Desupported Features for Oracle Database 18c

Desupported feature for Oracle Database 18c.

The following feature is desupported in this release:

• Oracle Administration Assistant for Windows

  The Oracle Administration Assistant tool for Windows is desupported in Oracle Database 18c.

• Deprecation of crsuserThe 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.
