Class values

A class value indicates an alternative way to release a held SYSMOD. These are the values currently used by IBM®:
Class
Explanation
ERREL
The SYSMOD is held for an error reason ID but should be installed anyway. IBM has determined that the problem the SYSMOD resolves is significantly more critical than the error reflected by the holding APAR.
HIPER
The SYSMOD is held with a hold class of HIPER (High Impact)
PE
The SYSMOD is held with a hold class of "PTF in Error".
UCLREL
UCLIN needed for the SYSMOD has been handled by IBM and no longer requires your attention.
YR2000
Identifies PTFs that provide Year 2000 function, or fix a Year 2000-related problem.
