Enhance Vagrant provisioning: install java and database

In my previous blog posts (here and here), I wrote about how to create a base box and a create and start a virtual machine out of it. I started with provisioning, to have the vagrant user adapt the kernel settings, add a install user/owner and create a filesystem on an added disk.

Now let's make the provisioning a bit more interesting and install actual software in it.

Installing haveged from Oracle repositories

In my previous blog, I mentioned the installation of the utility Haveged that is used to increase your entropy on non-gui systems. Since you can download it from the Oracle yum repository, I figured that I could install it from yum too, instead of using rpm. This prevents me from having to download it myself, and ensures I have the one that is applicable to my version of Linux.

Too bad it isn't (more...)

Base box ready? Let’s create a box!

Last week I wrote about creating our own Vagrant base box, based on the new and fresh Oracle Linux 7 Update 5. As a reaction on my article I got noted that Oracle also keeps base boxes for their latest linuxes at http://yum.oracle.com/boxes. They're also a great start.

To begin, I created a project structure for all my vagrant projects:
As you can see, I have a vagrant main projects folder on my (more...)

Oracle Linux 7 Update 5 is out: time to create a new Vagrant Base Box

It's been busy, so unfortunately it's already been almost two weeks I wrote my introductory story on Vagrant. Today I happen to have an afternoon off, and I noticed that Oracle Linux 7 Update 5 is out. I based my first boxes on 7.4, so nice moment to start with creating a new Base Box.

De essentials on creating a Vagrant base box can be read here. But I'm going to guide you trough (more...)

The vagrant way of provisioning – an introduction

About 2003, I guess, I was introduced into VMWare by a colleague. I was hooked about right away.
Since then I made numerous VMs for as many purposes. I played around with several VMWare products, but since Oracle acquired Sun, I stuck with VirtualBox.

A few years ago the tool Vagrant was mentioned to me. But I did not get the advantage of it, since all I needed to do I could do using VirtualBox.


PaaSForum and the talk with the two ladies…

It's already been a week or three that I've been to the excellent PaaSForum '18 in Budapest.
Much is already said and written about it. About the talks and breakout sessions.
To see and hear about the state of art of the Oracle PaaS products: every year I'm having a good time with Oracle Friends around Europe and beyond.

It was nice to play around with API Management, Dynamic Processes, Oracle JET and ChatBots. And, ... (more...)

SQLDeveloper: User Defined Extensions and ForeignKey query revised

It was so fun: yesterday I wrote  a small article on creating a query on Foreign Keys refering a certain table. A post with content that I made up dozens of times in my Oracle carreer. And right away I got 2 good comments. One was on the blog itself.

And of course Anonymous is absolutely right. So I added 'U' as a constraint type option.

The other comment was from my much appreciated (more...)

Which tables have foreign keys refering to a particular table?

Ok, this time a quick not so exciting post. Actually, I find my self recreating a query again, that I created many times in my carreer. So, why not post it?

Last year, I published my Darwin Object Type Accelerator (Dotacc). It allows you to generate objects from a datamodel. What it also does is create collection types for tables that refer to the tabel you want to generate an object for. For some you (more...)

Set the minimum password length on your default authenticator in Weblogic

End of last year I wrote how to create a demo community of users in your Weblogic using wlst.
Using these scripts I wanted to do the same at my current customer: creating test users in the DefaultAuthenticator. However, I faced that the minimum password length was 8, while one of the user failed creation, because the password was the same as the user, and only 5 characters long.

So I need to change the (more...)

Weblogic 12c + SAML2: publish your metadata over an URL

This week I got to do a SAML2 implementation again for APEX against ADFS. Actually the same setup as last year. One pitfall I fell into with open eyes, was the Redirect URI on the 'Web SSO Partner Provider'. I entered /ords/f*, but it had to be with out the wild-card: /ords/f. But that aside.

At one step in the setup of a SAML2 configuration is that you have to publish the metadata, by (more...)

How to install the Notepad++ 64-bit plugin manager

I'm a Notepad++ fan for years. And as soon as a 64-bit version arose I adopted it.
But since a few months I have a new laptop, and I apparently didn't get the plugin manager with the latest new install.  And only now I took the opportunity to sort it out and write about it.

I found that the plugin manager is available since April 2017 on GitHub, version 1.49. I downloaded the (more...)

SoapUI: validate a date field in response with current date

Once in a while you need to validate a service that has dates in the response. Although SoapUI has xpath and xquery match assertions, validate against strings is quite difficult. How to do a date comparison against for instance the current date?

You can do it with a script assertion:
And the content of this can be:
def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
// Set Namespaces
def holder = groovyUtils.getXmlHolder(messageExchange.responseContent)

Run SQLcl from ANT

I think since last year ORacle released SQLcl which could be seen as the commandline variant of SQL Developer. But even better: a replacement of SQL Plus.

A few years ago I created what I called a InfraPatch framework, to do preparations on an infrastructure as a pre-requisite for the deployment of services and/or applications. It can run WLST scripts for creating datasouces, jms-queues, etc.  It also supported the running of database scripts, but (more...)

OSB 12c Customization in WLST, some new insights: use the right jar for the job!

Problem setting  and investigation

Years ago I created a Release & Deploy framework for Fusion Middleware, also supporting Oracle Service Bus. Recently revamped it to use 12c. It uses WLST to import the OSB service to the Service Bus, executing the config file.

There are lots of examples to do this, but I want to zoom in on the execution of the customization file.

The WLST function that does this, that I use is as (more...)

Create the SOA/BPM Demo User Community, with just WLST.

As said in my previous post (I've learned somewhere you should not post twice on the same day, but spread it out over time), I'm delivering a BPM 12c training. And based it on the BPM Quickstart. Although nice for UnitTests and development, the integrated weblogic lacks a  proficient set of users to test your task definitions.

Oracle has a demo community and a set of ANT and Servlet based scripts to povision your SOA (more...)

BPM Exception when deploying BPM project with Human tasks

This week I deliver a BPM 12c Workshop, that I based on the BPM QuickStart. When the students worked on the lab on Human Workflow, they hit an error deploying the Composite, where in the log you can find something like:

Caused By: oracle.fabric.common.FabricException: Error occurred during deployment of component: RequestHolidayTask to service engine: implementation.workflow, for composite: HolidayRequestProcess: ORABPEL-30257

exception.type: ERROR
exception.severity: 2

OSB: Disable Chunked Streaming Mode recommendation


These weeks I got involved in a document generation performance issue. This ran for several months, maybe years even. But it stayed quite unclear what the actual issue was.

Often we got complaints that document generation from the front-end application (based on Siebel) was taking very long. End users often hit the button several times, but with no luck. Asking further, it did not mean that there appeared a document in the content management (more...)

SOASuite 12c: keep running instances using ANT

At my current customer I implemented a poor man's devops solution for Release and Deploy. It was based on a framework created as bunch of Ant projects, that I created years ago. It was based on scripts from Edwin Biemond. See for instance here, here and here. I never wrote about my solution, because although I refactored them quite intensively, the basics were already described thoroughly by him.

What I did was that I (more...)

Enable WebService test client on SOA/BPM production mode environments

At my current assignment I need to trouble shoot the identity service because of a BPM->OID coupling. I use the support document 1327140.1 for it, that suggest to test http://<soa-server>:<port>/integration/services/IdentityService/identity

Doing so in a production mode soa or bpm environment, you'll soon find out that it uses the WebService test client via uri /ws_utc, and that this does not work. Resulting in http-404 Not found errors.

First I found a blog of Maarten of Amis (more...)

Implementing the KeyStore Service with Fusion MiddleWare 12c

For the passphrases, use the passphrases used earlier.Thinking about TLS (Transport Layer Security, the succesor of Secure Socket Layer, SSL) and WebLogic and Oracle HTTP Server, allways gave me Cold Water Fear. You have to create keystores with keys, wallets, certificate signing requests, import signed and trusted certificate chains. Not to mention the configuration of WebLogic and OHS.

Now, creating keystores with the Java Keytool turns out not that hard. And generating the Certificate (more...)
