What LockManager does?

In general, LockManager stores Lock objects, so it can give a Lock object or can release it.

Also, LockManager is responsible for removing Locks that live too long. This parameter may be configured with "time-out" property.

JCR provides two basic implementations of LockManager:

In this article, we will mostly mention about CacheableLockManagerImpl.

You can enable LockManager by adding lock-manager-configuration to workspace-configuration.

For example:

<workspace name="ws">

   ...

   <lock-manager class="org.exoplatform.services.jcr.impl.core.lock.jbosscache.CacheableLockManagerImpl">

      <properties>

         <property name="time-out" value="15m" />

         ...

      </properties>

   </lock-manager>               

   ...

</workspace>
