Table 24.1
openjms.datasource
openjms.sql_file
Partition level porperties for OpenJMS (continued)
Property Name Description Default Value
openjms.datasource_lookup_interval
openjms.max_datasource_lookup_retries
openjms.recreate_database_on_startup
This property specifies the JNDI
name of the datasource that is used
to persist messages in OpenJMS. If
this datasource is the same as the
one that your application uses, then
the JDBC connection pool will be
shared among them and a single
JDBC connection will be used both
to persist messages and provide
data access to your application,
thereby avoiding a need for 2PC. If
the specified datasource is not
available in the JNDI namespace at
the startup time, the startup code
will use the properties
openjms.datasource_lookup_interval,
and
openjms.max_datasource_lookup_retrie
s described below, to make multiple
attempts to access the target
datasource. Despite that, if the
lookup fails, the initialization code
will internally construct a datasource
from the information specified in the
configuration (openjms.xml) file.
Note
The startup code will use the
information from openjms.xml file
only if the user specified
datasource is not available. If
the datasource is pre-deployed
or available in JNDI, RDBMS
configuration in the openjms.xml
file will be ignored.
This property is used to specify the
file that contains the SQL
statements to drop, and create
database tables. These tables are
used by OpenJMS for message
persistence.
This property specifies the duration
between successive datasource
lookup attempts. See the property
openjms.datasource property above.
This property specifies the number
of attempts to lookup for the
datasource before attempting to use
the default datasource.See the
property openjms.datasource property
above.
This property when set will cause
re-creation of database across each
startup of the service. This is useful
for cases where previous messages
are not needed in the subsequent
runs (for example, while testing).
