I installed the Oracle 220.127.116.11 patch on a Solaris 9 64-bit server. Fortunately before I installed the patch I reviewed “Oracle9i Release 2 (9.2) Support Status and Alerts” on Metalink. For isssues specific to the 18.104.22.168 patch read Metalink Note 388281.1. There are known issues (Bug 4547809) on Solaris 64-bit, as well as other OS platforms.
The primary issue with my platform is outlined in Metalink Note 390993.1 regarding a missing owapatch.sql file. The note outlines a workaround which is to download and copy the owapatch.sql file into $ORACLE_HOME/rdbms/admin prior to running catpatch.sql.
It appears the 22.214.171.124 patch already contains the security patches in CPUJul2006 and CPUOct2006.
It appears Oracle updated the CPUOct2006 advisory on October 31 and there are vulnerabilities in the 126.96.36.199 patch. You can find the details at the Integrigy Oracle Security Blog.
