IPCC High Availability

When you install two IPCC servers the following considerations hold true:

 a. The first server you activate (CRS Engine and/or Datastore services) will become the active CRS box.

 b. The second server you activate (CRS Engine) will become the standby box for the active CRS engine.

 c. The second server you activate (Datastore engine) will become the standby box for the active Datastore engine. (Agent, Historical etc).

 d. When you create a jtapi user in the active box (first server in your cluster), the user name that is created in Callmanager is “jtapi_1” the one signifying that its the jtapi user for the first CRS server. When you install the second CRS server, it will create another jtapi user named “jtapi_2”.

 e. The second server that you install will use the administrator username / password of the first box during the initial server setup. You should not use Administrator / ciscocisco password.

 f. If the active box has a jtapi group with 20 CTI ports ranging from 3201 to 3220, when you initialize the standby box, it will automatically create 20 more CTI ports from 3221 to 3240. 

 g. JTAPI groups that are created in IPCC coressponds to CTI ports created in Callmanager. The ports in Callmanager that belong to the active CRS box will have a description (if you leave it at defaults) as JTAPI Group #0 – 1. The ports that belong to the standby CRS box will have a description JTAPI Group #0 – 2
