What is Max MT server and min MT serve

Question

Hi All,
What is Max MT server and Min MT server means in Siebel?
Why we need to use this.?
Please give me some idea on this

Answer 1

Here's an excerpt:
Our basic recommendation is to have 20 tasks per MT Server. (An MT (Multi-Threaded) Server is equivalent to an operating system process.)
Consider the projected number of concurrent users for the application in the design phase of the implementation. Even though there may be a large number of potential users, a smaller number will be logged in at any given time. For purposes of the following discussion, assume that there are 100-200 concurrent users.
There are many variables to consider when tuning an Object Manager. This tuning should be reviewed with Siebel Expert Services as part of the Production Readiness review. Here are some variables to consider.
The number of concurrent users.
The length of time each user spends on the system during a session.
Session timeout.
Use of scripts.
Complexity of the application.
High usage times. (80% of users are online from 11:00 to 3:00)
The settings used for this Siebel Object Manager component are as follows:
Maximum Tasks = 300
Maximum MT Servers = 15
Minimum MT Servers = 5
Maximum Tasks represents the total number of concurrent users. Since the anticipated number of concurrent users is between 100-200 the setting has been set to allow for some extra breathing room. This is important to allow for sessions that do not log out properly and therefore hang around until the session timeout is reached. Session timeout can be set in the Webserver and is usually defaulted to 20 minutes.
Maximum MT Servers is the total number of processes that can be run for this component. It is also used to calculate how many tasks can be run on each process. The calculation is as follows:
Maximum Tasks / Maximum MT Servers = Number of tasks per MT Server
300 / 15 = 20
As mentioned before, our basic recommendation is that the ratio of Maximum Tasks to Maximum MT Servers be 20. An extensively configured or scripted application may require a lower ratio.
Minimum MT Servers is only used when the Siebel Server or the Component is started. This determines how many processes to startup for this component. The only benefit that this provides is that it reduces the initialization time of the process when a new MT Server is needed. In this example, 5 MT Servers were used because 100 users are anticipated. This way the system can handle 100 concurrent users before having to startup a new process.
