I'm experiencing some troubles with the execution of DB2 express c on Mac OSX 10.6 Snow Leopard.
I have installed the db system, creating two users, db2 and db2-user. The latter is the instance owner. I have sourced db2profile and the env variables seem to be set correctly.
Db2 starts successfully, but I'm not able to run db2sampl, the error is:
Attempt to start DB2 instance failed. SQL1019N The node name "db2-user" specified in the command is not valid.
I have googled the error and it looks like I have to change the DB2INSTANCE variable, but I do not know what value should be.
