2 Oracle Connection Manager Control Utility

This chapter describes the commands and associated syntax of the Oracle Connection Manager Control utility.

This chapter contains the following topics:

Oracle Connection Manager Control Utility Overview

The Oracle Connection Manager Control utility enables you to administer Oracle Connection Managers. You can use its commands to perform basic management functions on one or more Oracle Connection Managers. Additionally, you can view and change parameter settings.

Command Modes and Syntax

The basic syntax of the Oracle Connection Manager Control utility is as follows:

cmctl command [argument]

You can use Oracle Connection Manager Control utility in command mode, or batch mode.

The Oracle Connection Manager Control utility supports four types of commands:

Note:

You can use SET commands to dynamically alter configuration parameters, the changes only remain in effect until the Oracle Connection Manager is shut down. You cannot save them to the cman.ora file. The one exception is the Oracle Connection Manager password, which you can save using the command SAVE_PASSWD.

Oracle Connection Manager Control Utility Commands

This section lists and describes the following commands for the Oracle Connection Manager Control utility:

ADMINISTER

Purpose

To select an Oracle Connection Manager instance.

Prerequisites

None

Syntax

From the Oracle Connection Manager Control utility:

CMCTL> ADMINISTER [-c] instance_name

Arguments

instance_name: The instance of Oracle Connection Manager that you would like to administer. Instances are defined in the cman.ora file.

Usage Notes

You can issue the ADMINISTER command only within the utility. You cannot issue the command from the operating system.

ADMINISTER enables you to choose an Oracle Connection Manager to administer. To start this Oracle Connection Manager, you must issue STARTUP.

When you omit the instance name from the command, the instance administered defaults to the local instance.

Use the -c option when you want to administer an instance that is not the local instance.

A password is required only if one was provided at installation time or during a previous session of the Oracle Connection Manager.

Example

CMCTL> ADMINISTER cman_indl040ad
Enter CMAN password: password
Current instance cman_indl040ad is already started
Connections refer to (address=(protocol=TCP)(host=indl040ad)(port=1560)).
The command completed successfully

CLOSE CONNECTIONS

Purpose

To terminate connections, using specific qualifiers to select connections.

Prerequisites

Oracle Connection Manager must be running.

Syntax

From the operating system:

cmctl CLOSE CONNECTIONS [in state] [gt time] [from source] [to destination]
[for service] [using gateway_process_id] [connect_identifier_list]
[-c cman_name]

From the Oracle Connection Manager Control utility:

CMCTL> CLOSE CONNECTIONS [in state] [gt time] [from source] [to destination] 
[for service] [using gateway_process_id] [connect_identifier_list]

Arguments

state: One of the following values to specify the connection state:

  • idle: Connections that are inactive in the established state

  • connecting: Connections that are in the process of connecting

  • established: Connections that are connected and are transferring data

  • terminating: Connections that are disconnecting

If no state is specified, then CLOSE CONNECTIONS defaults to all possible states. If the time qualifier is included under these conditions, then the time specified is the amount of time that has elapsed since a client initiated a connection.

time: The time format. Use the following format to specify connections greater than the time indicated:

gt[hh:mm:]ss

source: The source address. Use one of the following formats to specify the source address:

  • from IP

  • from hostname

  • from subnet

destination: The destination address. Use one of the following formats to specify the destination address:

  • to IP

  • to hostname

  • to subnet

service: The service name. Use the service_name parameter to specify the service, such as sales.us.example.com.

gateway_process_id: The gateway process identifier is a number. Use this number to specify connections that are proxied by the gateway process indicated. To determine the gateway process identifier, use the Oracle Connection Manager control utility show gateways command.

connect_identifier_list: The connection identifiers. Use a space between multiple connection identifiers in a list.

Usage Notes

Because the CLOSE CONNECTIONS command terminates connections, it might generate error messages on both client and server sides.

The IDLE state qualifier always requires a time qualifier.

Issuing CLOSE CONNECTIONS without an argument closes all connections.

Examples

The following example shuts down connections in any state. The elapsed time of the connection must be greater than 1 hour and 30 minutes. The connection source is the specified subnet, and the destination is the specified host name.

CMCTL>
 CLOSE CONNECTIONS gt 1:30:00 from 192.168.2.32/27 to host1

The following example shuts down those connections proxied by gateway process 0 that have been in the idle state more than 30 minutes:

CMCTL> CLOSE idle CONNECTIONS gt 30:00 using 0

The following example shuts down connections that are connected to the service sales.us.example.com:

CMCTL> CLOSE established CONNECTIONS for sales.us.example.com
