Add subscriptions to a collection

Similarly, the user can add a subscription to that collection and its immediate child resources by selecting the option Collection and Children only or to that collection and all of its child resources by selecting the option Collection, Children and Grand Children.

E-mail notifications 

1. To enable sending email notifications, configure the mail transport in the axis2.xml file at <GREG_HOME>/repository/conf/axis2. 
2. You have to provide a valid email address to receive notifications from the subscribed resource. 
   

3. When a subscription is added initially, a verification email is sent to the user. When the user clicks the verification URL, the server console opens in a different tab prompting a successfully verified message.

   Info

   One Time Email Verification When adding subscriptions to different resources defining the same email address as the notification method, for each subscription users receive a verification email with a link to verify the subscription. The subscription gets active only if the user clicks the verification URL. However, if the user starts the server as ./wso2server.sh -Donetime.email.verification=true  the email verification only happens once when the particular email address is used for first time. Changing Host Name of URLs in Verification/Notification E-mails To change the Host Name of URLs appearing in Verification and Notification e-mails, set the HostName attribute in repository/conf/carbon.xml.

4. Whenever an event occurs which is in accordance with the subscription type, the user recieves notification emails.

1. When using the Management Console notification method, the roles of users are subscribed to events of resources. Notifications are displayed on the worklist tab at the top. The number of notifications received are shown on the tab and when the tab is clicked the list of notifications is displayed.
   
   
2. To enable this notification method, it is necessary to add WorkList configuration to the registry.xml file at the <GREG_HOME>/repository/conf directory. Please refer to this page to enable WorkList configurations.
   
3. Once all the options are specified, click the Subscribe button.

Configuring subscriptions to a mounted setup

Follows the steps below to configure a registry based subscription with the mounted setup:

1. In the <GREG_HOME>/repository/conf/carbon.xml file, define the host name. For example,
   
   <HostName>governance.wso2.com</HostName> 

2. Update the host name in the <GREG_HOME>/repository/conf/registry.xml file as well. For example,
   
   

   Code Block
   language xml
   <remoteInstance url="https://governance.wso2.com:9443/registry"> <id>instanceid</id> <dbConfig>mounted_registry</dbConfig> <readOnly>false</readOnly> <enableCache>true</enableCache> <registryRoot>/</registryRoot> <cacheId>root@jdbc:mysql://localhost:3306/greg_db</cacheId> </remoteInstance>

    

   Info
   Note: In the above example, the host name is governance.wso2.com and the WSO2 Governance Registry server is running on the default port (without any port offset). If you have configured a port offset, update the 9443 port above accordingly.

List added subscriptions

When a new subscription is added it is displayed on the Notifications list.
