ARSUPERC
« on: January 30, 2019, 05:06:19 AM »
Hi, is it someone who has or has experience of the following message and above all knows what the return code and resoncode means ?

ARSUPERC.ARSZUXF ACEE Locate failed for UID Retcode:00001 Reason:00005

we get this message in connection with a user trying to pick up a folder via the OD32 Client and the answer back that she / he is not authorized, after the user has logged off and logged on again it works OK?!
And Yes we have a customized exit (ARSUPREC) but it have work for years…..

Regards
Hans-Erik

Hello Hans-Erik -

What is the BPXF024I message for this?

If this is an old system do you have the service for PK94194 installed?

Have you recompiled/relinked if this is a new system?

I think this will resolve the problem.

I believe your ACEEs get cached by the COFVLFxx PARMLIB member:

CLASS  NAME(IRRACEE)      /* RACF saved ACEEs        */
       EMAJ(ACEE)         /* Major name = ACEE       */


This is managed by the least-recently-used algorithm.

So if the entry in there is getting old and cast out, but logging back in refreshes the entry, that would explain the behavior.

Please review this section of the pub on the MAXVIRT parameter:

https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.ieae200/cofvlf.htm

Per here, the default is 4096 4K blocks or 16 megabytes:

https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.ieae200/ieae200123.htm

16 meg isn't much these days.

You could probably double that easily.

CLASS  NAME(IRRACEE)      /* RACF saved ACEEs        */
       EMAJ(ACEE)         /* Major name = ACEE       */
       MAXVIRT(8192)      /* 4K blocks, def 4096     */

Hi Ed !

Thanks for your answer, I will try your suggestions A.S.A.P., but I have to talk with my collegue about the COLFVLM parameters Before I do the Changes.

Our system is running on V9R5M0 !

Yes, I have recompiled/relinked the arsusecc, arsusecx, arsusecz,  arsuprec when I upgraded to that level.

Hans-Erik -

While you're looking at your COFVLFxx make sure it has, at a minimum, the following entries:

Quote
CLASS NAME(CSVLLA)        /* Class name for Library Lookaside @P2C*/
      EMAJ(LLA)           /* Major name for Library Lookaside @P2C*/
CLASS  NAME(IRRSMAP)      /* OpenMVS_RACF SMAP Table */               
       EMAJ(SMAP)         /* Major name = SMAP       */               
CLASS  NAME(IRRGMAP)      /* OpenMVS_RACF GMAP Table */               
       EMAJ(GMAP)         /* Major name = GMAP       */               
CLASS  NAME(IRRUMAP)      /* OpenMVS_RACF UMAP Table */               
       EMAJ(UMAP)         /* Major name = UMAP       */               
CLASS  NAME(IRRGTS)       /* RACF GTS Table          */               
       EMAJ(GTS)          /* Major name = GTS        */               
CLASS  NAME(IRRACEE)      /* RACF saved ACEEs        */               
       EMAJ(ACEE)         /* Major name = ACEE       */   

It's likely it has much more than that, but at a minimum it should have all of those entries.

HI Ed, thank you once again for your quick response and suggestion for action, my colleague who is responsible for z / os increased the value dynamically yesterday and after restarting ARSSOCKD I have not seen the error message again, hopefully the error is fixed.
