Setting the number of processes

By default, three processes are started. You can change the number of processes in the Management Console:

1. From the context menu of the proxy, select the item Edit Properties.

2. In the Edit Properties of Local/Remote Proxy property sheet choose the Performance Settings tab.

3. Under Number of Proxy Container Processes change the value for Total.

The maximum number of processes is limited by internal settings to 240. You should also take into account that a higher number of processes also increases the system overhead for managing those processes and affects the size of the recovery file.

Moreover, additional virtual memory is required for each process of a proxy container. For example, when running on Solaris systems in 32-bit mode, each additional utmwork process requires approximately 30-40 MB of additional memory. The precise requirement is dependent on the configuration.

Caution!

If too little physical memory (RAM) is made available then the system transfers memory areas to hard disk (paging). This can drastically slow down operation.

If there are more than 50 processes to be started, you additionally have to change the statements MAX TASKS, MAX TASKS-IN-PGWT and/or MAX ASYNTASKS in the file input.system.txt manually.

You find the file input.system.txt

• on Solaris and Linux systems under the directory:

  <Proxy_home>/def

• on Windows systems under the directory:

  <Proxy_home>\def

Adapt the statements as described in the following text:

• MAX TASKS=<number>

  To increase the number of processes, increase the value for <number> in this statement. <number> specifies the maximum number of processes.

• MAX TASKS-IN-PGWT=<number>

  <number> specifies the maximum number of messages for outbound communication, which can be processed in parallel.

• MAX ASYNTASKS=<number>

  <number> specifies the maximum number of asynchronous messages for inbound communication, which can be processed in parallel.

To activate these changes you have to carry out an update configuration and restart the proxy (see Saving and activating the configuration of the BeanConnect proxy ):

1. From the context menu of the proxy, choose the item Update Configuration.

2. From the context menu of the proxy, choose the item Start Proxy.
