Cache Properties Files

Cache Properties Files


When developing business processes always develop with the mindset that your processes should operate in a generic fashion.� The way that you can avoid any hard coding values within a business process is to reference property cache files in your business process


Business Scenario

You have three environments DEV, QA, and PROD.� Each has a ftp framework bpml layer.� Your host ip address for connection to SIA are different for each environment.� How do you avoid hard coding these values so that you don't have to have a separate business process for each environment.


Create a ftp.cache.properties file in your properties folder/directory for each enviornment.� Enter cache values for each ftp.cache.properties file.


in ftpinfo.cache.properties in DEV


�in ftpinfo.cache.properties on QA


�In ftpinfo.cache.properties on PROD


Then in your bpml you use the sci-get-property () to retrieve the property value.

                                 <operation name="FTPBegin">
<participant name="FTPClientBeginSession"/>
<output message="FTPClientBeginSessionServiceTypeInputMessage">
<assign to="ConnectionRetries">3</assign>
<assign to="FTPClientAdapter">FTPClientAdapter</assign>
<assign to="RemoteHost" from="sci-get-property('ftpinfo.cache.properties','SIA_Host')"></assign>

Before you run your business process you have to refresh the cache pointing to your property file

                              <operation name="FTPCacheService">
<participant name="CacheRefreshService"/>
<output message="CacheRefreshServiceTypeInputMessage">
<assign to="cache_name">ftpinfo.cache.properties</assign>
<assign to="cache_type">properties</assign>
<assign to="." from="*"></assign>
<input message="inmsg">
<assign to="." from="*"></assign>
