Hi all,

is there any utility to give the information of the GDG files? should give which generation has data and which does not have.

i used LISTCAT but this utility did not give me the information i wanted. if i have 5 generation i want to know in which generation have data and which does not have data.

thanks,

No, LISTCAT will not tell you which files have data.

You need to test each file individually to see if the file is populated.

individually yes i know that!

but like we use 3.4 option and when we give the base name to the right it will show tracks% .

if tracks% is 0 then dataset is empty
if tracks% is100 then it has some data...

so i want this information by a utility (not individual checking).

Arvind, what you're looking at through ISPF 3.4 option is individual dataset usage data; you can replicate this in batch via the DCOLLECT command in IDCAMS.

can you give me the syntax for getting info of all the generation for GDG base. i got one but i want correct syntax (because i did not used this earlier. pls).

Code:
//STAP0015 EXEC PROC=IDCAMS
//SYSUDUMP DD SYSOUT=*
//DCOLOUT DD DSN=VINF0PRD.BLVB04.B8D300.DCOLLECT,DISP=OLD
//SYSIN DD *
DCOLLECT OUTFILE(DCOLOUT) VOLUMES(*) NODATAINFO
/*

Please help me to get the correct syntax.
thanks,

From the manual: Quote: NODATAINFO
says that no data set information records are generated or written to the output data set. Use this parameter if you want only volume information generated for the given volumes or storage groups.

Abbreviation: NOD
Try changing this to NOVOLUMEINFO since you are specifically wanting data set information.

You don't; you have to look in the output file for the GDG files one by one to get the space usage. DCOLLECT works on volumes or storage groups but then you have to do some filtering based on what you're looking for.
