Install of new problem-unable to connect to the server from a remote client DB.

Hi experts,

I am new to set up a server oracle so pls bear with me...

I have install a db Server (11g on top of Oracle Linux 64 bit) home (192.168.1.90 static). I checked that db, listener are running. However, I tried to connect to the server from a different client machine (192.168.1.108) within my home network, but the server is not reachable. I got a ping from client and the server using IP addresses and host names. I followed the following steps to troubleshoot but could not go beyond the step 3, the server on port 1521 telnet-ing. Can someone help me what I need to do to make the port # (1521) is accessible by the customer?


1. check with the 'ping' using the IP ('ping 198.11.34.43'
2. check with 'ping' using the DNS (for example "tnsping uranus")
3. try telnet to the IP address on port 1521 (telnet 1.2.3.4 1521)
4. check with "tnsping" using the TNS service name
5 call SQL * more of the line command «sqlplus fred@flintstone» operating system If this does not work, make sure your receiver is the defined service of flintstone.
6 sign - on to SQL * more and connect with the name TNS ('connect fred/flintstome@service_name'
7 in SQL *, try a select table@remote_db_link

Thank you very much in advance.

Hello
(1) problem can be because of the firewall. Please check if the firewall turned on for your environment
(2) check sqlnet.ora, you can allow requests only from specific systems

Thank you
Krishna

  • download problem 'Unable to connect to the server' iPad folio

    Too, I'll have a problem displaying the folios in Adobe Content Viewer v32.

    Other members of the team had trouble downloading the folio and received an error message "can not to connect to the server at this time...". "

    My diagnosis:


    1. I downloaded the folio to my iPad, no problem for me.


    2. their problems after update, so I've updated to v32. Then I started having the same problem.

    The download should start, the status bar it would be 1/3 diameter, will be first to go back to 1/3, then get to the error.


    3 think necessary v32 iOS8, took me to update that too. Same error message.


    4. I have read on this forum on the problems as those creating applications have been seen and the fix was on the server.

    Thinking the folio was to be reissued to work with v32, I deleted republished folio to folio online, downloaded in the folio again, producer and then tried to download it. Same error message.


    I'm out of ideas. The only solution I have is "no update". Looking for another solution.

    The team continued to investigate the matter last weekend and have identified the root cause and strive to solve the problem. There is a potential delay which can be met with the largest networks of content and/or slower.

    I don't an ETA have not yet but will keep you all.

  • At the opening of some Web pages I get a msg 'unable to connect to the server', but it works very well in startup

    The last few days during the use of the internet, some Web pages will not be not open. I get a msg of error saying 'unable to connect to the server', but it works very well with other sites such as Facebook and YouTube.  This happens when I use Safari, Firefox and Chrome.  Yet if I'm in Safe Boot mode it works fine.  I exaggerate the App installed VPN and when I am in normal mode and connect to the VPN exaggeration, all Web pages work correctly. I searched the net for days trying to find a solution but nothing I tried worked.  I'm not very computer savvy either so don't know much of what I do with this technical stuff.  I emptied the caches, but that did not work.  Following the advice of an answer to another question on this forum that was similar to mine, I went into the Terminal and performed a diagnostic test.  I don't understand all the information in this essay so hope someone here can decipher.

    Hi AussieEgypt,

    Thank you for using communities Support from Apple.

    If a problem does not occur when it is started in safe mode, then you have already determined that the problem was isolated to a few 3rd party software running on your Mac.  Take a look at the information below to start with the removal of some elements of start-up and connection and see if the problem persists:

    Test your login items

    1. Choose the Apple menu > System Preferences, and then click users and groups.

    2. Click on your account under the current user name, and then click connection points.

      Make a list of the login items, you will need to remember later.

    3. Select all the elements of connection, and then click the button Delete .

    4. Choose the Apple menu > restart.

    5. If this solves the problem, reopen the preferences users and groups, add the elements of connection one at a time and restart your Mac after the addition of each of them.

      If the problem persists, follow the steps above to remove only the last element of connection that you added.

    I am building a test for BDE configuration, and now I'm stuck with a problem.

    Problem: Unable to connect to the administration server Serengeti using BDE plugin in the Web Client. After you select the management server in Serengeti, when I click on OK, I get an error message "Connection Failed!". Screenshot of the error is attached.

    Things I've tried so far:

    1. I tried using IE, Firefox, but I get the same error.

    2 uninstall the plugin BDE, re-installed, but still the same problem

    3. DNS resolution works quite well.

    4. I am able to ping to/from all possible directions

    5. the VAPP has been deployed with the resources box initialize verified. In addition, SSO registration was made

    6. have you deployed nine VAPP a few times, but still the same problem.

    7. when VAPP is deployed without SSO registration, I can connect using Serengeti CLI, but of the Web Client, I always get the same question. Strangely, SSO 19.ne recording enabled, I can't to Serengeti CLI as well.

    8. as in the other posts, ran < EnableSSOAuth > command and restart the Tomcat service. Always the same question.

    9. have you restarted SSO, VC, paralytic, but not luck.

  • Unable to connect to the server

    I have an officejet pro 8600plus. When I bought it, I have activated ePrint and registered my printer, but never used the feature. Since then, I updated from XP to windows 8.1, changed a router and connected the printer through a series of switches on a wired ethernet connection. A few days ago, I tried to use e print but received a message that I couldn't connect to the server.

    my printer prints fine, connects to each computer on my home network, I just upgraded the firmware with success to [personal information deleted]
    and yet, for more than three days, unable to connect to the server. I even deleted my account eprint printer, after changing his email successfully, but now I can not add new, I can't get the code because I can't activate the web plus services. I can scan from the printer to files network and all, but can't seem to activate eprint.

    can anyone help?

    Thank you

    Hi the gills.

    Welcome to the HP Support forums.  I think since upgrade to 8.1 Windows and change your printer router cannot connect to web services to get the job of ePrint feature.

    Please define Manual of the printer an IP address manually and DNS servers. I've included a link to another post, I did it with the stages (including screenshots) how to do it.

  • 'Unable to connect to the server' msg on Palm Pre to the IMAP e-mail server

    I am trying to connect to a server of Courier IMAP on my Palm Pre. It happens to be a Lotus Domino 7 server, but I don't think that is relevant, unless someone can suggest a better Protocol IMAP (don't want to use POP, because I want access to records). I was able to use it very well on my Palm 750 (Win Mobile) and now for the test, on Outlook Express as a Windows client, so I know that the IMAP server does not work correctly.

    On the Meadow, when I press the "Sign In" button at the bottom of the page of manual configuration of account, I always get the message:

    Error

    Unable to connect to the server

    I am able to sync the Pre with EAS system based on Zimbra to my business and my personal Google gmail account without any problem.

    On the Meadow, in the manual configuration of the account, I entered

    E-mail type: IMAP

    nom_ordinateur.nom_domaine.com

    user name [no @domain.com]

    password

    Port: 143

    Encryption: no

    [And yet once again, I know that the values that I have entered are correct, because I just enter values in Outlook Express and it worked fine.]

    He actually let me same hit "Sign in" until I set up outgoing mail server also (which seems weird and as a minor bug - it should let me retrieve messages, even if I don't have an available SMTP server to send responses). So, I also implemented the mail out with authentication server. I don't know I have a valid for sending SMTP system, but let's assume that is not related to the error, as I just want to do my incoming mail and be able to deposit in the IMAP folders respective, at least for now. I'll worry send later.

    Initially, I left the empty root folder option. I also tried to put a "/" (single, slash, ignore the quotation marks) in there. No effect.

    (Question on semi - the Pre does support multiple connections EE without getting confused? In general (on Win Mobile anyway), you can only have 1 per device. If it was an option on the Meadow, perhaps I could empty Domino in favour of another Exchange Server, but this would be a term much more time here, I hope with my IMAP question).

    Thanks for any help,

    Colin

    It seems that you need a smtp server configuration that is valid for the step of the link set.  In the test here, if the SMTP connection is refused/incorrect login it will not create the account (verified by looking at the packet stream, newspapers of IMAP connection fine, SMTP connection refused, account refused on the Meadow).

    So now, it seems that you need a valid SMTP server in order to create an account.

  • Unable to connect to the server at this time!

    Hey guys,.

    We are experiencing a problem with our multifolio app. We continue to get this message when downloading folios: unable to connect to the server at this time.

    Now, normally we put this to a bad internet connection.

    This is not the case.

    We constantly download problems in this app. At the beginning it is seems to be very well; the blue indicator bar Scrolls merrily along until suddenly it stops and goes back initially, continues still for a bit and then, BOOM! Unable to connect to the server at this time!

    The funny thing is when I go to the Adobe Content Viewer that doesn't happen. Same files in the same place, but with a different application. It may take some time, but it does not stop and finally finished the job. I get the download.

    The name of the application is Reykjavik Shopping and City Guide.

    Any thoughts? This is a serious problem and could impact our business in a bad position.

    Thank you
