transaction_optional

The transaction_optional attribute specifies whether to execute a service as part of a global transaction, depending on whether the called environment is located inside or outside the transaction.

• If the interface or operation with this attribute specified is called inside a global transaction, the service is executed as part of the transaction. If it is called outside the transaction, the service is executed as a non-transaction RPC.
• This attribute cannot be specified at the same time as the transaction_mandatory attribute.
