Subject RE: Sshexec fail on starting a service (websphere)
Date Wed, 03 Mar 2004 22:40:24 GMT
I maybe figured out why its still hanging.  When the websphered script is
called it invokes serverStart.sh then it invokes actual java process.  This
process never dies, because the server is now running.

but for some reason sshexec /or jsch is not noticing that the service is
started...aka  [ OK ] from the websphered script.

Maybe its an issue with sshexec or probably jsch.
http://cvs.apache.org/viewcvs.cgi/ant/src/main/org/apache/tools/ant/taskdefs
/optional/ssh/SSHExec.java?rev=1.14&view=auto
The code SSHExec waits until it gets an EOF from the channel.
 while (!channel.isEOF()) {

It sure would be nice to based on the output what is recieved from the
channel, to determine from their if it failed or not.

Ie....  >   [sshexec] Shutting down websphered: 
>   [sshexec] [  OK  ]

This <websphered> script is called on boot of the server.  It works fine
outside of ant / wsad

Would this be a good suggestion for the SSHExec task?  I can write the code,
if necessary.  It doesn't look to complicated.

Thoughts....from ANT developers.

Thanks again.

Depending on what is running in your WebSphere environment, it may take a
really long time to start. Try timing how long it takes to start up and then
adjust your timeout attribute accordingly. Time it from remote...

time ssh user@host "/etc/init.d/websphere start"

Another option is to background the start command, but then ant will exit
successfully whether or not websphere starts successfully.
