10.1.2 Configuring the cman.ora file for the Oracle Connection Manager Host

You make changes to the cman.ora file manually. The following procedure describes how to set parameters in the cman.ora file:

1. Navigate to the cman.ora file in the ORACLE_BASE_HOME/network/admin directory.

   If the cman.ora file is not present in the ORACLE_BASE_HOME/network/admin directory, then look for the file in ORACLE_HOME/network/admin directory.

2. Open the cman.ora file with a text editor.
3. Configure the listening endpoint (ADDRESS).

   The listening endpoint specifies the protocol address for the Oracle Connection Manager listener. CMON, the Oracle Connection Manager monitoring process, uses this address to register information about gateway processes with the listener. The database uses the address to register service information at the Oracle Connection Manager node.

   The Oracle Connection Manager listener always listens on the TCP/IP protocol.

   (ADDRESS=(PROTOCOL=tcp)(HOST=proxysvr)(PORT=1521))

   Note:

   Oracle Connection Manager can connect to the database using protocols such as TCP/IP (version 4 and version 6). Starting with Oracle Database 12c release 2 (12.2), the TCPS protocol is also supported

4. Configure the access control rule list (RULE_LIST).

   The access control rule list specifies which connections are accepted, rejected, or dropped by the listener.

5. Configure the parameter list (PARAMETER_LIST).

   The parameter list sets attributes for an Oracle Connection Manager. Parameters take the following forms:

   • If global, then the parameter applies to all Oracle Connection Manager connections unless a rule-level parameter overrides it. To change a global parameter default setting, enter it into the PARAMETER_LIST with an allowable value.
   • If a rule-level parameter is enabled in the ACTION_LIST section of the RULE_LIST, then it applies only to connections specified by the rule. It overrides its global counterpart.
