Oracle Database Migration from Solaris to Linux Using Physical Standby

Key Highlights

• When you want to perform Solaris to Linux Oracle database migration, you need to check the source and destination databases and their versions to ensure the migration is possible because your source and destination are different.
• Use it for Data Guard.
• Configure the destination server for Data Guard.
• With heterogeneous migration, using a heterogeneous Data Guard makes the whole process easier.

When you decide to perform heterogeneous database migration, you may need to take some added steps unlike homogeneous database migration, which is straightforward. When you want to perform Solaris to Linux Oracle database migration, you need to check the source and destination databases and their versions to ensure the migration is possible because your source and destination are different.

Solaris to Linux database migration is possible for the following combinations:

• Source: Solaris x86-64 to destination: Linux x86-64, 11g plus and Solaris x86, 10g plus
• Source: Linux x86-64 to destination: Windows x86 and x86-64, 11g plus, Linux x86 and IA64, 10g plus, and Solaris x86-64, 11g plus
• Source: Solaris x86 to destination: Solaris x86-64, 10g plus

This combination can also be in the reverse direction. It means if you want to perform Oracle database migration from Solaris to Linux, then also for the same combination migration is possible.

It is also possible to set up a Data Guard between Solaris on AIX and Sparc on Power. In general, a majority of migrations are performed on Linux. It means migration from Solaris to Linux is more common.

Test before action

Instead of jumping directly to perform Solaris to Linux Oracle database migration, it is always recommended to test things. This can ensure that you can avoid bugs in the later stages. To perform testing, set up two servers. These servers will be used to evaluate the test results for Data Guard with disparity. You can set up the data guard with easy steps as mentioned hereunder:

• Configure the source server with Solaris 11 64-bit. Install oracle 12.2 on the server. Use it for Data Guard. This is the first process in Solaris to Linux migration.
• Configure the destination server for Data Guard. It will be a Linux 64-bit server with Oracle 12.2 installed on it.
• As we are focusing on migrating Solaris to Linux using physical standby, set up an RMAN duplicate from Solaris 11 to Linux.

Once you complete all these configurations, time to start managed recovery. As the whole process is reciprocal, the same configurations apply with changes in the source while performing Oracle database migration from Solaris to Linux.

While you are setting up servers and performing the required configurations, test the environment to ensure there is no unusual behavior or errors. If everything goes smoothly, you are ready to complete Solaris to Linux migration.

Conclusion

When performing Solaris to Linux Oracle database migration using a physical standby to eliminate or minimize downtime, we have used Oracle Data Guard. With heterogeneous migration, using a heterogeneous Data Guard makes the whole process easier. If you find it all overwhelming and want professionals to take over, take help from Princeton IT Services. The company has successfully performed several homogeneous and heterogeneous database migrations. They hold the required expertise to make this process swift, error-free, and accurate.
