SQL Developer 4.0.0.13.80-no-jre.zip

So I want to run SQL Developer on a Solaris 10 x86 platform and i've got JDK 1.7.0_51 installed.
I downloaded the platform agnostic bundle with no JRE, and extracted the zip file. It appears that none of the shell scripts have the correct permissions set (all files are set to 0644) to be executable.
For example the sdcli is meant to be executable,
bash-3.00# zipinfo -l sqldeveloper-4.0.0.13.80-no-jre.zip | grep sdcli
-rw-r--r-- 2.0 unx      586 b-      187 defN 13-Dec-10 13:30 sqldeveloper/sqldeveloper/bin/sdcli
same with the sqldeveloper shell script:
bash-3.00# zipinfo -l sqldeveloper-4.0.0.13.80-no-jre.zip | grep bin\/sqldeveloper
-rw-r--r-- 2.0 unx     3220 b-     1072 defN 13-Dec-10 13:28 sqldeveloper/sqldeveloper/bin/sqldeveloper
and launcher.sh
bash-3.00# zipinfo -l sqldeveloper-4.0.0.13.80-no-jre.zip | grep launcher.sh
-rw-r--r-- 2.0 unx    55308 b-    12596 defN 13-Dec-02 19:08 sqldeveloper/ide/bin/launcher.sh
So despite this, i think i've gotten this into a functional state from a permissions point of view. However now when I start either in GUI mode via Xvnc or with the headless flag, I get the following error:
Maximum number of simultaneous IDE processes exceeded.
I start the SQL Developer GUI, and it launches the netbeans gui, and then the SQL developer banner page jumps to life, to the console that launched the applicat I get the above error, and the Oracle SQL Developer banner just hangs until I kill the PID>
any thoughts?

Hi Ian,
Not sure if there has been any progress, but here is a discussion of this (or at least a similar) issue from a few months back:

Sql developer could not fetch any data while running queries?

I have downloaded SQL Developer , install jdk1.5.0_22 from the website. Then I run sqldeveloper.exe browse the jdk folder. After that i established the connection but it continuously showing loading..No tables No procedures are loaded . what should i do?

Be careful... SQL Developer requires a JDK or the server JRE (which I believe only comes in 64-bit, so go with the JDK if you are on a 32-bit OS).
Prior to 4.0, the SetJavaHome line in your install directory's sqldeveloper.conf (or sqldeveloper-Darwin.conf on the Mac) must be set, but in 4.0 and above that changes to product.conf under your OS's user settings. For Windows 7, that would be in...
C:\Users\<your-userid>\AppData\Roaming\sqldeveloper\1.0.0.0.0\product.conf
Hope this helps. If not, assuming Windows, run sqldeveloper.exe in the bin directory from a command line console so you can see any standard error output in the console, or do a Ctrl-Break to get a full thread dump of what's happening in the JVM.

Java.exe Requirement to run SQL Developer?

Hi all, I'm very new to this so pardon my basic questions. I recently installed Oracle 11g and it came with SQL Developer.
However, when I attempt to start SQL Developer from the Windows Start menu, I get a popup that says cannot find SQLDEVELOPER.BAT.
I have looked around for this file in the Oracle folder in Program Files but did not find it. I did find the sqldeveloper.exe.
When I double click on sqldeveloper.exe I get the following, a dialogue box pop-up that wants the full path name for java.exe.
What do I need to do?
Many thanks, -Nyssa

Hi Nyssa,
Note that the version of SQL Developer that ships with Oracle 11g is rather old. In my opinion, the best approach would be to download the latest production release:
http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html
Choose Windows 32-bit - zip file includes the JDK1.6.0_35 and unzip it into an empty directory. It will run on either 32-bit or 64-bit Windows systems and already contains the correct JDK, so you avoid having to worry about that.

Gary

Engineer to Logical Model in SQL Developer EA4 causes problems

I'm working with SQL Developer 3.0 EA4 (Build MAIN-03.97)
Unfortunately I fond out, that it would be impossible to use the function " Engineer to Logical Model" any more after I change the relational model. In datamodeler.log I got the error message line "[AWT-EventQueue-0] ERROR MDBAction - java.lang.NullPointerException" for each time I use the function "Engineer to Logical Model". I try it out with the sample model "sh_cre_all.sql" and with following steps:
1) Import via DDL File – no problem
2) Engineer to Logical Model – no problem
3) Change some attributes in the relational model – no problem
4) Again Engineer to Logical Model – no problem
5) Save, Exit an Open the sample – no problem
6) Again Step 3 and 4 – no problem
7) Add a table via drag&drop from an oracle schema – no problem
8) Save, Exit an Open the sample – no problem
9) Engineer to Logical Model no longer possible!!!
Bernd

I have experienced similar problems with 'Engineer to Logical model'.
The scenario was following:
Creating Logical model using 'Engineer to Logical model' from existing Relational model.
Modifying the Relational model and 'Engineer to Logical model' again. No exception occured but the Logical model wasn't updated accordingly.
Removing all entities from the Logical model.
Trying to 'Engineer to Logical model' again. No entities were created in the Logical model (even after few tries).
So I got to situation where I was unable to generate a Logical model, which was quite frustrating.
The workaround was to create new Data Modeller project and import to it from the original project - the 'Engineer to Logical model' worked again.

Password change fails in SQL Developer with verify function...

A couple of months ago I enforced a password verify function on our 11.2.0.3 databases and also one legacy 10.2.0.4 database.
At the time I tested on my account (which had elevated privileges...doh!).   Now some users are hitting expiry, they can't change it via SQL Developer.
If I create a user with 'create session' privilege and set their profile to one that uses the verify function (see both below), I then log in to SQL Developer (we have tried with versions 3.1 (Windows) and 3.2 (Linux) with same failure results.
BTW,.. the password verify function enforces the following:
password must be minimum of 8 characters
password must not be the same as the user name, or user name (1-100)
password must contain at least a single digit
password must contain at least a single character
1. Works = I log into the local server and run command line SQLPlus, type 'password' and update.   I can successfully change my password.
2. Fails = I log into the local server and run command line SQLPlus, type 'alter user <me> identified by <newpwd>;' I get:
TEST: SUTEMP > alter user sutemp identified by carport9999;
alter user sutemp identified by carport9999
ERROR at line 1:
ORA-28221: REPLACE not specified
This error is because the account does not have the 'alter user' privilege.   I'm okay with this, as I don't want our users having this privilege.
3. I start SQL Developer 3.2, type 'alter user <me> identified by <newpwd>;' I get the same ORA-28221 error as above.   That is fine, and as expected.
4. Now in SQL Developer, I type 'password', set a valid password, but I get 'Failed to change password' in the Script Output tab.
I have a database 'after servererror on database' trigger set, and querying the database table it is logging into, I see a record with a date stamp matching my failure with a server_error=28221 (the same as above).
So I'm wondering if I'm doing something wrong here, or if this is a bug in SQL Developer.   I don't want standard users having 'alter user' privileges, but I do want to enforce password verification.
I get the same result on three 11.2.0.3 databases (haven't tried any more but suspect same results for others) and one legacy 10.2.0.4 database, and using SQL Developer 3.1 and 3.2.

okay,... I just saw another website which shows I should put in the 'replace <oldpwd>' clause in.
This works in SQL Developer:     alter user sutemp identified by carport999 replace garage999;
So why does the 'password' command fail?     (Developers: it would also be helpful to have the ORA- error displayed as opposed to 'Failed to change password')

SQL Developer can't commit edited data in Table Data pane

When I try to commit changes in "Data" pane for selected table SQL Developer gives me a strange error:
One error saving changes to table "TABLENAME".:
Row XXX: Data got commited in another/same session, cannot update row.
I can see in the log that SQL Developer tries to do something like:
UPDATE "TABLENAME" set "COLUMN"="value1" where ROWNUM="xxxx1" and ROW_SCN=nnn1;
UPDATE "TABLENAME" set "COLUMN"="value2" where ROWNUM="xxxx2" and ROW_SCN=nnn1;
UPDATE "TABLENAME" set "COLUMN"="value3" where ROWNUM="xxxx3" and ROW_SCN=nnn2;
If I update the same rows in SQL window by other condition and do commit - all is OK. Why so strange behaivour?
My table has not a primary key and no other users try to change it. SQL Developer version 3.0.04 and Oracle 10.2.0.4 Linux.
Best regards,
Sergey Logichev

That's because the inaccuracy of ROW_SCN.
I suggest you turn off Preferences - Database - ObjectViewer - Use ORA_ROWSCN (as I did the very moment we got the option).

Top 10 Obstacles to Sql Developer Becoming a World-class Tool

I've been working with Sql Developer day and night for the last 6 months.
On a positive note, the SqlDeveloper team has been the most responsive Oracle product team I've worked with in the 19 years I've been working with Oracle tools. They pay attention to their customers. It's noticed and much appreciated!
I thought I would share the biggest problems that I face with the tool on a daily basis, the kind of problems that make me want to work with a different tool each and every day.
My intent isn't to gripe, it's to focus attention on the biggest productivity drains I face using the tool. Others may have a different list, based on their needs. Without further ado, here is my top 10 problems list:
1) Quality Control.
I cannot count on critical portions of the tool working correctly. This includes an oracle database development tool that is incapable of extracting oracle ddl correctly and which is incapable of correctly displaying information about SQL Server data and database objects. It also includes destroying connection files and losing keyboard settings. When the product was installed, it was incapable of properly displaying code in a worksheet when I scrolled thru the code. The details are listed in other postings of mine.
2) Quality Control.
See #1.
3) Quality Control.
See #1.
4) Very badly done threading.
The tool locks up on a constant basis when it does a many tasks. Rather than let me work on some other task, I have to wait for it to complete. My current work-around is to have two or three sql developer windows open. That sucks life out of my RAM supply, but at least I can get some work done. And, of course, it will often completely lock up and never return, which means I lose all unsaved worksheets. This forum is full of postings about these issues.
5) Memory Leaks / Internal memory corruption.
If I've had the tool open for a few days, or really worked it hard for a day, I will get bizarre compilation errors that make no sense. If I exit the tool, re-enter the tool, and compile the exact same code all will be well.
6) Awkward and slow data entry interface for frequently performed tasks.
Example: I create a new table and want to start defining columns for it. I remove my hands from the keyboard to press the + button, then I have to set focus on the column name field (it should do that for me!). Now that my hands are back on the keyboard, I have to backspace the dummy "column name" value in the column name field (it should ditch that dummy value for me). Only after all that can I actually enter a column name. When I want to add a new column, it's back to the mouse again, for the same drill. The down arrow key should take me to a new column record, as should pressing return at the end of the last field in the column row.
7) Destroys code
Changing a column datatype from varchar2 to nvarchar2 destroys the length of the column. Changing a field on a view destroys the instead of triggers. This is bad. There is no warning that this this is about to happen, which would at least give us a chance to avoid the problem. Better still, of course, would be not destroying that data.
8) Inaccurate checking for record locking.
When I try to edit records in a data grid for a table, I often get an error message telling me the data was modified in another session. It is simply not true. A hand-written update statement in a sql worksheet will work just fine. I've seen posts in the forum discussing this issue. An Oracle database development tool unable to reliably update oracle data tables is embarrassing. See Obstacle #1.
9) Unicode support
Sql Developer is heads above all the other tools I've tried out on this topic.
However, the configuration of the tool to provide unicode support needs to be simplified.
The tool needs to recognize the encoding of the files that are being opened up. On Windows Vista, Notepad seems to infallibly pick the right encoding for the file when I open it. Sql Developer should do the same. Files have specific encodings, the tool should have a default encoding (that I can override). Right now, the tool has a specific encoding and expects all files to match it. Extracting ddl to a worksheet does not respect the encoding choices of the tool, either. It only works with a limited set of tool encoding choices.
10) Resources
Does the sql developer team have the resources they need to compete with vendors like Microsoft? One really big reason for picking sqlserver over oracle is the ease of use of the Microsoft front-end tools. It's not until later that they may realize that Oracle has more capability, but that's still a lost sale.

We are acutely aware of quality and with each release work at improving this. Providing a polished, professional and ultimately user friendly and useful tool is our constant goal.
The broader our customer base grows, the more demands we have. This is a good and exciting position to be in, although it might mean that we need to slow down on our release cycles.
Release 2.0 should address more of the threading and memory leaks displayed as the team have rewritten some of the sections. As for resources, it's true we're a small team and we get on with the work that we do.It might be a little slower than some would like, but I'm not convinced that having large team is necessarily always the answer.
As ever, some of the points mentioned could be added to the Exchange. We'll be reviewing and updating the Exchange again in the New Year.
I think there is another point to add to your list. A lot of what the tool is and will become is from a positive customer interaction we have had to date. While we continue to grow this, I think the product will grow and improve. The forum and all the positive interactions that happen here are key to taking the product forward.
Regards
Sue

SQLPLUS commands in SQL Developer

We are using 11g with Sql Developer. We have some script such as healthcheck etc provided by oracle support, which has SQLPLUS commands in it.
We are not able to run those in SQL Developer. We are getting errors.
Are there any way, we could invoke SQLPLUS shell within SQL Developer?
Thanks in helping.

Hi qwe16235
SQLPLUS command failed - not enough arguments

These are formatting commands we do not do yet.

Unable to connect to a remote db using Sql Developer

hi,
I have 2 systems (A and B) both running on RHEL 6. A has Oracle 10G installed while B has Oracle 11G, and on both I have SQL Developer. A and B are cable networked with static IPs as below.
A 192.168.1.1
B 192.168.1.2
I am trying to connect to database on A from SQL Developer on B. On B, I open SQL developer, enter the connection name, username, password, hostname( or IP) of A, port #, and instance name and hit connect. It shows error about network adapter. I cannot connect.
Listners on both system are active, I can ping each system from each other. No issues with /etc/hosts either.
I am not sure then why it does not work. Would like to know if I can / should be able to connect like above ? What else should I look at to fix?
Shashi

Hello Sir,
Can you telnet to the server on 1521? (telnet A 1521)- failed. with no route error
However, I could telnet B from A without any prob. I then came across a workaround at
TNS-12560: TNS:protocol adapter error
which suggests to :
Go into the Security Level Configuration on your Linux server. In Other Ports, specifically enter <port>:tcp, (example 1521:tcp.
and it worked :)
I am still not sure, why I had to take the workaround route when there was no difference between 2 systems, in terms of route tables, host file entries, sqlnet.ora,listner.ora, etc . I am glad that the issue is resolved and I am able to connect from SQL Developer on A to db on B and other way round, but the the question still remains... :)

I am not able to connect to database in sql developer.how to do?

I downloaded sqldeveloper 1.5.4.59.40. iam not able to establish connection to database. Can anyone tell me ?

Have you created a database (or have one you connect to)?
Have you created the Net Service connections for SQL Developer to use?
Does SQL Developer have access to this Net Serviice name?
Have you created the connections from SQL Developer?
Can you post an error message?

Cannot see table in sql developer or sql plus

I have created a record in application designer. I have then built the table. I can close the record and then find it again in application designer. But if I go to sql plus or sql developer, I cannot see it. Am I missing a step?

You probably can see all the tables of sysadm because someone else give you proper grant for that on existing sysadm's objects.
For the new or modified object (drop+create) you should :
1. connect as sysadm and run
grant select on new_table_name to your_own_user;2. connect with your own user and run
create synonym new_table_name for sysadm.new_table_name;Then you'll be able to query that table without using schema name alias.
Some admin have also a ddl trigger to make it automatically.
You could also work through a role and public synonym if more than one user needs to access sysadm's objects.

Using REF with object table in SQL Developer

When i create object tables and fill them with data, then in SQL Developer de REF value isn't displayed.
I did the following:
CREATE TYPE adres_type AS OBJECT
(straat VARCHAR2(20)
,nummer VARCHAR2(10)
,postcode VARCHAR2(6)
,plaats VARCHAR2(50));
CREATE TABLE adressen of adres_type;
CREATE TYPE locatie_type AS OBJECT
(nr NUMBER
,naam VARCHAR2(20)
,adres REF adres_type);
CREATE TABLE locaties OF locatie_type;
CREATE TABLE locaties OF locatie_type
(SCOPE FOR (adres) IS adressen);
insert into adressen values (adres_type('Arnhemsestraatweg', '33','6881ND','Velp'));
insert into locaties values (1,'Directie', (select ref (a) from adressen a where a.plaats = 'Velp'))
Then in SQL Developer de REF(A) column is empty, while in SQL*Plus it displays the REF value:
In SQL Developer: SELECT a.*, REF(a) FROM adressen a;
STRAAT NUMMER POSTCODE PLAATS REF(A)
Arnhemsestraatweg 33 6881ND Velp
In SQLPLUS: SELECT a.*, REF(a) FROM adressen a;
STRAAT NUMMER POSTCODE PLAATS REF(A)
Arnhemsestraatweg 33 6881ND Velp 0000280209C70341FBB96B4F77813B27B50E53BB4332382E22ADD64AD9B755F651D416B6DA010134
Is this a bug or is there another reason why the ID doesnt display in SQL Developer.
(this didnt work in all the previous SQL Developer releases and still not in de 2.1 E.A. version)

Hi <not sure of your first name>,
I have replicated the issues and logged a bug against this

PL/SQL Developer

Hi, can anyone tell when exactly does a Pl/SQL Developer becomes inevitable in a project?
#Can you explain a real time situation(with respect to a project) when a pl/sql developer plays his role in a project.
#Will the front end for such projects be designed in Java or VB.net? Then how come a developer can interact with the database? When exactly does the need arise for PL/SQl? Like in a banking or financial Sector Application when do we need to interact with the database?(Please explain with a good example)
#Is it the case that the use of SQL and Pl/Sql confined to banking and financial sector applications? Can we use them in any other applications?

Hi,
Hi, can anyone tell when exactly does a Pl/SQL Developer becomes inevitable in a project?In short: Whenever your data is stored/maintained in an Oracle Database.
Will the front end for such projects be designed in Java or VB.net?Could be, but not per sé, however especially (from my personal experience) in the banking/financial sector the front end is an (old/legacy) Oracle Forms application and some overnight monstruous batch processes (slow-by-slow, files) will run. And sometimes that database is an interface to a mainframe that is maintained by sadistically grinning people and have 30 years of undocumented history immediatly available in their mind, and will retire next year, and they know it and we know it ;-)
Nowadays there's APEX as well, a totally different league.
And yes, some JAVA or .NET etc. can be used as well...it just depends.
Like in a banking or financial Sector Application when do we need to interact with the database?(Please explain with a good example)You'd need to interact whenever you need to store or delete data, whenever data changes...
A database MANAGES your data.
A good example?
It doesn't really matter if it's a banking/financial app., it's about the data. Your business.
Perhaps understanding what a database is, will help you, so check the concepts:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/toc.htm
Can we use them in any other applications?Ofcourse you can. Any application you want.
Enclosing:
Your questions are quite broad.
If my attempts to answer seem quite broad as well to you, then please try to express in more detail what puzzles you.
Oracle Database is...a (relational) database (management system), you store/manipulate/extract data in/from/to databases.
SQL and PL/SQL are the main 'interfaces' to facilitate that.
Data = information. Information changes from day to day, every change is a 'transaction'.
Whether your company is a bank or an insurance company or a car rental company, that doesn't really matter.
You need a good and maintainable design to start with, catch business rules, start with the right data model (and don't fall into the 'Hey, let's make it generic-trap' unless you 100% understand what you're doing).
After that, when the application can be built, you'll need a (PL/SQL) Developer.
But a Developer shouldn't stick to (PL/)SQL alone, he should know at least a bit of all other possibilities as well.
And by then you'll realize that from then on you'll be learning every day, and never hesitate to ask questions ;)
