Making Application Database (SyBase, Oracle, MySql) Independent

Hello Experts ,
I am having an application running on SyBase DB and frontend is VB.NET. I would like to make it somehow databaseindependent. Means, I want somthing like on installation time if I specify Oracle then Oracle db to used else Mysql or else SyBase.
Also, is there any solution for the coding too ? means, in case of ORACLE databse the relevent code to be installed on machine, in case of sybase only relevent code to be installed.
I dont want all 3 codes to be installed on machine as it will lead to space problems.
Please send me links , docs at [email protected]
Warm Greeting to all of you.

There are a couple of question here,
Does the application is installed on the same system of database?
If yes, Does the Oracle and Sybase have been installed
while Application is installing?
   If yes, then you can try to detect such database
installation (different databases on different OS have
different ways to find out DB installation)
   If no, there's no way your installation program can
predict the DB of choice, user who perform installation must provide.
If no, Does the server have DB specific client installed
while Application is installing?
   If yes, then you can try to detect such database
client installation (different databases on different OS
have different ways to find out client installation)
   If no, there's no way your installation program can
predict the DB of choice, user who perform installation must provide.

You're free to come to that conclusion, but you would be
totally wrong.

Migrate peoplesoft sybase HR database to oracle 11g

Hi All,
We am looking to migrate from sybase 12 to Oracle 11g. We are not sure on which path to choose for this migration to be done. Ths sybase Database is around 55 GB. Below are few questions. Please let me know. The down time on this database can not be more than 2 days at the max.
1. What is the best and fastest way to do this, if there is one?
2. Any Documentation on steps involved in migration?
3. Do we have to use any 3rd party tools for this?
4. Can we achieve the data migration with sql loader, if yes is it the suggested way to do this and is there any documentation on this?
I tried sql developer to do the migration but it did not go well and finally found that it is not the way to migrate a Database with peoplesoft environment, below is the link to explain more about what I have done with sql developer.
If there is any other information required, below link has almost all the information.

1)     Build an Oracle Demo system patched to the same release level as the current production system.
2)     Launch Application Designer and compare the production system to the demo system so you may capture the modifications.
3)     Load a custom table with the tables listed in the MVPRDEXP.EXP in the production system. Run a script to create an export script for all PSRECDEFN where the RECTYPE is 0. This identifies all application data tables. You may want to dms export large tables in parallel.
4)     DMS Import the exported data into the Oracle instance.
5)     Reapply the modifications.

Accessing mysql database from oracle using dg4odbc

I've been trying to create a database link from a MySQL database to Oracle using the Oracle dg4odbc gateway. I downloaded and installed DataDirect's ODBC package which includes mysql ODBC library (ddmysql24.so) and a generic ODBC libary (libodbc.so). After creating the DSN in odbc.ini, I tested it and it can connect to the mysql database. Then I created the init{SID}.ora file in hs/admin directory, added dg4odbc lines in the listener.ora, and added lines in tnsnames.ora. Then I tnspinged the new SID with success. Finally, I created the database link. However, when I tried to access the database link using the commands "select * from mdl_user@moodle;", I got the ORA-28500 error like the following:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[DataDirect][ODBC 20101 driver][20101]You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right
syntax to use near '"mdl_user"' at line 1
ORA-02063: preceding 2 lines from MOODLE
My mysql database is utf8 by default. Do I have to use latin1?
It seems to me that the dg4odbc translates the sql commands incorrectly (having double quotes around the selected table).
Any help is greatly appreciated.
Jeffrey

The syntax error occures for example when MySQL isn't running in ANSI mode and thus does not allow double quotes around the objects. DG4ODBC 11.1.0.6 by default always adds double quotes to table/column/view names.
A quick test to check if you hit the double quote issue would be to set the MySQL DB into ANSI mode:
- Open SQL*Plus
- execute:
DECLARE
ret integer;
c integer;
BEGIN
c := DBMS_HS_PASSTHROUGH.OPEN_CURSOR@moodle;
DBMS_HS_PASSTHROUGH.PARSE@moodle(c, 'SET SESSION SQL_MODE=''ANSI_QUOTES'';');
ret := DBMS_HS_PASSTHROUGH.EXECUTE_NON_QUERY@moodle(c);
dbms_output.put_line(ret ||' passthrough output');
DBMS_HS_PASSTHROUGH.CLOSE_CURSOR@moodle(c);
END;
- Now run your select statement
=> if it now works, you can permanently change the MySQL config to be ANSI compliant or you can apply the 11.1.0.7 patchset to DG4ODBC.

thanks & regards.

The error message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified {IM002}" is self explainind - DG4ODBC is not able to find the ODBC DSN you created.
In your gateway init file you configured the DSN: HS_FDS_CONNECT_INFO = testmysql
And according to the Windows ODBC Admin screenshot you created a DSN called testmysql - unfortunately you created it as a USER DSN. But DG4ODBC needs a SYSTEM DSN. The reasin why it needs a system DSN is that by default the Oracle listener is running in the local system account. So when you create an ODBC USER DSN it can be access by the user who created it, but nobody else can use it - also not the local system account which is serving the Oracle listener. So you need to create a system DSN that every user on this machine can use the DSN (including the local system account) .

Export - Import in Oracle Application Database

The export in Oracle Applications Database works fine.
But the import always show some issue and sometimes never completes.
Even if it completes it complete with error , how to ensure an error free export/import ?
How to handle a table movement if the table consists of a LONG column ?

The errors are cannot import this tables..
Also mostly are of Long tables..Any IMP-XXXXX or ORA-XXXXX messages?
Can you explain how long objects are exported and imported ?What type of objects?
What is the database version?
Are you doing a full database import?
Also sometimes import hangs for 2/3 days?Does it hang when importing a specific object?
Did you follow the steps outlined in the following notes when you did the Export/Import?

Auditing in oracle 10g database and oracle 10g application server

Dear friends,
We have oracle 10g application server and oracle 10g database server in place.My criteria is to audit users connected using oracle application user credentials to the database.
Can you please tell me how can i do it.
Thanks & regards,

Its the database connection you want to track. The session audit will show where it came from.
Auditing is turned using this command:
alter system set audit_trail = DB scope=spfile;
Note: The use of spfile will require a DB bounce before audit starts
To audit Sessions:
audit create session;
Query by Audit Type:
SELECT A.USERNAME,
OS_USERNAME,
A.TIMESTAMP,
A.RETURNCODE,
TERMINAL,
USERHOST
FROM DBA_AUDIT_SESSION A
WHERE USERHOST = <replace with iAS servername> ;
By User
SELECT USERNAME,OBJ_NAME,ACTION_NAME , TIMESTAMP
FROM DBA_AUDIT_TRAIL WHERE USERNAME = 'SCOTT';
Check for users sharing database accounts
select count(distinct(terminal)),username
from dba_audit_session
having count(distinct(terminal))>1
group by username;
Attempts to access the database at unusual hours
SELECT username, terminal, action_name, returncode,
TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS'),
TO_CHAR (logoff_time, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') <
TO_DATE ('08:00:00', 'HH24:MI:SS')
OR TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') >
TO_DATE ('19:30:00', 'HH24:MI:SS');
Attempts to access the database with non-existent users
SELECT username, terminal, TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE returncode <> 0
AND NOT EXISTS (SELECT 'x'
FROM dba_users
WHERE dba_users.username = dba_audit_session.username);
Other audits you might consider:
audit grant any object privilege;
audit alter user;
audit create user;
audit drop user;
audit drop tablespace;
audit grant any role;
audit grant any privilege;
audit alter system;
audit alter session;
audit delete on AUD$ by access;
audit insert on AUD$ by access;
audit update on AUD$ by access;
audit delete table;
audit create tablespace;
audit alter database;
audit create role;
audit create table;
audit alter any procedure;
audit create view;
audit drop any procedure;
audit drop profile;
audit alter profile;
audit alter any table;
audit create public database link;

Connect to a mysql database with Oracle 9i

Hello,
how can I connect to a non_oracle-database in "Oracle 9i".
I created a ODBC data source. In Oracle8 I needed OCA. But in 9i I believe the OCA is replaced by another thing.
I wanted to connect in SQL*PLUS with:
username/password@odbc:mysql
But I get the error: ora-03121 "no interface driver connected - function not performed".
How can I connect to another database?

I've solved the DW problem by changing the site folders from
'db' to 'wwwroot' e.g. 'C:\CFusionMX\db\' is now
'C:\CFusionMX\wwwroot\
However I'm now back to my original problem. I've lost my
mqysql connection in CF Adminstrator. Before I made these changes I
could connect to my mysql databases using the following settings:
JDBC URL: jdbc:mysql://localhost:3306/test
Driver Name: MySQL Connector J
using the following Java path and file:
C:\CFusionMX\wwwroot\WEB-INF\lib\mysql-connector-java-3.0.17-ga-bin.jar
Now these settings give me the following error:
"Connection verification failed for data source: javaserver
[]java.sql.SQLException: SQLException occurred in JDBCPool
while attempting to connect, please check your username, password,
URL, and other connectivity info.
The root cause was that: java.sql.SQLException: SQLException
occurred in JDBCPool while attempting to connect, please check your
username, password, URL, and other connectivity info"
Any suggestions on this would also be welcome.
Thanks again to everyone for their help.
Sincerely,
Graham A. Kerby

Migrate peoplesoft sybase HRMS database to oracle 11g

Hi All,
I want to know if I can migrate a sybase peoplesoft HRMS database to oracle 11g using sql developer 3.0. I am trying to do this following the steps given in the link below but it is taking for ever for the convert step, I could see the messae saying building converted model.
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/sqldev/r30/SybaseMigration/SybaseMigration.htm
The sybase database is 55GB and the version is 12. There are around 20,000 tables in Sybase Database.
Please advise, if this is possible with SQL Developer??
If yes, how long this process might take(for each step in the above link), based on any past convertions of the same size database??
If this is not feasable with SQL Developer because of the complexity of the database, are there any other tools we can look into which might be faster/better than SQL Developer.
Please advise.
Thanks..

Hi Dermot, Tanks for the reply.
"Do you know the number of views and procedures captured". Below is the ouput from some of the tables in migration repositary.
count from md_derivatives table, grouped by derived_type.

Count from md_views table 34316
Count from md_additional_properties table 110322
"Is there a chance the convert phase has hung, or does it refresh ever so ofter with details of another object being "migrated"?"
It is not hung. I can see the message 'Translating views' right now, and the View names change often but not fast roughly every minute. When I checked for what the session is doing, I could see the below two sql statements.
SELECT PROP_KEY, VALUE, PROPERTY_ORDER, CONNECTION_ID_FK
FROM MD_ADDITIONAL_PROPERTIES
WHERE REF_ID_FK = :1
ORDER BY PROPERTY_ORDER;
SELECT ID
FROM MD_TABLES -- Some times this is MD_VIEWS
WHERE SCHEMA_ID_FK = :1 AND UPPER (TABLE_NAME) = UPPER (:2)
"What is the current "Being migrated" information?"
Translating View xxx.
"Does the tablespaces your migration repository schema is based on have sufficient space?"
Yes, Since there is no data at this point, it is all done in one table space which is set to grow UNLIMITED. At this point the size of the table space is a little over 500M.
"Is SQL Developer being run on the same machine as the Oracle database containing the migration repository? (conversion can be alot quicker for procedure,view,trigger conversion if SQL Developer is on the same machine as the repository)"
NO. SQL developer is running on my machine but the migration repositary is in the database which is on HP-UX box. Below are some of the details of the server. Also, since the database in on HP-UX, I couldn't find SQL developer for UNIX. I also read in the release note of 3.0 that it is not supported with UNIX, Is that right? else is there a way I can install SQL developer on the Unix server and that might improve the performance!, if yes, please guide me with the steps to do this installation.

Oracle E-Business Suite 11.5.9 Application & Database

Hello Folks,
Happy New Year.
Need quick document in meta-link or blog which will help me connect the database on other server to the Oracle E-business Suite EBS application
The scenario:
Application and Database are on the server_A (hostname ServerA)
I have made a cold backup of the database and restored it on Server_B ( hostname ServerB) { let us say I migrated / moved the database to another machine }
Database starts and listener starts fine on ServerB
Now, the question is: How can I connect or point the Oracle EBS 11.5.x application to the Database on ServerB ?

Thanks Hussein,
SQL> select owner, object_type from dba_objects where object_name = 'FND_NODES';
OWNER OBJECT_TYPE
APPLSYS TABLE
APPS SYNONYM
SQL> SELECT trigger_name , status FROM user_triggers WHERE table_name = 'FND_NODES' ;
TRIGGER_NAME STATUS
FNDSM ENABLED
UPNAME ENABLED
Hussein, the specific question is as such.. I don't know if this is possible or not.
Can you have two databases connected to the same application.
Scenario:
SERVER_A = has both the application and database
using DBVISIT software / which is an alternative to DataGuard ... which transfers the archive log files to the other server, I have moved or made the standby server as my primary database . see here for details http://blog.dbvisit.com/the-power-of-oracle-services-with-standby-databases/
Two Questions:
1) How to re-configure my Application ( Oracle EBS ) to point to the same Database but on a different hostname/server/ip address which you have answered and referred to the MetaLink documents ( thank you for that )
2) Can I have two pointers to the database in the Application, to the existing one and to the one on standby server ?
a) is this possible ?
Also,
now regarding changing the hostname for the database in Oracle EBS apps you have recommended
Rapid Clone Documentation Resources For Release 11i and 12 [ID 799735.1] -- Rapid Clone of E-Business Suite Release 11i
How to change the hostname and/or port of the Database Tier using AutoConfig [ID 338003.1]
How to get a clean Autoconfig Environment ? [ID 391406.1]
Using AutoConfig to Manage System Configurations with Oracle Applications 11i [ID 165195.1]
Now, I have read those documents which is kind of summarized here:
http://oracleappsdba1.blogspot.com/2009_07_01_archive.html
I hope my question is clear.
I have already moved the database to another Machine ( different hostname + different IP ) and the application is on the previous machine
So, to connect the Application on SERVER_A to the same database but on a different machine SERVER_B I will have to only follow the instructions mentioned in Metalink 338003.1 or do I need more steps ?

How to conncet mysql database and oracle database 11g2 on linux 5.4

How Migrate MySql Database to Oracle

Hi...
I like Migrate MySql Database to Oracle, can help me?
Alexandre

I am trying to migrate a MySql to an Oracle database. I have not had any problem setting up the migration workbench.
What I am having a problem with is copying the source database to the Oracle DB - I have verified that the host name is correct - and the MySql is at the default 3306 port number.
What my problem is that the root user on the Linux server is not the user with DBA priviliges - instead a user called admin is the user on the linux box that has DBA priviliges.
Is my only way around trying to get the root user assigned DBA priviliges in order for this extract to succesfully happen - and if so, how do I go about assigining DBA priviliges on the MySql database to the root user?
Any help will be appreciated.
Thanks

Unable to connect to Oracle Applications database (afscpgcs) after clone

Hi,
I have just moved (clone using rapidclone) two of our 11.5.10.2 install from a solaris SPARC 8 to 10 . After the clone, while discoverer 10g works perfectly well in one environment, it is giving the error below in the another environment.
- Failed to connect to database - Unable to connect to Oracle Applications database (afscpgcs)
Notes:
1. For the 2 environments, nothing as changed apart from the hostnames.
2. The password has not changed on both - from source to targets.
3. This happens when launching discoverer 10g from Apps.... discoverer works well on it own if not launched from apps.
I raised a SR with oracle and the 2 things they said have not worked. they said
1. change signon password case parameter - but I cannot find that in the list of system parameters on our system.
2. The other note says apply patch 6430269 and I can confirm this patch has been on the system for sometime.
Please advise on this if you have come accross this before and you can help here.
Thanks

Thanks for your concern. I have used the notes you listed but no luck. One thing I have to point out here is that I have always cloned from solaris 8 to 8 for years without this problem. Now I am cloning from solaris 8 to 10 and the problems is on just one environment. The other is working well. The problem seems to be related to the apps password but the password has not changed at all. Also, I have tried to change the password to something else and ran autoconfig but no luck. Please help
