A composition unit with name MyApp already exists. Select a different application name.
This is most frequently observed during the installation or removal of applications, but it may also turn up during other administration tasks such as deleting servers.
The issue is a WebSphere Application Server defect.
If there is an error with the deployment of a module,then this bad deployment is saved, then the WebSphere Application Server configuration will be out of sync.
Even after the application is removed, you might not be able to do any further or new appi
The manual workaround is to delete the /blas and /cus directories for the bad application from the config.
The WebSphere Application Server team has built interim fixes for this defect for WebSphere Application Server V220.127.116.11 and V18.104.22.168. If needed they can be obtained from the WebSphere Application Server Support Team.
A technote for this issue will be forthcoming.
