Informatica, any expert know the error reason? ora-00942

Question

I am newbie to informatica. Any help is really appreciated
When I run the workflow, I got session error. The detailed session log is under below.
I am using oracle11g and informatica 9.0.1
The main reason is table or view is not exist, like this
2011-09-22 14:36:04 : ERROR : (3696 | WRITER_1_*_1) : (IS | inte6) : node01_ang : WRT_8229 : Database errors occurred:
ORA-00604: error occurred at recursive SQL level 1
ORA-00942: table or view does not exist
So I am wondering:
1) I setup ODBC data source user and ODBC target user, now ODBC source user
have all source data. So, after mapping, am I supposed to have any table definiton
in the target user? where is the target table definiton?
2)Probably, I set up wrong connection. Before I create session, I create native connection. When I create native connection to both source and target database, right? When I create native connection, I need source database user and target
database user. I am confusing, what kind of user should I use? I create two new
users having DBA privileges in both database. Am I wrong?

Answer 1

Mark, thank you very much.
I installed the odm followed the tutorial, and the system did not imply the error.
I could see the data mining interface and the dmuser after connecting.
What’s more, somebody once built the model successfully, now the error appeared again.
What caused the problem, how to solve it?
I was about to be crazy to the problem. I have to do some research on data mining to get the information of the data, so I choose the odm tool. But the error stopped the reach. I ‘m afraid if this problem could not be solved ,which one should I choose.
By the way, I downloaded the odm from oracle.com. I don't know where to get the licence.
