Hi,
Problem: How to find which DSN belongs to which 'team' ?
Scenario: Need to delete/minimize the use of datasets which starts with some HLQ.
My approach:
1. List all the datasets starting with some HLQ.
2. I can use LISTCAT LVL(HLQ) ALL to do this, but for me the output is quite nasty, when I'm just intrested to look for only data set names. So I used IKJEFT1A, this solves my problem a bit.
3. Now that some HLQ is used across teams, how to find which DSN belongs to which team here at my shop ?
My senior suggests that create an excel of DSNs starting with that HLQ & send across the team to check which DSN belongs to which Team, then wait for their mail. Ah..it's a donkey-work.
I'm thinking to use SMF records, something on the line of this topic..
http://www.ibmmainframes.com/viewtopic.php?t=29449&highlight=
So I need two suggestions:
1. Is there any alternate way, as I'm thinking to use SMF records, to do this or not?
2. If we can use SMF records, then I'm stuck up here in how to create SMF Data. looked here
http://publib.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/IEA2G281/2.3.1?DT=20080122045841
but couldn't get a good solution. Please suggest. |

Hello,

From smf you might find who (which teams) use each dataset name, but that may not identify which dsn belongs to which team.
One thing you might identify is a list of datasets that have not been referenced for some amount of time - a year, 2 years, 6 months. . . If you circulate a list and want responses, the way that i believe works best is to tell people that "the following datasets will be deleted on mm/dd/yyyy unless you send a reply that the dataset needs to be retained. Before doing anything, get a couple of backups of the potential scratch datasets. If "they" are not required to respond, many will not. . .

I suspect that you will want to read the existing smf data rather than create new smf data. |

Yeah, DCOLLECT is not too bad to use and does contain a whole lot more information than LISTCAT.
What about naming standards, as at most shops I've been involved in the naming setup/revamp the HLQ was DEV and the 2LQ was project id, so that makes it easier to identify which group is eating up all the space.
How about migrating datasets to ML2 and then seeing which ones get recalled. Not the most efficient I know, but it can give a good idea of what's going on |

Yeah, nearly same way it's here, but for that matter I've to be involved with all the teams & that makes this process 'manual' instead I'm thinking to do it using some JOB, any suggestion for that.

I think, as an Application Engineer I'm not autorized to do it, I need to contact my system guys? |

Can you just try the following...
HMIGRATE Command
You use this command to manually migrate a data set. You may want to do this a 'quick fix' to resolve space problems. At its simplest, the 3.4 line command is
HMIG DSNAME(/)
or
HMIG DSNAME(/) ML2 |

Hi,
This
works for me without (/). However, would like to know can we use it in Batch? |

Anuj,
Yes, you can run the HSM Dataset Level Command HMIG In batch.
Try this...
| Code: |
//STEP01 EXEC PGM=IKJEFT01
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
HMIG 'SYAM.TEST.FILE1' ML2
/*
// |
I believe that you have'nt lost your memory... ;-)

| Unfortunately only if he has ALTER access on the datasets being migrated. |

anuj,
If all you want are names, use
| Code: |
| LISTCAT LVL(HLQ) NAME |
instead of the ALL parameter. The listing is way fewer lines! |

I have a small question, If I want to list datasets starting with specific string is LVL work ?
Ex I have datasets like
MSA0455.FILE1
MSA0465.FILE2
MSA0488.FILE3
MSA0499.FILE4
In the above example, all datasets starting with "MSA04"
I tried with MSA04* in place of HLQ, but its failing. |

| Listcat uses whole nodes only. LMDLIST LISTID will use partial nodes. |

Why don't you try contact your security team either ACF2/RACF team in your shop?
Who ever be the mainframe team, every one should contact them for the access of HLQ for certain teams.
More over they can run a report on certain machine for all HLQ's and owenrs also. I think I have asked that type report before.
Check with you security admins team. |
