SQL*Plus with Oracle 10g Express Edition

How Can I do to log in using SQL*Plus into Oracle 10g?
My Schema is: Banco.Global
My Password is: 111111
I need to write SET SERVEROUTPUT ON to get answer?
I opened the Prompt, but i don't know to log in.
Thanks and my english is not as well as you.

If i write:
SQL>connect "Banco.Global"/111111
a error message is raised: Invalid username/password; logon denied
but if I log in into Home Page with the same Username and Password, I get to log in.
There is difference to connect SQL*Plus and the connect with Home Page the Oracle?
I need to connect with SQL*Plus, because i need to make a test.

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,
Faizal MK

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.

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

(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?

Loading data by sql loader in oracle 10g on linux

I am trying to load data in Oracle 10g on linux by using sql loader, but getting error
Problem in log showing that field length of SURNAME field is more than table field size.
Following is the error in log file of sql loader
Record 21: Rejected - Error on table TABLE1, column
SURNAME.
ORA-12899: value too large for column SURNAME (actual: 65, maximum: 64)
and it is evident from following controlfile that i am using trim to discard any space then why it is giving an error.
LOAD DATA
TRUNCATE
INTO TABLE TABLE1
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
ID INTEGER EXTERNAL,
OPTION1 CHAR,
REF1 CHAR,
OTHER_REF CHAR,
TITLE "TRIM(:TITLE)",
FORENAME "TRIM(:FORENAME)",
SURNAME "TRIM(:SURNAME)",
JOINT_TITLE "TRIM(:JOINT_TITLE)",
JOINT_FORENAME "TRIM(:JOINT_FORENAME)",
JOINT_SURNAME "TRIM(:JOINT_SURNAME)",
I checked the bad file and count number of characters, they are 64 characters.
When i am inserting individual record from bad file by sql loader, it is loading

Probably your database character set is multi-byte. That is %UTF8 or AL16UTF16%
Post your NLS Database Parameters value
select * from nls_database_parameters;
In General varchar2(65) by default means 65 BYTES unless
you have changed your Defalut NLS_LENGTH_SEMANTICS parameter from BYTE to CHAR.

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"/>

SQL Plus in Oracle 10g XE -

How can i works in oracle 10g XE using the SQL Plus.
When I try to connect, show-me and error.

After installing XE poke a little in the file system directory where you installed.
In the bin directory youll find the sqlplus executable. In the network/admin directory youll find the tnsnames file with a service name by the name of XE configured.
So, as long as you hit that tnsnames file and connect with an unlocked user you should be OK.
sqlplus user/pass@XE
Potential problem you have some previous Oracle Client installation and you hit the tnsnames file from there you could add the XE configuration there too. Or use environment variables to switch over to the XE installation.
Try a tnsping XE and see what is says.

Migration from SQL 2000 to Oracle 10g

Hi every one,
This is the first i am posting to this forum.
I have a problem in migration of Sql Server database to Oracle 10g.
We use Microsoft Navision Axapta 3.0 SP4 as front end.
and Sql Server 2000.
All table and indexes are created in sql server by Navison only.
My Database size is 300 GB and now we face thousands of Problem with SQL server so we decided to make a intelligent move to oracle 10g.
As we have 1200+ users.
The problem i am facing when i tranfer all the table to my Oracle Database it gives a error out of buffer.
some time it gives me error about the index as few of our developer have create two indexex on one field.
So oracle identifies that there are two indexes on one field.
So pls help how can i solve this problem.
I have 1234 tables.
from
Mohd Sufian

Can you post the exact Oracle error you are getting? The ORA-xxxxx part is the most important for us to identify what particular problem(s) you're having.
Is your front-end certified to use an Oracle database? Particularly if the front end is creating database objects, it needs to know how to work with whatever database it is connecting to.

SQL 2005 to Oracle 10g migration

We are migrating from SQL 2005 on Windows to Oracle 10g on Linux. If any one has experience with this kind of migration please share the steps involved.
Also is it possible to migrate subset of data from SQL to Oracle or is migrating entire data/schema the only option?
Any help or direction in this is much appreciated.Thanks in advance

Hi spulyala,
There is no clear and simple way of doing this.
-The online data move migrates from one java connection/table to another java connection/table so you would need to have the source table already filtered.
-The offline data move dumps the information out of SQL Server one table at a time, a where clause may be able to be applied manually at this stage, and loads the data in using Oracle sqlldr.
Of course you can filter and manipulate the tables within SQLServer before migration, within Oracle after migration, and delete table representations from with the tool.

SQL performance slow -- oracle 10g to oracle 11g

Hi,
We are have two development server, here we can call server10 and server11.
Server’s having same hardware and OS, but different oracle version, server 10 and server 11 having oracle 10g and oracle 11g respectively.
Problem, when you run sql query in oracle 11g it’s very slow compare to oracle 10g server.
Here I have checked
1)     sga size – comparatively 11g size is big
2)     no full table scan
OS – SUN
DB: 11.1.0.7.0, 10.2.0.4.0

Please try to post the tkprof output of the trace of both. The reason for this that explain plan may lie to us about what has happened but trace would be the real picture only.

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.
