Tandem Performance Load Data (TPLD)
Tandem Performance Load Data (TPLD)
The TPLD component loads the consolidated data file and creates component TPDC
entity data files, from which you can generate optional reports using Enform and other
programs.
System Performance Analysis Using Measure (SPAM)
The SPAM component loads the consolidated performance data (UWS) file and
creates both Measure and aggregate entity files used to generate reports. After all of
these entities are created, the HP Enform product can use the compiled queries to
generate performance charts and reports.To invoke SPAM use the TGATHER TACL
macro. The compiled queries are invoked by the TPRODUCE TACL macro.
Tandem Performance Deferred Processing (TPDP)
The TPDP component can be run at any time to generate consolidated performance
data (UWS) files based on data you have collected and retained on disk using TPDC.
Using deferred processing (by running TPDC with the DEFER option and later using
TPDP) lets you perform the processor-intensive UWS file creation at a time when your
system resources are less in demand. The DEFER option notifies TPDC to retain its
data, but you must notify TPDP to retain the data as well, or the data (DWS file and
raw Measure data) is not kept after TPDP runs.
Data Files (RWS, DWS, UWS)
Three data file formats are used during TPDC processing:
•
RWS file — Created by TPDC at the start of data collection. This file stores all
collected data while TPDC runs. At the end of data collection, TPDC uses this file’s
data to create the DWS file. Once the DWS file is created, the RWS file is purged.
If TPDC terminates unexpectedly, or if the CPU TPDC runs on fails during data
collection, the RWS file can be used as the input file into TPDP or to generate
reports on the collected data even though TPDC did not create a DWS file for it.
•
DWS file — Created by TPDC at the end of data collection based on the RWS file
data. This file optimizes the data so it can be fed into the consolidated UWS file
format.
Unless otherwise specified, the DWS file is deleted once it is used to create a
UWS file. Therefore, to keep performance data on your system so you can later
generate more reports from it, when running TPDC, TPDP, or to specify that the
DWS file be retained, use the RETAIN option.
•
UWS file — created by TPDC itself, TPDP, or based on the DWS (or RWS) file.
These consolidated performance data files are used directly to create the
performance reports for your system. For interval processing, a UWS file is created
for each interval.
