Hi

I had problems using Jackrabbit in more than one schema on the same
oracle instance.

Jackrabbit assumes that the table name (f.e.: prefix + fs_entry) is
unique across all schemas  used on one oracle instance. So two
Jackrabbit instances using two schemas on the same Oracle instance won't
work.

A solution for the problem is to overwrite the checkSchema methods in
OracleFileSystem and OraclePersistenceManager and consider the schema name.

Here are the first few lines from OraclePersistenceManager.checkSchema():

 protected void checkSchema() throws Exception {
        DatabaseMetaData metaData = con.getMetaData();
        String tableName = schemaObjectPrefix + "NODE";
        *String userName = metaData.getUserName();

        if (metaData.storesLowerCaseIdentifiers()) {
            tableName = tableName.toLowerCase();
        } else if (metaData.storesUpperCaseIdentifiers()) {
            tableName = tableName.toUpperCase();
        }
        *ResultSet rs = metaData.getTables(null, userName, tableName, null);
       ....
}

 * mark the changes - the remainder of the method is from
DBPersistenceManager


best regards
