Query on file system and sapcpe

If, I have a distributed installation with central services instance on Windows and other App servers on AIX, then my sapmnt is on windows ...
In this scenario, my /sapmnt/SID/exe will contain the Windows kernel and /usr/sap/SID/D01/exe/ will contain the AIX kernel
However, the sap help pages say sapcpe will replicate the kernel from /sapmnt/SID/exe to /usr/sap/SID/D01/exe .... Is this true for distributed installation too ? Will this lead to conflict ? How can I disable this copying ?
Secondly, during a kernel upgrade do I need to update "same AIX kernel into" /usr/sap/DASID/SYS/exe and /usr/sap/DASID/SMDANO/exe as well ?
(where DASID is diagnostic agent SID)
Thanks,

ok.. but the global host (windows) contain Windows kernel files.. and in that case, they will be copied to AIX kernel dependent directory ?

OES11 SP2 - Linux File System and NSS Pools & Volumes

Planning to install our first OES11 SP2 server into an existing tree - the
idea is to run this new OES11 server virtualized on VMware ESXi 5.5
The existing tree has two physical NW6.5SP8 servers running eDirectory
Version 8.7.3.10b (NDS Version 10554.64). One of the existing Netware
servers is used for DHCP/DNS, File Sharing from three NSS volumes and
Groupwise 7.0.4 whilst the second server is used for FTP services and
eDirectory redundancy. Ultimately the plan is to have two virtualized OES11
SP2 server with one for file sharing and the other for making the move from
GW7 to GW2012. And we're planning to stick with NSS for file sharing on the
new OES11 SP2 server.
I've come across a couple of posts for earlier versions of OES which
recommended not to put the Linux Native OS File System and NSS storage
pools/volumes on the same hard drive. Apparently the advice was a result of
needing to allow EVMS to manage the drive which could be problemmatic.
I've read the OES11 documentation which says that "The Enterprise Volume
Management System (EVMS) has been deprecated in SLES 11, and is also
deprecated in OES 11. Novell Linux Volume Manager (NLVM) replaces EVMS for
managing NetWare partitions under Novell Storage Services (NSS) pools."
So I'm wondering if there is still a compelling requirement to keep the
Linux Native File System and NSS pools/volumes on separate hard drives or
can they both now safely co-exist on the same drive without causing
headaches or gotchas for the future?
Neil

Hi Willem,
Many thanks for the further reply.
So we can just use the VMWare setup to "split" the one physical drive into
two virtual drives (one for the OS and the second for the pools).
And I've seen posts in other forums about the need for a decent battery
backed cache module for the P410i controller so I'll make sure we get one
(probably 512Mb module + battery).
Can I ask what is the advantage of configuring each VM's virtual disk to run
on it's own virtual SCSI adapter (by setting disk1 to scsi 0:0, disk2 to
scsi 1:0, and so on)?
Cheers,
Neil

Image: display from local drive, upload to server file system, and display from server

Hello,
I am using jdev 11.1.2.4.0...
The requirement is that users would like to upload images from their local drive to server drive and they would like display images from server drive later.
We don't want to keep images in database. I am not sure what the solution should be; however, I plan to ....
1. create a table to keep an information of images -- image_id, image_location (server drive), image_filename
2. create a page where users can enter image information and specific filename from a local drive (I think I will use inputFile component) and provide the preview button to display an image on screen before save it. To save data is to save information to the database and copy an image file to the server drive (the destination location for image files is predefined.)
3. create another page where users can browse information from the database and display an image for a selected record by getting from the server.
I need suggestions on...
1. how to display an image on page from the local drive?
2. how to copy a file from a local drive to a server?
3. how to display an image on page from the server drive?
Thank you.

Where Timo saves images to the database, you save it to the file system (examples on how to do this from Java are available plenty if you just Google for it). Similar to Timo you then use the image tag to display images. The difference is that you can directly add the URL from the database table.
The benefit of using a database to host images is that you are not dependent on file server structures though

BIP and Siebel server - file system and load balancing question

1. I just need to understand whenever the reports are generated through BIP, are there reports stored on some local directory (say Reports) on the BIP server or Siebel File system? If on a File system how will archiving policy be implemented.
2. When we talk of load balancing BIP Server. Can the common load balancer be used for BIP and Siebel servers?

File system and LR2 file system view summary

Hello,
Is there a way when navigating a directory via the Folders panel to click on the folder and get summary information about the contents of the folder both from a file system perspective as well as a Lightroom perspective?
file system perspective: number of physical files supported by LR2 in the folder
LR2 perspective: the number of files that have virtual copies, how many total virtual copies total, how many photos are in stacks, how many stacks, etc.
Thanks,
Matt

 No, you can't specify an entire filesystem as something to cluster. I
 suggest using NFS or some shared filesystem and then running a cluster
 off of that.

Backup to file system and sbt_tape at the same time?

hello!
is it possible to do a rman backup to disk and sbt_tape at the same time (just one backup, not two)? the reason is, that i want to copy the rman backup files from the local file system via robocopy to another server (in a different building), so that i can use them for fast restores in the case of a crash.
if not, what is the recommended strategy in this case? backups should be available on tape AND the file system of a different machine.
environment: oracle 10g, windows server 2008, commvault for backup on tape
thanks for your advice.
best regards,
christian

If you manually copy backupsets out of the FRA to another location, but still accessible as "local disks", you can use the CATALOG command in RMAN to "catalog" the copies.
Thus, if you opy or move files from the FRA to /mybackups/MYDB, you would use
"CATALOG START WITH /mybackups/MYDB" or individually "CATALOG BACKUPPIECE /mybackups/MYDB/backuppiece_1" etc
Once you have moved or removed the backupsets out of the FRA, you must use
"CROSSCHECK BACKUP"
and
"DELETE EXPIRED BACKUP"
to update the RMAN repository. Else, Oracle will continue to "account" for disks pace consumed by the BackupPieces in V$FLASH_RECOVERY_AREA_USAGE and will soon "run out of space".
You would do the same for ArchiveLogs (CROSSCHECK ARCHIVELOG ALL; DELETE EXPIRED ARCHIVELOG ALL) if your ArchiveLogs go to the FRA as USE_DB_RECOVERY_FILE_DEST

Cluster file system and BDB - does it work ?

Hi,
I've read in the reference guide that:
" No commercial remote filesystem of which we're aware supports
coherent, distributed shared memory for remote-mounted files"
What about cluster file systems like veritas cluster file system ?
Can I use this file system with BDB ?
I'm trying to find a solution for having one database visible from two computers.
Reader and writer exist on each machine. Any clue how to do that ?

File systems and fragmentation

I'm a converted ubuntu user, and I love arch to death now... but here's my question.
When I was using ubuntu I read a post on lifehacker.com that said
Defrag – Nope. Linux file systems do not have a need to be defragmented.
Original link: http://lifehacker.com/5817282/what-kind … y-linux-pc
Since I've always used ext4 and I still can't find anything on needing to defrag an ext3 or ext4 filesystem I assume it still holds true. However, I was reacently read this article on the wiki: https://wiki.archlinux.org/index.php/Ma … filesystem
and decided to try out XFS on my /home partition. So i checked out the XFS page. all it has is a small section of fragmentation and how to defrag it and check how fragmented it is.
I also remember seeing somewhere on the wiki (although I can't remember where) that JFS also needed it as well (might not have been JFS not entirely sure).
So is this something I should worry about as I used to on windows? Are ext3 and ext4 really immune as they seem to be? And what are your recommendations on file systems to use?

Zarcjap wrote:And what are your recommendations on file systems to use?
If you're asking which FS you should use, there are already a few threads about this e.g. https://bbs.archlinux.org/viewtopic.php?id=135330
It depends on what are you going to use it for.

Query on File System Repository..Please guide

Hello All,
I have successfully created the File System Repository, connecting a folder on my windows 2000 machine to an EP (Netweaver 2004s) KM, following the steps like:
1. Creation of Windows System
2. Network Path since the server and my machine are seperate systems
3. Creation of the File System Repository.
You may refer to the above steps in detail using <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/e3/92322ab24e11d5993800508b6b8b11/frameset.htm">link</a>
Question:
1. After the successful creation, I deleted the Windows system created, but the File System Repository was still working all fine. Why so? Shouldn't this throw me an exception?
2. While creation of the Windows System, I entered the ID and Desription.
In the Network Paths, I entered the folder's name (folder which is on my machine/which is to mapped) & my machine's username + password.
Then how does the system/server know which windows system is to be mapped for the netwrok path?
In other words, what is the mapping betweeen the Network path & Windows system?
3. If you access the above link, there is a step of creating a System in the Portal System Landscape. What is the need to do this? Can you please explain......
Why create a PCD System object, System Alias, etc....
Would appreciate if you please help me understand this concept.....
Awaiting REply.

During Windows install, says the Bootcamp Windows partition is incorrect file system and won't install

I had another Macbook Pro retina which I installed Windows 8 on with no problems via bootcamp. I just updated to the late 2013 model of the Macbook Pro, and attempted to do the same thing but have had problems. I create the partition for Windows with Bootcamp, restart the computer, and after I enter my security key in the Windows installation screen it comes to the screen where you have to select the appropriate installation drive. When I select the drive I created for Windows, it says that it can't install due to the file system. I have no idea why I'm having this problem because I had done this once before....I can't for the life of me figure out what's wrong and I'm at a loss.
If anyone can point me in the right direction I will greatly appreciate it...also let me know if there are differences from the early 2013 model and late 2013 model that would've created this problem. Thanks!!
Robert

Well, here is what happened...
Somehow in making a Windows partition then removing the partition so many times I created an error where it only showed 1/2 of my hard drive...like it was starting to create the second half for the windows side and ran into an error.
So this turned out to be a blessing in disguise, because what I had to do was go to "Command + R" when I was starting up and format the entire drive, all 500 gb. This formatted the whole drive and must've erased whatever was causing the trouble.
Of course, then I had to reinstall OS X, and reinstall my Time Machine backup, but then I opened bootcamp and created the Windows partition again. This time, when I ran the EFI installer you were referring to on the far right (which I had tried before), it allowed me to click next and continue once I selected the Windows partition. Thank God! It must've fixed whatever file system error was hanging it up there every time....because it's installing now.
What I would suggest if all else fails, just format the whole dang thing. Then try from square one and see if you can install

Note on applying patches to the file system and database

Dear all,
I am new to Oracle E-business suite. Anyone in the house that can give a note (either a step by step or oracle metalink note) on how to apply patches to a file system or database.
Kind Regards.

Hi,
Steps to apply an application patch:
- Stop all application services (keep the database and the database listener up and running)
- Download the patch from Metalink
- Copy the patch file to any directory (i.e. /u04/patches)
- As 'applmgr' do the following:
- Source the environment file
- $ cd /u04/patches
- Type 'unzip <patch_number>.zip'
- cd <patch_number>
- Type 'adpatch'
- When it prompts you to enter the patch driver, type 'u<patch_number>.drv'
Apply the patch on the database tier first then on the application tier.
Do not forget to 'Enable Maintenance Mode' from adadmin before applying the patch. Once you apply the patch successfully, 'Disable Maintenance Mode' from adadmin.
And, always follow the steps in the patch README file.
For database patches, follow the steps in the patch README file and apply the patch using opatch as oracle user.
For more details about applying patches, please refer to:
"Oracle Applications Maintenance Utilities" manual

Shared file system and other questions

Hi,
 Is shared file system common for all WL in the cluster or each WL has its
 own one.
 Next questin is connected with proxy server.
 I'm not sure if there should be one proxy server for two servers working in
 one cluster or each server should has own proxy server (I mean WL proxy
 server).???
 In my opinion there should be one proxy server which redirect requests to
 server in cluster using some balancing method. But when I read documentation
 about cluster's architectures I saw the picture where each WL cluster server
 had proxy own server. I'm not sure if this picture showed only outline of
 architecture or it was real solution???
 Is it better to install another proxy server (for example Apache) than WL
 proxy server?
 In previous questions I asked if it is possible to replic static classes,
 fields etc. Prasad Peddada told that it is not replicated. But I wonder if
 there exists some method to force replicating it.? Maybe we can implement
 some method and run it?
 Thanks,
 Best regards,
 Robert


Mike.
 In WLS51 cluster, it is better to specify different workingDir for each
 server. You can create a weblogic.properties in your per-server directory
 and add jspc properties in that file.
