[mapserver-users] Parameterized MapFile using CGI variable

[Nicolas BOUTET]

Yes, I realize reading you that the include statement can be inserted at any
place in the main Map file.

So, it works !!!

 

Thanks a lot David

Nicolas, 

 

I didn’t have a mapfile that utilizes connection handy, but I did test using
INCLUDE to substitute the value for DATA in an individual layer.  

 

Here is part of the layer definition:

 

LAYER

  NAME "watersheds"

  STATUS DEFAULT

  #DATA 'majclip'

  INCLUDE "inc_data_majclip.map"

  TYPE POLYGON

 

The file inc_data_majclip.map contains:

 

  DATA "majclip"

 

Based on this, I would assume that you should be able to do the same with
the CONNECTION for each of your layers.

 

David.

Thank you David,

 

Yes, using INCLUDE should be a good solution. But as I know in MapServer
5.6, CONNECTION is a parameter of my LAYER objects, and not an object
itself. So I cannot have a CONNECTION object declared in a separate map
file
 And I prefer to not have to duplicate the layers in different map
files.

One potential way to do it would be with the use of ‘include’s.  

 

http://mapserver.org/mapfile/Include.html

 

The primary mapfile wouldn’t have a connection object, but it would contain:

 

INCLUDE “connect_info.map”

 

Then on each machine, you would have a different version of connect_info.map
that contained the correct connection object for that machine.  

 

This wouldn’t give you the flexibility of changing it through the CGI
interface, but would allow you to use the same exact mapfile on both
machines.  

 

David.

Dear All,

 

I have 2 MapServer servers. One for Production use, and the other for
Validation use.

The MAP files placed on those servers are similar except that each server
has a different Oracle database as datasource.

For now, I have some different CONNECTION values depending if the map file
is on the Production or on the Validation server. So finally I must have
different MAP files.

 

Is there a way to have exactly the same map files on the 2 servers, and to
use a variable to parameterize the CONNECTION.

 

For example, I would like to set the CONNECTION of my layers to
“%ORACLECONNECTIONSTRING%” and to set a CGI Environment variable named
ORACLECONNECTIONSTRING to the correct value on each server. 

 

Nicolas
