Hi Shelia,
Is there a z/OS 3.1 SCLM Project involving DGA (Connect:Direct)?

Thanks for reaching out.  But I have z/os 2.4 lpar and when create a new 
dataset I don't get the sclm message.
Then I have a z/os 3.1 lpar and when we create a new dataset, I get the sclm 
message.

I can't figure out where the difference is?  I have looked at the 
SCLM_WARNING_LEVEL default is warn in all z/os 2.4,2.5 and 3.1. I can update 
the ispcfigu to turn warn to none.
But it is not that way on z/os 2.4.

Hopefully, this makes sense.

Thanks for your help again.

Hi Shelia,
I think that you can change this by modifying (or deleting) the ISPF Stats for 
the member (or zapping Byte 3).
Please see:
ISPF statistics entry in a PDS directory

z/OS ISPF Dialog Developer's Guide and Reference
SC19-3619-00

A valid ISPF directory can consist of fifteen halfwords of user data with bytes 
28-30 blank, or twenty half words of user data with bit 3 of byte 3 set on. 
Shown here is the format of the information that ISPF writes to the PDS 
directory to maintain statistics for a member. If you suspect the statistics 
data has been corrupted, you can compare the existing entry against these 
formats to help in problem determination.

*Byte*
     *Description and Format*
1
     Version number, in hexadecimal format. Value is betweenX'01'andX'99'.
2
     Modification level, in hexadecimal format. Value is
     betweenX'00'andX'99'.
3
     Flags:

     Bit 1
         SCLM indicator. SCLM uses this to determine whether the member
         and any related SCLM information are still in sync.

           * ON means the member was last edited by SCLM, the Software
             Configuration and Library Manager.
           * OFF means the member was somehow processed outside SCLM.

One way to do this is to start 3.5 and change the SCLM setting to Non-SCLM.

Regards,
David

Happens on some datasets and not others.

Can anyone tell me how to turn this off or how to fix this?

Thanks
