ORAchk (EXAchk) und der Collection Manager (Teil 2)

Nun geht es mit Teil 2 weiter.

Nach dem nun die APEX Installation fertig ist, geht es darum den Collection Manager zu installieren und zu konfigurieren.

Dazu empfehle ich sich für das Setup parallel die Dokumentation, also das User’s Guide „Oracle® ORAchk and EXAchk“ und hier Kapitel 1.9 Oracle Health Check Collections Manager for Oracle“ zu öffnen.

Wir melden uns nun am Admin Service an:

Oracle Developer Podcast – Developer Evolution

podcast-356-dev-evolutionLast month I was fortunate enough to have been invited to participate in another Oracle Developer Podcast.  Rather than focusing on specific technologies, this focused on more how the thew job market is changing for IT and what might be driving change, and how things may change in the future. Check it out here.

As ever thanks to Bob Rhubart of the invitation, and putting together these excellent recordings.

Well, That Didn’t Work …


"There are no wrong roads to anywhere."
-- Norton Juster, The Phantom Tollbooth

Interesting behavior with the unified audit trail has been reported by Jeff Hunter and verified on at least two platforms, Solaris 10 and RedHat Enterprise Linux 6. While other ports of Oracle behave as expected (Windows and Oracle Enterprise Linux 7, to name two that I’ve tested) the problem platforms fail to return data from V$SESSION because the AUDSID values apparently (more...)

GraalVM – why a different VM?

If you read press around Java you’ll have come across references to GraalVM. So what is it and why would I use it?

There is an excellent podcast from Software Engineering Daily that digs into the subject and can be found here and here. But let draw out some of the reasons as to why GraalVM is interesting.

Whilst multiple languages on top of the JVM is nothing new, such as Scala , Kotlin, and (more...)

ORAchk (EXAchk) und der Collection Manager (Teil 1)

ORAchk & EXAchk sind wichtige Tools im täglichen Oracle DBA Geschäft. Allerdings habe diese Tools wenn man Sie einmalig oder mehrfach startet den großen Nachteil das man jeweils einzelne Reports erhält und diese nicht miteinander vergleichen kann, oder eine Historie erhält. Es bedeutet im Umkehrschluss man muss sich selbst eine „Ordnung“ überlegen und die Verwaltung übernehmen.

Genau an diesem Punkt kommt nun der „Collection Manager“ ins Spiel, der eine komplette APEX Anwendung ist und die (more...)

Eviction Notice


"Expectations is the place you must always go to before you get to where you're going. Of course,
some people never go beyond Expectations, but my job is to hurry them along whether they like it or not."
-- Norton Juster, The Phantom Tollbooth

Oracle has decided that Solaris needs to retire, giving those who are running Oracle on Solaris roughly two years to move to another operating system. A possible choice involves commodity (more...)

Could RedHat’s absolute commitment to OpenShift put them into difficult waters?

As a middleware (to use a fading term) or technical architect, I preferred not to get too involved in the detailed OS layer considerations when it can be helped (my Infrastructure Architect colleagues will always know more about NICs, port bonding, kernel versions etc etc than I ever will) and why I prefer to work with PaaS over IaaS.

But there is an undeniable trend where having a greater understanding of the OS is necessary, (more...)

API Developer Podcast

The authors of the API Platform book, got to record an Oracle Developer Podcast together in support of the book – the recording can be here at here or at here

As ever, thanks to Bob Rhubart for giving us this opportunity.

 

hostname in Oracle Linux 7.x ändern

Möchte man in Oracle Linux Version 7.x (ich nutze hier im Beispiel OL 7.5) den „hostname“  ändern, hat man drei Möglichkeiten:

NetworkManager text user interface tool


# nmtui

Menüpunkt auswählen Namen setzen abspeichern fertig

NetworkManager command line tool „nmcli“ 

 


# nmcli general hostname

Setzen des hotsname mit

# nmcli general hostname o2

 

Das „hostnamectl“ Kommando


# hostnamectl set-hostname o2 --static

Überprüfen kann man seine „Arbeit“ wie folgt


# hostnamectl status
Static hostname: o2

Oracle Podcasts – Beer & Pizza

We have been fortunate enough to participate an ArchDev podcast about meetups – https://blogs.oracle.com/developers/pizza%2c-beer%2c-and-dev-expertise-at-your-local-meet-up

The podcast talks about the differences between the meet-ups and events such as conferences, what we try to get out of a meetup and the effort put into arranging them.

Oracle DB Upgrade 12.1 auf 12.2

Ich bin gerade dabei einige Datenbanken von 12.1 -> 12.2 upzugraden. Dazu setzte ich den DBUA ein und bin sehr positiv überrascht. Viele Checks werden im Dialog abfragt und diese werden dann während des Upgrade Prozess umgesetzt. Der Upgrade läuft reibungslos durch auch wie in meinem Fall auf RAC Datenbanken.

Möchte man den Pre-Upgrade vorab durchführen und dies per Skript steuern, dann kann man auf Metalink dazu ein Skript herunterladen. Dieses Skript sammelt (more...)

Introducing SQLdb360: merging eDB360 and SQLd360, while rising the bar to community engagement

Today, we are very happy to release SQLdb360, a new tool that merges together eDB360 and SQLd360, under a single package.

Tools eDB360 and SQLd360 can still be used independently, but now there is only one package to download and keep updated. All the new features and updates to both tools are now in that one package.

The biggest change that comes with SQLdb360 is the kind invitation to everyone interested to contribute (more...)

Oracle Code – Capgemini Blog

I have a new blog post over on the Capgemini site – https://www.capgemini.com/2018/06/oracle-code-london/ talks about the way Oracle has changed its engagement towards developers and the Oracle Code London event that I presented at – first mentioned at Oracle Code London – Presentation & Periscope Interview

 

Oracle Code London – Periscope Interview

Whilst in London Wednesday to present Microservices in a Monolith World at the Oracle Code London,  I also participated in an interview streamed via Periscope.  The interview can be seen at https://www.pscp.tv/w/1jMKgqBrwYyJL
