DESCRIPTION
For most system errors, MySQL displays, in addition to an internal text message, the system error code in one of the following styles:
message ... (errno: #) message ... (Errcode: #) |
You can find out what the error code means by examining the documentation for your system or by using the perror utility.
perror prints a description for a system error code or for a storage engine (table handler) error code.
Invoke perror like this:
shell> perror [options] errorcode ... |
Example:
shell> perror 13 64 OS error code 13: Permission denied OS error code 64: Machine is not on the network |
To obtain the error message for a MySQL Cluster error code, invoke perror with the --ndb option:
shell> perror --ndb errorcode |
Note that the meaning of system error messages may be dependent on your operating system. A given error code may mean different things on different operating systems.
perror supports the following options.
