clustering configuration question
Hi,
I'm a little confused about the clustering configuration. The wiki page
(http://wiki.apache.org/jackrabbit/Clustering) first says all cluster
nodes need their own private FileSystem and Search index. But the
requirements section does not mention the FileSystem configuration.
I currently have (as it seems) a working cluster setup with two nodes
(different machines), but I'm very suspicious about the configuration.
Here it is:
<Cluster id="node1">
<Journal
class="org.apache.jackrabbit.core.journal.OracleDatabaseJournal">
<param name="revision" value="${rep.home}/revision.log" />
<param name="driver" value="oracle.jdbc.driver.OracleDriver" />
<param name="url" value="<db_url>" />
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
</Journal>
</Cluster>
<FileSystem class="org.apache.jackrabbit.core.fs.db.OracleFileSystem">
<param name="url" value="<db_url>"/>
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
<param name="schemaObjectPrefix" value="rep_"/>
</FileSystem>
<Security ... />
<Workspace name="${wsp.name}">
<FileSystem
class="org.apache.jackrabbit.core.fs.db.OracleFileSystem">
<param name="url" value="<db_url>"/>
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
<param name="schemaObjectPrefix" value="wrk_"/>
</FileSystem>
<PersistenceManager
class="org.apache.jackrabbit.core.persistence.db.OraclePersistenceManager">
<param name="url" value="<db_url>"/>
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
<param name="schemaObjectPrefix" value="${wsp.name}_"/>
<param name="externalBLOBs" value="false"/>
</PersistenceManager>
<SearchIndex ... />
</Workspace>
<Versioning rootPath="${rep.home}/version">
<FileSystem
class="org.apache.jackrabbit.core.fs.db.OracleFileSystem">
<param name="url" value="<db_url>"/>
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
<param name="schemaObjectPrefix" value="ver_"/>
</FileSystem>
<PersistenceManager
class="org.apache.jackrabbit.core.persistence.db.OraclePersistenceManager">
<param name="url" value="<db_url>"/>
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
<param name="schemaObjectPrefix" value="version_"/>
<param name="externalBLOBs" value="false"/>
</PersistenceManager>
</Versioning>
<SearchIndex ... />
<DataStore ... />
For the second cluster node, the repository.xml file is almost the same,
except the global <Cluster> and <FileSystem> configurations:
<Cluster id="node2">
<Journal
class="org.apache.jackrabbit.core.journal.OracleDatabaseJournal">
<param name="revision" value="${rep.home}/revision.log" />
<param name="driver" value="oracle.jdbc.driver.OracleDriver" />
<param name="url" value="<db_url>" />
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
</Journal>
</Cluster>
<FileSystem class="org.apache.jackrabbit.core.fs.db.OracleFileSystem">
<param name="url" value="<db_url>"/>
<param name="user" value="<db_user>"/>
<param name="password" value="<db_passwd>"/>
<param name="schemaObjectPrefix" value="rep_node2_"/>
</FileSystem>
So basically, the cluster id's are different (duh) and only the global
filesystem is different. The tables used for the workspace filesystem
and versioning are the same. I imagine all filesystems should be either
different or all the same for all cluster nodes. Could anybody shed some
light on this?
TIA

Use a LocalFileSystem for all the FileSystem occurrences. It is not
used by the persistence manager you have chosen (AFAICS), hence no
data will be stored there. See also here:
