Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

sleep - suspend execution for an interval
/usr/bin/sleep /usr/bin/sleep time ksh93 sleep time
/usr/bin/sleep sleep suspends execution for at least the integral number of seconds specified by time. ksh93 sleep suspends execution for at least the time in seconds specified by time or until a SIGALRM signal is received.
/usr/bin/sleep The following operands are supported for /usr/bin/sleep: time time in seconds can be specified as a non-negative decimal integer number. ksh93 The following operands are supported: time Specify time in seconds as a floating point number. The actual granularity depends on the underlying system, normally around 1 mil- lisecond.
Example 1 Suspending Command Execution The following example executes a command after a certain amount of time: example% (sleep 105; command)& Example 2 Executing a Command Every So Often The following example executes a command every so often: example% while true do command sleep 37 done
See environ(5) for descriptions of the following environment variables that affect the execution of sleep: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH.
The following exit values are returned: 0 The execution was successfully suspended for at least time seconds, or a SIGALRM signal was received (see NOTES). >0 An error has occurred.

If the sleep utility receives a SIGALRM signal, one of the following actions is taken: o Terminate normally with a zero exit status. o Effectively ignore the signal. The sleep utility takes the standard action for all other signals. SunOS 5.11 20 Nov 2007 sleep(1)
