 1. Java on AIX isn't supporting IPv6 properly. Fix by inserting "-Djava.net.preferIPv4Stack=true" into JAVA_OPTS
 2. Your networking configuration is not correct. If you attempt to ''ping localhost'' and don't see '''127.0.0.1''' you need to look into your /etc/host.conf (most Unixes/Linux) or /etc/netsvc.conf (AIX) file to ensure that something like ''"hosts = local, bind"'' is present.

Preface

Questions

  1. When I run ps (on Linux), why do I see my java process a bazillion times!

  2. How do I run without an X server and still get graphics?

  3. Tomcat dies after I log out!

  4. Catalina.log contains : "SEVERE: StandardServer.await: create[8005] : Throwable occurred: java.net.BindException: The socket name is not available on this system."

Answers

When I run ps (on Linux), why do I see my java process a bazillion times!

Linux implemented threads as processes. Due to other gory details that is beyond the scope of this FAQ - the ps command doesn't work correctly with respect to threads. You can get more gory details here and here .

How do I run without an X server and still get graphics?

You either need to run headless or run an alternate X-server. Some more information can be found here, here, or here. Or if your are using a JVM 1.4 or better, you can use the system property java.awt.headless=true

Tomcat dies after I log out!

This is a common complaint when using Solaris. Make sure you use nohup and see this thread

Error message: "SEVERE: StandardServer.await: create[8005]: Throwable occurred: java.net.BindException: The socket name is not available on this system."

This error message can have 2 causes:

  1. Java on AIX isn't supporting IPv6 properly. Fix by inserting -Djava.net.preferIPv4Stack=true into JAVA_OPTS

  2. Your networking configuration is not correct. If you attempt to ping localhost and don't see 127.0.0.1 you need to look into your /etc/host.conf (most Unixes/Linux) or /etc/netsvc.conf (AIX) file to ensure that something like "hosts = local, bind" is present.
