 Posted: Mon Sep 15, 2008 10:52 am Post subject: Determine Current Setting of OPTCD. |
 |
|
How can I obtain the current setting of the Optional Services Code (OPTCD) for a given dataset?
I've checked the Data Set Utility panel (3.2) and performed a LISTCAT ENTRIES(dsname) ALL, and neither appears to give the OPTCD value.
Background: We have a utility (USCCOPY) that does not support certain OPTCD values. 'Something' is changing the OPTCD value of a dataset we have, to a value that is unsupported by the utility.

Take a look HERE to read about OPTCD values.

I don't usually think of a dataset having an assigned OPTCD. It's more of an option you choose when you OPEN a file for processing.
What do you think is the OPTCD causing the problem?

The OPTCD was 'C' (chained scheduling).
The OPTCD is now 'Z' (search-direct for sequential datasets).
USCCOPY does not support OPTCT = Z. |

| It would require some code to locate and interpret the DS1OPTCD byte in the format-1 DSCB for the dataset... |

1. Thank you expat, for the link to the MVS JCL Reference. I found the section that listed and defined OPTCD values. That was helpful.
2. Thank you jgr for information on how to pull the OPTCD value for a given dataset by looking at the internals of the dataset. I've just been given access to an online utility (Startools) that will display the current OPTCD value for a dataset. So, I'm all set on that front.
 If by chance, anyone has any thoughts about what process would reset OPTCD values, please feel free to post.
Thank you again,
Dave |

Rather than resetting the OPTCD, you should be able to circumvent your problem by adding DCB=OPTCD=C to the applicable USCCOPY DD statement. This should have the effect of overriding the OPTCD in the dataset's DSCB.
If you still in fact do need to reset the DSCB's OPTCD, this can be done via AMASPZAP (error prone and dangerous), or custom code (cleaner and safer). |

I added DCB=OPTCD=C to the input dataset, as shown below:
| Code: |
//S17GEN EXEC GENERP
//GENR10.SYSUT12 DD DSN=&QUAL1..FOCUS.HPARDIST,
// DISP=SHR,
// DCB=OPTCD=C
//GENR10.SYSUT12O DD DSN=&QUAL1..TEST.HPA150.TEST(+1),
// DISP=(NEW,CATLG,DELETE),
// SPACE=(CYL,(50,10),,CONTIG),
// DCB=(RECFM=F,LRECL=4096,BLKSIZE=4096)
//GENR10.SYSUT20 DD *
ONLY ONE RECORD
/*
//GENR10.SYSUT20O DD SYSOUT=*
|
Unfortunately, I sill obtain the following error message from USCCOPY:
| Code: |
***********************************************************************

***********************************************************************

I appreciate all advice, comments, and suggestions received so far.
If anyone has any additional comments, that would be great.
The fundamental issue is, I think, that USCCOPY is sensitive to a OPTCD of 'Z'.
I don't know what at our shop is setting the OPTCD to Z for this one dataset.
If there is a workaround, were I could get USCCOPY to work, that would be fine. |
