If i prove with the JNDI parameters:

<param name="driver" value="javax.naming.InitialContext"/>
<param name="url" value="java:comp/env/jdbc/LiferayPool"/>

mark this error:
"jdbc not bound"

In contrast if only it's change in FileSystem by jdbc whether it works correctly

repository.xml (example):

<Repository>
<!-- FILESYSTEM -->
<FileSystem class="org.apache.jackrabbit.core.fs.db.OracleFileSystem">
<param name="driver" value="oracle.jdbc.driver.OracleDriver"/>
<param name="url" value="jdbc:oracle:thin:@xxx.xxx.xxx.xxx:1521:name" />
<param name="user" value="qua" />
<param name="password" value="qua" />
<param name="schema" value="oracle"/>
<param name="schemaObjectPrefix" value="LR_FS_"/>
</FileSystem>
