Function
The XA resource service definition defines the execution environment for managing transactions using the XA resource service.
Explanation
set format
xar_eventtrace_level=ERR|INF|ALL~<<ERR>>
Specify the output level of the XAR event trace information.
Hitachi recommends that you specify ERR in the production environment. If you specify a value other than ERR, the number of inputs and outputs increases, slowing down the processing.
xar_eventtrace_record=maximum-number-of-records-output-to-the-XAR-event-trace-information-file~<unsigned integer>((1-65535))<<8192>>
Specify the maximum number of records output to the XAR event trace information file.
xar_session_time=monitoring-time-for-idle-transaction-branches~<unsigned integer>((10-65535))<<180>> (unit: seconds)
Specify the length of time to monitor an idle transaction branch between End() and Prepare(). When the specified length of time expires, a message is output to roll back the transaction branch. The interval of monitoring the idle status is 10 seconds. Therefore, it may take a while before the idle status is detected.
xar_msdtc_use=Y|N ~<<N>>
Specify whether to use MSDTC linkage.
xar_prf_trace_level=acquisition-level-of-the-XAR-performance-verification-trace ~((((00000000-00000003)) <<00000003>>
Specify the acquisition level of the XAR performance verification trace. To specify multiple acquisition levels, specify the logical sum of the values for those acquisition levels.
For details about the XAR performance verification trace, see the description of troubleshooting in the manual OpenTP1 Description.
You can use the prfget command to export the acquired trace to a file or use the prfed command to edit and output the acquired trace. For details about the prfget and prfed commands, see the manual OpenTP1 Operation.
This operand requires the installation of TP1/Extension 1. If this operand is specified when TP1/Extension 1 has not been installed, operation cannot be guaranteed.
