Checking the version of Oracle running on a UNIX system is a common task for system administrators and DBAs. There are several ways to accomplish this task, each with its own advantages and disadvantages.
One common method is to use the `sqlplus` command. To do this, open a terminal window and type the following command:
sqlplus
Once you are connected to the database, you can type the following command to check the version of Oracle:
select * from v$version;
This will return a list of information about the Oracle version, including the release number, edition, and patch level.Another method for checking the Oracle version is to use the `srvctl` command. This command is only available on Oracle RAC systems. To use this command, open a terminal window and type the following command:
srvctl config database -d
This will return a list of information about the database, including the Oracle version.Finally, you can also check the Oracle version by looking at the Oracle home directory. The Oracle home directory is the directory where the Oracle software is installed. To find the Oracle home directory, open a terminal window and type the following command:
find / -type d -name “oracle”
This will return a list of all directories named “oracle” on the system. The Oracle home directory will be the one that contains the `bin` directory. Once you have found the Oracle home directory, you can check the version of Oracle by looking at the `version.txt` file. This file is located in the Oracle home directory.
