RSView Supervisory Edition Installation Guide

13 • USING DATA LOGGING• • • • •Specifying the storage formatIn the Setup tab of the Data Log Models editor you provide a log file identifier string,which becomes part of the file name for the data log files, and select a storage format. Youcan also type a description of the model. This is for information only.When you select File Set as the storage format and you plan to log string tags, specify thenumber of characters to be logged.When you select ODBC database as the storage format, type the path and file name of theODBC data source, and specify the ODBC tables that will be used, or create new tables.To create tables for a new data source, click Create Tables. If RSView cannot create thetables automatically, you will have to open the database using its editing tool, and createthe tables manually.To select an existing table from the specified database, click the Browse button and thenselect a table in the Select ODBC Table dialog box. To view the order, type, length, andprecision of the fields in the table, click the table to select it and then click Details.For more information see, “Working with ODBC data sources” on page 13-7.13 • PlaceholderSetting up log pathsSet up logging paths in the Paths tab of the Data Log Models editor.If the storage format is file sets, specify the primary path, and an optional secondary filepath in case the primary path becomes unavailable.If the storage format is ODBC, you can specify a backup file path for the ODBC database.To prevent loss of data, you can set up a secondary or backup logging path. If the diskspace for the primary path is full, data logging switches to the secondary path, if set up,until space becomes available on the primary path.If you do not do this, when the primary path runs out of disk space, data logging stops andno more log files are created.For details see Help.Setting up and managing data log filesIn the File Management tab of the Data Log Models editor, you specify when to start newfiles and when to delete old files. If the data log model uses the ODBC format, data isadded continually to the same database, and this section does not apply. If the data logmodel uses file sets, RSView logs the data to sets of files.13-5
