Get est time for sql without running against the db ??? possible ?

hello,
is there anyways to get a query execution time without running that against the database ?? even an estimate would be good...i am on 10.2.0.3 ......i am it might be impossible for it...but anyways to get estimate besides setting autotrace only ?? as i said want nothing but just like a estimate time for how long will it take to finish the query...i know we can very long_ops view but as i said..without running against the DB ...is that possible ?? as the explain plan i get shows time ?? but is that how long it will take to finish up or ?/
select * from table(dbms_xplan.display);

How long is a string?
How deep is a hole?
How long does it take to read an unknown number of blocks containing an unknown number of rows from an unknown disk system with an unknown contention load, pulling it across an network of unknown bandwidth and unknown load ....
And I'm not saying that if you somehow provide all this that the answer can be known. I'm saying the too much of the information tht would be needed to make such an estimate is unknowable. Much of it will be widely variable from one execution of the query to the next execution of the exact same query. Which leaves you with exactly what to base your estimate on?
Without even seeing your query, I can tell you with absolute certainty that it will take between 1 nano-second and 100 years to execute.

SQL Tuning Advisor is run on statements and not sessions. I don't do much with SQL Tuning Advisor, but I'd consider that current running sessions a lost cause until it completes or you kill it. You can see the "estimate" of how long that current running SQL is going to take in v$session_longops. You can use a script like Tanel's sw.sql
http://blog.tanelpoder.com/2008/01/08/updated-session-wait-script/
to see what the wait interface has to say.

My approach for this would be to determine what the current explain plan is and compare it to one that ran (correctly) in the past and then try to determine why it changed. (bad stats, dropped index, parameter changes, etc).

Can I Update Time Machine Backup Without Booting From The Source Drive

Greetings,
Can I update a time machine backup without booting from the original source drive?
My main Macbook Pro internal drive seemed to have died. I had not backed up in months so my Time Machine backup was old.
I replaced the drive with a new one and settled for restoring from the old TM backup because my latest info was on the dead drive and not backed up.
I just plugged the "broken" drive into a dock and it mounted.
It won't boot from the drive but I can mount it and copy from it so far.
I now want to update my Time Machine backup with the info on the 'broken" drive while it's able to be mounted.
How can I accomplish this without booting from the 'broken" drive and running time machine.
Recap...
I need to update a Time Machine backup using another hard drive without booting from the source (as I cannot). Both drives are connected via USB to my MBP and I am booted from another MBP. I want to end up with the newer info from the "broken" drive updating my older Time Machine backup.
Thank You,
SG

Hi
Time Machine will only be able to backup whilst booted into OSX, so unless you can mount the drive, and boot up the OS that is installed on the disk, then no, you will not be able to run a Time Machine backup of that drive.
You could image the drive onto another using Disk Utility

Hi there,
You're running an old version of Safari. Before troubleshooting, try updating it to the latest version: 6.0. You can do this by clicking the Apple logo in the top left, then clicking Software update.
You can also update to the latest version of OS X, 10.8 Mountain Lion, from the Mac App Store for $19.99, which will automatically install Safari 6 as well, but this isn't essential, only reccomended.
Thanks, let me know if the update helps,
Nathan

Ensure 1 Active Sync process runs against the change log before all others?

He folks,
We have a lot of LDAP active sync thread. We have a primary on that correlates to an individuals account. Then we have several that represent affiliations at our organization. The affiliations are represented in LDAP as subordinates of the main persons entry. These sets of data were set up as different resource adapters because the they are different object types in LDAP.
Now we are running into a problem where the active sync threads for subordinates are running before the thread for the main entry. What this means, is that an affiliation thread might run, see a new person was added and ignore it (since that isn't it's resource) but find the affiliation subordinate entry and want to process it. However, the thread can't find an associated account in IDM yet, so no processing takes place on that change, ever..
If the main account active sync thread had already run, it would see the main entry, and then make a correisponding IDM entry. If the IDM entry has been made, and the affiliation resource active sync adapter runs, it will then find the IDM entry and update that.
So.. We are experience problems when the affiliation processes a new account before the main account sync process.
Can we ensure somehow that the main account active sync process always runs first? These are all LDAP resources. If we could ensure the main account resource / sync happens before any other affiliation resource, then we would never ignore data, and would not have anyproblems.
Does anyone know of a good clean way to do this?
Thanks!

I had a similar issue, and solved it by using post process workflows and starting and stopping resource adapters manually. This will allow you to start the first resource, and any others you want can be started/stopped manually via the workflow. You can effectively "chain" resource adapters to run in any order you'd like.
On the first resource that you want to run before anything else, this will run as a post-process workflow:
     <Activity id='0' name='stopFirstResource'>
        <Action id='0' name='stop'>
          <expression>
            <block name='stop'>
              <invoke name='stopActiveSyncOnResource' class='com.waveset.session.SessionUtil'>
                <ref>displaySession</ref>
                <s>%%FIRSTRESOURCENAME%%</s>
              </invoke>
            </block>
          </expression>
        </Action>
        <Transition to='Process Errors'>
          <ref>WF_ACTION_ERROR</ref>
        </Transition>
        <Transition to='startSecondResource'/>
      </Activity>
      <Activity id='1' name='startSecondResource'>
        <Action id='0' name='start'>
          <expression>
            <invoke name='startActiveSyncOnResource' class='com.waveset.session.SessionUtil'>
              <ref>displaySession</ref>
              <s>%%SECONDRESOURCENAME%%</s>
            </invoke>
          </expression>
        </Action>
        <Transition to='Process Errors'>
          <ref>WF_ACTION_ERROR</ref>
        </Transition>
        <Transition to='end'/>
      </Activity>
This will stop the first one (after it has run) and start the second one.
Then, on the post process workflow of the second resource:
      <Activity id='1' name='stopSecondResource'>
        <Action id='0' name='stop'>
          <expression>
            <block name='start'>
              <invoke name='stopActiveSyncOnResource' class='com.waveset.session.SessionUtil'>
                <ref>displaySession</ref>
                <s>%%SECONDRESOURCENAME%%</s>
              </invoke>
            </block>
          </expression>
        </Action>
        <Transition to='Process Errors'>
          <ref>WF_ACTION_ERROR</ref>
        </Transition>
        <Transition to='end'/>
      </Activity>This stops the second one.

My iphone 4 locked up for several hours. i then tried to reset by holding down the home button and power button at the same time for 10 seconds and then the home button for 10 seconds. it is now completely black. what do i do? couldnt restore it in iTunes

My iphone 4 locked up for several hours. i then tried to reset by holding down the home button and power button at the same time for 10 seconds and then the home button for 10 seconds. it is now completely black. what do i do? couldnt restore it in iTunes. Has anyone had this problem? Help!

Same thing happened to me today. I wasn't even using the phone for the past 6 hours and suddenly I can't connect to the internet, none of my internet apps would work - nothing. I tried to call AT&T from the iphone and it locked up - couldn't turn it off, change to the home screen - nada - brick.
Did the Home/Power button thing and that worked but this I've only had this phone for about 4 weeks and it's locked up more times than my 3GS did the whole two years I had it! Ridiculous

HT1349 my home button will not work properly... I have to hold it down several times for it to go to the home screen

my home button will not work properly... I have to hold it down several times for it to go to the home screen

I would try a restore just to see if it could be something software related, but if that doesn't work I would recommend taking to an Apple Store to see if it is a serious hardware issue and if it is, assuming you're in warranty, then they would be able to replace your phone.

Significant difference in response times for same query running on Windows client vs database server

I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
Ideally I would like to get a response time equivalent on the Windows client to what I get when running this on the database server.
In both cases the query plans are the same.
The query and plan is shown below :
{code}
SQL> explain plan
2 set statement_id = 'SLOW'
3 for
4 SELECT DISTINCT /*+ FIRST_ROWS(503) */ objecttype.id_object
5 FROM documents objecttype WHERE objecttype.id_type_definition = 'duotA9'
6 ;
Explained.
SQL> select * from table(dbms_xplan.display('PLAN_TABLE','SLOW','TYPICAL'));
PLAN_TABLE_OUTPUT
| Id | Operation          | Name      | Rows | Bytes |TempSpc| Cost (%CPU)|
|   0 | SELECT STATEMENT   |           | 2852K|    46M|       | 69851   (1)|
|   1 | HASH UNIQUE       |           | 2852K|    46M|   153M| 69851   (1)|
|* 2 |   TABLE ACCESS FULL| DOCUMENTS | 2852K|    46M|       | 54063   (1)|
{code}
Are there are configuration changes that can be done on the Oracle client or database to improve the response times for the query when it is running from the client?
The version on the database server is 10.2.0.1.0
The version of the oracle client is also 10.2.0.1.0
I am happy to provide any further information if required.
Thank you in advance.

I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
There are NO queries that 'run' on a client. Queries ALWAYS run within the database server.
A client can choose when to FETCH query results. In sql developer (or toad) I can choose to get 10 rows at a time. Until I choose to get the next set of 10 rows NO rows will be returned from the server to the client; That query might NEVER complete.
You may get the same results depending on the client you are using. Post your question in a forum for whatever client you are using.

How to get remaining time for baton after setting timeOut property

Hello,
Is it possible to get the remaining time for baton after setting timeOut, or do I have to maintain a separate Timer for that?
Been following this excellent tutorial here http://tv.adobe.com/watch/adc-presents/create-shared-forms-in-livecycle-collaboration-serv ice/

Thanks Nigel, before reading your reply, I came up with something like this, but it seems extending the Baton class is not enough, as I would need my own BatonProperty as well that uses this extended Baton class...
Also attempted to get some help here http://stackoverflow.com/questions/7116814/actionscript3-lccs-how-to-access-property-paren t-class-protected-var/7116882#7116882
Could this be made into a feature request for Baton and BatonProperty, se we could easily get the remaining time please? I guess I can wait for a future release.
/custom as file /

          super();

          trace("CURRENT TIMER:"+_autoPutDownTimer.currentCount);
