  • What database server are you using? Oracle is the name of a company, that produces many database products. Are you using Oracle XE? – Burhan Khalid Jul 10 '14 at 06:51
  • @BurhanKhalid Since it's tagged `oracle`, and that tag is specifically for the Oracle RDBMS, it's reasonable to assume we're talking about that. – Frank Schmitt Jul 10 '14 at 06:52
  • I am using Oracle IDE 1.1.3.2769. – DLV Jul 10 '14 at 06:54
  • @Frank-schmitt agreed, but there is a big difference between [tag:oracle-xe], and [tag:oracle11g] in the context of this question. – Burhan Khalid Jul 10 '14 at 06:54
  • @lakhan That's the IDE you are using. Do you have a database server installed on your local computer? – Burhan Khalid Jul 10 '14 at 06:55
  • Yes. I have installed it. when i am trying for new connection it will ask for Conenction name and username , password. So i am not able to understand that from where actually i colud get that? – DLV Jul 10 '14 at 06:57
  • I have installed oracle 11g – DLV Jul 10 '14 at 07:00
  • You've only said you've installed a client, your IDE. That is really not the same as installing a server. You have to have the server software to create a database. Your IDE can only connect to an existing database. – Alex Poole Jul 10 '14 at 07:13
  • Can you please share the link from where i should install it. – DLV Jul 10 '14 at 07:14
  • If you have a remote database, you can install only client, then add remote database to tnsnames.ora, if you don't have a remote database you have to to install Oracle Database Server. So tell us, if you have remote database or not. – neshkeev Jul 10 '14 at 07:36
  • @zarastutra i dont have remote database. I need to install it on my local machine only. – DLV Jul 10 '14 at 07:38
  • @zaratustra See i have this installed in my machine : Oracle - OraClient11g_home1: -Application developlment -configuration and migration tool -integrated management tool -oracle installation products – DLV Jul 10 '14 at 07:40
  • Show us the file $ORACLE_HOME/network/admin/tnsnames.ora – neshkeev Jul 10 '14 at 07:42
  • @zaratustra There is no such folder oracle home, oracle installed in my machine contains only two folder Inventory and Bin.. – DLV Jul 10 '14 at 07:46
  • you have to install oracle server here two files for [linux](http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-linx8664soft-100572.html) and for [windows](http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win64soft-094461.html) download both files for your platform, extract into the same directory and run the file setup, it guides you through the installation process – neshkeev Jul 10 '14 at 07:50
  • remove the client, you don't need it – neshkeev Jul 10 '14 at 07:51
  • I found I couldn't install Oracle XE successfully on Windows for the same error. However running it via Docker worked great for me https://stackoverflow.com/a/48085168/1603489 – NaanProphet Jan 03 '18 at 21:15
