Error code: ORA-00050

Official English explanation: “failed to acquire bootstrap lock”

Chinese explanation: 启动锁获取失败

Common cases:

• This error can occur when trying to start up an Oracle database and there is already an instance of the database running.
• The error can also occur if the database has crashed or if there was a forced shutdown of the database.

Resolution steps:

1. Identify the process that holds the bootstrap lock by using the following command:

perlCopy code
ps -ef | grep ora_smon

2. If the process is still running, end the process by using the following command:

bashCopy code
kill -9 <process_id>

3. Start the database again.

Note: If you are unable to identify the process that holds the bootstrap lock, or if ending the process does not resolve the error, then it may be necessary to restart the machine where the database is running.
