Technote (troubleshooting)
Problem(Abstract)
Unable to deploy maximo.ear file due to partial files being left over in the deployment directories.
Symptom
When attempting to install the maximo.ear file the following message is received.
ADMA5016I: Installation of MAXIMO started.
A composition unit with name MAXIMO already exists. Select a different
application name.
Cause
This is caused by a previous failed deployment which left deployment files in the WebSphere directory.
Resolving the problem
To resolve this issue, delete the following deployment folders, replacing MAXIMO.ear with the name of the ear file deployed.
\profiles\ctgAppSrv01\config\cells\ctgCell01\applications\MAXIMO.ear.
\profiles\ctgAppSrv01\config\cells\ctgCell01\cus\MAXIMO
\profiles\ctgAppSrv01\config\cells\ctgCell01\blas\MAXIMO
\profiles\ctgAppSrv01\installedApps\ctgCell01\MAXIMO.ear
\profiles\ctgDmgr01\config\cells\ctgCell01\cus\MAXIMO
\profiles\ctgDmgr01\config\cells\ctgCell01\blas\MAXIMO

Look for <deployedApplications>maximo.ear</deployedApplications> and remove that line, once done try and redeploy the maximo.ear file.
