Error description

  • The db2prereqcheck utility was enhanced to check for libpam.so
    in DB2 version 9.7 FP6 via APAR IC78338 and the validation is
    done by looking up "libpam.so" (either a file or a symbolic
    link) on the system. The original approach was to look up the
    file libpam.so.0 on system, however this would not work on
    systems with updated PAM module.  PAM module could be updated
    from time to time and if we hard-coded db2prereqcheck to check
    for libpam.so.0, then the check would fail on newer system where
    the module might have updated to upper version like libpam.so.1.
    
    In most case a symbolic link of libpam.so would be created to
    point to latest version of libpam.so.x, hence have
    db2prereqcheck to look for libpam.so (either a file or a symbol
    link). This approach  was to avoid any further issue with PAM
    module upgrade on affected platform. However this may not work
    on older system which has libpam.so.0 only.
    

Local fix

  • Create a symbolic link named libpam.so that points to
    libpam.so.0:
    
    ln -s libpam.so.0 libpam.so
