Oracle in Three in One Cloud : PaaS, SaaS, DaaS

Khanderao Kand - Thu, 2011-10-06 18:06
After adverse comments last year, Larry Ellison announced that Oracle got into Cloud in a big way. It is significantly different than CRM on Demand. It also adopts different approach than Multi-Tenant Sales Force. Oracle's public Cloud provides: PAAS (Platform As A Service), SaaS (Software As A Service) and Daas (Database As a Service). It has five components:

* Oracle’s Fusion Applications (HCM and CRM) SaaS
* Oracle Fusion Middleware : PaaS
* Oracle Database : DaaS
* Sun Systems, OS, VM : PaaS
* Social Network : SaaS

This announcement puts Oraccle in competition with Amazon, and Salesforce, which are the clear leaders in the public cloud computing space.

Good to see that CRM and HCM are in the pack. Last year I helped CRM and earlier Talent management from HCM in this initiative. This puts Oracle in direct competition with SalesForce, WorkDay and SuccessFactor (on Talent management side).

Oracle also announced Social Network for enterprises. It would allow social networking featers like sharing and following private to enterprises. Does it sound like Salesforce's Chatter? While on the topic of SalesForce, the approach Oracle for most of the component is virtualization based where every customer gets its own pack and not sharing with others as in multi-tenant softwares like SalesForce. This addresses someof the privacy concerns. Enterprises can customize the cloud based Fusion apps by SOA , BPEL, BPM and ADF standards based Fusion Middleware. Oracle's Database as a Service is in competition with similar provision on Amazon.

Oracle also provides Java stack as PaaS in competition with VMWare's CloudFoundry, Redhat's OpenShift and Salesforce's Heroku.

According to Ellison, Oracle’s new public cloud will be available for a monthly subscription and will include resource management and isolation, security, data exchange and integration, self-service sign up, elastic capacity on-demand, virus scanning, and more.

However, pricing and availability is yet to be announced.

OTBI vs. OBIA

Dylan Wan - Thu, 2011-10-06 14:49
Several people are curious about what are OTBI and OBIA, and what are the differences between OTBI and OBIA. I will discuss these in this article.OTBI stands for Oracle Transactional Buisness Intelligence. OBIA stands for Oracle Business Intelligence Applications.Let’s start with OBIA. OBIA is the pre-packaged BI Apps that Oracle has provided for several years. It is the data warehouse based solution. It is based on the universal data warehouse design with different prebuilt adapters that can connect to various source application to bring the data into the data warehouse. It allows you to conslidate the data from various sources and bring them together. It provides a library of metrics that help you measure your business. It also provides a set of predefined reports and dashboards. OBIA works for multiple sources, including E-Business Suite, PeopleSoft, JDE, SAP, and Fusion Applications.OTBI is different. First of all, it is a real time BI. There is no data warehouse or ETL process for OTBI. Second, it is for Fusion Apps only. OTBI is leveraging the advanced technologies from both BI platform and ADF to enable the online BI queries agains the Fusion Applications database directly. In addition, in some area, such as Financial, you can also connect to the Essbase cubes. Unlike OBIA, OTBI does not have a lot of prebuilt dashboards and reports. The reason is that for some advanced analysis, the data need to be prepared. You cannot get eveything you can get from the OBIA data warehouse in OTBI. Both OTBI and OBIA are available from the same metadata repository. Some of the repository objects are shared between OTBI and OBIA. It was designed to allow you have the following configurations: OTBI Only OBIA only OTBI and OBIA coexistIf you implement Fusion Apps, you can enable OTBI. You can use the BI EE Answer to access the prebuild metadata and metrics those are built against the Fusion Apps. You may not get the full powerful prebuild dashboard and repost and prebuilt navigation workflow. However, you can start experiencing what the BI EE based reports look like. You can start bring the data out from your OLTP system. You can provide training to the users to get familar with the subject areas, some of which are shared with OBIA. If you enjoy OTBI and want to further get OBIA with a data warehouse based solution. You can implement OBIA later. Some of the OTBI reports maybe switched to run against OBIA. Some of OTBI reports can continue connecting to Fusion Apps directly. They can coexist in a single BI server and a single BI answer client.Both OTBI and OBIA are accessing Fusion Apps via the ADF. This is a more advanced topic.

Oracle NoSQL Database vs Berkeley DB Java Edition

Charles Lamb - Thu, 2011-10-06 06:34

I've been watching the twitter-sphere for comments about Oracle NoSQL Database.  There are a number of common questions and misconceptions floating around that I'll address here:

Misconception #1: "Oracle NoSQL Database is just Berkeley DB Java Edition rebranded."; "Oracle NoSQL Database sounds like it's just Berkeley DB with extra bits."

When we built NoSQL Database, we recognized that Berkeley DB Java Edition HA provided us with lots of necessary, but not sufficient, elements for a NoSQL store.  For instance, JE/HA gives us:

  • ACID Transactions
  • Persistence
  • High Availability
  • High Throughput
  • Large Capacity
  • Lights out administration

And you could even argue that its key/value data model is already "NoSQL".  But we believe that NoSQL means something more to most people.  Like

  • Data distribution
  • Dynamic partitioning (aka "sharding")
  • Load balancing
  • Monitoring and Administration
  • Predictable latency
  • Multi-node backup

So although NoSQL Database is built using BDB JE/HA as the underlying, battle-tested, storage system (why reinvent the wheel?), NoSQL Database adds a large amount of infrastructure on top of it to bring it into the NoSQL realm.  As my colleague Chao Huang says, "BDB JE is like an engine. NoSQL Database is the car built with the engine."

Misconception #2: "Oracle NoSQL Database has the same API as Berkeley DB Java Edition"

I realize that at the time of this writing we have not released the software so the reader has no way of looking at the javadoc to see the actual NoSQL Database API, but suffice it to say that the API is not the same as BDB JE.  The interface is Java, and it provides CRUD, iteration, and CAS (aka "RMW") capabilities on key/value pairs.  There is also a major/minor key capability.  All key/value pairs with the same major key reside on the same "Rep Group" (a Rep Group is just a BDB JE HA replication group of a master and N replicas).  That way, records can be clustered (e.g. put all records related to "Fred" on the same node).  One other (slight) difference between the BDB JE and NoSQL Database APIs is that the former uses byte[] for keys and the latter uses Strings for keys.  Both use byte[] for the data portion.

(Non-) Misconception #3: "Oracle is adding network bindings to Berkeley DB Java, branding it Oracle NoSQL. I am curious how easy setup and develoment will be."

Let me address the second question first (ease of setup/development).  Although this isn't a misconception, it is a good question.  In general it is difficult for the average developer who wants to try out a large distributed store to find sufficient hardware to get a reasonable sized cluster going.   Well, maybe it's difficult not for you, but it sure is for all of us -- we have to claw and scratch for every machine we use(*).  So George (one of developers) put together what we call "kvlite", a single process version of Oracle NoSQL Database.  kvlite is really easy to start up (one simple command line invocation) and gives the user a good way of trying out the API without a lot of muss and fuss.  The "server side" is in no way tuned for performance, but it lets you get things going really quickly so you can kick the tires, try out your application code, etc. while your sysadmins and IT folks scrounge the real hardware for you to use for deployment.

(*) We actually have several large clusters to do development and performance testing at our disposal.

And now the first part of the question (adding network bindings to Berkeley DB Java Edition).  Hmm, that's kind of, sort of true.  Let me try to reframe the statement.  BDB JE HA allows a user to perform operations on either the master (for updates and reads) or the replicas (for reads).  The most common objection that we encounter is that the application has to "know" which nodes are the master and the replicas (for routing updates and read requests appropriately).  There is no network layer in BDB JE/HA to handle this for you.  Oracle NoSQL Database provides this capability.  You link in the kvclient.jar (the "driver") to your application, and presto, you can make your CRUD (or iteration) method calls on your K/V Store.  The kvclient.jar figures out which node to route the request to (it knows which Rep Group holds the key value pair and which node in that Rep Group is the master).  So in that sense, it adds a network layer to BDB, but the API is different from BDB so I wouldn't exactly call it a network binding.  There's a lot of infrastructure and intelligence (e.g. load balancing) built into the kvclient "driver".

How big is your data?

Andrews Consulting - Wed, 2011-10-05 12:27
After two days OpenWorld could be called Oracle Hardware World since “engineered systems” is all that Oracle executives seem to want to talk about. The only other topic that has gotten any serious airtime so far is “big data”. A huge sign by the entrance to the main presentation hall declares: Oracle is big data. […]

Multi Byte String Generator

Peter O'Brien - Wed, 2011-10-05 11:27
Click to go to launch page.Fusion Applications uses Oracle Data Integrator as part of the data bulk import feature which includes migration and file import. While working on the Opportunity Bulk Import we had to ensure that multi byte characters were imported correctly. The majority of the test data we had to work with was from Siebel demo data used in North America. As a consequence, most of the data was ASCII and single byte. Just so we could generate multi byte strings for developer testing I put together a little Java Web Start application called Multi Byte String Generator.

It has a simple interface where you specify the number of bytes you want per character (1 to 3) and what the number of characters you want. The randomly generated string is displayed and you can copy it to your clipboard (using the Copy to Clipboard button) and paste it into your application or test fixture. Due to the security features of Java Web Start, you will be prompted to allow the application to access your local clipboard. Some additional information about how many bytes the string occupies in UTF-8, UTF-16 and UTF-32 encoding is also displayed.

We have a lot of hardware up here!

Oracle NoSQL Database

Charles Lamb - Mon, 2011-10-03 07:27

Today at Oracle OpenWorld, we are announcing Oracle NoSQL Database.  From the datasheet:

Oracle NoSQL Database provides network-accessible multi-terabyte distributed key/value pair storage that offers predictable latency. That is, it services network requests to store and retrieve data which is organized into key-value pairs. It offers full Create, Read, Update and Delete (CRUD) operations, with adjustable durability guarantees.  Oracle NoSQL Database is designed to be a highly available and extremely scalable system, with predictable levels of throughput and latency, while requiring minimal administrative interaction.

My colleagues and I have been working hard to bring this project to fruition and it's truly exciting for all of us to see it roll out the door (as well as to be able to finally talk about it in public).  It will come in two versions, an Open Source Community Edition, and a value-add "Enterprise Edition".  Initially, both Editions will have the same feature set, but in subsequent releases there will be differentiation between the two. My colleague Margo Seltzer has written a fine whitepaper which describes the system.  If you have the time, it's an easy read.

In future posts to this blog I hope to talk about some of the great performance and scaling numbers we're seeing in our tests.  To demonstrate the system's capabilities, we've been working with two very fine corporate partners to run tests on clusters of up to 192 nodes.

We also announced the Oracle Big Data Appliance, an "engineered system" which will run (among other things) Oracle NoSQL Database.

Long time no post

Marcelo Ochoa - Mon, 2011-09-26 08:41

I found that my last post was on Sep. 14 2010, that's too bad.
The reason of that is the startup called Scotas I worked on that almost since December of 2010 to engineering a next level of Oracle and Lucene project integration, this is by adding the Solr stack.
Its a natural evolution, Solr provides a lot of common functionality working on top of  Lucene required for the enterprise level solution.
But the integration required a set of implementation challenges to work, once of them is the implementation of long live shared server process running in Java and which implements a new dedicated HTTP listener working as an Oracle slave process, I will explain this topic on another technical post.
Another additions included in a set of products are the push technology spread on the integration with Solr running externally, ElasticSearch, Cassandra and HBase.
Behind this technology we extended the idea of Oracle/Solr integration, the Oracle ODCI API,. which enabled a NRT (Near Real Time) synchronization of the enterprise data with NoSQL layer for example.
Near Real Time means that once you commit the changes on the RDBMS layer thy are propagated automatically to the other side practically with 0 delay, and for the two way replicator such as Solr PC and ElasticSearch deletions are in real-time avoiding the false positive hits of deleted rows.
Near Real Time synchronization is declarative, no programming effort is required and allows multiples columns of one table, or multiples columns of many tables connected by a foreign key.
Well next week is the OOW 2011, I'll Be there and I Hope You Will, Too and for anybody that are coming to the event and are interested on that technology we could meet there, just drop me an email to mochoa-at-scotas.com

EXISTS

Rob van Wijk - Sun, 2011-09-25 05:03
Most of us know the SQL keyword EXISTS as the condition with a subquery you use in a WHERE clause. But if you look at the documentation of EXISTS, you'll see that it says nothing about just using it in a WHERE clause. It's just a sort of function that accepts a query as input and returns "TRUE if a subquery returns at least one row". The SQL language doesn't know about booleans, but it calls Rob van Wijkhttp://www.blogger.com/profile/00499478359372903250noreply@blogger.com2

Rise of the appliances?

Freek D’Hooge - Thu, 2011-09-22 02:52

Some quick thoughts.

Yesterday Oracle announced it’s first database appliance for th SMB market.
Before this, it had already its Exadata and Exalogic appliances for the big environments.
During the presentation Oracle has also indicated that it want’s to continue delivering new appliance products and apparently is no longer interested in selling “commodity” x86 servers.

Symantec has also been busy with appliances for Netbackup.

For some time now, we have seen that the big players in the IT market are leaving their historical background and are trying to offer the complete stack from software over switches to storage. Is this offering of appliances the next step?
Will we see more and more applications offered as appliances?

If so, what will this mean for the independent system integrators?

Also, as these appliances seems to use their own dedicated storage, what does this mean for the SAN?
(I know of some people who will not mourn there decline).

Oracle APEX (Application Express) Built-in LDAP Test Tool Stand-alone Application

Ittichai Chammavanijakul - Wed, 2011-09-21 18:56

Oracle APEX provides multiple ways for authentication. The most commonly used one is the LDAP authentication. Configuring it is very straight-forward in most cases – just providing the LDAP host, port, whether or not to use SSL, and finally the DN string. See here and here for posts about APEX LDAP configuration.

Sometime you want to test the LDAP configuration before deploying it. You can either use the 3rd-party tools to validate the configurations, or create an APEX application to test the logon, or use the built-in LDAP test tool in APEX.

The built-in APEX LDAP test tool can be launched when the authentication is being configured as seen below.

LDAP Test Tool

It will pop-up a new window as shown below.

LDAP Test Tool Pop-up Screen

By accident, I found out that you can even launch the APEX LDAP Test Tool as the stand-alone application using Application ID 4000 and Page Number 3890.

For example,

http://localhost:8888/apex/f?p=4000:3890

It will obviously prompt you to log on to the workspace first, then the LDAP test tool will just show just like an application, not the pop-up window.

Oracle anounces the Unbreakable DB Appliance

Freek D’Hooge - Wed, 2011-09-21 12:33

More then 10 years after Oracle’s first appliance attempt with Raw Iron and 3 years after the release of Exadata, Oracle has now announced the Unbreakable DB Applicance.

This “cluster in a box” consists out of a 4 RU chassis, in which 2 server nodes,  96 GB memory per node, 12 TB raw shared disk storage  (24 disks) and 292 GB flash disks has been placed.
The two server nodes have a total of 24 cpu cores, but cores can be disabled.
This allows for sub-capacity licensing of the software (with a minimum of 4 cores).

On the software side, the appliance is running Oracle linux and 11gR2 grid infrastructure and 11gR2 db software. Databases on this appliance can run as single node, RAC or RAC One Node.
Oracle enterprise manager is also part of the software stack.

Claims are made towards one button installation of software and patching.
The appliance has also a “phone home” functionality which automatically creates a service request when a problem is detected.

List price for the hardware is $ 50,000 (regardless of how many cores you activate) and for the software the standard DB licensing applies.
Which means that existing CPU licences can be transferred to this appliance.

Oracle positions this system below the Exadata quarter rack, and it is also worth mentioning that this appliance is not expandable.

So far the product launch information.

Some questions / remarks I have:

  • According to the presentation the hardware price remains the same, regardless of how many cores you activate (namely $ 50,000).
    In my opinion, this means that no one will buy this appliance to just activate 4 cores.
    There are much cheaper solutions when you only need a low number of cores (certainly when you consider that most companies already have a san which can be used for the Oracle databases)
  • There are 24 disks in the appliance, which seems low (certainly compaired to the 24 cpu cores).
    However, keep in mind that this storage is dedicated and probably (I don’t have confirmation on this) capable of asm intelligent data placement and command queuing.
    Normally SAN vendors are using an estimate of 180 IOPS per san disk. Oracle however is using an estimation of 300 IOPS per cell disk for Exadata, and tests done by Glenn Fawcett show that they can actually perform even better (around 400 IOPS).
    http://glennfawcett.wordpress.com/2011/05/10/exadata-drives-exceed-the-laws-of-physics-asm-with-intelligent-placement-improves-iops/
    Using the number of 300 IOPS, this would mean that the 24 disks translate to 40 SAN disks (that may not used by any other application, so in reality to even more san disks), which already looks very different.Now, I’m still unsure how it will perform with write intensive databases (oltp or dwh), certainly when several databases are consolidated on this appliance.As this appliance is not expandable, the number of disks may be a weak point, compaired to the number of cpu cores.
    I’m hoping that someone like Kevin Closson (poke poke) will be able to shed some light on this, as my knowledge in this area is rather limited :-)
  • In the presentation it was mentioned that the flash storage is used for the redo logs, but it is unclear if it could also be used to store datafiles or as cache (as with the Exadata smart flash cache)

As with many things the proof of the pudding is in the eating, so I’m looking forward to some benchmarks and presentations by real world customers.
And if anyone from Oracle is reading this, you may always send me a demo machine so I can do some testing on my own  ;-))

update 20:12, fixed wrong memory specification
