Oracle Automatic Storage Management (Oracle ASM) on top of files hosted on shared file systems and used as ASM disks remains. In Oracle Grid Infrastructure 12c Release 2 (12.2), Oracle announced that it would no longer support the placement of the Oracle Grid Infrastructure Oracle Cluster Registry (OCR) and voting files directly on a shared file system. This desupport is now rescind‐ ed. Starting with Oracle Grid Infrastructure 19c (19.3), with Oracle Standalone Clus‐ ters, you can again place OCR and voting disk files directly on shared file systems. Related Topics Using a Cluster File System for Oracle Clusterware Files Optional Install for the Grid Infrastructure Management Repository Starting with Oracle Grid Infrastructure 19c, the Grid Infrastructure Management Repo‐ sitory (GIMR) is optional for new installations of Oracle Standalone Cluster. Oracle Do‐ main Services Clusters still require the installation of a GIMR as a service component. The data contained in the GIMR is the basis for preventative diagnostics based on ap‐ plied Machine Learning and can help to increase the availability of Oracle Real Appli‐ cation Clusters (Oracle RAC) databases. Having an optional installation for the GIMR allows for more flexible storage space management and faster deployment, especially during the installation of test and development systems. Related Topics About the Grid Infrastructure Management Repository Deprecated Features Review features that are deprecated starting with Oracle Database 19c. For more information about deprecated features, parameters, and views, refer to Ora‐ cle Database Upgrade Guide Init.ora Parameter CLUSTER_DATABASE_INSTANCES is Deprecated The Oracle Database initialization parameter CLUSTER_DATABASE_INSTANCES is deprecated in Oracle Database 19c (19.1) The init.ora parameter CLUSTER_DATABASE_INSTANCES specifies the number of configured Oracle Real Application Clusters (Oracle RAC) instances. Starting with Oracle Database 19c and later releases, the number of configurable Oracle RAC instances is derived automatically from the Oracle Clusterware resource defini‐ tions. There is no replacement for this parameter, because there is no longer a reason to have this parameter.
