Configuration and Administration of Tuxedo<br />
° ° Wa<strong>it</strong> time: The time taken by a message in the transportation stage.<br />
° ° CPU time: The CPU time consumed by the service for processing<br />
the request. It only applies to single-threaded servers.<br />
° ° Message size: The Oracle Tuxedo message size.<br />
° ° Execution status: The tpreturn service-return code. It is defined<br />
by the Oracle Tuxedo ATMI interface.<br />
° ° Elapse time: The time elapsed for a call is mon<strong>it</strong>ored.<br />
° ° Pending message number: The number of pending messages to<br />
the network.<br />
° ° Message throughput: The total number of messages and volume<br />
accumulated in the system server mon<strong>it</strong>oring intervals.<br />
° ° Wa<strong>it</strong>ing reply message number: The number of requests in<br />
GWTDOMAIN awa<strong>it</strong>ing a reply from the remote domain.<br />
° ° J2EE-based solution: This is a pure web-based solution w<strong>it</strong>h WEB 2.0<br />
technologies; easy to deploy, configure, and use. The TSAM Console<br />
can be used from anywhere using any standard web browser.<br />
° ° Easy-to-understand metrics database schema. The metrics can be<br />
used for data mining or further business analysis.<br />
• TSAM helps analyze global distributed transactions and correlate transactions<br />
across multiple domains in the tree style. TSAM supports the transaction<br />
mon<strong>it</strong>oring propagation; that is, if mon<strong>it</strong>oring is enabled for the transaction<br />
in<strong>it</strong>iator, the whole transaction path will be mon<strong>it</strong>ored.<br />
• A powerful mon<strong>it</strong>oring policy can help achieve the exact mon<strong>it</strong>oring results<br />
while reducing the impact on performance. The sampling can be based on<br />
interval, ratio, and runtime data. The mon<strong>it</strong>oring can be turned on or off<br />
dynamically w<strong>it</strong>hout restarting the application.<br />
• Comprehensive SLA alert configurations based on mon<strong>it</strong>oring metrics.<br />
Alert evaluation is based on Tuxedo FML Boolean expressions. The event<br />
generated by alert can be posted to the Tuxedo Event Broker. Some alert<br />
types can also drop stale service requests.<br />
• Programming APIs that retrieve the metadata packaged in a mon<strong>it</strong>ored<br />
call help developers make application decisions dynamically.<br />
