903: Ssis

Paper Title: The Critical Role of the Duty Officer (SSIS 903) in Los Angeles County Sheriff’s Department Operations

Date: October 26, 2023 Subject: Operational Overview of the Duty Officer Position (SSIS 903) Prepared For: Administrative Review / Law Enforcement Policy Board

Real-World Example: Fixing SSIS 903

Scenario: A financial ETL process running every night fails at 2:00 AM with SSIS 903. The package processes 2.5 million rows from a flat file into a SQL Server table.

Diagnosis: The server had 8 GB RAM, but other jobs consumed 6 GB. The package DefaultBufferSize was 10 MB, and DefaultBufferMaxRows was 10,000. ssis 903

Solution:

1. Increased server RAM to 16 GB.
2. Set DefaultBufferSize = 30720 (30 MB).
3. Reduced DefaultBufferMaxRows = 5000.
4. Split the Data Flow into two parallel streams using a Conditional Split.

Result: Error 903 vanished. Throughput improved by 40%. Paper Title: The Critical Role of the Duty

How to Diagnose SSIS 903

Because the error message is vague, follow this methodical approach:

1. Metadata Mismatch Between Source and Destination

Even if your package validates successfully, a late-bound metadata change (e.g., a column’s data type altered in a staging table or source view) can cause the PrimeOutput method to fail. SSIS buffers are allocated based on metadata at runtime; a mismatch leads to pointer errors. Increased server RAM to 16 GB

3. Alternative Acronyms for "SSIS"

If you are not working with Microsoft databases, SSIS could mean:

• Ship Security Information System (maritime/IMO regulation) – No “903” reference exists here.
• Social Security Information System (various governments) – No “903” reference.

3. Check the Script Task (if used)

• Wrap your script code in a try...catch and log the actual exception:

  try 
      // your code
   catch (Exception ex) 
      Dts.Events.FireError(0, "Script Task", ex.ToString(), "", 0);
      Dts.TaskResult = (int)ScriptResults.Failure;
  

Step 1: Isolate the Failing Component

Run the package in Visual Studio with Data Flow Task breakpoints. Disable components one by one. If the error disappears after disabling a specific transformation or destination, you have found the culprit.
