public native void put(DbLockTab locktab)
    throws DbException;

Description

The DbLock.put method releases a lock, previously obtained from the specified DbLockTab using DbLockTab.get.

If a process dies while holding locks, those locks remain held and are never released. In this case, all processes should exit as quickly as possible, so that database recovery can be run.

Errors

The DbLock.put method may fail and throw an exception for any of the errors specified for the following Berkeley DB and C library functions: abort(3), fcntl(3), fflush(3), fprintf(3), fsync(3), getpid(3), DbLockTab.detect, lseek(3), memcpy(3), memset(3), mmap(3), munmap(3), shmat(3), shmdt(3), strerror(3), vfprintf(3), vsnprintf(3), and write(3).

In addition, the DbLock.put method may fail and throw an exception encapsulating errno for the following conditions:

EACCES

An attempt was made to release lock held by another locker.

EINVAL

An invalid flag value or parameter was specified.
