Automated electronic notification provides a way to easily alert the business application users of the change in the system status and to stay organized, informed and in-touch 24/7. Oracle ESS provides the ability to notify users of the status of submitted jobs, and the recipient information can be specified via the user interface 'Notification' tab for submitting job requests. Notifications will be sent upon the successful completion of a job, or when a job completes in an error or warning state.
ESS delivers the notifications to the relevant users using the Oracle SOA Suite User Messaging Service (UMS). The UMS Server orchestrates message flows and will route outbound messages from the ESS client application to the appropriate UMS driver. UMS Drivers support widely-adopted messaging protocols and can be integrated with existing infrastructures such as a corporate email servers or XMPP (Jabber) servers.
The ESS Notification post processing action is used to notify users as to the completion status of the request. The Subject and Body of these notifications are preset to standard messages so users will always get the same information - as to whether a request has succeeded or failed, regardless which job was run. Also, ESS does not force these notifications to be sent via Email - a user may configure their UMS preferences such that their default channel is SMS (or text message), Instant Messaging, etc.
There are two configuration settings that affect how ESS interacts with UMS. These are:
• NotificationServiceURL
• SAMLTokenPolicyURI
The NotificationServiceURL is of the form http://<host>:<port> and indicates the server where UMS is running. If this is not set correctly, or if the http:// prefix is missing, Notification will not succeed. The SAMLTokenPolicyURI is used if such security has been configured for the UMS server. Notification is designed to handle the case of a null SAMLTokenPolicyURI and continue accordingly in the assumption that the null value indicates no SAMLTokenPolicy is required.
These notification settings are part of the ESSAPP connections configuration. ESS specific connections.xml will contain token expressions which will get materialized with concrete data obtained from the adf-domain-config.xml at runtime. The domain wide configuration file adf-domain-config.xml will maintain all the ADF connection parameters in Metadata Services(MDS) repository, and provides a centralized way to update all connections information used in Fusion Applications.
ESS connections xml attribute values can be modified using Mbeans. The MBeans save the changes in MDS, and the values in MDS override the values in the actual connections.xml file. ESS script 'essAdfDomainConfig.sh' implemented using WLST provides command line options to modify the ESS connections.xml parameters created in the MDS repository (if there is a need to modify the UMS server url properties).
Some important points to note when submitting the job using the ESS Request Submission user interface:
1. Check User preference for the user/recipient is setup with notification
2. Make sure that submitter is specifying the username (not email address) of the recipient user that is in ldap in the UI notification tab.
3. Ensure that ESS hosting application where the job is running includes oracle.sdp.client library reference in weblogic-application.xml.
Please refer the official Oracle documentation for more details on ESS notification, UMS user preferences configuration and troubleshooting.
