Field Detail

lockModeEnabled

public boolean lockModeEnabled
If true, then we will issue a "SET LOCK MODE TO WAIT N" statement whenever we create a Connection, in order allow waiting on locks.


lockWaitSeconds

public int lockWaitSeconds
If lockModeEnabled is true, then this parameter specifies the number of seconds we will wait to obtain a lock for inserts and pessimistic locking.


swapSchemaAndCatalog

public boolean swapSchemaAndCatalog
Informix JDBC metadata for all known drivers returns with the table catalog and the table schema name swapped. A true value for this property indicates that they should be reversed.
