我用我的程序连接ORACLE数据库，可是提示“灾难性故障”，然后就登录不上了，除非机器重启才能再次连上（或重启ORACLE服务）。我的连接字符串如下："Provider=OraOLEDB.Oracle;PLSQLRSet=1; Data Source=MYDB; User Id=sa; Password=123"
我查找了一下ORACLE公司的帮助，如下：

5. Oracle Objects for OLE (OO4O) you will receive one of the following errors:
a) Oracle Provider for OLE DB Error Type: Microsoft OLE DB Service Components (0x80070005) Access is denied.
b) Microsoft OLE DB Provider for Oracle Error Type: Microsoft OLE DB Provider for Oracle (0x80004005) Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. Or Error Type: Microsoft OLE DB Provider for Oracle (0x80004005) Oracle error occurred, but error message could not be retrieved from Oracle.
c) Oracle ODBC Driver Error Type: Microsoft OLE DB Provider for ODBC Drivers (0x80004005) Specified driver could not be loaded due to system error 5 (Oracle in OraHome92).
d) Microsoft ODBC for Oracle The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3 (or greater) client software installation.

i. while using a GLOBAL.ASA file Error Type: Active Server Pages (0x0) An error occurred while creating object ’OraSession’.
ii. not using a GLOBAL.ASA file Error Type: Microsoft VBScript runtime (0x800A0046) Permission denied: ’CreateObject’ (6)
f) Other miscellaneous errors
The Specified Module Could Not Be Found Solution Description -------------------- You need to give the Authenticated User privilege to the Oracle Home by following these steps:
i. Log on to Windows as a user with Administrator privileges.
ii. Launch Windows Explorer from the Start Menu and and navigate to the ORACLE_HOME directory.
iii. Right-click on the ORACLE_HOME folder and choose the "Properties" option from the drop down list. A "Properties" window should appear.
iv. Click on the "Security" tab on the "Properties" window.
v. Click on "Authenticated Users" item in the "Name" list (on Windows XP the "Name" list is called "Group or user names").
vi. Uncheck the "Read and Execute" box in the "Permissions" list (on Windows XP the "Permissions" list is called "Permissions for Authenticated Users"). This box will be under the "Allow" column.
vii. Check the "Read and Execute" box. This is the box you just unchecked.
viii. Click the "Apply" button.
ix. Click the "OK" button.
x. You may need to reboot your computer after these changes have been made. Re-execute the application and it should now work.
Explanation ----------- If you install Oracle9i Release 2 (9.2.0.1) on a computer running Windows with an NTFS partition, the contents of ORACLE_HOME directory will not be visible to users who are authenticated on that machine. These permissions were not set properly when the software was installed. Applications that were working fine with previous versions of Oracle software will stop working when they upgrade to Oracle 9.2.
NOTE: The application will continue to work if the user has logged onto the machine as an Administrator. Any application that is using the Authenticated User privilege will not work. A notable example would be IIS which might service some of the requests based on the Authenticated User privileges. To demonstrate the problem in further detail, you can log on to the operating system as an authenticated machine user. You won’t be able browse the contents of the ORACLE_HOME directory demonstrating your inability to load any Oracle DLLs or make a connection.
