name for all data in your statistics data set.

iii. Save the Export Definition Description.

Select:

File

Save...

In the

Selection

field, type a file name such as

exp_def_desc_1

(SDE automatically appends the .sde

suffix to the file name ), and then press ENTER or RETURN.

In exp_def_desc_1.sde, SDE saves the description of what data to export.

g. Allow SPECTRUM some time to collect data.

If polling and logging have not been enabled until now, SPECTRUM will need about two days to collect a meaningful

amount of data. We recommend that you collect two days’ worth of data so that you will have a better sense of what

typical data are like, what a typical PDB is like, and what typical reports are like as you explore your PDB in later tasks.

h. Start the export process.

After two days, select the following from the current window:

File -> Export Now -> OK

SDE starts the export process, which uses:

the exp_def_desc_1.sde description for what data to export

the Export Range value of Day for how much data to export

the directory SPECTRUM_home/export.output (by default) for the directory to which SDE will write the

data.

In summary, SDE exports all model data to the model data set in the SPECTRUM_home/export.output directory

and exports the previous day’s statistics data (logged data) for the selected models to the statistics

data set in

SPECTRUM_home

/export.output.

The model data set contains model-handle to model-name mappings for the selected model type’s models that

were present on the previous day. Each observation in the model data set contains the mapping of one model

handle (in hex) to its model name (host name).

In a later task you will define a libref named specgway that points to the

SPECTRUM_home

/export.output directory. At that point you will refer to the model data set as

specgway.model.

The statistics data set contains the metrics logged during the previous day on the selected model type’s

models. Each observation in the statistics data set contains a timestamp, a model handle (in hex), and the value at

that time of each attribute that was logged for that model handle.

Note: To be exact, the data set that contains the statistics has a name of stat not statistics. In a later task
