• error 105: could not resolve the address of the DNS server

  error 105: could not resolve the address of the DNS - why what it means and how to fix it?

  I get this message usually one or two times a day, usually in the afternoon, when I try to go to the internet.  I can use IE or Google Chrome - always get the message.
  Eighty-five percent of the time, I get very well connected.  But when I get this message, I unplug the cable modem from the power strip, wait 10 seconds, plug it in and after a few minutes, I'm connected to the internet.  How to solve this regular error?

  Hello

  You have to contact your internet provider (ISP) as DNS are usually associated with ISP. Have they reset their modem or router not only feeding cycle?

  Did you try the following steps below

  Start > all programs > Accessories > command prompt. Do a right click on it and "Run as Administrator". Type follows and press ENTER: ipconfig/flushdns

  Have you worked from the link I provided?  (I don't think you have time to do).

  It is possible that your tnsnames.ora is corrupted by some weird characters printable somewhere.  In some versions of the oracle, he might be sensitive to spaces vs. tabs.  If in doubt, netca to add entries, rather than doing it by hand.

  I've learned to trust in your obfuscation you covered something important, or you are showing some apples and oranges.  Error to declare you come from not being able to find referenced in tnsnames.ora entry, but the way you say you created your link db, you hardcoded the entire connection, so he never users tnsnames.ora.

  I would change the definition of db_link

  create the database link * _DBLINK

  connect to the USER IDENTIFIED BY 'user '.

  using "REM."

  Then create an entry in your tnsnames.ora

  REM =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = *. *. *. *)(PORT = 1521))

  )

  (CONNECT_DATA = (SERVICE_NAME = REM)

  )

  )

  Also, use server name instead of the HOST = IP address

  The closer looks that you can miss brackets final closing on your original definition.

  It is misleading to the column sequence, sequence of real number is 65 series, but it's beyond. Have you restored any old backup with the incarnation?
  When you perform incremental backups, is the current_scn in the two primaries and Eve was balanced?

  And the sequence number * 29 * is transferred from the primary to the standby (or) he has been removed from the primary?
  Perform the two methods.

  (1) SQL > alter system set log_archive_dest_state_2 = 'reporter ';
  (2) conduct 3-4 log switches
  (3) SQL > alter system set log_archive_dest_state_2 = 'enable '.

  and displays the alert log database and backup files.
  And you mentioned the hostname in the entries of the listener, if this entry is added in/etc/hosts? otherwise you can use the IP address instead of the host name and then reload the listener.

  second method
  (1) copy archives missing from primary sequence of 29
  (2) place manually and then perform a recovery
  or
  (3) retrieve manually

  And update with your conclusions after all these lists.
  Thank you.

• OBIEE 11 g, ORA-12154: TNS: could not resolve the connect identifier

  HI forumer,
  
  I installed obiee 11g and I am trying to connect to oracle 11 g db installed on the same machine. I am able to create the DSN using the tnsnames.ora, but the same details used with obiee work not and fails with:
  
  ORA-12154: TNS: could not resolve the connect identifier
  
  Appreciate any help in this.
  
  Thank you

  This is a change in behavior when we have 10g and 11g. In BI EE 10 g, there was no Oracle Client delivered with BI EE. Thus, BI EE will use your Oracle DB client host to connect to the database. Usually not a problem in this case. But in BI EE 11 g, the software itself contains a client of 11.2 DB. Thus, when you try to connect to the database using the repository or the BI server, it will try to find the tnsnames entry in the customer Oracle of BI EE 11 g instead of your database. There are 2 options to work around this problem

  1. copy your tnsnames.ora {Oracle_BI1} \network\admin directory & {oracle_common} \network\admin directory (only the first is necessary because it is the ORACLE_HOME)

  2. or instead of the source tnsnames.ora entry, use the full expanded tnsnames as shown below

  (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 172.16.66.173)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = orcl)))

  Both of the above will work.

  Hello everyone.

  I already solved the problem (work until late Saturday).

  the solution was to install the latest version of the Oracle customer, namely: Oracle 11 g Release 2 CLIENT for Windows 32 (11.2.0.1.0).

  Now everything works OK.

  I also tested in Windows 7 32 bit (the .vi even and the same Oracle client). This will also OK.

  Thans a lot.

• Q10 Q10 blackBerry WIFI - browser error - could not resolve the host name

  Hello

  I use my Q10 while overseas for the Wifi only. My SIM card is in my 9900 (thank you BB not to tell anyone that BIS no longer works and WW BB roaming is not until after people buy OS 10 devices, anyway...) but I want to use the Q10 for Skype, browsing and Email while on WIFI.

  Skype works.

  Browser gives "Could not resolve the host name" and charge no emails.

  WiFi network is good (the 9900 is connected and works, as do other devices). I reset the phone, router, etc. etc.

  All to nothing does not.

  A telephone conversation of two hours with T-Mobile (from abroad) was unnecessary and disconnected.

  All DNS data seems to be there.

  Please help.

  Thank you

  Aviv

  Hello

  Problem solved.

  I have reset the router before, nothing helps. The only way I got it work is as follows:

  (1) turn off the router and wait for the phone to 'do not see' to the network in question.

  (2) turn off Wifi on the phone (menu setting and tap on wifi)

  (3) restart router

  (4) restart the phone

  After about 10 minutes, it is finally connected.

  Thank you all,

  I would BB would have simply kept the features of the 9900 and just made more attractive to the masses, instead of making an iphone with a keyboard...

• GLWB-10521: could not resolve the ASM label

  I see just a glance on the tnsnames file you are missing at least one sign =...

  You have

  You should have

  ORCL =

  There may be other issues too, but give that a try at first - you better run netmgr to allow oracle to create the file for you.

• AMT: could not resolve the connect identifier specified

  Hi guys, I have installed Oracle on Windows XP SP2 11.2.0.1.0 C:\oracle folder
  I use the ORCL service to connect to the database using SQL more. I am connected yesterday and it was very good. Now I get this error:
  
  ORA-12154: TNS: could not resolve the connect identifier specified
  
  Of course, this error is related to the file tnsnames.ora and identifiers of Service and not correct SID.
  
  Here are my tnsnames.ora

  Here's the sqlnet.ora

  All the world is facing something like this before?

  Also, with the sys user, I get error

  What is going on?

  The 'system' password includes a ' @' character?

  Can someone tell me what is the problem?
  
  Best regards

  It can be caused by the location of the TOAD software. The have you installed under "Program Files (x 86)? If Yes, then try to reinstall in a different directory, media in the path name can cause problems.
