Problem in protection mode dataguard
Hi,
i want to store standby redo log archived file in separate folder, so that i specified
log_archive_dest_1='LOCATION=D:\oracle\product\10. 2.0\flash_recovery_area\stby VALID_FOR=ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=stby
standby_archive_dest=D:\oracle\product\10. 2.0\flash_recovery_area\stby\arcst
If both parameters are specified, the STANDBY_ARCHIVE_DEST initialization
parameter overrides the directory location specified with the LOG_ARCHIVE_DEST_n
parameter.
but in my system it store all archive files in LOG_ARCHIVE_DEST_1..
normally if you change primary database protection mode into maximize availability ,then it should automatically change standby database into that mode ...
primary database(live).
should i change this mode in both primary and standby database????
SQL> select protection_mode,protection_level from v$database;

selva,
log_archive_dest_1='LOCATION=D:\oracle\product\10. 2.0\flash_recovery_area\stby VALID_FOR=ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=stby
standby_archive_dest=D:\oracle\product\10. 2.0\flash_recovery_area\stby\arcst is correct and will not override your primary entry... the log_archive_dest_1 is where your primary logs are generated and standby_archive_dest is where your logs will come when current server acts as secondary.
your actual question is regarding protection modes....? is that correct
after you chnage the protection mode did you stop managed recovery and bounce the database on stby,,,
try this and let me know

Printing problem in Protected Mode - Adobe Reader X
Hello,
I have a PDF printer driver and Adobe Reader X. If I right click on my PDF file and select the print option, the generated PDF file will become ”gibberish”. I have checked the settings of the Adobe Reader X and I have found the “protected” mode option on by default. If I disable this option, the printed PDF file is printed correctly.
I have continued testing and have noticed when protected mode was enabled the adobe temporary fonts have not been generated into the temporary folder but when I disabled protected mode the adobe temporary fonts have been created.
How can I use the Adobe X in protected mode to print to a PDF printer driver so the fonts are generated correctly?
ThanksHi, thanks for your support.
I am using Black Ice PDF printer driver
Issue is not happening for all PDF files. It seems only which contain temporary fonts and when protected mode is turned on, and when right clicking on the document and selecting the "Print" option.
On physical printer I could print ok.
How can I share the file for you?
Thanks again. -
Adobe Reader XI protected mode problem
I downloaded Reader XI and went to open a pdf that previously worked with Reader. But Adobe Reader XI won't open (says problem with "protected mode"). I can't open any pdf's either on my computer or on the internet at trusted sights. Troubleshooting takes me to a page on fixes for Reader X. Not helpful! Any ideas? (I uninstalled and reinstalled and still won't work.)
CoUnyot,
Thanks for your post ...
Please Disable protected Mode .. Please find the below steps ":
Disable Protected Mode by going to Edit > Preferences > General and deselecting Enable Protected Mode at startup.
Restart Reader.

9i Dataguard Problem in MAXIMUM PROTECTION mode
Dear All
Hi
I have 9i Rel 2 (9.2.07) dataguard environment on Linux Redhat Advanced Server 3
The Pretenction mode is Maximum Protection
One day I noticed that my dataguard Database is about 100 log files before than the Primary:
On priamry the current log sequence# was 7804
But in standby the last log that was transfered and applied was 7716
In primary I executed the following select:
SQL> Select protection_mode , protection_level from v$database;
the result was:
protection_mode=MAXIMUM PROTECTION
protection_level=SYNCHRONIZING
What I want to know is:
Why the primary database did not become shutdown when it is in MAXIMUM PROTECTION mode and why it has continued working when the log files could not transfer to standby database ????
Thank you in advance for your replyAnybody any idea ??????

Adobe Reader cannot open in Protected Mode due to a problem with your system configuration.
From Adobe website: "Note that this list is not regularly maintained as Protected Mode now runs transparently in the background and it is unlikely that users will experience issues."
This explanation on the Adobe website does not explain what the problem is with the "system configuration". What is the system configuration problem?Hi Steve,
As mentioned on the troubleshooting page as well normally application like antiviruses, encryption and system maintenance tools causes this kind of problem. These software software intercepts some system calls for the Reader sandbox. Could you please check if you have any of these kind of software installed? Could you please answer following question then I would be in better position to help you?
1. Version of Reader being used
2. OS
3. What happens if you choose launch unprotected? Do you see a failure or Reader launches?
Thanks -
Dataguard 'max protection' mode failed
Testing Dataguard in MAX PROTECTION mode on Oracle 10.2.0.4 on Solaris x86_64.
Test 1: Primary remained up allowing transactions to continue inspite of the fact that the server running the standby database was not reachable. Waited for over 10 minutes and then cancelled the test. All that happened was the protection_level changed to resynchronization. I could not believe my eyes. Is this possible?
Test 2: The primary shutdown automatically but after about 6 minutes of the standby database was shut abort. So what about all those transactions that took place during those 6 minutes? Those would be lost - isnt it?
I just cant believe this. Where am I going wrong? I confirmed that LAD_2 was set to lgwr sync affirm. And that protection mode was set to 'maximum protection'.
Somebody, pls enlighten me?
Thanks
Edited by: user12022918 on 27-May-2013 08:42If you have several physical standby database for the same primary database then this could be expected behaviour otherwise this looks like a bug that you should report to Oracle Support who will very likely ask you to upgrade at least to 10.2.0.5 patchset or 11.2.0.3.

When I click a pdf file to open I now (this is new) get the message "Do I want to allow the following program to make changes to this computer?" Click yes and get a window saying "Adobe Reader cannot open in Protected Mode due a problem with your system configuration. Would you like to open Adobe Reader with protected Mode disabled?"
Why do I suddenly have to go through all these steps open a pdf document?
How do I go back to just double clicking and, voila, it's open.Please don't post the same question multiple times!

Choosing protection mode for Active dataguard
Hi Gurus,
I'm confused with Active dataguard configuration-What mode do i need to configure physical standby to make use of actice dataguard.I know i can even use maximum performance with standby redolog for real time query.But what is the minimum protection mode to run active dataguard.
How can i setup a delay of 1 hour for active dataguard in 11gr2?
ThanksYou said:
>
By default Dataguard is in Maximum performance mode..we can set delay of 1 hour by setting the
log_archive_dest_2="service=to_standby lgwr async affirm reopen=60"
or
log_archive_dest_2="service=to_standby lgwr async delay=60"
>
I am sorry, but your first log_archive_dest_2 value is not correct:
The combination of ASYNC & AFFIRM is not supported and not sensible; REOPEN=60 will not delay the Redo Apply
See here for a proper explanation of log_archive_dest_n:

When the phone is in protection mode lock and comes a missed call .. and when you scroll to the number, the phone call is in safety mode ... I want a solution to this problem .. Thanks
I've tried to respond to your post, but I cannot understand what you are asking. Also not a good idea to post your personal information on a public forum. I've asked the moderator to edit the post.

Reader 10.0.1 protected mode problems
I just upgraded from 10.0.0 to 10.0.1. (Windows 7 x64, SEP 11 RU6mp2 for antivirus) While reader 10.0.0 worked just fine, I cannot get 10.0.1 to open without disabling protected mode. I have seen the same problem on another machine running Win2003 server r2 x64.
This appears to be caused by folder redirection/roaming profiles. 10.0.1
works if I log on locally. Am I more secure using 10.0.0 with p
rotected mode or 10.0.1 without protected mode? -
Dataguard: RESYNCHRONIZATION state for MAXIMUM PROTECTION mode
Dear All
Hi
When you have Data guard in 10g Rel 2 and your primary database protection mode is configured as MAXIMUM PROTECTION , when the standby database goes down , the PROTECTION_LEVEL in primary database changes to RESYNCHRONIZATION before the primary database shuts down .
SQL> select protection_level from v$database;
PROTECTION_LEVEL
RESYNCHRONIZATION
I need to know for how long primary database can stay in RESYNCHRONIZATION level before it goes down ? and how we can change this time ???
Thanks

Edited by: kamranbs on Jul 19, 2011 3:09 PMSomething not quite right, unless you have extremely slow disks or the OS is slacking (using VM?) . As soon a the net_timeout expires, primary initiates shutdown abort which should be instant.

IE 11 Internet Security Zone Protected Mode Problem
Hi All
We have a couple of random issues using IE 11 and was wondering if someone could shed a little light on it.
I think it boils down to an issue of the running of java but it's hard to pinpoint.
An example of the issue is present the below Technet article, it has expansion arrows on the left of the text that allow you to expand and collapse articles, this work in older version on IE and also other browsers, however in IE 11 they do not work until
you uncheck protected mode from the Internet Security Zone:
http://technet.microsoft.com/en-us/library/gg398125.aspx
If left checked these not work, this issue manifests itself in various different ways depending on the site but the above is the clearest example. Scripting of Java applets is enabled as part of the default Medium-High setting.Hi,
regardless, click the "Reset all zones to default" button... by default only sites in the RESTRICTED zone will have ActiveScripting (javascript) disabled.
I would expect it to be in the Internet zone... Are you MSFT? Intranet sites are usually detected automatically. It is uncommon to have a public access website listed in your Intranet zone sites list. If so please contact your system administrators.
or check if its in your list or applied by your network administrators.
Internet Options>Security tab, Local Intranet zone button, Sites button, Advanced... If its in your list, remove it... if its not in your list consult your system administrators....(it is not visible to you if they (the system administrators) have placed
it there.
Commonly....sites like TechNet or MSDN may be added to the TRUSTED sites lists.. On server versions of IE, Microsoft.com is placed in the TRUSTED sites list... Server versions of windows have a higher security, and MS.com is placed in the
On private computers there is little need to place sites in any security zone.... they will map automatically to the internet zone. Placing sites in the Trusted zone actually DECREASES the site security... hence you have to TRUST them first before putting
them into a lower security zone.
