Which is the software needed for an installation on a production server

Hi,
which is the software needed for an installation on a production server (windows 2008) of Forms/Reports 11g ?
I mean the old 10g stand alone forms and report service but un 11g release ..
Regards

For application deployments (production), you will need the following software. The same is true for a design-time environment.
1. Weblogic Server 10.3.2
2. Fusion Middleware 11.1.1.2
See my update in the following:
Re: Some FORMS quesion...
All products are contained within the Fusion Middleware (Forms, Reports, Portal, Discoverer) distribution. This includes Builders, Runtime components, HTTP Server, Web Cache, etc. During the installation process, you choose which you want to install.

Hi! I can't upgrade my iTunes 10.3.1.55 on my Windows XP 2002 SP3 to the latest version of iTunes. Got the message: "A problem has occured with the Windows Installer-package. A program needed for this installation could not be run." What to do?

Hi! I can't upgrade my iTunes 10.3.1.55 on my Windows XP 2002 SP3 to the latest version of iTunes. Got the message: "A problem has occured with the Windows Installer-package. A program needed for this installation could not be run." What to do?

Perhaps let's first try updating your Apple Software Update.
Launch Apple Software Update ("Start > All Programs > Apple Software Update"). Does it launch and offer you a newer version of Apple Software Update? If so, choose to install just that update to Apple Software Update. (Deselect any other software offered at the same time.)
If the ASU update goes through okay, try another iTunes install. Does it go through without the errors this time?

Is 1GB ram is enough for the installation of oracle developer suite 10g and database 11g??? And which one to install first developer suite or database????

Temporary wim-files for multicast transmissions still needed for WDS installation in Server 2012 R2?

Acording to
https://technet.microsoft.com/en-us/library/dn281955.aspx one of the new features for WDS in Server 2012 R2 for multicast is:
Improved multicast deployment by eliminating the need for making a local copy of the install.wim file. You can apply the install.wim file while it is being downloaded without significant impact to the application process.
However, this doesn't seem to be activated by default and I still get the following error when installing one or more machines using multicast:
"Windows Setup cannot locate a valid hard drive to store temporary installation files." However, once I remove Multicast from this install image, it installs without any problems at all.
I have also noticed that while multicasting, the installation will use the "Copying Windows files" phase, while downloading and copying the install.wim (or whatever name it is) locally on the hard drive first, so this will require lots of space.
So the question is, how do you enable this new feature that should be a part of WDS in Server 2012 R2???

Full version:
Following steps could help enable the feature:
1. Mount the boot image using dism.
e.g.
>dism /mount-wim /wimfile:c:\remoteinstall\boot\x64\images\boot.wim /index:2 /mountdir:c:\mount
2. Create a metadata file if no existing one. The metadata file should be in mountdir from the first step under mountdir\sources. And the file name should be: WdsClientMetadata.txt
3. Add entry to the metadata file: WDS.Client.Multicast.WIM.Streaming.Enabled=true
4. Save changes and unmount the boot image
e.g.
>dism /unmounts-wim /mountdir:c:\mount /commit
Sorry for the late reply, but I had to test this thoroughly since I didn't get it working right away. I tried both the regedit you first mentioned, and later also creating a textfile in the "/index:2 boot.wim", both without any success. I noticed
that creating the sources\WdsClientMetadata.txt with the data "WDS.Client.Multicast.WIM.Streaming.Enabled=true" gives me an error upon booting into WDS as follows (EUFI/IPv6-boot):
Same happens if I boot using IPv4 (an non-UEFI boot), except that there would be a plain IPv4-address instead in the error msg. Just for troubleshooting I tried writing WDS.Client.Multicast.WIM.Streaming.Enabled=false in the file instead, and WDS would throw
me the exact same error message. Once I delete the file sources\WdsClientMetadata.txt from the WDS/Boot image, the client boots ok, both for IPv4/IPv6. Disabling the firewall on the WDS didn't help, so something in the configuration is still missing? I'm getting
to a dead end here, and I suppose you're all out of advice on this one?
Thank you Shaon Shan for your great effort so far.

Need for an aditional enterprise oracle license in a cluster

Hello,
I would like to know about the oracle licensing (*enterprise 11g*) of the following structure:
# Cluster of an active-passive operating system with only one active server. The secondary node will take over the services only in case of failure of the primary.
# A secondary data center with one more node of the cluster and with data replication from the primary storage.
I know that for the cluster will require the licensing of only one server.
I wonder about the need for one more Oracle license for the second mentioned structure, where the passive server would only be used in case of failure of the cluster.
Thanks in advance!

You really, really, really want to have this conversation with Oracle Sales. Nothing anyone says here is in any way authoritative-- if there is ever an audit, you really don't want to explain that some guy on the internet with a playing card logo next to his name said it was OK. The answer may depend on the country you're in, your existing license agreements, your ability to negotiate with Oracle, your desire to buy other Oracle products, how much your sales rep likes you, the phase of the moon, how close your rep is to making their quota, your astrological symbol, and dozens of other factors. In other words, any answer would need to be taken with a few hundred grains of salt.
You'll want to refer to the Software Investment Guide, specifically the Backup/Failover/Standby/Remote Mirroring section. In general, you can have one failover node so long as you do not fail over for more than 10 calendar days per year and immediately go back to the primary once it is repaired. In general, you would need to fully license the failover data center. But, as I said, this is all subject to negotiation.

Instructions needed for importing a RoboHelp - Oracle Help file

Please provide instructions for importing a RoboHelp, Oracle Help file into an Oracle 8 software application.
Thank you,
Jennifer Byrne

The Oracle Help Guide documents how to program applications to support Oracle Help. Have you looked at it? The Guide is included with the downloads of Oracle Help for Java (OHJ) and Oracle Help for the Web (OHW) and you can also find it directly on OTN at http://otn.oracle.com/docs/tech/java/help/content.html.
But I'm not sure I understand your question completely. What do you mean by "import" the help into the application? I assume you are referring to programming the application to integrate the help into it; hence my suggestion to refer to the Oracle Help Guide, above. But perhaps I'm missing something. Also, what kind of application do you have? Is it a Java application?

Installation of oracle 10gR2 on Windows Vista Home Premium 64 bit OS

can we install oracle 10gR2 on Windows Vista Home Premium 64 bit OS ???
While doing sqlplus from command prompt,
it's giving error like
'SP2-1503 Unable to initialise Oracle Call interface'
'SP2-0152 Oracle may not be functioning Properly'
How to troubleshoot the above errors,
Has anybody tried it ???
Plz assist.

No Oracle product is certified against any Windows Home OS.
As Vista was released after Oracle 10gR2, 10gR2 is not certified against any edition of Vista.
You need to downgrade to XP, or install Linux.

How many F20-136 backup disks i need for clean OS installation?

Hi,
I wish to clean off my laptop and start again due to a various amount of unwanted programs I've installed.
I've found a Product Recovery disk (one) does anyone know if there is supposed to be any others and if so what they are called?
Hopefully its just the one, I seem to remember another disk of somekind but cannot find it.
Thanks
Mike

If you want to clean off your notebook install OS using delivered recovery DVD. On this way your Qosmio will have factory settings again. Before you do this install Qosmioplayer at first using delivered Qosmioplayer recovery CD.

-OyA specific ORACLE_HOME holds the binaries for a specific version of Oracle. You don't upgrade by simply installing a newer version of Oracle into the ORACLE_HOME of an older version. If you tried to do that you have probably irreversibly corrupted the original installation.

I'm new to mac. Is there a need for Clean my Mac?

I'm new to mac. Is there a need to have Clean my Mac on my computer?

How to maintain a Mac
Make two or more backups of all your files
One backup is not enough to be safe. A copy of a backup doesn't count as another backup; all backups must be made directly from the original data.
Keep at least one backup off site at all times in case of disaster. Backing up to a cloud-data service is one way to accomplish this, but don't rely exclusively on such backups.
In fact, don’t rely exclusively on any single backup method, such as Time Machine.
If you get an indication that a backup has failed, don't ignore it.
Keep your software up to date
In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.
Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Don't install such modifications unless they're absolutely necessary. Remove them when they are no longer needed. Before installing any Apple update, you must check that all system modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of difficulties with system updates.
Don't install crapware
...such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
It's not much of an exaggeration to say that the whole "utility" software industry for the Mac is a fraud on consumers. The most extreme examples are the "CleanMyMac," "TuneUpMyMac," and “MacKeeper” scams, but there are many others.
As a rule, you should avoid software that changes the way other software works. Plugins for Photoshop and similar programs are an obvious exception to this rule. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Only install software that is useful to you, not (as you imagine) to the computer. For example, a word processor is useful for writing. A video editor is useful for making movies. A game is useful for fun. But a "cache cleaner" isn't useful for anything. You didn't buy a computer so you could clean caches.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Do not rely on "utilities" such as "AppCleaner" and the like that purport to remove software.
Don't install bad, conflicting, or unnecessary fonts
Whenever you install new fonts, use the validation feature of the built-in Font Book application to make sure the fonts aren't defective and don't conflict with each other or with others that you already have. See the built-in help and this support article for instructions.
Deactivate or remove fonts that you don't really need to speed up application launching.
Avoid malware
"Malware" is malicious software that circulates on the Internet. This kind of attack on OS X was once so rare that it was hardly a concern, but it's now increasingly common and dangerous.
There is some built-in protection against malware, but you can’t rely on it—the attackers are always at least one day ahead of the defense. You can’t rely on third-party "anti-virus" products for protection either. What you can rely on is common-sense awareness—not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must come directly from the developer's website. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash. A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
Don't fill up your disk or SSD
A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a startup failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.
While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
If storage space is running low, use a tool such as OmniDiskSweeper to explore the volume and find out what's taking up the most space. Move seldom-used large files to secondary storage.
Relax, don’t do it
Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
To use a Mac effectively, you have to free yourself from the Windows mindset that every computer needs regular downtime for maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform.
A well-designed computing device is not something you should have to think about much. It should be an almost transparent medium through which you communicate, work, and play. If you want a machine that needs a lot of attention just to keep going, use a PC, or collect antique cars.
The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.
