WebLogic 12cR3 was released towards the end of last week, so this weekend I had an install-fest.
I also did some minor amendments to some existing articles.
From a newbie administrator perspective, like me, there is very little difference between WebLogic 12cR2 and 12cR3, so most of the time it is business as usual.
To coincide with this new release, Packt are doing a $10 promotion for WebLogic eBooks (WebLogic Partner Community EMEA).
Following on from my recent batch of “what I’m doing at the moment” style posts, I just thought I would mention some of the infrastructure I’ve been installing and configuring recently…
We are still part way through a migration from Oracle Application Server to WebLogic 11g. There are many applications to migrate and test, fortunately not by me, but they fit into two main categories.
Some of our high profile applications of each type are already running in production on WebLogic and the general feedback has been very positive. I guess most of this comes down to the hardware refresh.
There are still a few more apps to migrate, but everything is pretty close to the end of testing now, so hopefully it won’t be long before we can say a not-so-fond farewell to Oracle Application Server!
All of these WebLogic installations are running on top of Oracle Linux 6 inside VMware virtual machines. So far we’ve seen nothing untoward about this setup and I would have no reservations about recommending this approach to others.
If you have any questions/concerns about Oracle Linux, you might want to read my Oracle Linux : Frequently Asked Questions article. If you have any concerns about Oracle’s stance as far as VMware support goes, you might want to read this.
Following on from yesterday’s post about these WebLogic 12cR2 articles,
I’ve spent today creating ADF enabled domains and clustered domains on WebLogic 12cR2. That has spawned some new articles that are effectively updates of the old WebLogic 11g and 12cR1 articles.
With a bit of luck I will now be able to get through next week without looking like a complete idiot…
WebLogic 12cR2 is similar enough to 11g and 12cR1 to feel familiar, but there are tweeks here and there that make life interesting. The GUI screens have been prettied a little too.
As I keep warning, I’m a complete WebLogic newbie, so the content of these articles will evolve as I learn more and realise all the mistakes I’m making…
The new versions of the WebLogic 12cR2 and ADF could not have come at a worse time for me. My top priority is learning about the 12cR1 version of the database. Second, is getting to grips with Cloud Control 12cR3. Third on the list is getting up to speed with the changes in WebLogic 12cR2 and ADF. Unfortunately, my personal priorities don’t quite match my work priorities, so WebLogic 12cR2 has moved up the list for a while. As a result, I did some installations last night.
I’ll have to play with this for a few days to get my head round it as I may be doing a test installation at work early next week.
A word of warning. I am a self-confessed WebLogic newbie. If you ask me questions about it I will be redirecting you to people who actually know what they are talking about…
I’ve been grabbing a few minutes here and there over the last couple of work days trying to get something working with no joy. I this case it is a DAD entry in the “dads.conf” file on the OHS running as part of 11gR2 Forms & Reports Services on WebLogic 11g (10.3.6). I started to think that maybe this functionality is disabled on the installation or something like that, but couldn’t find any reason for that to be the case.
In a fit of desperation I came home tonight, fired up a DB and a F&R installation, defined a DAD and it worked first time. Aaaarrrggghhhh!!!!!
On the plus side, I know there is nothing fundamentally weird about the OHS installation that comes with 11gR2 F&R Services. On the down side, I still have no flippin’ clue why it is not working on the installation at work. Think I need to get in early tomorrow and focus on it for a little while. No doubt it will be something stupid I’ve missed while trying to do a bunch of different things at once.
File this one under:
Update: Fixed it. It was the bloody firewall. #DontForgetToCheckTheFirewall
I ran through a Forms & Reports Services installation on WebLogic 10.3.6 this morning, so I made some minor tweaks to my existing 10.3.5 articles on that subject.
The current spin of Forms & Reports Services has a prerequisite check for 10.3.5, so you just have to turn off the prerequisites check using this.
$ ./runInstaller -ignoreSysPrereqs
Apart from that it’s pretty much business as usual.
In an attempt to delay packing for my trip, I decided to give the server installation on Linux a go.
The installation was pretty straight forward. I will take a look at some of the further configuration stuff when I get back from my trip.
At least one of the apps at work will be moving to Forms 11gR2, so I thought I better do a run through of the desktop developer installation before someone asks me how it is done.
Our standard desktop environment is still Windows XP (32-bit), hence the archaic choice here.
The server environment will be Linux 64-bit, so when I get back from the next trip I will probably do a write up of that installation. The install steps will be pretty similar, but I like to have a no-brain-needed guide to follow when I do these things.
I knew Oracle had bought BEA, so I knew they had acquired the WebLogic stuff, but I can’t remember reading that they had practically scrapped their own Application Servers in favor of it. The last I read about it was this:
Yet a quick visit to the Oracle websites makes it look pretty clear that WebLogic is the platform of choice:
I’m sure quite a few people with a vested interest in the original Oracle middle tier will feel a bit annoyed by this…
So all these years I’ve been listening to Oracle tell me their App Servers are the best, then they scrap it overnight…
Have I been snoozing and missed something? Am I mistaken? Am I confused?
Probably all three…
Update: I’ve just done some more Googling and it looks like the writing has been on the cards for a while, so it looks like I’ve been snoozing and missed it…
I guess next I’ll find out Oracle have bought Teradata and the database is now called Oracle Teradata 12g…
