Note the following with regard to Oracle Database Upgrade Guide (E86577):
In the chapter titled "Deprecated and Desupported Features for Oracle Database 12c", should include the following desupport notice:
In Oracle Grid Infrastructure releases before Release 12c (12.1), it was supported to use the
crsuserutility with Oracle Real Application Clusters (Oracle RAC) to modify the database logon properties of the Oracle Database service from
LocalSystemto 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
crsuserfunctionality unnecessary. The
crsuserfacility 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
crsuserfeature no longer works. It is no longer developed or supported.
For more information about the
crsctl add wallet -type OSUSERcommand, refer to Oracle Clusterware Administration and Deployment.
