What will happen if oracle listener is stopped and started again.....

Hi Gurus,
Please suggest What will happen if oracle listener is stopped and started again on a running SAP System ?
Thanks in advance.

Hi Lakhbir,
What will happen is that, all SAP work processes will loose connection to the database.
If any active jobs(background jobs, updates, insert to database ) are running, they may fail. All the work processes will go to a re-connect state.
( There are few notes on WP reconnect which you can check and read about)
DB Reconnect Parameters - SAP High Availability - SAP Library
Application will be running but users will not be able to do any activity or may not be able to login at all and may get errors like ( No connect to database possible)
As soon as you start the listener process again , all the work processes will connect to the database again.
This is because the WPs will keep on trying to connect to database at regular interval and as soon as the connection is available they will re-connect.
You do not have to restart any work process manually in SM50 or anywhere else as this feature is enabled by default until disabled manually.
Thanks
Amit

Has anyone else experienced the stopping and starting again while playing music in iTunes. It was fixed but with the last update it has started skipping again.

Has anyone else experienced the stopping and starting again whil playing music in itunes. It was working fine wit the prior fix, but after the last update
it started skipping again.

Try it in another vehicle see if it still happens, at least you can narrow it down to your phone or the car. My 4s play totally fine, I have never had any of those issues. Maybe its time to restore your phone and start over. I would also have someone else play their Iphone in your car, see if it happens to them. Or try yours in someone elses car. Good Luck!

Listener ( lsnrctl ) - stop and start just one instance

Hey all. I hava a Oracle 9.2 installed over a Linux Red Hat 4.0 64 bits server.
Some Virtual Machines will connect in some databases installed in my Oracle server. My listener has one instance for each database like this:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = VM01)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = VM01)
(SID_DESC =
(GLOBAL_DBNAME = VM02)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = VM02)
(SID_DESC =
(GLOBAL_DBNAME = VM03)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = VM03)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = VM01))
(ADDRESS = (PROTOCOL = IPC)(KEY = VM02))
(ADDRESS = (PROTOCOL = IPC)(KEY = VM03))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = lab2)(PORT = 1521))
And my tnsnames:
VM03 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = lab2)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = VM03)
VM02 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = lab2)(PORT = 1521))
(CONNECT_DATA =
(SID = VM02)
VM01 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = lab2)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = VM01)
I need to start and stop just one instance (VM01 or VM02 or VM03). I really can't stop all instances when I need to stop just one. And more if i have to create another instance i will have to stop the listener... and i can't because other people are using your instance...
Do you know how to help me?
Thanksssssss

You still use listener.ora, just create 3 listeners, one for each instance:
listener.ora:
LISTENER_VM01 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(HOST = lab2)(KEY = VM01))
(ADDRESS = (PROTOCOL = TCP)(HOST = lab2)(PORT = 1521))
SID_LIST_LISTENER_VM01 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = VM01)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = VM01)
LISTENER_VM02 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(HOST = lab2)(KEY = VM02))
(ADDRESS = (PROTOCOL = TCP)(HOST = lab2)(PORT = 1522))
SID_LIST_LISTENER_VM02 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = VM02)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = VM02)
LISTENER_VM03 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(HOST = lab2)(KEY = VM03))
(ADDRESS = (PROTOCOL = TCP)(HOST = lab2)(PORT = 1523))
SID_LIST_LISTENER_VM03 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = VM03)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = VM03)
Then, when you need to stop the connections to only one instance, you stop the corresponding listener:
lsnrctl stop listener_vm02
lsnrctl start listener_vm02
For each instance you need to configure the parameter local_listener:
sys@VM01> alter system set local_listener=listener_vm01;
sys@VM02> alter system set local_listener=listener_vm02;
sys@VM03> alter system set local_listener=listener_vm03;
And register in tnsnames.ora:
listener_vm01=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=lab2)(PORT=1521)))
listener_vm02=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=lab2)(PORT=1522)))
listener_vm03=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=lab2)(PORT=1523)))
It's a recommended configuration for the flexibility it provides,it requires a different port for each listener, but you don't need to edit the listener.ora file each time you need to stop the connectivity to only one instance.

How do I make a routine stop and start again without restarting labview?

I am running Labview 6i and am somewhat of a noob. I have a subVI designed to take information and write it in a file, but every time I stop this subVI it will not start again until I restart the entire VI. I would like to be able to start it and stop it and take multiple readings because I must leave the main VI running. The subVI is attached.
Solved!

I tried a couple of case combinations, and this one seems the most solid. Still, the while loop is not passing information.

How to make an effect stop and start again?

How do I make an effect start stop and than start again?
I'm trying to blur faces (I finally figured out how to do that---copy the video to a 2nd layer and use the mosiac and crop effects) but how do I make the effect only appear when the face is in the screen as multiple times throughout the video clip the subjects face goes off camera. In the effect controls window it doesn't give me an option to add a blank keyframe.
Any advice on how to have this effect start/stop multiple times in one clip??
Thanks

If the effect isn't keyable, try keyframing the transparency of the copy with the effects on it.

When I get unresponsive script what will happen if I select Don't ask me again

My PC often is running very slowly and it usually seems connected to a "Warning: Unresponsive script". I always select "Stop script" which usually sorts the problem and with no perceptible unwanted results. On the dialog box for the Unresponsive Script there is a tick box with "Don't ask me again". What action will the system take if I tick this box. Will it '''always''' cancel the script (which I want) or '''always''' continue (which I certainly don't want!)? I need a definitive answer please otherwise I could be hung up FOR EVER!

See:

* http://kb.mozillazine.org/unresponsive_Script_Error

When hearing sample songs they stop and start again.

When I try to listen to songs I may want to buy, the song starts and stops....why? Never happened till apple replaced my old ipad2 with this new one!

If the effect isn't keyable, try keyframing the transparency of the copy with the effects on it.

TS1424 I have downloaded a song and it will only play the first 18 seconds and starts again?

I downloaded Clique by Kanye West on itunes and it all appered normal until you try to play the song either on my computer or iphone it plays the first 18 seconds and then goes to the next song even though it says the song is 4:52 any ideas how to fix this?

Depending upon what country that you are in (music can't be re-downloaded in all countries) have you tried deleting it from your iTunes library and redownloading it via the Purchased link under Quick Links on the right-hand side of the iTunes store home page on your computer's iTunes ? Re-downloading.
If you aren't in a country where you can re-download music or if it re-downloads in the state then try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via Store > View My Account and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find that song and use the 'Report a Problem' link.

If a new apple id sign in.what will happen to the old apple id if you erase or reset the phone?

I buy a new iphone 5s and the store open it and put his apple id to download some stuff.. And after that i try to make my own apple id. What will happen if i erase all data and it is in need of apple id.. Will it be the old apple id or my apple id?? I heard that if i erase all data. The apple id of which i buy my iphone will appear and mine will not??

If the store setup the phone with an Apple ID/Password, that is not yours, & turned on Find My Phone, then you will need that Apple ID/Password to re-activate the phone. Called Activation Lock. Read here:
http://support.apple.com/kb/PH13695
So, go back to the store where you got this phone & have them fix things.

What will happen if I downloaded the iOS 7 in my ipad mini? What will happen to my data, photo and downloaded apps before (ios6).

The advice to back up is good.
And one other thing. If you don't currently use a passcode to use your iPad, I really recommend you set one up before you update. Just make sure you either know what your currently use, or if you set one up, you write it down somewhere safe for future reference.

What will happen to my playlists if I cancel my Family Subscription so I can add more subaccounts?

When I first signed up for the Family plan, I selected only two accounts. I've read that I will need to cancel my family plan and resubscribe so I can sign up for additional subaccounts. My question is, what will happen to all of my playlists and saved songs when I cancel my plan and then resubscribe? Thanks!

What actually happens when you "Manually manage music and videos"?

I'm afraid to try this option on my iPod, and here's why:
I am currently traveling for three months, and before I just left, I synced up my 80GB iPod with all the music I wanted (via playlists) and all my podcasts. I will not have access to my home computer for at least three months. However, I'd like to be able to sync up podcasts whenever I am at a computer that has iTunes installed (friends houses, etc..).
Someone told me I could do this by setting my iPod to "Manually manage...", and just add the podcasts I want, manually. Sounds good, but I'm afraid to try for fear that it will actually reset my iPod which would be disastrous since I don't have access to my music library on my computer.
Can someone reassure me that this won't happen?
-tanzbodeli

What I meant was, what will happen to the playlists, music, videos and podcasts already on my iPod when I change from 'syncing' my iPod to selecting "Manually manage..."? Will they be wiped out and my iPod given a clean slate, or will they remain there and I can then add to them?

Waveburner resets (64bit) IK Multimedia plugins when stopping and starting

Does anyone else happen to have this problem:
I'm finding that while mastering, I want to look back at the incremental changes made and have found that the Pultec EQ and some other plugins seem to default to a preset.
In order to get to this problem I did the following:
1 track in Waveburner, added the Pultec EQ,
2 added a limiter chose a preset 'MIX PRESENCE' then got my desired sound.
3 When listening everything seems fine and then you stop and start again, or go back to the beginning of the track by pressing the 'BACK ONE TRACK' button on the transport and all of the sudden the Pultec EQ resets to that original preset.
So not too sure what to do, the only way of getting round this issue was to mix as best as I could, save as a new preset while it was playing and then when hitting start again then while it is playing then I quickly hit the preset on that I made and have to bounce my mix at the same time in order to finally get my desired output which is less than okay.
Can anybody help. I'm running on an iMac, 64bit Version10.6.7 OS and Waveburner is 1.6.1
Many thanks

It is not just IK Multimedia and Waves plugs that are resetting on me; it is also the WaveBurner 'native' plug "Linear Phase EQ" and who knows how many others, were I to begin testing instead of trying to work through this.
This little bug renders this software effectively useless for professional work.
Some of my Waves plugs hold their values, others don't.
Elysia products screwed up too; so much for that demo.
As far as I can tell I am not using any automation, but, is there a way to globally turn off the possibility of automation (I tried RightClicking in the mix lane but there is no choice of automation available there, perhaps 'cause there is none as I suspect)?
I am using WaveBurner 1.6.1.
C'mon Apple, its November already; you must fix this.

Burned DVD issues in DVD player not reading or music issues stop and start

I'm a PC converted to a MAC (less than a month) and love it so far. I have been able to create and burn a DVD. The problem I'm having is one DVD player will not read the DVD (Hitachi). The other DVD player will play it, but the music stops and starts when it transitions (twirl) to another picture (Panasonic DVD/VHS combo). I'm using a DVD R Memorex. Neither one of the player are new. Would love to use this to make the Grandparent's a DVD of the grandchildren from birth to present as Christmas present. What do I need to use or do to be able to watch on any DVD player as well as the computers?

Hi me01
Welcome to apple discussions. Try using 99 photos / less to avoid issues with audio fades / drops. Also do a search for Memorex on this forum and you'll see it's not the first choice of dvd's for most users. Instead try Verbatim, Maxell, or Taiyo Yuden and burn at 4x from a disc image for best results. Wish you luck and feel free to post back with results or any further questions.

Some songs starts on my iPod, then stop and start from the begining and play all the way through

Hey,
While listening to songs on my iPod Classic 120gb, some songs will start to play, after 2-3 seconds, stop and start again from the beginning and play through the entire song no problems. On iTunes the songs still plays fine no stopping or starting. All songs are random artists and songs.
Help! its really frustrating!

Hey andy8299,
Do you have any other music software (i.e Limewire) installed? If so perhaps these files are not compatible.
See this for compatible song formats:
