How to recover application if application owner is deleted or blocked in API Store- WSO2 API Manager.

If you are trying to recover applications created by one user then we have a quick hack. We discussed how we can solve for APIM 1.9.0 and later versions in this(http://sanjeewamalalgoda.blogspot.com/2016/06/how-to-recover-application-if.html) post.

Now lets see how we can do same for APIM 1.8.0 as well.

• You need to create an user with application subscriber role using the Management Console or use an existing user which has application subscriber permissions.

• Below SQL statements needs to be run against the WSO2AM_DB

• Identify SUBSCRIBER_ID and USER_ID of both users (User who left the organization and the user that we are going to transfer application ownership) from AM_SUBSCRIBER table (eg: SELECT * FROM AM_SUBSCRIBER).

• Identify the application that needs ownership transferring from the AM_APPLICATION table
  (eg: SELECT * FROM AM_APPLICATION)

• Update the identified application's SUBSCRIBER_ID with the newly created user's SUBSCRIBER_ID from AM_APPLICATION table.
  (eg: UPDATE AM_APPLICATION SET SUBSCRIBER_ID=2 WHERE APPLICATION_ID=2)

• Update SUBSCRIBER_ID to new user's SUBSCRIBER_ID from the AM_APPLICATION_REGISTRATION (You need to identify entries that needs to be updated based on old user's SUBSCRIBER_ID)
  (eg: UPDATE AM_APPLICATION_REGISTRATION SET SUBSCRIBER_ID =2 WHERE REG_ID =1)

• Update AUTHZ_USER with the newly created user's USER_ID from IDN_OAUTH2_ACCESS_TOKEN table (You need to identify entries that needs to be updated based on old user's USER_ID)
  (eg: UPDATE IDN_OAUTH2_ACCESS_TOKEN SET AUTHZ_USER ='user2' WHERE ACCESS_TOKEN ='IhnmguiHsiDCFJFFwQugWZmUfdsa')

• Update USERNAME with newly created user's USER_ID from IDN_OAUTH_CONSUMER_APPS table (You need to identify entries that needs to be updated based on old user's USER_ID/USERNAME)
  (eg: UPDATE IDN_OAUTH_CONSUMER_APPS SET USERNAME='user2' WHERE CONSUMER_KEY='MjTy3lFFcy2FSdkjZnPBxjQwIGoa')

Note: In above examples, new user's SUBSCRIBER_ID=2 and USER_ID=user2

Please note that this is a hack and not a formal solution, We are providing above workaround believing you are having issues accessing applications where application owner has left the organization.
