setOnline

void setOnline()

lockRecord

boolean lockRecord(com.orientechnologies.orient.core.db.record.OIdentifiable iRecord,
                   ODistributedRequestId iRequestId,
                   long timeout)

Locks the record to be sure distributed transactions never work concurrently against the same records in the meanwhile the transaction is executed and the OCompleteTxTask is not arrived.

Parameters:

iRecord - Record to lock

iRequestId - Request id

timeout - Timeout in ms to wait for the lock

Throws:

ODistributedRecordLockedException - if the record wasn't locked

Unlocks the record previously locked through #lockRecord method.

Parameters:

iRecord -

requestId -
