  Hi don,.

  Thanks for your reply.
  My question is, we would have to apply the hands on review after completing exams Developer OCA to get our certification in post?

  PL/SQL Developer OCA or same PL/SQL Developer OCP have one hand on the requirement of the course.

  You don't need to attend (yet) training for the latter.

  Search requirements @ http://www.oracle.com/education/certification (locate under Certifications... View all certifications).

• I can not connect db 11g PL/SQL Developer. I want to create the new database and tables. How?

  I can't connect to the database.

  PL/SQL Developer <> Oracle SQL Developer.

  But anyway...

  >I can not log on to db 11 g

  Why not? Is it because you don't have a database to log? You cannot use SQL Developer to create a database. You will need to use the database Wizard or SQL * more to it. Or you can download a virtual appliance machine that already has an installation of database on this subject...

  If you need more assistance in obtaining a database to learn with, I wrote a little more in depth here.

  Thanks guys, I managed to install Oracle 11 g 2 and I installed a database using dbca tool and I can connect to my database. One thing I noticed is that when I look in my tables in sql developer I see plenty of tables different i.e. def$ _, logmnr_, etc. and I don't know why did I expect an empty table.

  Thank you for all your help btw.

  One of the fundamentals of relational databases is that they use their own facilities to manage themselves.  This means that the database management system uses the database to manage data on the database using exactly the same facilities (tablespaces, tables, user accounts, procedures, etc.) that an application uses to store application data. See "data dictionary" so there is no such thing as a completely database empty.

  As said by others, you do NOT want to create your own tables under patterns oracle (users) or in the disc spaces logics own oracle (esp. SYSTEM and SYSAUX).  Create your own account user/schema.  Create your own tablespace. Do this by default tablespace for the user.

• Problem when creating new connection of database with SQL Developer

  Hi all
  
  I am a beginner and I want to learn Oracle add up to my learning
  I installed SQL Developer on Linux Mint 12 (lisa).
  The installation went well, but when I try to create a new database connection in SQL developer, I get the following error:
  
  * Status: Failed - Test has failed: IO error. The network adapter could not establish the connection.* *.
  
  Could someone please suggest where exactly, I'm missing?
  
  Greetings - Vishal

  Have you installed the oracle database software locally? Have you created a database called "oracle?

  Developer SQL does not include a data base. For learning purposes, I recommend that you download Oracle Express Edition.

• Unable to connect to Oracle XE

  Hello
  I know this topic has been covered many times before here, but...
  
  I have a copy of Oracle XE on a laptop computer that I hadn't used for a while. After he sailed the http:// < host >/apex/apex_admin home page, today, I can not connect SYS or SYSTEM? I can connect OK for DB XE by SQLPLUS using these accounts, so know I use the password, what could be the problem? I get "invalid credentials"?
  
  Thank you
  
  Mike

  Hello

  OK, so you have improved the Apex on your XE.
  After version 3.0, you cannot connect to the workspace with the user SYS or SYSTEM.
  You have the workspace and workspace users to operate with Apex.
  Even this link is for Apex 4.0, he explains the difference with Apex version provided by default XE 2.1 and later
  http://www.Oracle.com/technetwork/developer-tools/Apex/upgrade-Apex-for-XE-154969.html
  (I have not found page more where is the same but for Apex 3.2)

  You can control the instance of the Apex and all the workspace workspace IN-HOUSE.
  Connect to the workspace IN-HOUSE with the ADMIN user.

  If you don't remember ADMIN password, download 3.2 install files.
  http://www.Oracle.com/technetwork/developer-tools/Apex/3-098787.html

  You can reset the ADMIN password with script apxchpwd.sql

• Creation of a new database Oracle and Sql Developer

  Hello
  
  I am a newbie to Oracle and and a beginner not so Sql Server and Visual Studio.
  
  I am trying to learn Oracle on my local machine. I want to create a new Oracle database and start learning from here.
  
  I downloaded the Client Oracle sql developer and maker of data. Could someone please provide some guidance on how to create an Oracle database?
  
  From the responses, it seems that none of the articles I've mentioned actually creates a database. SQL Server provides a free download, also a developer version for a small fee. What specific Oracle product would be better to provide this type of service?
  
  Thank you
  Mark

  You can download the company for educational use via the OTN site. There is also the Express edition, which includes limits on the OTN site as well.

  Whatever it is, read the agreements to make sure that you use it properly.

  I ran the IdcServer command and the server seems to be generating a log output. I also ran the idcserver_start command and the command idcadmin_start.

  Poth have process IDs. However, I am still unable to connect.

  All the world has never met a problem like that, or know the two fix/debugging better?

• Unable to connect to Oracle Database 11.2 XE Beta

  Hi all:
  
  Try to connect to Oracle Database XE Beta 11.2, the fields are workspace, user name and password. How will I know the workspace.
  
  Thank you

  When you try to open a session?

  If you go to boot (http://127.0.0.1:8080/apex/f? p = 4950), should open the home page of the database.
  Now click the tab "APEX" or red button, connection on request with a user name of database, and you will have the chance to create a workspace Apex.

  See the XE getting started Guide - 6.1 [url http://download.oracle.com/docs/cd/E17781_01/admin.112/e18585/toc.htm]. Getting started with Application Express

  To explore the APEX, the Documentation Library [url http://download.oracle.com/docs/cd/E17556_01/welcome.html] for APEX 4.0 should come in handy.

  Thanking you.

  Error code: ORA-12154: TNS could not resolve service name.

  $ oerr ora 12154
  12154, 00000, "TNS:could not resolve the connect identifier specified"
  // *Cause:  A connection to a database or other service was requested using
  // a connect identifier, and the connect identifier specified could not
  // be resolved into a connect descriptor using one of the naming methods
  // configured. For example, if the type of connect identifier used was a
  // net service name then the net service name could not be found in a
  // naming method repository, or the repository could not be
  // located or reached.
  // *Action:
  //   - If you are using local naming (TNSNAMES.ORA file):
  //      - Make sure that "TNSNAMES" is listed as one of the values of the
  //        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
  //        (SQLNET.ORA)
  //      - Verify that a TNSNAMES.ORA file exists and is in the proper
  //        directory and is accessible.
  //      - Check that the net service name used as the connect identifier
  //        exists in the TNSNAMES.ORA file.
  //      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
  //        file.  Look for unmatched parentheses or stray characters. Errors
  //        in a TNSNAMES.ORA file may make it unusable.
  //   - If you are using directory naming:
  //      - Verify that "LDAP" is listed as one of the values of the
  //        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
  //        (SQLNET.ORA).
  //      - Verify that the LDAP directory server is up and that it is
  //        accessible.
  //      - Verify that the net service name or database name used as the
  //        connect identifier is configured in the directory.
  //      - Verify that the default context being used is correct by
  //        specifying a fully qualified net service name or a full LDAP DN
  //        as the connect identifier
  //   - If you are using easy connect naming:
  //      - Verify that "EZCONNECT" is listed as one of the values of the
  //        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
  //        (SQLNET.ORA).
  //      - Make sure the host, port and service name specified
  //        are correct.
  //      - Try enclosing the connect identifier in quote marks.
  //
  //   See the Oracle Net Services Administrators Guide or the Oracle
  //   operating system specific guide for more information on naming.

  export ORACLE_HOME=/home/oracle/app/product/12.1.0/dbhome_1

  export ORACLE_SID = textdb

  export PATH = $PATH: $ORACLE_HOME/bin

  Please note that you have created a database TESTDB, but in your bashrc file you set the SID as TEXTDB, please fix:

  Please, try the following:

  -Create a new file as initTESTDB.ora instead /home/oracle/app/product/12.1.0/dbhome_1/dbs

  -Have entries

  DB_NAME = TESTDB

  CONTROL_FILES =

  -Save and exit

  Now give it a try.
