The standard solution for a heavily used library that needs frequent space or directory adjustments is PDSE. Requires no monitoring or tweaking. You just have to make sure that the library is shared only within a sysplex.

Most of the shops I worked in we did compresses nightly or weekly based on usage and volume of changes. Most sysprogs did their planning of PDS's correctly, sorta directories weren't that big of an issue.

The other product by CA I forgot to ask about is PDSMAN. It has some nice features as well.

AFAIK, there were some similar products which 'prefetch' members for very large PDS to improve performance and there were threads on IBM-MAIN about handling PDS with very large count of members. >> </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
