Information about tablespace

i have window server and oracle 9i
and have three questions
firstly
when we create new tempfile
what is different between autoextend and reuse??
secondly
if i have a tempfile used now
what will happen if i create new one and drop the old one which is full and take over 10 gigabyte???
thirdly
when i check the temp tablespace space in my database i found the free space is zero
is there is a problem
what is a code to show the parameter value of tempfile i.e mazsize , next , size , reuse , autoextended
and what is the code to make it autoextended on and maxsize unlimited
i will solve it by create new tempfile
thanks to every one pass to this post

thanks to every one pass to this posti need help very importantYou asked for an explanation of concepts, which you were given. What do you need help with? We can't read your mind. As for "very important", this is a forum of volunteers.
BTW, free space = zero in a temp TS is normal. Extents are not dropped just be re-allocated. Instead they are marked 'available' and re-used. So if your un-named, un-described "important" problem that you need help with is simply that your temp TS has no freespace, then you have no problem as that is a normal and expected condition.

Informations about 'alter tablespace ... coalesce'

Hi,
I'm quite new relatively to the DBA functions. I have an Oracle 8i database on a RedHat Linux server.
I've examined my tablespaces and I found that many of my tablespaces have the pctincrease=0. In this case the process SMON don't join the adjacent free extents so I have a lot of free extents but only few of them are coalesced.
I thought to coalesce them with the command 'alter tablespace nametablespace coalesce', but I don't know very much this command. I'd like to know more informations about it, above all if I can launch it when my users are working on the database or if it's better to stop the listener and to do a backup before to launch it (among the tablespace that I need to coalesce I have also the Temp tablespace).
In other words: is the alter tablespace coalesce an harmless command or I need to take some precutions ? And Where I can find more informations about this command ?
Thanks
Marco

You can find more information about the command by reading the manual.
Coalescing tablespaces is a relatively harmless command. You can run it while users are on the system. They might experience a momentary slowdown, but probably not. All the command does is delete and update entries in an Oracle internal table (FET$ if anyone cares). Coalesce will do nothing if there are no adjacent blocks of free space to coalesce.
You do not want to coalesce the freespace in your temp tablespace. Oracle manages this internally, and it is more efficient to have a lot of fragments for temp. It saves a lot of recursive sql when a new extent is needed for a sort.
In the other tablespaces, if the blocks of free space are relatively large, then coalescing will not really gain anything. If your fragments are small, and your segments are frequently allocating new extents (which in itself is a problem), then you may gain a little performance by manually coalescing the tablespace. However, Oracle will coalesce free space if required to get enough space to allocate a new extent.
If you want to see if coalescing will do anything, you can use:
SELECT tablespace_name,file_id,block_id,block_id + blocks next_free
FROM dba_free_space
ORDER BY 1,2,3Then check if next_free in the previous row is the same as block_id in the current row.

Information about the default setup for the demo user

Hi,
Can anyone guide me the properties which we have to set for the below
# Information about the default setup for the demo user.
db.adminUser=system
db.demoUser=FOD
db.demoUser.password=fusion
db.demoUser.tablespace=USERS
db.demoUser.tempTablespace=TEMP
And what exactly they represent
Regards,
Krishna

Krishna,
It's pretty obvious...
db.adminUser = the username of a dba user in your database
db.demoUser = the username of the demo user that will get created
db.demoUser.password = the password that will be used for the demo user
db.demoUser.tablespace = the default tablespace for the demo user
db.demoUser.tempTablespace = the default temporary tablespace for the demo user
You don't have to change any of them.

How to get information about creation of a virtual machine on a Hyper-v host.

Hi,
How to get information about creation of a virtual machine on a Hyper-v host?
I need: host name, time created, creator user.
I saw in Hyper-V-VMMS but I found info about movements of VM between hosts.
Thank's in advance.
Denius Valiant

For Host Name * Created Time Use This Command In PowerShell
Get-VM -Name (Read-Host "Type Your Vm Name") |select CreationTime , ComputerName
and for Create User , As i know you should see on Event Log .
Go To Event Log Viewer--->Applications And Services Logs--->Microsoft--->Windows--->Hyper-V-VMMS--->Operational
You can see in Event Log who create the Vm.

A PDF document with information about activation for CS6 software

Here's a PDF document with information about activation for CS6 software.
I found it very useful for understanding how the system worked for activation of perpetual licenses, both in cases where the computer is and isn't connected to the Internet.

Ann, with some browsers, the PDF document will download in the background rather than appear in a browser window.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.
In particular, I am analyzing the example "Even Angle Reference Signal Processing (Digital Tacho, DAQmx).vi", whose documentation I am reproducing in the following:
DESCRIPTIONS:
This VI demonstrates how to extract even angle reference signals and remove the slow-roll errors. It uses DAQmx VIs to acquire sound or vibration signals and a digital tachometer signal. This VI includes a two-step process: acquire data at low rotational speed to extract even angle reference; use the even angle reference to remove the errors in the vibration signal acquired at normal operation.
INSTRUCTIONS:
1. Run the VI.
2. On the DAQ Configurations tab, specify the sample rate, samples per channel, device and channel configurations, and tachometer channel information.
NOTE: You need to use DSA PXI-447x/PXI-446x and PXI TIO device in a PXI chassis to run this example. The DSA device must be in slot 2 of the PXI chassis.
3. Switch to Extract Even Angle Reference tab. Specify the number of samples to acquire and the # of revs in reference which determines the number of samples in even angle reference. Click Start to take a one-shot data acquisition of the vibration and tachometer signals. After the acquisition, you can see the extracted even angle references in Even Angle Reference.
4. Switch to the Remove Slow-roll Errors tab. Click Start to acquire data continuously and view the compensate results. Click Stop in this tab to stop the acquisition.
ORDER ANALYSIS VIs USED IN THIS EXAMPLE:
1. SVL Scale Voltage to EU.vi
2. OAT Digital Tacho Process.vi
3. OAT Get Even Angle Reference.vi
4. OAT Convert to Even Angle Signal.vi
5. OAT Compensate Even Angle Signal.vi
My question is: How is the synchronization produced at the time of the compensation ? How is it possible to eliminate the errors in a synchronized fashion with respect to the surface of the shaft bearing in mind that I am acquired data at a low rotation speed in order to get the "even angle reference" and then I use it to remove the errors in the vibration signal acquired at normal operation. In this application both operations are made in different acquisitions, therefore the reference of the correction signal is lost. Is it simply compensated without synchronizing ?
Our application is based on FPGA and we need to clarity those aspects before implementing the procedure.
Solved!

How do I use my serial number to find information about my MacBook Pro's Processor and RAM?

So I want to find information about my MacBook Pro's processor and RAM using the serial number because the MacBook no longer works. I remember being able to find this information on the apple website before, maybe by using the coverage checker. Did they take this information out of the coverage checker? Is it no longer possible for a costumer to obtain this information?

Append the last three characters of it to http://www.everymac.com/ultimate-mac-lookup/?search_keywords= and load the page.
This won't reveal how much RAM it currently has installed.

Changing from dev to standard edition causes "Could not obtain information about Windows NT group/user error code 0x6e."

Hello,
We recently upgrade our SQL Server 2012 SP1 (64bit) dev edition to standard edition, after we purchased the required licence and it was deployed in production.
Since the edition change, we are now receiving the following error, with some of our jobs, which have an e-mail step in them, which is causing the jobs to fail.
Msg 14661,Level 16, State 1, Procedure sp_send_dbmail, Line 517
Query execution failed: Msg 15404, Level 16, State 19, Server BL-SVR15, Line 1
Could not obtain information about Windows NT group/user 'BLUELIZARD\savaa', error code 0x6e.
Any ideas how to fix this issue? We were also having a similar error, when executing the jobs, but changing the job owner to SA has fixed this issue.
Thanks,
Andy.

Hi,
Which user account you used for SQL Server service, domain account or local account?
If it is domain account, are you able to log in to a machine with it?
Make sure that the password of account is not expired.
Also, grant the user Allowed to Authenticate permission and see how it helps.
Refer to the below article:

Dear sap colleages
I need to know these information about an ASSET:
Purchased orders,
Items from purchase orders,
which of these items i've received, i've paid (also date), i've not paid ( amount of debt related to asset)
payments in advanced (date),
wich of these payments have been cleared (clearing date) and wich not,
who is the vendor,
other expenses (such as delivery)
the amount of taxes,
invoices related and NOT RELATED TO purchase order
payments without invoice
Which transactions do i need to follow?
or
Which document flow?
or
Which tables? Wich keys?
or
Is there a standard report that can give me such information?
Any documentation and/or code will be appreciated.
I need to program a report to integrate all these information.
Thanks and Kind Regards

Hi:
Regarding payments to vendors,refer to FBL1N - Display/Change Line Items .
Select the company code and then open items radio button and today date.It will show what are payments still to be paid to the vendor.If you select cleared items, it will show the payments paid to the vendor.If you select all items radio button, it will show all paid and unpaid payments to the vendor.
Check this report whether it fills your requirment.
When the user posts the business transaction, he has to input all the details, otherwise some of the information may be missing.
Please let me know if you need more information.
Assign points if useful.

ITunes Match unable to complete "Gathering information about your iTunes library."

All week I have been trying to get 2 separate iTunes accounts on 2 different Macbook on Air's both running iTunes 11.3.1(2) on Mavericks 10.9.5 - the progress bar crawls along and never actually reaches the end. Both iTunes Match accounts are completely empty (i.e. show zero media available on connected iOS devices). I have signed in and out of iTunes Match, deleted the libraries and re-added them etc. but the scan just isn't working.
So, is iTunes Match being discontinued ahead of the announcements on 9/9 or is this a temporary glitch, or something thats just local to Spain?

I'm having the exact same issue on a fresh windows 7 install...pretty annoying. After a few minutes of Genius in iTunes 9.0.2 gathering information about my music library my PC crashes and turns off. This is the only issue my computer has...help?

Clicking on "View more information about this update" for 31.5.0 does nothing

I got a pop-up today that Thunderbird 31.5.0 is available. I clicked on "View more information about this update" because that usually takes me to the release notes and I prefer to read about updates and download and install them myself, rather than have the system do it for me. (I do this so I can save previous versions in case I run into a problem with the latest and want to go back.) But when I clicked on "View more information about this update" nothing happened. It didn't switch over to the browser nor start loading the release notes.

About 5-10 minutes after I had clicked on "View more information about this update" a few times (and had manually gone to https://www.mozilla.org/en-US/thunderbird/31.5.0/releasenotes/ and downloaded and was in the process of installing the new release), my browser opened up three tabs on that page. I guess it was just a very delayed response.

Using JMX to get status information about NetWeaver cluster

Hi everybody,
We are trying to use JMX to get some status information about NetWeaver cluster.
For example, using the MBean with the name u201Ccom.sap.default:name=EL1,j2eeType=SAP_J2EEClusteru201D we can obtain the list of all instances running in cluster. Here an instance is a u201CJava instanceu201D in the NetWeaver terminology.
The method u201CgetInstanceNodeIDsu201D provides us with a list of all nodes of an instance.
Concretely, calling this method for a cluster running on one machine with two java processes, we get the following list of node Ids: u201C0, 1476420, 1476450, 1476451u201D where the last two correspond to the two java processes.
What are the first two node Ids from the list?
How can the last two node Ids be identified as java processes?
How can we obtain status information about each java process (node id) ?
Thanks for all ideas,
Radu

As there seems to be a lot of interest in this subject, and since I found some form of solution, I thought I'd share it with you.
In the es-cli interface, there is a thing called browse mode. Activate it by typing browse after logging in.
Now you can easily browse your network and all of the managed objects. Use getattributes at the end of each branch to see the properties of objects. So far, I've indexed all of the kernel reader module, the health monitor module, the common config reader and the config reader for workgroup servers. If my employer allows, I will post results to http://tille.garrels.be/training/sunmc/ - check later this week.
