Hi,
When I take a data file offline, which SCN get frozen? Is it the stop scn in the control file or is it the checkpoint scn in the data file header?
Stop SCN is the SCN which gets recoreded in control file when datafile is backup mode or datafile is offline.
Its checkpoint scn in Data File Header. As you the STOP SCN is going to Updated wehn ever there are changes with respective to the datafile.. as it implicitly says that STOP SCN, wit respective Offline datafile will not Update, until next scn generates (until the data file make online)

Offline and Online Procedure

Hi,
I am new in OC, can any body tell me What is difference in Offline and Online Procedure and how we create it .

Hi Daniel,
Now that your O/S is working fine. You will have to install your SAP system in the installation screen choose hom sys copy or db-backup, native method.
Then once installed. Restore either your offline backup or your online backup. If you are using a offline backup to restore you can bring up the sap system directly after the restore.
If you are using an online backup you will also have to apply the sap logs before you can bring up your database.
For the restoration procedure you can use both SQL Query or you can do it via the SQL Server enterprise manager.
For hom sys copy guides - check the url http://service.sap.com/systemcopy
This will work. Please award points if useful.
Thanks, Dibya

Skype Going Offline and Online Randomly?

Hi, my Skype keeps going offline and offline very quickly, not even offline then a few seconds later, online, as in every second it's on and off and on and off... etc. Also, if I try to message someone while it's doing this it gives me a really far-off date like February 5, 2020, but it's only when this is happening. In addition, it sometimes drops me from calls and it randomly tells me it's like, five of my contact's birthdays at once. I'm running Windows XP and I'm sure I have the latest version, as I just uninstalled then reinstalled Skype. I'd like to know if this is my internet or Skype freaking out, thanks for reading
Solved!

Target Data File Name and Path

Hi,
I'm trying to deploy a mapping that writes data into a file, but I need to dynamically set the name and the directory where I want to write this file. The only workaround I found was manually change the pl/sql generated code and change the values in the FOPEN call with a parameter, but this is no what I really want to do. Does anyone know how to tell WB not to hardcode the file name and path?
I really appreciate you time,
thanks in advance,
Matias

Carla,
Unfortunately our releases do not go that fast...
What you could do as an intermediate solution (this is what I would do) is create your mapping and load into a staging table (this can happen in set-based mode so would be fast). In a post mapping process you manually write to the flat file by making the calls to FOPEN etc. by selecting from the staging table. The post mapping process can have an input parameter that you dynamically pass (i.e. via a mapping parameter) and set the file name.
Mark.

Offline and online back up

what is the offline back up and online back up,

hi s reddy,
in general words,complete backup is called offline backup which needs to schedule downtime and complete backup is taken.
online backup is nothing but daily backup when the system is up and running and no system downtime is required.

Data files archival and poling interval in XI

Dear Experts,
I appreciate if you could help me to know the best options for the below
1. How many days is ideal to keep the archived data files in XI
2. What is the best option for file polling interval in file adapter.
Thanks and Regards.
Yerragadda.

Hi,
1. How many days is ideal to keep the archived data files in XI
--> It depends upon the volume of data fiels archived as well as the importance of those archived data.
Instead of archiveing it on XI server, its better to maintain the archived files on some host (FTP). On sender side file adapter you can give the another path/location to maintain the archived files.
2. What is the best option for file polling interval in file adapter.
---> Polling Interval will be set when you need to pick the file and sent into XI. i,e when your scenrio is like File-XI-Idoc/RFC etc.
You may give the polling interval based on frequency of files, Either you can control the commmunication channels externally also.
While configuring a sender file adapter, a major mistake that we often do is keeping file adapter communication channel polling interval less and in test mode. It is not an error, keeping it in test mode with less polling interval but, often we forget about it, keeping the adapter channel active and it loads the server memory unnecessarily.
The link below will help you understand things better.

Frequent random software crashes taking out files, applications and OS

We are a small niche publishing company with a network of 9 Macs of various ages - some very new running 10.6.3 and others older (mini macs running 10.5). We run MS Office (2004,2008 and 2011), Extensis Suitcase (Fusion) and QuarkXpress v8.
About 6 months ago one of the Mac users (running OS 10.5) complained that his Microsoft User Data folder had moved. I moved it back but everything then went downhill from then on. One by one all the Macs became corrupted in some way, and they nearly always followed the same pattern. Firstly files or folders on the desktop go missing (not in trash) then Extensis Suitcase and QuarkXpress become corrupted. Quite often Word or Entourage fails too. On many occasions the OS has also become corrupted so I have to reinstall everything.
This now happens on a daily basis, although 2 or 3 of the Macs seem to have settled down and have not played up for some weeks. As you can imagine we have wasted a tremendous amount of time and energy on this. We employed the services of an IT specialist who cannot work out what the problem is. He thought it was a file-sharing problem and installed a Mac Server but it has made no difference.
Someone in an online IT forum suggested that if we have a Quark document that keeps getting over-written (which is the case with us) then it has probably become corrupted and it corrupts whatever is stored near it on the hard drive, so could quite easily take down applications and the OS. This seemed logical and I asked the department to build new pages from scratch and banned them from opening the old pages. This has made no difference.
QuarkXpress themselves said that Quark can crash if you edit and save a document which was created in an earlier version of Quark. Well, Quark crashes all the time and seems to be the worst piece of software ever written in my opinion, but it shouldn't wipe out your whole computer, should it??
I had also suspected a virus and put Kaspersky on a couple of the most-used Macs for a while but it didn't find anything so I didn't bother reinstalling it again when I next had to do a re-install of the Macs.
I am now suspecting it could be something to do with MS Office 2004. I have some older Mac Minis which should be running it fine (but don't) but it has also been loaded on a few of the more modern iMacs running 10.6. I notice the two Macs running 10.6 which have "settled down" and haven't played up for weeks run Office 2008 and 2011.
I am also posting this problem to Microsoft and Quark in the hope that someone somewhere has experienced this before and can come up with a solution.

The theories that best fit your description are (1) sabotage and (2) defective third-party software.
As for (1), check your logs carefully for evidence of unauthorized access, either remote or local.
As for (2), look for anything you installed on all the affected hosts that runs as root or includes a kernel extension. Commercial "anti-virus" software would be a prime suspect.
Verify the directory of the startup volume of each client in Disk Utility (you can do this via a remote shell with diskutil.)
+QuarkXpress themselves said that Quark can crash if you edit and save a document which was created in an earlier version of Quark. Well, Quark crashes all the time and seems to be the worst piece of software ever written in my opinion, but it shouldn't wipe out your whole computer, should it?+
No, it shouldn't and it can't.

Clicks in Bnce! (both Offline and Online)

... i seem to be haunted by clicks and pops since installing LP8...
Anybody else have clicks when bouncing down ??
Thanks!

Sorry, let me correct myself. The clicks and pops are in the project itself already. Two clicks/pops occuring always in the same places.
However, talking bout clicks and pops.... I now get clicks and pops again. In two places of my project, they are always clicking/popping in the two exact same places.
I have checked:
any fades forgotten? NOPE, all there
any waves plugins distorting?? NOPE, all green..
any automation chaos? Nope, all smooth.
Other than that, i have:
restarted computer and audio interface
restarted software
bounced offline as well as online
changed buffer size (YES! tried all settings)
checked that my project / audio files are all in one place - TICK
Kinda don't know what to do anymore, really... Could it be an overload? I'm using quite a bit of Space Designers (7 of those plus a lot of other plugins). But then if it was an overload, would the clicks always appear in the same place?
Many thanks for any inputs guys!

How to confiuge RMAN offline and online back-up at a pre-determined time.

Hallo!I am an Oracle newbie currently studying the Oracle 10g Database Administration Certification.Still very new to Enterprise Manager.
My query is that can you configure an offline database back-up such that you can set up an offline backup at a pre-determined time?
I am assumng a real-office scenario where a DBA would like to have an offline back-up at night e.g. at 1 am when they are no users in the office.If the DBA can set the system such that everday at 1 am ,the instance shuts down,back-up is done e.g a backup set that can be stored on tape,then after backup the instance re-starts itself.All this should be automated such that by the time staff report in the morning ,the instance is up and running and users can work seamlessely
How can I automate this entire process using RMAN and/or Enterprise Manager or a sript to achieve this?Also,I would like to know if you can automate the same for online back-up such that it can backup while instance is still running and users are accessing the DB.
Please help me on this and I shall be infinitely grateful.Thanks in advance.

Hi,
On UNIX server, you can use shell script and sql scripts that can do this job for you. Once the scripts are tested succesfully, you can put them in the crontab.
Crontab entry should reflect the time, day, week, month details as you thought to schedule it.
This link may help you. http://www.dbasupport.com/oracle/scripts/Backup_Recovery/RMAN_Backup/

Data files are offline / tablespace offline

I am confused on the concept of data file offline.
What happened when you take data file offline?
Is data file offline because of disk damage? we see the error that data file is haning a problem, we have manually to take data file offline? how?
Why is tablespace offline but data file is still online?
Please help!
Thanks

What happened when you take data file offline?The offline datafile means simply that the file is not available anymore for the access. All the objects for the offline file become inaccessible for the users to access.
Is data file offline because of disk damage? we see the error that data file is haning a problem, we have manually to take data file offline? how?Yes it can happen that the data file goes offline because of any kind of damage either over the disk, or also with the file itself. For example, there may be a chance that the file is not available anymore , may be because someone has deletedthe file. So most of the times, Oracle would offline the file by itself. In any case, if the file doesn't go offline by itself than you need to take it offline yourself as the recovery for the file can't happen if its online. You would get the error messages that oracle can't acquire the exclusive access over the file.
Why is tablespace offline but data file is still online?Not sure that I did see this ever myself. Tablespace is nothing but the container for the datafile so if there is a file of it which is offline and that's the only file in the tablespace, the tablespace can't stay as online. Show us an output for the same.
The links given by Anantha are must for you to read the cocept of offlining a tablespace. Make sure you read them for sure.
