The fully supported program product StarTool can modify secondary space of any PDS, allocated or not. Its ancestor, the PDS Command--available on CBT--has performed this function for decades. I've never heard of a failure.
Note that modifying secondary space does not touch the allocation at all, only the external data set attributes. The next time space is needed, the system will add a secondary extent as needed. Be careful though: some PDS uses may not allow expansion. In particular, link list data sets will not see a new extent automatically. JES2 proclibs may require a close/open sequence--not a JES2 restart--to pick up an additional extent. . .

Say you have many PDS(not PDSE) datasets that for whatever reason were never allocated with secondary extents(not LLA datasets). Is there a tool that can change the dataset secondary allocation from 0 to some other number easily? Don't want to have to reallocate the datasets. I don't see that the PDS can do it, nor does it look like IDCAMS can do it... ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
