High Availability Login Profiles

Important Notes About High Availability Login Profiles• You can use the High Availability login profile tables in this section to configure the upper and lowerclient re-login values for your presence redundancy group. You configure the upper and lower clientlogin values by choosing Cisco Unified CM IM and Presence Administration > System > ServiceParameters, and choosing Cisco Server Recovery Manager from the Service menu.

• By configuring the upper and lower client re-login limits on your presence redundancy group based onthe 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 IM and Presence Service node memory size, andfor each High Availability deployment type, active/active or active/standby.

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

• The lower client re-login limit is based on the Server RecoveryManager service parameter "CriticalService Down Delay", for which the default is 90 seconds. If the Critical Service Down Delay ischanged then the lower limit must also change.

• The total number of users in the presence redundancy group for Active/Standby deployments, orthe node with highest number of users for Active/Active deployments.

High Availability Client Login Profiles1

• Youmust configure the upper and lower client re-login limit values on both nodes in a presence redundancygroup. You must manually configure all these values on both nodes in the presence redundancy group.

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

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

Use High Availability Login Profile TablesUse 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.

Procedure

Step 1 Choose a profile table based on your virtual hardware configuration, and your High Availability deploymenttype.

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

Step 3 Based on the Number of Users value for your presence redundancy group, retrieve the corresponding lowerand upper retry limits in the profile table.

Step 4 Configure the lower and upper retry limits on IM and Presence Service by choosing Cisco Unified CM IMand Presence Administration > System > Service Parameters, and choosing Cisco Server RecoveryManager from the Service menu.

Step 5 Check the Critical Service Down Delay value by choosing Cisco Unified CM IM and PresenceAdministration > System > Service Parameters and choosing Cisco Server Recovery Manager from theServiceMenu. The default value is 90 seconds. The lower retry limit should be set to this value.

Example High Availability Login Configurations

Example 1: 15000 Users Full UC Profile - IM only active/active deployment

You have 3000 users in your presence redundancy group, with 2000 users on one node, and 1000 users onthe second node. For an unbalanced active/active deployment, Cisco recommends you use the node with thehighest number of users, in this case the node with 2000 users. Using the 15000 users full US (4 vCPU 8GB)active/active profile, you retrieve these lower and upper retry values:

Upper Retry LimitLower Retry LimitExpected Number of Active Users

3121202000


High Availability Client Login ProfilesUse High Availability Login Profile Tables

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

Note

The lower limit of 120 assumes the Critical Service Down Delay service parameter is set to 120.Note

Example 2: 5000 Users Full UC Profile - IM only active/active deployment

You have 4700 users on each node in your presence redundancy group in an IM-only deployment. Ciscorecommends that you round up to the nearest value, so using the 5000 users full US (4 vCPU 8GB) active/activeprofile you retrieve the lower and upper retry value based on a number of users value of 5000:
