For applying single patches or Release Updates / Patch Set Updates to Grid Infrastructure or Database homes follow standard procedures documented by Oracle.
Note: While GI cluster is in rolling patching mode, do not reboot any nodes and do not stop FlashGrid services. Updating OS or FlashGrid software simultaneously with applying Grid Infrastructure patches in rolling fashion is not recommended.
Note: Before applying the latest Release Update from Oracle, we recommend to request confirmation from FlashGrid support . FlashGrid performs validation of every Release Update to minimize risk of compatibility or reliability issues. Typical time to complete the validation is 3 weeks after the Release Update is publicly available.
