22 CHAPTER 2: INSTALLATION
For new installations, the policy is set to Primary by default.
To configure the primary policy:
1Edit this file on the Primary Server:
/usr/app/app.dir/config.app
2Find the line that begins with:
IM_policy=
3Modify the line, if necessary, so that it reads:
IM_policy=primary
4Restart Call Builder on the Primary Server.
When Call Builder restarts on the Primary Server, it is in the standby state.
After 5 minutes, it switches to active state.
Balanced Intelligent
Mirroring Policy
This policy specifies that when one of the servers enters the active state, it
stays in that state until it fails or someone shuts it down.
To configure the balanced policy:
1Edit this file on the Primary Server:
/usr/app/app.dir/config.app
2Find the line that begins with:
IM_policy=
3Modify the line, if necessary, so that it reads:
IM_policy=balanced
4Restart Call Builder on the Primary Server.
Switching Between
Active and Standby
States
The Primary Server can enter the standby state in either of these two
ways:
■When the Primary Server starts, the Secondary Server is in the active
state. Therefore, the Primary Server enters the standby state.
OR
■Someone issues a command to force the Primary Server into the
standby state.
