Small doubts regarding devices and permissions

Hill all,
Continuing with my experiences with Oracle 11gR2 and Solaris 11, i came up with some "small" doubts regarding the permissions and owners of the devices to be used as ASM diskgroups. I was able to install Grid and the database, both 11.2.0.3.0, in a single-instance configuration, but i had a small issue when creatind the diskgroup for the database data (+DATA). I created 3 devices (VirtualBox) to be used in the +DATA dg, and gave the the "oracle:dba" owner, with the permission 660. My doubts are:
1) It wouldn't be more correct to make the owner of the device the user grid? (grid:dba)
2) The permission 660 to the devices is the correct, or recommended permission? It did work with this permission.
Thanks in advance.

It depends on the user and group that runs the ASM instance. It can be oracle/dba, but can also be a different user, e.g. grid/asmadmin
http://docs.oracle.com/cd/E11882_01/install.112/e22489/storage.htm#CHDFAGJD
660 means rw. That should be ok. No other user/group than the ASM instance needs to access the devices.

General doubt about devices and java applets

I have one general doubt abt devices.
Do all devices come with an SDK so that any language can interact with them?.
Whats does it mean if i say that i need to build a CAB file for the devices
and use them in my html object tag.
Can programming languages like java(applets) or asp interact with devices
once if we specify the classid and the cab file location(codebase)

Let me make it more clear
What i need is if we r using an ActiveX Component then we pack the .ocx and inf file into a cab file and give the location of the CAb file in the codebase attribute of object tag.
When the browser renders the page, it will look into the classid attribute of object tag to see whether there is an entry in registry if not it will go to the location specified in the codebase and get it registered locally.
As you know ActiveX works on windows.
I want to implement the same thing in a platform independent way.
So i chose java applets.
Now i don't know what to do in this codebase part.
i need to install the device driver files and all from the server once a person view the web page.
when we use activex the classid field represents the device's entry but when we use applets thats the version of java being installed.
Can any one suggest an idea to move.

Small Doubt Regarding SY-MANDT

Hi All,
     SELECT changenr FROM cdhdr CLIENT SPECIFIED INTO CORRESPONDING FIELDS OF TABLE it_cdhdr
                                         WHERE mandant = syst-mandt
                                         AND   objectclas = 'MATERIAL'
                                         AND   objectid   = wa_matl-matnr
                                         AND   tcode      = 'MM02'.
     I have written the select stament as shown above.
     In this i have a doubt like adding a field sy-mandt in the where condition will increase the Efficiency of program or not.
regards,
raghu.

Hi..
No doubt the efficency would be affected but from business point of view there will many things that need to be checked as in:
If you are viewing data from CDHDR and CDPOS which is client specific then you are not viewing complete data.
These tables give us and document changes made to a particular object in SAP but if anything is cross client like company code(lets assume) then changes to it wont be visible in all the clients..
so there can be some key information you can miss out while working on some of the objects.
else in this case its good to make query cross client.

Doubt regarding query and subquery

Hi guys,
if I run the following query :
SELECT NUM_OCORRENCIA, NUM_ENVOLVIDO FROM BO_VEIC_ACIDENTE BVA
WHERE BVA.NUM_OCORRENCIA = BE.NUM_OCORRENCIA
I get the following error message : ORA-00904: "BE"."NUM_OCORRENCIA": invalid identifier
because we dropped the column num_ocorrencia.
But if I run the same query as a subquery , like :
SELECT COUNT(BE.NUM_ENVOLVIDO)
FROM BO_ENVOLVIDO BE ,
BO_TIPO_ENVOLVIMENTO BTE
WHERE BE.ID_ENVOLVIMENTO = BTE.ID_TIPO_ENVOLVIMENTO
AND BTE.CODIGO IN ('0100','0200','0300','1302','1303','1304')
AND (BE.NUM_OCORRENCIA,BE.NUM_ENVOLVIDO) NOT IN (SELECT NUM_OCORRENCIA, NUM_ENVOLVIDO
FROM BO_VEICULO_ENVOLVIDO BVE
WHERE BVE.NUM_OCORRENCIA = BE.NUM_OCORRENCIA)
AND (BE.NUM_OCORRENCIA,BE.NUM_ENVOLVIDO) NOT IN (SELECT NUM_OCORRENCIA, NUM_ENVOLVIDO

WHERE BVA.NUM_OCORRENCIA = BE.NUM_OCORRENCIA)
AND BE.NUM_OCORRENCIA IN (SELECT NUM_OCORRENCIA FROM BO_OCORRENCIA_POLICIAL WHERE COD_TIPO_OCORRENCIA = 1)
AND BE.NUM_OCORRENCIA = '2006-000000406' ;
no error message are displayed. So I want to understand why Oracle get this behavior in this query.in the last query i got the result ' 0 ' . why Oracle didn´t showed me the same error in the second option ?
thanks,
Felipe

I think you need to get some coffee ;)
It's a scope issue the table alias BE does not exist in the first query but does in the second so it can be referenced in the subqubquery.

I was looking at the "Find my iPhone" app and I have a doubt regarding how it works for the macbook. In order to detect the location, the macbook should remain signed into iCloud. What if the thief logs out of iCloud. Would we able to locate the macbook?

I was looking at the "Find my iPhone" app and I have a doubt regarding how it works for the macbook. In order to detect the location, the macbook should remain signed into iCloud. What if the person who has stolen my macbook logs out of iCloud.
It should work fine for iPhone/iPad because we can enable "Restrictions" to prevent the user from signing out of iCloud. Do we have simialr settings for the macbook?
Thanks,

If it's not on the device list, it indicates that someone has gone to Find My iPhone on icloud.com and manually deleted it from the device list (as explained here: http://help.apple.com/icloud/#mmfc0eeddd), and it has not gone back online since (which would cause it to reappear on the device list; Find My iPhone has been turned of in settings on the device; the iClolud account has been deleted from the device; or the entire devices has been erased and restored.
Unfortunately, there's no other way to track the phone other than through Find My iPhone. You could call your carrier and see if they would blackliste it so at least the theif couldn't use it.

The backup files for my devices are saved to my internal hard drive. I have a small internal hard drive and would like them to be saved to an external drive. How can I change where iTunes automatically backs up to?

The backup files for my devices are saved to my internal hard drive. I have a small internal hard drive and would like them to be saved to an external drive. How can I change where iTunes automatically backs up to?

This has nothing to do with iTunes as iTunes provides no way to move or relocate the backup files.
A search of google or the fourms would reveal ways to create a folder link to relocate the physical location where the files are stored.

Some email images do not show while using the icloud web app. I can see the images on my IOS devices and in gmail but I only see a small gray box in the icloud web mail app. Load HTML images is checked in preferences.

I've seen the opposite issue. My wife recieved an email with jpg attachments. She couldn't see or print them on her iPhone 4S but they showed up fine in iCloud or in the mail app. I had her forward the email to herself and then they showed up. I assume there is an issue with how Apple is processing the attachments and resending causes them to get reformatted in a way that makes them easier to handle.
So yeah. Seems like some bugs. Hope Apple fixes them soon.

Users and permissions for a small home server

Hello community,
I have been using Linux on the desktop for many years now, but unfortunately my knowledge about servers is very limited, almost non-existent. Therefore my question is most probably equally well fitting here and into the newbie corner.
I'm trying to set up a little home server which should be in charge of following tasks:
- CUPS print server in the local network
- access to shared files through NFS in the local network
- backup (again over NFS)
- an Owncloud server
- maybe a mail server in the long run (NSA, paranoia, etc. )
For now I have set up the print server, the NFS server and was working on the Owncloud installation, when Owncloud gave me some errors with users and permissions. So I was led to the idea of rethinking the users and permissions on server. So far there is only the root user who may do everything. This seems like a quite unsafe configuration. I'd like to make it safer. First, the printer, the backup and the locally shared files should be accessible from the local network only. SSH access should also be accessible locally only. The Owncloud file folder should be accessible from the internet, but of course only for the Owncloud users registered to the Owncloud server.
What is the best way to set up users and permissions for such a set up?
Thanks for any hints,
PhotonX

Hi, i think it depends who are you serving for, if you are just serving for a small office or home server or a big organization. The following quick thinking just came to me:
I think cups set automatically a system user of its own, and runs as it, so no trouble there. Cups also has the option to set users and it uses the system users as default, i think it depends in in how many printers/users your have in your server.Users that can manage cups are in the lp group.
For nfs every user should have their home, samba is also a good option if you have windows computer in your network and it integrates better with graphical file managers like nautilus in the clients side, but it is a hassle to configure.
You should run the web server (owncloud ) as it own user, maybe you can manage to set something up for owncloud in the filesystem, but owncloud uses a database, and the users for owncloud are stored in there, and they are not system users.
You can configure ssh for local use only enabling the corresponding subnets in your /etc/sshd.conf and optionally but recommended you can set a firewall and permissions. You can use iptables but i prefer ufw for simple setup.
I think you should read the wiki:
https://wiki.archlinux.org/index.php/users_and_groups
and the other respective topics in the wiki.
Also as an advice i know that arch linux is a great distribution, but you have to do more work to mantain a stable server. I would recommend debian or another more conservative distro, but of course it is your choice.

TS1702 adjusting the security and permissions settings for your device.

I Updated to the ios6, then tried to save a video to the camera roll. The app asked if I would allow it to have access to my photos, and I said "no" and now I can't save any videos made with that app to my camera roll. I contacted the support at vidrythum and they said I had to contact apple and ask how to adjust the security and permissions settings for your device. Any ideas??
thanks

WOOHOO!!
You are a diamond!!
All working now. Thanks mate.

Different Text Size for different mobile devices and Tabbed View Application

Hi,
I am developing an sample mobile application to target all mobile devices (IPhone/IPad/IPod and Android).
I am facing an Issue that i am using default text size for the TextInput, TextArea and label but text size look so small for some devices, i discuss this with some(unkown) person(he is an IPhone developer).
He told me that in Iphone development for different devices they use different text size.
So how would I do the same at our Flex Mobile application ?
Please provide me help regarding this
There is one more problem in the application. I have tabbed view application, and i assign the firstview of the tab after 10 or more seconds of interval so that data will load in the application properly.
But issue is that my first tab is not show anything at first go. When we switch the tab then it loads the screen and application work fine.
Please provide me any help so that i can see the first Tab Screen.
Thanks

Hi there. For your font issue you need to set up a variable call it var fontSize or something. Then have an if statement that reads something like if (stage.stageWidth <= 320) fontSize=8 else if (stage.stageWidth > 320 || stage.stageWidth <= 640) fontSize = 12.
Then instead of giving your font a size give it the size of fontSize variable and it will check for stage width or whatever you base it on and apply that size to your text field.
I had done this for an app I did for Kellogg Garden Products but if you notice when you go from portrait to landscape mode the font size increases using this technique.

LadySarah
You cannot upgrade from v6 to v7 without purchasing iLife 08.
Can you give more details about your crashing issue. Make of camera etc.,
You can start with the troubleshooting basics:
1. Repair Permissions using Disk Utility
2. Delete the com.apple.iPhoto.plist file from the home / library / preferences folder. You'll need to reset your User options afterwards.
3. Create a new account (systempreferences -> accounts), create an iPhoto library there and see if the problem is repeated. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.

Small confusion about aggregates and attribute change run.. plz explain

hi bw experts,
i am having a small confusion regarding the aggregates and attribute change run.
as far as in know if there is any new master data loaded, then we will activate it by context menu on the particular info object and select the option activate master data.
the second one is going to tools--?apply hierarchy/attribute change run option.
my doubt is is the attribute change run related to aggregates is yes then how,.?
appreciated if you plz help me in detail both these concepts and wherther there is any connection between them.
thanks & regards.
vijay..

Hi Vijay sagar,
ATTRIBUTE CHANGE RUN:
1)It's used after you change (add/delete/modify) attribute in the master data. You've to make it in order to have an effect after you modify it.
2)Once the master data has been loaded, the hierarchy/attribute change run is performed. Once this process chain has been ended correctly, master data and texts are available in an active format in SAP BW.
To get it :
1. tcode : RSA1.
2. Tools -> Apply Hierarchy/Attribute Change
3. tap on Info-object list button (checking what master data you've modified before).
4. tap on selection button for type of job
5. Execute.

AGGREGATES:
1)Aggregates make it possible to access InfoCube data quickly in reporting. In doing so, aggregates help improve performance. (See Aggregate.)
2)In order to be able to insert aggregates effectively, it is important to find out which aggregates are frequently used or have not been used in a long time.
3)Aggregates contains not only general data but also data that appears in an aggregate after data is filled and rolled up. Reporting in this InfoCube reveals how often data was loaded into an aggregate, how long filling and rolling up took, and whether it took longer to read or write the data.
4)Adding when Rolling Up in Aggregate counts the time required to write the data to the aggregate.
The Records, Read for Aggregate Structure key figure counts the data records that are read for constructing the aggregate.

Urgent--- small doubt

Hi
I need some docs for 8i installation on win2K. Also I've a small doubt.... I want to move one database (8.1.7.4) to a new server. On this new server I have to install Oracle 8.1.0...... Now the doubt is if I do backup/restore from the old server, do I still have to apply patch 4 on the new server???
Any input is appreciated.
Regards

Hi,
I suggest you apply the patch becuase the database backup has the version info which is 8.1.4. Thus when you will use the 8.1.0 Oracle kernel to start a 8.1.4 database then it might give an error. It is best suited to apply the patches in the new server the way it is in the old one. Once you have applied the patches in Oracle kernel (Oracle Software) you may go ahead with opening the database.
This will keep the versions of the Oracle kernel and the version info in the database control file in sync.
Regards.

Sharing one iTunes account between 3 devices and a Time Machine

I have a iphone 4S
i have an Imac
I have a Time machine
I have a macbook
I have Apple TV - hard wired to the TV
All devices are using the latest versions of OSX and IOS
My Iphone syncs with the imac Itunes account
All my Music is on the Time Machine which is connected to my router (virgin Broadband)
The itunes account on the Imac is aware my music folder is on the time machine.
My question is - how do i get to use my Itunes account on the Macbook and update playlists and Playcounts on the Iphone and Imac?
I want to be able to play my music on the time machine from any of my apple devices and it update one music Library.
Is there a way i can do this?
Regards and thanks for your time

You can sync your music to each of your devices using the iMac which is referencing the library on your itunes. So all good there. If you want to share the information amongst all your devices then home Sharing will do it. But only if you are in your own network.
If you want to use the same klibrary on your Macbook as your iMac you can point it at the Library on the time capsule.
If you want the content on your Macbook then Home Sharing between computers will let you copy it but it will not copy over playlists etc
Using home sharing you have to have itunes open on your iMac so that the other devices can see it. Also ensure that sleep is not set for your computer.
