Selecting a 32-bit or 64-bit Process for a Connector

On a 64-bit Coveo server, many connectors can run either in a 32-bit or 64-bit process. Setting a connector to run in 64-bit allows to take advantage of the 64-bit performance. However, in some cases, connectors need to run in a 32-bit process.

Example: When indexing PST mail archive files, the File connector uses a third-party library that does not support 64-bit processes and must therefore run in a 32-bit process.

Important: Selecting a 32-bit or 64-bit process for a connector affects all sources for this connector. Changing the state of the Run in 64 bits check box requires a refresh of all the sources of this connector.

To select a 32-bit or 64-bit process for a connector

1. On a 64-bit Coveo server, access the Administration Tool (see Opening the Administration Tool).

2. Select Configure > Connectors.

3. In the Connectors page, select the connector that you want to modify.

4. In the page for the connector:

   1. In the Option section, select or clear the Run in 64 bits check box when you want the connector to run respectively in a 64-bit or 32-bit process.

   2. Click Apply Changes.

   Note: You may need to restart the CES service to make changes effective (see Starting the CES Service).

5. Refresh all the sources for this connector (see Applying an Action to a Collection or a Source).
