    SQL Developer - Unable to connect to instances on LAN/wireless


      I have Mac OS Lion on my laptop with sqldeveloper running.

      Now, sqldeveloper is not able to connect to Oracle instances, when I am connected in LAN or wireless. It just takes forever and spits out the IO error with vendor code: 17002.
      But it works fine when I'm on VPN to the same instances. :(

      It was working on both conditions until a while ago..Not sure what changed. But I did ping for the IP address and hostname of the DB server as well as tried to do telnet. Everything works fine.
      Why is it not able t oconnect with LAN/wireless setting?

      Any idea? Pls advise.

      Thank you.

          Hi Chitra,
          maybe you can share some more infos here so we can try to support you?
          (please try to format the output properly for better reading - for blocks of technical output you can use {noformat}
          {noformat} )

          <li> what version of SQLDeveloper are you using?
          <li> what version of Database are you using?
          <li> please check if on your Database the parameters local_listener and remote_listener are set? if yes, please provide them.
          <li> can you please provide the relevant listener.ora config?
          <li> are is any kind of cluster setup involved?
          <li> as you mentioned "VPN" - is the "LAN" or "WLAN" you refer part of your corporate network or your private network at home?

          these are a wide range of initial questions - some might not be necessary, but I want to avoid a high number of question/answer roundtrips.
