This chapter provides
a concise reference for all extension node deployment issues. There
are two paths for extension nodes deployments, depending on the SAS
Enterprise Miner installation, Workstation or Client/Server.
Each extension node
consists of four files.
-
<extention_name>.sas7bcat
— SAS code for the extension node.
-
<extention_name>.xml —
Definition of the extension node for the graphical user interface.
-
<extention_name>_16.gif —
A small, 16–bit gif file that serves as the extension node’s
icon on the node toolbar.
-
<extention_name>_32.gif —
A large, 32–bit gif file that serves as the extension node’s
image in the diagram workspace.
The extension node files
must be available to the SAS Server. It is recommended you create
a folder accessible by everyone that will use the extension tool (for
example EMEXT). You must add the XML file to the extension node folder
and create two subdirectories in this folder named
gif16 and
gif32 to hold the 16- and 32-bit icons, respectively.
The SAS code for the
extension node must be available to the SAS server. It is recommended
that you put your code in catalog source entries. The path to the
SAS code is stored in the extensions.xml file. If you add the path
for your EMEXT folder to the SASHELP concatenation in the SAS system
configuration file, then the catalogs in the EMEXT folder will be found
by the server. Because the path to the SAS code is stored in the extensions.xml
file, when creating your own extension node that you will need to
edit your extensions.xml file to specify your catalog and source entry.
An example extension
node (EXT Demo) is part of SAS Enterprise Miner. See the SAS Help
for SAS Enterprise Miner for details about EXT Demo.
For client/server configurations,
the four files in the EXT Demo node are
-
SASHELP.EMUTIL.EXTDEMO.SOURCE
-
C:\Program Files\SASHome\SASEnterpriseMinerMidTier\7.1\Static\wars\sas.enterpriseminer.svcs\WEB-INF\classes\components\ExtDemo.xml
-
C:\Program Files\SASHome\SASEnterpriseMinerMidTier\7.1\Static\wars\sas.enterpriseminer.svcs\WEB-INF\classes\components\gif16\ExtDemo.gif
-
C:\Program Files\SASHome\SASEnterpriseMinerMidTier\7.1\Static\wars\sas.enterpriseminer.svcs\WEB-INF\classes\components\gif32\ExtDemo.gif
For workstation configurations,
the four files in the EXT Demo node are
-
SASHELP.EMUTIL.EXTDEMO.SOURCE
-
C:\Program Files\SASHome\SASEnterpriseMinerWorkstationConfiguration\7.1\WEB-INF\classes\components\ExtDemo.xml
-
C:\Program Files\SASHome\SASEnterpriseMinerWorkstationConfiguration\7.1\WEB-INF\classes\components\gif16\ExtDemo.gif
-
C:\Program Files\SASHome\SASEnterpriseMinerWorkstationConfiguration\7.1\WEB-INF\classes\components\gif32\ExtDemo.gif
