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, one instance of the PIMSI Dispatcher component must serve your entire Siebel Enterprise. However, you can run multiple instances of the PIMSI Engine component, either on a single Siebel Server or on multiple Siebel Servers.
  • You can use SSSE in either clustered environments or nonclustered environments. Performance for SSSE in a clustered environment is roughly comparable to performance in a nonclustered environment that has multiple servers running the PIMSI Engine and the Siebel Exchange Connector components.
  • For optimum performance, it is recommended that you run the process-intensive PIMSI Dispatcher component on a machine that does not run the process-intensive PIMSI Engine component.
  • A machine 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 Siebel SupportWeb.
  • A machine that hosts the PIMSI Engine component must be in a domain that is a part of the same Active Directory forest (one or more Active Directory domains that share certain characteristics and information) as the Exchange Server.
  • 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.
  • 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, 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.
• Exchange Connector Host. Houses the Siebel Exchange Connector software. The machine that serves as the Exchange Connector Host must use a supported operating system. For information about operating systems currently supported, see Siebel System Requirements and Supported Platforms on Siebel SupportWeb. The Exchange Connector machine can be a machine that is serving as part of the Siebel Enterprise Server or another machine that resides inside your organization's firewall.

PIMSI Engine works in conjunction with the Microsoft Exchange Server host, the machine that hosts the Microsoft Exchange Server software for Microsoft Outlook. There are no specific Siebel software requirements for the Exchange Server machines, except that you locate them in a single Active Directory forest. See your Microsoft documentation for system requirements.

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