SQL Developer vs TOAD: connection stability

I am trying to persuade a group of developers to switch from TOAD to SQL Developer. The feature set of version 1.5 is quite nice; and most of our users don't need the extra bells and whistles of TOAD. However, in side-by-side situations, it seems that TOAD gets better response times. In particular, the connection for SQL Developer sometimes seems to freeze and then come back later, while TOAD does not seem to be affected.
Our DBA thinks that the difference may be from SQL Developer using a JDBC connection while TOAD uses Oracle SQLNET. He said that switching to an LDAP server for name resolution might make the difference; but we really don't have much experience at this level of detail on the connections.
Is anyone else having a similar issue? Has anyone been able to 'equalize' the performance of the two products?
You insights are welcome.

Developer using a JDBC connection ... I think the problem ist not SQL Developer\JDBC itself but rather the Java Runtime Environment. The behavior you describe sounds like that Garbage Collector hits you. SUN trys to make the GC better in each Java version, so I suggest you update your JRE to the newest one you can get(today: 1.6.0_06 from java.sun.com).
After doing that, install "Oracle SQL Developer for Windows, with JDK already installed" to make sure that SQL Dev. use the new one. You can check the used java version within SQL Dev. at the "About" dialog (register: version)
If you are familiar with java you should play with some gc and memory settings. Details about that you find here: http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html

  • SQL Developer and TOAD connection.

    Hi,
    I am able to see the DDL script for tables using TOAD, but NOT using SQL Developer (2.1.1). Same user, pass, and tnsname file.
    They use same tnsname.ora file on my computer. I set basic and TNS connection for SQL Developer.
    The connection is from my computer to the server (Oracle 11.1.0.7 EE).
    ORA-31603: object "ALARM_DEFINITION" of type TABLE not found in schema "AIRCOM"
    ORA-06512: at "SYS.DBMS_SYS_ERROR", line 105
    ORA-06512: at "SYS.DBMS_METADATA", line 3241
    ORA-06512: at "SYS.DBMS_METADATA", line 4812
    ORA-06512: at line 1
    It is same with packages. I cannot see package body.
    What is the different and which additional privileges I need to see the DDL script?
    Thanks in advance for your help!

    I don't think it's a connection issue. There seem to be differences in how Oracle and Toad access system views to show objects. If you search the boards you see it has effected a couple of people. Sometimes they post what permissions they changed to get things to work for them.
    ie... Re: Issue with viewing Package Body  in SQL Developer 2.1 RC1
    I don't think I've seen any official documentation to indicate what privileges need to be granted in order to see them thought. And I think there is a bug that prevents generating DDL for tables owned by other users. I don't know if that extends to generating stored procedure code.

  • Install Oracle XE, SQL Developer, and Toad on the same machine?

    I have been trying to install Oracle SQL Developer, Toad, and Oracle Express on my work computer. Installing SQL Developer and Toad was pretty straightforward, and I was able to browse the XE database with SQL Developer. But after installing Toad, problems started. Toad was using Oracle XE's registry settings to locate ORACLE_HOME and oci.dll. So I tried changing the settings for Oracle XE in the registry. Toad now works, but not Oracle XE. And while I was going through this all, I even had a time when I had Toad and oracle xe working, but not SQL Developer. It almost looks like you can choose two of the products, but not all three.
    So, my question to the community at large is "Can it be done?". In what directories do you have each product installed? What environment variables do you have set? Where is your tnsnames.ora? What Oracle registry settings do you have set (namely HKLM\SOFTWARE\Wow6432Node\ORACLE\KEY_XE)?
    I can post my current settings, but I've been through so many iterations that these current settings don't really matter that much.
    Here are the details I am looking for
    Path to sqldeveloper.exe
    Path to oracle.exe (for Oracle XE)
    Environment Variables
    ORACLE_HOME
    ORACLE_BASE
    TNS_ADMIN
    PATH (just the oracle stuff)
    Registry Settings
    HKLM\SOFTWARE\Wow6432Node\ORACLE\KEY_XE\ORACLE_HOME
    HKLM\SOFTWARE\Wow6432Node\ORACLE\KEY_XE\ORACLE_BASE
    HKLM\SOFTWARE\Wow6432Node\ORACLE\KEY_XE\TNS_ADMIN
    HKLM\SOFTWARE\Wow6432Node\ORACLE\KEY_XE\OLEDB
    HKLM\SOFTWARE\Wow6432Node\ORACLE\KEY_XE\ORAMTS_CP_TRACE_DIR

    I don't use toad, but there should be no reason why you can't install all 3. SQL Developer is a very clean install and affects nothing else. It doesn't add to the path, or create any registry entries except for file associations.
    A toad installation should pick up your oracle client (in this case the XE code). I am curious as to why you felt you had to change registry settings. What problem were you trying to fix?
    My recommendation would be to uninstall everything, clean the registry and reinstall in the order XE, Toad, SQL Developer. Test in between installations and seek help for problems as you find them. Bear in mind that this is the forum for SQL Developer. QUestions about Oracle XE would be better answered in the dedicated forum, or in the Installation forum, and questions about Toad in a toad forum.

  • SQL Developer 1.5 Connection Problems

    Unable to connect to my localhost installation of Oracle 11G in Windows XP environment
    SQLPLUS connections look just fine.
    I went out to the windows registry to verify the Oracle SID.
    The environment ORADLE_SID is set to 'orcl'
    I have tried logging in as HR and as SYS. Both work in SQLPLUS. Neither work in Sql Developer.
    The connection settings I am using are as follows:

    Really appreciate your assistance.
    Thanks,

    Kent,
    Does Oracle monitor this? Yup - I am PM for SQL Developer and various team members, like Turloch, also monitor the forum.
    We use thin or thick JDBC drivers to connect to the Oracle Database from SQL Developer, Turloch was trying alternatives. You should be able to connect using the thin JDBC driver, not using tns. (Basic Connection)
    When you try the Basic connection, please can you ensure that the Preference (Tools -> Preferences -> Database- Advanced Parameters) "use OCI/Thick driver" is not selected.
    Instead of localhost, can you insert the IP address of your machine?
    I have one other question - when you installed SQl Developer 1.5, did you install it into a new empty directory?
    Finally, if you have a support contract for the Database, you can contact Metalink and open a SR. There you should be able to track your progress and they can help you get connected.

  • SQL Developer vs TOAD - query performance question

    Somebody made me notice same queries are executing slower in SQL Developer than in TOAD. I'm rather curious about this issue, since I understand Java is "slow" but I can't find any other thread about this point. I don't use TOAD, so I can't compare...
    Can this be related to the amount of data being returned by the query ? What could be the other reasons of SQL Dev running slower with an identical query ?
    Thanks,
    Attila

    It also occurs to me that TOAD always uses the equivalent of the JDBC "thick" driver. SQL Developer can use either the "thin" driver or the "thick" driver, but connections are usually configured with the "thin" driver, since you need an Oracle client to use the "thick" driver.
    The difference is that "thin" drivers are written entirely in Java, but "thick" drivers are written with only a little Java that calls the native executable (hence you need an Oracle client) to do most of the work. Theoretically, a thick driver is faster because the object code doesn't need to be interpreted by the JVM. However, I've heard that the difference in performance is not that large. The only way to know for sure is to configure a connection in SQL Developer to use the thick driver, and see if it is faster (I'd use a stop-watch).
    Someone correct me if I'm wrong, but I think that if you use "TNS" as your connection type, SQL Developer will use the thick driver, while the default, "Basic" connection type uses the thin driver. Otherwise, you're going to have to use the "Advanced" connection type and type in the Custom JDBC URL for the thick driver.

  • Sql developer won't connect with SQL server database on cluster

    Hello,
    I have a microsoft SQL server database on a windows cluster. Name for this cluster is like XXX/YYY
    When I try to connect to this database with SQL developer, I get a failure, mentioning:
    "Status : Failure -Cannot connect to Miscrosoft SQL Server on XXX/YYY"
    As far as I know, I have installed the correct jtds driver (version 1.2.5), since I can connect to sql server databases on single server hosts.
    Does anyone know how to connect to databases on windows clusters?

  • SQL Developer 3.2 - Connection reset

    Hi, I've installed SQL Developer 3.2 build MAIN-09.30 under Windows 7 64 bit and Client 11g 64 bit.
    Wherever server I try to connect, when I click on a table I have the connection reset and it tries to fetch data with no success, i.e. the Results display show with the gauge moving and nothing more, while in backgroup I have a message box that suggets to reset the connection. If I stop task and choose some other thing, such as data, I can see tha data inside the table. Getting back to Columns, I have to click on refresh button but I don't see anything.
    More, I have the following errors:

    Hi,
    The case you describe is not familiar to me, but you may want to review this thread with a similar error:
    java.sql.SQLRecoverableException Io exception Size Data Unit (SDU) mismatch
    The comment there about a "recent JDBC driver upgrade to ojdbc6.jar" is interesting. I encountered a different error within the past couple weeks (can't recall exactly what), but noticed that the ojdbc6 jar files in 64-bit SQL Developer 3.2.09 and Instant Client's do not match. The SQL Developer jar is newer. Copying the one from the Instant Client (11.2.0.3) and replacing the SQL Developer version (supposedly 11.2.0.3 also) fixed whatever issue I faced. Comparing the manifest.mf files shows this:
    ojdbc6.jar from SQLDeveloper 3.2.09.23 64-bit -> Repository-Id: JAVAVM_11.2.0.3.0_LINUX.X64_110829
    ojdbc6.jar from Instant Client 11.2.0.3   64-bit  -> Repository-Id: JAVAVM_11.2.0.4.0_LINUX_120621This is just my best guess at this point.
    Let us know if this helps,

  • SQL Developer Hangs when connecting for Remote Debug

    Hello,
    I've been trying to use the Remote Debug feature of SQL Developer. We are writing a Web Application that connects to Oracle and I would like to debug a package function on the database server (which is not the same machine as my SQL Developer client).
    To test my configuration, I tried connecting on SQLPlus creating a connection (by calling exec dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', 'xxxxx'); ) and calling a function which had a breakpoint and the debugging started immediately on SQL Developer. Then I tried putting the dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', 'xxxxx'); call inside the stored procedure I was debugging (prior to the line with the breakpoint) and it connected and got to the breakpoint successfully as well. So I'm pretty sure my firewall / user privileges are set up correctly.
    So I modified the function that my web application eventually calls to create the connection (in order to remain in the same session) but whenever it gets to the connect_tcp line SQL Developer hangs and I'm unable to debug. I've realized that it only hangs if I have a breakpoint there. If I don't have a breakpoint then it creates a connection just fine. Of course without a breakpoint it's a bit difficult to debug isn't it? :)
    My Sql Developer version is 3.0 and I'm connecting to Oracle 11.1.0 Below you can find a dump when running SqlDeveloper with console. My OS is windows XP and my Oracle instance is running on Linux.
    I appreciate any help you can provide.

    What I mean is that I put the connect_tcp command inside the package function I want to debug in order to ensure it's going to remain in the same session. e.g.:
    Function GetValue Return Varchar2 Is
    Begin
    dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', '25255');
    return 'My Value';
    End;
    I'm afraid I cannot post our code which causes this problem due to our information security policies and simple console and web applications failed to replicate the problem. The function creates a connection to Oracle SQL Developer (which can be seen in the environment with the small ladybug icon) if no breakpoints are set which obviously doesn't allow breaking into the function. However if a breakpoint is also specified in the Return line the connection seems to freeze Oracle SQL Developer. No ladybug icon is shown and no Remote Debug Session seems to open.

  • Sql developer won't connect to internet to check for updates

    Hi all,
    When I try to check the latest updates, Sql Developer (2.1.0.63) says it can't access to Internet in order to search for updates.
    The credentials that I gave are correct (proxy, port, username, password) : when I click on the "Test Proxy" button, it says everything is OK.
    But when I click on the "OK" button, it won't connect.
    Then I click on the "Cancel" button, and check the details and get the following stack trace:
    org.xml.sax.SAXParseException: <Line 6, Column 39>: XML-20125: (Fatal Error) Attribute value should start with quote.

  • SQL developer cannot see connection info from tnsnames.ora file

    Greetings All,
    I have been using sql developer for a while. Currently on 3.0.04.34.
    I have 16 database connections.
    Everything was working fine until yesterday.
    Today when I tried to connect to a database from the list of connections I am getting following error:
    Invalid connection information specified. Verify url format for specified driver.
    When I pull up the property for this connection -connection type is still TNS, Netwrok Alias is now greyed out and what was in Netwrok Alias has shifted to Connect Identifier.
    When I try to create a new connection I do not see entry from tnsnames.ora file for the databse I am trying to connect to in the Network Alias drop down list.
    I can connect to this database from sqlplus.
    Has anyone seen this behavior? Does any one know the fix for this?
    Thanks.

    Hi,
    Maybe your preference settings got corrupted, or the Tnsnames.ora file got moved to somewhere SQL Developer can't find it.
    Are you using either:
    1. Tools|Preferences|Database|Advanced|Tnsnames Directory, or a
    2. TNS_ADMIN environment variable
    to point to your Tnsnames? Having one of those should enable the Network Alias drop-down list to get populated. Otherwise, if the values moved to Connection Identifier are correct, then you won't be to connect in that mode without also having an Oracle client installed with an 11.1 JDBC thick driver (ocijdbc11.dll).
    If there is no issue with the Tnsnames. ora location, it might be a good idea to use Export Connections to make a backup of your connections. Then you can try deleting the connections from SQL Developer and re-importing them. Even if that doesn't fix the problem, you should be no worse off.
    Regards,
    Gary

  • Missing SQL Developer functions when connecting to MS SQL Server 2005

    Hi all,
    I've connected SQL Developer to a ms sql server db. Now I can't use the functions from SQL Developer like
    - Drag&Drop tables to the sql-sheet,
    - autocompletition of attributes (Strg+Space).
    Is this function not supported or do I have to change some preferences?
    THX Steve

    Unfortunately most of the advanced functions of SQL Developer are supported only for oracle databases, so on ms sql, or almost anything else you can do little more than browse data.

  • SQL Developer Error when connecting to Listener on Glassfish

    I am having some issues with connecting to Apex Listener via SQL Developer. I get "cannot connect to connection" when I attempt to connect.
    I do get apex pages (when I use the Glassfish default port - it doesn't seem to take the specified port which is defined as 7788 in the apex.properties at the config.dir location).
    I have defined the user via the war config (which is written to the credentials file), and added the users under default config > file realm in Glassfish.
    I wonder if anyone has had a similar issue?
    I am using the following:
    Glassfish 3.1.2.2
    Apex Listener 2.0.2.133.14.50

The port specified in apex.properties is only used by Standalone Mode, the port that GlassFish uses is configured by GlassFish, not Listener.
    I have defined the user via the war config (which is written to the credentials file), and added the users under default config > file realm in Glassfish.You only need to do the former, doing the latter should have no effect, I would remove the user in the GlassFish file realm, to avoid causing confusion.
    I wonder if anyone has had a similar issue?
    Ensure you have spelt the role name correctly when setting up the user, any typos (it is case sensitive) and it won't match the role, and will therefore refuse access.
    You have disabled SSL verfication as well? (If you are not using SSL)
    http://docs.oracle.com/cd/E37099_01/doc/doc.20/e25066/install.htm#CHDJFAAI
    If neither of those work, try turning on logging in the Listener to see if the request is even reaching Listener (It sounds like it's not even connecting TBH).

  • SQL-developer 4 EA - connections becomes invisible

    When leaving my SQL-developer open over nigth, my connections become invisible. The connections are still open and available but unfortunately invisible.
    I have to re-start SQL-developer in order to fix this annoying problem.
    I don't know the exact reason for this, Maybee a shutdown of a database or something else.
    regards Karsten

    I'm experiencing the same issue as KarstenH-dk -- connection window is blank... try to close, reopen window, connections don't reappear -- have to close EA4 and restart EA4 for them to show back up

  • Sql developer impossible to connect to  the server MSS at localhost

    hi,
    plz help i can't connect to sql server 2008 via SQL Developer i want to migrate a database with online migrate.
    thank's

    The 'connection refused' error probably means that TCP/IP connections haven't been enabled for the MSSQL server.
    However, SQL Developer doesn't work with the microsoft driver, you must use jtds.
    To find out why the connection tab isn't appearing try running sqldeveloper from <sqldev>\sqldeveloper\bin\sqldeveloper.exe. This will open a console which may show useful information.
    Remember you need to select the JAR file, not the directory.
