gasadmin tool

The gasadmin tool is provided as an administrative command for the Genero Application Server.

Links to examples of some of the more common uses of the tool are grouped under headings: manage sessions, GAS administration, GAS configuration, manage GAR files and clients, monitor web services:

Syntax

gasadmin { -V | -h | command [ options ] [ args ] }
  1. Display help or version information for the gasadmin command. Help is specific to commands and there is a help option for each command.
  2. command. There are various commands to administer the GAS:
    1. session administers application sessions.
    2. config handles GAS configuration.
    3. gar deploys and manages Genero archives (gar) files.
    4. gbc deploys and manages Genero Browser Clients (GBC) on the GAS.
    5. reset-log reconfigures the logs for sessions running on the GAS.
    6. monitoring monitors web service on the GAS. This command supports six commands:
      1. status gets monitoring configuration status.
      2. update sets the monitoring configuration.
      3. reset resets the monitoring configuration.
      4. fetch retrieves monitoring data stored in .dat files.
      5. clean removes monitoring data stored in .dat files.
      6. preload configures monitoring from commands stored in a file.
    7. send-message allows an administrator of the GAS to send messages to connected users on the specified applications and sessions, or to connected user on all sessions running in the GAS.
    8. list-sessions lists the active sessions.
    9. close-session closes the specified sessions gracefully.
    10. close-all-sessions closes all active sessions gracefully.

Session command examples

These examples show how you use the gasadmin command to work with sessions.

Example: List sessions

This example shows how to list all sessions running on the dispatcher.

The command is run on the admin port (TCP_ADMIN_PORT) used by the dispatcher for this purpose. With the option -f you can specify the configuration file where the port is set; otherwise, the default GAS configuration file is used. 
gasadmin session list-sessions

The output displays a list of the sessions. It includes the following details:

  • session identifier: identifies the GAS session for the application or web service. In the example, this is "96c9ce0ded72135ddf43ad421a2d87b9".
  • Name: represents the name of the application or web service running in the session.
  • Port: represents the port number the uaproxy or gwsproxy is using to communicate with the dispatcher (if UNIX sockets are used, the value is 0).
  • Type: identifies the type of session: "WebServices" or "UA Client" (application).
  • Pid: represents the pid of the uaproxy or gwsproxy.
  • GSID: represents the Genero session id used by web applications. In the example, this is "1a5569ed45193a6abd7a2e8e67199300". The GSID is used by the browser to keep track of the session of a web application. The value is stored in a cookie. GSID is not used by web services.
  • VM Pids: represents the fglrun processes the current uaproxy or gwsproxy has started.
In the sample, the list is output as text. This is the default. To output in JSON format, use the gasadmin list-sessions --output json command.

Example: List session ids

This example shows how to list just the identifiers of the sessions running on the dispatcher.

The command is run on the admin port (TCP_ADMIN_PORT) used by the dispatcher for this purpose. With the option -f you can specify the configuration file where the port is set; otherwise, the default GAS configuration file is used. 
gasadmin session list-session-ids
In the sample, the list is output as text. 
    Session list:
      - 784f51e41e5010db8bc201915fc95fe8
      - 906d0e5fc69b196f348fd85d371315cf
      - 1d5d88ddf6e2cbfdcd47791583e2c163
      - 03d7e82913d590a316fbeb4b1ded6624
In this example, the command is run in silent mode. 
gasadmin session list-session-ids --quiet
Just the list of session ids is output.

Example: Ping sessions

This example shows how to use -X -f options to ping all sessions of a specified GAS configuration file.

The command is run on the admin port (TCP_ADMIN_PORT) used by the dispatcher for this purpose. With the option -f you can specify the configuration file where the port is set; otherwise, the default GAS configuration file is used. 
gasadmin session -X -f as1.xcf
The GAS outputs the reply from all current sessions. The output displays the session id, which is a long string, for example, "96c9ce0ded72135ddf43ad421a2d87b9" with the name of the service or application in parenthesis. If the ping is successful, the reply from the dispatcher is OK.
Checking all sessions: (httpdispatch) Ping session
96c9ce0ded72135ddf43ad421a2d87b9 (demo/RestBook): OK Ping session dfd29c347ecf2d572aef95a13c6d4a04
          (_default/gwc-demo): OK

Example: Stop sessions

If you need to stop a session, you use the -k option of the gasadmin session command.

The command is run on the admin port (TCP_ADMIN_PORT) used by the dispatcher for this purpose. With the option -f you can specify the configuration file where the port is set; otherwise, the default GAS configuration file is used.

This action affects the specified session id, "d98290172c8f7c0d861db329f1ce6597" in the example. 
gasadmin session -k
          d98290172c8f7c0d861db329f1ce6597 -f as1.xcf
Tip:

You can use the -K option to terminate (kill) all active sessions.

Example: Close sessions

If you need to stop a session gracefully, use the gasadmin close-session to close a specified session or the gasadmin close-all-sessions to close all sessions.

The command is run on the admin port (TCP_ADMIN_PORT) used by the dispatcher for this purpose. With the option -f you can specify the configuration file where the port is set; otherwise, the default GAS configuration file is used.

In the following examples the close session action affects the specified session id, "d98290172c8f7c0d861db329f1ce6597". To get the session id, run the gasadmin session --list command.

You have the option of sending a message or an end URL to the user agents. If an end URL is specified, the user agents redirect to it on closing the session. The --message and --end-url options are mutually exclusive.
  • In this command a message is sent to display in the user agent on closing the session. The message will be displayed in the application ended page. The output shown in Figure 1 is intended as a sample to show the message displayed in the application ended page; the format may change in future product releases.
    gasadmin close-session --session d98290172c8f7c0d861db329f1ce6597 -f as1.xcf 
                                --message "closed"
    Figure: Application ended page with message


  • In this command a URL for redirection is sent to user agents on closing the session. 
    gasadmin close-session --session d98290172c8f7c0d861db329f1ce6597 -f as1.xcf 
                                --end-url "http://www.4js.com"

In the next examples the close session action affects the specified applications:

  • In this command a message is sent to display in the user agent on closing the application session. 
    gasadmin close-session --app mygroup/myapp -m "You have been disconnected"
  • In this connand a URL for redirection is sent to user agents on closing the application session. 
    gasadmin close-session --app mygroup/myapp -u "http://www.4js.com"

In the next examples the close-all-sessions action affects all sessions:

  • In this command a message is sent to display in the user agent on closing all session. 
    gasadmin close-all-sessions -m "You have been disconnected"
  • In this command a URL for redirection is sent to user agents on closing all sessions. 
    gasadmin close-all-sessions -u "http://www.4js.com"

Example: Cleanup session

This example shows you how to perform a cleanup on the GAS to remove temporary files or directories that may have been used during a session.

The command is run on the admin port (TCP_ADMIN_PORT) used by the dispatcher for this purpose.
gasadmin session --session-cleanup
This cleanup is performed automatically at dispatcher start up.

If your GAS version is prior to 3.10, you need to use the following command:

gasadmin --session-cleanup -d <dispatcher>

Example: Show dispatcher

The gasadmin session --whoami option provides information on the dispatcher.

The command is run on the admin port (TCP_ADMIN_PORT) used by the dispatcher for this purpose. With the option -f you can specify the configuration file where the port is set; otherwise, the default GAS configuration file is used. 

gasadmin session --whoami -f as1.xcf
The command will return the kind of dispatcher you are communicating with: httpdispatch, fastcgidispatch, or isapidispatch.

Example: Monitor session

This example shows how to use the gasadmin session --monitor option to retrieve information to monitor a specified session. Information on the current status of the dispatcher is sent to the standard output in XML format during the session. 
gasadmin session --monitor d98290172c8f7c0d861db329f1ce6597

If your GAS version is prior to 3.10, you need to use the following command:

gasadmin --dispatcher <dispatcher> --monitor <session-id>

Example: Idle session

The gasadmin session --idle-time session option is useful if you want to check on user activity for a given session. It gives you the number of seconds since last user activity. Based on this, for example, you can decide if a session that has had no user activity for some time, can be stopped.

In the example the idle time session action affects the specified session id, "de7b246d34b550020610f40bbcebe20d". 
gasadmin session --idle-time de7b246d34b550020610f40bbcebe20d
Information on the current idle status of the session is sent to the standard output. The number of seconds (496 in the example) is the time elapsed in seconds since the last user activity.
Idle time for session de7b246d34b550020610f40bbcebe20d: 496

Deploy with gar example

The gar command deploys Genero archives (gar) files.
Important:

If you start the dispatcher with the option (-E) to override the $(res.appdata.path) location, you must also override the resource when deploying applications with the gasadmin gar command, in order to deploy to the correct directory.

For example, specify the same option with both commands:
  • Starting the dispatcher:

    httpdispatch -E res.appdata.path=/work/tmp/gas/appdata

  • Deploying the application:

    gasadmin gar -E res.appdata.path=/work/tmp/gas/appdata --deploy-archive myapp.gar

Command options are described in gar options.

Config command examples

These examples show how you use the gasadmin config command to work with configuration files.

Example: Explode configuration file into an XML file

This example shows how you use the -t option of the gasadmin config command to explode the specified application configuration file and expand its resources and its parent's resources into an XML file.
gasadmin config -t demo/Card

Example: Explode configuration file into XML files

This example shows how you use the -r -t options to explode the specified application configuration file. This causes its resources and its parent resources to be replaced with real values. The result is output in separate XML files.
gasadmin config -r -t demo/Card

Example: Compress resources

This example shows how you compress the resources located in the specified paths.
gasadmin config -z
            $FGLASDIR/app,$FGLASDIR/services,$FGLASDIR/web,$$FGLASDIR/tpl

GBC command examples

These examples show how you use the gasadmin gbc command to manage GBC clients.

Example: Deploy GBC

This example uses the gasadmin gbc --deploy command to deploy a GBC client on the GAS.
gasadmin gbc --deploy c:\fjs\gbc-projects\gbc-4.01.02\archive\custA.zip

Example: Listing GBC clients and setting a default

These examples show how you can use gasadmin gbc command options to list the deployed GBC clients and set a default client on the GAS.

gasadmin gbc --list 
gasadmin gbc --default custB
Figure: List deployed GBC and set default

Image shows the result of the gasadmin commands to list deployed GBC and to set the default client

Reset-log command examples

These examples shows how you can use the gasadmin reset-log command to reconfigure the log output.

Example: Reset logs for session

gasadmin reset-log --output-type DAILYFILE --categories "ALL DEBUG" 1170f560ca4d03fd3aa4bbac75da97e9
The command resets logging for the specified session:
  • The --output-type option specifies the logs are sent to the daily log file.
  • The --categories option specifies the type of log messages to send; see CATEGORIES_FILTER to view the log type options.
The changes from this command only affect the specified session.
Tip:

You can specify multiple sessions by listing the session ids, separated by spaces.

For options not specified, such as --output-path, gasadmin tries to use the LOG configuration from the as.xcf. If not found in the as.xcf (for example, CONSOLE may not be configured in as.xcf), default values are used.

Example: Reset logs for dispatcher

gasadmin reset-log --output-type DAILYFILE --categories "ALL DEBUG" dispatcher
The command resets logging for the running dispatcher:
  • The --output-type option specifies the logs are sent to the daily log file.
  • The --categories option specifies the type of log messages to send; see CATEGORIES_FILTER to view the log type options.
These changes affect the running dispatcher.

Example: Display GAS version information

gasadmin -V
