CRIMC1066E ERROR: Unable to acquire lock on file .imlock''.

Hello Everyone,

Happy New Year 2016 to all readers. It's 1st week of the new year and I am getting new error while initiating IBM Installation Manager console.

CRIMC1066E ERROR:   Unable to acquire lock on file  /export/localhome/was/var/ibm/InstallationManager/.imlock''.

Problem:

While executing command ./imcl -c to launch the command line console of IBM installation manager it displays the following error message.
CRIMC1066E ERROR:   Unable to acquire lock on file  /export/localhome/was/var/ibm/InstallationManager/.imlock''.
The installation manager could not be started because another installation manager instance is already running. Only a single installation manager may be running at any time.

Cause:

We are getting this error if the installation manager is already running by some other user. When we start Installation manager the user create lock file .imlock which not allow other user to run installation manager to other location. This file get deleted when you close the installation manager. In some case if installation manager process got killed accidentally the lock file remains as it is and not allow you to start the installation manager next time and showing the error code. 

Resolution:

1. Ensure that there is no running Installation Manager instance.
2. If there is an Installation manager process running, delete that process
Unix: ps -ef | grep imcl or  ps -ef | grep java (Run these commands to find the process)
Windows: Go to the Task Manager and terminate all the java.exe, javaw.exe and IBMIM.exe processes.
3. Re-launch Installation Manager.

If the above steps do not resolve the issue, follow these steps:

1. Go to location list in the error code and manually delete .imlock file.
Unix: ls -a (use this command to list down the hidden files)
2. Hope this will not require, but if necessary, restart the system.

Hope this will help you. Kindly comment for your suggestion and quires.
