Oracle Fail Safe - Version 3.0 and later
Generic Windows


The purpose of this document is to demonstrate how to configure a database resource with Oracle Fail Safe such that it can use logon credentials other than 'local system account' or the Oracle Fail Safe domain account.
Typically when running a Windows database service under the control of Oracle Fail Safe Server the relevant services are typically configured with the following credentials:

ServiceLog On As
Oracle Failsafe Service <domain>\<FS admin>
OracleService<SID> Local System account
Oracle<OHname>TNSListener<> Local System account

Changing the database & listener service to use the same credentials as the OracleMSCS service is easily achieved and requires no other changes.
However, when changing the credentials to a 3rd user additional steps need to be taken to allow this to work.
Having the database & listener services using a different account than the OracleMSCS service or Local System requires a change of the database authentication method from 'OS authenticated' to 'SYS account' .
