Known issues when running DB2 Version 9 on Solaris: Solaris 10 Performance degradation with Solaris 10 and Solaris 10 Update 1 due to significant increase of CPU User Time (up to 30%). The problem is a result of a bug in a Page Coloring mechanism, identified in SUN's CR 6337073. This bug was fixed in the kernel patch 118833-02, though it is recommended to install Solaris 10 Update 2, which comes with kernel patch 118833-17. Another way of fixing the problem is setting consistent_coloring = 2 in /etc/system. Known issues when running DB2® Universal Database (DB2 UDB) Version 8 on Solaris: Solaris 8 DB2 UDB traps on Solaris 8 when using FASTGROUPS registry variable. The DB2 UDB instance traps in a dlopen(NULL, RTLD_NOW) call. The problem is related to a SUN linker bug and was fixed in the patch 109147-40.
