I'm able to run db2tsrt on the linux system. But when I tried to open the control center using db2cc command, it is throwing an exception "unexpected exception during linking:
java.lang.ClassNotFoundException: javax.swing.JApplet"......

I've installed IBMJava2-131 on the system and had given the JAVA_HOME in .bash_profile of the User and exported the same.

Even I tried it giving the path on /etc/profile but the result is the same.

Can anybody help me out solving this issue.....
Thanks in Advance....

db2tsrt -- What is this ?

It sounds like you setup JAVA_HOME but forgot to setup the rest of the shell variables. This is what I have on my system:

JAVA_HOME=/usr/java/jdk1.4.2_03

PATH="$PATH:$JAVA_HOME/bin"

CLASSPATH=$JAVA_HOME/lib

Put the above in your /etc/profile (modifying the path of course)

and then type source /etc/profile to load the variables up.

Then db2cc should work.
