Activating Transaction Logging on a Remote Server

Remote servers can use transaction logging to monitor data requests that the server receives from McIDAS-X clients. This information is written into the file SERVER.LOG, which resides in the first writable directory of the environment from which the server is run.

The following items are logged.

Transaction logging is activated by setting the environment variable ADDE_LOGGING in the remote server account before the server starts. Complete the steps below to do this automatically each time you log in to the remote server account.

1. Add the following line to the remote server account's $HOME/.mcenv file.

export ADDE_LOGGING;ADDE_LOGGING=YES

2. Examine the remote server account's $HOME/.profile file and add the following line if it's not already present. Be sure to leave a space between the period (.) and $HOME.

. $HOME/.mcenv

 

WARNING!
The SERVER.LOG file will continue to grow in size until it is truncated or removed. High access volume servers should schedule the file to be rotated or truncated to prevent filling of the file system.

To deactivate transaction logging, remove the line listed in step 1 above from the remote server account's $HOME/.mcenv file.
