Oracle 12c – New SYS-level Administration Privileges

For a while now, Oracle has been moving its security model toward a more differentiated set of privileges than just SYSDBA and SYSOPER.  We saw this in 11g with the SYSASM privilege.  This is in response to the growing number of DBA shops that delineate permissions at a more granular level, even among DBAs.  Rather than saying, “Here’s my DBA team, everyone has SYSDBA,” more and more IT shops are defining DBA (more...)

Quality Assurance for ADF projects

If you speak german and you are interested in quality assurance for your ADF projects you should come and attend my presentation at DOAG Development on 06/04/2014 in Dusseldorf.

I will show you, how you can implement in the JDeveloper IDE and in Continous Integration server Jenkins:

  • static code analysis with PMD, FindBugs and Checkstyle
  • Task’s
  • Commit tests with JUnit, Mockito and Powermock for Mockito
  • Code coverage for commit tests with JaCoCo
  • Acceptance tests with JUnit (more...)

Dynamic Registration In 12c Using LREG….

There is a lot of change that release 12.1 or 12c has brought up. And it’s not in the more advanced new features that I am talking about but even in some areas about which, we have memorized a particular concept by heart from last many years. Once such change is what I am going to mention in this post-introduction of the LREG(Listener Registration) process.

Basics of Dynamic Registration
In the earlier releases,to register (more...)

Indexing Foreign Key Constraints With Invisible Indexes (Invisible People)

In my previous post I discussed when deleting rows from parent tables, how Bitmap Indexes based on the FK constraint can prevent the expensive Full Tables Scans (FTS) on the child tables but not the associated exclusive table locks. Last year, I discussed how it was possible in Oracle Database 12c to have multiple indexes on the same column list. […]

Oracle R Enterprise and Oracle 12c

A few of weeks ago we had the release of Oracle R Enterprise (ORE).

There has been some posts on the R/ORE on the Oracle discussion forums about installing ORE on Oracle 12c.

It turns out that the only way to install ORE on an Oracle 12c database is if you do a traditional install. What this means is that you do not have a CDB and PDBs configuration of Oracle 12c.

I'll assume that (more...)

Oracle ASM 12c: New Features

Last week I was lucky enough to be presenting at the UKOUG AIM SIG. There was a decent enough crowd in attendance and there were some really interesting talks and some really good speakers. In particularly I found Chris Lawless speaking on replication a particularly engaging speaker, and Dave Webster really held the audiences attention late in day.

I was giving a presentation on the new features available to you with 12c ASM. The presentation (more...)

Battling Bigfile Backup Bottlenecks

Last Friday I kicked off a database backup to an NFS destination, using the standard "backup as compressed backupset database" syntax. Loyal readers of this blog may recall that I'm the proud custodian of a 25 Tb database, so this backup normally takes a few days, with an expected completion on Monday morning. However it was still running on Wednesday, and reviewing the logs I saw that there was just 1 channel (of the original (more...)

DBRM for 12c Container Database in Multi-tenant Environment

In multi-tenant environment, Database Resource Manager (DBRM), at the Container Database (CDB) level enables us to manage the resources like CPU usage and number of parallel execution servers among the plugabble databases (PDBs). Then within each PDB, DBRM enables us to manage resources like CPU, parallelism and managing the runaway queries which exceed the certain thresholds of CPU, physical IO, logical IO or elapsed time.

In 12c version of Oracle database, at the CDB level, (more...)

Finally, Oracle has its own Identity!

create table from_12c_onwards (
  you_can_have_your_pk number 
    generated always as identity,
  so_you_dont_have_to_type_it varchar2(10)
);

insert into from_12c_onwards (
  so_you_dont_have_to_type_it
) values (
  'yes'
);

insert into from_12c_onwards (
  so_you_dont_have_to_type_it
) values (
  'Yes'
);

insert into from_12c_onwards (
  so_you_dont_have_to_type_it
) values (
  'YES!'
);

select * from from_12c_onwards;

This week, I wrapped up the Oracle 12c Technical Hands-On workshop in Oracle facility, Gurgaon. It was a 2-day event from Oracle Database Product Management. The focus of the … Continue reading

Modify Primary Key Using Index (Learning To Fly)

One of the things I love about working with Oracle Database technologies is that there’s just so much one can learn. I make it an active goal of mine to try to learn something new at work each and every day, no matter how big or small. One of these days, I might blog about a presentation I put together […]

SQL Developer’s PL/SQL Debugger and Oracle 12c

The PL/SQL Debugger works pretty much out of the box when used with a previous Oracle version. These are the things we needed in place before we could start debugging PL/SQL:

  1. A grant of the DEBUG CONNECT SESSION privilege.
  2. EXECUTE privilege on DBMS_DEBUG_JDWP.
  3. EXECUTE privilege on the stored procedure you want to debug.
  4. Make sure the stored procedure is “Compiled for Debug”.

Jeff Smith talks about it in this post.

But what happens when you (more...)

12c Enhanced Online Index DDL Operations (Lady Godiva’s Operation)

In my last couple of posts, I discussed how table partitions can be moved online since 12c, keeping all indexes in sync as part of the process. 12c also introduced enhancements to a number of index related DDL statements, removing blocking locks and making their use online and far less intrusive. The following commands now have a new ONLINE […]

Clusterware 12c and Restricted Service Registration for RAC

Topic: This post is about exploring the mechanisms used by Oracle Clusterware 12.1.0.1 to restrict remote service registration, i.e. the 12c new feature "Restricting Service Registration for Oracle RAC Deployments"

Why is this useful? This improvement of 12c clusterware and listeners over the 11.2 version is useful mainly for security purposes, for example as a measure against TNS poisoning attacks (see also CVE-2012-1675), and it is particularly relevant for (more...)
