Customer's tuxedo production environment database restart, the transaction business can automatically re-connect the database, query class business can not automatically reconnect. The difference between the two types of business is as follows:
Transaction business: tuxedo client in the following order: tpbegin tpcall tpcommit. Client tpcall server services, the service is called on the database dml operation.
Query service: The tuxedo client only executes the tpcall function. Client tpcall server service is called the service of the database select operation.
