.
Running LISTCAT again first and second generations gives me :
STATUS--------ROLLED-OFF
While against 3rd it is STATUS------------ACTIVE .
So, conclusion is : when limit exceeds, EMPTY causes all the generations ( whichever were present there prior to the offending generation was added) are rolled off i.e uncatalogued. However NOSCRATCH avoids getting them deleted.
Thanks everyone for your help,
