Automated Package Loading
Release 11g R1 (11.1.1.7)
E40045-02
October 2013
This document provides an introduction to the Oracle Enterprise Data Quality (EDQ) autorun functionality, which allows EDQ to load projects and run jobs when the application server starts up. It explains how the system's autorun functionality is configured, introduces the chore types that can be performed by using the autorun facility and provides an example of an autorun script. The XML schema on which the autorun scripts are based is provided in full.
This document is intended for administrators responsible for configuring the automated execution of jobs. This document assumes that you are familiar with core EDQ concepts and can understand and write XML documents and schemas.
EDQ can be configured to perform a range of tasks when the application server starts up. Each task, which is composed of chores, can be configured to be performed every time the application server is started, or just once the next time the application server is started.
Autorun processing is controlled in EDQ by placing autorun scripts that specify tasks in one of two specific directories in the EDQ installation.
The EDQ autorun directory is found in the local configuration directory. It contains two subdirectories named onceonly and startup. When the application server starts up, EDQ checks the onceonly and startup directories for autorun scripts and processes any that are present.
Scripts in the startup directory are processed every time the EDQ application server starts up. Scripts in the onceonly directory are processed when the EDQ application server next starts up, and are then moved to the complete subdirectory within onceonly. Scripts in the complete directory are not processed on subsequent start ups.
Various kinds of autorun chores are available in EDQ, each with a set of attributes specific to its function. The chore types and their available attributes are defined by the autorun file XML schema, see The chores available are listed in the following table:
| Chore Type | What the Chore Does |
|---|---|
|
|
Downloads files from a web server. |
|
|
Loads a project from a |
|
|
Runs an existing job on the server. |
|
|
Runs a database script against the Director database. This kind of chore must only be used with extreme care, as inappropriately applied scripts may corrupt the underlying database. |
|
|
Waits for a specified interval before proceeding. |
Autorun scripts are files containing XML code. The main part of an autorun script consists of a list of chores, bounded by <chores> tags. Each chore is of one of the autorun chore types listed in "The Autorun Chores" and includes a set of attributes that specify the chore to be performed. The attributes available depend on the chore type selected.
The XML schema used to structure autorun scripts is given in full in
The following XML code shows a sample autorun script. The chores in this script instruct EDQ to:
Download the 23People.dxi file, overwriting any existing file with the same name.
Import the 23People project from the 23People.dxi file, overwriting any existing project with the same name.
Run the 23People Excel.23People job with the rp1 run profile. If this run profile specifies that the job is to run with a run label, it is run as a Server Console job using the runopsjob command and its published results are viewable in Server Console. Otherwise, the job is run as a Director job using the runjob command and its results are viewable only in Director.
<?xml version="1.0" encoding="UTF-8"?> <chores version="1"> <!-- Get the dxi file --> <httpget overwrite="true" todir="dxiland" tofile="23People.dxi"> <url>http://svn/repos/dev/trunk/benchmark/ benchmark/dxis/23People.dxi</url> </httpget> <!-- Import the project from the dxi --> <package direction="in" dir="dxiland" file="23People.dxi" overwrite="true"> <node type="project" name="23People"/> </package> <!-- Run the jobs --> <runjob project="23People" job="23People Excel.23People" runprofile="rp1" waitforcompletion="true"/> </chores>
This is the Autorun XML schema:
