SQL Developer 1.5.3: SIZE honored in SET SERVEROUTPUT ON SIZE nbr ?

I'm running some PL/SQL in SQL Developer 1.5.3 and am getting some buffer overflow error messages while using dbms_output.put_line.
At the top of my script, I've put:
set serveroutput on size 100000
But get these errors:
ORA-20000: ORU-10027: buffer overflow, limit of 20000 bytes
ORA-06512: at "SYS.DBMS_OUTPUT", line 35
ORA-06512: at "SYS.DBMS_OUTPUT", line 198
ORA-06512: at "SYS.DBMS_OUTPUT", line 139
ORA-06512: at line 28
Does SQL Developer 1.5.3 not, in fact, honor the SIZE portion of SET SERVEROUTPUT ON? If not, can this be set in the preferences? (couldn't find it).
Thanks.

Note... I'm running Oracle 9i, soon to be 10g. Don't know if that matters. Seems in 11g, there's another way to set the buffer size specifically for dbms_output, e.g. dbms_output.enable(100000)-- or null for unlimited. I couldn't get this to work on 9i.
Danadbms_output.enable(buffer_size) has been available since 9i if not before.

The DBMS_OUTPUT tab is one of the tabs you'll see when opening a SQL Worksheet. If you take a look at the "Useful Features of SQL Developer" demo under the "Podcasts and Viewlets" link, you'll see the set of tabs below the SQL Worksheet. They include the Results and Script output tabs and the DBMS_OUTPUT tab.

Hi All,

Thank u.

there is no relation between them

Viewing Chinese Characters / Encoding setting in SQL Developer

Hi all,
I am new to SQL Developer 1.1. I have just downloaded the tool yesterday.
I have a table where there "should" be chinese characters in a NVARCHAR2 column. But I see only inverted question marks when displaying that data in SQL Developer.
I know from a ressource on the web, that SQL Developer is able to display chinese characters ( see http://awads.net/wp/2006/07/06/sql-developer-and-utf8/ ).
The NLS_NCHAR_CHARACTERSET is set to AL16UTF16; the NLS_CHARACTER_SET is set to WE8ISO8859P1.
The encoding under Tools->Preferences->Environment is set to "Cp1252".
What is actually the influence of this Encoding setting and do I have to make changes to that to view the data?
In addition I have to admit, that we actually do not really know if the data entered the DB correctly, that is as chinese characters. Maybe there have occured conversion errors that were made in a application that writes the data into the database. Actually I want to verify that. So, if I have the right settings configured which should be fine to see chinese characters and then I see only inverted question marks I can conclude that the data actually entered the database corrupted and the error is not an display issue with SQL Developer but rather an error in the application that writes the data to the database.
Thanks to any answers in advance!
Regards,
Philipp Hinnah

Prompt For User Input in SQL Developer

I am using the '&' in a very basic SQL select script, but I do not get a prompt for my input. However, i have used the '&' in update scripts and it does prompt me.
For example:
select DCC_DESCRIPTION
from S_TBLDTMINOR
where DCC_DTMINOR = &Minor;
Gives an ORA-01008 error (not all variables bound).
If it's a varchar field and I use '&Minor' - it executes with no error, but does not prompt for data. Please note: this script works when it's run in SQL*Plus, but not in SQL Developer.
If I execute:
update S_TBLDTMINOR
set DCC_DESCRIPTION = 'Mark & Wilson'
where DCC_DTMINOR = 'AAA';
It does prompt me for a value (but I do not want it to).
So I know prompting works in SQL Developer, but it does not work in select statements.
Is this a configuration setting I can change in SQL Developer? I know I can use the escape in the update statement to avoid the prompt, but I'm not concerned with that. I'm trying to get the prompting to work in the select statement.

Hi user12289057,
1/Not sure what your testcase is (including table definition), I was trying to reproduce with:
select * from dual where dummy = '&myin'
2/Try
undefine Minor
to ensure Minor is not already set.
3/Minor may need to be quoted if it is a string.

Problem in launching newly installed SQL Developer in Linux

In order to install ORacle SQL Developer for linux, I tried to install JDK 5.0 according to the instruction. I downloaded the files and installed it. But when running the sqldeveloper, I got the error message:
Error: This product requires a Java(TM) Platform 5.0 runtime.
You are using 1.4.2 from /usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre
Yes, in directory /usr/lib/jvm, there are:
java-1.4.2-gcj-1.4.2.0, jre, jre-1.4.2, jre-1.4.2-gcj, jre-gcj
But rpm -qa|grep jdk returned:
jdk-1.5.0_10-fcs
How can I resolve this issue?

you are running SQL Developer using gcc's runtime environment.
just set JAVA_HOME to the dir where jdk1.5 is installed, then PATH=$JAVA_HOME/bin:$PATH, and it should work.

Feedback deferred constraint is incorrect in sql developer 2.1.0.63.41

In the earlier 2.1.0.63 the set contraint didnt work entirely in sql developer.
In this new release the set constraint can be executed and it works, however when you violate a constraint there is no feed back.
example:
I create the following table and insert 2 rows
CREATE TABLE d_orafout
( code NUMBER CONSTRAINT d_codepk PRIMARY KEY DEFERRABLE,
message VARCHAR2(50))
INSERT INTO d_orafout VALUES(904,'invalid table name')
INSERT INTO d_orafout VALUES(903,'invalid column name')
Then i execute:
set constraint d_codepk deferred;
set succeeded.
Then an update that violates the primary key:
update d_orafout set code = 903 where message = 'invalid table name';
1 rows updated
Then when i commit i should get the following error (which works fine in SQL*Plus):
ORA-02091: transaction rolled back
ORA-00001: unique constraint (NWG806.D_CODEPK) violated
However the commit gives me the following output:
commit;
commited
The transaction is not commited, it is rolledback but i dont get the error i need.

Hi <please supply your name>,
Thanks for this feedback,
I have replicated this issues and I have logged a bug.

SQL Developer - Memory Usage

We have SQL Developer installed on our Citrix farm and we are facing hard times right now. Unfortunately SQL Developer is consuming in some cases more than 650 MB/session. And since we have on each site more than 50 users in same time, server gets exceeded very fast. Currently server is running Windows 2003 R2 edition x86. We know that this is bad and we are planning on switching on Windows Server 2008 R2. And here comes my questions:
Will Windows Server 2008 R2 work more effectively with Java x64 and SQL Developer x64 and resolve our memory issues?
Thank you.

Hi,
I have no idea if Windows Server 2008 runs Java applications better than 2003 but, regardless of which you run, here are a couple of ideas that may be of help:
1. x32 Java/SQL Developer starts up with a smaller working set (246,000 KB) than x64 Java/SQL Developer (318,000 KB).
2. Try tweaking the garbage collection algorithm, using Garbage-First:
Re: Memory Leak or Bad Java Garbage Collector
I ran across this (old) comment from a blog on blogs.msdn.com:
Even though Windows Server 2008 R2 is exclusively a 64-bit operating system, 32-bit applications are
supported by enabling the WoW64 optional feature. If this feature is not enabled and you try to run a
32-bit application, the application will fail to execute. The WoW64 execution layer is an optional component
that is installed by default on R2 releases after beta1. You can save resources by removing the feature if
you are not going to be running 32-bit applications on your Server Core install. Regards,
Gary

Import an excel file into SQL Developer and create a table

Hello everyone!
I have an Excel file I want to Import into SQL Developer. Do I need to Create a table first than import the file into the table?
Or is there a way to import an Excel file and it automatically generate or turn into a table?
I would really appreciate any directions or explanations.
Thanks everyone!

Joyce Scapicchio
SQLDeveloper TeamThanks for the reply but the problem was I needed to convert the file to a csv format. To do this open the file in Excel and re-save as CSV Comma Delimiter. Don't worry about data-types because when the file is uploaded to SQL Developer, you will have the chance to set all the parameters, data-types and so on.
Once I did this and try opening the file, the setup window opened and I was able to do all the additional tweaking and convert the data to a table.
Because of this I am speculating that SQL Developer does not work with Excel XLSX extension.
Thanks again!

Setting up OID/LDAP with SQL Developer?

I have over 100 databases to add to SQL Developer. I use OID and would like to allowd SQL Developer use that. How do I set it up? Parameter file somewhere?

I have installed SQL Developer on my laptop (windows XP pro), and we have LDAP server and other database servers on unix. I have done following and is working for me using OID/LDAP 9.2.0.7.
TO use OID based name resolution,
copy ojdbc14.jar from ORACLE_HOME(10.x) /jdbc/lib (windows client)
to /<SQL Developer home>/jdev/lib/patches
Hope this helps.

Set Serveroutput On throught PL/Sql

Hi All,
In order to display output through DBMS_output.put_line one need to do set serveroutput on, I want to do that through PL/SQL as application I work on user forget to do so. I want to come over that. Although its useful sometimes as application supports both ways even if for some condition I don't want to display output and same code can be used for displaying output.Any suggestions
thanks

How is the application executing the pl/sql with the dbms_out statement in it?
Either the sqlplus script that contains the code should have a set serveroutput on size nnnn right before the pl/sql code is executed OR
the application should read the dbms_output buffer using the dbms_output.get_line procedure and use its own functionality to display the output. In this case you enable the buffer using dbms_output.enable and when done dbms_output.disable. We have done this in pro*c programs.

Set indention / tab size in Oracle SQL Developer

I've been poking around for an hour. Can't figure this out.
Where, either on the app's UI or in the "product-preferences.xml" file, can I change SQL Developer's indention (tab) size to 3? My organization uses PowerBuilder, and when I copy+paste our PB SQL (which uses leading tabs) into Oracle SQL Developer, it looks like crap. It would really help if I could change the code editor to a tab size equivalent to three spaces.
And no, we can’t use spaces. :-)
Thanks!
(maybe SQL Developer 2 could have a tab size field in “Preferences”)

In 1.5.x, it's under Preferences - Database - SQL Formatter - Alignment and Indentation .
However, at least in the current 1.5.3, a bug ignores the tab preferences completely, so you're stuck with the 2 spaces. If you can't wait until this gets fixed (with luck in the upcoming 1.5.4 or else maybe by 2.0), revert to an earlier version.

Tablespace allocated size in Oracle SQL developer

Hello,
Currently in my oracle 11g database, there are two datafiles under the users tablespace. Today during one application installation, I ran into this error msg:
ORA-01654: unable to extend index BSANITY.SI_CUID_I7 by 8 in tablespace USERSSo i checked the tablespace status in SQL developer and saw that the USERS tablespace is at 99% used. Datafile #1 is full at max size 32G and #2 is full at max size 4G. So I decided to change dbf #2 maxsize to 32G, I used the following command:
alter database datafile '<file path here>' autoextend on maxsize 32000M;I checked the dba_data_files view and verified the maxbytes change.
However, when I check the tablespace status in SQL developer, it is still showing USERS tablespace as 99% used. I'm wondering is there anything else I need to do after altering the datafile maxsize so that the change gets reflected in SQL developer?
Thank you in advance!

SQL Developer:Problem with multi byte size after import using excel format

Hi,
Need your help. I am trying to export multibyte characters from our China instance(r11i instance) using SQL Developer's export data via Excel format into an R12 Vision instance. I have a staging table with exactly the same structure in both instances. Prior to export to excel, I check the byte size of the sample data below using LENGTH and LENGTHB sql functions and these are the results:
Sample data = 材料LI（USD）
LENGTH=9
LENGTHB=13
Then, I exported the table as excel file. Afterwards, I used SQL Developer to import the excel file into the table of the target instance. I check the bytesize again and here are the results:
Sample data = 材料LI（USD）
LENGTH=9
LENGTHB=17
The byte size increased from 13 to 17. I did not change anything on the excel file. Just straight forward export to excel file then imported it to the target instance. How come there is an increase in byte size? Has anyone encountered this in SQL Developer? We really need to export the files as excel.

Wendell,
This forum is for handling issues migrating from non-Oracle databases to Oracle databases.
As this is an Oracle to Oracle issue using SQL*Developer export it would be better to open a new thread in the SQL*Developer forum -
SQL Developer
There will be more people there who can help with this problem.

Mike
