Oracle Connection Manager Control Utility

2 Oracle Connection Manager Control Utility

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

This chapter contains the following topics:

2.1 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.

2.2 Command Modes and Syntax

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

cmctl command [argument]

The Oracle Connection Manager Control utility supports the following types of commands:

Initialization and termination commands such as STARTUP and SHUTDOWN
Alter commands such as SET LOG_LEVEL and SET EVENT
Display commands, such as SHOW STATUS and SHOW RULES
Gateway commands such as SHOW GATEWAYS and RESUME GATEWAYS

Note:

You can use SET commands to dynamically alter configuration parameters. The changes only remain in effect until 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 .

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

Using command mode:
- From the Oracle Connection Manager Control utility:
  
  Enter cmctl at the command line to obtain the program prompt, and then issue the command:
```
cmctl
CMCTL> command
```
- From the operating system:
  
  Enter the entire command from the operating system command prompt:
```
cmctl [command] [argument1 . . . argumentN] [-c instance_name]
```
  Each command issued this way can have an Oracle Connection Manager instance name appended as an argument. If an Oracle Connection Manager instance name is not provided, then the default instance name is assumed. The default name is cman_hostname. You may be prompted for a password if one was set in a previous CMCTL session. Issuing commands from an Oracle Connection Manager Control utility session of Oracle Connection Manager requires that a password be entered once, at the beginning of the session, if one has been set.
  
  Caution:
  
  There is an option to specify the password on the command line. However, doing so exposes the password on the screen, and is a potential security risk. Oracle recommends not using the password option (-p) on the command line.
Using batch mode:

You can combine commands in a standard text file, and then run them as a sequence of commands. To run in batch mode, use the following syntax:
```
cmctl @input_file
```

2.3 Oracle Connection Manager Control Utility Commands

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

2.3.1 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 name 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 which Oracle Connection Manager instance to administer. To start the Oracle Connection Manager instance, you must issue the STARTUP command.

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

Use the -c option when 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

2.3.2 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 192.0.2.32/24 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
