Oracle #GoldenGate Parameter File Templates

This week I’ve been enjoying spending some time at Oracle Open World in San Francisco, CA.  While here, I’ve been talking with everyone, friends old and new, and it came to my attention that it would be a good idea to have some useful templates for Oracle GoldenGate parameter files.  With this in mind, I decided to create some generic templates with comments for Oracle GoldenGate processes.  These templates can be found on my Scripts (more...)

New: Oracle Cloud Adapter SDK

A cool thing I heard at Open World 2014: we all know in SOA there are all these adapters you can use in your SCA components. In Oracle Integration Cloud Services (ICS) there are a lot of new SaaS adapters to integrate with SaaS applications like SalesForce for example. These adapters are build using a Cloud Adapter SDK and written in Java.

This exact SDK will be available for users as well, so we all (more...)

ADF and service dependencies

In order to keep the business-IT gap manageable, it is important for analysts, designers and architects to know what their implemented application landscape actually looks like. An important part of this is insight in dependencies between different components. In my previous blog post I’ve described how service dependencies can be determined. In this blog post I will provide a script for analyzing which services are called by ADF pages. Keep in mind both analyses are executed on (more...)

JSON is flowing through SOA’s veins

This year’s Oracle Open World is again all about Cloud and Mobile. However, this year it is getting more and more concrete. Apart from all the announcements of Process Cloud and integration cloud services there will be more JSON support in Oracle’s SOA Suite.

In Oracle SOA Suite 12C (12.1.3) the REST Adapter already made its appearance. This adapter makes it make your SCA component available as, and leverage REST services, using JSON. (more...)

When to use the Oracle Database In-Memory option?

The application and usage of the Oracle Database In-Memory has been described by Pom Bleeksma in this post. Oracle Database In-Memory can result in huge improvement in application query performance. This post will answer the question: “what would be an optimal situation for using the Oracle Database In-Memory feature?” The most predictable answer for these kind of questions is “it depends”. It is advisable to consult an expert before investing in this feature since (more...)

Partitioned Clusters

In case you hadn’t noticed it, partitioning has finally reached clusters in 12c – specifically 12.1.0.2. They’re limited to hash clusters with range partitioning, but it may be enough to encourage more people to use the technology. Here’s a simple example of the syntax:


create cluster pt_hash_cluster (
        id              number(8,0),
        d_date          date,
        small_vc        varchar2(8),
        padding         varchar2(100)
)
-- single table
hashkeys 10000
hash is id
size 700
partition by range (d_date) (
        partition  (more...)

12c In-Memory on RAC

I started looking into In-Memory on RAC this week. Data can be distributed across RAC nodes in a couple of different ways. The default is to spread it across the available nodes in the cluster. So if you had a 2 node cluster, roughly 50% of the data in your table or partition would be loaded into the column store in each of the 2 instances.

Change unknown SYSMAN password on #EM12c

When I normally start work on a new EM 12c environment, I would request to have a userid created; however, I don’t have a userid in this environment and I need access EM 12c as SYSMAN.  Without knowing the password for SYSMAN, how can I access the EM 12c interface?  The short answer is that I can change the SYSMAN password from the OS where EM 12c is running.

Note:
Before changing the SYSMAN password (more...)

12c In-Memory in PDB

In preparation for our upcoming 12c In-Memory Webcast @CaryMillsap, @TanelPoder, and I solicited questions from members of the universe at large on the interweb. We got a question about how In-Memory works with the 12c multi-tentant option and it got me thinking so I gave a quick try. As it turns out, it works about as you would expect. The basic idea is to turn it on for the container DB (which is where the (more...)

ORE now available for Multitenant (PDB) version of 12c

Adding additional agents to OEM12c

One question I get asked a lot is “how can I add additional agent software to OEM 12c”?  The answer is pretty easy; just download and apply to the software library.  Now what does that mean?  In this post, I’ll explain how to download additional agents for later deployments to other platforms.

After logging into OEM 12c, go to the Setup -> Extensibility -> Self Update (Image 1).

Group By Bug

This just in from OTN Database Forum – a surprising little bug with “group by elimination” exclusive to 12c.

ADF EMG Audit Rules available on JDeveloper 12.1.3

I got a few questions from people why the ADF EMG Audit Rules are not available in JDeveloper 12.1.3. So there has been a new release of the ADF EMG Audit Rules. No new functionality is implemented this time, but the extension is now available for JDeveloper 12.1.3.

If you go to Help -> Check for Updates, tick the Open source and Partner Extensions checkbox and press Next:

The Next Big Thing

Oracle’s 12.1.0.2 was released a few weeks ago (You can download it from OTN here: Oracle 12.1.0.2 Download). While technically a minor point release, it contains a couple of major features that would normally be rolled out in a more substantial version change like 12cR2 or perhaps V13. Of course the most highly anticipated feature is a new option (Oracle In-Memory Option) that provides a column (more...)

12.1.0.2 Introduction to Attribute Clustering (The Division Bell)

One of the really cool new features introduced in 12.1.0.2 is Attribute Clustering. This new table based attribute allows you to very easily cluster data in close physical proximity based on the content of specific columns. As I’ve discussed many times, indexes love table data that is physically clustered in a similar manner to the index […]

Integrated Application Heartbeat for Oracle GoldenGate

Over the last two weeks I’ve been working on a heartbeat monitoring solution for a client.  This is not the normal heartbeat solution provided by Oracle as described in note 1299679.1; yet very similar.  The approach that I configured is similar to a traditional heartbeat setup but uses the same extract and replicats already being used by the database/application.  For simplicity reasons, I like to call this approach an Integrated Application Heartbeat.

Making the CDB Common User Without Using C## Prefix….

If you have done any play with the latest release of Oracle database 12c, you must have come across the concept of Common and Local users. I won’t rewrite what’s already there in the docs but for setting the context of the post, a Common user must be created with a prefix added to the username-C##. Miss that and you won’t be able to create one while being connected to the Container database. On (more...)
