But the module which I am trying to remove is not in the /OPT/OPENERP/SERVER/OPENERP/ADDONS directory.It has been already removed.Can anyone please help in sorting out this issue?

This normally happens when you have a one2many or other types of links to relations in a module that you want to uninstall. Fist check that the module that you want to uninstall has any relation with other modules?. Remove the dependencies so that each module can be independently installed and uninstalled.

I completely messed up my custom module and had to uninstall it manually.

I had to get the ID of each model that I created in my custom module:

"select * from ir_model where model like '%my_model_name%';"

And then delete the contrainsts, relations and models from the DB by replacing <ID> with your particular ID from above.

"delete from ir_model_constraint where model = <ID>;
delete from ir_model_relation where model = <ID>;
delete from ir_model where id = <ID>;"

After this, the uninstall worked.  I wouldn't do this on a live system.  I have no idea about the long term consequences but it seems to be working fine on my dev platform.
