Siebel Administration Interview Questions and Explanation.
What is Siebel Native Load Balancer?
Its new in Siebel 7.7. A software component that provides load balancing.Scalability
- Allows Siebel to easily support very large numbers of concurrent users
- Can easily add additional servers.
- By distributing load to unused resources makes optimal use of available hardware.
- By distributing load to unused resources minimizes hardware bottlenecks.
- Without the maintenance overhead of Resonate
- Resonate Central Dispatch is no longer supported as of Siebel 7.7.
- If a load-balanced component becomes unavailable on one server, it can still be accessed through other load-balanced servers.
- Simple firewall configuration – 1 VIP/Vport only
- Allows change of port used (I.e. HTTP Tunneling)
- Round-robin through SWSE naming directory
- Load balance by number of running tasks of OM instances
- Listen to both static and configurable port
- Support SISNAPI reconnect out of box.
Siebel 3rd Party HTTP Load Balancer
- A hardware component that provides load balancing
- Allows Siebel to easily support very large numbers of concurrent users
- Can easily add additional servers
- By distributing load to unused resources makes optimal use of available hardware
- By distributing load to unused resources minimizes hardware bottlenecks
- If a load-balanced component becomes unavailable on one server, it can still be accessed through other load-balanced servers
- Simple firewall configuration – 1 VIP/Vport only
- Allows change of port used (I.e. HTTP Tunneling)
- Supports complex network technologies (I.e. NAT)
What is Siebel Connection Broker (SCBroker)?
Siebel Connection Broker is a server component. At least one instance of SC Broker must be running and by default it is always on.- Load balance is by least # of running tasks for all processes belong to a particular component
- Load balancing scheme is not configurable
- By default listens on static port 2321
Siebel Web Server Extension (SWSE)
- Siebel Web Server Extension (SWSE) is a plug-in that runs within the Siebel Web Server Interacts with Web server for all incoming and outgoing Web requests
- Direct requests via the Siebel Object Manager to the Siebel Web Engine. It handles all files with .SWE extension in the URL.
- Manages network connections to the application servers
- Requests a new network connection for each new user session
- Connection is generally persistent, until processes terminated at either end points or SISNAPI connection timeout
- Contains two layers
- Web framework layer –interacts with web client infrastructure
- Session manager layer – manages SISNAPI connections to the application server
- Siebel-Provided load balancing logic resides in the Session Manager layer
Siebel File System
- The Siebel File System consists of a shared directory that is network-accessible to the Siebel Server and contains the physical files used by Siebel clients. To gain access to files, web clients connect directly to the appropriate Siebel Server to request file uploads or downloads. The Siebel Server then accesses the Siebel File System using the File System Manager (FSM) server component. File System Manager will process these requests through interaction with the Siebel File System directory.
- When using Siebel Mobile Web Client in connected mode (also known as the Dedicated Web Client), you may want to connect directly to the Siebel File System without going through the File System Manager
Siebel Database
- The backend data store for Siebel Enterprise
- Customer Data
- Seed Data
Siebel Report Server
- Actuate Report Server
- Generates and manages reports
- Contains the Report Encyclopedia, which is a shared repository that stores report items along with related data, such as access privileges and request queues
- Actuate Active Portal
- Provides access to the Siebel Reports Server from the World Wide Web
- Allows users to access and work with reports through any web browser
- Actuate Management Console
- Offers the capability to manage one or more Actuate Report Server and Encyclopedia
- Siebel Report Server Access
- A Siebel integration component that includes Siebel Report executables, templates, and other Siebel-specific library files.
- Communication between Siebel Object Manager and Reports Server
- Pre Siebel 7.7: Report Server API
- Siebel 7.7: SOAP
- Clustering support in Siebel 7.7.
