According to the Siteminder/SSO policy server R12.8 Platform Support Matrix, we have support SSO r12.8.x on Oracle RAC 12c (ONLY) and not greater versions like RAC 12.2 or 12c R2.
DD support is there only for Oracle RDBMS 12C R2 and NOT for Oracle RAC 12c R2 or 12.2. Could you please certify the data driver to support Oracle RAC 12.2 as well.
The Oracle Wire Protocol Driver versions on SSO R12.8.x.
SSO r12.8.1: 08.01.0081 (B0125, U0091)
SSO r12.8.2: 08.01.0081 (B0125, U0091)
As per Progress, the Data Driver vendor mentioned that they certified Oracle 12c R2 (12.2) with driver version 008.01.2067 (B0252, U0168) . Refer the link for more details. https://www.progress.com/odbc/release-history/oracle-database-odbc
Can the Siteminder Policy server 12.8.x certified with the supported data driver to connect Oracle RAC 12.2 with the driver version 008.01.2067 (B0252, U0168). looks like a minor upgrade but it supports great.
