Oracle Database 12c (12.1 and 12.2) How does one modify the database resource parameter AUTO_START

edited Mar 16, 2018 5:04AM in Database Administration (MOSC) 3 commentsAnswered

In Oracle documentation for 12cR1 and 12cR2,  it states that one does not use crsctl modify resource... for any resource that begins with "ora".   There is the "-unsupported" switch that allows the DBA to override the restriction to set the resource attributes.   In the 12cR2 administrator documentation is is explicit about not using crsctl to modiry "ora..." resource attributes.   The DBA must use srvctl to modify database parameters.

Here is the problem we have had since Oracle 11gR2.  The database resource attribute, "AUTO_START" is set to "restore"  which when we restart host servers after patching does not bring the RAC databases back up and online.  So we have to set the attribute "AUTO_START" = "always" to get the databases online in 11g and 12c as follows

Howdy, Stranger!
