Hyrax: BES Administrative Commands

BES Administration Commands

The general form for all of the HAI commands is as follows: Namespace: http://xml.opendap.org/ns/bes/admin/1.0#

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     ...
 </hai:BesAdminCmd>

Start

Example:

<hai:Start />

Starts the master beslistener process. If a beslistner is already running nothing will be done.

Request Example

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     <hai:Start />
 </hai:BesAdminCmd>

Response Example

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     <hai:OK/>
 </hai:BesAdminCmd>

<?xml version="1.0" encoding="UTF-8"?>
 <hai:ParseError xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">

 </hai:ParseError>

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BESError xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     message text
 </hai:BESError>

StopNow

Example:

<hai:StopNow/>

Stops all beslistener processes; does not wait for the current transmissions to complete

Request Example

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     <hai:StopNow/>
 </hai:BesAdminCmd>

Response Examples

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     <hai:OK/>
 </hai:BesAdminCmd>

Here are the two kinds of errors possible:

<?xml version="1.0" encoding="UTF-8"?>
 <hai:ParseError xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     message text
 </hai:ParseError>

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BESError xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     message text
 </hai:BESError>

GetConfig

Element form:

<hai:GetConfig />

Retrieves the BES configuration file.

Request Example

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     <hai:GetConfig />
 </hai:BesAdminCmd>

Response Example

<?xml version="1.0" encoding="ISO-8859-1"?>
<hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
    <hai:GetConfig module="bes.conf">
    ...
    </hai:GetConfig>

    <hai:GetConfig module="h4.conf">
    ...
    </hai:GetConfig>

    ...

</hai:BesAdminCmd>

SetConfig

Element form:

<hai:SetConfig module="module-name">
     ...Module Name Configuration Content...
</hai:SetConfig>

Note that module-name is actually any of the configuration files (bes.conf, h4.conf) and that while we use some conventions, a bes really has a collection of files that are all sourced to form the current configuration. So we're showing files and it's assumed that in most cases those roughly correspond to the main configuration file for the bes and smaller files specific to individual modules.

Request Example

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     <hai:SetConfig module="ncml_module">
     ...NcML Module Configuration Content...
     </hai:SetConfig>
 </hai:BesAdminCmd>

Response Example

Returns a status indicating what happened (Was the configuration accepted, was it valid, did the bes restart, etc)

TailLog

Use this to get a 'tail' of the BES log.

Element form:

<hai:TailLog lines="integer"/>

Note that the value zero (0) has the special meaning to get all of the lines in the log.

Request Example

<?xml version="1.0" encoding="UTF-8"?>
 <hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
     <hai:TailLog lines="200"/>
 </hai:BesAdminCmd>

Response Example

Element form:

<hai:BesLog/>

<?xml version="1.0" encoding="ISO-8859-1"?>
<hai:BesAdminCmd xmlns:hai="http://xml.opendap.org/ns/bes/admin/1.0#">
    <hai:BesLog>
