Resolve OLAP Database Errors in Microsoft Project Server
Product
Microsoft Project Server
Device & OS
not provided
Scenario
Processing Microsoft Project Server queue jobs that require a connection to SQL Server Analysis Services.
Observed behavior
Queue jobs repeatedly fail with OLAP database and GeneralQueueJobFailed errors, indicating that the connection to the SQL Server Analysis Services server has failed.
Before you start

Ensure you have farm administrator privileges in Microsoft Project Server and administrative access to the SQL Server Analysis Services (SSAS) instance before attempting to troubleshoot server connections.

Solution 1Recommended

Verify SQL Server Analysis Services Status and Permissions

Check the SQL Server Analysis Services instance to ensure it is running, accessible, and that the Project Server accounts have the correct permissions.

The GeneralQueueJobFailed error typically occurs when Project Server is unable to communicate with the OLAP cube backend. Ensuring the SSAS service is running and properly configured is the first step in resolving this issue.

1
Log into the SSAS Host

Access the server hosting your SQL Server Analysis Services instance via Remote Desktop.

2
Check Service Status

Open SQL Server Management Studio (SSMS) and attempt to connect to the Analysis Services instance to ensure it is actively accepting connections.

3
Verify SQL Server Browser

If you are using a named instance for SSAS, open 'services.msc' and verify that the SQL Server Browser service is running.

4
Validate Account Permissions

In SSMS, verify that the Project Server application pool service account has been granted administrative permissions on the SSAS instance.

Frequently Asked Questions

What causes the GeneralQueueJobFailed error in Project Server?

This error typically occurs when the Project Server queue service cannot communicate with backend services. It is most often caused by a timed-out SQL Server Analysis Services connection, network interruptions, or incorrect service account permissions.

How do I restart the Project Server Queue Service?

Open the Services console (services.msc) on your Project Server application server, locate 'Microsoft Project Server Queue Service', right-click it, and select 'Restart'. This can sometimes resolve temporary queue hangs.

Does WPS Office integrate directly with Microsoft Project Server?

No, WPS Office is an independent suite designed as a lightweight alternative to Microsoft Office desktop applications. It handles standard documents, spreadsheets, and presentations, but does not natively connect to Microsoft Project Server's enterprise OLAP cubes.
