Is there a way to know when the gdg versions are created? We have a gdg base with 100 generations. Most of the generations are in migrated status and it takes a long time to recall them to see the creation date in 3.4. I want to know the creation date without recalling the generations.

Thanks

Misi

LISTCAT does not recall the dataset.

Misi,

The following DFSORT/ICETOOL JCL will give you the desired results. If you have syncsort at your shop then change the pgm name to synctool in step0200.

A brief explanation of the job. step0100 is used to issue listcat command against the gdg base.

Step0200 takes in the listcat input and formats to get the creation dates of the versions and the base also.

Code:

//STEP0100 EXEC PGM=IKJEFT01                       
//SYSTSPRT DD DSN=&L,                             
//            DISP=(,PASS),                       
//            SPACE=(CYL,(5,5),RLSE),           
//            DCB=(LRECL=80,RECFM=FB,BLKSIZE=0)   
//SYSTSIN  DD *                                   
  LISTCAT ENT('USERID.GDGBASE') ALL   
//*   
//STEP0200 EXEC PGM=ICETOOL                               
//TOOLMSG  DD SYSOUT=*                                   
//DFSMSG   DD SYSOUT=*                                   
//IN       DD DSN=&L,DISP=(OLD,PASS)                     
//T1       DD DSN=&T1,DISP=(,PASS),SPACE=(CYL,(5,5),RLSE)
//T2       DD DSN=&T2,DISP=(,PASS),SPACE=(CYL,(5,5),RLSE)
//CON      DD DSN=&T1,DISP=OLD,VOL=REF=*.T1               
//         DD DSN=&T2,DISP=OLD,VOL=REF=*.T2   
//OUT      DD SYSOUT=*
//TOOLIN   DD *                                                     
   COPY FROM(IN)  USING(CTL1)                                       
   SORT FROM(CON) USING(CTL2)                                       
//CTL1CNTL DD *                                                     
   OUTFIL FNAMES=T1,                                                 
   INCLUDE=(4,7,CH,EQ,C'NONVSAM',OR,1,8,CH,EQ,C'GDG BASE'),         
   OUTREC=(17,44,5X,7C'0',80:X,SEQNUM,8,ZD)                         
   OUTFIL FNAMES=T2,STARTREC=2,INCLUDE=(37,8,CH,EQ,C'CREATION'),     
   OUTREC=(49X,53,4,58,3,80:X,SEQNUM,8,ZD)                           
//CTL2CNTL DD *                                                     
   OPTION EQUALS
   INREC FIELDS=(1,49,50,2,CHANGE=(1,C'19',C'0',                     
                                     C'20',C'1',                     
                                     C'21',C'2'),NOMATCH=(C'0'),     
                 52,5,80:X,81,8)                                     
   SORT FIELDS=(81,8,ZD,A)                                           
   SUM FIELDS=(50,6,ZD)                                             
   OUTREC FIELDS=(1,49,50,6,ZD,PD,LENGTH=4,80:X)                     
   OUTFIL FNAMES=OUT,                                               
   OUTREC=(1,44,C' IS CREATED ON: ',50,4,DT1,EDIT=(TTTT-TT-TT),80:X)
/*                                                                   


The output from this job is :

Code:

USERID.GDGBASE                  IS CREATED ON: 1999-07-23
USERID.GDGBASE.G0001V00         IS CREATED ON: 1999-07-24
.....
USERID.GDGBASE.G1232V00         IS CREATED ON: 2004-04-20


Hope this helps...

Cheers

Kolusu

Hi,
Try using ISMF. Use option 1: Dataset. do 2-3 PF11's you can see the creation date.

HLIST will give you the last referenced date. You can specify a dataset to write the output of the HLIST command to as a parameter rather than trying to outtrap it in rexx which won't work.

But, Kolusu, superk said above, "LISTCAT does not recall the dataset."

Kolusu,
I think, I am seeing counter-statements here.

Your example uses a LISTCAT and superk said that LISTCAT does not recall a dataset. So, I was wondering if your job would work when couple of generations are migrated.

I am not sure, if I can easily find out a base with generations migrated. So, I could not test your job.

Cogito,

Listcat gets the information from the catalog(VTOC) , so it does not matter if the GDG versions are migrated. Superk also mentioned the same , that the poster can run a Listcat command on the GDGbase , so that he can get the create date of the versions.

Hope this is clear

Kolusu
