Troubleshoot Transactions

Commands are unaffected by many communication or coordinator failures, but certain cases require user action.

• Communication Failure or Coordinator Failure and Restart During Global Transaction
  If internode communication (INC) fails or the coordinator fails or is shut down during a writer-initiated global transaction, transactions suspend and resume automatically if the INC is restored before a user-specified timeout expires.
• Coordinator Failover and Global Transactions
  If the coordinator fails over during a writer-initiated global transaction before a user-specified timeout expires, transactions suspend and resume automatically.
• Dynamic Collisions
  A dynamic collision occurs when a schema change is committed on a table, procedure, function, or view while a secondary server is querying the same object. The collision results from the TLV replay of shared IQ object schema updates.
