SSSE System Requirements

SSSE is a part of the Siebel Enterprise. SSSE is composed of the following components:

  • Siebel Enterprise Server. Hosts one or more Siebel Servers that run the PIMSI Engine server component and the PIMSI Dispatcher server component, with the following characteristics:
    • For proper operation, only one instance of the PIMSI Dispatcher component can be run at a time in a Siebel Enterprise. However, you can run multiple instances of the PIMSI Engine component, either on a single Siebel Server or on multiple Siebel Servers.
    • A computer that hosts the PIMSI Engine component or the PIMSI Dispatcher component must use a supported operating system. For information about operating systems currently supported, see Siebel System Requirements and Supported Platforms on Oracle Technology Network.
    • The user account under which the Exchange Connector runs must have read-write privileges to the Microsoft Exchange mailboxes of all users who synchronize using SSSE. The Exchange Connector user must be in the same Active Directory forest as the users to be synchronized, or in a forest that has a trust relationship with the Active Directory forest of the users to be synchronized.

      The user names under which the PIMSI Engine and the DCOM Exchange Connector run must be in the same Active Directory forest, or in different forests that have a trust relationship, to communicate using Distributed Component Object Model (DCOM).

    • If your Siebel implementation experiences a shortage of connections to the database, increasing the number of PIMSI Engine components can sometimes resolve the problem. However, SSSE is only one kind of Siebel software that uses database connections. For more information about general management of database connections, see Siebel Performance Tuning Guide.

      NOTE:  The Siebel Bookshelf is available on Oracle Technology Network ( and Oracle Software Delivery Cloud. It might also be installed locally on your intranet or on a network location.

    • If your Siebel implementation uses Coordinated Universal Time (UTC) throughout, then SSSE automatically converts dates and times appropriately. If your Siebel implementation does not use UTC, then your Siebel Servers, Exchange Connector Host, Microsoft Exchange Servers, and Database Server must all be set to use the same time zone. For more information about using UTC, see Siebel Global Deployment Guide.
  • DCOM Exchange Connector Host. The computer on which the Siebel DCOM Exchange Connector software resides. The Exchange Connector computer can be a computer that is serving as part of the Siebel Enterprise Server or another computer that resides inside your organization's firewall.

PIMSI Engine works in conjunction with the Microsoft Exchange Server host, the computer that hosts the Microsoft Exchange Server software for Microsoft Outlook. There are no specific Siebel software requirements for the Microsoft Exchange Server computers. See your Microsoft documentation for system requirements.

NOTE:  If a Microsoft Exchange Server goes offline, remaining Microsoft Exchange Servers continue to synchronize SSSE users. When a Microsoft Exchange Server resumes operation, synchronization to that server resumes automatically.
