Reliable Connection Tab (OLE DB / ODBC Source System)

Context

The OLE DB source system and the ODBC source system only have a passive connection check since you use the database connected as the source system for the query process only.

PCo performs the connection check for these source systems only if a data query is received by PCo and no connection to the source system is open. In this case, PCo attempts to establish a connection. You can specify the number of connection attempts and the time between the individual attempts.

Procedure

  1. On the Plant Connectivity Management Console screen, select a source system and click on the Reliable Connection tab.
  2. For the information you need to enter, use the following table:

    Field

    Description

    Maximum Number of Retries

    Maximum number of connection attempts before the connection counts as failed. The default value is 3.

    If the attempt to establish a connection fails after the specified number of attempts, the agent instance switches to the Faulty state. In this case, an icon in the form of a red square with a white cross is displayed for the agent instance. See also: Remote Client

    Retry Interval (Seconds)

    Indicates the number of seconds before the next attempt.

    The default value is 30 seconds, meaning that the PCo system checks the connection every 30 seconds. If the agent instance establishes that there is no connection, the agent makes a new connection attempt every 30 seconds.
