How do I fragment a table so that it is distributed over multiple oracle 9i servers.
Oracle horizontal scability feature is called RAC (Real Application Clusters). It allows a cluster of servers to act as a single database. It is a share-everything architecture: all servers have access to the full database that resides on shared disks.
In other words, you wouldn't "fragment" a table accross multiple servers in Oracle. You can look into partitioning, which allows you to partition a table accross several tablespaces.
Partitioning is an Entreprise Edition feature, RAC is an option of the Entreprise Edition.

I have two virtual servers and I installed Oracle 19c on only one server, and I need to install another Oracle database on the second server and I need to make clustering in the database between the two servers. How to do this? Is this available using Windows Cluster?
You can not use windows cluster to deploy oracle RAC. You should oracle's own software (Oracle Cluster ware) to do it.
2.To deploy oracle RAC:
a.If you installed database as a single instance,at first you should convert it to RAC and then through oracle addnode procedure, add the second node to cluster.
b.If your installation is a RAC you should do the prerequisite on the second node and using oracle addnode script, add the second node. in recent versions of oracle addnode has a graphical interface also.
We have a physical standby database which is used only for running reports. It is not intended to be ever used as primary.
Now - a reporting database has much different requirements than an OLTP one.
I want to propose that we either convert this standby database from PHYSICAL to LOGICAL and create different database objects - especially INDEXES to support reporting.
What could be pros and cons of such approach ?
I am pretty new to Oracle Golden Gate, wanted to understand if it possible to create a bidirectional sync between Oracle 12x and Cassandra(DSE) using Oracle Golden Gate? Searched several places in internet but most examples are replicating data between Oracle databases. I started wondering if it is even possible to do so. Can anyone help me with any documentation?
There is a separate module called Oracle GoldenGate for BigData. It supports many NoSQL replication targets.
One of the supported BigData databases is also Apache Cassandra.
There is a separate manual explaining how to use it.
There is no separate module that allows you to connect Apache Cassandra as the source of your replication. If you need such replication you need to provide some intermediate step. The source of replication for Oracle GoldenGate can only be a database (Oracle, TimesTen, DB2, Informix, MySQL, MS SQL Server, NonStop SQL/MX, SAP/Sybase ASE, Teradata) or a JMS queue.
I am newer one on Oracle system. I am facing to a problem related Oracle database syncing.
We have 2 databases(A and B). Database A is synced to database B via Oracle GoldenGate. When too many records insert into database A, Oracle GoldenGate falls down.
Can you please suggest another solution for this issue ? We interest in physical hardware solutions if it is available.
Thank you.
Golden Gate is used for logical replication. Hardware replication is a physical kind of replication, like Oracle Data Guard. There will be a reason for the choice for logical replication. If not, go for Oracle Data Guard, which is very efficient and robust.
In the latest version of Oracle Database (11g Release 2), there's a new option called Real Application Clusters (RAC) One Node. What is "One Node", and how does it differ from regular RAC?
Mogens Norgaard used to joke about "single node RAC" but now it actually exists!
Basically, One Node is running a RAC database on a single server, rather than across a cluster of servers. There is an Oracle white paper on the topic. Find it here. The money quote is:
"Oracle RAC One Node enables:
• Better server consolidation
• Enhanced protection from failures
• Greater flexibility and workload management
• Better online maintenance
In addition it allows customers to virtualize database storage, standardize their database
environment, and, should the need arise, upgrade to a full multi-node Oracle RAC
database without downtime or disruption."
