Oc4j standalone running better than AS

Hi,
I have problems with Oracle Application Server 10g. Before, In the development phase, me and team always using standalone OC4J which was taken from OracleIDS 10g and everything running well. Now in production we decided to use oAS Forms Services, but oAS is ALWAYS down less than 3 minutes since reach the main page with this error :
FRM-92102: A network error has occured
The Forms Client has attempted reestablish its connection to the Server 1 time(s) without success. Please check the network connection and try again later
Details...
Java Exception:
java.io.IOException: Connection failure with 500
After we refresh the page, usually browser will show '500 Internal Server Error'. And after we refresh about 2 or 3 times, we can access the main page again. Both OC4J and oAS are running in Windows 2003 but in different machine.
I'm new in Application Server, I don't understand why standalone OC4J could be better than oAS. Please help me to find out and solve the problems.

Hi,
The FRM-92102 indicate to network problem.

Installed RT2500-Replug and now my Mac runs better than ever?!?!

I've been using a Netopia USB wireless Card to side-step my airport issues for about 2 months now. There is a glitch that causes the USB card not to be detected on start-up so someone recommended I download this http://mitglied.lycos.de/thomsmac/RT2500Replug.html but before I did the problem rectified itself for some reason and the card started being detected.
Today I unplugged the Wireless card and started up airport to see in the airport update fixed anything for me. It didn't so I plugged the USB wireless card back in but unfortunately the detection problem returned. I download and installed RT2500-Replug and was shocked. I have no idea why but my Mac is now running better that it ever has in the 3 months I've had it. Webpages are loading instantly, Google earth is silky smooth. Not only that but applications are launching faster! I've checked my states and for some reason my Macs RAM usage has been cut by one quarter.
Anyone have any idea what might have caused this? The difference is so noticeable its almost worrying. Might I have had some kind of conflict that the downloading RT2500-Replug might have solved?

You're going to have to give us a LOT more details than that!
Specifically which OS did you install? You say "latest version of Leopard", but that was 10.5. 10.6 is "Snow Leopard". Go to the Apple menu, click About This Mac. That tells you the exact OS version. Give us the processor speed that's there, too, and let us know the approximate (or exact, if you have it) age of your Mac.
How much RAM (memory) do you have installed? Again, it's under About This Mac.
How much hard drive space do you have available? Click on the "Macintosh HD" on your desktop, click cmd-i and look for "Capacity" and "Available".

How to clear cache on oc4j standalone?

I have the 9.0.3 oc4j standalone running under solaris and for the life of me cannot figure out how to clear the cache. I run a jsp script then delete the jsp script and it still runs. Even if I restart the oc4j standalone and the jsp is deleted it still runs!!
It is not a browser cache thing it must be the oc4j cache. Is there a way to clear this cache? This is a vanilla install of the oc4j standalone, no special webcache or anything. Thanks. -quinn

A JSP is typically compiled and run from the j2ee\home\application-deployments directory. Delete everything in there to remove the cache.

Does iTunes run better on a Mac than a PC?

I have a PC with Vista on it and I am experiencing a host of problems with iTunes. It's to the point where I'm considering buying a Mac mini. I know all you Mac die-hards will probably tell me that's the only way to go, but does iTunes REALLY run better on a Mac than a PC?
I'd really appreciate an honest opinion before I make the $ investment.

Almost never Jill.
Windows connects iPods as external hard drives. iTunes sees it as an iPod, but sometimes Windows doesn't. In order to disconnect, you have to use the Remove Hardware function in Windows. Apple stuff doesn't really work like that, though you do have to "Eject" drives. It's a little more straight-forward than Windows.
Software on any system can get funky and freeze or close unexpectedly. However, on a Mac, it tends to not happen as much. Again, the software and the system are made by the same people - so it just works together.
I would recommend heading in to an Apple Store if you can and checking out some of their free workshops about iPods and iTunes, talk to a Specialist or two on the sales floor about why they love their Macs, and then test one out. You can set up a Personal Shopping: http://www.apple.com/retail/personalshopping/
They'll have someone waiting for you (and it's often one of their best).
Also, sign up for One-To-One training at the store. You get up to an hour each week, up to 52 weeks and you'll be able to get self-paced, personalized learning out of it. Only $100 too, so it's a great deal. (and let them know that some guy on the Mac forums told you about it .. haha).
Hope some or all of that helps!

Is a dedicated graphics card better than an integrated graphics card for running Logic Pro?

I am trying to figure out if a dedicated graphics card is better than an integrated graphics card for using Logic Pro. I have heard opinions supporting both. From what I have been told a Mac mini with an integrated graphics card would work just fine. I have also heard that a modest dedicated graphics card could also benefit Logic Pro. Honestly, I have heard more people saying that the integrated graphics card on the Mac mini would do the job. But still, I have heard a couple people (even 2 senior Mac experts) state that a dedicated graphics card (iMac) is the way to go. Maybe a Mac mini with integrated graphics card will do the job, but an iMac would do the job better, I don't know, if anyone could help me I would greatly appreciate it. Thank you.

One thing is Logic Pro and another thing is Final Cut Pro. Logic Pro is a music production app, so it doesn't use the GPU heavily and you can use it with an integrated GPU without any problem. However, video editing apps like Final Cut Pro or iMovie will note the difference

What is OC4J StandAlone?

Hey Techies,,,,
OC4J standalone is a distribution of Oracle Application Server product that contains just the J2EE and Web Services components. OC4J standalone is much smaller than the full Oracle Application Server product and is downloaded as a single zip file. It is executed as a single Java process.
OC4J standalone is J2EE 1.3 compatible and is able to be used in both development and small scale production environments. OC4J standalone provides its own inbuilt HTTP/S listener to allow clients to execute Web applications that it has deployed. Application deployment and server configuration of OC4J standalone is performed by the manual editing of a simple set of XML files.
For large scale enterprise deployments, the Oracle Application Server product is likely to be more suitable with its comprehensive feature set including Oracle HTTP Server, process monitoring and management capabilities, and its configuration and management console.
IF THERE IS ANYTHING TO BE ADDED PLEASE ADD...
Thanks-San

It may be too obvious:
- OC4J standalone is a full J2EE container.
- It runs as a java application and you need to start it from the command line like java -jar oc4j.jar
- From 10.1.3 it includes a management console.
- As every J2EE container OC4J can run a number of J2EE applications which include EJBs, Servlets, JSPs, JSF and WebServices.
- Nearly the same J2EE container is included in Application Server (AS) but as has a number of additional features like opmn which takes care of starting OC4J containers when needed, eg when it crashes.
- With AS you manage more then one OC4J container while with Standalone you usually run one OC4J from the command line.

OC4J Standalone + iAS enterprise manager?

Hello everyone
We have recently been looking into OC4J standalone as a possible solution to our particular installation. We have an installation of iAS 10g2 which is configured so that each of our clients have their own environments; we mostly deal with legacy forms and reports. Each client has their own form listener, config files, report directories, etc. This is fine for our purposes.
The issue is with deploying applications in OC4Js. We could create an OC4J per client in iAS, but they would still all need the ias_admin password to deploy apps either through enterprise manager or JDeveloper. This is not desirable and is not going to happen.
With standalone OC4J we can have one per client, each with their different settings and passwords. Network ports are different for each client which is a bit troublesome but not a deal breaker. The big issue is with monitoring.
Is there any way to have the iAS 10g EM console include standalone OC4Js? Is there a way to do it from Grid Control?
Would appreciate any advice you may have.

There is recent a thread on here about how people have approached adding additional users over and above ias_admin for the purposes of managing EM. I haven't looked closely at the solutions yet, but I suspect that even by simply adding a new user as they are doing, the privileges the new user has will be the same as the ias_admin user -- in 10.1.2 (R2) and earlier it was a very coarse permission model.
And there's no support for managing OC4J standalone instances via EM or GC in R2.
What sort of applications are you deploying -- you mention forms and reports and in that regard you are restricted to R2. But if you are "deploying" custom Java applications, then using 10.1.3 (ie R3) may be an option -- in which case there are several things that may be of interest.
1. We've added support for a finer grained management model. You can create new users with a smaller set of administrative privileges -- all, deploy-apps, monitor. So you can create a cluster of servers, each with OC4J instances and users can login with their specified username and perform the tasks they have been assigned. It's not ideal since the permissions are relatively coarse (all, deploy apps, read/monitor) but its better than what was in 10.1.3.
2. If you wanted to pursue the standalone instance route, then with 10.1.3, each instance does actually embed EM, so it can be managed from a browser. With the pure standalone instances, you can't really collect them into a cluster -- each one is purely a standalone instance, but it now has its own EM console. However we have added an installation option to lay down what is essentially an OPMN managed standalone instance -- in which case you get the OPMN management layer around OC4J standalone, which in turn allows them to be collected into a cluster -- so you have a single point of management access for all the Oc4J instances. Again you could create an per instance user so that each user can only log into their own specific OC4J instance -- one thing to keep in mind that each instance does need the same global user provisioned to allow EM to operate correctly. But you can create additional users on an instance basis at will.
Again, all these things are in the 10.1.3 R3 release -- which if you are purely working with forms and reports won't help you. If you are deploying custom Java applications, then this is something you could investigate.

How to deploy an ADF RC application to any OC4J that running on Linux?

I developed an application with the latest Jdev 11gTP3. The team has a linux server that I want to install an OC4J and deploy my application.
I tried the following:
1. OC4J standalone 11g. Followed the installation instruction, with the command:
$ORACLE_HOME/bin/oc4j -start
I can initiate a server connection from Jdev, even passed test. But when deployment failed, I even tried to install ADF runtime library by following an Oracle official document. However, I can't get it work.
2. I tried to start the Jdev embedded OC4J with command:
java -jar oc4j.jar
I believe something has to be set before the application can work on this OC4J
Has anyone ever made it? Can you please share the steps of accomplishing it?
Many thanks in advance.

Thanks Frank for your reply
This can not be done with TP1 OC4J even with proper configuration and amendment?
How about WebSphere and Weblogic servers?
So at this stage, a TP3 ADF application could only run on JDev Embedded OC4J?

William

How can we say if Join better than using Sub Queries ??

Hi all,
I am trying to understand the rationale behind "Is _Inner Join_ better than using _Sub Query_ ?" for this scenario ...
I have these tables --
Table1 { *t1_Col_1* (PrimaryKey), t1_Col_2, t1_Col_3, t1_Col_4 }
-- Number of rows = ~4Million , t1_Col_3 has say 60% entries non-zero -----> (Condition 4)
Table2 { *t2_Col_1* (PK), t2_Col_2, t2_Col_3 }
-- Number of rows = ~150Million, t2_Col_2 maps to t1_Col_1 -----> (Condition 1). This means for every distinct value of t1_Col_1 (its PK) we'll have multiple rows in Table2.
Table3 { *t3_Col_1* (PK), t3_Col_2, t3_Col_3 }
-- Number of rows = ~50K, t3_Col_1 maps to t1_Col_2 -----> (Condition 2)
Table4 { *t4_Col_1* (PK), t4_Col_2, t4_Col_3 }
-- Number of rows = ~1K, t4_Col_2 maps to t3_Col_2 -----> (Condition 3)
Now here are the 2 queries: -
Query using direct join --
SELECT t1_Col_1, t2_Col_1, t3_Col_1, t4_Col_2
FROM Table1, Table2, Table3, Table4
WHERE t1_Col_1=t2_Col_2 -- Condition 1
AND t1_Col_2=t3_Col_1 -- Condition 2
AND t3_Col_2=t4_Col_1 -- Condition 3
AND t1_Col_3 != 0
Query using SubQuery --
SELECT t1_Col_1, t2_Col_1, t3_Col_1, t4_Col_2
FROM Table2,
(SELECT t1_Col_1, t3_Col_1, t4_Col_2
FROM Table1,Table3, Table4
WHERE
AND t1_Col_2=t3_Col_1 -- Condition 2
AND t3_Col_2=t4_Col_1 -- Condition 3
AND t1_Col_3!= 0
WHERE t1_Col_1=t2_Col_2 -- Condition 1
Now the golden question is - How can I document with evidence that Type-1 is better than Type-2 or the other way ? I think the 3 things in comparison are: -
- Number of rows accessed (Type-1 better ?)
- Memory/Bytes used (Again Type-1 better ?)
- Cost ( ?? )
(PS - testing on both MySQL, Oracle10g)
Thanks,
A

So, is it right to conclude that Optimizer uses the optimal path and then processes the query resulting in nearly the same query execution time ?If the optimizer transforms two queries so that they end up the same, then they will run in the same time. Of course, sometimes it cannot do so because of the the way the data is defined (nulls are often a factor; constraints can help it) or the way the query is written, and sometimes it misses a possible optimization due to inaccurate statistics or other information not available to it, or limitations of the optimizer itself.
Is this the right place to ask for MySQL optimization ?Probably not.

"A script is already running" while attempting to run more than one item

We upgrade recently to ODT 11.2.0.3.20. Since then, attempting to run more than one item from the Solution Explorer (by selecting the items, right-clicking, and selecting "Run") results in a popup error of "Oracle Developer Tools. A script is already running". If many items are selected it results in many error messages and only a random few of the items are actually executed on the server. Also, choosing "Run On" now results in it prompting for the target database for each item selected (rather than once for all items selected like it used to). This all used to work fine in the earlier release we were using. Has anyone else run into this? Any fixes? We used to use multi-select and "Run" or "Run On" to deploy multiple items at once, but this no longer works -- doing one at a time works, but if you have hundreds of items to run, this quickly becomes unusable.
Thanks for any insight.

I don't believe that the intention was for you to be able to run a bunch of scripts one after the other. Often there are dependencies between scripts anyway and so you you have to order them. Because we're generally deploying a large set of stored procedures (and not just one-time scripts) the order doesn't really matter -- even if a stored procedure gets created before one it depends on, once all the SPs are on the server, the ones that are "invalid" will compile correctly once you execute them.
I think a lot of people are creating master scripts that references child scripts using the "@" sql plus syntax.... have you tried that?
I'll give that a try as a work around. Only issue I have with that solution is every time we add or remove something from the solution, we also have to update the script.
We are doing a lot of enhancements to our script generation in the coming year. Keep an eye out for a beta to test.
Like I said, this used to work fine in the older versions of ODT. It seems like the new version is attempting to execute multiple items at once on the same connection simultaneously, thus resulting in the "A script is already running" error. The old version used to be smart enough to execute them one at a time -- so something changed in a more recent version to completely break "Run" and "Run On" when you have more than one item highlighted (even just highlighting 2 items and choosing "Run" runs the first item, but then gives the error for the second item).

Using the the multiple profiles and running more than one instance of Fire fox at atim

I use F/F in a gaming situation I needed to be able to run more than one session at a time and read about a feature called multiple profiles. Then I read iin another forum that I could have multiple instances with the following bat file :
@echo off
set MOZ_NO_REMOTE=1
start "" "C:\Documents and Settings\Hilton Wiggins\My Documents\Fire Fox non Beta\firefox.exe" -p-no-remote
set MOZ_NO_REMOTE=0
I also have the Beta 4.06 on my machine and even though the batch file directs it to wither the Beat or the Non Beta they both seem to track the profiles and can be used in either version.
However It's not working as I described running two browsers with grease monkey it will start to mis handle data and they both lock up

There is no need to set MOZ_NO_REMOTE, remove that part of the bat file. Change the start line to:
start "" "C:\Documents and Settings\Hilton Wiggins\My Documents\Fire Fox non Beta\firefox.exe" -no-remote -p "profile name"

The error was in the execution of OC4J embebbed. OC4J uses its own libraries for web services and xml.
You can deploy an application with JAX-WS 2.0 if you add this java option:
-Xbootclasspath/p:<dir_libs>\xml-apis.jar;<dir_libs>\xercesImpl.jar;<dir_libs>\xalan.jar;<dir_libs>\saaj.api.jar
And the jars of JAX-WS are added as libraries to the application.
With this solution you solve the problem: OC4J uses this libraries, not their owns, include the xml libraries.

Why Annyconecct is better than vpn client ?

why anyconnect is better than cisco vpn client ?
what is its advangatges ?
i think that both are remoteaccess vpn .
why its better ?

The other thing is that, Cisco does not support traditional VPN on Windows 8.X. I have run in to lots of issues trying to install Cisco VPN client on Windows 8.x clients.. it sometimes work and sometimes it needs registry hacks etc.. really painful setup for the network engineer. So Anyconnect is preffered.
Also, since SSL uses port 443/SSL by default, it does not need any ALG (Application Layer Gateway) functionality in remote end user's routers to operate, and will simply work with normal PAT which is always on.. with traditional IPSec VPN, since it uses ESP, you need to have AGL turned on on the user's GW router (this is normally called IPSec VPN pass through mode) and this sometimes doesn't work the way you want specially on the older residential routers. When this happens you really don't have any other option for those users.. and your only response would be "Sorry your router does not support this kind of VPN or your router does something strange with the VPN so Please upgrade your router" which is something the normal residential user don't want to hear.. and something you want to tell them..
So SSL VPN is the way to go..
please rate helpful posts :)

My palm calendar wont open after Lion download. Palm is so much better than ical, is it not going to work w/ Lion?

Palm calendar won't open now that I've downloaded Lion. Palm is so much better than ical. Is there a fix?

I miss Palm Desktop for Mac. The integration of contacts, to-dos, notes, appointments, etc. was great. I stopped using it about a year ago when I finally sold my Palm Tungsten T and purchased and iPhone 4. iCal etc. work fine for me, but they're not as good as Palm Desktop was.
I also miss Graffiti 1 handwriting recognition. I could write with it as fast and flawlessly as I can write longhand on paper, and nearly as fast as I can type. It was the best for meetings and interviews, since I could write without having to look at the screen. iOS has nothing that comes close; I've gotten used to the onscreen keyboard but it's slower, I make far more mistakes, and I have to keep my eye on the screen while typing.
As others have pointed out, Palm Desktop was written for PPC processors. Lion does not include and cannot run Rosetta, which is the emulation environment which allowed Intel processors to run PPC code. So Palm Desktop will not run on a Mac running Lion.
I was syncing to my Palm Tungsten T under Snow Leopard (and using Palm Desktop) with no troubles at all. There are third-party sync options available, but they're all kludgy and unreliable compared to Palm's own syncing. Again, though, the Palm software for syncing was written for PPC processors and so won't run on any Mac booting into Lion.
