public class DbDemo

extends Object

DbDemo is a simple application using the Z39.50 Client API. Once the application is started, enter a '?' to get help on commands available. Invoke DbDemo with the following flags:

[-d(database.ini)]

Specifies the file that contains the list of databases or contains the configuration information for a particular database. Defaults to databases.ini as used by ZBase.

[-b[sleep_time]]

Signals that DbDemo is running as a background process and all input should be echoed to the output. sleep_time is an optional amount of time to sleep between transactions during batch mode. This is useful for simulating user behavior.

[-o(filename)]

All records displayed will also be output as BER to (filename).

[-i(filename)]

Override stdin. Automatically includes -b option.

[-l]

Turn on logging.

[-s(filename)]

Override stdout and stderr.

[-v]

Same as -l.

The .ini file can be of two formats: 1) It can look like a ZBase databases.ini file. It will have one section named [ZBaseDBs] and that section will have entries named DB1 through DBn. The values of those entries will be the names of the .ini files for the individual databases. 2) It can be a database .ini file. It will have a section named [Database] which will contain the following entries: ZBaseDbType=ORG.oclc.db.DbNewton (optional) class=ORG.oclc.pears.pears (optional, defaults to ORG.oclc.Newton.db.light.light) dbname= This entry is required for pears: pdbfile= Seriously cribbed from ORG.oclc.z39.client.zclient.java
