>Gee, you do I/O, you wait ... [snip] Sure. I don't know if there is a CICS service to do I/O to some non-CICS dataset, or if it was simply tolerated. Actually, a wait only affects other transactions in the same CICS region as the will have to wait, too. I remember that in the early releases of OpenEdition / OS/390 UNIX CICS and IMS both stated that they do not allow UNIX services from within transactions because teh waits that could result.
No matter whether waits are allowed or tolerated there is big differece between a transaction doing an I/O to some dataset or UNIX file and a transaction doing an I/O to some named pipe. In the later case there is a second *independent* process involved. And this process might run or not when the CICS transacion does its I/O (to the pipe). Long waits may result and this must be acceptable to the transaction's purpose. -- Peter Hunkeler Credit Suisse ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
