Important Notes About the High Availability Login Profiles

The High Availability login profiles only apply to Cisco Unified Presence Release 8.5 or higher 8.x releases, and Cisco Unified Personal Communicator Release 8.5 or higher 8.x releases.

You can use the High Availability login profile tables in this section to configure the upper and lower client re-login values for your subcluster. You configure the upper and lower client login values by selecting Cisco Unified Presence Administration > System > Service Parameters, and selecting Cisco UP Server Recovery Manager from the Service menu.

By configuring the upper and lower client re-login limits on your subcluster based on the tables we provide here, you can avoid performance issues and high CPU spikes in your deployment.

We provide a High Availability login profile for each Cisco Unified Presence server memory size (2, 4 or 6 GB), and for each High Availability deployment type, active/active or active/standby.

The High Availability login profile tables are calculated based on the following inputs:

The Users Moved Per Iteration service parameter. This parameter determines the number of users moved per iteration during a failover or a fallback operation. We provide a recommended value for the Users Moved Per Iteration service parameter for each High Availability login profile table.

The total number of users in the subcluster for Active/Standby deployments, or the node with highest number of users for Active/Active deployments.

You must configure the upper and lower client re-login limit values, and the Users Moved Per Iteration service parameter on both nodes in a subcluster. You must manually configure all these values on both nodes in the subcluster.

The upper and lower client re-login limit values must be the same on each node in the subcluster.

If you rebalance your users, you must reconfigure the upper and lower client re-login limit values based on the High Availability login profile tables.

Configuring the Advanced Service Parameters for the Server Recovery Manager

Using the High Availability Login Profile Tables

Use the High Availability login profile tables to retrieve the following values:

Client Re-Login Lower Limit service parameter value

Client Re-Login Upper Limit service parameter value.

Users Moved Per Iteration service parameter value.

Procedure


Step 1 Select a profile table based on your memory size, and your High Availability deployment type.

Step 2 In the profile table, select the number of users in your deployment (round up to the nearest value). If you have an active/standby deployment, use the node with the highest number of users.

Step 3 Based on the Number of Users value for your subcluster, retrieve the corresponding lower and upper retry limits in the profile table.

Step 4 Configure the lower and upper retry limits on Cisco Unified Presence by selecting Cisco Unified Presence Administration > System > Service Parameters, and selecting Cisco UP Server Recovery Manager from the Service menu.

Step 5 Retrieve the corresponding Users Moved Per Iteration service parameter value for your High Availability login profile table.

Step 6 Configure the Users Moved Per Iteration value on Cisco Unified Presence by selecting Cisco Unified Presence Administration > System > Service Parameters, and selecting Cisco UP Server Recovery Manager from the Service menu.

Example 1: 6GB Active/Standby Standard Deployment

You have 3,000 users in your subcluster, with 2000 users on one node, and 1000 users on the second node. For active/standby deployments, we recommend you use the node with the highest number of users, in this case the node with 2000 users. Using Table 16-12, you retrieve these lower and upper retry values:

Number of Users
Lower Retry Limit
Upper Retry Limit

2000

40

107



Note The upper retry limit is the approximate time (seconds) it takes for all clients to login to their backup node after a failover occurs.


You also configure the corresponding Users Moved per Iteration service parameter value for Table 16-12 which is 50.

Example 2: 4GB Active/Active IM-Only Deployment

You have 6800 users on the first node in your subcluster in an IM-only deployment. We recommend that you round up to the nearest value, so using Table 16-4 you retrieve the lower and upper retry value based on a number of users value of 7000:

Number of Users
Lower Retry Limit
Upper Retry Limit

7000

280

1447


You also configure the corresponding Users Moved per Iteration service parameter value for Table 16-4 which is 25.
