+# osb12c-xquery-warmup
+Recompile/warm-up any XQueries at runtime in the OSB 12c
+
+# What is it
+  - a simple application (packaged as EAR) deployed in OSB/WLS
+  - activated when the OSB starting or XQuery is/was deployed (or if something is/was changed in XQuery and session is/was activated)
+  - pre-compile/execute Xquery with dummy arguments - warm-up 
+
+# Install
+  - Download latest version of application...
+  - Deploy it as enterprise application: _'Install this deployment as an application'_
+  - Deployment Order: 20
+  - Restart the OSB.
+
+# Development
+  - Build is based on the Maven
+  - JVM 1.8
+  - in pom.xml change path for following properties:
+| Plugin | README |
+| wls12cHome | path to FMW WLS 12c home |
+| osb12cHome | path to FMW OSB 12c home |
+| common12cHome | path to FMW 12c Oracle Common home |
+  - mvn clean install
