PH04503: APP FALLS INTO IRRECOVERABLE STATE AFTER DIRECT UPDATE FAILED

APAR status

• Closed as program error.

Error description

• Affected mobile development environments: iOS, Android
  Mobile Devices Operating Systems impacted: iOS, Android
  User roles impacted: User
  Distribution: Fix Central, DevCenter
  Versions affected: 8.0
  In a server farm/cluster environment, if a server node is shut
  down but the load balancer is still routing requests to that
  node, direct update will fail. And the app will enter an
  inrecoverable state. On iOS, the direct update progress will be
  stuck at 0%. On Android, the the direct update process seems to
  complete successfully, but after app reload, File Not Found
  Exception will be seen and the app needs to be reinstalled to
  recover from the unusable state.
  

Local fix

• - To reinstall the app.
  - Or stop routing requests to the stopped node.
  

Problem summary

  * USERS AFFECTED:                                              *
  * End users of Mobile First apps that have updates served      *
  * through Direct Update                                        *

  * PROBLEM DESCRIPTION:                                         *
  * When a direct update to an app fails in certain conditions,  *
  * the app assumes that an update of an incorrect size has been *
  * received and fails to complete the direct update rendering   *
  * the app in an irrecoverable state. On iOS the symptom is the *
  * app is stuck at 0% download, whereas on Android, the update  *
  * appears to go through successfully but fails to process the  *
  * downloaded update.                                           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *
  ****************************************************************
  

Problem conclusion

• This scenario of direct update data size 0 is identified and a
  failure callback is thrown to the app's code which in turn will
  throw a direct update failure message to the user.
