Database synchronization api

Is there a java api that I could use to easily synchronize two MySQL databases?

MySQL tools would be a better idea.
%Well, yeah, but I'm in the need of something that I can use to do the sync programmatically. Oh well, I'll come up with a solution...

Database synchronization with MySQL

Hi,
I'm connecting my ADFbc to a MySQL database v5.6; However, I can't seem to find the option that allows me to synchronize my entities to the changes made on the database tables. I am using JDeveloper 12c.
Is the database synchronization option only available for an Oracle database connection?
Imad.

Imad,
database synchronization is available.

Oracle Database Lite API Specification JDBC

Hello.
I would like to create a schema with Oracle Database Lite API Specification.
I have done a script to create an application in the Mobile Server in this way:
"Platform p = new Platform("WINCE_ARMV4_US_OLITE_STD42");"
"Application app = new Application(nombre_app, ruta_virtual_app, p);"
And using ConsolidatorManager for the conection:
"ConsolidatorManager cm = new ConsolidatorManager();"
"cm.openConnection(user, password, dir_repository);"
But after that, I can't get the application. Could you help me, please?
Thank you.
With best regards.

Is this subscription parameter causing a problem?
unless the subscription parameter name is referenced in the select statements for any of the publication item definitions, it will be ignored by the processing as the subsetting parameters are just used to supply values for bind variables at query time
If you have other valid subsetting parameters for the user, then try (if all your set up is done via APIs and you do not have an APPLICATION, only a PUBLICATION, this may not work)
1) go into the mobile manager > users
2) search for user name, and click on the link under the user name
3) go to subsetting parameters and pick a valid one
4) select the data and do cntrl C cntrl V (cut and paste)
5) press the save button
The above has the effect of resetting the user account, and refreshes sequence values, c$all_client_items etc.
If you can do the above steps, but this does not remove the subsetting variable, you should be able to go to it and set the value to NULL
I do not think that there is a delete function due to the dependancy to the select statements which would be complex to validate

Advanced Queueing and databases synchronization

What kind of (application) problems could be solved by Advanced Queueing ?
What about databases synchronization ( two Oracle Database Standard Edition One ) ?
TANK YOU !

AQ is intended for messaging. Messaging between applications, messaging between back-end and front-end.
Synchronization would be a poor use of messaging. If you want synchronization then name your version number (all four places) and replication technology and we can point you in the right direction.
For most situations I use:
DBMS_RECTIFIER_DIFF or DBMS_COMPARISON

SSAS database synchronization is slow

Hi,
I'm testing the SSAS database synchronization function.
and I found it slow!!!
my server is able to write at 400MB/sec and more, but SSAS is only able to write at 60MB/sec.
I'm testing copying the olap database from 2 instances on the same server, so not have the network involved.
is there any option available around the synchronization process? excepts the compression one.
at the olap service itself? in the config file, is there any config around disk cache for this sync process or something like this?
thanks.
Jerome.

Hi Jerome,
According to your description, you copy the OLAP database from one instance to another instance on the same server, you need to know why SSAS is only able to write at 60MB/sec on the server which is able to write at 400MB/sec and more, right?
Based on my research, synchronization's file copy phase is single-threaded. And due to the single-threaded file copy phase, synchronization might not be the most efficient way of transferring files. So in your scenario, SSAS is only able to write at 60MB/sec
on the server which is able to write at 400MB/sec and more. Here are some blogs about synchronization internal and synchronization performance troubleshooting, please see:

ESSO-database synchronization.

Hi all,
I'm newbie to Oracle Enterprise Single Sign On.
I need to do database synchronization with ESSO.
I'm using Oracle Database 11.1.0.
Can anyone please share a link or document describing the steps to be followed for database synchronization with ESSO?
Thanks in advance.
Regards,
Swathi.

Hi Rivey,
Thanks a lot for your reply.
I'm able to synchronize oracle database with ESSO i.e,I'm able to login to oracle database directly without giving credentials.
But when I try to extend the schema to Oracle Database I'm getting the following database error :
ORA-12514 : TNS :Listener does not currently know of service requested in current descriptor.
Thanks & Regards,
Swathi.

About the new optional Database related API for CLDC

Hi friends...
As i know there are different optional Java ME API's for the CDC toolkit but for implementing the sql in the J2me programming using the CLDC toolkit
is there any JDBC optional API by Sun Microsystems?
such as sql for the CDC please tell me that
please tell me api besides the RMS(Record Management Systems)

Yes, .Net framework is supported. Basically any programming is still supported and that doesn't really change. MDW will work exactly the same. The biggest difference between the two databases is Oracle Lite works well will Oracle SQL but SQLite is only SQL92 compatible (but can't handle right outer join... I think. So, you would have to modify SQL for this. Not that hard to do.) Berkeley DB/SQLite doesn't support stored procedures... but you can code your own functions and procedures before building the Berkeley DB library and they work the same way. I am playing with this feature now. Synchronization will work exactly the same way, so you don't have to change your knowledge of the Mobile Server. If you currently have a WinCE Oracle Lite deployment, all you have to do for sync is change the platform to Window Mobile SQLite... I know Oracle Support is working on a document note on how to extend platform support. I have posted an article on working with Berkeley DB.
http://www.rekounas.org/2010/08/26/getting-started-with-berkeley-db-and-oracle-mobile-server/
I have also ramped up the number of posts I have been creating due to this announcement. BTW, I am not Oracle, I am an independent consultant that has worked on many Oracle Lite and Mobile Server projects. Overall, this is exciting news and I do like the direction, but I do have a soft spot for Oracle Lite. I thought it was a fantastic product that was very powerful for a small database, but with so many features, the footprint was just too large and ultimately why the decision was made to go with BDB. I will find out if I can post the presentation that I did last week as it does give good insight on what Oracle is doing.

TP4 ADF BC [BUG] view link are not updated after database synchronization

I have a table with a recursive relationship.
By mystake, I created a recursive foreign key for the same attribute (deptid->deptid instead of deptid->parentdeptid).
I generated entity, view and application module from this schema.
When compiling, errors was produced indicating the problem.
I corrected the problem in offline database, generate the changes into the database successfully.
I ask to synchronize the entity with the database, the changes was identified correctly and a new association was created.
First remark: the old one still there and it was necessary to delete it and rename the new generated one (to be consistent with other name). May be an option to overwriting the old one will be more pleasant, may be asking if the new one has to replace an existing one and show a list of existing ones.
Regenerating the association was correct and one error was removed when compiling again. The error on the view link still there.
I would like to delete the assoc and recreate it from the entity assoc but it was not possible easily because the view link is used in the application module !!!!
It will be nice to permit to regenerate an existing view link from an entity association without deleting it.
May be it is a better way to synchronize ? I would be very interesting to know how to achieve it as the best !

Was the inability to have the synchronization remove the key specific to the existing association's being self-referential, or if your initial association was from DeptId to some other attribute (which you then corrected) would the synchronize have fixed the problem?
The simplest way to achieve what you want given existing features would be to have delete the view link instance, view link, and association, follow by resynchronizing (I believe), then recreating the viewlink and adding back the view link instance.

Rman Duplicate database synchronization problem

I beleive... and correct me if I'm wrong, but the duplicate command will open the db created with RESET LOGS. Thereby meaning you can't use the archive logs.

Database connection - API layer?

I'm just doing a quote for a job, and the potential client has sent me over a 20 page document produced by someone else quoting, with a very detailed scope of the project.
Way more detailed and flowery than anything I would do, but just wanted to ask about one thing.
Its a database site, and will use mySQL for that.
In the document it has a little diagram referencing:
- the solution (i.e. the website I guess)
- the database
And between the two, an API Layer.
To me, all that really happens is that a connection file is created which connects the site to the database using a bit of PHP.
Am I missing something, not doing more than I maybe should be doing, or is this just a typical way of presenting something that looks a bit more techie and involved than it perhaps is?
Any comments welcome! Thanks.

I had a look on Google, and found some stuff on database abstraction layers, which I must admit is a new one on me.
Is this something that people would recommend doing as a matter of course, or something that would be surplus to requirements most of the time?

Duplicate database synchronize

I have duplicated the database “prod” to “dup”.
$rman target sys/oracle@ORIGDB auxiliary /
RMAN> duplicate target database to DUP nofilenamecheck;
My question is in order to synchronize the duplicate database from time to time, do I need to drop the duplicate database first and then re-run the “RMAN> duplicate target database to DUP;” command?

You don't have to drop the database first.
Shutdown and then start in nomount before you run the duplicate command.

The cause of the problem is probably a shutdown of the secondary server. After the server start, it tried to synchronize with the primary server. Later a few days, the synchronization process failed, unable to find the restore point. However, ORACLE process took more than 99% of CPU. What should I do to solve this problem? Could anyone tell me the what I need to proceed. Thank you in advance.

Database Synchronization.

Hi guys,
I have 2 different database systems. The Oracle database located at head office and the MySQL Server located at the clients place. I want to know is there any possibilities:
To automatically update the Oracle Server if the MySQL server is updated, on daily basis (or is synchronization possible). I am working on this project. Help on this will be greatly appreciated.
Thanks in advance.

Can ODBC direct connectivity using Oracle Call Interface (OCI) or JDBC be also used for this purpose?I'm not sure what you mean by "ODBC direct connectivity using Oracle Call Interface (OCI)". OCI only allows you to connect to an Oracle database from a C/C++ program. ODBC drivers for Oracle are generally implemented using OCI. But I'm not sure what that buys you. You can, of course, write an application that connects to both Oracle and MySQL, reads from MySQL, and writes to Oracle, but then you're copying the data over the network twice and you have another moving part to keep track of.
You could potentially load the MySQL JDBC driver into the Oracle database and write a Java stored procedure that connects to MySQL. But that's much less functional that using the Transparent Gateway for ODBC since you would have to write JDBC code to access the MySQL database rather than just using SQL.

Generating Database Documentation API?

Generating Database Documentation is a new feature in 1.5.1. It is explain here:http://www.oracle.com/technology/oramag/oracle/08-sep/o58sql.html
I was wondering if they where an API version of this so i can call this straight from the database.

Hi,
When you select "Generate DB Doc" on a connection, SQL Developer runs a number of queries that aren't compatible with Oracle 9i.
For example, "NOCYCLE" and "ALL_IND_STATISTICS" used by the following queries are compatible only starting with Oracle 10g.
SELECT B.OBJECT_ID,
b.owner,
b.object_type,
b.object_name,
b.status,
replace(b.object_type,' ','_') type_link,
b.owner sdev_link_owner,
b.object_name sdev_link_name,
b.object_type sdev_link_type
FROM sys.all_objects a,
sys.all_objects b,
(SELECT object_id, referenced_object_id
FROM public_dependency
START WITH object_id = :OBJECT_ID
CONNECT BY <strong>NOCYCLE</strong> PRIOR referenced_object_id = object_id) c
WHERE a.object_id = c.object_id
AND b.object_id = c.referenced_object_id
AND a.owner NOT IN ('SYS', 'SYSTEM')
AND b.owner NOT IN ('SYS', 'SYSTEM')
AND a.object_name 'DUAL'
AND b.object_name 'DUAL';
select * from sys.<strong>all_ind_statistics</strong> where owner = :OBJECT_OWNER and index_name = :OBJECT_NAME

How to do database synchronization

Hi people,
if one database on 4 or 5 machines need to be synchronized after every 30 minutes.
what needs to be done for this?
like lotus notes one mail file created on local pc and one is on server and they synchronize after given time.
thanks,
