The following questions should be considered before determining which networking environment you will use for creating and maintaining a database link between sites.

Will the Smart P&ID connected Workshare collaboration need share-level access to update or synchronize plant and reference data files?

  • If share-level access is used to update or synchronize plant and reference data for a company-internal plant between two or more company locations, then a corporate WAN connection for this process is recommended.

  • If the connected Workshare collaboration is between different companies, a DMZ environment is a better solution. If a DMZ solution is used, performing a manual update of the plant and reference data will be required as share-level access in a DMZ environment is not recommended.

What are the corporate firewall policies for customers or vendors that need access to data inside your corporate LAN?

  • If customer or vendor access is not a possible solution for access to data inside your corporate firewall, a DMZ environment is the recommended solution.

What if I have a secure VPN established between my location and the satellite location for a connected Workshare collaboration?

  • If this environment is available, then we recommend share-level access for project and reference data updates and synchronization.

What ports need to be open for database access in a DMZ environment?

  • Port 1521 needs to be opened between the database servers at each location if the databases are using USE_SHARED_SOCKET to lock Oracle into using the single port for operation.

  • If USE_SHARED_SOCKET is not used, then all ports between the two locations must be open because Oracle uses random ports to communicate after the initial connection.

  • If both locations use Oracle Enterprise Edition, you can use Connection Manager to handle port connection between the databases at each location.
