Issue/Introduction

Unable to connect to Oracle DB from the sql_response probe using OLEDB provider.

From sql_response log:

Mar 13 14:08:35:003 sql_response: Finding OLE DB Providers:
Mar 13 14:08:35:009 sql_response: [SQLOLEDB.1     ] Microsoft OLE DB Provider for SQL Server
Mar 13 14:08:35:020 sql_response: [MSDataShape.1  ] MSDataShape
Mar 13 14:08:35:021 sql_response: [SQLNCLI11.1    ] SQL Server Native Client 11.0
Mar 13 14:08:35:032 sql_response: [ADsDSOObject   ] OLE DB Provider for Microsoft Directory Services
Mar 13 14:08:35:063 sql_response: [MSDASQL.1      ] Microsoft OLE DB Provider for ODBC Drivers
Mar 13 14:08:35:069 sql_response: [MSDAOSP.1      ] Microsoft OLE DB Simple Provider
Mar 13 14:08:35:071 sql_response: [MSOLAP.6       ] Microsoft OLE DB Provider for Analysis Services 12.0

Environment

  • sql_response probe ver 1.66 or higher deployed on Windows server x86_64 platform.
  • Oracle client 12.2 32-bit installed on the Windows server.



     

Cause

  • The 32-bit Oracle client does not properly install the OLEDB provider on an x86_64 platform.

  • It is expected to see OLE DB provider: '[OraOLEDB.Oracle.1] Oracle Provider for OLE DB' to be loaded when starting the sql_response probe.


     

Resolution

Deploy 64-bit Oracle Client instead.

When finished run 'Regedit' command in a command line window and search the location listed below:

 \\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_HOMENAME (for example->  \\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraClient12Home1) the key OLEDB has been created.

  • Make sure \ORACLE_HOME\bin path has been added in OS lib path for OraOLEDBver.dll (for example OraOLEDB12.dll) to be loaded by applications and Nimsoft service has been restarted on this server after that.

  • An example of ORACLE_HOME for Oracle Client: 'E:\app\client\Administrator\product\12.2.0\client_1'

  • Remove folder \ORACLE_HOME\bin for 32-bit Oracle Client from OS lib path (the environment variable 'path' on Windows server) and remove its Home Key (if any) under \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\ for the 32-bit client. Remove the 32-bit client home from disk if it is not used by any application.
