Dataguard Protectin Mode

Hi,
I just would like to understand as how Dataguard protection mode works. I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter as below. But I have not changed the protection mode. I do not know whether there is any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY".
Your clarification will be appreciated.
log_archive_dest_2 =
SERVICE=O01CAS3DR VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=O01CAS3DR LGWR SYNC NOAFFIRM
sql> select PROTECTION_MODE,PROTECTION_LEVEL from v$database;
PROTECTION_MODE PROTECTION_LEVEL
MAXIMUM PERFORMANCE MAXIMUM PERFORMANCE
Set Appropriate Database Protection Mode:
You can choose between three protection modes, with different logging options. Each mode for your environment has a different impact on availability, costs, data loss, performance, and scalability. Choose one of the following depending on your service level agreements:
· Maximum Protection mode with LGWR SYNC AFFIRM option for an environment that requires no data loss and no divergence. Performance overhead is incurred.
· Maximum Availability mode with LGWR SYNC AFFIRM option for an environment that needs no data loss but tolerates divergence when sites are temporarily inaccessible.
· Maximum Performance mode with LGWR ASYNC (AFFIRM or NOAFFIRM) option for an environment that tolerates minimal data loss and divergence when sites are temporarily inaccessible. Performance overhead is minimized.

Hi..
Do you know at what time do you want to open the read only database.I thinks the steps will be
1. alter database recover managed standby cancel;
2. alter database open read only;
This will open the database
After the batch report is done, then a script must be run where
1. shu immediate;
2. startup nomount
3. alter database mount standby database;
4. alter database recover managed standby database disconnect from session;
Now, you need to put all these steps in the script.

Configuring maximum protection mode in dataguard with oracle 10g

Dear All,
I am facing a big problem in my configuration for oracle dataguard in maximum protection mode. as per oracle documentation i have done the following.
on the primary database i configured the floowing parameter.
LOG_ARCHIVE_DEST_2='SERVICE=CDER LGWR SYNC AFFIRM
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=CDER'
on the standby i configured the following parameters.
LOG_ARCHIVE_DEST_2='SERVICE=REDC LGWR SYNC AFFIRM
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=REDC'
i created standby redo logs on the standby database as per documentation.
I shut down the primary database and started it in mount stage and i executed the following commands.
SQL> ALTER DATABASE SET STANDBY DATABASE TO MAXIMIZE PROTECTION
after database was sucessfully alterd, i execute it the following command to open the database.
SQL > ALTER DATABASE OPEN;
what is happening is that i am recieving the Error end of communication channel and also after i look at the log file the following error is in place
Thu Jul 22 23:33:37 2010
Errors in file c:\oracle\product\10.2.0\admin\redc\bdump\redc_psp0_1088.trc:

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

If 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.

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?
Thanks

You 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:

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 reply

Anybody any idea ??????

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????

selva,

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

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

Something 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.

Database is High Protection Mode

Dear Friends,
I configured dataguard standby database in oracle 11g.Then i did the following scenario's.
1)I changed the protection mode to "High protection".
2)Shutdown the standby database.
As per the document, The primary database shutdown when standby database is down in High Protection Mode.
But my primary database did not shutdown. But if i fire "alter system switch logfile;", It get hangs. But parllely, I can able to login to primary db as normal user.
Can anybody explain what happen if database in "High Protection" Mode?
Thanks in advance.

Hello;
Can you post the results of this run on the Primary :
SELECT PROTECTION_MODE FROM V$DATABASE;The Protection modes are "Maximum availability", "Maximum performance","Maximum protection" They are described in detail here
1.4 Data Guard Protection Modes - http://docs.oracle.com/cd/E11882_01/server.112/e10700.pdf
If you search E10700-02 there is no "High protection" mode, so I'm not sure what you did. Maximum availability provides the highest protection, but also requires "SYNC" for your log_archive_dest_n parameter.
My own example is here :

Dateguard Protection Mode and log transfer doubt

Friends,
DB: 11gR2 (11.2.0.3) 64 bit
OS: OEL 5.5 64 bit
iam new to dataguard..
i just finished the setup of primary db and physical standby in my notebook.
the protection mode is the default one...that is...maximum performance. (primary)
in the maximum protection mode....whenever i need the logs to transferred to physical standby..i have to do the switch logfile and also archive the current log.
its not reflecting/transferring automatically. that is in the scott user i created a table in primary db..
but its not reflecting in the physical standby of scott user. once i do the below...
alter system switch logfile
alter system archivelog currentthen its reflecting in the physical standby. so, am i have to change this mode to maximum availability or maximum protection?
so in maximum performance mode, i have to execute the above statement whenever i need the log transport from primary to standby?
thanks

1. is the real-time apply can be used in all the 3 protection modes?Yes.
2. while changing the protection mode, i have to do it in the primary db is it?Yes changes are done in primary database.
http://docs.oracle.com/cd/B28359_01/server.111/b28294/protection.htm#
3. while shutting down the physical standby and primary i just run the shutdown immediate command in standby and then in primary...is there any steps to be followed while shutting down the server or starting up the server in the dataguard environment like rac environment.?
While shutting do this:
Check whether primary and standby database are in SYNC and then Cancel the recovery process
Shut down the primary database and then shut down the standby database And if you are using ASM then you have to shutdown that also.
Stop all listeners and cluster services. Perform this step on all nodes in an Oracle Real Application Clusters (Oracle RAC) environment.
While starting do this:
Start the cluster services and listener
Start the ASM and then database
Start the recovery process on standby database.

Database shutdowns in Maximum Protection mode

Hi,
I am using oracle dataguard 11g(11.2.0.1.0) on OEL5. My dataguard is working fine in MAXIMUM PERFORMANCE mode. But when i try to put my database mode in MAXIMUM PROTECTION MODE my database gets shutdown.What could be the possible reason for this????
Regards,
007

Hello;
Quote "To ensure that data loss cannot occur, the primary database will shut down, rather than continue processing transactions, if it cannot write its redo stream to at least one synchronized standby database"
Section - 1.4 Data Guard Protection Modes - Data Guard Concepts and Administration 11g Release 2 (11.2) E10700-02
From section 5.1 of the same document ( Maximum Protection )
"Oracle recommends that a minimum of two standby databases be used to
protect a primary database that runs in maximum protection mode to prevent a single
standby database failure from causing the primary database to shut down."

How do I troubleshoot Flash Player's protected mode for Firefox?

Starting with Flash Player 11.3, a protected mode was added as a new security enhancement for Firefox 4.0 and greater on Windows Vista and higher. This security enhancement is designed to limit the impact of attacks launched from malicious Flash content (SWF files). For additional details on this feature, please see Inside Flash Player Protected Mode for Firefox
After reviewing this FAQ, we'd appreciate if you would take a minute to let us know if it helped. There is a link to a two question survey at the bottom of the page.
While we believe this feature is fully tested and reliable, if you encounter issues with Firefox we recommend the following troubleshooting steps.
Problem: Flash content does not appear, YouTube display errors such as "An error occurred. Please try again later.", or Flash video will not function properly.
Solution: If RealPlayer is installed on your system, please disable the RealPlayer Browser Record plug-in.
Launch RealPlayer
Click the RealPlayer icon in the upper left corner of the window and choose Preferences.
Choose Download & Recording from the left hand panel
Uncheck "Enable Web Download & Recording for these installed browsers"
Click OK and close RealPlayer
Restart Firefox
If you are viewing this page in Firefox and Flash Player is not working, please click here for an HTML5 version of this video: YouTube HTML5 HD Link
Problem: RealPlayer is not installed, Flash Player crashes in Firefox
Solution:
Troubleshoot Extensions and Add-Ons by launching Firefox in Safe Mode
1. Exit Firefox
2. Click Start > Run
3. Type the following then press [Enter]:
firefox.exe -p
4. Click Continue in Safe Mode
5. Attempt to reproduce the problem
If the problem does not occur in safe mode, please try to isolate it down to an individual plug-in.
1. Exit Firefox
2. Re-launch Firefox
3. Click Firefox > Add-Ons > Extensions
4. Click Disable on all of your extensions
5. Attempt to reproduce the problem, while enabling each extension until you can reproduce the issue
If the issue persists in Safe-Mode, please continue with the steps below:
Some users have indicated that random crashing stops when clearing their Firefox profile. This step will allow you to temporarily test with a clean set of Firefox preferences, without losing your preferences.
Exit Firefox
Click Start > Run
Type the following then press [Enter]: firefox.exe -p
Click Create Profile
Click Next
In the Enter new profile name dialog, type "Test"
Click Finish
Select Test and click Start Firefox
Use Firefox as normal. If the problem goes away, clearing your Firefox preferences, or migrating the important settings (bookmarks, etc) to a clean Profile may be a good permanent solution.
If the problem persists, switch back to your old profile by doing the following:
Exit Firefox
Click Start > Run
Type the following then press [enter]:firefox.exe –p
Choose your old account (typically "default")
Click Start Firefox
Solution: Try a clean Windows profile (You must be an Administrator to complete this step. If your user account is not an admin type, skip to the next section for instructions on reporting a bug.) Creating a new Windows user will rule out any account-specific preferences that may be enabled on your system.
Create a user account in Vista
Create a user account in Windows 7
Use Flash Player normally. If the problem goes away, this indicates a compatibility problem, either with software you have installed or with preferences set on your account.
Reporting a bug:
Please file bugs at bugbase.adobe.com.
Choose "Adobe Flash Player" as the product
Choose "Browser Integration" as the product area
Please provide as much information as possible with what you were doing before the crash and an exact URL where the crash occurred.
If available, please attach your Firefox crash logs to the bug using the Attachments field.
Show hidden files and folders. For more details, see the instructions for the operating system that you use: Vista and Windows 7.
Crash logs are located at C:\Users\username\AppData\Roaming\Mozilla\Firefox\Crash Reports\
Logs will be located in either the pending or submitted folder, depending on whether or not you submitted the crash report to Mozilla.
Last resort
Finally, if these problems are blocking you from using Flash Player we recommend, as a last resort, you either revert back to Flash Player 11.2 or temporarily disable Protected Mode. We strongly recommend that Protected Mode is manually enabled once this issue is resolved.
To revert to a previous version of Flash Player, please see this FAQ: How do I revert to a previous version of Flash Player?
To disable Protected Mode, add the following line to your mms.cfg file located in:
Windows 32bit: C:\windows\system32\macromed\flash
Windows 64bit: C:\windows\syswow64\macromed\flash
ProtectedMode=0
If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)
Depending on your operating system, you might need to first save the mms.cfg file to a writable location (such as your documents or desktop folder) and then copy the file into the destination folder using Windows Explorer.
To re-enable Protected Mode, simply remove the line from the mms.cfg file.
Hopefully this FAQ helped you. Please let us know by taking a minute to fill out this simple survey.
Did this FAQ help?

Please ask your question on a forum for the Flash Player

Can you open Adobe Reader by itself? If so, try to disable Protected Mode [Edit | Preferenes | Security (Enhanced)].

Every time I open Reader XI I get a box that pops up and says "Cannot open in protected mode due to

incompatible system configuration"

Hi sdc01522,
Please help me in understanding your problem better as on normal Win7 machines we don't get these issues.
Can you please let me know the following:
1) Exact operating system like Win7 or WinXP or Win8 (32bit or 64 bit) (Home, Professional, Enterprise or Ultimate) (Goto Computer , right click and you'll see the details in Windows Edition and system)
2) Any antivirus/ antimalware/ encryption software installed in your system? (It might be stopping Adobe Reader to open with protected mode enabled)
3) Are you login with any specific kind of user or normal administrator user ?
4) Is your system a part of any special file system?
5) Have you installed Adobe Reader at the default location (For 32-bit systems it is C:\Program Files\Adobe\Reader 11.0 and 64-bit it is C:\Program Files (x86)\Adobe\Reader 11.0 ) or any other location?
Thanks,
