SQL Server 7 to Oracle 10g

When I try to migrate from SQL Server I get all of the objects to migrate into the repository. But when I move the objects over to Oracle it seems to cycle through the tables several times, each time moving slower and slower. Then it finally hangs.
What am I doing wrong? Is this normal, and I am just using it in the wrong method? Please help!

Hello James,
Do you see anything unusual in the Errors.log file? If thats ok, will you be able to supply me your log file?
Possible reasons for slow performance:
* Is the Oracle repository running at good speed?
* Is the machine on which the omwb is runing, have the minimum spec as mentioned in the readme docs?
Regarding product hang: Although, we cant say the reason until we see the log, is it possible that you are using a different JDK other than jdk 1.4.2_04?
Please do send along the Log file.
Thank you.

Migration from MS SQL Server to Oracle 10g

Hi,
In our application, we are planning to refresh data every one hour from MS SQL Server to Oracle 10g. Can anyone tell me what approach can be followed?
Thanks & Regards,

Hello,
migrations can be done with the Migration Workbench that is included in the SQL Developer: http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
But your question sounds more like a replication of data than a migration. Please read as a starter the following note in My Oracle Support (former Metalink):
Note 283700.1: How to replicate Data between Oracle and a Foreign Datasource
That note describes ways for the replication in both directions. Please let me know whether this is helpful for you.

One way replication from MS sql server to Oracle 10g

Hi,
We are using Sql server 2005 windows 2003 32 bit and Oracle 10g 10.2.0.3 on linux 64 bit
Is it possible to replcate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit?
If yes then what are the steps.
It will be one way replication from sql server to oracle.
Which option is best sql server dts or Oracle Stream replication to replicate table data?
Regards,

If you want to push data from SqlServer, then ODBC, Linked tables, DTS etc.
If you want to pull data from Oracle, then Heterogenous Services / Gateway.

Migration from SQL server to Oracle 10g

Hi, I am new here,
I would like to ask how to use SQL developer MWB to migration SQL Server to Oracle?
I have go through the doc(s) like: getting start, user's guild, etc. and have following problems
(1), where should the SQL developer installed? in SQL Server side? Oracle side? or any PC with connection to the databases?
(2), do I need to get some plug-in(s) for MWB to work? If yes, which plug-in do I need and where are they?
Thank you very much.

Faster way to migrate data from SQL Server to Oracle 10g

We have to migrate data from SQL Server to Oracle 10 g.
One particular table on SQL Server has records around 1.25 millions.
We tried moving data using DTS package, but looks it will take hours with current speed of 300 records/minute.
This table has TEXT column, which has XML strings stored. I am not sure, if this is the reason for slow migration.
Would you please suggest better options to migrate it faster?
Thanks in advance !!!

Have you tried Migration work bench?

Linking to SQL Server from Oracle 10g on 64bit Linux

I have this working, so I thought I would post my steps.
In versions 8 to 10 of Oracle, the software for making these connections was known as Heterogeneous Services. It was 32bit only software and the actual binary file that was executed when querying a non oracle database was $ORACLE_HOME/bin/hsodbc. When a query was made to the linked database, a process was started on the machine with the name of hsodbcXXX (where XXX is the name of the DSN).
In version 11g of Oracle this software is now referred to as Database Gateways and there is a 64bit version as well as a 32bit version. The binary file that is executed in this case is $ORACLE_HOME/bin/dg4odbc.
Fortunately the 64bit Database Gateway software can also be used with Oracle 10g databases as long as it is up to version 10.2.03 and has the odbc compatibility patch installed. (5965763).
To make use of this, we need to install the 11g ODBC Gateway into a separate ORACLE_HOME and start a listener from that environment. We can then make use of that listener from the 10g environment.
So here is what I did to get this working: (Note: DSN = MyDSN)
1.     Download and install 64bit ODBC driver with support for 64-bit ULEN from Easysoft. The file is named odbc-sqlserver-1.1.4-linux-x86-64-ul64.tar. You'll need to email Easysoft support for the URL. Create the DSN entry as part of the install. At the end of the process it can test the DSN. The query should come back with info about the SQL Server. Test the connection using isql from the /opt/easysoft/unixODBC/bin directory to verify that it works as well (/opt/easysoft/unixODBC/bin/isql –v MyDSN). Note, I installed easysoft driver under /opt rather than the /usr/local which is the default. /usr/local/easysoft is a symlink to /opt/easysoft.
2.     Install ODBC gateway via the 11g Gateways installer. You can do a custom install and deselect all but the ODBC Gateway component. (http://download.oracle.com/otn/linux/oracle11g/linux.x64_11gR1_gateways.zip)
3.     Create a /home/oracle/11g_environment.sh script that sets 11g ORACLE_HOME, PATH, and LD_LIBRARY_PATH variables. It should look something like this:
#set ORACLE ENV vars for 11g
ORACLE_HOME=/u01/app/oracle/product/11.1.0/tg_1 # (assuming that is where ODBC Gateway was installed)
PATH=/bin:/usr/bin:/u01/app/oracle/product/11.1.0/tg_1/bin:/opt/easysoft/bin:/opt/easysoft/unixODBC/bin
LD_LIBRARY_PATH=/opt/easysoft/lib:/opt/easysoft/unixODBC/lib:/u01/app/oracle/product/11.1.0/tg_1/lib
export ORACLE_HOME
export PATH
export LD_LIBRARY_PATH
4.     Create $ORACLE_HOME/hs/admin/initMyDSN.ora, $ORACLE_HOME/network/admin/listener.ora, and $ORACLE_HOME/network/admin/tnsnames.ora under 11g structure. They are as follows:
initMyDSN.ora:
# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.
# HS init parameters
HS_FDS_CONNECT_INFO=MyDSN
HS_FDS_TRACE_LEVEL=0
HS_FDS_TRACE_FILE_NAME=MyDSN.trc
HS_FDS_SHAREABLE_NAME=/opt/easysoft/unixODBC/lib/libodbc.so
HS_FDS_SUPPORT_STATISTICS=FALSE
# ODBC specific environment variables
#set ODBCINI=/etc/odbc.ini
#set ODBCINSTINI=/etc/odbcinst.ini
#set LD_LIBRARY_PATH=/opt/easysoft/lib:/opt/easysoft/unixODBC/lib:/u01/app/oracle/product/11.1.0/lib
#set PATH=$PATH:/opt/easysoft/unixODBC/bin:/opt/easysoft/bin/
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
listener.ora
MyDSN =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
SID_LIST_MyDSN =
(SID_LIST =
(SID_DESC=
(SID_NAME=MyDSN)
(ORACLE_HOME = /u01/app/oracle/product/11.1.0/tg_1)
(PROGRAM=dg4odbc)
(ENVS=LD_LIBRARY_PATH=/opt/easysoft/lib:/opt/easysoft/unixODBC/lib:/u01/app/oracle/product/11.1.0/tg_1/lib)
tnsnames.ora
# tnsnames.ora Network Configuration File:
# Generated by Oracle configuration tools.
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
MyDSN =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST=localhost)(PORT=1522))
(CONNECT_DATA=(SID=MyDSN))
(HS=OK)
5.     Add another entry for MyDSN in /u01/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora so tnsping works in 10g environment as well.
MyDSN =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST=localhost)(PORT=1522))
(CONNECT_DATA=(SID=MyDSN))
(HS=OK)
*** Notice that the MyDSN listener runs on a different port (1522) as it is a separate listener.
6.     Login to machine as user oracle and source the 11g environment script. “source ~/11g_environment.sh”. Now start the listener. “cd $ORACLE_HOME/bin”. “./lsnrctl start MyDSN”.
7.     Login to a new shell as user oracle with a 10g environment.
8.     Run sqlplus and create the database link. “CREATE PUBLIC DATABASE LINK SQLSERVER connect to “<someuser>” IDENTIFIED BY “<somepass>” USING ‘MyDSN’;”
9.     test the link. “select * from information_schema.tables@SQLSERVER;”
If it is successfull, you should see a system process named "dg4odbcMyDSN".

So what have you found out for yourself so far (considering the solution to this is easily found on the web)?
Have you looked up Heterogeneous Services?

Reading milliseconds from Sql server into oracle 10g

Hi,
We have a very time sensitive pressing requirements to be addressed immediately.
We need to read the date time column from sql server 2008 into oracle 10g.
We have a dblink established between the two servers and have tried to use sql server and sql native client 10 driver to read the dates from sql into oracle.This we are able to do very successfully.
The issue is in reading milliseconds stored in sql server.The millisecond part comes in as 00000 from sqlserver to oracle.These milliseconds are needed to identlfy the unique records.
For instance
SQL SERVER Oracle
source_id source id
01/01/2012 6:30:35:456 01/01/2012 6:30:35:000000.
Im issuing my query through Toad via Oracle to remote sql server using a dblink which connects using HS ODBC connection to sql server 2008(remote).
We have no control over sql server Db as this is remote third party DB.We just have select access to their tables to bring into our own oracle DB.
Any insight or help will be much appreciated.

Hi,
Could you please send the following information -
- what version of HSODBC are you using ? Is it a 10.2 version ?
- what is the SQL*Server datatype of the column you are reading ?
- from Oracle could you issue -
describe sql_server_table@hsodbc
- what is the Oracle datatype shown for the column ?
Could you also run your tests using SQLPLUS instead of TOAD ? We don't support TOAD and need to know if the problem also happens when using SQLPLUS, to avoid it being a TOAD problem.
Also, 10.2 HSODBC is now desupported and you should be using the 11g Database Gateway for ODBC (DG4ODBC) which is a direct replacement for HSODBC. To use DG4ODBC your RDBMS needs to be at 10.2.0.4 or higher and DG4ODBC should be installed in a completely separate ORACLE_HOME from the existing 10.2 install.

Mike

No suitable driver when connect MS SQL server from Oracle 10g using JTDS

Hi,
I have developed a java servlet application connection to MS SQL using jtds-1.2.jar. I have try to deploy this application to Oracle 9ias and it works fine.
However, when I deploy the same application to Oracle 10g (10.1.2.0.2), I encounter this error - java.sql.SQLException: No suitable driver.
I have copy the jtds-1.2.jar to Ora10g/jdbc/lib, Ora10g/j2ee/home/lib and also the Ora10g/j233/OC$J_GENERAL/applications/sampleApp/sampleApp/WEB-INF/lib folder, and also setup the data source via the EM interface. The data-source.xml entry is as follows:
<data-source location="jdbc/ess" class="com.evermind.sql.DriverManagerDataSource" xa-location="jdbc/xa/essS" ejb-location="jdbc/ess" connection-driver="net.sourceforge.jtds.jdbc.Driver" username="scott" url="jdbc:jtds:sqlserver://202.xx.xx.xx:1433/sampleDB" inactivity-timeout="30" name="ess"/>
</data-sources>
Is there any configuration that I've forgotten to set?

Which I believe from what you have entered is:
Ora10g/j2ee/OC4J_GENERAL/applib
There's a general JDBC 3rd party driver set of documentation here:
http://download.oracle.com/docs/cd/B14099_11/web.1012/b14012/datasrc.htm#sthref592
This is not using jtds-1.2.jar but it shows how another set of 3rd party jdbc libs are used with the server.

From SQL Server to Oracle 10g

Hi!!
My IT staff have been using SQL Server for quite a time and we have set up all our procedures under this platform, for example, our initial concern in this phase of the migration is: Under SQL Server we use templates that we use to import data into our tables in SQL Server DB, after uploading that data, we run some stored procedures and finally a view.
Is there any thing similar to a template under Oracle 10g?
I have been reading about the tools that 10g offers for data upload/download, but what about data files that doesn't have any field separator? All my fields have the same number of characters, that's why I use templates to import data on SQL Server.
Any ideas?
Best Regards,
M Guirao

How to import from sql server to oracle 10g

Hi,
I have given some file with no extention and the client told me that
it has two tables in it emp and dept. which he extracted from sql server.
Now I have the file with me.
I have a local oracle database .
Is it poosible to load that file into the oracle 10g database.
If possible please send me the details. If not please tell me the details reqd to do the things.
Thanks in Advance

Well, what format is the file in? If it is a text file you should be able to use SQL*Loader.
Can you view the file using (for example) Wordpad?
Or from the command line (ie in a DOS box) just say
TYPE myfileThen post the format for a few lines here, between and (use square brackets instead of curly)

Load Data from SQL Server to Oracle 10g using Sql*loader utility

I am trying to lod data from sql server 2005 to oracle 10g.
What is the best way to do it?
Can sql*loader utility do it?
what is the difference of using sql*loader utility and migration tool fom sql developer ?
Thanks
Edited by: user11313758 on Sep 30, 2009 4:30 PM

Hello:
You could consider using Oracle Heterogeneous Services to do this. If your Oracle database is on a Windows platform the link below shows you how to make a connection to SqlServer from an Oracle database.

Migrate Data action hanging migrating from sql server to Oracle 10g

Hi,
I am currently migrating a SQL Server 2005 db to Oracle 10g using SQL Developer 1.2.1. I have created the migration repository, captured the SQL Server db objects, and created the target schema. There are about 109 tables captured. During Data migration, however, the data move hangs. I have run the data move a couple of times now and it does not hang while migrating any particular table, but seems to be more to do with the length of time it is taking to migrate. Could this be an issue with SQL Server connections being lost? The SQL Server db is quite large. Row counts of 100k plus.

Probably. There is an offline option for migrating data under the migration menu. Generate Scripts for the data move using the appropriate converted model and u can export the data to bcp export files and load it with teh generated SQL Loader scripts.

Dual contection between SQL Server and Oracle 10g

Hi.
I have the following scenario:
- a MS SQL Server database with some data i'd like to tranfer to an Oracle XE or SE database.
- The idea would be to start a process (possibly on the SQL Server DB) to gather and transform certain data and then, connect to an Oracle Db an insert the data.
I'm good working with Oracle Forms, and i know i can connect to an MS SQL Server using odbc (forms 6i). So obviously, my first choice would be using forms6i to create some text files (using text_io) as a temporary storage and later connect to Oracle DB read and process text files. Another option which i'm not familiar in 6i would be using the EXEC_SQL package.
Apart from this solution, i wonder whether it's possible to create a stored procedure somewhere and have it execute from a deamon or something. This of course depends on the possibility of establish a dual connection between the two DBs.
Thanks in advance ...!

Luis,
The documentation for Generic Connectivity is here:
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14232/gencon.htm#sthref343
But it is pretty confusing. There is a nice easy and complete example here: http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:4406709207206#18830681837358
It shows a connection to MS Excel, but connecting to SQL Server is the same - just use a different ODBC driver.

Migrating users in sql server to oracle 10g

migrating users from sqlserver to oracle10g
what are the setps to follow for migrating users in sqlserver to oracle10g
also
please let me know the migration of roles and privelage in sqlserver into oracle10g
meaning
these are roles in sqlserver
public
db_owner
db_accessadmin
db_securityadmin
db_ddladmin
db_backupoperator
db_datareader
db_datawriter
db_denydatareader
db_denydatawriter
what are equivalent role and priv in oracle

Hi,
We can't directly and exactly map the roles but I have mapped to similar roles below.
In Oracle, the access mechanisms work like this:
A user with create table privilege can create any number of tables in his own schema. He may have some quota on tablespaces, the amount of data he can use for all his tables together in that tablespace and he becomes the dbowner for his schema and schema objects.
He can grant select, insert, update and delete privileges to any user he like.. the user who got the privileges is called a "grantee". A grantee can again grant the privileges that he received to others, provided he has been granted with "with grant option".
A pseudo user called public, is only a place holder to say ALL ... if you grant some privileges to PUBLIC, then everyone in the database will have that privileges.
A user with EXP_FULL_DATABASE will be able to backup the full database.
Please refer to oracle documentation for complete details.
public - PUBLIC
db_owner - SCHEMA USER him self
db_accessadmin - SCHEMA USER himself
db_securityadmin - SCHEMA USER himself
db_ddladmin - SCHEMA USER himself
db_backupoperator - a role EXP_FULL_DATABASE
db_datareader - any user who has select previliges
db_datawriter - any user who has select, insert , update and insert privileges
db_denydatareader - any user who do NOT have select priviliges
db_denydatawriter - any user who do NOT have insert , update and delete privileges
