Oracle Communications Data Model for Windows - Communications Data Model

Hi,
Is evaluation copy of OCDM available for Windows?
Regards,
Bhavesh 

Dear Bhavesh,
Unfortunately not yet. The fact that OCDM is a telco specific enterprise wide DWH, requires normally a "big" machine.
For an evaluation, I suggest you use VMWare + Linux + ODB 11gR2 with partitioning+mining+OLAP (+OCDM) options.
Beware however that you will need at least a dual core and enough disk space (10GB is the strict minimum) and memory...
The best would be to implement all this on a separate bootable Hard drive.
Hope this helps,
Regards
Axel. 

Folks
Is it possible to get a version of the model to view? 

Yes, this is possible: The front-end via OBIEE (default) as well as the back-end (what happens inside OCDM - as flash demo).
I suggest you contact your CGBU Sales Rep to organize for you the demonstration.
Best regards,
Axel.

Optimal IDM Infrastructure

I'm looking to find out what people out there are using for their IDM infrastructure and what you think is the optimal way to go.
We are currently running IDM 6 SP3 on Windows 2003. SQL Server 2005 for the repository, Weblogic 8.1 for the App Server. Both the app server and DB are running on VMWare.
We are currently having issues with this setup and looking to improve it, any thoughts would be appreciated. 
Hello.
I honestly can't offer much advice on this; but will say that in looking through the Release Notes, it seems that IdM affords you a number of options on the Operating System, the Application Server, and the RDBMS. So at a high-level, it seems that you can probably use the infrastructure (OS, AS and RDBMS) that you have the most experience with.
In other words, since the IdM REPO is an RDBMS, you probably have a 'favorite' RDBMS where you have DBA expertise in-house, have established backup / recovery / high-availability models and procedures in-place. Same idea for the OS and App Server.
I'd suggest two things. First -- consult with someone who can take the time and analyze your environment and your company's preferences, to design an 'optimal' architecture for your needs. This includes not only the infrastructure pieces, but also to address sizing / loading issues, availability and fault-tolerance needs, requirements collection, etc. Second -- unless otherwise inclined, I'd lean towards the components where you have expertise.
VMWare is a really cool utility. I use it all the time and think it's fantastic. But keep in mind that there's another layer of network communication that must occur to go from the virtual network (VNET) to/from the physical network; so if you're configuring VMWare instances, I'd just stay aware of this extra layer.
<SoapBox>
Hopefully others have more experience with deploying IdM and have better advice for you.  The word of caution I'd give you is that while someone else may say that configuration XYZ was 'optimal' for them, it may not be optimal for your environment -- your preferences, your 'favorites', your loads, your user communities, etc.  That's why I think you'd be further ahead by consulting doing the analysis of your environment and needs will find the best match for your deployment.
</SoapBox>Good Luck!

Hardware requirements for WebCenter Sites?

Hi,
I didn't found hardware requirements/recommendations for this product.
Is there any official document somewhere?
Other opinions?
Best Regards,
Martins 
There isn't a generic sizing document as such, you would be best advised to speak with your Oracle sales representative as there are very many factors involved in sizing. To give a rough indication of lowest requirements, a bare-bones single instance of Webcenter Sites (not Gadget, Community, etc) for development/testing could run on a single 32bit or 64bit core with 2gb heap, with a small application server like tomcat, and Oracle Database standard/express.

Manage SPARC LDOMs with the OVM x86 GUI?

Today I watched this recent Oracle video: http://www.youtube.com/watch?v=MuGGZ1uLeN8
Note the use of "Oracle VM Manager" to migrate SPARC guest domains between a T3 and T4 host (see 0:18 to 0:36).
I'm fairly confident this is the Linux-based tool that comes with the OVM for x86 product. I don't think it's OC for OEM.
Does anyone know whether you can use Oracle VM Manager with SPARC? I would be interested to hear more about it.
I have never seen this before, perhaps it is an upcoming feature? Thanks in advance for any info... -cheers, CSB 
You are correct in spotting that it is an Oracle VM Manager instance managing a SPARC machine - it is not a product available to customers yet but I'd hope that we can talk more about it soon.
Currently Oracle Enterprise Manager Ops Center is the management tool for Oracle VM Server for SPARC (LDoms). http://www.oracle.com/us/products/enterprise-manager/opscenter/index.html 
Thank you for the info Liam. I understand how it is with as-yet unreleased products, however Oracle did post it on YouTube for everybody to see. =-)
We reviewed OC 12c, however the presenters (who seemed quite knowledgeable) indicated that it lacked two features which we consider necessary:
1) Ability to manage hosts using split I/O domains (either in a fresh setup, or an imported brown-field)
2) Ability to import a brown-field with shared storage (i.e. we are unable to migrate pre-existing guests)
The first shortcoming is curious, as split I/O has been a feature of LDOMs since v1.0. The increased resiliency is very desirable in the enterprise.
The second issue is odd, in that (IMHO) it should be relatively easy to manually identify backing devices across a cluster of hosts at import time.
I will be quite interested to see if the upcoming product addresses either of these issues. Please feel free to reply when it is permissible.
Again IMHO: Without comprehensive management, OVM for SPARC appears to lack parity with VSphere, POWER HMC, and even VirtualBox.
I love LDOMs, but the stakeholders need to see the do-everything GUI before this wonderful technology will gain share in shops such as those.
Please feel free to correct the record if I have gotten any of the above wrong. Thanks again... -cheers, CSB 
Can anybody address the issues raised above? Are there any other available management solutions that I've missed? Thanks. 
I agree what Craig said as well, we would need a proper GUI to handle LDOM farms.
I noticed that same GUI in the video and something like that would be perfect for the task. Ops Center is way too slow and cumbersome to be trusted in critical operations imo, we use it as asset inventory, alerting and reporting tool only.
For Liam(or any1 from Oracle) can you give at least a rough idea when the GUI could be expected for SPARC? This year or the next?

So the $64,000 question seems to be "when will we be able to get our hands on Oracle VM Manager for LDoms?"... As some of you with keen eyes have seen, we've been showing it in demonstrations. We typically don't demonstrate things that we aren't getting pretty close with (pretty close = 6months or less). I can say that we will be releasing a "technology preview" of the Oracle VM manager in weeks, not months. This will let customers start to get their hands on it to test and evaluate. We will continue to enhance the Oracle VM Manager on SPARC leading up to a full product release with full support after the technology preview period is complete. So the tech preview will have some functional limitations, and may not be as elegant/simple to install as the full product version will be. We'll have more to say, and a pointer to how you can download very very soon.
JF 
John, thanks for the update. I look forward to seeing the preview. =-)
For me, the $64K question is whether the new VM Manager will manage sun4v hosts with multiple I/O domains.
Split I/O has been an LDOMs feature since the beginning, however Ops Center 12c cannot handle such a configuration.
Enterprise customers need to use multiple service domains per host, so IMHO it seems weird that this capability isn't present.
The $32K question: Can I import existing (brown-field) hosts and guests that are configured for live migration?
My understanding is that OC 12c cannot import pre-existing shared storage, and so cannot migrate guests using that.
Again, brown-field importation (even with a wizard or other manual assist) should IMHO be a fundamental enterprise feature.
Any thoughts on those two capabilities? Thx. -cheers, CSB 
Craig, I prefer the easier $2k questions ;-)
Supporting split-bus (multiple IO domain) configurations is vital. We agree that all of our serious datacenter customers use that as a best practice. As you've noted, OpsCenter has thus far not supported those configurations well, but that is being addressed as a top priority. One of the challenges we have with the Oracle VM Manager is its origin as a management entity for Xen deployments on x86, where there is a notion of a single "dom0". We are having to teach OVM Manager about LDoms control infrastructure (control domain, multiple IO domains etc.) - it is one of a dozen really important things that we are working madly on.
Brownfield is also in that dozen really important things - OVM manager has a leg up as it already has some brownfield support now; we expect even in the technology preview for SPARC that Oracle VM manager can discover LDoms already on your SPARC systems; the degree to which you can then actively manage those domains through the manager will be explained at time of release. There is a requirement to add some management agent bits to your existing server, and that your control domain is running S11. Best thing customers can do now is start moving their control domains and IO service domains to S11 in preparation not just of the Oracle VM Manager (and in general better management capabilities), but also for new advanced feature support. You can keep your application domains running S10. 
John, thank you for the detailed response, and for the advice about updating non-guests to 5.11.
I look forward to seeing more about the new VM Manager. -cheers, CSB 
Hi Craig
... will manage sun4v hosts with multiple I/O domains ...I vote for KISS "keep it simple ..." and only one control and I/O domain.
As we all know Solaris is very stable. The only downtime of the control domain should be
when patching or for hardware/fw maintenance. With LDOM 2.2 just migrate the
guests live to another hardware, then you have time for maintenance.

EPM License Tracking

Anyone have ideas on how to best administer this for v11.1.2.x?
I have some ideas that we've been looking to implement, but I was hoping for a more comprehensive way to audit the licenses in use for EPM products, so we are compliance with Oracle.
Any recommendations would be welcomed.
Thanks in advance!
-Ed Puente 
There are two main licensing methods.
1) Named User; managing this is as simple as having a running total of provisioned users vs. number of purchased licenses. If you are concerned about people not using the system that can be managed in later versions 11.X with turning on shared services auditing and pulling reports and then going through an internal process to confirm that users which have not apparently accessed the system no longer require access.
2) Processor; a processor licenses is usually fairly expensive however if you have very fast hardware in conjunction with weight weight application this may be more economical than named users licensing.
Hope this helps,

Upgrading Oracle NoSQL - Minimum Cache size increased from 16 MB to 22 MB

Hello. Just in case somebody runs in the same problem, I upgraded from 1.2.123 to 2.0.22, community version, and had only one error related to the cache size, which is now set at 22 MB at least (I had 16 MB). The node was unreachable via ping, the error was indicated in the file /var/kvroot/mystore/log/sn1_0.log. Once I changed the value in config.xml and restarted, the node was up again. Reaching the store via old scripts with the new .jar files seem to work, I have not tested everything though.

Jesus,
Thank you for posting your note. Apologies that this wasn't highlighted in the Release Notes or Change Log -- we'll add an update to mention this change.
I'm the Product Manager for Oracle NoSQL Database and I'd love to learn more about how you are using NoSQL DB. When you have a chance, can you please contact me at dave a dot and then segleau at oracle a dot and com. Thanks! 
Jesus,
I wanted to correct the earlier response. We have not (intentionally!) increased the minimum cache size requirement in NoSQL 2.0, but we have changed a variety of defaults, and the recommended way of setting memory sizes. In NoSQL 1.0, we asked the user to explicitly set JVM heap size, and the underlying BDB JE cache size, using Replication Node parameters. In NoSQL 2.0, we tried to make these settings more sensible and easier for the user to manage.
We take the approach that the user should set the new Storage Node parameter, memoryMb, described here: http://docs.oracle.com/cd/NOSQL/html/AdminGuide/setstoreparams.html#storagenodeparameters. Now, Replication Node cache size and heap size should be calculated by NoSQL DB, as a function of the memory available on the Storage Node, and the number of Replication Nodes hosted by that Storage Node, rather than requiring the user to set those values. This is intended to make setup easier for the user. And since NoSQL 2.0 supports elasticity, and lets the topology of the store change, it makes the system able to dynamically adjust if the number of Replication Nodes on the Storage Node changes. If the user has not set memoryMB, we attempt to query the JVM for the amount of memory available on that node.
I must also apologize that the current version of our Admin Guide doesn't make this clear at all. We are in the process of revamping the Chapter 2 planning section, which contradicts the new approach. A user really has to read the doc in depth to understand this change in memory sizing, and we are working to make this better!
In the meantime, can you give me more information about your setup, so I can validate that my assertion is true, and that we still support the 16MB size? That would let me make recommendations about which of the new parameters to change, in order to be able to use 16MB (or would reveal a problem I want to know about!). I'd like to know:
- what NoSQL DB parameters you set in your deployment
- the available memory on your Storage Node
Thanks for your help,
Linda 
Linda,
Thanks for your Post. No problem, I setup only a Oracle NoSQL DB in a (dedicated) bigger machine (16 GB RAM) under CentOS running many other things; I try to minimize everything so that resources are consumed only if needed and not by default. The database was upgraded from 1.2.123, the cache size of 16 MB was hardwired in the store, the new requirement was not part of the upgrade, that's all. Same thing happened (obviously) in different virtual machines with other operating systems under VirtualBox.
My 2 cents, your Admin Guide is by far one of the best documentations you can find for databases; your docs are straightforward and also including other domains I tend to read like programming languages or content management systems, your Oracle NoSQL docs would still get a 1+ from me. Whoever wrote it had before a course of "the user does not want to think, the user wants to use it". IMHO: very good. 
Hello Jesus,
On behalf of the NoSQL DB development group, I wanted to thank you for your kind words regarding the excellent quality of our documentation. We very much appreciate that.
Thanks and warm regards.
