Oracle 10g Failover Instance
Oracle 10g Failover Instance
Instance name (SID) of oracle instance
Oracle SID
Oracle user name. This is the user name of the Oracle
user which the Oracle AS instance runs as.
Oracle User Name
This is the Oracle (application, not user) home directory.
This is configured when you install Oracle.
Oracle Home Directory
This is the Oracle installation type.
Only "10g" and "10g-ias" are supported, and 10g-ias is
untested.
Oracle Installation Type
Virtual Hostname matching the installation hostname of
Oracle 10g. Note that during the start/stop of an oracledb
resource, your hostname will temporarily be changed to
this hostname. As such, it is recommended that oracledb
resources be instanced as part of an exclusive service only.
