How to deploy from your Developer Cloud Service to JCS

One nice aspect of the Developer Cloud Service is that you can automate deployments as part of your continuous integration process - thus simplifying overall DevOps.

In order to directly deploy to an instance of Oracle Java Cloud Service (JCS) there are some security requirements that you need to take into account.

For details on how to get those pieces of information (such as your private key for your JCS instance) see the blog entry here:

Kscope15 – It’s a Wrap, Part II

Another fantastic Kscope in the can.

This was my final year in an official capacity which was a lot more difficult to deal with than I had anticipated. Here's my record of service:
  • 2010 (2011, Long Beach) - I was on the database abstract review committee run by Lewis Cunningham. I ended up volunteering to help put together the Sunday Symposium and with the help of Dominic Delmolino, Cary Millsap and Kris Rice, (more...)

Neue SQL Plan Operationen und Hints in 12c

Sayan Malakshinov hat sich die Mühe gemacht, eine kommentierte Link-Liste zu den in 12c eingeführten SQL PLAN OPERATIONS und Hints zusammenzustellen. Das Ergebnis sieht ausgesprochen vielversprechend aus.

ORDER BY CASE

Sometimes I give parts of a solution to increase the play time to solve a problem. I didn’t anticipate a problem when showing how to perform a sort operation with a CASE statement. It’s a sweet solution when you need to sort something differently than a traditional ascending or descending sort.

I gave my students this ORDER BY clause as an example:

  CASE
    WHEN filter = 'Debit' THEN 1
    WHEN filter = 'Credit' THEN 2
     (more...)

Static File not updating in runtime Apex environment

The UAT environment is a runtime Apex installation (4.2.4.00.08) and all deployments are done via SQL scripts. My application uses a small number of static files that for convenience we are serving from Apex (at least for now); to deploy changes to these static files, I export f100.sql and static_files.sql from Apex in dev and we run them in the target environment after setting a few variables, like this:

declare

Longer names coming to Oracle?

Have you ever, like me, been silently finger-counting the number of characters in a table name, column name or procedure name that you are about to create in the Oracle Database, to make sure it is short enough? It appears those days will soon (?) be at an end...

The current limit on names (identifiers such as table names, column names, procedure names, parameter names, etc) in Oracle SQL and PL/SQL is 30 characters. (more...)

Insert-Sortierung und Index-Größe

Mal wieder ein Titel, der den Eindruck erweckt, dass vielleicht eine größere Präzisierung möglich gewesen wäre - aber da Richard Foote dem Artikel, den ich hier wiedergebe, den Titel Why A Brand New Index Might Benefit From An Immediate Coalesce (One Slip) gegeben hat, fühle ich mich nicht dazu verpflichtet, länger darüber nachzudenken. Worum es geht, ist Folgendes: der Herr Foote zeigt in seinem Blog, dass ein Index auf einer via Insert as Select befüllten (more...)

I/O-Performance in Datenbanken und auf OS-Seite

Auf Oracle-L hat Stefan Koehler heute einen interessanten Link zum Thema "Kommunikation zwischen DBAs und Storage-Administratoren" untergebracht: im referenzierten Artikel erläutert Bart Sjerps, dass beide Gruppen oft von unterschiedlichen Dingen sprechen, wenn sie über I/O-Performance diskutieren: während die Storage-Admins die reine Service time vor Augen haben - also die Zeit, die die Storage selbst benötigt, um einen einzelnen I/O request zu beantworten (= die von iostat ausgegebene Spalte svctm) -, interessieren sich die DBAs (more...)

ODTUG Kscope15 Review: It was the best of times, it was the best of times!

Last week AuraPlayer headed south to attend ODTUG’s annual KScope conference in Hollywood, Florida. It was very exciting to play many pivotal roles; serving as an ODTUG Board member, an Exhibitor, a 2 time speaker and an Oracle ACE Director. The event was definitely a highlight – I truly learned a lot and, of course, had a lot of fun.

With that being said, so much happened that it would be nearly impossible to provide an (more...)

Conditional Compilation and Static Boolean

One of my pet-projects is LoggerUtil, which is a utility for Logger, which is an excellent logging tool for PL/SQL.
This post is not about Logger, but some dealings with Conditional Compilation.

With Conditional Compilation you can create a single code base to handle different functionalities depending on compiler flags.
The latest addition to LoggerUtil was a method to create a custom template. For this to work, LoggerUtil depends on a certain Logger Release (where (more...)

Splitting a Table into Rowid Ranges of Equal Size

In the OTN forum, Jonathan Lewis recently asked for an efficient SQL solution to split a table into 12 ROWID ranges having the same (+-1) number of blocks. I'm posting here a slightly cleaned-up version of my answer so I can change it if necessary after the question gets archived.

Leveraging the Oracle Developer Cloud from Eclipse

Permanente Deaktivierung einer SQL Plan Directive

Franck Pachot erklärt, wie man dafür sorgt, dass eine SQL Plan Directive dauerhaft deaktiviert bleibt, um den Overhead des Samplings zu vermeiden. Das Problem dabei ist, dass die Direktive nach einer vollständigen Löschung erneut erzeugt werden kann. Um das zu verhindern, muss die Direktive deaktiviert, aber ihre Löschung verhindert werden - die Befehlsfolge dazu lautet:

exec dbms_spd.alter_sql_plan_directive(14130932452940503769,'ENABLED','NO');
exec dbms_spd.alter_sql_plan_directive(14130932452940503769,'AUTO_DROP','NO');

Grundsätzlich sind die Direktiven jedenfalls ein Thema, das man für 12c klar im Blick behalten muss.

Make Tabular Form Conditionally Read-only

If you decide to use an editable tabular form to present a number of records for viewing and/or editing, but you have some users who are only allowed to view the data but not edit it, you’d think you could set the “Readonly” condition on the region; but this condition is only applied to any extra region items you add, not to the editable items within the report itself.

Here’s my tabular form, with the records (more...)

Fix completion insight in JDeveloper 12.1.3: show return type again

Hi!

If you work with JDeveloper 12.1.3 you may missing the return type of methods in completion insight.

For an example you hit CTRL-SPACE after following code

completion_insigt_return_type_wrong

you see that at the start and at the end of the popup the available method names and parameter. If you have worked before with older versions of JDeveloper, you know that there is shown the return type of the method at the end. What a loose of (more...)

Cardinality Schätzungen für TEMP TABLE TRANSFORMATION

Randolf Geist hat vor einigen Wochen in zwei Artikeln weitere Details zum Verhalten der Cardinality-Schätzungen im Rahmen der TEMP TABLE TRANSFORMATION geliefert - in Ergänzung zu zwei (geringfügig) älteren Artikeln, die ich hier gelegentlich verlinkt habe und in denen vor allem darauf hingewiesen wurde, dass die Transformation nicht kostenbasiert ist, sondern automatisch angewendet wird (sofern die erforderlichen Voraussetzungen erfüllt sind), dass sie zu einer Materialisierung aller Spalten der CTE führt - und nicht nur der tatsächlich (more...)

ODCI dynamic table function parser

Supposing you've got data as a text string with "row" and "column" delimiters and you would like to parse out those columns and rows. The external table syntax would actually be great for this, but that requires writing the text out to a file first, and then you can import it back again as columns and rows.

There are various other alternatives using SQL and/or XML manipulations, but one method that I don't see much (more...)

Epoch

Note to self because it’s just one of those date/timezone-related topics which just doesn’t seem to stick…

Epoch/Unix time – See https://en.wikipedia.org/wiki/Unix_time

Unix time (also known as POSIX time or erroneously as Epoch time) is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970,

Firstly when converting from Oracle date or timestamp – we need to (more...)
