Hi
I am trying to access a remote oracle db from my copute node. The target database needs username guest and password for authentication. My broker runs on db2admin/db2admin. How can my compute node/broker access the remote database. Do I have any options to set at my end. ur inputs highly appreciated.
regards
shaker

| Thru the compute node, MQSI will connect to the database using the userid that the broker runs under. Your only other option is to write a custom node that establishes its own connection to the db. |

hi thnx for the reply,
i even changed the service userid and changed the username under which the windows service is running to guest (the target userid / pw required).. looks it is only taking the userid that is used to create the broker.. i am not looking at a custom node.. is there any simple way to use the user id required by target system (db).
regards,
shaker

shaker,
There are two user-id's related to WMQI
1) service user-id - This id is used to start the service.
2) db user-id - This id is used to access remote or local database.
So you need to change db user-id of your broker to guest.
I would recommend that you grant permissions to existing db user-id on oracle database.

I don't think you can change db user-id directly for the broker/configmgr. You might have to recreate the broker for this. There is no option to change dbuser-id in mqsichangebroker/mqsichangeconfigmgr commands.
That's why i said, I would prefer to define new user-id into database. It is much more simpler than recreating the broker.

thnx kiran,
i wanted to make sure that i am really at the end of the tunnel.. dont u think there should be some mechanism to accommodate such requirements? We end-up talking to so many databases and each time we force to add username.. think of adding db2admin on oracle?
thnx again for ur effort
regards
shaker

shaker,
I think it is more of a design issue. When you design mqsi broker domain, you should create db-user-id and service-user-id globally (like domain user). db2admin is not a global user-id, instead you can have some meaningful user name related to your application.
I think it is not that simple to chage db-user-id, that's why IBM didn't expose this option. In worst case the command might end up deleting and recreating all broker table, which is same as mqsideletebroker.

Ya.. u may be right.. there must be some issue in exposing the db user. And I was mentioning db2admin as an example .. in real time we will have different users for different databases.. and each time we are accessing a new database.. we need to 'request' to add a user name (what ever it may be) to that database. May be we have to live with it.
regards

Hi,
I just want to get some clarification on which user-id the broker will use to access an external database. Let say my WMQI service user id and password are "myuserid/password2002". When I installed DB2 I used the userid and password of "db2admin/password2002". When I created my broker, I don't think I specify a datasource userid and password. So when the broker tries to access an external database, it will use the servicer user id and password "myuserid/password2002", correct ? I would have to define the service id/password to the external database in order for the broker to access its tables ?
Thanks,
Alex |

Alex,
Yes, the broker will use myuserid/password2002 to connect to external databases, so you will have to define this userid/pwd into your database with appropriate authorizations.

 I am not sure if this is relevant but I was thinking that you could set the userid/password at datasource or odbc level. In the Administration Manual (Chapter 2 ...DB Setup and config) it gives an example of .odbc.ini entries for Oracle. In the 2.0.2 manual this includes user/password
| Code: |
[ORACLEDB]
Driver=/usr/opt/mqsi/merant/lib/UKor816.so
Description=Oracle8
ServerName=YourServerName
LogonId=scott
Password=tiger
EnableDescribeParam=1
OptimizePrepare=1
|
whereas in 2.1 manual the loginid and password are no longer there
| Code: |
[ORACLEDB]
Driver=/usr/opt/mqsi/merant/lib/UKor816.so
Description=Oracle8
ServerName=YourServerName
EnableDescribeParam=1
OptimizePrepare=1
WorkArounds=536870912
WorkArounds2=2
|
Maybe some use could be made of this. |

| I understand that CSD 3 for WMQI 2.1 has introduced more options for Database authentication. |
