New Features for Oracle Grid Infrastructure 18c

• gridSetup-based Management

  Gold Image-Based installation, using setup.exe, provides a centralized mechanism of installing and managing Oracle Grid Infrastructure. You can use gridSetup-based management to perform management tasks such as cloning, addNode operations, deleteNode operations, and downgrade using the gridSetup.bat command.

• NodeVIP-Less Cluster

  NodeVIP-Less Cluster simplifies cluster deployments and management by eliminating the need for additional IPs for each node in the cluster.

  Node VIP-Less cluster deployments are intended for use in volatile non-production environments, where ease of deployment outweighs the need for ease of failover management.

Desupported Features for Oracle Clusterware 18c

The following feature is desupported in this release:

• Desupport of crsuser Windows

  The crsuser utility and and the CRSToken method to change the Windows service user is desupported in Oracle Database 18c.

  In Oracle Grid Infrastructure releases before Release 12c (12.1), it was supported to use the crsuser utility with Oracle Real Application Clusters (Oracle RAC) to modify the database logon properties of the Oracle Database service from LocalSystem to a user ID.

  Oracle introduced the Oracle Home User system privileges role for the DB home in Oracle Grid Infrastructure 12c Release 1 (12.1). This role makes the need for the crsuser functionality unnecessary. The crsuser facility was also previously used to create user-defined CRS resources that ran as a Windows user other than LocalSystem. However, Oracle Grid Infrastructure 12c Release 1 (12.1) and later releases provide that same functionality with crsctl add wallet -type OSUSER The crsuser feature no longer works. It is no longer developed or supported.

  For more information about the crsctl add wallet -type OSUSER command, refer to Oracle Clusterware Administration and Deployment.
