Re: Best method
This is only required/useful when using WAKEUP in combination with a WAKEUP file. And, the exec using WAKEUP must be celver enough to use CP SLEEP or alike to effectively pass midnight. Here's what I wrote about the problem in our RxServer HTML documentation. *Midnight Processing*|-- Precautions must be taken to make WAKEUP safely pass midnight. This section explains why the WAKEUP-file contains 2 times the command *MIDNIGHT*. How does WAKEUP use its event file ?|-- WAKEUP can only use one timer for all time bound events. So, before it can set the next wake-up time, it must check all events and select the first one to come. Then it calculates how long it can go to sleep to reach that time, and sets the timer accordingly. Each time our server executes the *WAKEUP*command, the file is read again to find the next event. In following example, all events run only once a day to ease the explanation. Remark as well that there is no need to have the records sorted on the time field. ALL 00:01:00 08/30/01 MIDNIGHT ALL 23:59:01 08/28/01 MIDNIGHT ALL 06:00:00 08/30/01 SCANMSGLOG ALL 20:00:00 08/29/01 EXEC VCMAINT CPYREXX The first three fields are important in this explanation. - Field 1, in this case, tells that all events must be executed every day. - Field 2 tells at what time of day it must be triggered. - Field 3 is updated by WAKEUP and indicates when it the event was triggered the last time. By checking this field, WAKEUP knows whether the event was already triggered today or still needs to be executed. For records that have to executed once a day, WAKEUP looks at fields 2 and 3: 1. If it is now later than the time of field 2: - if the date in field 3 is equal to today, then the event has already been executed. - if the field indicates an earlier day, then the event is triggered immediately to clear the backlog. 2. If the current time is earlier than the one in field 2, the event becomes a candidate for selection. This leads to one important aspect and some side effects. - WAKEUP will not detect the first event planned for next day, and if the last event for today has been executed, there is nothing anymore that will set the timer. Our server will thus only be woken up by other events than a timer interrupt. WAKEUP is very likely to miss the first event of the next day. Therefore, all servers using a WAKEUP file must have an event triggered closely to midnight, whereby the server can then enter a *CP SLEEP* to let midnight pass by. WAKEUP will then detect the records again, as a new day has arrived. For this reason, the server kernel has the function *MIDNIGHT*. When the server starts up, it checks whether this function is defined in the file, and insert the record if it is missing: ALL 23:59:01 08/28/01 MIDNIGHT 2008/7/2 Rich Greenberg [EMAIL PROTECTED]: On: Tue, Jul 01, 2008 at 03:37:19PM -0500,Huegel, Thomas Wrote: } It all depends on what you want to do. } In some cases you may not want to wait forever for a file that may never arrive. } So you put the timer in. } If on the other hand the vm is totally driven by the arrival of a RDR file, then there would be no reason to have a timer value.

Re: Best method
If you have CA products available, check out KWAKEUP. It handles everything that WAKEUP does and does it better. For example, it gives you an option to put the information about the event causing the interrupt into REXX variables. There is no need to clear the stack of wakeup entries that did not cause the interrupt. It also does not have any necessity of having an artificial pre-midnight wakeup. An interval can be started on one day and not trigger the interrupt until some future date. It is WAKEUP compatible should you choose to go that route.

It handles everything that WAKEUP does and does it better. For example, it gives you an option to put the information about the event causing the interrupt into REXX variables. There is no need to clear the stack of wakeup entries that did not cause the interrupt. It also does not have any necessity of having an artificial pre-midnight wakeup. An interval can be started on one day and not trigger the interrupt until some future date. It is WAKEUP compatible should you choose to go that route.

Re: Best method
Jim Hughes asked: How would the STARMSG pipeline detect someone typing a message at the console and hitting the ENTER key? Would it require another concurrent pipe running? Concurrent, yes. For console input, I would simply fan-in a CONSOLE stage. You can even fan-in TCP connections, if you like. (trickier) What I typically do is attach the stages from within the gem (eg: MYTHING REXX). Something like ... /* REXX */ ... other stuff ... 'ADDPIPE (END !) STARMSG | FI: FANINANY | *.INPUT:' , 'CONSOLE ASYNC | SPEC /CONSOLE / | FI:' ... main body and the peekto/readto loop ... In this example, STARMSG prefixes each record with a message type, so I also prefix CONSOLE to each record of terminal input. -- R;

Re: Best method
It all depends on what you want to do. In some cases you may not want to wait forever for a file that may never arrive. So you put the timer in. If on the other hand the vm is totally driven by the arrival of a RDR file, then there would be no reason to have a timer value. -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] Behalf Of Schuh, Richard Sent: Tuesday, July 01, 2008 3:25 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Best method And if you leave that RDR file in the queue without holding it, it will give you another interrupt immediately.

Re: Best method
Lambasting another person's code when they were simply trying to help by sharing it didn't seem too relevant to the stated topic either, yet no one intervened THEN. This tells me we tolerate blatant rudeness, but not humor interjected to defuse tension caused by the rudeness. Guess it's all a matter of what our values are. The humor did get a bit over the top. But not nearly to the degree that good manners were disregarded.

Re: Best method
Thanks, Cal. Others have already suggested that. But it is really overkill. My entire EXEC consists of the following. And we have tested it thoroughly today, and it seems to do exactly what we want. The +2 is only because files will not be coming in very often, but when they do we want to process them quickly. The CHECK_OUT_FILE paragraph is only to retrieve the incoming rdr file number, file name, and file type for subsequent commands. The FTP2POW program does some manipulation and FTPs some files from VM to VSE.

If you just want to wait for RDR files, you don't need to wakeup each time to check. When a RDR file arrives you will wake up immediately. As long as you initialize WAKEUP properly and don't reset it, you should not even lose RDR file triggers (so WAKEUP will return immediately when there's another interrupt waiting). The mix of time and event is for when you *also* need to do things based on time schedule (eg close spool files every hour or so). -Rob (and I apologize for distracting the thread earlier)
Re: Best method
What if someone sends a vicious PROFILE EXEC to your server? you should check who sent something before blindly receiving it. Or check what was sent and only receive The do-loop checking rdr files can be made much simpler too: Check_Receive: 'EXECIO * CP (STEM AA. Q RDR * ALL NOHOLD' do i=2 to aa.0 parse var aa.i sender filenum if wordpos(sender,validsenders)=0 then 'CP CH R' filenum 'HOLD' else do 'EXEC RECEIVE 'EXEC FT22POW ... 'ERASE ... end end And, as Rob points out: this do-loop handles all RDR files, no need for the +2 in WAKEUP. 2008/7/2 Wakser, David [EMAIL PROTECTED]: Thanks, Cal. Others have already suggested that.
