CentOS or Oracle Linux for Oracle RDBMS?

Question

Oracle

The question arose - which of the listed systems should be used to deploy the Oracle DBMS? I know about the first one that it is based on the RHEL codebase, I don’t know anything about the second - neither how are they with updates, nor about whether it’s worth contacting at all. There are fears that sooner or later Oracle will not withstand the competition and close the project.

Answer 1

"The same eggs, only in profile" (c)
There is not much difference: when using CentOS, you will have to install about a dozen packages and tweak several system configs. In the case of OracleLinux, everything has already been done, just adjust these configs to your system parameters. I see the only plus in using OracleLinux only in the initial sharpening for this DBMS. But in the work this "sharpening" is not particularly manifested. OracleLinxu, like CentOS, is based on RHEL, everything is fully compatible, from packages to configuration file paths. Regarding the fear - it's you in vain, they won't close it.

Answer 2

some nonsense they wrote, how can oracle close its main project on which it cuts the most dough?
oracle package base from rkhela, they make their own kernel

Answer 3

Do you see the difference? OEL has its own kernels (supermicro does not start with them because of the raid module), but besides them, OEL also contains RHEL kernels. Otherwise they are both package and binary compatible. One system can be converted to another by simply installing another repository. OEL's only convenience for installing a DBMS is the oracle-validated package in the repository, which installs yum to download all oracle dependencies. But no one forbids you to install this package on centos or rhel. having downloaded it in advance, you will get the same effect. So this is "one field of berries", and you will not notice the difference in operation. Oracle even left the redhat-release file, for compatibility, left an example with OEL:
# cat /etc/oracle-release
Oracle Linux Server release 5.9
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.9 (Tikanga)
# cat /etc/enterprise-release
Enterprise Linux Enterprise Linux Server release 5.9 (Carthage)

Answer 4

Under Oracle, it's best to use what they recommend, which is Oracle Linux. At least out of the box you get a small OS tuning for this DBMS.
You will not receive any special benefits by installing CentOS in this case.
