To provide customers more frequent access to recommended and well-tested collections of patches, Oracle is pleased to introduce Monthly Recommended Patches (MRPs) starting Nov 2022. MRPs are supported only on the Linux x86-64 platform. Non-Linux x86-64 customers should continue to apply patches as documented in "Oracle Database 19c Important Recommended One-off Patches (<Note 555.1>)
Starting with Oracle Database 19c RU19.17 (mid-October 2022), MRPs will be delivered for each RU in the 6 months following each RU's release. These will include the fixes documented in "Oracle Database Important Recommended Patches" (<Note 555.1>), RU regression fixes plus the prior MRPs for the RU.
While RUs will continue to be available on all supported platforms, MRPs will only be offered on Linux X86-64 platforms. Customers can continue to request one-off patches on all supported platforms. If a particular month does not have new recommended fixes for an RU, then no MRP will be released, and an annotation will be added in the relevant MOS notes to avoid confusion. Merge patches will be provided if there are conflicts between one-off patches and the latest MRP for an RU.
Starting in February 2023, MRPs are delivered separately for Single Instance DB (SIDB) installs and RAC installs. The 19c DB MRPs, which include DB/ASM fixes cumulatively, are to be applied to SIDB installs. Whereas, the 19c GI MRPs (system patches), which include DB and OCW/ACFS/ASM fixes cumulatively, are to be applied to RAC installs that have DB and GI homes.
The latest MRP for 19c can be downloaded from section 6.2 "Database 19" of MOS (<Note 888.1>).
