To prevent different processes from generating duplicate
configuration session or workspace IDs within the same millisecond,
you must set a JVM custom property.
Before you begin
Expected state:
- Single server: the Sametime® Gateway
Server is started.
- Cluster: the deployment manager is started.
About this task
In a single-server environment, apply this property to the
JVM on the Sametime Gateway
server. In a clustered environment, apply this property to the
following servers, proxies, nodes and the cell's deployment manager
in the Gateway cell:
- Sametime Gateway
Servers
- WebSphere SIP Proxy Servers
- Deployment manager for the cluster
- All nodes in the cluster
Procedure
- Log in to the WebSphere Integrated Solutions Console as
the administrator.
- In the navigation tree, click .
- In the table of application servers, click the name of
the server you want to modify.
- On the Configuration tab, locate
the Server Infrastructure section, and click .
- In the Additional properties section,
click Java Virtual Machine.
- A new Configuration tab displays.
In the Additional properties section, click Custom

Note: If this property already exists, make sure the value is
set to random.
- Click OK.
- In the "Messages" box at the beginning of the page, click Save.
- Complete one of the following steps:
- Single server -- Restart the Sametime Gateway Server.
This task is complete.
- Cluster -- Restart the cluster and then continue to the next
step to set this property for the cluster.
- Repeat this process for all application servers and node
agents in the cluster. In the navigation tree, select a server or
node agent:
- Application servers -- Click .
- Proxy servers -- Click .
- Node agents -- Click .
- Deployment manager -- Click .
- Create the new custom property or update an existing one
as you did in Step 7.
- In the "Messages" box at the beginning of the page, click Save.
- Synchronize the nodes and restart the cluster:
- In the navigation tree, click .
- Select all nodes in the cluster, and then click the Full
Resynchronize at the beginning of the table.
- In the navigation tree, click .
- Select a node agent, and then click Restart
all servers on Node.
