APAR status

• Closed as program error.

Error description

• Create a JVM custom property to disable node synchronization
  prior to executing a configuration save operation when doing a
  rollout via the Administrative Console.
  

Local fix

• NA
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server versions 8.5.5 and 9.0.              *
  ****************************************************************
  * PROBLEM DESCRIPTION: When a rollout update is initiated on   *
  *                      an application through the admin        *
  *                      console on a system with automatic      *
  *                      node synchronization still enabled,     *
  *                      an automatic synchronization may        *
  *                      occur before it is being disabled and   *
  *                      cause the application to be down.       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  While running a rollout update through the admin console, a
  save may be performed before the node synchronization is
  disabled. The save may cause an automatic synchronization to
  happen between a deployment manager and its nodes when the
  synchronization interval is reached and before the node
  synchronization is disabled. Since the synchronization
  includes the changes from the application update operation, it
  causes an outage of a customer's application.
  

Problem conclusion

• The code has been modified to allow the user to set the system
  property
  com.ibm.websphere.console.application.rolloutUpdate.disableAutoS
  ync on the deployment manager JVM which disables the node
  synchronization before the configuration save is performed.
  
  To enable the system property in Admin Console:
  
  System administration --> Deployment manager --> Java and
  Process Management --> Process definition --> Java Virtual
  Machine --> Custom properties
  
  Name :
  com.ibm.websphere.console.application.rolloutUpdate.disableAutoS
  ync
  
  Value : true
  
  The fix for this APAR is currently targeted for inclusion in
  fixpacks 8.5.5.15 and 9.0.0.10.  Please refer to the
