Can anyone suggest me any way to increase the space allocated to an existing PDS, ( Any sugestions other than copying the members to a new PDS with more space and deleting the existing PDS) ?

Any TSO commands or anything like that?

Please help.

Thanks in advance.

Sebanpj,

Have you tried compressing the PDS.
The compress function recovers wasted space occupied by deleted or updated members (that is, space is made available for re-use).

Go to 3.4 then enter your pds name and put / in the command area and press enter. It will bring you to the panel from where you can perform various functions to the PDS. Look for compress option.

If this doesn't satify your requirement then the only way I can think of is copying it to another PDS and deleting and reallocating the original PDS with more space and copying the members back in from the backup.

It does rather depend on the current state of the PDS, if it is already in 16 extents then this can not be done without a complete rebuild.

A sneaky little trick .......
Assume PDS is FB 80 with 200 directory blocks, Prim CYL 1 Sec CYL 1

Writing in batch to a PDS can be used to make one off in flight space alterations. But, the dummy member must be quite big to force a secondary space allocation to occur.

It may be worth converting the PDS to PDSE. Take a look at this thread:
