ONAMES_hostname  

Example:  

names.server_name = valid_string

Purpose:  

Indicates the name of the directory to which trace files from a Names Server trace session are written.  

Default Value:  

platform specific  

Example:  

names.trace_directory = complete_directory_name

Purpose:  

Indicates the name of the output file from a Names Server trace session. The filename extension is always.trc.  

Default Value:  

names  

Example:  

names.trace_file = filename

Purpose:  

Enables internal mechanism to control tracing by function name.  

Default Value:  

FALSE  

Example:  

names.trace_func = false

Purpose:  

Indicates the level at which the Names Server is to be traced.  

Default Value:  

OFF  

Available Values  

• OFF - No trace output
• USER - User trace information
• ADMIN - Administration trace information
• SUPPORT - WorldWide Customer Support trace information

Example:  

names.trace_level = admin

Purpose:  

indicates whether each trace file has a unique name, allowing multiple trace files to coexist. If the value is set to ON, a process identifier is appended to the name of each trace file generated.  

Default Value:  

ON  

Example:  

names.trace_unique = on

Purpose:  

Specifies listening addresses for Oracle Connection Manager.  

Default Value:  

cman = (address=(protocol=tcp)(host=anyhost)(port=1600))

Example:  

cman=
   (address_list=
       (address= ...)
      [(address = ...)] 
    )

Purpose:  

Sets parameters related to the running of Oracle Connection Manager.  

Default Value:  

• MAXIMUM_RELAYS = 8
• LOG_LEVEL = 0
• TRACING = NO
• TRACE_DIRECTORY = <pathname>
• RELAY_STATISTICS = NO
• SHOW_TNS_INFO = NO
• USE_ASYNC_CALL = YES
• AUTHENTICATION_LEVEL = 0
• MAXIMUM_CONNECT_DATA = 1024
• ANSWER_TIMEOUT = 0

Available Values:  

• MAXIMUM_RELAYS = [0-10240]
• LOG_LEVEL = [0-4]
• TRACING = [YES, NO]
• TRACE_DIRECTORY = <pathname>
• RELAY_STATISTICS = [YES,NO]
• SHOW_TNS_INFO = [YES, NO]
• USE_ASYNC_CALL = [YES, NO]
• AUTHENTICATION_LEVEL = [0, 1]
• MAXIMUM_CONNECT_DATA = [257-4096]
• ANSWER_TIMEOUT = [0 to n]

Usage Notes:  

• MAXIMUM_RELAYS = determines the maximum number of concurrent connections allowed.
• LOG_LEVEL = determines the level of logging performed by the Connection Manager.
• TRACING = enables tracing on the Connection Manager.
• TRACE_DIRECTORY = indicates the location where trace information specific to the Connection Manager is written.
• RELAY_STATISTICS = instructs the Connection Manager to maintain statistics pertaining to relay I/O activities such as number of IN bytes, number of OUT bytes, number of IN packets, number of out packets.
• SHOW_TNS_INFO = instructs the Connection Manager to include TNS events in the log file.
• USE_ASYNC_CALL = instructs the Conenction Manager to use all asynchronous functions while in the answering, accepting, or calling phase of establishing a connection.

  NOTE: CMAN supports out-of-band breaks, it will forward it on to the server.

• AUTHENTICATION_LEVEL instructs the Connection Manager to reject connect requests that are not using Secure Network Services. Secure Network Services is part of the Advanced Networking Option.

Example:  

cman_profile =
   (parameter_list= 
      (maximum_relays=512)
      (log_level=1)
      (tracing=yes)
      (relay_statistics=yes)
      (show_tns_info=yes) (use_async_call=yes)             
      (authentication_level=0)
   )

Purpose:  

Sets the rules for the network access control portion of Oracle Connection Manager.  

Values:  

• SRC - Source host name or IP address (in dot notation) of session request
• DST - Destination server host name or IP address (in dot notation)
• SRV - Database server SID
• ACT - Accept or Reject incoming requests with the previous characteristics.

Usage Notes  

The wildcard for host name is the single character `x'. In the case of an IP address (d.d.d.d), you may wild card the individual d's with an `x'.  

Example:  

cman_rules=
  (rules_list=
      (rule=(src=hostname)(dst=hostname)(srv=sid)
      (act=accept)) 
      [(rule= ...)] 
   )

Purpose:  

Defines which nodes do not have validnode checking.  

Example:  

tcp.excluded_nodes= (hostname or tcp_address, ...)

Purpose:  

Defines which nodes have validnode checking.  

Example:  

tcp.invited_nodes= (hostname or tcp_address, ...)

Purpose:  

Restricts session access of clients to destinations with enabling host privilege.  

Default Value:  

NO  

Values:  

• YES
• NO

Example:  

tcp.validnode_checking = yes
