Online Migration using SQL developer

Hi All,
We are planning to migrate our production SQL server.2005 database to oracle 10g. If I use online migration using Oracle SQL Developer Tool to migrate data from SQL server 2005 to Oracle 10g, then will it migrate all those records that are inserted into SQL server 2005 LIVE database after the time when online migration process started?
For example let say the migration process started at 10:00 PM in the night and it found 200,00,000 records in transaction table, it will take 3-4 hours to migrate all of them to oracle, now during this migration time the LIVE SQL server database will still be getting new records, so will 200,00,000 plus newly inserted records will get migrated to Oracle 10g or only those which were initially counted when migration started?
Kindly advise!
Best Regards!

Hi Irfan,
It sounds easy to find that out by a little test. I would expect that only those records will be transferred that are in the remote table at the moment when the migration started. Online data move uses COPY via the JDBC connection, as far as I know.
200,000,000 records and an online data move is a contradiction. From the manual:
Mode: Online causes the table data to be moved by SQL Developer when you have completed the necessary information in the wizard; Offline causes SQL Developer to generate scripts after you have completed the necessary information in the wizard, and you must later run those scripts if you want to move the data. (Online moves are convenient for moving small data sets; offline moves are useful for moving large volumes of data.)
If you are using offline data move, then you are using BCP to unload the data from the SQL Server database, and then the rules of BCP apply how the records are unloaded.
What are you trying to achieve? Do you want to keep the two databases in synch? Then a migration does not seem to me the best way. There are other products, like the Database Gateway for MS SQL Server, or the Golden Gate product.
Best regards

IBM DB2 to Oracle Database Migration Using SQL Developer

Hi,
We are doing migration of the whole database from IBM DB2 8.2 which is running in WINDOWS to Oracle 11g Database in LINUX.
As part of pre-requisites we have installed the Oracle SQL Developer 4.0.1 (4.0.1.14.48) in Linux Server with JDK 1.7. Also Established a connection with Oracle Database.
Questions:
1) How can we enable the Third Party Database Connectivity in SQL Developer?
I have copied the files db2jcc.jar and db2jcc_license_cu.jar from the IBM DB2 (Windows) to Oracle (Linux)
2) Will these JAR files are universal drivers? will these jar files will support in Linux platform?
3) I got a DB2 full privileged schema name "assistdba", Shall i create a new user with the same name "assistdba" in the Oracle Database & grant DBA Privillege? (This is for Repository Creation)
4) We have around 35GB of data in DB2, shall i proceed with ONLINE CAPTURE during the migration?
5) Do you have any approx. estimation of Time to migrate a 35 GB of data?
6) In-case of any issue during the migration activity, shall i get an support from Oracle Team (We have a Valid Support ID)?
7) What are all the necessary Test Cases to confirm the status of VALID Migration?
Request you to share the relevant metalink documents!!!
Kindly guide me in-order to go-ahead with the successful migration.
Thanks in Advance!!!

Hi Klaus,
Continued with the above posts - Now we are doing another database migration from IBM DB2 to Oracle, which is very less of data (Eg: 20 Tables & 22 Indexes).
As like previous database migration, we have done the pre-requirement steps.
DB Using SQL Developer
Created Migration Repository
Connected with the created User in SQL Developer
Captured the Source Database
Converted Captured Model to Oracle
Before Translation Phase we have clicked on the "Proceed Summary"

Problems using Quick Migrate in SQL Developer 1.5 for MySQL to Oracle 10g

Hi all,
I am trying to use SQL Developer 1.5 migration tools (Quick Migrate) to perform online capture and build source model to migrate from MySQL 5.x to Oracle 10g on Windows platform. I get these errors and the Quick Migrate process fails:
oracle.dbtools.metadata.persistence.PersistableObject.doInsert(PersistableObject.java:238)
I did a search and used the sqldeveloper.cmd script but still fails. Then I created a new database and truncated the repository. I now get the above error plus two new ones listed below:
oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
Error loading nls:OALL8 is in an inconsistent state
Error occurred during capture: Protocol violation
It fails during the capture process for MySQL 5.1 database
when it begins to capture the tables from MySQL.
Does anyone know how to resolve these issues when migrating from MySQL to Oracle 10g using Quick Migrate with SQL Developer 1.5 release?
Regards,
Ben Prusinski

Hi all,
I put the following in my sqldeveloper.cmd file:
SET ORACLE_HOME=%CD%
What is very confusing is that with SQL Developer 1.5, there are several levels and several SQL Developer executables! I am really not sure which of these to use:
I created the SQLDeveloper 1.5 directory called SQLDeveloper1_5 on Windows:
1) cd C:\sqldeveloper1_5\sqldeveloper-5338
there exists a sqldeveloper.exe
2) cd c:\sqldeveloper1_5\sqldeveloper-5338\sqldeveloper\sqldeveloper.exe
3) cd c:\sqldeveloper1_5\sqldeveloper-5338\sqldeveloper\sqldeveloer\bin\sqldeveloper.exe
Which SQLDeveloper 1.5 executable should I be using and where should I place the
sqldeveloper.cmd file?
Also I did try to use a different database and schema for the repository with Quick Migrate but it appears a bug exists in SQL Developer 1.5 version that causes errors with Quick Migrate for MySQL to Oracle? Is this correct?
As an update, I ran the following commands:
cd to
c:\sqldeveloper1_5\sqldeveloper-5338\sqldeveloper\sqldeveloper\bin
sqldeveloper.cmd sqldeveloper.exe
Start sqldeveloper.exe
Perform standard capture for MySQL using the new mig2 schema as the new repository
It starts the capture but fails on the errors below:
Error loading nls:OALL8 is in an inconsistent state
UPDATE
============================
I tried this again and it worked with the exception of one error message listed below:
Here are the steps that I followed:
1. Create a Windows cmd script
Put the following entries in the script:
SET ORACLE_HOME=%CD%
save the command windows script as sqldeveloper.cmd
Copy this script to the base installation directory for SQLDeveloper
Example:
1. cd c:\SQLDeveloper1_5\sqldeveloper-5338\sqldeveloper
2. Start SQLDeveloper with the command script that you created earlier
Example:
Open a Windows shell prompt window and execute the following scripts:
a) sqldeveloper.cmd sqldeveloper.exe
b) sqldeveloper.exe
3) In SQL Developer 1.5
From the Migrate menu,
a) Delete current repository and create a new schema in Oracle target database call it mig2.
b) Then create a new repository in SQL Developer 1.5
c) Right mouse click on the MySQL 5.x database and choose capture
It worked with the exception of one error message:
o.jdbc.driver.OracleDriver
Error while registering Oracle JDBC Diagnosability MBean.
So it looks like something is screwed up with my JDBC drivers and configuration for MySQL. How do I diagnose the JDBC driver issue for MySQL?
Thanks!!!

Sorry, we don't support IQ migrations at this time.

Error in Migration Repository using Sql*Developer Migration Workbench

To migrate a MS access mdb database to Oracle using Sql*Developer Migration Workbench, I try to create first the the Migration Repository in SQL*Developer.
The repository is created, but under PACKAGES I could see that package MD_META has been compiled with errors.
PACKAGE BODY AO_PERSONAL.MD_META@DMCAPX (AO_PERSONAL):
Error(27,2): PL/SQL: SQL Statement ignored
Error(30,23): PL/SQL: ORA-00904: : ungültiger Bezeichner
Well, when I ignore this and continue with the next step of the migration process "Capture Microsoft Access Exported XML file" to create the Captured Model, I get the following error message:
ORA-04063: package body "AO_PERSONAL.MD_META" enthält Fehler ORA-06508: PL/SQL: aufgerufene Programmeinheit : "AO_PERSONAL.MD_META" konnte nicht gefunden werden ORA-06512: in "AO_PERSONAL.MD_PROJECTS_TRG", Zeile 3 ORA-04088: Fehler bei der Ausführung von Trigger 'AO_PERSONAL.MD_PROJECTS_TRG'
Target database RDBMS is Oracle Database 10g Enterprise Edition Release 10.2.0.3.0. So the proposal of note 427916.1 to create the Repository in a 10.2 RDBMS does not solve the problem.
I even tried to use the Quick Migrate feature in SQL*Developer, but got the same error message.

"inserted value too large for column"
Is there a LOGON trigger on the database or user ?
I'd be surprised at SQL Developer trying to insert data into anything on connect.
I'd suspect code being executed by the database, maybe using a MODULE or PROGRAM from v$session or USERENV / SYS_CONTEXT.

How do I make a connection to SQL Server Express using SQL Developer 1.5.3?

How do I make a connection to SQL Server Express using SQL Developer 1.5.3, if it's possible at all?
Also, I received a SQL Server dump file of some sort. Is there any way to read this file in SQL Developer and migrate the db to Oracle? Unfortunately I don't have raw DDL and DML for this database--just some sort of a binary dump file from SQL Server.
Thanks.
Dana

Are you using SQL Developer 1.5.3 or 1.5.4?
If using an older version (i.e. 1.5.3), then you'll have to add a DLL to your environment. This is [ntlauth.dll].
If you don't find this DLL in your SQL Developer directory, then obtain the JDBC SQL SERVER Pluggin (jtds-1.2.2-dist.zip) from:
http://sourceforge.net/project/showfiles.php?group_id=33291&package_id=25350
Copy the ntlmauth.dll in the ...\\...\ide\lib directory (no need to register it).
Note: this approach should work if using DQL Developer 1.5.3 and SQL Server Express 2008

M. R.

Can we use SQL developer tool to READ/WRITE BerkeleyDB by any means

We use Berkeley Db as a persistent database, which holds data less frequently changed data. Can is it possible to use SQL Developer tool or any other front end tool that can connect and communicate to Berkeley db file for INSERT, UPDATE, DELETE records.

I assume you're referring to Berkeley DB SQL (BDB SQL API).
SQL Developer is not certified to work with BDB SQL; see the SQL Developer Certifications page.
Something similar was asked some time ago, about connecting JDeveloper to BDB SQL; see this Re: How connect Oracle JDeveloper 11g to Berkeley DB 11g. The SQL tools in JDeveloper and SQL Developer are similar and built on the same components, so my answer there can be extended to SQL Developer as well. While you can probably have SQL Developer properly connect to a BDB SQL database, I am afraid you won't be able to do more than just viewing the data; likely any attempt to generate DDL or DML statements, export data, or run DML statements against the database will fail.
If you migrated to BDB SQL from SQLite and were using a front-end tool for SQLite, it should be possible to use that with BDB SQL as well.

Create statspack report using sql*developer

Hello,
While connecting with PERFSTAT user I can not create statspack report using SQL*Developer:
@?/rdbms/admin/awrrpt
Error starting at line 1 in command:
@?/rdbms/admin/awrrpt
Error report:
Unable to open file: "?/rdbms/admin/awrrpt.sql"
Actually, my problem or question is that how can PERFSTAT user can generate statspack reports from a Client side. What is the other way a non-dba can see the snapshots histroy and generate report (by using perfstat user ) while joing tables or using views?
Thanks a lot.
Best Regards

Hi,
for awr reports @?/rdbms/admin/awrrpt (you need EE+Diagnostic Pack) there is a solution.
Grant execute dbms_workload_repository to <user>;
Grant select_catalog_role to <user>;
get all SNAP_IDs
SELECT   TO_CHAR(s.startup_time,'YYYY.MM.DD HH24:MI:SS') INSTART_FMT,
         di.instance_name INST_NAME,
         di.db_name DB_NAME,
         s.snap_id SNAP_ID,
         TO_CHAR(s.end_interval_time,'YYYY.MM.DD HH24:MI:SS') SNAPDAT,
         s.snap_level LVL
FROM    dba_hist_snapshot s,
         dba_hist_database_instance di
WHERE   di.dbid = s.dbid
         AND di.instance_number = s.instance_number
         AND Di.Startup_Time = S.Startup_Time
ORDER BY snap_id desc;
Select * From Table(Sys.Dbms_Workload_Repository.Awr_Report_Html(DBID, 1, BEGIN_SNAP_ID, END_SNAP_ID));
For statspack i don't know a solutuion. I think the best idea is, create a job to make the statspack report on the server side and access it via external tables or mail them forward to you.

Demonstrating PL/SQL Functions Using SQL Developer

Good afternoon,
I'm starting to write some PL/SQL functions to replace some of the SQL that I use most frequently. A couple of very simple examples would be:
create or replace function func_test (p_1 number) return number
is
x number;
y number;
begin
x :=1;
y :=2;
return p_1 * x * y;
end func_test;
create or replace function func_test2 (p_1 varchar2) return varchar2
is
return_val varchar2(10);
begin
select p_1 into return_val from dual;
return return_val;
end func_test2;
However, at my workplace I haven't been granted create function privileges yet until I can demonstrate some examples, which is understandable.
For the time being, without these privileges, is there a way I can build/test functions in principle locally using SQL Developer without the need to write the functions to our database? I.e. can I demonstrate the above in SQL Developer, but without wrapping in create or replace syntax?
I hope this isn't too vague.
Using Oracle 11gR2 (not logged in to workplace database at the moment for specific version no.)
SQL Developer 3.4
Thanks,
TP

sb92075 02-Nov-2013 19:12 (in response to TinyPenguin)
populating test DB with data is a solvable problem.
You don't need client data to test code (functions).
You only need sample test data; which generally is less than a few dozen records per table.
Absolutely, of course. Our client database is pretty messy though, and includes data prior to the implementation of more recent business rules that I need to take account of. Useful perspective though, thanks.
rp0428 02-Nov-2013 19:14 (in response to TinyPenguin)
Sure, but then I wouldn't have access to all the data in our client database to test functions under various circumstances.
Huh? Why not? It's your database so what keeps you from creating a database link to your client database where all the data is?
Also, I suppose it's not good practice to constantly write/replace/drop functions to/from a database when developing them? Better to test the function in principle and then write to the database?
Huh? Why not? What you think a dev database is for if not for development?
Based on your two posts so far in this thread it's understandable why they don't want to give you privileges yet. Those sample 'functions' you posted are NOT a good use for functions.
In sql developer you can just create and save the queries you use most often. There is no need to create functions for that.
But if you do need an anonymous function now and then just create one using sql*plus syntax:
Our IT department are pretty sensitive about how they allow access, even to the dev environment. As you've identified, I'm not naturally a programmer so the option to play around with the data to develop some representative examples about how we can simplify and devolve SQL reporting to more members of staff is useful to me. I just wrote those two function quickly for the purpose of posting some sample data, which I thought would be helpful. Thanks for illustrating how to return their output using an anonymous block.
FrankKulash 02-Nov-2013 19:13 (in response to TinyPenguin)
Hi,
The obvious solution is to get the privileges. If your employer really wants you to do something, they need to give you the necessary privileges to do it. It's silly for them to tell you to do something, but refuse to let you do it.
Failing that, you can install Oracle on your own machine, as suggested above. It's free and legitimate if you're only using it for learning and developing. Oracle Express Edition is very easy to install.
As a last resort, you can write functions and procedures that are local to an anonymous block, like this:
Thanks Frank. Yeah I'm going to speak with our DBA next week about privileges. I've got XE/SQL Developer installed on my own computer - I wrote those sample functions using them - I just wasn't sure how to call/return anonymous blocks as both you and rp identified to develop at work as an interim solution.
Thanks a lot All,
TP.

Connection ... able to connect using sql developer, but not sqlplus or toad too

Hi folks, having this issue, with only one of my so many databases, what might be the reason and how to fix/correct this, please assist.
Able to connect using sql developer, but not sqlplus or toad too; sqlplus error: ORA-12154: TNS:could not resolve the connect identifier specified
thanks in advance.

SQLDEVELOPER works since it use JDBC Thin & does not use tnsnames.ora
ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 [B]NEVER[/B] involves the listener, the database itself or anything on the DB Server.
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
TNS-03505 is thrown by tnsping & is same error as ORA-12154 thrown by sqlplus or others.
The lookup operation fails because the name provided can [B]NOT[/B] be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.
