Generally speaking, we should regularly back up the important files (such as the configuration file under/etc), so as to avoid accidental deletion of important files in abnormal state such as drunk hands. However, if the accident really happens, and we do not make a backup, then try to manually recover it, the file recovery software used here is extundelete . 1. re-mount the partition as read-only state:This is the first step in recovering files and o

The recovery process consists of two information sources---backup files and binary logs, which can be restored to the state at the time the backup was performed, and the binary logs revert to the state when the failure occurred. The following describes how to use these two files to recover a database or to recover a single datasheet.

In my daily work, it is still very difficult to restore some nonstandard operations, such as drop, truncate, and delete, the drop operation is basically safe if recycle bin is enabled in Oracle. The delete operation can be performed using the flashback delete operation, which may cause some minor operations such as update and insert, you can use the flashback query to assist i
Panic is a built-in function, and when a function f calls panic,f execution stops, the deferred function call in F is executed, and then F returns to the caller who controls it. This process is performed along the call stack until all functions in the current goroutine are returned, and then the program crash. The panic occurs because of a run-time error called the Panic function (for example, array out-of-bounds access) recover is a built-in function
