It is possible to stop the creation of new transactions at any time by calling method TxControl.disable. Transactions that are currently executing will not be affected. By default recovery will be allowed to continue and the transaction system will still be available to manage recovery requests from other instances in a distributed environment. (See the Failure Recovery Guide for further details). However, if you wish to disable recovery as well as remove any resources it maintains, then you can pass true to method TxControl.disable; the default is to use false.
