Working Problems

Problem

Emergency shutdown of BI server process with activated performance tests.

Cause

Emergency shutdown occurs due to triggering of data execution prevention (DEP). When measuring memory consumption, memory allocation or deallocation function calls are intercepted. This is done by recording executable code bytes to memory that triggers the prevention.

Solution

Memory is measured only if data execution prevention is disabled. The prevention can be disabled as follows:

1. Select the System > Advanced System Settings item in the control panel.

2. Click the Settings button on the Advanced tab in the Performance area.

3. Select the Turn On DEP for Essential Windows Programs and Services Only radio button on the Data Execution Prevention tab or add appropriate exceptions:

• When IIS are used, add the w3wp.exe file located in the C:\Windows\System32\inetsrv\ directory to exceptions.

• When Apache web server is used, add the httpd.exe file from the directory with installed Apache web server to exceptions.

If metadata schema was earlier transferred Form Microsoft SQL Server 2008 to Microsoft SQL Server 2012, MDM dictionaries are not converted. Transferring of schemas between different DBMS versions is not supported due to difference in SQL syntax.

Solution

Update MDM repository by means of repository manager (RepoMngr.exe). After the successful update repeat dictionary conversion.
