Let's say you have a virtual machine with two network adapters, both set on 'HostOnly'.
I used to do that and set the first one of those to a fixed IP address, say 10.0.0.1. To this one I coupled the hostname, for instance darlin-vce-db, using the /etc/hosts file. That way I had a fixed, always existing network address for the database.
Together with the database, you install WebLogic, for instance to serve (more...)
To day I had some problems with deploying my composite to the server of my current customer. Apparently the Server had some problems with datasources. But since there are many I did not feel much for checking them one by one with the console. Using Google I got the following examples
A few months ago I figured out how to create specific users with restricted access to Service Bus components. I blogged about it in part 2 of creating WebLogic users for ServiceBus 12c
. But the series lacks an explanation on restricted user access on SOASuite.
Today in a question about Roles on Oracle Community Forums
, the reference to this elaborate blog entry was given: Restricted View
, by Antony Reynolds.
I think that blog (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...)
For a project, we are migrating Forms to ADF.
There is also a number of reports which are not to be migrated yet.
Therefore, we need to keep the users in the database.
As we do not want to maintain two user stores, we thought it to be a good idea to create an authenticator in WebLogic to authenticate to the database.
There are loads of blog posts / support notes on how to configure (more...)
Logging is a very useful feature of WebLogic.
Unfortunately the log levels, which are set after a clean install of WebLogic or some of the Fusion Middleware product creates a lot of noise and therefore it costs I/O performance.
Additional after analyzing an issue with logging often resetting the log level is forgotten.
Here you get a script to reset the log levels at regular intervals or after a trace session.
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...)
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...)
Creating FTP connection factories using the Weblogic console can take a lot of time, mainly because it are multiple screens you have to click through every time. But creating these FTP connection factories can be done a lot easier and faster when using a WLST script.
The following script can be used as a base for your script to generate your FTP connection factories. I have used this script on a Weblogic 12c environment.
# Script (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...)
I’m spending some time building out an Oracle WebLogic/Veridata system at home. This is mostly for testing and general understanding purposes. One of the things I’ve noticed with the WebLogic server requires the username and password before the WebLogic server will start. After providing the name and password, the terminal window has to stay open because, closing it will kill the WebLogic server that is running. This leads to two interesting question and simple resolutions.
