Function
Starts replication of a database in master mode. Before you specify this
attribute, you must cleanly shut down the database on the master system, perform a
file system copy of the database to the slave system, and specify the
startSlave=true
attribute. For details, see the topic "Starting and running replication" under
"Replicating databases" in the Derby Server and Administration Guide.
If the master database is already booted and any unlogged operations are
running when the user specifies startMaster=true, the attempt to start
the master fails and an error message appears.
For more information on replication, see the other topics under
"Replicating databases" in the Derby Server and Administration Guide.
Combining with other attributes
You must specify a database name in the connection URL, either in the
subprotocol or by using the databaseName=nameofDatabase
attribute.
You must specify this attribute in conjunction with the slaveHost=hostname
attribute. You may also specify this attribute in conjunction with the slavePort=portValue
attribute. If you do not specify the slavePort=portValue attribute, the
default port value is 4851.
If authentication or authorization is turned on, you
must also specify this attribute in conjunction with the user=userName and
password=userPassword
attributes. If authorization is turned on, the user must be the database owner.
You may not specify this attribute in conjunction with any attributes not
mentioned in this section.
Examples
-- start master using database name in subprotocol, default slave
-- port, authorization
jdbc:derby:myDB;startMaster=true;slaveHost=elsewhere;user=mary;
password=little88lamb
-- start master using databaseName attribute, non-default slave
-- port, no security
jdbc:derby:;databaseName=myDB;startMaster=true;slaveHost=elsewhere;
slavePort=4852
