standard edition + drbd + pacemaker

kamilpFeb 10 2011
hello,

i want to ask if anyone has experience with installing oracle db standart editon on linux cluster with pacemaker and drbd. for testing we have installed suse cluster with shared /opt/database and /opt/oraInstall over drbd. drbd filesystem is mounted on one node, slave is synced. shared ip and db startup is served by pacemaker. private drbd interchange network is bonded 4x1gbit.
working well, however not supported by oracle ;-/

my question is anyone using this or similar in production ? do i need to db license for both servers (technically, only one is possible to start) ?

It doesn't itself, but since you can feed jaxb a DOM document from any source, you can always use a processor that does support xinclude and feed the result to the unmarshaller. Try this:

(1) Get the XInclude Engine at http://xincluder.sourceforge.net/

(2) build the xinclude document with something like:


DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware( true );
factory.setCoalescing( true );
DocumentBuilder parser = factory.newDocumentBuilder();
InputSource input = new InputSource();
input.setByteStream( new FileInputStream( fname ) );
Document masterDoc = parser.parse( input );
Document doc = DOMXIncluder.merge( masterDoc, input.getSystemId() );

(3) then unmarshal the document with:

JAXBContext jc = JAXBContext.newInstance( "my.context" );
Unmarshaller u = jc.createUnmarshaller();
MyClass x = (MyClass) u.unmarshal( doc );

there's probably a faster Sax equivalent of this. Also works (better) with Castor.

hope this helps,

Oops! sorry: looking at it again, I see I misread your question. I thought you meant using xinclude in a datafile (which I'd just worked out how to do) rather than in a schema (which I haven't worked out). Apologies.

Yes. JAXB 1.0 supports included and imported schemas.
Can you please attach the COS.xsd too
