Ssis-969 !!top!! <2025>

The SSIS-969 error code often relates to issues with the execution of packages, which could stem from various sources such as:

1. Connection Issues: Problems connecting to servers or databases.
2. Package Validation Errors: Errors that occur when the package is being validated, often due to incorrect configurations.
3. Permissions Issues: Lack of necessary permissions to execute the package or access certain resources.

Here are some general steps you can take to troubleshoot an SSIS-969 error:

What is SSIS-969?

SSIS-969 could refer to a specific version, model, or specification within a larger system or product. However, without direct context, it's challenging to pinpoint exactly what it represents. It's essential to consider that such designations are often used in the software, technology, and data management sectors to denote particular products, updates, or standards. SSIS-969

Steps to Reproduce

1. Open the package Load_Fact_Sales.dtsx in SSDT.

2. In the OLE DB Destination, set the Data Access Mode to Table or view – fast load. The SSIS-969 error code often relates to issues

3. Enable Keep identity, Keep nulls, Table lock, and Check constraints.

4. Execute the package (Debug ► Start) or schedule it via a SQL Agent job. Here are some general steps you can take

5. Observe the Data Flow task progressing through the first ~10 000 rows without error.

6. After the last batch is sent to the server, the task fails with:

   SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on component "OLE DB Destination"
   (1) returned error code 0xC0202009. The component returned a failure code when the pipeline engine
   called PrimeOutput(). The error is fatal and the pipeline stopped. 
   Object reference not set to an instance of an object.
   

What does SSIS-969 address?

The hotfix corrects a buffer memory leak that occurs when:

• You run two or more DataFlow Tasks concurrently in a single package (using Sequence Container with MaxConcurrentExecutables > 1).
• The data flow contains asynchronous transformations (e.g., Sort, Merge Join, Union All).
• The server is under moderate memory pressure.

Symptoms before SSIS-969:

• Gradually increasing private bytes of the ISServerExec.exe process.
• Sporadic System.OutOfMemoryException even with sufficient RAM.
• Hang during the PostExecute phase of the DataFlow task.

Recommended Permanent Fix

1. Apply the latest Cumulative Update for SQL Server 2019 (CU15 or later). The fix in CU14 addresses a NullReferenceException occurring when the OLE DB Destination uses FastLoad with Table lock and Check constraints.
2. Validate the OLE DB provider version – ensure the package is using Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL) 19.x rather than the older SQLNCLI11.
3. Add a “Data Flow Buffer” checkpoint (via a Script Component that writes the row count to a variable) to confirm the exact batch size that triggers the failure.

Impact

• Data integrity – Partial loads require manual cleanup/re‑run.
• ETL schedule – Jobs that depend on this package stall, causing downstream pipelines to miss their SLA.
• Resource waste – Re‑processing of large data volumes increases CPU and I/O consumption.
