Which password?

Please don't doublepost.

First you need to change the password at the OS.

Then you need to run the right mqsi command to change the broker, or to set the database parameters.

What errors do you get when it starts up?

Are you sure you wanted to use the -a/-i flags to change the database password? There are two usernames/passwords on the mqsichangebroker command - One for broker service user and one for broker database user.

You can't change the user name for broker service user, and i don't think you can change the database user name either - you have to delete broker and recreate it to change those.

Jeff are you sure about the DB user? I believe if the new user has the correct access including to the right schemas (synonyms etc...) you might be able to change the DB user... never tried it though... would mean a lot of work on the DBAdmin side...

I'm not positive about the database, without double-checking it.

Hi, mqsichangebroker command doesn't offer you an option to change
the database user id. For database access, you can change only the password. (-p flag). If you need to change the DB user, then you need to recreate the broker.

On the other note, if the broker is created without -u , -p options, then database access userid/passwd will default to broker userid & password (specified at -i , -a). So if you change -i,-a using mqsichangebroker then it will change the database access credentials also. In such case you need to make sure that new userid has the right permissions to access the database.(otherwise the broker would not start).

The above post is in connection to the broker database and not the user database. If the user wants to change the "user" database access credentials , then mqsisetdbparams command can be used.
