WebtoB Administration

WebtoB provides management functions such as status monitoring and system control. For example, system environment configuration can be accessed and modified dynamically without restarting the system. It also provides service-specific statistical data such as the total number of processed requests, average processing time, number of requests in the queue, etc.

WebtoB provides the aforementioned functions through the console management program wsadmin and the web program WebAdmin. This chapter describes the programs and commands provided for WebtoB administration.

1. wsadmin Console Management Program

wsadmin provides a text-based management environment. wsadmin waits in the command prompt and executes a command that has been entered.

wsadmin is executed as follows:

$ wsadmin

After wsadmin has been executed, the following message is displayed at the prompt to show that wsadmin is running.

--- Welcome to WebtoB Admin (Type "quit" to leave) ---

      When no tasks are being processed, 'NONE' is printed. If no task has been started while the thread was woken up, the status is 'RUN', and the task type is 'NONE'.

1.3. Suspend and Resume Server Processes

1.3.1. suspend (sp)

Suspends currently running server process’s activities. When a server process is suspended, it finishes its current task and then enters an idle state. Services in queue are left untouched and new service requests are pooled into the queue.

If service is interrupted due to a server application error, the server process must be suspended. Suspending a server process is useful when it is impossible to process a request due to an unknown error and additional work is required.

  • Usage

    > suspend [-v server name]
    Option Description

    [-v server name]

    Suspends the specified server.

  • Example

    The following is an example of suspending a PHP server. Check the server status with st-v to check that the status has been changed to BLK.

    $$1 webtob (wsadm) [2016-02-03T15:56:57]: suspend -v php
    Server(php) is supended
    $$2 webtob (wsadm) [2016-02-03T15:57:07]: st -v
    
    ------------------------------------------------------------------------------------------
     hth   svrname (svri)   status      reqs     count cqcnt    aqcnt qpcnt emcnt rscnt rbcnt
    ------------------------------------------------------------------------------------------
       ...
       0  php        (  3)   BLK         539       539     0      403     0     0     0     0
       ...

1.3.2. resume (rs)

Resumes a server process suspended by suspend. A resumed server process starts processing services in the queue and goes into the RDY state.

  • Usage

    > resume [-v server name]
    Option Description

    [-v server name]

    Resumes the specified server ready to processing requests.

  • Example

    The following is an example of resuming a suspended PHP server. Use the command st-v to check that the status has been changed to RDY.

    $$3 webtob (wsadm) [2016-02-03T15:57:27]: st -v resume -v php
    Server(php) is resumed
    $$4 webtob (wsadm) [2016-02-03T15:57:37]: st -v
    ------------------------------------------------------------------------------------------
     hth   svrname (svri)   status      reqs     count cqcnt    aqcnt qpcnt emcnt rscnt rbcnt
    ------------------------------------------------------------------------------------------
       ...
       0  php        (  3)   RDY         539       539     0      403     0     0     0     0
       ...

1.4. Queue Purge

1.4.1. qpurge (qp)

A large number of requests can fill server queues, cause delays, and create difficulties with servicing queued requests. The queue purge command can clear these queues to keep the system robust. This feature is useful for banks or public offices where hundreds of thousands of requests are processed each day. Deleted applications can be processed again at the client’s request. WebtoB manages separate queues for each server process. The administrator tool can clear queues individually to remove bottlenecks in the system. Per-application processing is possible, helping other applications to process effectively.

A service that is deleted by qpurge sends an error as follows:

503 Service Temporarily Unavailable.
  • Usage

    > qpurge [-v server name]
    Option Description

    [-v server name]

    Deletes the requests in the specified server queue.

  • Example

    The following is an example of deleting requests in a PHP server queue. Purged_count displays number of requests deleted.

    $$11 webtob (wsadm) [2016-02-03T15:58:52]: qpurge -v php
    q for svr php is purged: purged_count = 6

1.5. Dynamic Configuration Change

1.5.1. set

This command can dynamically modify values in the configuration file. Not every variable can be modified dynamically so check the list of available variables using the cfg command in wsadmin.

  • Usage

    > set [-n NODE name][-vh VHOST name][-g SVRGROUP name][-v SERVER name][-s SERVICE name]
    Option Description

    [-n NODE name]

    Configures the NODE section.

    [-vh VHOST name]

    Configures the specified VHOST section.

    [-g SVRGROUP name]

    Configures the specified server group.

    [-v SERVER name]

    Configures the specified server.

    [-s SERVICE name]

    Configures the specified service.

  • Example

    The following is an example of checking the MaxQCount value by using cfg -v php and changing its value by using the set command. After executing the set command, the MaxQCount value is changed to 100.

    $$10 webtob (wsadm) [2016-02-03T16:01:32]: cfg -v php
        SERVER(3): Name = php,
             SvgName = phpg,
             MinProc = 10,
             MaxProc = 10,
             MaxQCount(mq) = 0,
             ...
    $$11 webtob (wsadm) [2016-02-03T16:01:42]: set -v php mq 100
    new value (100) is set for section = SERVER, name = php, fld = mq
    $$12 webtob (wsadm) [2016-02-03T16:01:52]: cfg -v php
        SERVER(3): Name = php,
             SvgName = phpg,
             MinProc = 10,
             MaxProc = 10,
             MaxQCount(mq) = 100,
             ...

1.6. Client Disconnection

1.6.1. discon (ds)

A client connection that is currently connected or idle can be forcibly disconnected. First use the ci command to obtain client information and then use the discon command.

  • Usage

    > discon [-h HTH number] -a | -i idle time | -c Client ID [-f]
    Option Description

    [-h HTH number]

    Disconnects clients that are connected to a specified HTH.

    -a

    Disconnects all clients that are connected to HTHs.

    -i idle time

    Disconnects clients that exceed the specified amount of time (unit: second).

    -c Client ID

    Disconnects specified clients (client ID displayed by ci).

    [-f]

    Disconnects a connection immediately.

  • Example

    The following is an example of checking a client ID by using the ci command and then disconnecting the client 15 forcibly by using discon command.

    $$16 webtob (wsadm) [2016-02-03T16:02:42]: ci
    HTH   0:   RDY
    --------------------------------------------------------------------------------
     no   status count idle    local_ipaddr:port    remote_ipaddr:port  spri   user

1.7.4. logstart (logs), logend (loge)

Records executed commands and outputs to log files. A log file is created in the current directory.

From the log data, peak service time, unnecessary server process, and queueing status can be checked to analyze the overall system. The logstart command starts logging and the logend command stops logging.

  • Usage

    > logstart (logs)
    > logend (loge)

3. Commands

The following are commands provided by WebtoB.

Option Description

wscfl

Compiles the text WebtoB environment file and creates wsconfig (binary WebtoB environment file).

wsuncfl

Inversely converts the compiled wsconfig (binary WebtoB environment file) to a text environment file.

wsgst

Refers to the binary WebtoB environment file and creates a service table.

wsracd

Supports WebAdmin.

wsboot

Executes all or part of the WebtoB system.

wsdown

Terminates all or part of the WebtoB system.

3.1. wscfl

wscfl compiles the text type WebtoB environment file and creates wsconfig (binary WebtoB environment file). wscfl can be used on an operating system that WebtoB system is installed on.

If an error occurs while compiling the input file, the binary WebtoB environment file is not created and compilation stops. The WebtoB environment file made by this command is used in wsboot, and wsdown.

  • Usage

    wscfl -i text WebtoB environment file name [-o binary WebtoB environment file name][-b][-v]
    Option Description

    -i text WebtoB environment file name

    Compiles the target environment file. Used to specify a text based WebtoB environment file name. It is a required option.

    A path can be specified. If the specified environment file is not found, an error message is displayed.

    [-o binary WebtoB environment file name]

    Used to specify the binary WebtoB environment file name.

    Specifying a path is optional. If a path is not specified, the file is created in the current wscfl working directory.

    If omitted, the file name is set to "wsconfig" by default.

    [-b]

    Backs up the WebtoB environment file.

    [-v]

    Checks the WebtoB version.

  • Example

    • Using [-i] option

      The following is an example of creating the binary environment file, wsconfig, in the current directory by compiling http.m, a text type WebtoB environment file.

      $ wscfl -i http.m

      The following is an example of creating the binary environment file, wsconfig2, in the current directory by compiling http.m.

      $wscfl -i http.m -o wsconfig2
    • Using [-v] option

      The following is an example of checking the WebtoB version.

      $wscfl -v

3.2. wsuncfl

wsuncfl inversely converts the compiled wsconfig (binary WebtoB environment file) into a readable text, environment file. wsuncfl can be used on the operating system where WebtoB is installed.

When the original environment file is missing and only the binary file exists, the original environment file can be restored using wsuncfl.

  • Usage

    $ wsuncfl [-i binary WebtoB environment file name] [-o text WebtoB environment file name] [-v]
    Option Description

    [-i binary WebtoB environment file name]

    Binary environment input file to decompile. Specifying a path is optional. If the specified file is not found, an error message is displayed.

    If omitted, the file name is set to "wsconfig".

    [-o text WebtoB environment file name]

    Decompiled Text WebtoB environment file name.

    Required. Specifying a path is optional. If a path is not specified, the file is created in the current wscfl working directory.

    [-v]

    Checks the WebtoB version.

  • Example

    The following is an example of decompiling a binary environment file (wsconfig) into a text environment file (sample_r.m) in the current directory.

    $ wsuncfl –o sample_r.m

3.3. wsgst

wsgst refers to the binary WebtoB environment file and creates a service table. wsgst can be used on the operating system where WebtoB is installed.

wsgst refers to the SERVER and SERVICE sections in the binary WebtoB environment file made by the wscfl command. wsgst also creates a service table for each server. The table is a list of services provided by the server process. The table is compiled when the server program is being compiled. The table is used to find service locations while the server process computes.

"<server name>_svctab.c", the output of the wsgst command, is created in the directory 'svct' under the directory specified by WEBTOBDIR. The server name is specified in the SERVER section. The contents of each file is the service name provided by the server specified in the SERVICE section.

The services specified in the WebtoB environment file must also be specified in the service table of the server. I.e., if the server name, the service name, or the service’s SVRNAME is changed in the SERVER or SERVICE section of the WebtoB environment file, the server program must be recompiled with the service table.

  • Usage

    $ wsgst [-f binary WebtoB environment file name]
    Option Description

    [-f binary WebtoB environment file name]

    Used to specify the binary WebtoB environment file that is referred to.

    The result of the wscfl command is referred to by wsboot and wsdown.

    Specifying a path is optional. If the option is omitted, the output file is named "wsconfig" by default.

  • Example

    The following is an example of creating a service table by referring to wsconfig that is located in the config directory under the directory specified by WEBTOBDIR.

    $ wsgst

    The following is an example of creating service tables by servers by referring to the wsconfig2 environment file in the /user1/park/WebtoB/bin directory.

    $ wsgst -f /user1/park/webtob/config/wsconfig2

    For example, if an environment file is registered (shown in the following), a service table named webaps_svctab.c is created in the /user1/park/webtob/svct directory.

    ...
    *SERVER
    webaps         SVGNAME=webapsg
    
    *SERVICE
    svc1           SVRNAME=webaps
    svc2           SVRNAME=webaps
                           ...

3.4. wsracd

wsracd must be started before starting WebAdmin or SysMaster. wsracd can be used on an OS with WebtoB system installed (WebAdmin support is planned for future releases).

  • Usage

    $ wsracd [-k] [-f binary WebtoB environment file name] [-a] [-d]
    Option Description

    [-k]

    Option to not use the binary WebtoB environment file. If set, the default port is used instead.

    If the WEBTOB_RAC_PORT is set, its value is used as the port (wsracd usually uses this option).

    [-f binary WebtoB environment file name]

    Executes with the port set in the user specified binary WebtoB environment file.

    [-a]

    Executes in the anonymous (no authentication) mode.

    If omitted, authentication is required to connect to wsracd using an OS account. To use the OS account, ${WEBTOBDIR}/bin/wsracd must be changed to the root account and the sticky bit must be set.

    [-d]

    Execute in the debug mode.

  • Example

    The following is an example of executing wsracd with the binary WebtoB environment file. If no option is specified, ${WEBTOBDIR}/config/wsconfig is used by default. If wsconfig file does not exist, an error message is displayed.

    $ wsracd -a

    The following is an example of using the options specified with wsboot to execute wsracd.

    $ wsracd –k

    The following is an example of using the specified binary file '/user1/park/webtob/config/wsconfig2’to execute wsracd.

    $ wsracd –f /user1/park/webtob/config/wsconfig2

3.5. wsmkppd

wsmkppd is used to set the PassPhraseDialog item of the SSL(PROXY_SSL) section.

WebtoB prompts for the password at startup if an encrypted private key is set in the SSL(PROXY_SSL) section. To avoid having to enter the password at startup, set the PassPhraseDialog item. wsmkppd creates a passphrase file that stores the passphrase to apply to the PassPhraseDialog. For information about using the PassPhraseDialog, refer to SSL Section and PROXY_SSL Section.

  • Usage

    $ wsmkppd [-p passwd] ppd_filename sslname
    Option Description

    [-p passwd]

    Password for the encrypted private key.

    ppd_filename

    Name of the file that stores the wsmkppd execution results, which will be applied to the PassPhraseDialog item.

    sslname

    Name set in SSL(PROXY_SSL).

  • Example

    wsmkppd prompts for the password if it is not supplied using the -p option.

    • The following is an example of calling wsmkppd without any options.

      $ wsmkppd
      Usage: wsmkppd [-p passwd] ppd_filename sslname
               -p passwd: password of private key.
               ppd_filename: output file for PassPhraseDialog.
               sslname: name of SSL(PROXY_SSL) section.
    • The following is an example of executing wsmkppd with the ppd_filename and sslname options.

      $ wsmkppd ssl.ppd ssl1
      New password: (Enter password)
      Confirm: (Re-enter password)
      Adding Password for ssl1
      
      $ls -al ssl.ppd
      -rw-------  1 webtob webtob 19 Feb 19 10:33 ssl.ppd
    • The following is an example of executing wsmkppd with the -p option and 'mypasswd'. If ppd_filename already exists, the specified password is added to the existing file.

      $ wsmkppd -p mypasswd ssl.ppd ssl2
      Adding Password for ssl2
      
      $ls -al ssl.ppd
      -rw-------  1 webtob webtob 42 Feb 19 10:42 ssl.ppd
    • The following is an example of the result file created by executing wsmkppd.

      $ cat ssl.ppd
      ssl1:gJDP+OmN+wI=:
      ssl2:8eG+iZjNiu5k:

      The following is an example of an SSL section settings.

      *SSL
      ssl1          CertificateFile = "/webtob/ssl/newcert.pem",
                    CertificateKeyFile = "/webtob/ssl/newcert.pem",
                    PassPhraseDialog = "file:/webtob/ssl/ssl.ppd"
