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

Your question of Windows 7 is more complex than what is generally answered in the Microsoft Answers forums. It is better suited for the IT Pro TechNet public. Please post your question in the TechNet Windows 7 networking forum.

Could not resolve the property in a stream, or a property nested in a stream
Hello

I have a CEP of the following structure project.

Entry card1-> Stream-> Processor1-> Stream2 1-> output adapter

Input adapter takes in the events of type OrderLine that has lineid as one of the fields.

In the processor I wrote code like

Insert into OrderLine
Select *.
Of
OrderLine as lineEvent
where
sandr.utils.ProcessorUtility.isbefore (lineEvent.requestdate, lineEvent.scheduleshipdate) = 'TRUE '.

In the code above sandr.utils.ProcessorUtility.isbefore is a java method that returns a string.

When I try to deploy, I get an error saying

Could not resolve the property 'lineEvent.requestdate' in a stream or property nested in a stream

But requestdate is a valid field of entity class OrderLine.

I am not able to trace what could be the reason for this. Please help resolve this error.

Thanks in advance for your time,

DB Link error: ORA-12154: TNS: could not resolve the connect identifier specified

Hi all
We need to make an entry in the tnsname.ora file in a local database to connect to the remote database using db link?

He throws me an error ORA-12154: TNS: could not resolve the connect identifier specified

Help, please.
Thanks in advance.

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.

Help! Could not resolve the address of the server: the requested name is valid, but no data of the requested type was found.

Hello
So I started with a Horizon view, so I apologize if this is a noob question. I wanted to try to put a security server in our DMZ, but before I put it in the DMZ I wanted to test whether customers would be on our network. So here's my setup:
Overview of VMware View Administrator 5.3.2 generation-188719
Same version for security server.
Windows Firewall is activated 'On' on all profiles on security and the server connection. (this might be important later)
Laptop with Horizon installed Client, Version 3.2.0 build-2331566
IPad Air2 with Horizon Client Version 3.2.0 build-2331566
On the Administrator display > display Configuration > Security servers > change on the Security Server
I PCoIP Secure Gateway set to the IP address of the Security Server (say its 192.168.1.10:4172)
Connection servers > edit on the login server
I also have the Security server defined as PCoIP Secure Gateway (192.168.1.10:4172)
Yet once I wanted to test it before I put it in the DMZ
So when I connect with the iPad, it works fine, I can connect, see all my connections and connect to just fine.
On the laptop, when I try to connect, I get the login screen where I put my user name and password (correctly, I might add ) and when I try and I get a connection error.
"Error: could not resolve the address of the server: the requested name is valid, but no data of the requested type was found."
I found the article KB VMware goes around the question: KB 2085365 (without help)
I changed the Secure Gateway on both safety and the connection to the server at each IP I can think of, but it still does not work.
Can someone give me an idea what can be wrong?
What is my firewall to connect to the server? (I don't remember if I had turned on firewalls when I installed the login server while they could not properly configured summer when I install?)
Any help would be amazing!
Thanks for reading!

I found the problem, it turns out that the network port to the Security server has been set for public and not private in the firewall. Thanks for the help!

I am sure of the following:

2 oracle6.staging entry is tnsnames.ora
3. I am able to connect to a remote database with: sqlplus kay/[email protected]

"ORA-12154: TNS: could not resolve the connect identifier specified" error executing the execution in CAD Plan.

Hi friends,
We do face-down question when executing the execution Plan in DAC for full charge. We are working on the project of modernization of the OBI Applications and my client has worked on this environment is a few days. Before this, they load to the source 'EBSTST' instance and now changed data for instance 'EBSWKLY '. We have changed the details of connection under the tab 'Physical Data Sources' DAC. Test the connection Source and target are good. We have added input TNS of EBSWKLY in the path: u01/app/oracle/oracle11g/product/11.2.0/client_1/network/admin.
ORA-12154: TNS: could not resolve the connect identifier specified

Function name: connect
[The database error: could not connect to the database using the [apps] user and the connection string [EBSWKLY].].
Please suggest me if I m done mistake anywhere...
Thanks in advance.

I was saying about the environment variables defined by you on the server of informatica/dac under the .profile or .bash_profile as below:

TNS_ADMIN = $ORACLE_HOME/network/admin; Export TNS_ADMIN

ORACLE_BASE = / home/oracle/app/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/11.2.0/; Export ORACLE_HOME

ORACLE_SID = InstanceName; export ORACLE_SID

Path = $PATH: / usr/sbin: $ORACLE_HOME/bin. export PATH

LD_LIBRARY_PATH=.:$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

CLASSPATH = $ORACLE_HOME/jlib: $ORACLE_HOME/rdbms/jlib. Export CLASSPATH

Here are some examples I mentioned everything. You can set them in the user profile from which you installed the server informatica/dac.

If it is a CAR Forum, try to set the value of the instance-specific SID for example: orcl11 or orcl12 or orcl13... try to connect to each instance. Sometimes the general SID does not recognize configuration

The issue ended up being with the control file. I followed of many blog posts on how to roll forward the database before and they all said to restore the control file before you recover the database. I followed this paper: http://docs.oracle.com/cd/B28359_01/server.111/b28294/rman.htm#CIHIAADC and it worked as expected. The old control file has had 6 data files that were in a different place than the others. The new control file, I created the primary had all the files of data in one place. After correcting the control to point to the locations correct datafile all started working again.

Workstation 8: Upload failed: Curl error: could not resolve the host name

I have workstation 8 connected to our ESX host, it shows all the machines and allows me to connect to their end. But when I try to copy/paste/drag and drop a local virtual machine over there he said "Vmware workstation 8: Upload failed: Curl error: could not resolve the host name.
Someone at - he fell on this or have any ideas why this would be. I think that if it does not find the host name, I could not navigate or connect to my Virtual Center.

Hello

Whats is your ESX host name? I would recommend using with full ESX host name during the connection. You can connect to the ESX host using the host name, but to download the VM in this topic, you will need to use FULL of ESX host of domain name when connecting.

Please try to do it and let us know if it solves your problem.

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

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

Hello
I try to install Oracle Grid Infrastructure 12 c Release 1 on Windows Server R2 2012 in a hyper-v Lab (to my intention is to install a complete rac - later). I created my ASM storage with the role of ISCSI target (4 discs 20 GB each, all the dynamic extension), and they are all visible from both nodes. I can ping all the IP addresses of all servers involved. I required prior tasks, and there is one thing that I am invited to check. Error message is:
«Device checks for ASM - there is a control to check the devices specified in the requirements for the ASM.» Error:

I opened Asmtoolg, and everything seems to be ok in there (all discs are stamped and are visible etc.). I recognize that this is a complex area, so I understand that it will be difficult to difficult to diagnose. I was really surprised to not find anywhere, any success on the internet for the GLWB-10521 error code well. Does anyone have ideas of things I could try?

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.

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.
