503 issue in ibm WCS

Problem

Creating, formatting, and reading packet traces is sometimes required to resolve problems with IBM WebSphere  Edge Server. However, the most appropriate tool varies, depending on operating system.

Resolving the problem

Available for multiple operating systems

Wireshark is useful and a freely available tool that can read files and capture packets on almost any operating system.

Solution :

1.     Run iptrace on AIX interface en1 to capture port 80 traffic from a single client IP to a server IP:

iptrace -a -i en1 -s clientip -b -d serverip -p 80 trace.out

This trace will capture both directions of the port 80 traffic on interface en1 between the clientip and serverip and send this to the raw file of trace.out.

2.     Reproduce the problem, then run the following:

ps -ef|grep iptrace
kill -15 <pid>

Trace tools like Wireshark can read trace.out files created by iptrace
