Chapter 2: Setting Up A New Installation
2.2.2.2.2
Nanometrics event catalogs
Nanometrics event catalogs list events that have been detected automatically by the
Nanometrics data servers. You can create, modify, and remove Nanometrics event catalogs. You can update the list of events, and clear the list.
Caution All trace data and triggers are reloaded from the ringbuffers when an
event is opened. Therefore, once the trace data expires from the ringbuffers, events will load blank traces. To preserve trace data for interesting events, save the events to an Earthworm database.
2.2.2.2.3
Trigger catalogs
Trigger catalogs list picks that have been detected automatically by the Nanometrics
data servers. Events are generated when enough channels trigger within a short enough
time period (see also NaqsServer documentation). Individual channels may experience
spikes and generate triggers.
You can create, modify, and remove trigger catalogs. You can update the list of triggers
in a catalog, and clear the list.
2.2.2.3
SEED file catalogs
SEED file catalogs can be defined to contain events for a given time period, or to contain all events if a time period is not specified. Events are exported from SEED files, or
saved from Earthworm databases or Nanometrics data servers. (See Section 2.2.1.3.1
on page 10 for information on SEED file limitations.)
2.3 Set up a new installation of Atlas
When you start Atlas for the first time, the Catalogs tabbed panel will contain an empty
folder called Data Sources. Before data can be loaded in Atlas, you must create a structure of data source(s) and catalogs. Procedures for defining data source connections and
catalogs are the same for both the initial setup, described below, and for subsequent
additions to the data source and catalog structure, described in Chapter 4.
Setting up a new installation requires three general steps:
1. Connect to an Earthworm compatible database (Section 2.3.1 on page 13) or a
SEED file (Section 2.3.2 on page 13).
2. Connect to a Nanometrics data server (Section 2.3.3 on page 14).
3. Create catalogs to organise and view data (Section 2.3.4 on page 14).
Note For Atlas using Oracle connections, before you can access a particular
database you need to use an Oracle assistant to list the database in your
Oracle settings. See the sections on adding databases to the client in the
“Atlas Installation and Maintenance Guide”.
