I am having a challenge with CMOD and OAM.  We have a large number of reports in OAM DASD.  But most of them should have transitioned to OAM TAPE

We have worked on the ACS Code with IBM L2 SMS.  We have tried to set up reports to see if they actually transition.

I am looking for an easy way to diagnose the ACS routines to see how the transition process works

We thought when we set up CMOD with OAM the process was working.  Instead, some of the OAM Objects just keep growing on DASD and consuming everything they can.

I also need a refresher on the process used that tells OAM that the report should go to TAPE.

Our ACS routines are not complex.  but I think sometimes the logic flow in SMS for CMOD/OAM can get confusing for me

Thanks

z/OS Server / Moving CMOD to a new DB2 Region
« on: February 12, 2020, 03:51:57 PM »
Has anyone picked up and moved CMOD (all reports, everything) from one DB2 region to another?

Any considerations in doing that?

Thanks

z/OS Server / Any Migration guides from R9.5 to 10.1
« on: February 12, 2020, 11:50:22 AM »
We are going to upgrade from 9.5 to 10.1

But like the time we implemented 9.5 - as a system programmer - there does not seem to be any cohesive check list to lay out all the steps that are needed to do this upgrade.

Did anyone create a system programmer check list that could be shared?

Specifically, where does the zFS file get mounted?  and are any of the files in the filesystem mounted or just the main file?

Once the files are mounted and then STC JCL is updated with the new APF Authorized Load libs, and DB2 load libs, and the ARSBIN path, any other changes needed?

Do we need to run ARSDB prior to starting up CMOD?  Do all the scripts need to run or just certain ones prior to startup?

Inquiring minds want to know.

Thank you

z/OS Server / z/OS V2.3 and RACF Function Read Only Audit
« on: September 18, 2019, 01:32:25 PM »
In case you were not aware, with z/OS V2.3 and above, RACF now provides a function called Read Only Audit (ROAUDIT)

You can set this attribute on a userid and they will be able to do the following (Basically LOOK but don't touch)

A user who has the ROAUDIT attribute has the authority to list auditing information using the

   LISTDSD,
   RLIST,
   LISTUSER,
   LISTGRP,
   SETROPTS LIST,
   SEARCH commands
  as well as the IRRUT100 utility

Unlike users with the AUDITOR attribute, users with the ROAUDIT attribute are unable to specify logging options or to control logging to the SMF data set.


Thought this might be helpful to ADMINs for CMOD.

z/OS Server / CMOD 10.1 and 64Bi functions
« on: June 10, 2019, 02:09:20 PM »
I am currently 9.5 and looking to upgrade to 10.1 (or current version of 10)

I remember hearing that some things for migration to 10.1 would need to be done in 64bit mode.  That COBOL would not work - a rewrite in something like C/C++ or JAVA or other would need to be done

For those that have converted to 10.1 - was there anything that needed to be changed for 64Bit mod?  Or could you run with what you had under 9.5?

We are still a new shop to  CMOD and just looking for guidance.

z/OS Server / Request for Enhancemts for OAM
« on: November 09, 2018, 02:07:09 PM »
I have submitted several OAM and ISMF enhancements for OAM.  I find that there is some room for improvement.  If you are interested in seeing them, here are the links.  Not sure if you need access to www.ibm.com or other

http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=127007     Remove old members for SYS1.SAMPLIB for ACS code examples for CBR members

http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=126751     Provide a Wizard in ISMF Panels to create the necessary details to set up OAM

http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=126750     Enhance the HELP Panels in ISMF for OBJECTS

 http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=126749    Provide a function to interpret the OAM return codes   <---  my favorite one

There is no guarantee that IBM will implement any of them.  Hoping they will provide some of them so that setting up OAM for CMoD will be a happier experience.   I do have a few votes on these - so there is interest in these areas being enhanced.

the CMoD Admin is  trying to delete an Application Group that is empty.  Keeps getting RC08 from OAM with 40060303 which says

SREQ DELETE: Deletion is not allowed because the object is under retention-protection and the object’s retention date has not yet been reached.

Not sure why OAM is doing this?  Is there a process that is used to delete AG that are empty?

Thank you

z/OS Server / A Users Experience on using ARSMAINT -o on ODF tables
« on: July 10, 2018, 08:39:51 AM »
This is just a little overview of what I found out on how to purge data using ARSMAINT -o Function.  Always review with IBM before taking any actions.

We are new to CMoD.  We have been working with it for 6 months now and there are lots of things we are learning.  When it was set up - ARSODF_EXPIRE_DAYS was set to high.  This cause us to keep way too much data.  Before we finally did a purge on the DST Table, it contained over 100 million rows.  This required a drastic purge process.

After reading the manual on ARSMAINT - we thought we could use the following syntax    ARSMAINT -o -t YYYY-MM-DD

This did not work.  So we contacted Support who recommended the following process which did work.

1) Set ARSODF_EXPIRE_DAYS to how many days back you want to set the expiration date to.  For example, if you set it to 10 then the expire date will be today-10 as a starting point
2) Cycle SOCKS address space to pick up the new Expire Days
3)  Run ARSMAINT -o       no need to include the -t       the date is controlled by the EXPIRE DAYS parm

This was successful.   We could see that ARSMAINT was now purging about 4 million rows in 7 minutes

Some of the other actions we took to ensure that it ran quickly and without locking issues
1) Shutdown all CMOD tasks.  Leaving up only one SOCK address space where we would run ARSMAINT -o
2) Changed the  locking to Tablespace locking for the duration of the window to do the purges on the DST/DRT/PPT

Once we were done, we restore locking back to where it was before Tablespace locking

We also used this Query on each table to see if we really had purged rows.  Changing DST to DRT or PPT to get counts from those tables.

--  LIST ALL ENTRIES IN ODF TABLE BY DATE AND COUNT     
--                                                       
SELECT DATE(DST_PROCESS_DT), COUNT(*)                   
FROM ARSUSER.ARSDFDST                                   
WHERE DST_PROCESS_DT <= '2018-12-31-00.00.00.000000'     
GROUP BY DATE(DST_PROCESS_DT)                           
ORDER BY DATE(DST_PROCESS_DT)                           
WITH UR;                                                 


This is what we did to resolve our issue of a large number of rows in our ODF Tables for DST/DRT/PPT

Hope this helps someone else.

z/OS Server / Moving CACHE Files for CMOD to new Storage Array
« on: March 18, 2018, 08:56:47 PM »
I am looking to see if anyone has moved CACHE files with either TDMF or DFDSS.  If so, any requirements to do so?  Does CMOD need to be down with either?

We are required to move to a new storage array and I want to ensure nothing breaks with CMOD/CACHE

z/OS Server / Migration to DB1 V11 and CMoD 9.5.0
« on: February 19, 2018, 04:35:14 PM »
We are on CMoD V9.5.0 and DB2 V10.  We are planning to upgrade to DB2 V11.

Will CMoD V9.5.0 run with DB2 V11? Or do we need to upgrade CMoD to V10 when we go to DB2 V11?

I understand there will be additional requires like z/OS and COBOL if we have to upgrade CMoD to V10.

Thank you

z/OS Server / CMoD Administration Roles
« on: January 19, 2018, 07:51:45 AM »
We are a new CMoD Shop - Just 5 months with the product.  This is for the z/OS functions for CMoD

We are trying to determine the skill-sets for a CMOD ADMIN vs a CMOD System Admin (System programmer type)

So the typical CMOD ADMIN what are the skill sets needed for that

1) COBOL Coding - to create and maintain Report exits?
2) XML coding - to create massive updates using ARSXML?
3) Unix skills both batch and foreground - to run ARSMAINT
4) DB2 Skills (like SQL coding) so they can update the DB2 tables as appropriate - usually with assistance or list the contents of DB2 tables?

What are you using as the description and skill sets for your CMOD Administrators?


Anything else I might have missed?

z/OS Server / CMOD SOCKD Load Balancing in z/OS
« on: November 22, 2017, 01:38:49 PM »
cmod 9.5 on z/os v2.1

New to CMOD and architecture/configuration. 

I am wondering if there is a way to do the following

Using the following configuration:  3 LPARS in a SYSPLEX
Running SockD on each lpar as ARSSOCK1/ARSSOCK2/ARSSOCK3

Is there a way to do "load balancing" so that when USERA comes in - if ARSSOCK1 is not busy then it goes to ARSSOCK1
If USERB comes in And ARSSOCK1 is busy - magically goes to ARSSOCK3
and so on

Or if LPAR1 goes away for maintenance, the magic happens and connects users to active ARSSOCKx tasks?

Any way to do this in z/OS with WLM or VTAM EE/Generic Resources etc?

I would like to give my users a generic VIPA name like CMODPRD and then let magic happen as to which ARSSOCKD it comes in through

We have  DB2 Sharing environment on only one DB2 table (so far).  So the less information my users need, for example, Set up your Server to LPAR1 or LPAR2 or LPAR3 with this Port number, the better.

Thank you

Lizette
