The redo apply seems not work

I use Oracle 11g r2 configure a data guard and fast_start fail over (using data guard broker) environment on linux.
The standby database only sync the data from the primary if
1. Issue 'alter system switch logfile;' on primary machine.
2. Cancel the redo apply and restart it on the standby.
And real-time redo apply can't start, when I issued 'ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE', the sqlplus is hanging and no response.
And in the broker, there always following warning:
Databases:
orclPri - Primary database
Warning: ORA-16829: fast-start failover configuration is lagging
orclStd - (*) Physical standby database
Warning: ORA-16829: fast-start failover configuration is lagging

As a quick test, go to the primary and say
SQL> select * from v$log;then connect to the standby and say
SQL> select process,status,sequence# from v$managed_standby;Show the output here with copy & paste. Also the output from the primary of
SQL> show parameter log_archive_dest_2or another destination you have setup to reach the standby.

    Hi , can anyone tell me ,what to do as my iPhone 4S , suddenly, seem like hanged, I could not open or close my iPhone 4 S.
    The phone touch screen can not activate lock in or lock out. So I could not use this phone at all.
    Hope Apple Service can help me. What to do or visit their Apple agent in Singapore.
    Thanks.. Stevchin.

    RESET DEVICE
    Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost).

  • I had to uninstall V26 and installed V25.1 as the download pannel seems not working

    The files would download but are not seen in the download pannel which remain empty as though nothing has been downloaded.

    I hate new download because you don't know a corrupt file. It's stupid to show only filesize. It look like the programmers have power mind to know which files are really 100%.

  • My mac book pro fell of my desk, everything seems fine, but the dvd drive is not working properly, any suggestions

    My mac book fell of my desk yesterday. All seems well, but I noticed today that the dvd drive is not working properly, it seems to want to keep ejecting the disk even when the disk is out, and it won't accept dvd's any more. Any suggestions o fellow apple users?

    Back up EVERYTHING, then take it in to have them assess for any latent damage. Wouldn't want a similar "delayed reaction" from the hard disk drive, would we?

  • The time limits on the parental controls do not work. Apple does not seem to know how to fix this issue since the problem has been going on since at least leopard.

    The time limits in the parental controls do not work. I have several mac systems and they do not work on all of them. Also, I have had this problem since at least snow leopard and it is very frustrating that Apple is unable to fix a simple issue like this. All they have to do is somehow 'hard-wire' the time limits to the system clock but they are not listening. I used the feed-back feature in their support webpage and hopefully everybody else experiencing this issue will too. Thus, if they get a thousand notes on this issue they might listen and finally fix it.

    Well, the whole system with those time limits are funky. Sometime this happens, sometime that happens. When the user is on the bed time limits do not work nor do the length of time limits. It is very frustrating as one of the reasons I bought an apple in the first place was those parental controls which did not exist in Windows prior to Windows 7. I do have a Windows 7 machine now and the bed time limits work there. Maybe you have a Windows 7 machine as well and can let them use it.

  • Resuming the REDO APPLY : 10g and 11g Differences

    Versions > 10.2, 11.2
    OS > Solaris
    I have a question on step4 below.
    Both in 10g and 11g versions, for a Physical Standby DB, you
    Step1.
    Mount the DB using
    startup nomount; 
    alter database mount ;Step2. Start the REDO Apply using
    alter database recover managed standby database disconnect from session;Step3. Open the standby DB using
    recover managed standby database cancel; -- stop the redo apply
    alter database open ;
    Step4. Resuming the REDO APPLY
    alter database recover managed standby database using current logfile disconnect ;At this point (after step4 ), for 10.2 version, the standby DB goes back to mount mode , but the 11.2 DB remains open for READ ONLY queries because of ACTIVE DATAGUARD feature. Am I right ?

    Yes, you are right.
    In 10g, there is no option of active dataguard (redo applying is not possible when the database is opened). Redo applying is possible only when the standby database is in mount stage. When the database is opened in read only mode, the archive applying is not possible. In order to run queries on database tables, in a physical standby database, one had to stop the log apply and open the database in read-only mode. This means that the log files are being queued up during that period and will have to be applied once the database is reverted to the managed recovery mode.
    In 11g, this is not the case. It allows users to have read-only access to the physical standby databases. This option gives customers the flexibility to run queries to the physical standby database, while the log shipping and apply continues its work.The archive applying can be done even when the database is opened in read only mode. This option is known as Active Dataguard (Oracle High Availability). For this, the steps you have mentioned are perfect. This is the advantage in 11g.

  • I have recently upgraded my iMac Intel G5 iSight to OS 10.6.8 and now the internal mic does not work with skype or facebook. I can here static when playing back clips. Do I need to update firmware or reload old sys parts

    I have recently upgraded my iMac Intel G5 iSight (iMac5,1) to OS 10.6.8 and now the internal mic does not work with skype or facebook. I can here static when playing back clips. Do I need to update firmware or reload old system parts. I have zapped PRAM. The blue indicator in system audio panel will appear for a second as I slide the bar for internal mic but then it disappears. Is there a fix?

    The sound seems very faint but can here static on playback.

  • Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work.

    Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work neither when chosen after pressing the button nor chosen in the apple menu..

    I have had the same problem but on another forum it was suggested that disabling internet sharing would solve this. This fix seems to work on my machine - why it works I do not understand

  • The Port : 6001 is not working in the system

    Hi Experts,
    OS   :  AIX 6.1
    SAP :  SAP Netweaver EHP1
    In the OS level the Port : 6001 is not working and giving the out put as...
    pb2adm> telnet abcprdpb2 6001
    Trying...
    telnet: connect: A remote host refused an attempted connect operation.
    Virtual host : abcprdpb2
    As it is the BI java stack system & I configured the SMD & wily in the system. From the BI java stack system the wily agent is not working and it uses the port : 6001.
    Now the issue is regarding to the port : 6001
    when telnet in the same system which is Virtual host : abcprdpb2 is not working and which I have given the output above. It is working when I telnet to the other systems. Please see the output  below...
    pb2adm>  telnet abcprd001 6001
    Trying...
    Connected to abcprd001.
    Escape character is '^]'.
    Connection closed.
    From other system  virtual host : abcprd001
    As I have checked with the firewall team and said it is fine in the system and same us AIX team also. But still port : 6001 issue is not resolved in the Virtual host : abcprdpb2
    Can you please let me know how to open the port : 6001 in the Virtual host : abcprdpb2 and also how we can confirm that port : 6001 is opened or blocked in the Virtual host : abcprdpb2.
    Thanks & Regards,
    Sandeep.

    Hi,
    The both mentioned virtual systems are in different LPAR's (Physical host).
    Already I have checked the /etc/services and looks every thing is fine in the file. I have also checked the file inetd.conf  and I didn't find any thing # on the Telnet.It seems every thing is fine in the both files.
    Can you please look in to it and provide some thing which I have to look in the OS level.
    Thanks & Regards,
    Sandeep

  • How do I delete photos and photo albums from my iPhone? The instructions given do not work. No "delete" symbol appears next to the album name, and no trash can icon appears below most of the pictures the computer just put on my new iPhone 4.

    How do I delete photos and photo albums from my iPhone 4? The instructions given do not work. No "delete" symbol appears next to the album name when I press "Edit," and no trash can icon for me to click appears below most of the individual photos in the albums the computer just loaded on my new iPhone 4. When I synced the new phone the computer added these photo albums without permission from me. They are now taking up about 3 GB of memory on my phone. I would like very much to get rid of these photos from the phone. How do I do this?

    To delete photos from your device
    In iTunes, select the device icon in the Devices list on the left. Click the Photos tab in the resulting window.
    Choose "Sync photos from."
    On a Mac, choose iPhoto or Aperture from the pop-up menu.
    On a Windows PC, choose Photoshop Album or Photoshop Elements from the pop-up menu.
    Choose "Selected albums" and deselect the albums or collections you want to delete.
    Click Apply.

  • I have tried everything, but still I can't locate the photos tab in iTunes...I have tried changing the resolution, started iTunes after connecting with the ipad2, nothing seems to work! please advise!

    I have tried everything, but still I can't locate the photos tab in iTunes...I have tried changing the resolution, started iTunes after connecting with the ipad2, nothing seems to work! please advise!
    I am also providing you with a screenshot of what appears! I need photos on my iPad2
    Message was edited by: angana

    You don't see it on the left-hand side of iTunes - you need to connect and select the iPad on the left-hand side, and then one of the tabs on the right-hand side that you use to select which content to sync to the iPad should be Photos : http://support.apple.com/kb/HT4236
    You will need to select and sync all the photos that you want on the iPad together in one go as only the most recent sync remains on the iPad, not including photos in a subsequent sync is how you delete them from it.

  • The UniquekeyValidator Rule is not working in the EO edit dialog.

    The UniquekeyValidator Rule is not working in the EO edit dialog. We have Jdeveloper9i V. 9.0.3.2. The unique flags are checked in the primary key attribute and the custom message is never showed.
    Is there a Known bug about that? if yes.. does exist any patch to fix that?
    Thank u

    Thank u for your answer.
    Yes, of course .. i�ve already apply the unique key validator for the entity.. so that custom error message is the error im trying to get in the application.
    Other issue is when im trying to edit that error message: when im going to edit the message the previous error im entered is not there. Is it normal?

  • The ringer setting is not working on my iPhone 4s

    My iPhone fell into my pond for less than 10 secs. I pulled it out in time to dry it off and shake some of the water out. I made sure the screen was still working and sounds were functioning then I turned it off and left it in a bag or rice for 24 hrs. The next day I took it out and it was working fine. Now suddenly today, the ringer setting is not working. When I go into settings>sounds I press on ringtone and it seems to be working. Speakers are fine and when someone calls I have no problem. I can also hear the ringtones. But when someone txts me or when I get notifications it doesn't have any sound? The alarms don't work and the sounds in apps don't work. When I put the charger in, it doesn't make a sound. It vibrates only except when someone calls me... My headphone jack seems to be working fine because I can hear everything even the text tones and sounds in apps... What should I do? How much will I have to pay to get someone at apple to fix this problem? I'm assuming there is still some moisture in the phone maybe? It was working for a week until today I'm not planing to upgade to the iPhone 5 anytime soon. Btw, the volume buttons do work it's just when I press on it, it doesn't show the bars when you press up or down... it's just blank.

    If it's physically stuck it might be best to bring it into the Apple store at George Street Sydney.
    Set up an appointment with the Apple store via the website http://www.apple.com/au/support/contact/
