2 Oracle Connection Manager Control Utility

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

This chapter contains these 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 choose between two command modes:

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

Note that while you can use SET commands to dynamically alter configuration parameters, these 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 by issuing the command SAVE_PASSWORD.

Distributed Operations

The Oracle Connection Manager Control utility can perform operations on a local or a remote Oracle Connection Manager. Note, however, that an instance must be started locally—that is, on the computer where the instance is located.

To set up one instance of Oracle Connection Manager to remotely administer another:

  1. Configure the tnsnames.ora file on the local computer to include the remote listening address. Assume, for instance, that the local Oracle Connection Manager is called cman1 and that it resides on proxysvr1. Assume, too, that the remote Oracle Connection Manager is called cman2 and that it resides on proxysvr2. The tnsnames.ora file on proxysvr1 would be configured this way:

    CMAN2=
      ((ADDRESS=(PROTOCOL=tcp)(HOST=proxysvr2)(PORT=1521)))
    
  1. In the cman.ora file on the remote computer, set the value of the parameter REMOTE_ADMIN to yes as in the following example:

    CMAN2=
      (CONFIGURATION=
        (ADDRESS=(PROTOCOL=tcp)(host=proxysvr2)(port=1521))
        (PARAMETER_LIST=
    
   (REMOTE_ADMIN=YES)))

Oracle Connection Manager Control Utility Commands

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

ADMINISTER

Purpose

Use the ADMINISTER command to choose an instance of Oracle Connection Manager.

Prerequisites

None.

Syntax

From the Oracle Connection Manager Control utility:

CMCTL> ADMINISTER instance_name using password

Arguments

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

[password]: Specify the password, if any, for this instance of Oracle Connection Manager.

Usage Notes

Issue ADMINISTER only in interactive mode. 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.

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

Example

CMCTL> ADMINISTER cman_indl040ad using jayu123
Current instance cman_indl040ad is already started
Connections refer to (address=(protocol=TCP)(host=indl040ad)(port=1560)).
The command completed successfully
CMCTL:cman_indl040ad>

CLOSE CONNECTIONS

Purpose

Use the CLOSE CONNECTIONS command 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][-p password]

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

[in state:] Use 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, CLOSE CONNECTIONS defaults to all possible states. If the time qualifier is included under these conditions, the time specified is the amount of time that has elapsed since a client initiated a connection.

[gt time:] Use the following format to specify connections greater than the time indicated:

gt[hh:mm:]ss

[from source]: Use one of the following formats to specify the source address:

  • from IP

  • from hostname

  • from subnet

[to destination]: Use one of the following formats to specify the destination address:

  • to IP

  • to hostname

  • to subnet

[for service]: Use the following format to request a service:

for service_name

[using gateway_process_id]: Use this format to specify connections that are proxied by the gateway process indicated.


[connect_identifier_list]: Space between multiple connection identifiers in a list.

Usage Notes

Because the CLOSE CONNECTIONS command aborts 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 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; the destination, the specified host name.

CMCTL:CMAN_user-sun.us.example.com>
 CLOSE CONNECTIONS gt 1:30:00 from 192.0.2.32/27 to host1

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

CMCTL:CMAN_user-sun.us.example.com> CLOSE idle CONNECTIONS gt 30:00 using 0

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

CMCTL:CMAN_user-sun.us.example.com> CLOSE established CONNECTIONS for sales.us.example.com

[gateway]: Enter the ID of the gateway or gateways whose status you want to display

Issuing SHOW GATEWAYS without an argument displays the status of all gateway processes.

Usage Notes

If you want to display multiple gateways, use a space to separate the ID numbers when entering the command.

Example

CMCTL:CMAN_user-sun.us.example.com> SHOW GATEWAYS 1
Gateway ID                     1
Gateway state                  READY
Number of active connections   0
Peak active connections        0
Total connections              0
Total connections refused      0
