It is important that the operating system have enough memory to run all Java functions required. Make sure that you leave a space before -classpath and the additional parameters.

Add the following parameters to the key before the -classpath parameter.

Under IBMServiceManager, double-click Parameters.

Search for IBMServiceManager, which should be located under HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services.

#TCP REDIRECTOR UPDATE#

Make the following changes directly in the Windows Registry to update the Java options: Server, it may indicate you need to modify these Java parameters. If you notice the Redirector unexpectedly terminating or the presence of javacore.* files existing on your The Java parameters -Xms and -Xmx may require modification if you attempt to load the Z and I Emulator for Web server

This allows the TCP protocol stack of Microsoft Windows to quickly detect the closed sessions and free up the resources.

In addition, shortening the KeepAliveTime forces the operating system to check on connections more frequently. Shortening the time from two hours to 30 minutes helps prevent TCP resources from being consumed by inactive sessions not fully closed.

If the Z and I Emulator for Web client disconnects from the Z and I Emulator for Web server for reasons other than logging off from the telnet session, it could take two hours for the Z and I Emulator for Web Redirector to close and free up all of the TCP connection resources being used between the Z and I Emulator for Web Redirector and Telnet server. This value can cause the operating system to keep TCP resources for connections that have terminated in use for two hours. The default value for this parameter is two hours. We suggest that you modify the value for KeepAliveTime.

Microsoft Knowledgebase Article 238643 describes other Microsoft Windows TCPIP parameters.

The value of this parameter should be 65534. We suggest modifying the existing registry entry or adding the parameter to the registry.

Most services and programs were stopped on the (data sent) 1/10 of a second after the previous transaction ended (data received). Each established connection then started a new transaction On average, the Redirector established 13 connections per second.
