What is the potential security risk to give 'any analysis' to a role or a user of 11.2.0.3 base data?
This is a HUGE security risk.
Any person who uses the ANALYZE statement may accidentally or INTENTIONALLY, destroy the overall system performance.
Just look at what the ANALYZE statement can do:
https://docs.Oracle.com/CD/E11882_01/server.112/e41084/statements_4005.htm
Goal
Use the
ANALYZE
instruction to collect statistics, for example, to:
- Collect or delete statistics on an index or index partition, table or table partition, table held in index, cluster, or scalar object attribute.
The ANALYZE statement has been deprecated for statistics for the DBMS_STATS package.
But what happens if the real and accurate data use by your important questions have been removed or replaced with nonsense, invalid statistical totall?
You could bring your system to its knees INSTANTLY. The system could start making full of HUGE tables table scans instead of using an appropriate index.
TERRIBLE, TERRIBLE thing to do to grant this privilege unless absolutely necessary.

What is the Windows Security Center and is compatible with Avast antivirus Protection?
I installed a paid for version of Avast on my Windows XP computer. (I won't be upgrading to a more modern version of Windows.)
I also called Windows Security Center.
Is the Windows Security Center virus protection, or is it simply a place to control and discover whatever you have antivirus protection?
If it is a virus protection, it would hurt Avast and if so can I uninstall it?
If I removed Avast and didn't have Windows Security Center, I should any type of protection against viruses on my computer?
The only type of protection against viruses in addition to Avast, I am sure that I have on my computer is Windows Firewall. I turned that off and am now strictly protected by the firewall of Avast. Windows Security Center notifies me of cannot have two firewalls upwards at the same time.
If Windows Security Center antivirus protection it would do no harm to leave it on if the firewall is disabled and Avast is installed? Part of Windows Firewall Security Center Windows or another program?
Guesses are welcome. Thank you.
Hey there Clinton!
I've identified two questions here, your normal text questions and my answers in bold:
Is the Windows Security Center virus protection, or is it simply a place to control and discover whatever you have antivirus protection?
Windows Security Center is not a virus protection it's just simply a place to control and view the status of the installation of malware * protection software, but also the firewall on your computer.
Part of Windows Firewall Security Center Windows or another program?
Windows Firewall is a separate component.
Does Avast! Damaged, if I have another antivirus running program?
It is not clear what might happen, but software may conflict with each other and may not work as expected.
I hope that I have answered all your questions!
Sincerely,
-Alex* - Malware is the generic term for all malicious software in the calculation. The virus is actually a sub-category.

I'm not a professional and I am very new to adobe, but I'm working on group projects with other people and they asked that instead of export of audio and video files, hearing, or first, I actually just give them the project so they ca works on it, as well in case any changes need to be made.
Is it possible to share the concrete projects (not exports) WITH all the video and audio still in place with other people on other computers? If Yes, what is the best way to do this?
Thank you very much in advance, even if it's completely impossible.

This page has a potential unspecified security risk.
Hello
I watched this program on several sites and I saw the same solutions related, but none have worked for me, so I thought I'd go to the source.
Here's the question: I have a link in my taskbar in my My Documents folder, that, when I try to open it, I'm presented with this message:
This page has a potential unspecified security risk. Do you want to continue?
If I select Yes, there is no problem, and my My Documents folder opens. However, it's a nuisance, and I would like to stop this message from popping up every time.
Regarding my setup:
I am running XP SP2 (w / no intention to install SP3) on my desktop system I try to access my My Documents folder. I also have a file server, that I call the USC, under Ubuntu 8.04.4 LTS and sheltering a RAID 5 array and using Samba. I have this table mapped to my desktop as Y: System. The path to my My Documents folder is Y:\backups\my_docs. Before a few days ago, I never had no problem with this.
I am trying to add another array of RAID 5 to this file server, and I had some problems w / Samba. At one point, I removed this mapping, while I was testing various configurations. When I tried to re - map, I had connection problems. Apparently, some of the changes I made now forced me to connect to that share without providing credentials. So, just to be clear, before that, I got this mapped drive, then set it to reconnect to the opening, and there is no problem. If, for some reason, I never had to re - map, all I had to do was provide my credentials and it matched with or without a problem. Now, when I map, it requires no credentials, and it is simply the share.
However, after everything that's happened, when I now, select the shortcut to my My Documents folder link, I get this notification. I tried to delete and recreate the shortened link, but that did not help. As I already mentioned, I had read several other sites, and I tried a few solutions, most of them of adding this share to the list of sites in my Local Intranet options w / in IE8. I even tried under Trusted Sites. Nothing has solved the problem. It was also recommended that I have untick automatically detect it Intranet network, which I did, but to no avail.
Currently, my installation of IE8 is as follows:
Local intranet is set to medium-low security (I tried low, but it does not, either). Is checked automatically detect Intranet network, and file://usc is added to the zone.
Trusted sites is set to medium security, and I have no entries in its area.
W this question, any help would be greatly appreciated. Thank you very much.

What is the problem with the updates?
Vista HP, SP2, 32-bit
I have 10 updates ready to install, but when I invite them to do Windows update crashes just for hours. It becomes quite annoying because I can't turn off my PC: it starts to 'install' and just stays there.
I tried restoring the system twice and attach it to the tool. It did not work.
This is my third post on the topic, given that the other two didn't get any answer. There are several other users with similar problems, but they have no answers as well.
Any feed back is in order, because we do not ask on some free program, that we have found on the NET, but a bone, we paid for .
If the mods in this forum do not know the answer to the less direct us to where we can find one.Jose.
During the latest two updates for Outlook, I was not having not updated again and again even after it recharges, cleanings, scans, etc. I looked on Google KB numbers and hit the Microsoft Website to download the fix. That did the trick, both took and when I then rechecked the windows update app magic "No important updates available" appeared - yay!
Recommend that you download the .exe of Microsoft patches and ' Run as Administrator year ' to get a patch of failing to take.
Good luck.
