• I changed the name of the computer, now I can not connect to Oracle SQL Developer

  Hello my friends!
  
  Everything worked perfectly until I needed to change the name of the computer and now I can no longer connect in Oracle SQL Developer 3.1.
  I restarted Oracle 11 g by stopping and restarting. The order message said stop and start successfully. This tells me Oracle 11 g Express is running, but I can no longer
  connect to Oracle SQL Developer 3.1.
  
  How can I fix?
  
  Thank you all!

  J man,

  I'm not a pro at Oracle XE, but I would say that this is not a problem of SQL * Developer, but the listener of OracleXE.
  Now, I'm in total guessing game mode:
  find the "listener.ora" file in your Oracle installation (from [url http://docs.oracle.com/cd/E17781_01/server.112/e18804/network.htm#ADMQS168] this document is c:\oraclexe\app\oracle\product\11.2.0\server\NETWORK\ADMIN\listener.ora
  I'm sure that it is coded in the old hostname, simply replace it with the new host name.
  Restart your receiver and please try to connect again.

• Unable to connect to host: SQL Developer in Virtualbox:linux:oracle

  Hi all

  Hope this is the right place to ask this question - since his post installation problem.

  I'm very happy because I just installed yesterday manually Oracle Linux 6.5 and Oracle 11 GR 2 on a Virtualbox VM. Ive put the point for a long time but either in the oracle of banks already installed Linux in DBA or home installation of Oracle on windows. But I decided to try something I've been curious for a long time which was to install oracle on linux running in a virtual machine, then usinfg the VM development tools host * developer sql etc...). IM glad that in only 2 days, I was able to make all the measurements required in virtualbox additions for sharedfolders, linux with x, prerequisites for instalation oracle, RPM and Richmond stuff, tune kernel parameters and installation when smoothly managed yesterday

  Today, after the typical small things missing after starting the VM as:

  -lack of vars env; Oracle ADF for path;

  -sqlplus / as sysdba returned instance inactive, so I started OK with SQL > startup

  -also unlocked HR account and under linux has been able to connect to sqlplus h/h

  Now I'm trying to achieve the 2 following things after you start the virtual machine linux/oracle again today:

  1. connect to vm host windows 7 oracle sql developer for my db oracle Linux.

  2 business manager access to the browser in my host of windows 7. Yesterday, just after the installation of oracle finishing I could, just need to open port firewall linux 1158 and https://192.168.1.71:1158 / em Open ok. But today, after that it seems some process to start vm does not work... cause I can't get em either inside the virtual machine, nor my host locally.

  Some info of linux from my installation:

  $ echo $SHELL

  / bin/bash

  $ set | grep ORACLE

  ORACLE_HOME=/U01/app/Oracle/product/11.2.0/dbhome_1

  ORACLE_SID = orcl

  and im getting the error when I click on the Test button:

  Please let me know what orders/information you need to help me. Im sure im close to after so many steps to learn how to install and able to do the installation of oracle on linux in a virtualbox im really looking forward to complete this exercise, thank you very much for your help.

  See you soon,.

  Your listener is the list on "localhost" (127.0.0.1 ip address) that the universal loopback address.  No request to this address never let the customer request.  Your virtual computer must have a fixed IP address, and the listener must be listening on this fixed IP address

• Problem connecting to Oracle SQL Developer

  Hi all
  
  I am trying to connect to the database from the remote computer through Oracle SQL Developer, it gives me the following error.
  
  Status: Faliure-Test failed: connection/o: the network adapter could not establish the connection.
  
  I had given the host name as the name assigned to this server, it did not work.
  
  Later, I tried with the IP address of the server, it worked.
  
  Can someone tell me how I can connect by giving the hostname instead of IP address.
  
  Thanks in advance,

  Hi Vinay,

  One way would be to add an entry in your hosts file. On windoze, you can find it in

  Hello

  It is probably part of a larger battery error (if you can download the zipped file of complete log we can see if something is visible).

  This is a new installation or and upgrade or displacement of FMS? What version do you use?

  Have you tried to stop the foglight server, make sure that the DB is down too and then restart?

  There are articles describing errors as part of a larger pile of errors.

  This article KB https://support.quest.com/SolutionDetail.aspx?id=SOL64412 talks to ip in the hosts file is not wrong

  Other articles describing similar problems:

  There is an article describing a bug that has been fixed at https://support.quest.com/SolutionDetail.aspx?id=SOL63134

  Another speaks of a problem with the Storage Manager service https://support.quest.com/SolutionDetail.aspx?id=SOL73892

  With the attached log file we can see more information, I recommend also the opening of a case of pension because they can help solve the problem in a more interactive way.

  I hope this helps.

• How to connect container with SQL developer

  Hi all

  This is probably a trivial question-, but I'm not able to find the answer. I use sqlplus most of the time, so I am not familiar with SQL developer.

  I have 12 c and container named ORACONTAINER, in this container, I HR schema.

  When I do connect via sqlplus ("sqlplus hr/hr@ORACONTAINER') - it works well, and"sqlplus HR/HR"will not work - and that's ok.

  With SQL developer I can connect as sys, but when I try h/h it gives me name of username/password invalid - because I do not know where to specify the user HR container.

  Thank you

• Connect the JSK & Sql developer

  Hello

  Someone trying to connect JSK SQL Developer? I tried to do by using the credentials of DB that I could see in server.xml but without success.

  Thank you!

  Usually the HSQLDB JSK uses works in memory mode, not in Server mode - see "Server Modes" at http://hsqldb.org/doc/guide/running-chapt.html. This means that it is not possible to use a tool like SQL Developer, TOAD, squirrel etc to connect in it. You can manually write a script so that it starts the DB in Server mode, you will need to change the jdbc connection string in server.xml in an appropriate manner. Then you should be able to use an external tool to reach the DB using the same jdbc connection string.

  If you just need to make a simple few queries then you can try the query tool that comes with HSQLDB. It is very basic, but has the advantage that you need not change the DB mode, it can connect to a DB in memory of a JSK running. To run it, find the hsqldb.jar in JSK and run:

  Java - cp hsqldb.jar org.hsqldb.util.DatabaseManagerSwing

• How to create a new connection on oracle sql developer

  Hello
  I was installed oracle sql program in windows after installation I tried to create a new connection, but I get the error message: the account is locked.

• Connection problem with SQL Developer 3.0.0.4

  I have a strange problem with SQL Developer (SD) 3.0.0.4. So that the implementation of a new connection I have in double entries listed for some of the databases listed in my TNSNAMES.ora file. When I try to connect to one of the databases has entered duplicated, I get the following Oracle error:

  ORA-01034: Oracle not available ORA-27101: Kingdom does not exist SVR4 shared memory error: 2: no files or directory

  however, if I try to connect to the same database using SQL * more or TOAD, it works perfectly and TOAD has no duplicates.
  
  At first, I thought maybe that SD has been reading multiple copies of the TNSNAMES.ora so I checked and removed all the duplicate files and set the variable of environment TNS_ADMIN to point to that and the single instance of the TNSNAMES.ora file. Yet once, SQLPlus and TOAD to work fine, but SD is always showing entries twice and always have reported the above error when I try to connect to a database with a duplicate entry. I should mention, I'm able to connect to the database that have only a single entry listed use SD.
  
  If I understand correctly, SD uses JDBC as underlying connection mechanism. Based on this "agreement" I thought that maybe I had a file corrupted in the Java Cache, so I cleared the cache, but I always get errors.
  
  As mentioned, I use SQL Developer 3.0.0.4 with Java 1.6.0_11 (included in the download). In addition, I have installed JRE 1.6.0_24 and I am running Windows XP SP3. Any ideas or suggestions are greatly appreciated.
  
  Craig...

  Hi Craig,.

  Or, if I have misunderstood completely the scenario you describe, here's a post on the forum about duplicate entries appear in the drop-down list Alias network when the connection Type is TNS:

  Developer SQL 2.1.0.63 TNS name in characters of the connection

  This solution involves clean a bad TNSNAMES. ORA file with double score entries to test the death of SID.

  I understand that you're a novice. Please get into the habit to avoid root, unless your really don't need.

  Oracle and the root mix well.

  And my oracle database is only available for the 'Oracle' user. Currently, if I try to start with the user oracle sqldeveloper it throws exception. but its ok with root.

  Probably the permissions and other things. See note above. Perhaps a lack of "root.sh" after installation.

• SQL Developer oak leaf after logout

  Hello

  I use the new SQL Developer for a few weeks now.

  It's very well in most ways. But one thing is really bad.

  After disconnecting a connection saved the SQL Developer automatically opens again a worksheet and reconnects the connection that I have just closed.

  It happens to almost any connection.

  Also, if I have a worksheet to a session previously opened disconnectet, after striking in this worksheet the automactly Developer opens again the connection.

  What is a standard behavior? Could I change any setting to refuse to reconnect automatically?

  Thanks for any advice.

• Is there a real BENEFIT in SQL * Developer Automated Unit Testing?

  I'm trying to understand the unit test in SQL * Developer. Asked me to evaluate it as a method of test automation on an integration solution that we develop.

  (1) my 'A' schema has this table:

  SQL > DESC EMP

  Name                                      Null?    Type

  ----------------------------------------- -------- --------------------

  EMPID NOT NULL NUMBER

  EMPNAME VARCHAR2 (30)

  SALARY NUMBER (7.2)

  COMM_PCT NUMBER (2.2)

  Table (2). has these values:

  SQL > SELECT * from emps;

  EMPID EMPNAME SALARY COMM_PCT

  ---------- ---------- ---------- ----------

  1 ROHAN 10000.05

  2 JOHN 20000

  3 PETER.06

  4 SMITH

  (3.) I create this procedure in drive A:

  create or replace

  PROCEDURE award_bonus (NUMBER, sales_amt NUMBER p_empid)

  AS

  REAL Commission;

  comm_missing EXCEPTION;

  BEGIN

  SELECT comm_pct IN the commission OF EMP

  WHERE empid = p_empid;

  IF the commission IS NULL THEN

  RAISE comm_missing;

  ON THE OTHER

  PGE UPDATED

  SET salary = salary + sales_amt * commission

  WHERE empid = p_empid;

  END IF;

  END award_bonus;

  (4) now, I want to create a unit test in SQL Developer to test this procedure.

  (5) I created a user "unit_test_repos" according to the instructions in the tutorial.

  (6) ' SELECT OPERATION': I specifies the procedure of award_bonus.

  (7) ' SPECIFY the name of test': give a name and select "create with a single model.

  (8.) 'SPECIFY the STARTUP': Add a ' copy Table or the line "the startup process.

  -I give "EMP" as the source table.

  -And then I get this for the 'generated query.

  SELECT ROWID AS SRC$ ROWID, s.* FROM EMP s

  -Target table has "TMP$ AWARD_BONUS.

  (Q1) WHAT IS THE PURPOSE OF CREATING ANOTHER TABLE?

  (Q2) WHEN THE TEST IS DONE, ARE ROWS OF PGE copied into this table?

  (Q3) Why is this? Why can't the test simply read 'EMP '?

  (9) "PARAMETERS SPECIFY": I give "Input".

  -1 for P_EMPID

  -10000 for SALES_AMT

  -In "Expected result", I say "success."

  (Q4) So I should know in my mind the results of the proc, foregoing given entries?

  (10) ' SPECIFY VALIDATION': I add validation "poll rows of queries.

  -I paste the following query: SELECT count (*) FROM EMP WHERE empid = 1 AND salary = 10500

  -that is, I know that for an amount of 10000 sales, employee 1 will get a Commission of 10000*.05 = 500. For example, 10000 (its sal) + 500 = 10500.

  (Q5) The thought that the above is correct?

  (11) "TEARDOOWN SPECIFY": give nothing.

  (12) my unit test is created.

  (13.) I run now by clicking on the button of the beetle, to the left of the green arrow. Unit test is run.

  (14) now in my table a.emps, 1 salary has increased to 10 500, and the diag test case, I get the "execution results: SUCCEED.

  (15) now, I run the unit test again.

  (16.) salary 'EMP' table emp 1 is passed to 11000 (which is correct) and the so-called execution results "SUCCESS".

  (Q6)  My question is: the query I gave for validation, SELECT count (*) FROM EMP WHERE empid = 1 AND = 10500 salary, now gives 0. so, this means that no row is returned for this condition and so the test must FAIL. But how is SQL * Developer said that the test was SUCCESSFUL. How does this system of validation?

  (17.) I went through the tutorial, but I do not understand these concepts >

  (Q7) What is the purpose of disassembly? I undersand the option 'drop table' "disassembly", where you drop the temporary table, but I do not understand the others, 'Table or line restore' and 'code pl/sql user '?

  (Q8) WHAT IS the advantage of making the test like this? Can I use an Excel spreadsheet and make dozens of unit tests faster than this method?  It is easy to understand too. This method is complicated.

  Your answers and your advice would be greatly appreciated.

  The temporary table to hold the original values for EMP. After the test runs, you must configure the disassembly to reset the return values of the temporary for the next time table that the test works again, he has values of expected start.
