Help on Oracle Golden Gate [SQL Server to Oracle Database]

Hi,
I am planning to use Oracle Golden Gate to replicate data from SQl Server 2008 to Oracle database. I had below queries which I wanted to get clarity on before making a decision. It would be very helpful if anyone can clarify this
- Can I set-up OGG to synchronize only a subset of tables within a schema ? (for ex: 10 tables out of 50 tables in a schema)
- Once the synchronization is set-up after the Initial Load, can the synchronization be paused (for few days) and then resumed again seamlessly ?
Any help/input would be greatly appreciated.
Regards
Rajashekar

- Can I set-up OGG to synchronize only a subset of tables within a schema ? (for ex: 10 tables out of 50 tables in a schema)
Yes, the TABLE option in the extract needs to specify the table name (not a wildcard ( * )). The replecat needs to be done the same way.
Example:
--Extract--
TABLE <SCHEMA>.<TABLE_NAME>
--Replicat--
MAP <SCHEMA>.<TABLE_NAME>, TARGET <SCHEMA>.<TABLE_NAME>
- Once the synchronization is set-up after the Initial Load, can the synchronization be paused (for few days) and then resumed again seamlessly ?
Once the initial load is done, you can turn off the replicat for a few days. Only thing is that you need to make sure you have space for the trail files that will be generated and access to any backups/archive logs that you may need later.

Golden Gate SQL Server Replication

Hello Friends..
I need your help in getting some information about Golden Gate SQL Server replication. Could you guys please help me in finding an answers on how a highly transactional sql server does with clustering and replication ? How long does it take to get replica online to users ? Is there any good reading material about Golden gate sql replication? Please help

Documentation is always a nice place to start reading:
http://www.oracle.com/technetwork/middleware/goldengate/documentation/index.html
Regarding replication, please take into account that DDL replication is only supported between oracle databases.
As for your main question, it is all based on the configuration you use. If you have much going on on the source you might add replicats to process the workload in parallel

Need help in migrating data from SQL Server to Oracle

Hi,
I've created a database link in my Oracle Database 11g Express Edition connecting to our SQL Server 2005 Enterprise Database. Now, I'm having issues on migrating some fields. Mostly Text field in SQL Server to CLOB in Oracle. I've created a PL/SQL Procedure to do this but somehow these columns don't get all the value.
For example:
In my sql server, I have a table SQLTBL with a field REMARKS of TEXT data type. It has the following value.
This is line 1.
This is line 2.
This is line 3.
Now I created a table ORCLTBL in oracle with field REMARKS of CLOB data type.
In my procedure I do something like.
begin
for i in ( select "remarks" rem from "dbo"."sqltbl"@sqldb )
loop
insert into orcltbl ( remarks ) values (i.rem);
end loop;
commit;
end;
/When I select the data from oracle it will only show "This is line 1" and disregard the values after the new line character.
Is there a way to make this work?
Thanks,
Allen

Does the above mean, you have Three records or it is One record spanning in Three lines?
Now I created a table ORCLTBL in oracle with field REMARKS of CLOB data type.

for i in ( select "remarks" rem from "dbo"."sqltbl"@sqldb )

/When I select the data from oracle it will only show "This is line 1" and disregard the values after the new line character.
Probably, assuming that there is only One record, SQL server is sending the data as separate rows as opposed to a Single Row.
Can you provide the Output of below when executed from Oracle terminal? (I hope you understand the motive of query, and pardon my knowledge of SQL Server if the query below does not work :) )
select count("remarks"), "remarks" rem from "dbo"."sqltbl"@sqldb group by "remarks";

De registering the JMX agent from oracle golden gate monitor server.

Hi,
I configured a system to monitor the golden gate processes on the golden gate monitor server.
Now I don't want any more to monitor one of the server processes on the monitor server.
What is the procedure to deregister the jagent ? In my case the jagent is a embedded agent not a stand alone agent .
Thanks,

Oracle dblink to sql server, accessing multiple database on same sql server under one dblink

Hi, we have successfully managed to set up an Oracle dblink over to sql server and retrieve data.
The sql server user were using via the dblink has access to more than one database on the same sql server
But the question is how in oracle (if at all possible) do you prefix the sql statement to access this ?
Eg:
Sqlserver_prod has user sqlserver_user which appears to be set up as default database on sqlserver_db1
But we have select access to sqlserver_db2
all work fine as sqlserver_user
select * from table_fromdb1
select * from dbo.table_fromdb1
select * from sqlserver_db1.dbo.table_fromdb1
as does
select * from sqlserver_db2.dbo.table_fromdb2
over in Oracle
Oracle_db has dblink sqlserver_prod.world connecting as sqlserver_user
all working fine
select * from "table_fromdb1"@sqlserver_prod
select * from "dbo"."table_fromdb1"@sqlserver_prod
but how (if at all possible) do I access from oracle
sqlserver_db2.dbo.table_fromdb2
without having to create a new sqlserver_db2_user referenced in a new dblink
if oracle to oracle would be
select * from remote_oracle_schema.table@remote_oracle_db

Hi, ok cheers, I see, original gateway was connecting purely at host_name level
HS_FDS_CONNECT_INFO=sqlserver_host
Planning to amend this to be
HS_FDS_CONNECT_INFO=sqlserver_host//sqlserver_db1
With exisiting dblink
And to create new gateway
HS_FDS_CONNECT_INFO=sqlserver_host//sqlserver_db2
With new exisitng dblink,will see how we get on
Cheers again

Moving table from oracle 10g to sql server 2005 plz help!!!

Hi All,
I have a table in oracle that i have to move to sql server.
I have exported the table and the dmp file is around 150 MB.
I do not know how to import this file into sql server.
Can some one kindly update me as to which is the best way to do this,
i know the best people to answer this would be the sql server techs but just wanted to try my luck on OTN.
regards,

Hello,
you could use the Database Gateway for MS SQL Server, create a database link that uses the gateway, and then transfer the data from Oracle to SQL Server using in SQLPlus a command like the following:
copy from scott/tiger@ora102 -
insert TEST1@dg4msql -
using select * from test1@ora102 ;
Another solution is using a PL/SQL block, and how to do it is described in the following note in My Oracle Support:
"Insert Into Remote Table Select * From Local Table" Gives Error ORA-02025 Using DG4MSQL (Doc ID 790572.1)
I don't know whether it is the "best way to do it", but it is an alternative.
For inserting a flat file into SQL Server you really need to check with Microsoft. Or you can use 3rd party software: http://www.dbload.com/

Install oracle golden gate 11.1.1.0 for oracle9i on RedHat AS3 U6 issue

Hi expert,
I need install Oracle golden gate base on below combination:
GG version: 11.1.1.0 (x64)
OS version: Redhat AS3 UL6 (x64)
Oracle version: 9.2.0.8 (x64)
I set the .bash_profile for oracle as below:
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/9.2.0
export GGATE=/software/ogg
export PATH=$PATH:$ORACLE_HOME/bin:$GGATE
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$GGATE
However, after installation, when I run ggsci, it show below error message:
ggsci: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
I searched the libstdc++.so.6 in the server and found one in /lib64/ssa/libstdc++.so.6, I changed the LD_LIBRARY_PATH as:
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$GGATE:/lib64/ssa/
then this time it has below error:
ggsci: /lib64/ssa/libstdc++.so.6: version `GLIBCXX_3.4' not found (required by ggsci)
ggsci: /lib64/ssa/libstdc++.so.6: version `GLIBCXX_3.4' not found (required by /software/ogg/libxerces-c.so.28)
my question:
1. Is GG 11.1.1.0 supported on RHEL AS3 U6? From oracle official website, it seems only the EL 4 UL7+ or EL 5 UL3+ are supported.
2. If it's supported, how to resolve above error?
Many thanks for your help.

Hi,
I think GG version: 11.1.1.0 (x64) supports only oracle 10g and 11g databases.
Try GG version: 10.4.0.19 (x64) for oracle 9.2.0.8
Thanks.

Unable to configure Oracle Publisher in SQL SERVER 2008 R2

Hi, All,
I am trying to talk to my Oracle database from SQL server. I already had Oracle Client 11g installed in my SQL server.

1.Make certain that a current version of the oracle client code is installed at the distributor”, please install corresponding version of Oracle
Client tools on Distributor Box
2.Are you able to connect to your Oracle server from the Distributor Box?if so,Distributor
box needs to have Oracle client tools installed on it before you can setup replication , I hope you have installed the Oracle client tools on Distributor Box. If yes, check if using SQLPlus you can connect manually to Oracle server or not from your Distributor
Box.
Moreover,Please refer the below
Before attempting to configure the Oracle Publisher, SQL Server verifies that SQL*PLUS is accessible through the system path on the Distributor. If SQL*PLUS cannot be loaded, the following error message is shown:
"Unable to run SQL*PLUS. Make certain that a current version of the Oracle client code is installed at the distributor."
Try to locate SQL*PLUS on the Distributor. For an Oracle 10g client install, the name of this executable is sqlplus.exe. It is typically installed in %ORACLE_HOME%/bin. To verify that the path of SQL*PLUS appears in the system path, examine the value of the
system variable Path:
Right-click My Computer, and then click Properties.
Click the Advanced tab, and then click Environment variables.
In the Environment Variables dialog box, in the System variables list, select the Path variable,
and then click Edit.
In the Edit System Variable dialog box: if the path to the folder that contains sqlplus.exe is not present in the Variable
value text box, edit the string to include it.
Click OK on each open dialog box to exit and save changes.

Related to migration of db from sql server to oracle 11 g

We're trying to migrate a Sql server managment studio database to Oracle 11g using SQL Developer 4.0. We can successfully connect to both Sql server managment studion 8.0 and Oracle 11g using the tool, as well as click through the Migration Wizard and start the migration.
This opens the Database Migration dialog box, which indicates the capture process starts normally. we get the following error:
ora :01440 : can not insert null into migrlog (id column) ,
\and then after some time , i get an error that migration failed
i am not getting the reason,I thing it may be due to reason that , I have table's column in my source db with more than 30 character.
If i am migrating one by one table . then it is not giving any error, and identifier name is getting shrink in 30 character. but i am not getting the view , stored procedure , indexes , and others
then what is the solution for that, somebody pls suggest any help?????????????

Pl do not post duplicates - related to migration of db from sql server to oracle 11 g
Continue the discussion in your original thread
The error message is explicitly clear
ora :01440 : can not insert null into migrlog (id column)
Your process is trying to insert a NULL value into the ID column, which presumably cannot be NULL

CONVERT function in SQL Server to oracle

All,
How to convert CONVERT function in SQL Server to oracle, below mentioned format is in SQL Server:
variable1 = convert(numeric(20), SUBSTRING( parameter1,parameter2,parameter3)
parameter1 datatype nvarchar2(100)
parameter2 datatype bigint
parameter3 datatype bigint
I did bit R&D, but was not successful..but still getting on..
If any help that would be great...
Regards,
~ORA

You cannot specify the precision/scale or length of input paramters to a stored procedure in Oracle, or at least the pl/sql engine does not respect the sizing. Assuming that you want to do something with variable1 in the procedure, and not just return it, the Oracle equivalent would be something along the lines of:
SQL> CREATE FUNCTION f (p_param1 IN VARCHAR2,
2                     p_param2 IN NUMBER,
3                     p_param3 IN NUMBER) RETURN NUMBER IS
4     l_var1 NUMBER(20) := SUBSTR(p_param1, p_param2, p_param3);
5 BEGIN
6     RETURN l_var1 * 10;
7 END;
8 /
Function created.
SQL> SELECT f('ABC10DEF', 4, 2) FROM dual;
F('ABC10DEF',4,2)
              100You may need to adjust the return type to match what you are actually returning.
You can also use this iin a direct assignment in pl/sql without doig a select, something like:
SQL> DECLARE
2     l_num NUMBER(20);
3 BEGIN
4     l_num := f('ABC10DEF', 4, 2);
5     DBMS_OUTPUT.Put_Line('The number is: '||l_num);
6 END;
7 /
The number is: 100John

Insert data into oracle based on sql server data(here sql server acting as source to oracle and destination to oracle)

Source is Oralce. Destination is SQL Server.
Requirement - I have to fetch sql server server data (empid's) based emp table and send this as input data to oracle to fetch and empid's are common.
I cannot use merge or loopkup or for each as oracle have too many records.
For example - In MS SQL - i have empid=1,2..Only these records, I have to fetch from oracle source into sql server destination. For this, I have adopted the below approaches...The major problem I face, when i build a empid's as a string, it is taking only
4000 chars. My string lenght is 10000. How do I breakup this string lengh and send to data flow task till all broken strings length passed to DFT.
Approach-1
created two variables - oraquery string, empid string
step1 - ms sql database - created sql task - declare @empid varchar(max)
SELECT @empid=
Stuff((SELECT ',' + empid
        FROM
        (SELECT DISTINCT convert(varchar(10),empid ) empid FROM emp
         ) x
        For XML PATH ('')),1,1,'')
select @empid =    '(' + @empid + ')'
select @empid
resultset=singlerow
resultset=resultname=0; variablename=User::empid (empid is declared as string)
step2 - oracle database - created data flow task
created oledb source
I put this statemnt in oraquery expression - "select * from dept where dept in "
+ @[User::empid] + "
expression=true
[OLE DB Source [1]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E14.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80040E14 Description: "ORA-00936: missing expression".
Approach-2
created three variables - oraquery string, empid int, loop object--when I put int then it is automatically setting to 0
step1 - ms sql database - created sql task - SELECT DISTINCT convert(varchar(10),empid ) empid FROM emp
resultset=fullresult
resultset=resultname=0; variablename=User::loop
step2 - created a for each loop container
for loop editor - for each ado ennumerator
enumerator configuration - loop
variablemapping - variable=empid;index=0
step3 - oracle database - created data flow task (outside for each loop. If I put inside it is taking long time)
created oledb source
I put this statemnt in oraquery expression - "select * from dept where dept in "
+ @[User::empid] + "
expression=true
Data inserting in a destination table but empid=0.

Sorry didnt understand if your step3 is outside loop how
@[User::empid] will get values for the empids from User::loop. The iteration happens inside loop so you
need to have a logic to form the delimited list inside using a script task or something and concatenating everything and storing to variable @[User::empid]
. Then only it will have full value used to be used in step3 query

Taking snapshot of oracle tables to sql server using transactional replication is taking a long time

Hi All,
I am trying to replicate around 200 oracle tables onto sql server using transaction replication and it taking a long time i.e the initial snapshot is taking more than 24 hrs and it still going on.
Is there any way to replicate those these tables faster?
Kindly help me out..
Thanks

Hi,
According to the description, I know the replication is working fine. But it is very slow.
1. Check the CPU usage on Oracle publisher and SQL Server. This issue may due to slow client processing (Oracle performance) or Network performance issues.
2. Based on SQL Server 2008 Books Online ‘Performance Tuning for Oracle Publishers’ (http://msdn.microsoft.com/en-us/library/ms151179(SQL.100).aspx). You can enable the transaction
job set and follow the instructions based on
http://msdn.microsoft.com/en-us/library/ms147884(v=sql.100).aspx.
2. You can enable replication agent logging to check the replication behavior. You may follow these steps to collect them:
To enable Distribution Agent verbose logging. Please follow these steps:
a. Open SQL Server Agent on the distribution server.
b. Under Jobs folder, find out the Distribution Agent.
c. Right click the job and choose Properties.
d. Select Steps tap, it should be like this:
e. Click Run agent and click Edit button, add following scripts by the end of scripts in the command box:
-Output C:\Temp\OUTPUTFILE.txt -Outputverboselevel 2
f. Exit the dialogs
