The ECS can connect to two CMS computers (prime and backup) on the FOT/IMOC side. In order to change the CMS to which the ECS connects, the configuration needs to be changed and the ccommanding side of the ECS software needs to be restarted.
The new way for changing strings is in the file: Change Strings
The old way is:
The configuration files are in directory /home/ecs/ecs/ecs_config. The current working directory can be changed to this directory with command alias config. The relevant files are:
File | Explanation |
---|---|
CMS | The actual configuration file read by the ECS system upon software restart |
CMS.2 | Template file for connecting to the prime CMS (see the table above) |
CMS.1 | Template file for connecting to the backup CMS (see the table above) |
To change the configuration the contents of the file CMS needs to be changed. The easiest way to accomplish this is to copy the suitable template file to file CMS. The new configuration becomes effective after ECS software restart. The necessary steps (all taken in a soc terminal window) are hence:
