10g , dataguard, em starts database ok but then cant read status
I am attempting to get dataguard up and running. The problem I am stuck at is that the Enterprose manage starts up the database with no problem but them the following message appears :-
#The database status is currently unavailable. It is possible that the database is in mount or nomount state#
I can however access the database perfectly and read tables using sqlplus !!
I am very confused about how to configure the listener.ora file . I suspect this may be the problem.
Here is some further info thanks !!
SQL> sho parameters name
NAME TYPE VALUE
db_file_name_convert string
db_name string MVM
db_unique_name string MVM1
global_names boolean FALSE
instance_name string MVM
lock_name_space string
log_file_name_convert string
service_names string MVM1
sp_name string MVM
SQL>
The following is the contents of the listener.ora file :-
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /export/home/oracle/product/10.1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = mvm1)(PORT = 1521))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
The database is definately not in the nomount or mount state
SQL> select OPEN_MODE from v$database;
OPEN_MODE
READ WRITE
SQL>
No, I'm just working through the procedure for configuring the master server first , the next step is to configure the standby database .

I was having some problems with my mac, safari and itunes was freezing alot. I have to force shutdown and when I tried to start up again i get to the login page, type in my password and it starts to load, but then the screen turns blue for a few seconds and it goes back to the log in screen. What should I do?
Please Help!!Somewhat similar problem:
Put in the password, hit enter, the screen goes blue for half a second, then goes back to login screen and carries on logging in as usual. Drives me mad. It doesn't happen with a fresh Lion installation, nor if booted into safe mode. On the machine in question it also happens to new user accounts.
I've removed all login items, including Startup Items and Launch Demons (pun intended) and Agents, I've compared system login plists with a fresh Lion installation - can't see differences. I've removed Little Snitch and PeerGuardian (no more third party kexts).
@Carolyn: I've done disk maintenance with DiskUtility and fsck and even DiskWarrior, cleaned caches, etc. etc.
Any ideas would be gratefully received.
Sorry for trying to hijack the thread (as it's not about Lion), but it seemed dead anyway. -
When I get to the login page on my macbook, I type in my password and it starts to load, but then the screen turns blue and it goes back to the login.
Iv tryed this numerious times still keeps going back to pasword. Can not get any further. Tried restart holding shift key.. still nothing. What do i do?Thank you for your help.
I couldnt get to the hard drive/ desktop. Soft login not even working. So i could not do any of that.
In the end i took it to Apple and its actually the hard drive on its way out. A common issue with that series of Mac. Funny seeing i dont use this mac much. However being 2.5 years old and out of warrently, Apple have recognise this issue with this series/ Model and installing a new hard drive at no cost.
Very luck and greatful. And not feeling so dumb that it was something i did or could troubleshoot myself.
Hope this helps others that it just might be your hard drive failing. -
I am having trouble accessing itunes store. It starts to load but then goes blank.
I can not access the Itunes store. It will start to load but then goes blank. Not sure what to do.
Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now. -
Pressing play on purchased downloads and it starts to download but then returns to the play button. This is for all the purchased items I have. However pressing play on previews works. Please advise.
Welcome to the Apple community.
A number of people have reported similar issues recently, many appear to have found a discrepancy of some kind in their account settings and making changes to these settings or simply resetting them has resolved the matter.
Check your account details are correct, check that you are using the correct details for Location, Region and Time Zone. You may want to change these settings and then change them back to see if that helps.
Also check your payment details, make sure your details are exactly how they appear on your credit card statement, you might also try changing some of those details, saving them and changing them back again.
You might also try logging out of and then back into your iTunes account (Settings > iTunes Store > Apple ID’s > Sign Out) and restarting your router. (Some have reported that after doing this, they need to check for rentals even though it may report that there aren’t any, after which rentals once again appear in the ‘movies’ feature)
Rentals should appear under their own heading in the ‘Movies’ feature, you might also check at Settings > iTunes Store > Check For Rentals.
At this point in time, I’m wondering if this could be related to (but not restricted to) the new feature that allows others to come into your home and use your Apple TV to download and play their content on your Apple TV without logging into their account on your Apple TV. The Terms of Use for iTunes Store content have always been to require you to only purchase and play the content from the store in the location where you live and to use a credit card registered in that location. Previously Apple seem to have been somewhat lenient on enforcing such restrictions, perhaps now they are not. However I don’t really have any evidence to support this suggestion, except that changes made to accounts in these areas do appear to be helping many.
If you are successful in resolving your problem, perhaps you would let us know exactly which action resolved the problem for you. If you are having this problem to begin with, can you also tell us your location. -
Facetime on ipod starts to open but then closes
On the iPod when I start to open FaceTime the program starts black background but then the screen automatically closes. If you look at the open Apps is still apears open but you can't use it. It will accept incoming, but you can not send out. iOS 8.1.2
Does the front camera work in Camera app?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: Back up and restore your iOS device with iCloud or iTunes
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I bought an iPad 2. The first charge i made Was from the 86% to 100%. After that i used it. But then i read and in some sites say that it has to be charged 24 hours. So Now i have that question i did it well of wrong?
You can charge anytime. You can also plug it in over night if you want because you can never over charge it.

i have upgraded my pages in my ipad but i cant read it when i send it to my macpro? do i have to buy the apps for my imac? If i have to can I revert to the old one meaning the pages before the upgrading?
If you have iWork 09, then the latest version should be available for free in the Mac App Store. If you have the new version on your iPad, then you'll need the new version on your Mac as well. The whole point of the latest version is that you can access and edit your files equally on iPad/iPhone, Mac, and also through the iCloud website.

Lightroom 5 version 5.0 starts out fast, but then slows my computer to a crawl. What to do?
I upgraded from Lightroom 4 to Lightroom 5 after the release version 5.0 came out. But it doesn't work well. It starts out fast, but performance rapidly deteriourates. And it affects every application running on my Windows 7 PC. I assume this is due to massive memory leaks. The only way out seems to periodically reboot my machine.
I've had this happen without doi
ng exports (which was reported as a cause of this behavior by others). I get it just using the Developer module and having many steps with many photos. Also with the Book module it happens very soon. Does anyone have a workaround until Adobe actually fixes their product so it works right?I'm having the same issue. I'm running the trial version, but in 3 days when the trial is over I don't expect to upgrade. LR4 works great on my machine. LR5... there's a problem here Houston. Fix it and then I'll think about upgrading.
BTW - the tool I had high hopes for - the enhanced spot heal/clone tool... good idea, but needs work. -
I downloaded an audiobook and it started working but then it stopped. Is there anyway I can redownload my audiobook so that it starts working completely?
This is a ridiculous policy and it interferes with how most people would listen to an audio book since they are quite lengthy. I'm traveling, so I throw the audio book on using my iPad and I get 60% of the way through the book on my trip. I come home, I want to listen to the rest of it via iTunes on my stereo through AirPlay. And this can't be done?
This is the last audiobook I buy from iTunes until they *fix* this... and it IS something that requires fixing whether that means negotiating more aggressively with the audiobook providers or changing something at the software layer. It completely ruins many peoples' experience!
It's funny because a friend of mine suggested buying it, then downloading it from a torrent just so I could use the book the way I wanted to use the book. Is it not sad that to create a positive overall user experience you have to resort to downloading something off a torrent?
iTunes is supposed to make things easy and accessible. I agree with jamusick's posting -- this isn't the vision Steven Jobs had for the future. This is a road block on the way there. -
my apps are not updating when I try it starts to load then quits then i get the msg that the app cannot be downloaded at this time
Hi tmcrae
First check that your device is not full, maybe you may have to delete some photos or apps to make space to do updates. if its not full then you will have to try pluging it into your pc/mac running itunes then doing a backup and restore. Then you should be able to do your updates.
Sorry but i cant think of any other way if its showing as installed already but is not there.
Hope that helps

For awhile, since the newest update, I'd noticed when charging the ipod (classic) that it stopped going to the charging screen and would stay on the Connected: Eject before disconnecting' screen. But, y'know, didn't matter to me, it still charged... until today when I tried to add music. Tried it many times, reset it... STILL wouldn't transfer songs... It would 'say' it was syncing, but then suddenly stop and stay on the same Connect: please eject before disconnecting' page. I did a couple of times get a message about scanning it but, after restoring that never popped up again...
So, I do a system restore on it and ofcourse THAT works, but it STILL won't sync! So, now I've got an ipod with no music that won't sync and because it's all gone on there, I'm not sure how to back up my stuff (should I need to re-install iTunes... Though I doubt it'd work...)... So, yeah, I tried a different cable too, still no luck...
There has GOT to be some way to fix this!
Please somebody help me out! I so freaking appreciate it you have NO idea!I think the problem is that the iPod got set to Manually manage music and videos. It needs to be set up for automatic syncing again. Just unchecking that Manually manage music and videos setting does not do it.
In iTunes 12, select the iPod in iTunes (using the device button), so that you see the iPod's "management" screen. In the sidebar (along left side of screen), there are two headings (Settings and On My Device). Under Settings, click on Music. To the right, you see the iPod's Music screen, where you tell iTunes how to sync songs to the iPod.
Check the box at the top for Sync Music. That turns ON automatic syncing for music. Below that, choose the option to sync Entire music library (assuming your music library fits completely on your iPod). Otherwise, you can choose the option to sync Selected playlists, artists, albums, and genres and make your selections below. Then click Apply. -
When I tap on my Facebook App on my IPad it tries to open up but then it goes right back to my home page and will not open up. All my other Apps work ok.How can I fix this ?
Try deleting the Facebook App and reinstalling it.

10g dataguard - physical standby database
Hi Guys,
DB1 <Primary> - Production
DB2 <Physial Standby> - DR
I will need to startup my DB2 in DR segment for testing.
If i perform the below, will it affect my Production DB? I need it to be up and running as well.
DR:
recover managed standby database cancel;
shutdown immediate;
startup nomount;
alter database mount standby database;
recover standby database until cancel;
alter database activate standby database;
thanksHi,
In 10g version, you can open database database with READ ONLY mode. In that case standby database
recieve primary generated changes but not apply .
I see you steps you using ALTER DATABASE ACTIVATE STANDBY DATABASE statement for activating database
Activate the standby database using the SQL ALTER DATABASE ACTIVATE STANDBY DATABASE statement. This converts the standby database to a primary database, creates a new reset logs branch, and opens the database.*
If you are not need convert standby database to primary database then , you must use only
ALTER DATABASE OPEN READ ONLY;
