ActiveSpaces Properties

The ActiveSpaces JDBC Driver makes invocations of the ActiveSpaces Java API. The ActiveSpaces Java API provides several API methods where properties can be specified which are needed to connect to the data grid or which affect the behavior of the data grid. However, in the JDBC driver you can only specify properties when you first connect to the data grid. Therefore, any properties that must be applied to Statements should also be specified in the set of properties used to connect to the data grid. When the JDBC API offers a method to set a value that can also be set using a property, the JDBC API's setting takes precedence.

The following partial list describes the most frequently used connection properties that can be specified. See the tables that follow to see other Connection, Session, and Statement properties that can be included in the set of properties specified when connecting to the data grid.
Property Description Default Value
com.tibco.tibdg.gridnameName of the data grid _default
com.tibco.tibdg.realmurlRealm Service URL. The Realm Service URLs use the pipe character (|) as a separator to provide a list of URLs. http://localhost:8080
com.tibco.tibdg.connectwaittimeThe amount of time to wait for a connection to be established. 0.1 seconds
com.tibco.tibdg.timeoutThe amount of time to wait for responses from the data grid. 5.0 seconds
When specifying properties as part of the JDBC URL, the full property name or the property name without the com.tibco.tibdg prefix can be used. For example: 
jdbc:tibco:tibdg:_default;com.tibco.tibdg.realmurl=http://localhost:8080
Connection Property Description Default Value
com.tibco.tibdg.clientlabelSet the name used to refer to the client in monitoring and management components.A string containing the grid name, client instance ID, and ActiveSpaces version.
com.tibco.tibdg.connectbindstrategy

Specifies how a client must establish a proxy connection.

0=choose a proxy at random

1=choose a proxy from the proxies listed in the com.tibco.tibdg.connectproxynames property

2=choose the proxy with the lowest load from the proxy responses received. This is the balanced bind strategy.

0
com.tibco.tibdg.connectnumresponsesSpecifies the number of responses to receive from proxies before the client stops looking for proxy responses. Only used when com.tibco.tibdg.connectbindstrategy has been set to 0 (random) or 2 (balanced) 2147483647
com.tibco.tibdg.connectproxynamesA pipe '|' delimited list of proxy names for com.tibco.tibdg.connectbindstrategyNone
com.tibco.tibdg.realmconnectretriesSpecifies the number of times the underlying TIBCO FTL client library attempts to connect to the Realm.5
com.tibco.tibdg.tporttype

Specifies the type of TIBCO FTL transport that the client uses to connect to proxies.

0=DTCP

1=AUTO

Connection type is determined by the grid configuration.
com.tibco.tibdg.trust.fileSpecifies the given file must be used to verify the realm server's certificate when com.tibco.tibdg.trust.type is set to trust_fileNone
com.tibco.tibdg.trust.type

Specifies the type of "trust" to use when connecting to the realm server.

trust_file=Use the trust file specified in the com.tibco.tibdg.trust.file property to verify the realm server's certificate.

trust_everyone=The application trusts any realm server without verifying the trust in the realm server's certificate. Use for development only.

None
com.tibco.tibdg.usernameSpecifies the username to use when connecting to a secure realm server.None
com.tibco.tibdg.userpasswordSpecifies the password to use when connecting to a secure realm server.None
Session Property Description Default
com.tibco.tibdg.checkpointname Use the specified checkpoint as the data source for this session's read operations. None
com.tibco.tibdg.immutablerows

Specifies whether rows returned in ResultSets are immutable.

true=rows cannot be modified

false=rows can be modified

 false
Statement Property Description Default
com.tibco.tibdg.statement.consistency

When running queries, determines whether to wait for any previous transactions to be committed.

Possible string values: global_snapshot, snapshot

 global_snapshot - waits for writes to be committed
com.tibco.tibdg.statement.prefetch

Indicates the number of result rows to return to the client at a time for a query being run. Calling Statement.setFetchSize() overrides this property setting for the statement.

 256
com.tibco.tibdg.statement.fetch.timeout Specifies how long (in seconds) the application waits for the next batch of query result rows before timing out. Calling Statement.setQueryTimeout() overrides this property and the com.tibco.tibdg.statement.update.timeout property for the statement. If this property is not provided, the current timeout for the parent Connection is used.
com.tibco.tibdg.statement.update.timeout Specifies how long (in seconds) the application waits for a reply to an ExecuteUpdate request, on a statement, before timing out. Calling Statement.setQueryTimeout() overrides this property and the com.tibco.tibdg.statement.fetch.timeout property for the statement. If this property is not supplied the current timeout for the parent Connection is used.
