16.6.5 About the Logging Parameters

Parameters that control logging, including the type and amount of information logged, and the location where the files are stored, are set in the configuration file of each network component.

Table 16-11 Location of Log Parameters

Network Component	Configuration File
Oracle Connection Manager processes	cman.ora
Listener	listener.ora
Client	sqlnet.ora
Database server	sqlnet.ora

Note:

If the ADR_ENABLED parameter is set to ON, then all logging parameters are set by ADR. Using Oracle Net Manager to change the parameters will not work.

• sqlnet.ora Log Parameters
