If the user load is really low and this percentage is set to 2% (the default value), then it is very likely that the time duration between transactions getting monitored will be large. The Request Collection Sampling Rate (%) setting determines how many requests have to be sampled. Missing data in Datasources and JMS Summary workspaces may depend on insufficient Monitoring Level (L2 is required).ДЄlso note that for Request Data to be displayed in workspaces enough user transactions have to be monitored and collected by the Request Aggregator in the Data collector.

JMS Summary: Tracks the time spent on various JMS operations вЂ“ Browse, Send, Receive for both Queues and Topics. Datasources: Tracks operations done on every configured Data source. It is available both at Level 1 and at Level 2 monitoring. Request Analysis: Tracks elapsed time for request completion and breaks down the elapsed time into various J2EE tasks (JDBC, JMS, JNDI). Application Health: Tracks the health of applications and requests based on threshold values obtained from baselining user requests. Request data are displayed in the following TEP workspaces: Request Data Monitoring Level and Sampling Rate can be set during TEMA configuration. Request Aggregator is one of the clients which aggregates the request data from these BCI-generated events and stores them for retrieval by TEMA.

Whenever the instrumented code is executed, ITCAM callbacks are invoked which feed the monitoring data regarding the user transaction to its clients. Request data workspaces get their data from the Byte Code Injection (BCI) done by ITCAM Data Collector into the application and WebSphere system classes. ^ 'Fabsco Shell & Tube - Fabsco Fin-Air'.^ 'Energy Exchanger Company - Tulsa, OK'.'Shell and tube heat exchangers, Heat exchanger manufacturer, Brask Inc - IEE, LA, South, Southern'.

The current member companies of TEMA (in alphabetical order) are: Companies may fabricate other equipment in addition to heat exchangers. The member companies of TEMA must demonstrate high quality exchanger fabrication standards, and possess in-house engineering capability for mechanical and thermal design of shell and tube type heat exchangers. Many different letter combinations are possible. A kettle type reboiler with a removable U-tube bundle is a 'BKU' type. For example, a fixed tubesheet exchanger with bolted removable bonnets is designated as a 'BEM' type.

A letter designation is used for the front head type, shell type, and rear head type of an exchanger. TEMA Exchanger Nomenclature Д«ecause heat exchangers can be configured many different ways, TEMA has standardized the nomenclature of exchanger types. In general, Class C is the least restrictive class, and Class R is the most stringent, insuring more robust designs for longer life in harsher service conditions.

Class C - for general commercial service.

Class R - for refinery and petroleum service.

Each class has different mechanical construction requirements, based on the expected service. TEMA's standard recognizes three separate classifications of exchangers.

Installation, Operation, and Maintenance.

General Fabrication and Performance Information.

The standard is composed of ten sections: Worldwide, the TEMA Standard is used as the construction standard for most shell and tube heat exchangers. The current edition of the TEMA Standard is the Tenth Edition, published in 2019.
