Field Detail

storeIsMemory

public boolean storeIsMemory

Sets whether tables are to be located in-memory or on disk. Creating in-memory tables should append "STORE MEMORY" to the "CREATE TABLE" statement. Creating disk-based tables should append "STORE DISK". Since cursor hold over commit can not apply to M-tables (which will cause SOLID Table Error 13187: The cursor cannot continue accessing M-tables after the transaction has committed or aborted. The statement must be re-executed.), the default is STORE DISK. The default concurrency control mechanism depends on the table type: Disk-based tables (D-tables) are by default optimistic. Main-memory tables (M-tables) are always pessimistic. Since OpenJPA applications expects lock waits (as usually is done with normal pessimistic databases), the server should be set to the pessimistic mode. The optimistic mode is about not waiting for the locks at all. That increases concurrency but requires more programming. The pessimistic mode with the READ COMMITTED isolation level (default) should get as much concurrency as one might need. The pessimistic locking mode can be set in solid.ini: [General] Pessimistic=yes

useTriggersForAutoAssign

public boolean useTriggersForAutoAssign

If true, then simulate auto-assigned values in SolidDB by using a trigger that inserts a sequence value into the primary key value when a row is inserted.

autoAssignSequenceName

public java.lang.String autoAssignSequenceName

The global sequence name to use for auto-assign simulation.

openjpa3GeneratedKeyNames

public boolean openjpa3GeneratedKeyNames

Flag to use OpenJPA 0.3 style naming for auto assign sequence name and trigger name for backwards compatibility.

lockingMode

public java.lang.String lockingMode

Possible values for LockingMode are "PESSIMISTIC" and "OPTIMISTIC"
