Hi All,

I have to change TSM "Schedule Randomization Percentage" to value of 10. Is there any other parameter i need to check or verify before changing this value from 25 to 10. If i change this, will it affect the normal functionality of the TSM server apart from randomizing the start time of the schedules. Need inputs on this. Whether it requires any reboot of the TSM.

Thanks

You can set this value at wish, without a server restart. Just issue
"SET RANDOMIZE 10" in the administrative commandline client ("dsmadmc").

Please note that the actual randomization window (the time across which the start time of a schedule gets scattered) is calculated individually per schedule based on the "DURATION" of that schedule, which is the total length of the time window where a schedule must have been started (not finished) to be considered "successful".

So if a schedule is defined with a default duration of 1 hour its actual start time will be scattered across a time window of 6 minutes with RANDOMIZE 10, whereas the start time of a schedule whose duration is let's say 5 hours gets spread across 30 minutes with the same RANDOMIZE setting.

Do you still remember this Q: http://www.experts-exchange.com/Storage/Backup_Restore/Q_26555844.html 
which you posted under your former account?

Is this issue solved?

If you can't use the other account any longer, you (or I) could ask a moderator to close it!
