Scenario specific message staging and logging in PI 7.31 AAE

[nageshwar_reddy]

PI 7.31 introduced a new concept called scenario specific message staging and logging. You can now enable or disable message staging and logging for the specific integration scenario. Scenario specific persistence (staging or logging) is available only for scenarios involving advanced adapter engine. In other words, scenario specific persistence is applicable only to integrated configurations.

As you can see from the below screenshots, there is a new tab "Advanced Settings" in Integrated configuration.

Staging

With this option, you can save message versions, edit them and restart the processing of the changed message. The following values are available as drop down for each step and they are self explanatory. 

• None - Message version is not saved
• Store on error - Message version is saved only if the following step has error
• Save - Message version is always saved

Logging

With this option, you can save message versions for logging purposes. Note that with this option you only have read only access to the message version. The following values are available as drop down for each step and they are self explanatory

• None - Message version is not saved
• Log - Message version saved for logging
• Log on error -Message version saved for logging in case of error
• Log without payload - Message version saved for logging without payload
• Log on error without payload - Message version is saved for logging only on error without payload
