how to plan and use sysrexx?

Victor Niu · Posted: Fri Jun 11, 2010 9:23 am

please can anyone tell me something about plan and use system rexx?

I know the address space 'AXR' is for sysrexx and already active in SDSF

NP JOBNAME StepName ProcStep JobID Owner C Pos DP Real Paging SIO
AXR AXR IEFPROC NS C1 416 0.00 0.00

but when I exex a short sysrexx progam,an error occured...

program is here:

/* REXX */
XXX = AXRCMD('D IPLINFO','LIST.',10);
DO I = 1 TO LIST.0
SAY LIST.I
END

error is here:

17 +++ XXX = AXRCMD('D IPLINFO','LIST.',10)
IRX0043I Error running SYSREXX, line 17: Routine not found
***

I'm afraid there still some components should be configured for this AS.thanks.

Hello,

If you intended to communicate something to the forum with your most recent reply - you missed. . . Someone may understand your most recent post, but i surely do not. . .

For someone to help, you need to show more detail. Where is this being run? Online or in a batch job? If batch, show the jcl.

thanks for ur consideration...

SYSTEM REXX is a new component for z/os v1.9 and above.

Starting SYSREXX Requires
– Ability to read SYS1.PARMLIB
– Parmlib member CTIAXR00
– Ability to read SYS1.SAXREXEC

The role of SYSREXX in “New Face of z/OS” is to provide an infrastructure through which REXX execs may be run outside the normal TSO/E or Batch environments, using a simple programming interface. This enables the leveraging of base operating system components by new style applications that will, over time, lead to simplified interaction and more intuitive system management capabilities on z/OS.
The ability to initiate REXX execs directly from an operator console has been long overdue on z/OS and is a drag along benefit of this initiative.
The possibilities for exploiting existing REXX code through the use of SYSREXX are vast, whether to provide operator assists or to provide routines that can be leveraged by new strategic initiatives.

Hello,

If you run outside tso/ispf i suspect there will be problems trying to run anything that requires either or both of these . . .

The problem posted (routine not found) appears to be due to one or more "missing" libraries.

can't find the corresponding library...

Hello,

Have you asked the system support people?

Will this command find the routine if you run it in your online tso session? It might not work properly, but if it runs and fails, you know it is "there".

thanks,dick

resolved this problem by myself.

the system rexx pgm can be executed outside of conventional tso/e and batch environments,such as from operational console.

The default command prefix is 'REXX&SYSCLONE',it can be customized in SYS1.PARMLIB(AXR00). and the pgm should be copied to sysrexx library SYS1.SAXREXEC.

my program name is 'HELLO' and sysclone name is'1A',so I can run this command 'REXX1A HELLO' in console and sdsf. the result is:

RESPONSE=ADCD
AXR0500I AXREXX OUTPUT DISPLAY 397
EXECNAME=HELLO REQTOKEN=0000400000000000C61F27CD66292001
IEE254I 12.57.05 IPLINFO DISPLAY 396

@Dick Hi; System Rexx has limited TSO functionality but enough to make it useful. We use it on our SYSPROG images to start and stop the systems. They are test systems and we could not justify the expense of installing automations software . Also many of our ops staff do not have access to TSO this gives us the opportunity to give them access to more information and also to tailor the information.
Finally a question What is a console commander ? it is a term I have not come across before and when I look in google it is not that helpful

Hello,

Sorry 'bout that. . . my bad. . .

"Console commander" is a slang term for Computer Operators who man the "system console" and are not involved with scheduling, job setup, peripherals (tape, cart, paper, etc), etc.

Multiple people may have security permissions to issue console commands, but these people (the console commanders) spend their entire shift working system consoles.

Not everywhere has this particular setup, but one of my most recent clients has 9 "really big" mainframes, runs over 30 production lpars and as many as 400 cics regions. There are multiple operators to monitor and respond to console activity 24x7.

System rexx has many restrictions; but you can call system rexx from an authorized program, which I think is a failing of other alternatives.

Though, I have never used it.

hello nevilh

how to understand the statements:

"There are two different execution environments that are supported:

TSO=NO |TSO=YES"

and specified this parameter in which member?

do u know how to invoke the system rexx by jcl?

nevilh · Active User Joined: 01 Sep 2006 Posts: 262

If we use system rexx in batch we invoke it from home written assembler programs (from the documentation I am not sure if it can be directly invoked) . Though it can be invoked from either SDSF batch or any program that can issue commands. The TSO=xx can be defined on the AXREXX macro . If TSO=NO is specified the task will run in a shared address space and cannot issue certain host commands. If TSO=YES is specified the task will run in an isolated isingle address space

Victor Niu · Posted: Thu Jun 17, 2010 1:25 pm

thanks,nevilh,dick and Pedro

in this case，system rexx is no use for task.

my requirement is that a simply pgm can write some self-defined messages which are not highlight to syslog and master console.

Then some concernful jobs can invoke this pgm to give alarms once abends occured.

at beginning,I hope the system rexx can satisfy this requirement and then no need assembler pgm and netview rexx developing.

Victor Niu · Posted: Thu Jun 17, 2010 2:03 pm

'WTO' and 'WTOR' can write msg to syslog,they are netview commands.

PeterHolland · Posted: Thu Jun 17, 2010 2:32 pm

Victor Niu · Posted: Thu Jun 17, 2010 9:00 pm

Hi,PeterHolland

I'm afraid you are misunderstanding my requirements.

I need the pgm to monitor the concernful jobs.

if the jobs abend,the pgm will write a self-defined msg to syslog.

Pedro · Posted: Thu Jun 17, 2010 11:25 pm

Can you elaborate on what you mean by 'monitor'?

And what problem prevents you from using system rexx? I thought you would issue a "D A,L" command and then to examine the results to make sure that your STC's are listed there.

An alternate approach is to use SDSF DA command and make sure your STCs are there.

Victor Niu · Posted: Fri Jun 18, 2010 7:12 am

Hello Pedro

The jobs I have to monitor run very frequently,about 10 times a day.It is ok to check the jobs' status by SDSF,but laborious.

What I need is an automatic process which can monitor the jobs and will be triggered if error occured.

after self-defined msg written to syslog, netview MPF will trap this msg,like PeterHolland says.
