The Final Furlong - Installing WebSphere Application Server 8.5 on a remote Linux server via Job Manager

This is the final ( for now ) instalment of my series covering the remote installation and management of WebSphere Application Server 8.5 using the Job Manager service that was introduced in WAS 7.0 in 2010.

Following on from the last two posts: -

I now have IBM Installation Manager (IIM) installed and configured on my remote server.

I've also used the IBM Packaging Utility: -

to create a repository ( located on the server that's hosting Job Manager ), containing the WAS 8.5 

Initially, I was going to use the submitCommand task within Job Manager to have the remote server execute a shell script ( install_WAS_via_HTTP.sh ) which would drive IIM to install WAS 8.5 using a response file ( installWAS85_via_HTTP.rsp ).

However, I found an even more elegant solution - the manageOfferings task - which avoids the need to deploy any files to the remote box .... or so I now know :-)

So I decided to dispense with the Job Manager GUI, and instead submit the manageOfferings task via wsadmin as follows: -

$ cd 
./wsadmin.sh -lang jython -user wasadmin -password passw0rd
wsadmin> AdminTask.submitJob ('-jobType manageOfferings -targetList rhel6.uk.ibm.com -username wasadmin -password passw0rd -jobParams [ [responseFile /tmp/installWAS85_via_HTTP.rsp] [acceptLicense TRUE] [IMPath /opt/IBM/InstallationManager] ]')

which I expected to start IIM ( from /opt/IBM/InstallationManager ) and install WAS using the response file /tmp/installWAS85_via_HTTP.rsp ( which I'd previously uploaded and unpacked ).

Imagine my surprise when this completely failed with: -

CWMRI1077E: Command manageOfferings failed on host rhel6.uk.ibm.com. The exception is "CWMRI1052E: The specified response file path name is invalid or the specified response file does not exist.".

Can you spot the obvious mistake ?

Yes, I was expecting Job Manager to look for the response file on the target remote box rather than on my own local machine ( from whence I'm running Job Manager ).

Can you say "Doh!" ??

Of course, this obviates the need for me to deploy the installation script and response file across to the target box - Job Manager will read the response file locally, and that's all it takes :-)

Once I changed the wsadmin command: -

AdminTask.submitJob ('-jobType manageOfferings -targetList rhel6.uk.ibm.com -username wasadmin -password passw0rd -jobParams [ [responseFile /mnt/hgfs/Source/Scripts/installWAS85_via_HTTP.rsp] [acceptLicense TRUE] [IMPath /opt/IBM/InstallationManager] ]')

it worked like a dream, as evidenced by the log files within Job Manager: -

Right, now it's time to use Job Manager to create a profile on the remote box, and then go and grab a cup of tea :-)
