Well the term "internal compress" is wrong. There is no compress for PDSE libraries and SMS will automaticly release/reuse the space when no connection exists. So what is a connection/connector in terms of a load library in the DFHRPL concat? What about space reuse (connector) for a PDSE in the LNKLST?
Assume CICS is up from IPL to IPL (7*24) 1. CICS load a program object from DFHRPL using BLDL/DESERV. 2. In some cases CICS does a compress because of SOS conditions 3. Someone binds the program object 4. CICS require the program again and will reload using the TTR from the BLDL/DESERV 5. PDSE returns back the "old" version of program object because there was no NewCopy so far 6. Someone issue a CICS NewCopy Is the connection to the "old" program object gone after the NewCopy and SMS will now reuse the space for the old program object? No Newcopy: Does this mean the space for old program objects will be releases/reused after CICS is down during the IPL?

Space vacated by deleted members is simply recycled for new members; existing members remain in place. This still leaves an issue of fragmentation; I don't know what addresses that. If I migrate and recall a PDSE, does it come back optimized, defragmented, compressed, whatever; even as happens with a PDS? > Another issue is NON-SMS and PDSE > I was pleased to learn, relatively recently, that temporary PDSEs are supported. I assume this means something broke the logical chain of PDSE implies SMS implies catalogued implies non-temporary. Are temporary PDSEs another instance that requires the SMS address space to be active? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
