On Windows: java.io.tmpdir:[C:\DOCUME~1\joshua\LOCALS~1\Temp\]
On Solaris: java.io.tmpdir:[/var/tmp/]
On Linux: java.io.tmpdir: [/tmp]
On Mac OS X: java.io.tmpdir: [/tmp]

The default temporary-file directory is specified by the system property java.io.tmpdir. On UNIX systems the default value of this property is typically "/tmp" or "/var/tmp"; on Microsoft Windows systems it is typically "c:\temp". A different value may be given to this system property when the Java virtual machine is invoked, but programmatic changes to this property are not guaranteed to have any effect upon the the temporary directory used by this method.

To specify the java.io.tmpdir System property, you can invoke the JVM as follows:

java -Djava.io.tmpdir=/path/to/tmpdir

By default this value should come from the TMP environment variable on Windows systems

操作系统不同 这个系统属性所表示的目录也不同On Windows: java.io.tmpdir:[C:\DOCUME~1\joshua\LOCALS~1\Temp\]On Solaris: java.io.tmpdir:[/var/tmp/]On Linux: java.io.tmpdir: [/tmp]On Mac OS X: java.io.tmpdir:
今天突然收到报警短信,说是/磁盘空间使用超过阀值。经查看,发现是有很多异常的SQL,执行不了,导致一直在处理,产生了临时占用了/tmp磁盘空间。 由于 操作系统 的/tmp空间有限,需要进行参数修改,将 tmpdir 的值路径进行修改。 mysql> show variables like ' tmpdir '; +---------------+-------+ | Variable_name | Value | +---------------+-------+ | tmpdir | /tmp | +---------------+-------+ 1 row in set (0.00 sec
