I have an issue with IBM DB2 console. After updating expired certs (using this instruction) it just stopped work. It happened just right after I uploaded the new cert using web console web interface.
$ openssl s_client -showcerts -connect X.X.X.X:8443
Connecting to X.X.X.X
CONNECTED(00000003)

The database cluster itself works well.
How can I check DB2 Console certs? Does DB2 store them in a location returned by "db2 get dbm cfg" command? Can I temporarily disable SSL certs for the console to make it work?
