Effective transaction level The effective transaction level is a range between the highest maximum transaction level of all collaboration objects and the lowest maximum transaction level of all connectors that are bound to the object. You can lower the effective transaction level of a collaboration if you need to bind to a connector that does not support a certain transaction level. To change the effective transaction level, choose the desired value from the Effective transaction level drop-down list and then click OK. Note: You cannot bind objects whose transaction levels are incompatible. If you need to bind such objects to a collaboration, you must adjust the supported transaction levels accordingly. Minimum transaction level The minimum transaction level specifies the lowest transaction level of the collaboration template and any collaboration objects based on it. For instance, if the developer of the collaboration template specified a minimum transaction level of Best Effort for the template, then all objects based on the template must operate at Best Effort or Stringent. As described in the section on "Effective transaction level," all components bound to the collaboration object must support its effective transaction level. The minimum transaction level is, then, a way for the collaboration template developer to dictate the lowest transaction level at which the entire interface in which collaboration objects based on the template will execute. The Minimum transaction level field is read-only when configuring a collaboration object; it can only be changed in the collaboration template. For more information about making changes to collaboration templates, see the Collaboration Development Guide. System trace level You can configure collaboration objects so that information about the execution of the collaboration is reported in the server output. To do so, select the desired value in the System trace level drop-down menu. Table 16 describes the different levels and the types of information reported at each: Table 16. System trace levels System trace level 0 - No Tracing 1 - Collaboration operations 2 - And collaboration events 3 - And state transactions 4 - And incoming/outgoing messages Reported information No information is traced at this level Traces the receipt of business objects from connectors and the starting of scenarios Prints messages for level 1, as well as the start and completion of each scenario, including both forward execution and rollback Prints messages for levels 1 and 2, as well as the execution of each scenario decision block or action node Prints messages for levels 1 through 3, as well as the sending and receipt of each business object by each scenario Chapter 9.
