As far as I know JES2 holds proclibs open normally. There may be a way to get it to close and re-open them. JES2 runs with the NDSI bit set in the PPT. Hence it does not issue ENQs for any datasets it allocates. Lennie

Is PDSE a solution? IEB COPY with DISP=SHR? We had a developer-facing local PROCLIB catenand. I routinely updated a member in background using ISPF EDIT ENQs. Once I found another developer's content in "my" member. She had courteously signed it. She explained that she had updated her member from a test system sharing DASD. Admin explained that MIM had crashed on that system at that time. MIM isn't fail-safe. But the price of fail-safe might be inability to IPL before MIM activates. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
