BigFix Server on Linux (v9.5.14+ and v10.0.0+) supports IBM DB2 up to 11.5 GA version. It has not yet been certified on IBM DB2 11.5.4 (DB2 Version 11.5 Mod 4 Fix Pack 0) version.
A problem has been reported that prevents BigFix from functioning when running on IBM DB2 11.5.4 version.
While BigFix team works to guarantee compatibility with the newest IBM DB2 version, all BigFix users are strongly advised not to upgrade their IBM DB2 to version 11.5.4, for the time being.
Additional information on this matter will be communicated as soon as it is available.
