Connect-time failover

Can anyone clear me the concept of Connect-time failover and other failover's??

you are trying to start the listener on the machine that has enterprise manager installed.
Listener executable is available with oracle database software install( enterprise or otherwise).
You will have to pick the listener on a database software install box to configure it

CONNECT -TIME FAILOVER ERROR IN ORACLE 10G ENTERPRISE MANAGER

Hi All,
Please can anyone explain why I am getting this error and how to fix it?
I was trying this exercise to create a backup LISTENER to support a connect-time failover in Enterprise manager.The steps were .1)I clicked the Listener's link on Database control page.2)Next I clicked the Net Services Administration link.3)I selected listeners from the Administer drop-down list and clicked Go.
I received the ERROR message that "Listener administration cannot be performed, as this Oracle Home
"/opt/oracle/DB10g" is not a server installation.
Is this normal?
What can I do to fix it?Please help!
Thanks

Oracle 10g dataguard Connect-time failover Parameter 15 minutes

Hello,
we running a system with DataGuard in Maximum Availability protection mode and one physical Standby Database. There are two connections between primary and standby. I configured listener and tnsnames to perform a Connect-time failover in case one connection is down. In first place it seemed to work fine but since it has happened that the primary always hangs for exactly 15 minutes until the failover is performed. (ALL redologs need archiving)
I think this must be the default value of a Parameter but reading docs for hours I can't find it.
Can anybody help me?
Best regards
Fritz

It's like this. The connection failover I'm talking about is only between the primary database and standby database. I have two connections between them. That makes two addresses for the service (servicetostandby) specified in the log_archive_dest used by dataguard. In my case the log_archive_dest Paramater looks like this:
log_archive_dest_3 = 'SERVICE servicetostandby OPTIONAL LGWR SY
NC AFFIRM VALID_FOR=(ONLINE_LO
GFILES,PRIMARY_ROLE) DB_UNIQUE
NAME=standby REOPEN=10 NETTIME
OUT=9'
The tnsnames.ora entry looks like this:
servicetostandby =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = address1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = address2)(PORT = 1521))
(FAILOVER=true)
(LOAD_BALANCE=false)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = standby)
So if either address1 or address2 is down dataguard should use the other address to connect to the standby database.
Maybe because of the Maximum Availability protection mode the primary database does not perform if the standby database is not available. I'm not sure about that. But fact is that if I power off the standby database, the primary database hangs only for 9 seconds. That's specified in the net_time_out attribut of the log_archive_dest Parameter. So I'm quite sure that something in the oracle net service causes the problem.
With the "primary hangs" I mean: After the used connection (say address1) went down the redologfiles of the primary database get filled and then it stops for 15 minutes. The messages in the alert.log:
Thread 1 cannot allocate new log, sequence 1304
All online logs needed archiving
After 15 minutes the connection via address2 is established and everything works fine.
I hope I made myself clear this time and didn't confuse you totally.

Connect time failover fails with ORA-01033

Hi,
I have primary and standby databases configured. I want to configured connect time failover such that when there is role transistion. Clients can connect to DB with out changing anything in thier tns files.
Here is my configuration.
hosta primary
hostb standby
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL=TCP)(HOST=hosta)(PORT=1521))
SID_LIST_LISTENER =

(SID_DESC =
(ORACLE_HOME = /usr/oracle/product/11.2.0.3)
(SID_NAME = tstxx)
(SID_DESC =
(GLOBAL_DBNAME = test1)
(ORACLE_HOME = /usr/oracle/product/11.2.0.3)
(SID_NAME = tstxx)
listener.ora on standby similar expect changes in hostnames.
Tnsnames.ora client
ctf =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostb) (PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = hosta) (PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = test1)
Notice that I have place hostb address intenally first so that if failover/swichover happens. client connection will not error out

Hello;
I would review this document :
http://uhesse.com/2009/08/19/connect-time-failover-transparent-application-failover-for-data-guard/
The ORA-1033 hints you are trying to connect to the database in the wrong role. There's a trigger and some additional work which can prevent this.
Uwe's document should explain all.
The "SQL*Plus: Release 9.0.1.0.1 - Production on Fri Jun 22 17:38" is very odd. I would expect you would being using the client on the server is this not the case?
DBMS_SERVICE lets you define something like this :
ernie =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = primary.server)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = standby.server)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = ernie)
Check out "CREATE_SERVICE Procedure" here :

Thanks...

Connect time failover in Oracle Net Service

I have a problem. This is my tnsnames.ora file. I have 2 identical databases on 2 different servers
(alpha.it.telekom.yu and alphami.it.telekom.yu) with same service name tis.it.telekom.yu.
ALPHA.IT.TELEKOM.YU =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = alpha.it.telekom.yu)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = alphami.it.telekom.yu)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = tis.it.telekom.yu)
I use this net service name when my host alpha.it.telekom.yu is not in function, to bring me to the other host alphami.it.telekom.yu.
But what is my question. I have tested this net service name, it is in function, but my problem is in time i waiting to connect
to second host (it takes to much time) when first host is not available. Is there any parameter to set, so i can solve this problem?
Thanks.

I will try to clarify the problem. The second server (alphami.it.telekom.yu) is on the disaster recovery location and EMC SRDF technology is used to transfer data to this location. Thus, both databases are the same and must have the same service name. Information in tnsnames.ora file, I gave above, is correct by my opinion. I hope you better understand my problem. Thanks.

Itunes update to firmware fails, because connection times out.

I have been unsuccessfully attempting to update my iphone 3gs and ipad to iOS 5 for over a month now. I have spent many, many hours on this, and many phone calls to apple support. I disable Norton 360, and windows firewall, and my firewall on my router. I've tried updating my router's firmware, which bricked the router--thanks apple for insisting this was the problem, and I have replaced the router, with a new one. Itunes diagnostics gives me the following information. I am using itunes as the administrator in Windows 7, 64 bit, although itunes doesn't recognize it, unless I reinstall it as the administrator, but then once I restart the computer, itunes no longer recognizes that I using Windows as an admin.
Also, the firmware cannot update, because the connection times out, despite all my firewalls, and antivirus being turned off.
I've tried downloading iOS 5 and then updating using restore, but that didn't work. I've poured through support forums, and error codes: I get 1611, etc. Cannot seem to resolve this.
Any ideas?

I have a modem from my cable company that provides WiFi. When I try to connect time capsule to the modem via an ethernet cable I am unable to and I also lose my wifi connection

I have a modem from my cable company that provides WiFi as well as ethernet ports for internet TV and Sonos. But when I connect Time Capsule via an ethernet cable to the back of the modem I am unable to get it to work and I lose my wifi connection completely. I added Time Capsule to back up data and also to extend the reach of my wifi with an airport extreme hooked up by another computer.

Put the TC in bridge before you plug it in.. ie do the setup in isolation to the rest of the network..
I would also start a new wireless name on the TC so it is different to the cable router..
If you want to be exacting also set wireless channels so the cable router is set to say channel 1 and the TC set to 11 for 2.4ghz. Then plug it in.. you will have no trouble as the TC will get an ip address as part of the existing networking.. then extend the wireless using the extreme.

Message Mapping - connection time out

Hi ,
I hae just created a message mapping and when I click on Test tab and load a payload in source and try to test the mapping , it gives me connection time out error from java...
What could be wrong ? Mapping involves an XML to IDOC .
Cheers,

Hello,
I think so (Experts, please correct me if I'm wrong). Before, we had a scenario in which the external definition was about 960kb. It really did post issues when testing in the message mapping itself. There are three options:
a.) Use less detail in your sample message mapping, in this way you can correct the error in the mapping itself.
or
b.) Test in operation mapping, and then do the correction in message mapping afterwards. If the testing is successful, make sure that you don't click the drop down icon. Instead, export the result as a zip file and then extract it. (if this hangs, go for c)
or
c.) Test at runtime
Hope this helps,
Mark

Also, there may be other factors to consider depending on your scenario. If you don't have it already, look at the latest <a href="http://service.sap.com/~sapidb/011000358700005909032005E/XI30XI70_TroubleGuide.pdf">XI Troubleshooting Guide</a> - Section 9.2 on "Timeouts in XI".

Connection time out

Hello everyone,
I'm using modem PK5000 from Century Link. My other two desktops are using Window and in the same room w my modem.
I got connection time out every time my computer started playing the screen saver.
All I have to do is restarting my modem but it's so unconvinience.
I called Century Link customer service and all they told me is changing the channel but it didn't solve the problem.
At school and other people's places, my wifi works just fine.
I used cleanmymac about a month ago and this problem started a week ago.
Can cleanmymac cause the problem? If so, how can I check and fix it?
I check the apple store to update my software but everything is up to date.
Can it be the firmware of my modem? My brother who uses the two desktops (and they connect to the modem with LAN cables) upgraded firmware last week and it seems like when the problem started.
And when my Mac loses the wifi signal, my printer still has the signal, but my desktop cannot log-in to page 192.168.0.1 which manages the modem and wifi even though the desktop connects w my modem by LAN cable and it still connects to the internet.
If you have any clue, please help!
Thank you so much!

Thanks Todd, Wayne,
this network timeout sure seems to be the guilty one!
I've changed it, lets see if it's fixed but sure looks like it.
The thing is that I was looking for GWWS tuning here :
