Hi Ashutosh,
Now unfortunately the configtool is also not opening.
Initially when configtool was opening, I went to secure store area and changed the databasename = ABC which is db of my system which is down from XYZ which is the db name of another system mounted on this machine, but since then the configtool is not coming up.
how to change the databasename parameter in secure store now as the configtool is not opening.
