Description of deployment uard configurations between heterogeneous platforms and deployment uard configurations

Description of deployment uard configurations between heterogeneous platforms and deployment uard configurations
When deploying a replicuard, the simplest case is that the configurations of the master and slave nodes are identical. However, it may happen that a deployment is performed on a heterogeneous operating system, so that data migration between heterogeneous platforms can have minimal downtime or risks. It is also a comprehensive solution to reduce investment in disaster recovery by configuring heterogeneous processing capabilities or backup systems with low hardware costs. Use the description that provides this configuration to determine which platform combinations can configure Data Guard and whether any additional requirements or restrictions are applicable.

If you want to use a heterogeneous Master/Slave uard configuration, Oracle recommends that you perform a full test and ensure that the slave uard can implement normal switch between switchover and failover.

1. Determine the Platform ID of the Master/Slave database

SQL> select platform_id, platform_name from v $ database;

PLATFORM_ID PLATFORM_NAME
-------------------------------------------------------------------------------------------
13 Linux x86 64-bit


As long as the Oracle platform can be run on each authenticated server, the Oracle software installed is the same, and the Oracle database version and patch set are the same, the difference between the master server and the slave server is always supported.
Examples of the supported differences include:

• Hardware manufacturer (e.g. Dell and Sun or Hitachi and EMC)
• Hardware configuration (e.g. number of CPUs, amount of RAM, storage configuration, etc)
  
• Processor (e.g. x86-64 AMD64 and x86-64 Intel 64; POWER4 and POWER5)
  
• Operating system distribution (e.g. Red Hat Linux, SUSE Linux or Oracle Enterprise Linux)
• Operating system version (e.g. Windows 2000 and Windows XP)

The difference above can be considered as the same platform (PLATFORM_ID)


2. If the platform (PLATFORM_ID) of the master and slave databases is different, you can use the following table to check whether the physical backup uard can be configured between the two databases.


In addition to supporting the same platform configuration, the following table also shows that physical platform uard can be configured between different platforms, such as Linux x86-64 and Microsoft Windows (x86-64 ).

Summary:

We can also see that Oracle supports deployment of DataGuard between some heterogeneous platforms starting from Oracle 11g.
