Documentation of the MyTransaction tool used for example.test.

INTRODUCTION

The MyTransaction tool is used to test the longterm-transaction-feature of tclmqmsgque.

To test this feature the client connect to the server and send two service-calls:

  • one longterm-transaction-service-call using the low-api
  • one longterm-transaction-service-call using the high-api

The service-call itself is quite simple:

  • the private part is a string : Privat_Data_1 or Privat_Data_2
  • the public part is an integer : 1111 or 2222

The GOAL for this test is:

  • test the longterm-transaction-feature
  • test the BufferListCheckOptionC with and without default-value
  • test the callback-feature with and without error
