Modify the number of connections the Policy Server supports by changing the Max Connections value on the Settings tab of the Policy Server Management Console for each of the Policy Server.
Generally, there is no reason to decrease the default number of connections (256). You should only increase the value if the Web Agents served by the Policy Server require additional connections.
The maximum number of connections that the Policy Server can support is determined by the following settings:
A proper nofiles(descriptors) setting is required on Solaris Policy Servers to accommodate the sockets being opened by the Web Agents. This configures the ulimit or the number of file descriptors available to each Policy Server service. The ulimit should be set to at least 1024, and may be higher depending on the system needs and the version of Solaris being used. To set nofiles(descriptors) to 1024, for example, run ulimit –n 1024; this command usually is placed in smuser's .profile file so that it runs whenever smuser logs in (su – smuser). The nofiles(descriptors) value determines the maximum number of sockets and files which may be used at the same time by the process, which may include, besides connections to the agent, connections to such objects as the user directory and log files.
The Maximum Connections value may be increased up to just below the ulimit.
Note: There is a theoretical MaxConnections maximum of 32,000. However, CA recommends setting MaxConnections no higher than 10,000, which is the maximum tested value.
Note that some room must be left when setting Maximum Connections. For example, if it is calculated that there could be up to 1024 Web Agent connections, you should use the Settings Tab to set Maximum Connections to a slightly higher value, such as 1256.
