In the book "Implementing REXX support in SDSF", there's a sample called @SYSCMD.
It'll wait and pick up the output. A more gung ho way would be to build a vary command processor in assembler, where the PGM makes use of Channel End or Device End interrupts. - Vignesh Mainframe Admin -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of J R Sent: 22 April 2014 22:43 To: [email protected] Subject: Re: Slow vary commands processing Scott Ford said: "Baby, I am a tad confused here. Vary commands also can be dependent on what is going on inside the system. i.e.; CPU , I/O ...many things. Secondly, why is the speed of execution as issue ? Do you have processes that are dependent on the timing of these varies ??? " Baby Eklavya previously said: "For eg , we had an abend yesterday where STEP 1 issues a vary command against a set of volumes . And STEP 2 runs an ICKDSF to init the volume . It fails saying the volume is not offline . " I doubt that CPU utilization would affect only VARY commands. However, commands are executed asynchronously, so there is certainly no guarantee (nor even likelihood) that they will complete any time (FSVO) soon. In the case of VARY OFFLINE, any current activity on the volume(s) would have to quiesce. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN MARKSANDSPENCER.COM ________________________________ Unless otherwise stated above: Marks and Spencer plc Registered Office: Waterside House 35 North Wharf Road London W2 1NW Registered No. 214436 in England and Wales.
