Re: Command JES2 $AJ
I need information about command Jes2($AJ), submited for job in execution, i saw in SYSLOG, that it was requeued, carried on in another initiator passed to other step. Would id be normal behaviour ??? Help is wellcome. Jorge Campos TM SOLUTIONS What level of z/OS? Is the thread you copied here related to the BIND in VTAM issue ? If not, please create new threads and do not copy older ones that do not related to the topic. I have removed that part of the thread. $AJ - Release job. To determine what happened you need to use SYSLOG to trace the process. Find where the job is submitted in SYSLOG, then trace the job number to see what happened. AJ will not change the job to a new init after it has started. It could be someone or something (Automation tool?) did an HJ/EJ/AJ command. That requeues the job and then releases it. Then it might have gotten a new initiator. Find out all commands issued on this job and see what has occurred and when. If you have a product like OPS/MVS then you could use the OPS Browse Log function. It will filter syslog and help reduce the data to just what you want to look at. Also review the job number. Before the AJ command and After the AJ command, was it using the same job number? Do you have a scheduling product? Is it possible that the scheduling product did something? If you have SDSF it has a filter function that might help in this as well.

Re: Any HMC Gurus out there?
Doug: Thanks. I think you have the answer. I logged onto the HMC and viewed the console log. I was able to see regular messages indicating a time synchronization between the HMC and the z9 on a regular basis up to the time when someone logged on locally and fooled around with the IP addresses. I queried the client and found that they were messing around at that time and also fooled with the cabling. They will go and check things tomorrow morning and then we may be back on the air.

Ewing jcew...@acm.org said: I don't claim to be an expert on MIME Email syntax (only to know enough to be dangerous), but there is a definite end-line for a base64 encoded block (short line with trailing ='s). Yes. In order to append correctly you need to test whether there are 0, 1 or two trailing equal signs and decode the partial quantum, if any. You don't need to decode more than two characters. But if allowed, that would be certainly be a simpler solution than merging the two blocks into one (which requires at least a partial decoding of the last line of the first block to fill out that line) There's no need to fill out the last line. But, in the last case I received, this wasn't what the list server sent. It separated the second UTF-8 base64 footing from the previous base64 encoded block with an intervening multi-part separator line sequence. No. That may have been the intent, but a separator line contains the value of the boundary parameter from Content-Type. Since there was no boundary parameter, there can be no separator. A separator need not look like --===_4E91B300_==, and looking like that does not make it a separator. I thought once you added a multi-part separator, that required a new set of Contents headers, not to mention the other multi-part headers that were missing. Separator lines are part of composite MIME type. See RFC 2045 and RFC 2046 for details. In general, the message must have Mime-Version, Content-Type and Content-Transfer-Encoding header fields. A part that is not text/plain; charset=US-ASCII must have a Content-Type header before the blank line. In particular, if it is UTF-8 then it must have Content-Type text/plain; charset=UTF-8 In any event, what I'm receiving is definitely not making my Thunderbird client happy Nor would I expect any other e-mail client to render it properly; it is broken. -- Shmuel (Seymour J.)

No information was provided about where within IEFW21SD the program check occurred so it's hard to guess whether the 0C4 was due to bad user input or some system problem.

Am I missing something? IBM documentation states: Taking advantage of LBI: You can improve the performance of tape data sets by using the large block interface (LBI) for large block sizes. When the LBI is available, the COBOL run time automatically uses this facility for those tape files for which you use system-determined block size.
