EM13cR2 Installation Failing on BI Publisher Configuration

This is going to be a short post as there wasn’t much information on this type of failure when searching for it. Also, the IP’s are changed due to security reasons

I was working on an Oracle EM13cR2 installation and when the installation reached 78%, it failed on the BI Publisher configuration. First, I looked at the CfmLogger log.

Moving to the Cloud Made Simple: A Framework for Oracle e-Business Suite in AWS 

We wouldn’t blame you if you’re not 100% ready to jump into the Cloud, just because that’s what everyone else seems to be doing. Making the right decision for your business means taking a careful look at what exactly the benefits are going to be. How will your systems work in the Cloud? Can Cloud providers like AWS actually meet your (more...)

Using DataGuard broker to show apply lag and throughput

To determine how much lag there is I normally run a script similar to this

select sequence#, applied, to_date(to_char(first_time,’DD-MON-YY:HH24:MI:SS’),
‘DD-MON-YY:HH24:MI:SS’) “First Time” ,
to_char(next_time,’DD-MON-YY:HH24:MI:SS’) “Next Time”
from v$archived_log
UNION
select NULL,database_role,NULL, db_unique_name from v$database
order by “First Time”;

However there is another way which I sometime use which actually gives a lot more information. This uses the dataguard broker command line. Use the show configuration parameter to determine database name if you are not sure

OGh Tech Experience 2017 – recap

On June 15th and 16th 2017 the very first OGh Tech Experience was held. This 2-day conference was a new combination of the DBA Days and Fusion Middleware Tech Experience that were held in previous years. To summarize: OGh hit bullseye. It was two days packed with excellent in-depth technical sessions, good customer experiences and great networking opportunities.

The venue was well chosen. De Rijtuigenloods in Amersfoort is a former maintenance building of the Dutch (more...)

Oracle SQL Strip Quotes

Somebody wanted to know how to strip double quotes from strings. Obviously, they’re playing with the DBMS_METADATA package. It’s quite simple, the TRIM function does it, like this:

SELECT TRIM(BOTH '"' FROM '"Hello World!"') AS "Message"
FROM   dual;

It will print:

Hello World!

As always, I hope this helps those looking for a solution.

JDBC, Linux and Entropy

Some troubles — especially those happening only sporadically — are not so easy to shoot and call for a deeper understanding of the matter. In the following real-world example this means: SQL*Net Tracing and some knowledge about the inner workings of the server’s operating system, particularly random number generation. This case was suited well to demonstrate an approach to trouble-shoot […]

Introduction to Oracle Big Data Cloud Service (Part IV) – Zeppelin

This is my forth blog post about Oracle Big Data Cloud Service. In my previous blog posts, I showed how we can create a big data cloud service on Oracle Cloud, which services are installed by default, ambari management service and now it’s time to write about how we can work with data using Apache Zeppelin. Apache Zeppelin is a web-based notebook that enables interactive data analytics. Zeppelin is not the only way to work (more...)

Notes From Orlando

I thought y'all would appreciate some notes from last week's OHUG conference in Orlando Florida.  So, in no particular order, my observations...
  • The sessions were pretty evenly divided between Oracle E-Business, PeopleSoft and HCM Cloud.  Right around 1/3 of total sessions for each track.
  • The mix of attendees, from what I could tell, were about half HCM Cloud users and half on either EBS or PeopleSoft.  And out of those on EBS or Peoplesoft, about (more...)

Unpivot

An interesting observation appeared recently as a side-channel on a question on the OTN database forum – how does Oracle execute an unpivot() operation. Here’s an example of such a query:

rem     Author:         Jonathan Lewis

Introduction to Oracle Big Data Cloud Service – Compute Edition (Part I)

Over the last few years, Oracle has dedicated to cloud computing and they are in a very tough race with its competitors. In order to stand out in this race, Oracle provides more services day by day. One of the services Oracle offers to the end user is “Oracle Big Data Cloud Service”. I examined this service by creating a trial account, and I decided to write a series of blog posts for those who (more...)

If you’re familiar with SQL Profiles and SQL Baselines you may also know about SQL Patches – a feature that allows you to construct hints that you can attach to SQL statements at run-time without changing the code. Oracle 12c Release 2 introduces a couple of important changes to this feature:

  • It’s now official – the feature had been moved from package dbms_sqldiag_internal to package dbms_sqldiag.
  • The limitation of 500 characters has been removed from (more...)

Last night I decided I ought to demonstrate the claim – so here’s a little code, first (more...)
