How do I clear out the measure data in a 10g cube?

Does anyone know of an OLAP feature that I could call to zero out the measures stored in the cube before I refresh from the source data?
I'm new to Oracle OLAP, but I have some experience with Essbase and I have quite a bit of experience with Oracle PL/SQL. The database is 10g.
Here's my problem. My dimensions and cube are mapped to Oracle tables. I've built an Oracle procedure, using DBMS_LOB / xml_clob functionality, to refresh my cube. The procedure worked successfully to initially load the data. It works successfully when changing the dollar amounts in source data. But it's possible that a record in my source data can be totally removed. When this happens, the dollars from the removed record are still showing up in the cube total after the procedure executes. I had assumed the CleanMeasures="true" parameter would take care of this, but it is not.
thanks,
Nancy
Here's the parameters I'm passing to BuildDatabase in my Oracle procedure:
' <BuildDatabase Id="Action2" AWName="BUDGET.BUDGETS" BuildType="EXECUTE"
RunSolve="true" CleanMeasures="true" CleanAttrs="true" CleanDim="true"
TrackStatus="false" MaxJobQueues="0">';

If you are doing a reload every time then you can issue following commands to clear data from cube.
lmt name to all
allstat
clear all from <cubename>prttopvar
You can wrap above commands in pl sql procedure using dbms_aw.execute package and execute it before cube load starts. Instead of clearing it from whole cube you can clear only from one partition also. Just take a look at clear command in olap DML 10.2 reference.
Thanks,

I entered the incorrect password for my home wifi network and now I can't change it. How do I clear out the wrong password so that I can enter a correct one?

I entered the incorrect password for my home wifi network, and now I can't change it. How do I clear out the wrong password so that I can enter a correct one?

Settings > wi-fi then tap on the little blue arrow next to the network you want to change. You have to tap on the blue arrow and not on the name.
Now at the top tap on "forget this network".
After that, the iPhone will think your home network is a new network and will ask you for the password to connect.

How do I clear out the list of choices from the down arrow in the navigation? Can't find anything that tells one how to empty it

When you add a new tab, one can go to the navigation bar and click on the down arrow and get a choice of previous sites. I want to EMPTY that list. I cant out how to do it.

Entries in the location bar drop down list with a yellow (blue on Mac) star at the right end are bookmarks. 
You can remove such a bookmarked item that shows in the list if you open that url in a tab and click the yellow star in the location bar. 
This will open the "Edit This Bookmark" dialog and you can click the Remove button to remove the bookmark if you want to remove such a bookmarked entry.

How can I clear out the "other" space on my startup disk?

My startup disk is full as well, but I am barely using any space on my computer at all for files. I have also only had this laptop for about 9 months. I have been emptying my trash, clearing my dowloads, deleting anything I can to get more space, but its not helping because I barely have anything left to delete. I just looked into my storage space following the Lion's Storage Display steps, and this is what it looks like.
I have no idea what to do, but I can barely use anything on my Macbook Pro without it telling me I'm out of space.

To figure out what is filling the disk, the pane with "other" on it is about worthless.
I find it much better to use OmniDiskSweeper instead. It will tell the the folders and files that are using the most disk space so that you can intelligently decide what is causing the problem.

How do I clear out the messages storage content?

When I look under storage I see 1.1 gig set for messages / deleted messages. How do I free up this used and allocated space?

You would need to go to your Messages app and delete the conversations that you have had in the past that are no longer needed on your iPhone.

APPLE CARE - How do I find out the date of purchase of my mac?

Can anyone point out how do I find out the exact date of purchase of my mac? I would like to purchase the apple care extended warranty and I do not recall the exact date of purchase of my mac...just before or after a full year...? Can I look it up anywhere?
Many thanks in advance for your help.
Max

You can go to this site,
https://selfsolve.apple.com/GetWarranty.do
it tells you when your warranty expires which is 1 year after you purchased it, thats possibly the easiest way, but if you bought it from a store it may be different as it may be the date they purchased it.
With the extension program, if i purchase one now, my MBP was purchased april last year, will the extended warranty ad onto the date i purchase the extension program or from april last year when i purchased the mbp? I'm wondering because if purchase it now that effectively makes it covered for warranty for up to 4 years!

Clearing out old process data

How can I clear out old process data? In my test environment, I have several hung tasks that will not terminate. The tasks exist, but the process they were associated with no longer do.

There was a bug in 8.0 that I believe is fixed in 8.2 where tasks assigned to a group were not removed when the process was terminated.
Your easiest solution right now is:
- create a dummy local user called "dummy" or something like that
- go into adminui/process management/task management, find the tasks, and allocate them to the dummy user.
They will still be there, but at least they won't irritate anyone.

How can I find out the date of a movie I am trying to pre-order if the date is not available/showing in the "manage pre-order" section?

Thanks so much for your reply King_Penguin. No, sadly there is not indication of the expected release date on the film, it's no where to be found. I have also tried to look in other places online, but no luck. I guess your latter statement jives more with my situation, that being the studio/rights-holder hasn't feel inclined to provide the date.
