When working with BI Connector and Oracle Fusion, errors may occur during query execution or data fetch. Debugging these issues becomes easier by checking the BI Connector log files, identifying the error message, and applying the right fix. Below is a quick guide on how to access logs and troubleshoot common Oracle errors.
How to Access BI Connector Log Files?
1 . Using BI Connector UI:
- Open BI Connector
- Go to the Help Center tab
- Click Download Logs to save the latest logs as a ZIP file
2. Using File Explorer:
- Open File Explorer on the BI Connector machine.
- Navigate to: C:\ProgramData\Guidanz\BI Connector\logs
- You will find the log files in this folder.
Identify the Right Log File to Search
- For Data Model issues: Check bip.log
- For Subject Area/Analysis issues: Check biconnector.log.
- Search for the keyword ERROR.
- Check the log entries around the time the failure happened.
Possible Error Scenarios
- Invalid Identifier
Error Message:
"ColumnName": Invalid identifier
Reason:
The column name in the SQL query does not exist in the table or it is misspelled.
Suggestions:
1. Please check the SQL query you used to create the data model , and confirm the column name exist in table.
2. If you using data pipeline , ensure that the watermark column, primary key columns are correctly spelled and exist in the source table.
3. Double-check for typos in column names.
2. Table Not Found
Error Message in log:
Table or View does not exist
Reason :
Invalid Table name or table does not exist
Suggestions:
Fusion table names are case-sensitive , Please make sure that you have entered the correct table name.
3. Authentication Error

Suggestions:
Provide the correct username and password in the Data source in BI Connector.
4. Report Does Not Exist
Error Message in log:
The Report path does not exist / Report path is invalid / Path not found
Reason:
The Report you are trying to load in BI Tools does not exist.
Suggestions:
1. Verify in Oracle Fusion / OAC environment , the report exist or not.
2. Check if the report path entered in BI Connector is correct and matches the exact folder structure in Oracle Fusion / OAC.
5. Data Model Does Not Exist
Error Message in log:
Not able to get data set columns.
Reason:
The Data Model you are trying to load in BI Tools does not exist.
Suggestions:
Verify in Oracle Fusion / OAC environment , the data model exist or not and you have access to that data model.
6. Report Is Not Accessible
Error Message in log:
access denied for user to path
Reason:
The Report you are trying to load in BI Tools is not accessible with the current user's permissions.
Suggestions:
1. Verify that the user account has the necessary role and privileges to access the report.
2. Check if the report is shared with the user or role in Fusion / OAC and that folder-level permissions are correctly set.
7. Oracle Memory Issue
Error Message in log:
XDODataSizeLimitException / Payload too large / OutOfMemoryError / any error message with size limit , memory issue keywords
Reason :
For this particular table, the amount of data being fetched exceeds Oracle’s size limit and results in a memory-related failure during query execution.
Suggestions:
To resolve this, please follow the steps below:
1. Open BI Connector and edit that particular table.
2. Click on Settings.
3. Change the "No of Rows per fetch" value from 50,000 to 25,000.
4. Click on Apply and Save the table.
8. Query Timeout
Error Message in log:
504 Gateway Timeout / Read timed out / Bad Gateway
Reason:
The oracle is taking too long to process the query, and the connection is timing out.
Suggestions:
1. Check network connectivity between the BI Connector and Oracle Fusion.
2. Reduce the “No of Rows per fetch” in BI Connector for that particular table.
9. Invalid Oracle Fusion URL / Network Issue
Error Message in log:
ERR_NAME_NOT_RESOLVED / getaddrinfo ENOTFOUND
Reason:
The URL you provided in the data source in BIC is expired or invalid.
If you are able to access the URL in the browser, then it might be due to network issues.

1. Provide the valid Oracle Fusion account URL.
2. If you are able to access the URL in the browser, ensure a stable network connection.
10. Invalid SQL Query
Error Message in log:
Please verify the data model SQL query and associated parameters
Reason:
The SQL query sent to Oracle Fusion is invalid.
