Table 34: LOG-MANAGER system handle methods
Method Function
CLEAR-LOG( ) Clears all messages existing in the current client log file and
leaves the file open for writing
WRITE-MESSAGE( ) Writes user messages to the current log file
CLOSE-LOG( ) Stops an interactive or batch OpenEdge client from writing
messages to the current client log file and closes the log file
Note: The CLOSE-LOG( ) method is valid only for interactive and batch clients.
WebSpeed agents and AppServer servers write a message to the server log
file indicating that it is invalid to use the CLOSE-LOG( ) method to close a
WebSpeed or AppServer server log file. DataServer connections established
by Webspeed or AppServer agents all share the same server log file. So, you
cannot execute the CLOSE-LOG( ) method unless there is only one agent with
an open DataServer connection. In this case, the method returns FALSE.
For more information on the LOG-MANAGER system handle or its attributes and methods,
see the LOG-MANAGER system handle reference entry in OpenEdge Development: ABL
Reference.
DSLOG-MANAGER system handle attributes and methods
The DSLOG-MANAGER system handle is similar to the LOG-MANAGER system handle. Is is
used to control the logging settings for the server context of the OpenEdge DataServer
logging infrastructure, while the LOG-MANAGER controls logging settings for OpenEdge
Client and DataServer client context. Although both provide attributes and methods for
enabling, disabling, and changing logging capabilities, the DSLOG-MANAGER applies only
to DataServer components.
The DB-CONTEXT attribute must be set before any other DSLOG-MANAGER attribute can
be accessed.
