Configuration Modification

There are a number of parameters that can be modified for the query components.   Most are set to a default value which will typically suffice, but occasionally one might need to be customized.  For example there is a configuration parameter that controls the maximum number of rows that can be returned by a query.  This parameter is Queries.SetSize.Maximum   and is set to a default value of 500000.  Another parameter determines whether or not a warning dialog is displayed when a filter is deleted.  This parameter is DeleteFilterWarningDialogEnabled and is set to a default value of true.

To set these configuration parameter values, the file "Configuration.properties" must appear to be in the com\sas\query package.   This could be done by modifying the jar or zip file from which you are getting the query components. There is an empty version of this file in the queryAF.jar file that ships with webAF. For this example we will assume you are on a windows machine and have chosen to set some configuration values in this file. 

In this example we'll shut off the warning message when deleting a Filter.  We'll want to set the value of DeleteFilterWarningDialogEnabled to be false.

In the text file we specify the name of the parameter, follow it directly with an equal sign, and then the value we wish to assign to that parameter.  For boolean values you may specify true or false. For numeric values, just specify the number (no separating commas/periods).  String values do not need to be surrounded by quotes.

We'll open the jar file we are getting the query components from (open queryAF.jar with winzip). In the list of files contained in the jar we see Configuration.properties listed in the com/sas/query directory. Open this one file from the jar.

So if we wish to shut off those warning messages when we delete a filter we would put:
    DeleteFilterWarningDialogEnabled=false
in the Configuration.properties file. Similarly if we want to increase the maximum number of rows that can be returned in our queries we would add the line:
    Queries.SetSize.Maximum=500000
to Configuration.Properties. 

We now save the file and update the jar file with the new file. When you next run the query components, the warning message will not be shows when deleting filters.

Note: These configuration parameters can change in the future.  Some values that you may wish to modify are listed below, together with their default values.
