5427.0. "Historian MIR files and APTUSER" by TAV02::KALAI () Wed Aug 04 1993 06:44

	We want to try to get reports from Historian MIR files with
the APTUSER.
	-If someone out there work on that I will be very happy to get
	 some input.

	- In order to try I need to know:
	 record structure,field,datatype and size of the historian mir files.



Thanks
Yael Kalai

	The record structure in the historical MIR is a private agreement between the Historian and Information Manager. Although I don't think that in the future it can be changed this is a possibility. This record contains p_out, time stamp and status returned from the corresponding Show directive. By this means that the size of the record is depend of the p_out for corresponding entity class and partition. If you want to write a generic procedure you should scan p_out and determine a data type and name for every returned attribute. This can be done using data dictionary. In other words you have to repeat the same procedure what the Exporter does. In addition to this you have to know the correspondence between the domain name and the name of the historical MIR. Again this is built using private a agreement. To retrieve the historical data I would recommend to use the Past Time Show command which returns all data you need and saves you time to learn MCC internals. Sam
