Oracle Toplink Optimization

Can anybody help me with Toplink Query Optimization?
I want to print the query that Toplink generates for an existing code. Is there any method I can use?
Expression Emp= builder.get("employee").get("employeeID").notIn(
new String[] { "1", "2" });
System.out.println("Query from the builder employee.employeeID" + builder.getStatement());
This returns null.
The above is just a part of the query. I am very new to this and I need to optimize this query. It is now taking anywhere from 25 to 30 sec's. I am hoping if I can print the query that it is generating then I can use it to optimize the query.

Note that there is a relatively active TopLink forum on OTN
TopLink/JPA
The folks over there are likely to have substantially more insight into the particulars of what TopLink is doing.

  • Anything fixed in Oracle TopLink 11g Release 1 (11.1.1.1.0) ?

    Was there anything fixed in Oracle TopLink 11g Release 1 (11.1.1.1.0) ?
    I don't see anything in release notes ( http://www.oracle.com/technology/products/ias/toplink/doc/11110/relnotes/toplink-relnotes.html ) regarding fixes. Anybody know where I can get that info? We have run into a couple of issues in the previous 11g release (11.1.1.0.1) and want to know if those issues have been addressed in the new release.
    Thanks!

    The two major areas of work in 11gR1 (11.1.1.1.0) are enhancements to EclipseLink included with the its 1.1.1 release as well as enhancements around TopLink Grid (JPA-Coherence integration).
    The EclipseLink 1.1.1 fixes are documented here: http://wiki.eclipse.org/EclipseLink/Release/1.1.1

  • Migration path from 10.1.3.3.0 to Oracle TopLink 11g: Technical Preview 2 ?

    What is needed to migrate from 10.1.3.3.0 to Oracle TopLink 11g Preview 2?
    Does using Java 5 and swapping the Jar files are enough?
    Can I use as is all the configurations generated by TopLink Workbench 10.1.3.3.0?
    What is working in 10.1.3.3.0 that is not yet or will not be working in Oracle TopLink 11g?

    If you open the project in the 11g preview it will automatically update the metadata and generate the deployment XML in the new format. Alternatively you should be able to open the 10.1.3.3 metadata in the 11g preview's runtime.
    The biggest issue you may encounter in the upgrade besides replacing the libraries and ensuring you are using JDK5 is the removal of the code deprecated in previous releases.

    I found an error in ORACLE TOPLINK while adding table CUSTOMER, MOTHERBOARD and MEMORY from database to workbench. Any idea how to solve that error?
    And other questions:
    1. Does Toplink support inheritance and aggregation object table modelling? If it doesn't, what should I do?
    2. Is there any example or tutorial using Toplink Foundation Library?
    Thanks a lot.

    What error do you get in the MW?
    TopLink does support object-relational data-types, but the Mapping Workbench does not have support for object-relational data-types, so you may need to define your mappings through the TopLink Descriptor and Mapping Java code API. There is a section on object-relational data-type mappings in the TopLink User Guide.

  • Migration from conventional Oracle Toplink to Opensource..

    I heard about EclipseLink release coming in next month.
    I would like to know whether the Open-source toplink is available now.. Our company is using Oracle Toplink 10.1.3.3.. We are using Oracle's paid version of Toplink called Enterprise..As we are hearing about Oracle toplink going to opensource, We would like to switch to Opensource Toplink.. How would be the migration impacts? Could any one plz answer my question..

    EclipseLink's home page is at,
    http://www.eclipselink.org
    You can download the latest milestone from there, and get access to the status and documentation on the Wiki.
    The API is the same, but the package names are different. You can run the Package Renamer to migrate your code to the new packages (long time TopLink users should be familiar with this :) ).

  • Exception [TOPLINK-46] (OracleAS TopLink - 10g (9.0.4) (Build 031126))

    Hi,
    I am using TopLink for simple Department-Employee relation, i have my project xml configured, But i am facing the problem with following exception
    Descriptor Exceptions:
    Exception [TOPLINK-46] (OracleAS TopLink - 10g (9.0.4) (Build 031126)): oracle.toplink.exceptions.DescriptorException

    Runtime Exceptions:
    What could be the reason?
    Thanks
    Madhu

    My best guess would be that you have a 1:1 mapping from Employee to Department. This mapping represents part of the primary key.
    Make sure that your 1:1 mapping is not configured as read-only. Another issue is that you may have set the relationship as target foreign key. This has the same effect as read-only and is not applicable in the 1:1 returning from a 1:M.

  • Replacing Oracle Toplink with TopLink Essentials

    Is it possible to force OC4J to use TopLink Essentials by default
    instead of Oracle TopLink?

    Hi
    Replace your toplink jars in your server with the new
    jars. it should pick up automatically
    Regards,
    RaghavendraHi,
    I am trying to use the latest version of Toplink Essentials with the embedded OC4J in JDeveloper 10.1.3.
    Can you please be more specific?
    Which JAR files must be replaced?

  • How to verify OC4J uses Oracle Toplink 10.x and not Toplink Essentials

    Hi,
    We dont want to use the default JPA provider "Toplink *Essentials*" that comes with OC4J. Rather we want to use Oracle Toplink 10.x
    I downloaded [Oracle Toplink 10.x|http://www.oracle.com/technology/software/products/ias/htdocs/1013topsoft.html] and followed the installation instructions:- http://www.oracle.com/technology/products/ias/toplink/doc/10131/install/install.html#CHDBBIFB
    When i deploy my EJB 3.0 appliation and invoke a JPA Entity, i can see the server log:- NOTIFICATION TopLink, version: Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))
    Do i have to do any other configuration/setting to ensure that i use Oracle Toplink and not Toplink Essentials in OC4J?
    Thanks in Advance,

    rashant,
    Hi, there are currently the following providers to choose from - you may want to consult your rep for any details on moving from 10.1.3.4 to 10.1.3.5.
    1) TopLink or EclipseLink using EclipseLink JPA - the RI for JPA for WebLogic, OC4J and GlassFish
    - EclipseLink JPA is focus of all current JPA development as part of EclipseLink and TopLink
    2) Another open-source JPA implementation like OpenJPA or Hibernate
    Deprecated:
    3) TopLink using TopLink JPA - replaced by (1) TopLink using EclipseLink JPA
    4) TopLink using TopLink Essentials JPA - replaced by (1) TopLink using EclipseLink JPA

  • Sources for package oracle.toplink.internal.expressions in version 10.1.3.5

    Hi there,
    I just downloaded file toplink_101350.zip from Oracle and in folder \toplink\jlib it has a file called toplink-src.zip. When I look at jar file toplink.jar it contains much more packages like oracle.toplink.internal.expressions that in the source file.
    Now where can I get the full oracle toplink source?
    Thanks.

    Hi,
    the web appears to be full of such error messages and some point to the use of named native query vs. named query. So here are some options for you to try
    1. Create a test project in 11g using the same tables and compare the generated code with yours to see a difference
    2. Get a 10.1.3.5 project that you haven't migrated and pass it on to customer support for them to have a try on this.
    +"If this is not resolved, we can not chose Jdeveloper as a future IDE at the company..."+ Actually it doesn't appear to be a JDeveloper issue but a TopLink / EclipseLink issue. Abandoning JDeveloper is like shooting the messenger. Just so you know.

    At the point 'Map the Java Classes: Create One-to-One Mappings' (http://www.oracle.com/technology/products/ias/toplink/doc/10131/main/_tutorial/index.htm) I'm not able to select a table reference because there is no one available.
    As result i get the following message after generating 'Mapping Status Report':
    TopLink Map 'tut01Map' -> One of the packages is incomplete.
    Package example.model -> One of the descriptors in this package is incomplete.
    Descriptor Employee -> Some mappings are incomplete.
    Mapping address -> No table reference is selected.
    Mapping address -> Table reference is invalid because of the target table chosen.
    Mapping version -> Mapping references write lock field stored in cache, but is not read-only.
    Mapping phoneNumbers -> No table reference is selected.
    Mapping phoneNumbers -> Table reference is invalid because of the target table chosen.
    Descriptor PhoneNumber -> Some mappings are incomplete.
    Descriptor PhoneNumber -> The following primary key fields are unmapped: EMP_ID
    Descriptor PhoneNumber -> The following primary key fields have no writable mappings: EMP_ID
    Mapping owner -> No table reference is selected.
    Mapping owner -> Table reference is invalid because of the target table chosen.
    End TopLink Map 'tut01Map'
    Did I make a mistake or is there a wrong configuration? Please help.
    I'm using:
    JDeveloper 10.1.3.2.0
    MySQL 5.0.33 with Connector/J 5.0.5
    Windows XP
    Thanks, TGau

    Update

    Yes I did. But my database storage engine is set to MyISAM which don't support foreign keys. So this 'error' results from database configuration (Info: InnoDB do support foreign keys).
    I'm wondering why the queries didn't throw any errors. So the foreign key/reference part was just skipped.
    Thank you very much, rsapir.
    PS:
    How can I configure configure 'application side' references/associations? It is described in the TopLink Developers Guide on site 34-10 ... but I have no Add/New Buttons?

    Hello,
    Without more information, I can't determine what the problem is. This exception's english wording is "Object comparisons can only use the equal() or notEqual() operators. Other comparisons must be done through query keys or direct attribute level comparisons.", and implies that the query expression is using a Like operator where atleast one side of the comparison is an entity instead of a string value. Entity/object comparisons are only supported with the equal or notEqual comparisons.
    Best Regards,
    Chris

    MySQL is one of the primary databases that TopLink supports.
    TopLink supports any SQL database with a valid JDBC driver, and has built-in extensions for many databases.
    See,
    http://wiki.eclipse.org/EclipseLink/FAQ/JPA#What_databases_are_supported.3F
    EclipseLink's primary test database is MySQL.
