TM1 Server operations
This section describes how IBM®
TM1® servers work, and how you can manage their
operations.
The following diagram illustrates the operations of a TM1 Server.

- When the TM1 server is started, all TM1 data is loaded from the TM1 data directory into RAM on the server machine.
- While the TM1 server is running, all cube data resides in RAM. All edits received from TM1 clients are stored in a transaction log file named Tm1s.log.
- TM1 clients retrieve cube values from the server. Clients also send edits to cube values to the TM1 server.
- When the TM1 server is shut down, or when an explicit Save Data command is issued, any changes to cube values are written from the transactional log file to the data directory.
