Hi everyone,
could anyone please advice how using a REXX exec I can get information (creation date, last reference date, used space) about migrated, VSAM and tape datasets? I tried using DCOLLECT but I don't have sufficient access and also the datsets HSM.MCDS & HSM.BCDS which are required for getting the above information for migrated datasets are not cataloged in my system. I also came accross a command LISTP which seems to be able to give the information I am looking for but when I tried, it says TSO command not found. I know that by putting the RECALL option in LISTDSI we can first recall the migrated datasets and get the information but I don't want the dataset to be recalled. |

The only way to get this info is either from the DCOLECT M records, or from the MCDS D records. When VSAM is migrated, it becomes a PS dataset so not even catalog info would give you what you want.
I am very surprised that the CDS datasets are not catalogued. The surely should be. Perhaps they have a different HLQ other than HSM.
To get the DCOLLECT info you will need to talk to your security people to allow you the access, probably the same to access the MCDS too, although if you are using RLS for the CDS you may not be able to REPRO out the MCDS to a flat file.
Can you not use a backup version of the MCDS dataset, restore it with Dfdss to a new name and then use that to REPRO out and analyse ? |

HI Expat,
Thanks for the info.....I also cud not fing the CDS datasets but with other HLQ I was able to figure that out.....I also copied down a bakup to my file.
Now the problem is I do not know what are the MCDS D records and also what information I will get about migrated datasets as all info I am getting is not in displayble format. |

| You need to get a hold of the DFSMShsm disgnostics manual to see the layout of the record formats, and that yill give you everything that you need to know. |

Hi,
here is some JCL that should assist
| Code: |
//ALLOCATE EXEC PGM=IEFBR14
//ALLOCATE DD DSN=OUPT-FILE,
// DISP=(,CATLG,DELETE),
// UNIT=(SYSDA,3),
// SPACE=(TRK,(500,150),RLSE),
// DCB=(RECFM=FBA,LRECL=121)
//*
//**********************************************************************
//*
//HLIST EXEC PGM=IKJEFT01,DYNAMNBR=30
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
HLIST DSNAME('USER.CAL') BOTH ODS('OUTPUT-FILE')
|
or
| Code: |
HLIST LEVEL(Userid) BOTH ODS('output-file')
|

Hi,
my understanding of 2k blks and 16k blks is that HSM writes in 2k blks when it writes to MIGRAT1 and 16k blks when it writes to MIGRAT2.
