  • 1.  Message CKF0002. What is a library type of RCPLIB?

    Posted Tue December 02, 2025 09:58 AM

    Hello,

    Our CKFREEZE logs contain multiple CKF0002 messages. For example, "CKF0002 04 LOCATE return code  8 on RCPLIB data set SYS1.COBOL.SIGYCOMP".

    The messages don't cause a problem, but we would like to know what is an RCPLIB type of data set. 

    Thank you, Bill

    Hello Bill,

    RCPLIB refers to RACF Controlled Program List, and CKFCOLL tries to locate datasets that are referenced as members in profiles in the RACF PROGRAM class.


    You can use zSecure to find where these are defined, e.g.:

    RA.R -> Class name PROGRAM -> also select "Profile fields" and when the resource selection panel is shown enter -> Member key  . . . . SYS1.COBOL.SIGYCOMP

    to find which profile, but I am guessing these are probably all referenced as members under the ** profile.


    You could clean these definitions up, or just choose to ignore the warning messages.

    Regards, Mike

    Hello,

    Thank you for contacting zSecure Support.
    The RCPLIB means RACF® Controlled Program LIBrary. zSecure Collect tries to get library information defined by the RACF PROGRAM class profile (in cases where the RACF® program control is activated (SETROPTS WHEN(PROGRAM))) and the data set location service indicated an error (probably because the data set is missing or not cataloged).

       Best regards,
        Eugene
