Whether using Oracle after migrating from MySQL be easy or not?

Though oracle is tough secured one, I don't know exactly the complexity of using Oracle database. Using MySQL 4.1.22 in my website https://www.puntercalls.com/ . Though the site is based on providing share market tips, it deals with a huge amount of stock market data and in much more real time basis hand-to-hand with NSE and BSE info which means a tough security is the utmost demand of the time.
My question is whether using Oracle after migrating from MySQL be easy or not. You can check my site at https://www.puntercalls.com/ for different real time data updation parts.
Kind suggestions are greatly appreciated in advance!

Hi,
As you are really asking about how to setup and use securioty features in an Oracle database it woul db ebetter to raise the question in this forum -
Forum: Database Security - General
Database Security - General
They will have more knowledge about Oracle security features and which it would be best for you to use.

Implementing "Temporary Tables" in Oracle after migrating from SQL Server

Hello,
Some stored procedures referencing temporary tables in SQL Server were migrated to Oracle. In the Oracle DB, these stored procedures are invalid. In a bid to make them valid, I created the referenced temporary tables in my Oracle DB, via SQL*PLUS having logged into the database as the appropriate user. And when I query the user_tables view, I see the temporary tables that I created. Thereafter, when I compile the stored procedures, I still get the message: PL/SQL: ORA-00942: table or view does not exist. And the stored procedures remain invalid. Pls,what do I do ?
Thanks for your cooperation

Chux,
The Migration Workbench should have created all the necessary temporary tables as part of the process to convert the stored procedures. Can you post the example part of the T/SQL stored procedure and what we converted it to?
Our support for Temporary Tables is discussed in our reference guide.

Can only access emails through OWA after migration from exchange 2007 to 2013

can only access emails through OWA after migration from exchange 2007 to 2013, in other words unable to access mails through outlook or from other Applications services.
needed RCA ... plz help..

Hi,
From your description, you can send and receive messages only when you use OWA after migration from Exchange 2007 to Exchange 2013. If I have misunderstood your concern, please let me know.
In your case, I recommend you create a new test mailbox in your Exchange 2013 and check if you can send and receive messages on Outlook. If yes, it is recommended to create a new profile to solve this issue.
Hope this can be helpful to you.

DB Migration from MYSQL to ORACLE Using Offline Capture

Hi
Am doing a database migration from MySQL to Oracle using SQL Developer (version 2.1.1.64). So far, I've successfully captured the MySQL database and converted it to the Oracle Model. However, when generating offline scripts to create the converted model schema into Oracle DDL scripts it managed to generate SQL to create: 1) User 2) Sequences 3) Tables 4) Triggers and 5) constraints.
It has created the SQL to add the primary key constraints and index constraints. Although it did the foreign key constraints in the SQL, the foreign key constraints seems to have missed the cascading options for the foreign key constraint. I.e. theres no reference of whether the foreign key constraint will restrict on delete or cascade etc.
We have a foreign keys in the MySql database that have different cascading options and these have not being ported over into the migration SQL. Therefore, all the foreign keys generated in the SQL by default are cascade to restrict on delete.
Does 'Generate Oracle DDL' not take into account a foreign key's on delete cascading option?
Any help or information would be greatly appreciated.
Thanks

Hello,
that reminded me for the following thread:
Migration Microsoft SQL Sever 2005 to Oracle 11g cascade on delete problem
That is a similar issue, isn't it?
I opened a bug for that, and it will be fixed in SQL Developer 3.1 (not in any 3.0 Early Adopter version). If you hit the same issue, there is no other way then using the workaround as used in the mentioned thread.

Problems while migrating from mySql DB to oracle DB

Hi All,
I'm using sql developer tool to migrate from MySql DB to oracle DB. I followed the below steps.
1) I've created oracle and mysql connections successfully.
2) I've captured Mysql data and I'm able to see the captured model in ' Captured Models ' window. After that right clicked on the captured model and selected ' Set Data Mapping'. Selected ' apply ' button without changing anything. After that I've right clicked on the captured model and selected ' Convert to Oracle Model ' . It has shown the converting process. After some time it has shown conversion completed successfully.
But converted model is not visible in ' Converted Models ' window.
Can anyone kindly assist on how to migrate from MySql Db to Oracle DB?
Thanks,
Saty.

Hi,
We did mysql to oracle migration some time back and played with workbench tool and many other softwares available.
However our experience was not so good with these tools, each tool had its own limitation and was not able to migrate 100% data. Even the speed of migration was too slow which would have violated our production SLAs.
So after spending a month with these tools we finally decided to create our own scripts for data migration. We used tools like TOAD and SQL Yok to create the DDL for the tables and other DB objects.
For the data migration we downloaded the mysql data in flat files and used sql loader to upload the same data in oracle. Even if this was a time consuming activity but this resulted in 100% data migration with no record getting failed and the time taken for this activity was around 6 Hrs in comparison to time of 24-28 Hrs that the workbench tool took.

Out of memory error in migrating from mysql to oracle

Hi,
I'm trying migrate from mysql to oracle9i. The hardware and software requirements are matching or even much higher than mentioned in the documentation. I have installed OMWB is properly(hope so). When I try to migrate the desired database from mysql to oracle, the repository, the Oracle model are created successfully. But while migrating data, say for around 35000 rows insertion everything works pretty fine. But after sometime, the migration stops and no error or anything appears in the screen.And in the Errorlog I get "OutOfMemoryError".
I tried to migrate single table also. But I still get this problem after sometime. The tables may contain from 10 - 130000 rows...
I even tried to change the %JRE..% memory value to 64M or 128M in the omwb.bat file and the O/s is Microsoft Windows XP, RAM 256MB.
Any help is much appreciated.
Thanks in advance.

Hi Viji,
did the message in the error.log provide any extra information? For example, was the OutOfMemory error prefixed with a string
like "cannot create new native thread" ? My suggestion to workaround the problem would have been to increase the JVM heap size to 128
but this appears to have been unsuccessful for you. Can you send a mail to the Migration Workbench support services
([email protected]) explaining the problem, and attach the full error.log file please ? (please also copy me on the mail).
In the meantime, you can workaround this by migrating the schema only (there is a switch on step 3 of the migration wizard asking:
"Do you want to migrate the table data to Oracle?" - just select the "No" option). When the schema has migrated, you can then use the
offline data loading facility to migrate the data. This uses data extraction scripts and SDQL*Loader to migrate the data to the target
Oracle database.You can learn more about the offline data loading facility from the plugins referenceguide (from the Help menu in
the Migration Workbench).
I hope this helps,
Tom.

Hotkey (Ctrl+B) is not working after migration from Forms 6i to 10g

Dear Gurus,
Need your help regarding the following problem:
After migrating from Forms 6i to 10g (Rel 2), Ctrl+B (used to list the blocks in a form) hotkey is not working anymore (all other hotkeys are working fine). I've checked my FMRWEB.RES and it contains an entry for Ctrl+B:
66 : 2 : "Ctrl+B" : 70 : "Block Menu"
Additional Information:
OS: AIX
NLS_LANG = UTF8
fmrweb_utf8.res also contains the same text for Ctrl+B as above.
I tried to reproduce it on my Windows Machine (with NLS_LANG set to AMERICAN_AMERICA.WE8ISO8859P1) and its not working as well. I don't have right to put move files on AIX server but i can try anything (on my local system) suggested by the Oracle gurus.
Best Regards,

Dear Gerd,
"are you sure, that it is the hotkey"
Yes, i am dead sure. Since:
(1) It was working fine in forms 6i
(2) If you run a form and select Help => Keys, you will see Ctrl+B on the top of list
The problem is its not taking into account the keys which i am defining in the file (although i am following the same procedure detailed on metalink.oracle.com).

Migration from MySQL - connection problem

I've just installed OMWB 1.3.1 for WINDOWS and created repository in ORACLE 8.0.5 DB.
When I enter Source Database Details in Capture Wizard and push Next button nothing is happened. In OMWB log-file I've found the following message among many others:

Hi Vladimir,
I send you a message from the Migration Workbench team that solved my problem. I hope this will resolve yours too.
Bye,
Pierfrancesco
Hi Pierfrancesco
MySQL 3.22, 3.23 Requirements
In order to migrate from MySQL to Oracle, you must install the MM MySQL JDBC
driver release 1.2a on the same system as the Migration Workbench. You can
obtain this by downloading the MM MySQL JDBC driver from the WorldServer Web
site at:
http://www.worldserver.com/mm.mysql
Copy and unzip the mm.mysql.jdbc-1.2a.zip file to your
%ORACLE_HOME%\Omwb\drivers directory. This automatically creates a new
directory called
mm.mysql.jdbc-1.2a within the drivers directory.
Can you please verify that you have this driver extracted to the above
specified directory. Another check you can do is see whether all the files in
the zip
have extracted.
Please refer to the Release notes which you have access to by selection the Help
drop down menu in the Workbench.
I hope this helps
Best regards

After Migrating from 10g to 11g Geeting problems with Guided navigations.

After Migrating from 10g to 11g Geeting problems with Guided navigations and section navigations not working.
And we are getting the following error <<odbc driver returned an error (SQLExecDirectW)>> where we have used navigations.
In 10G we have Guided navigation Reports to display the Reports links and intermediate reports for conditionally displaying the Dashboard section(Reports) but after migrating to 11g Guided navigation reports and conditional reports are not working..
We know that in 11g section navigation replaced with conditions and Guided navigation replaced with action link.. but
do we need to recreate those reports in actions and condition or is there any work around avoid reworking.

Hi Both,
Thanks for the reply ...
For Guided navigation we are getting like below error:
Odbc driver returned an error (SQLExecDirectW).
For Conditional dashboard section we are getting like below error:
"saw.aViewsToRefresh = [];saw.aViewsToRefresh['d:dashboard~p:1egt6il5utl0uu8n~s:3jsmgfs3c1r4tn7c~n:condition'] = true;saw.aViewsToRefresh['d:dashboard~p:1egt6il5utl0uu8n~s:nos5q43jvjmi643b~n:condition'] = true;"

Migration from MySql to Derby

I am currently migrating from MySql to Derby.
I have been developing a MRPII package for a while now and whilst my classes worked with MySql I am finding difficulty with implementing them using Derby.
I have developed a GUI interface for MRPII functions and use a Database Interface class to connect to the database.
The Database Interface class gives me the capability of reading and writing from a database.
I extend this capability to sub classes ie part, customers, suppliers, work orders.
The problem I have is with the ' "+standardCost+" ' type statements. In MySql, the database engine recognises that the standard cost variable is a double though using Derby I get the following Errors.
SQL Exception: Columns of type 'DOUBLE' cannot hold values of type 'CHAR'. In Save Data error code30000
SQL Exception: Columns of type 'DOUBLE' cannot hold values of type 'CHAR'. In Save Data error code30000
Executed statement INSERT INTO stock VALUES('BUDGET500','A1', '100.0','50.0','1.0','100.0')
Executed statement INSERT INTO part VALUES('BUDGET500', 'PENTIUM','76.0', '86.0','EACH','MP','7','33')
The only solution I see is giving each subclass of Database Interface the individual capability within that class to connect to the database and use prepared statements.
Does anyone know if Derby has the capability of processing the updates using a similar format as shown in my code.

I am currently migrating from MySql to Derby. Dear God, why?I am using the embedded functionality.
>
I have been developing a MRPII package for a whilenow
MRP as in "manufacturing resource planning"?Yes

and whilst my classes worked with MySql I am
finding difficulty with implementing them using
Derby.That suggests that your Java code relies too heavily
on MySQL features. You didn't make your code
portable enough.

be true for all databases. MySQL appears to be doing
an implicit conversion from string to double. Bad
idea.

dates for you? If not, you're in for a bumpy ride.
The only solution I see is giving each subclass of
Database Interface the individual capabilitywithin
that class to connect to the database and use
prepared statements.I would not have a single database interface. Each
class has its own requirements. How can a single
class know about all of them? Better to break your
persistence layer into several interaces, one per
persistent class.That is what I thought

You don't use prepared statements, which would help
with your portability issues.
You have SQL embedded in the objects. I'd move it
out into a separate persistence layer.
You might want to read about Hibernate, an
object/relational mapping layer. You've got objects
and tables. Hibernate tools or Middlegen can
generate the XML mapping files for you. Once you
have those, you'll find that Hibernate will make
porting to another database a lot easier. It can be
as easy as changing configuration files.
I'd also look into Spring. It has some great
plumbing to help you deal with databases and lots of
other stuff.

Increase in CPU Utilization after migration from APEX 3.1.2 to APEX 3.2

Has any noticed any increase in CPU Utilization after migrating from APEX 3.1.2 to APEX 3.2?
Thanks,
Mark

Hi Mark,
Take a look at some of the usage reports within APEX (sessions, page views etc) to get an overall feel for where the time is being consumed.
You'll also find it useful if you can run a statspack report (or AWR, ASH etc) during a busy period to be able to drill down into where that CPU is being spent.
There's no magic answers here unfortunately, you need to track it down to where the time is being spent before working back up to find out where best to tune it.

But I cannot add SSL because it complains about "unable to obtain a valid certificate for SSL communication information. Please verify that the adress and port are correct and that the LDAP directory has been configured with a valid certificate.
So I cannot understand why users cannot authenticate with zenagent.
There's a TID about zcc login failures after 11.3 upgrade.

We ran into the above.

Just got a new imac and my iwork software wont work. I have the serial numbers but after migrating from my old mac running OSX tiger it won't even give me that opportunity. I do not have any discs as this was downloaded. Help

Hi, hopefully you guys can help me out, I just
purchased a G5 iMac to replace my aging dell desktop,
and now i'm more or less completely os x dependant
(I've had an ibook for a few months now). Anyway, I
have a few questions:
1. Does anyone know of a (free) mail notifier tool,
that will alert me when I recieve new pop3 mail? I
used to use AIM for this in windows
The built in email program does sound an alert for new messages.
2. Anyone know of a good (free, again) IRC client?
iChat works well.
3. I noticed earlier that my screen was flickering,
it seems to have subsided for now, but is that normal
to encounter in a new display? It wasn't really bad
flicker, but I could see it.
No idea.
4. I leave my desktops on 24/7x365, will that be a
problem with this iMac? Display shuts off of course
after 30 mins
You could set the iMac to go to sleep after non use. My Macs are
always sleeping when not in use, waking them up takes seconds.
Unlike windoze, never knew if it would be locked up or not.
5. Should I get the extended warranty? I'm usually
against them, but I am expecting this computer to
last me at least 3 years (for $1300 it better!)
before I upgrade, as I got that much out of a Dell
and from what I understand, Mac's do not age nearly
as fast as Windows pc's.
It is well worth the cost. Never know what might happen. Also
it is good insurance for future upgrades. I traded in my G4 tower
purchased two years ago for 75% of what I paid for it. Apple care
transfers, giving the buyer the remainder of your warranty.
Thank you for any help,
-Evan

Testing of SAP BW system after migration from OS Unix to windows

Can I use Oracle app server with mysql

Can I use Oracle app server with mysql. I seem to have the following error when trying to create a datastore. I have mysql.jar in my classpath. Can any one tell me what's wrong.
Error initializing data-source 'jdbc/topup': DriverManagerDataSource driver 'org.gjt.mm.mysql.Driver' not found

Yes you can forward requests from your own apache to the iAS. This can be done using mod_proxy. Some hints about how to do this are availlable on this forum.
mod_oc4j is not a standard apache module, and therefore is not availlable when you download apache. There is no apparent reason to use mod_oc4j on a "regular" webserver (unless you want to build your own iAS). Also there might be some licenseing issues with using mod_oc4j module on a standard apache.
You can encrypt data that is passed from a random Apache to you iAS.

Whether using Oracle after migrating from MySQL be easy or not?
