Bug #: 50002099 (SQL Hotfix)
Microsoft distributes Microsoft SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.
This article describes the following about this hotfix release:
- The issues that are fixed by the hotfix package
- The prerequisites for installing the hotfix package
- Whether you must restart the computer after you install the hotfix package
- Whether the hotfix package is replaced by any other hotfix package
- Whether you must make any registry changes
- The files that are contained in the hotfix package
Consider the following scenario. You have an application that connects to an instance of Microsoft SQL Server 2000 Analysis Services by using Microsoft OLE DB Provider for OLAP Services 8.0 (Msolap80.dll). In the application, you try to obtain property sets that are supported by the provider. One of the property sets contains more than 64 properties. On the computer, you use the Page Heap tool (Pageheap.exe) to troubleshoot heap corruption issues for the application process. You run the following command on the computer:
Pageheap.exe /p /enable ProcessName /fullIn this scenario, you experience one or more of the following symptoms when you run the application:
- You receive incorrect data from Analysis Services.
- An access violation occurs.
- A minidump file is generated in the Analysis Services log folder.
This problem occurs because the Microsoft OLE DB Provider for OLAP Services 8.0 uses an 8-byte bitmap for each property set to count the supported properties.
An access violation may occur when the following conditions are true:
- A property set contains more than 64 properties.
- The application reads the data beyond the allocated buffer.
