Today while creating a mapping by using import method & template I got a pop-up with following error message in Designer:
03/30/2016 16:30:55 **** Importing Source Definition: tblCustomerResults ... : The first character in a name cannot be a number. ** Failed to Import: tblCustomerResults 03/30/2016 16:30:55 **** Importing Target Definition: tblCustomerResults ... : A column with the name 120_-_Unknown already exists. Please enter a unique name. ** Failed to Import: tblCustomerResults 03/30/2016 16:30:56 **** Importing Mapping: mACQtblCustomerResults ... : Could not find Transformation definition for: tblCustomerResults ** Failed to Import: mACQtblCustomerResults
With the above error its quiet evident that Informatica do not support column names that starts with a number. But to confirm I checked online and found it to be true and one of the biggest limitation in Informatica.
As a workaround:
1. I dropped the Source Connection pointing to the Original source.
2. I created the Source table in my Database and re-created the Source Connection pointing to this table.
3. Save and export the Source XML.
4. Finally Import the mapping by using same template and the new Source XML, successful 🙂
I also found that this limitation is not only with columns, but also with Source Table Name, Database Definition (DBD) name, Repository Folders, etc.
Informatica – WRT_8229, Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
Working with Informatica is fun, but challenging at times, don’t know if this is the same other ETL tools, like SSIS, etc.
Today, while running a Workflow I was getting an error on a session, and due to this the rows were not getting inserted from Source to Target table. The error is as follows:
Timestamp: 1/25/2016 3:37:43 PM
Process ID: 7180
Message Code: WRT_8229
Message: Database errors occurred: Microsoft OLE DB Provider for SQL Server: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
Database driver error…
Function Name : Execute Multiple
SQL Stmt : INSERT INTO dbo.Contact (Id,Name,Description,CreatedBy,CreatedOn,ModifiedBy,ModifieOn,RowCheckSum) VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
I check all the place and at last found that the last column “RowCheckSum” as mentioned in the error above, was not present in my Target table.
So, I just went ahead and added this column with simple “ALTER TABLE ADD COLUMN” statement.
And post this fix, my Workflow ran without any issues, and I got the table populated as expected.
Today while executing a new Informatica Workflow that I designed I got a pop-up with following error message:
“There is no Integration Service found for this workflow”
The Workflow was not getting kicked off and there was nothing else showing up other than the error message box.
Thus, I did a bit research and as the error message indicates found that the Workflow needs to be linked to an Integration Service so that the data movement could be enabled from Source to the Target.
The Informatica Integration Service (or infasvcs) acts as a controller for entire workflow execution. Integration Service gets into action whenever a workflow is kicked off (either manually or by schedule). It reads Workflow, Session/Task and Mapping information from Repository Database and performs the execution as per transformations defined.
–> Right-click on the Workflow Designer and this opens up following window, which shows the Integration Service text box empty, below:
… you just need to click on the button adjacent to it (circled, above), which opens up following window:
… here, you just need to select the Integration Services listed and click OK. Post this you will see the text box populated with the Integration Service name.
–> But if you want this to be assigned for more than one Workflow or to be executed with different Integration Service than you can go with this approach:
Close all the Workflow Folders.
And in main-menu click Services –> Assign Integration Service
… this will open following window below, and here you can select more than one Workflow and select Integration Services for them:
