Data Guard Oracle 11g - oracle

I want to do the disaster recovery in oracle 11g using data guard. But I don't the procedure or the way how to do it. I want all of someone that show me the document or the way to do it.
Can anyone help me to do that?
Thanks,
Ung Sopolin

You could start with the Data Guard Concepts and Administration guide which covers the overall mechanism of Data Guard and the way to implement it.

This is a link to a data guard installation in oracle 9i. Besides some new feautures on 10g and 11g is should in essence be the same.

I'm currently trying to migrate a large table from cassandra to oraclesql and can't find many solutions

I've been researching and looking for ideas but the only thing close to a solution i've found has been where someone used pyspark to convert an oracle table into hdfs and then from hdfs into cassandra but I was hoping there was another/a clear solution to this data migration.
Title suggests that it is Cassandra > Oracle. Message text says Oracle > HDFS > Cassandra (i.e. the opposite direction). What exactly are you trying to do?
Suppose it is the title that is correct. If there's no tool which would do the migration for you, from my - developer's - point of view, creating a database link in my Oracle schema which points to Cassandra might be a good option. Then I'd just write some SQL code to migrate data I need. Here's how: Access Cassandra Data as a Remote Oracle Database.
Shortly:
connect to Cassandra as an ODBC data source
set connection properties for compatibility with Oracle
configure the ODBC gateway, Oracle Net and Oracle database
write queries

How to move OCI-classic to OCI

I have been using OCI-classic. And I'd like to move OCI-classic to OCI.
So I'd be greatly appreciated if you could tell me about below.
Support limitation of OCI-classic
Sample of migration from OCI-classic to OCI
If you can do, tell me the URL too.
Thanks.
There are different migration tools responsible for this, but at the same time, there are considerations you should make before migration to OCI, what kind of services you will migrate, compute,storage, and other services. It would help if you mapped before doing anything.
I highly recommended reading this documentation from Oracle to take a brief about the migration here
OCI-classic is a single tenant offering from Oracle Cloud with limited support. With the multitenant cloud premise available on OCI, it is best to move to OCI . There are lots of interconnected services on OCI which can help lift and shift but it also needs oracle devops help. I would suggest to reach out to Oracle support using SR and they can guide further based on your environment.

MS Access to Oracle database

I am developing an ASP.net application with Access database. I need to convert this Access database to Oracle. How can I do that?
I saw two options
Migrating the access database to Oracle through MIGRATION WIZARD in SQL developer
In Oracle, just creating a new connection with existing MS Access database and then converting to oracle.
Kindly let me know the best solution for this
thanks in advance,
Arjun
The two choices you proffer could be rewritten like this:
Use an automated tool written by experts
Do it the hard way and figure it out for myself
This is a personal, even philosophical, choice. Do you need to get the task done quickly? Or do you want to learn something along the way?
TRY IT and then tell us.
My experience integrating all things oracle with all things microsoft has always been complicated, and a lot of manual intervention was required.
It also depends on the complexity of your existing access database, if it's only one table, then you can grab that table sql, correct it for nvarchar -> varchar2 fields and datapump the data into oracle.
If Access has 1000+ tables I would suggest getting a professional to do it. Any reasonable dba should handle it no problem.
Please check the solution at Insert into from ms access to oracle db
You can customize the code based on your requirement. You can bundle the whole code into one class and prepare it as exe application.

Oracle Audit - DDL/DML not on. System Events on. How to turn all on?

Afternoon everyone,
I currently have a Oracle DB issue. I have Oracle Auditing on (AUDIT_TRAIL set to db). However the only information being captured is the System Events (log on, off).
From the Oracle 10g2 documenation (http://www.oracle-base.com/articles/10g/Auditing_10gR2.php) I notice that there are 3 audit options, however I cannot figure out how to turn the other 2 on.
Does anyone know how?
I don't know the answer to your question, but I know that the link you describe as "the Oracle documentation" is a third-party advice site. This is the Oracle 10g documentation. Specifically, here is the documentation on auditing. There you will find the answers you seek (at least I assume you will).
