I downloaded Data Studio and connected to DB2 Express-C in my Linux Mint 64-bit laptop. It was working fine. I was studying DB2 and trying to create a new instance and drop the old instance. I was able to drop the old instance but without dropping the sample database first.
Now I cannot connect to sample database in new instance in data studio.
It's showing SQL4499N A fatal error occurred that resulted in a disconnect from the data source.
I tried for the solutions mentioned here but could not fix the problem.
