# Source Override

Source Overrides are used to configure a PARCview client to connect to a data source differently than the default system setting.

**Location:** Location name of source to override.

**Source**: Source name that is being configured with an override address.

**Connection Type:** Defines how clients will connect to a data source.

**Remote UA Server:** Connect to source using a remote instance of UA Server specified in UA Server URI field. If field is blank, uses site’s primary UA Server.

**Direct Connection:** Connect to source directly using local PARCview client. Clients must be able to connect individually to the data source.

**HDA Server:** Connect to source using OPC HDA Server.

**Execution Environment:** Environment in which to execute data connection: inside or outside host process.

**In-Process:** Execute inside the host process. Host is determined by connection type: UA Server or PARCview client.

**Out of Process:** Launch a separate executable outside of host process.

**Out of Process on Mismatch:** If a source is configured with a direct connection type, attempt to execute in-process unless source connection platform does not match PARCview’s architecture. The most typical case would be attempting to connect to a data source using 32-bit dll’s or drivers from a 64-bit PARCview client.

**Out Of Process Exe Platform:** If either out of process execution environment is used, which platform type to use.

**Operating System Platform:** Use local OS system type platform.

**32 Bit:** Force using a 32 bit out of process executable.

**64 Bit:** Force using a 64 bit out of process executable.

**UA Server URI:** Address of Remote UA Server. If blank, uses site’s primary UA Server.

**Active:** Whether source override is enabled.
