Today I wanted to pass an old disk in a usb-case to my son. It was from an old Windows Laptop and even though I'm administrator, I wasn't able to read the documents in an other user's folder.
So I thought, let's do it from an Oracle Linux 7 VM, as root. But it turns out that Oracle linux did not support NTFS by default.
But with the trick in this link
I managed to (more...)
At one of my customers we have quite an impressive domain configuration. It's a FMW domain with SOA, OSB, BAM, WSM, MFT in clusters of 4 nodes. The thing is that when having started all the servers, the console becomes slooooooowwwww. Not to speak of FMW Control (em).
One suggestion is to set the 'Invocation Timeout Seconds' under MyDomain->Configuration->General->Advanced
to a value like 2. And 'Management Operation Timeout' under Preferences->Shared Preferences
to a value like (more...)
I have encountered several times in WebLogic 12c that when the ConnectionPool of a DataSource in WebLogic could not be initialized because due to a connection error or invalid username or password, the server could not be started.
I can't remember having encounterd this problem in 11g, and this week I struggled with it with one of my customers. The perception of the DBA there was that in 11g the server did start up, but (more...)
So let's start the day with a blog. In the past few months I created scripts to install FMW products and build a WebLogic domain for it. For most of my findings I did a blog already:
Last week I wrote a blog about how to create WebLogic users for ServiceBus 12c
. However, I did not now how to assign a particular Application Specific Role to the weblogic user, for particular ServiceBus privileges. I did find out what particular Roles there were (see the blog). But how to assign them I found out just today.
So here it is:
def grantOSBAppRoleToWlsGroup(osbAppRole, wlsGroup):
# Grant OSB AppRole
# http://docs.oracle. (more...)
In most SOASuite and Oracle ServiceBus projects the Database Adapter is used. And often it is used to invoke PL/Sql functions and procedures. Actually, it's my favorite interaction method with the database, since the re-entrancy of the database adapter wizard is best there. To do a re-entrant update of a select or DML operation when for instance a column is added, is simply put often quite problematic.
But the thing is with Pl/Sql that when (more...)
At one of my customers there was the question of creating users that needed to log on to EM (Fusion MiddleWare Control) and Service bus console to be able to deploy SB en WLS Artefacts (queues, datasources etc.) on the Dev and Test environment. And to be able to do some monitoring on Acceptance. Further more they still used weblogic as the only, shared, administrator user. For the latter Oracle recommends to create at (more...)
Two weeks ago, I wrote about how to set the log level voor SB Pipelines (12c)
to be able to see the logging of the Log activity in the WebLogic Server logs.
Today I encountered that for a developer at my customer the complete oracle.osb.logging.pipeline
logger was missing in the log-configuration. So setting the level from EM (Fusion Middleware Control) following the article above is a little hard.
I could not find (more...)
If you're a regular reader of this blog, you've noticed that I've been busy with creating soasuite/osb installations with weblogic domains in a scripted way.
I also optimized my start and stop scripts, that I'll post soon. All this work keeps me from writing on my BPEL book, so for those who are interested in my next episode, I hope you're patient.
But to get to that, it would be nice to have a running (more...)
At one of my customers we create Service Bus Weblogic Domains using a script, driven by a property file. But in one of the environments we encountered that the AdminServer was accidently called 'Adminserver', with a lower-case 's'. Now this is a very minor issue, but the administrator would like to have it fixed, since it is an anomaly regarding with other environments.
This week I got to implement my start-stop scripts (which I will (more...)
As a developer you probably 'log-a-lot' in OSB. (Funny term, perfectly to mock people that have the tendency to excessively add log activities/statements to their code. And hey, if you're being mocked like this: I'm happy to join you, let's make it a 'Geuzennaam').
So as a log-a-lot, I was questioned by a OSB developer this week on a OSB11g->SB12c upgrade that I support, that his logs weren't visible in the server-logs in de 12cR2 (more...)
Earlier you could have enjoyed my article on the automatic generation of a SOA/OSB domain
. Earlier this week I encountered some issues with a domain created at a customer this way
I got the change to dive into that this week and luckily not only I learned a lot again, but I found the problem as well. I adapted my scripts. I won't repost them completely, I've created a github account, and try to place (more...)
Since my previous long running assignment, I'm involved in a few OSB 11g to 12c upgrade trajects, where I have been working on automatic installs. Hence, my articles about automatic installs, patching and domain configuration
When I create a new domain, 12cR2 (12.2.1), using my scripts, I'm not able to use the nodemanager of the domain to start the servers. Actually, I can't connect to it. I get it running alright, but connecting (more...)
Years ago, in my Oracle years I wrote an article on Oracle (Object) Types, and how those make Pl/Sql so much more powerfull. It was in Dutch, since I wrote it for our monthly internal consulting magazine called 'Snapshot'. Since it was in Dutch and I regularly refer to it on our blog or in questions on forums, I wanted to rewrite it for years. So let's go. Oracle Types are introduced in the Oracle (more...)
In ServiceBus 12c you get a 'composite'-alike service overview for your project. It shows you how the proxy services (like Exposed Services in SOASuite) via pipelines are 'wired'to business services (like Referenced Services). This is nice!
If you upgrade a project from 11g or 12cR1 (12.1.3) to 12cR2 (12.2.1) this fails. Initially you might see a (correct) diagram, but after restarting JDeveloper this is empty. You'll get a Class cast exception:
Earlier I wrote how to automatically install the SOA/BPM QuickStarts
. Actually, I'm quite busy with doing automatic/scripted installs for SOA/BPM Suite and OSB, as you might have read.
At my current customer we encountered that in the last months there are many one-off-patches released on support.oracle.com
. We selected a pretty large bunch of patches and apply them one by one is a tedious job. But the thing is with these automatic installs that (more...)
Recently I blogged about the automatic install of SOASuite and ServiceBus 12.2.1
. It catered for the installation of the binaries and the creation of a repository.
What it does not handles is the creation of a domain. The last few weeks I worked on a script to do that. It's based on a wlst script for 12.1.3 by Edwin Biemond
. This one was quite educational for me. But as denoted: it (more...)
In the answer on a question on community.oracle.com, I found the following great tip: http://www.soatutor.com/2014/09/clear-mds-cache.html
In 12cR2 this looks like:
1. Start System MBean Browser; In Domain, pull down the Weblogic Domain menu and choose 'System MBean Browser':
2. Browse for the Application Defined Beans:
3. Expand it and navigate to oracle.mds.lcm, choose server (AdminServer or SOAServer1)
4. Navigate to the node Application em (AdminServer) or soa-infra (SOAServer) (more...)
Lately I worked on a set of scripts to automatically install Weblogic Infrastructure, SOA/BPM Suite, Service Bus, etc. Since I implemented a reworked set yesterday at another customer it might be nice to describe them here.
The scripts help in installing the software and creating the Repository. I started to create a script for creating the domain, but haven't it working yet. A good starting poing would be this blog of Edwin Biemond for the (more...)
And did you like it? Hardly possible to miss I think. It kept me nicely busy for a few hours. Got some great examples, and this one is purely based on css and unnumbered lists in combination with anchors. Unfortunately the menu worked with non-classed <ul>, <li> and <a> tags. So embedding the css, caused my other elements to be redefined. (It even redefined the padding of all
But with some trial and error (more...)
