Solaris File System/Device Management Information

Hi All,
I a writing a paper about the Solaris operating system and require information about the file system and device management of Solaris 8.
File Management:
I am looking for information or links to sites that would help me find more information about the solaris file system architecture, how it uses drive space, and some of the features of the Solaris file system
Device Management:
I am also looking for information or website links that cover how Solaris talks to devices (overview) and other device management architecture information.
any help is appreciated!

Don't use cp because it converts soft links into hard files. Its even worse when you have cyclic soft links. Use tar or cpio and you should be ok.
i.e. If you have a soft link to a file of 10G, a cp will result in 20G.

How to control permissions in KM using File System Repository Manager

Hello everybody
I have a scenario with 15+ file servers which content needs to be mapped into Portal KM as read-only.
Windows Authentication is configured on the portal, so the users don't need to supply the portal with username/password.
Now the users are of course only allowed to see the same content in the portal as they can see on the file servers. I know that the permission mapping can be done using a File System Repository Manager with W2KSecurityManager, but in that case the users will have to maintain the mapping of rights from windows to portal manually. And with ever-changing passwords this is too big an administrative task. So I am looking for another solution.
My question is therefore:
How can you configure the File System Repository Manager in a way where it the user does not need to maintain "user mapping" manually, but only need to logon to the portal (through windows authentication) and can see the same files from the portal as he/she can see from the file servers.
Can this information in some way be taken from the configured Windows Authentication? Or is the only solution to enable WebDav on the file servers and and follow the "Integration of Windows File Servers into the SAP KM platform Using SSO and the WebDAV Repository Manager"-guide?
Any help will be rewarded.
Best regards,
Martin Søgaard

Hi again Dirk
I just studied the "Integration of Windows File Servers into the SAP KM platform using SSO and the WebDAV repository manager"-guide in depth and I don't quite understand what rights the cmadmin_service and notificator_service are supposed to be given in the Active Directory. In the guide it says:
"A number of global services and repository services need to perform operations on resources in various repositories. For example, the index management service must read all resources it is meant to index. When an index is created, the service user index_service is used. Therefore, this user has to have at least read access to all repositories that are to be indexed. Other users that are used by the SAP KM platform are the service users notificator_service and cmadmin_service. When a search is taking place, it is the user that is currently logged on to the portal."
I dont quite understand what the two service users are doing but more importantly, I need to give the two service users the correct permissions in the Active Directory (or through user mapping). I understand that index_service only needs read_only permissions, but what permissions should the cmadmin_service and notificator_service be given?
Best regards,
Martin

Unable to create File System Repository manager

Hello,
I would like to create File System Repository manager to this path: I have mapped a certain Network drive "
main-uni-fs1\pictures$" to the Portal Machine and under this machine it appears as drive "N:\", inside it there is a picture folder which I would like to create the mapping to. I tried setting the "Root Directory" value to "N:\" and to "
main-uni-fs1\pictures$" but I keep receiving an error message at the Repository Component Monitor (see below).
10X,
Roy

Hello Roy,
1> Create a new path that points to the pictures directory on the system. Enter the path lik
mypc.myorg.com\pictures
Under Sys admin -> Sys Config -> KM -> Content MGT -> Global Services -> Network path
Under the user name and password, enter your username and password
username whould be entered like domainname\username
2>Then create a system in for the mypc.myorg.com server under
Sys admin -> Sys Config -> KM -> Content MGT -> Global Services -> System landscape definitions -> System -> Windows Sytem.
(Assuming u are acessing a windows sytem from a portal running on windows platform).
You need to enter system id and description . Kindly remember the system id, since it would be useful in two places while usermapping and creating the file system repository.
3>create a file system rep mgr under
Sys admin -> Sys Config -> KM -> Content MGT -> Repository Managers > File System Repository
Following properties are most important.
Name , ACL manager cache, Security manager(which you would have to set to W2kSecurity manager)
prefix(this is the folder name that you will identify your repository with) Widws landscape System (this is the sytem id of step 2) and root directory (network path of first step only in this case enter it like this //mypc.myorg.com/pictures)
4>Then under user mapping section, you will find you system (the system id of second step) , enter your name as password.
Initially when you configure your rep manager, you dont need to start ur servlet engine. If you modify any property then you need to re start ur servlet engine.
These are the steps for creating repository
If this still does not get resolved. Then kindly read the limitations of creating the file system repository manager in the link that I had posted in my earlier post.
Thanks and Regards

File System repository manager

Hi All,
I am working on configuring a File System Repository Manager. I followed the documentation at
http://help.sap.com/saphelp_nw70/helpdata/EN/e3/92322ab24e11d5993800508b6b8b11/content.htm
and
https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/284
I made all the configurations and also restarted the portal still do not see the repository in the KM content under root. We are on Netweaver Portal 7.0 on AIX 5.3/DB6, Shared drive is on Win 2003 OS.
Here are the some details on the configurations I made:
Network Path:
jCIFS Protocol: Active
Description: Documents on Shared Drive
Network path:
<IP Address>\public\temporary
password: ***********
USer: Domain\User
File System Repository:
Description: Documents on Shared Drive
Prefix: /abcdef
Root Directory: //<IP Address>/public/temporary/FileShare
Security Manager:AclSecurityManager
ACL Manager Cache: ca_rsrc_acl
Read Only: Not Active
Please advice - thanks -sm

Note: EP and Share Drive are on the same domain.

Hello sm,
You can monotor your repository manager cofiguration, whther it has been activated or not.
It should show in green symbol if it has been correctly configured and active.
Goto system Admin>monitoring>KM>Component monitor>Repository managers-->Check ur repository.... Green color indicate is working fine...
Red color indicate error...
you can check your configuration for the repository.
Example configuration of a UNIX file system repository manager:
Name                = fs_rep_unix
Localroot           = /usr/company/share
Prefix              = /company-share-unix
Read Only           = deactivated
Send Events         = activated
Repository Services = properties, rating
ACL Manager Cache   = ca_rsrc_acl
Security Manager    = AclSecurityManager
You can check your Local root i.e. your Root directory. The format should be correct as given in the example.
Don't foget to appreciate, if helpful!!!

Thanks in Advance for your help..

You must have a lot of small files on the file system.
There are couple of ways, the simplest is to increase the size of the filesystem.
Or if you can create a new filesystem, but increase the inode count so you can utilize the space and still have enough inodes. Check out the man page mkfs_ufs and the option nbpi=n

Protect Solaris file system

Can we protect the file system (folder level protection) in Solaris box using access manager?

patrickez wrote:
If I install Solaris 10 on a x86 platform and add a bunch of drives to it to create a zpool (raidz), how do I protect my root filesystem?Solaris 10 doesn't yet support ZFS for a root filesystem, but it is working in some OpenSolaris distributions.
You could use Sun Volume Manager to create a mirror for your root filesystem.
The files in the ZFS file system are well protected, but what about my operating system files down in the root ufs filesystem? If the root filesystem gets corrupted, do I lose the zfs filesystem too?No. They're separate filesystems.
or can I independantly rebuild the root filesystem and just remount the zfs filesystem? Yes. (Actually, you can import the ZFS pool you created).
Should I install solaris 10 on a mirrored set of drives?If you have one, that would work as well.
Can the root filesystem be zfs too?Not currently in Solaris 10. The initial root support in OpenSolaris will require the root pool be only a single disk or mirrors. No striping, no raidz.

How to get current local file system volume sizes information from OMS?

Hi
I know I can get this information from the table SYSMAN.MGMT$STORAGE_REPORT_LOCALFS.
But info stored in this table is not always up to date, but when going to the page em/console/monitoring/hostFilesystemOverview$target=xxxhostnamexxx$type=host$pageType=current$ctxType=Hosts the information is current.
I have accessed mentioned table in apex, from outside OMS, I would like to have current information instead of old.
How to do that?
Thanks

I think that there is nothing wrong with this table, just that the data is not collected every 5 minutes or so, only on a daily basis.
But as ca107207 said - when you go to the page, showing information about the files system, from the host home page - the data is up to date to the current second.
Therefore I think that OMS ask agent to send this value, but it is then not stored anywhere.
My question would be how to ask agent from outside OMS to get this information?
I have done a little reverse engineering on OMS packages and there should be a way to get this, using some procedures, pl/sql code with generating some cursors etc.
I'm not that good in pl/sql to create something like that, it would take too much time for me. I think that it can't be done without OMS at all, I just have another database with apex on the same host and apex display some information for other users about the file systems etc. It would be nice to have information about file system usage current.
Thanks

Solaris File System/ Virtual File system Documentation

can anybody help me in finding solaris virtual file system documentaion/books ?
thanks in advance,
-mayur

AFAIK, the VFS is not an official (and documented) interface
and may change from solaris release to solaris release
(perhaps even with a new kernel patch).
Other, you can probably get the Solaris 8 Foundation Source,
and use it as the definitive reference documentation ;-)

Solaris file system performance

I run postmark on solaris and ext3 to compare their performance. I found the Solaris is three times slower than ext3. Is there anything wrong? I use "mount" to display all mount point and can see logging is open for the disk I'm testing. I tried closing the logging by "mount -o nologging" and the performance if even worse. So I think the logging is working. But why the performance is still so bad? My computer has 2G ram and the disk I'm using is SATA disk. I found the white paper from SUN says solaris is much faster than ext3 and they use postmark too. Is there any other parameter?

postmark is all about metadata operation performance. Which UFS has always been fairly bad at since solaris is paranoid about flushing metadata and syncing the disks religously to avoid filesystem corruption in case of sudden reboot.
Logging is not primarily a performance optimisation. Its primary function is to avoid having to fsck the disk after an unclean shutdown. So its not surprising that logging doesnt help postmark all that much.
You can try mounting the filesystem noatime which should help a bit.
You can also try ZFS inctead of UFS which supposedly has excellent postmark scores.
You should also be aware that postmark is a very contrived benchmark which only adequately represents the performance of a small subset of programs. Specifically those which manipulate large numbers of small files. Like a mail server.

File system for SAP ECC, EP , BI and CRM installation on Solaris/DB2

Hello,
We are going to implement SAP ECC 6.0 with EP 7, BI and CRM on Solaris operating system with IBM DB2 database.
All these applications are going to be installed on single server, as being a basis person, I know this is not all recommended.
But due to client's requirement and keeping cost factor in mind I need to install all these application on single box.
Now here I need your help. as I basis person, I know the required Solaris file system for SAP ECC 6.0 but not having any Idea about other application like EP/ CRM and BI .
If anyone able to help me with required Solaris file system. it will be great help.
Please let me know if there is any query.
Thanks.

> All these applications are going to be installed on single server, as being a basis person, I know this is not all recommended.

Why not using Solaris zones/container? This decreases the administrative amount tremendeously since you will deal as with "single machines" but they all run together on one box.
> Now here I need your help. as I basis person, I know the required Solaris file system for SAP ECC 6.0 but not having any Idea about other application like EP/ CRM and BI .

Cm repository manager (FSDB) vs File System Repository

Hi folks,
I want to access the documents in a folder using portal and manage it using KM iviews. I was going through a list of repository managers avaialble and got confused with the cm repository manager in FSDB mode and File System repository manager. would like to know which one is suitable for my scenario and why.
Please help me in this regard.
Regards...

Hi Yogi,
the File System Repository Manager has following restriction: You can not use Predefined Properties, versioning, lock documents and create links.
With the CM Repository in FSDB mode you could use metadata like locks and predefined properties, which would be then saved in the DB, but you have to make sure that you don't allow access on FS level (so without portal). Furthermore you can use resource properties like Description, Read-only, and Hidden which is not supported by the file system repository manager.
Hope this helps,
Robert

Difference between ASM Disk Group, ADVM Volume and ACFS File system

Q1. What is the difference between an ASM Disk Group and an ADVM Volume ?
To my mind, an ASM Disk Group is effectively a logical volume for Database files ( including FRA files ).
11gR2 seems to have introduced the concepts of ADVM volumes and ACFS File Systems.
An 11gR2 ASM Disk Group can contain :
ASM Disks
ADVM volumes
ACFS file systems
Q2. ADVM volumes appear to be dynamic volumes.
However is this therefore not effectively layering a logical volume ( the ADVM volume ) beneath an ASM Disk Group ( conceptually a logical volume as well ) ?
Worse still if you have left ASM Disk Group Redundancy to the hardware RAID / SAN level ( as Oracle recommend ), you could effectively have 3 layers of logical disk ? ( ASM on top of ADVM on top of RAID/SAN ) ?
Q3. if it is 2 layers of logical disk ( i.e. ASM on top of ADVM ), what makes this better than 2 layers using a 3rd party volume manager ( eg ASM on top of 3rd party LVM ) - something Oracle encourages against ?
Q4. ACFS File systems, seem to be clustered file systems for non database files including ORACLE_HOMEs, application exe's etc ( but NOT GRID_HOME, OS root, OCR's or Voting disks )
Can you create / modify ACFS file systems using ASM.
The oracle toplogy diagram for ASM in the 11gR2 ASM Admin guide, shows ACFS as part of ASM. I am not sure from this if ACFS is part of ASM or ASM sits on top of ACFS ?
Q5. Connected to Q4. there seems to be a number of different ways, ACFS file systems can be created ? Which of the below are valid methods ?
through ASM ?
through native OS file system creation ?
through OEM ?
through acfsutil ?
my head is exploding
Any help and clarification greatly appreciated
Jim

Q1 - ADVM volume is a type of special file created in the ASM DG. Once created, it creates a block device on the OS itself that can be used just like any other block device. http://docs.oracle.com/cd/E16655_01/server.121/e17612/asmfilesystem.htm#OSTMG30000
Q2 - the asm disk group is a disk group, not really a logical volume. It combines attributes of both when used for database purposes, as the database and certain other applications know how to talk "ASM" protocol. However, you won't find any general purpose applications that can do so. In addition, some customers prefer to deal directly with file systems and volume devices, which ADVM is made to do. In your way of thinking, you could have 3 layers of logical disk, but each of them provides different attributes and characteristics. This is not a bad thing though, as each has a slightly different focus - os file system\device, database specific, and storage centric.
Q3 - ADVM is specifically developed to extend the characteristics of ASM for use by general OS applications. It understands the database performance characteristics and is tuned to work well in that situation. Because it is developed in house, it takes advantage of the ASM design model. Additionally, rather than having to contact multiple vendors for support, your support is limited to calling Oracle, a one-stop shop.
Q4 - You can create and modify ACFS file systems using command line tools and ASMCA. Creating and modifying logical volumes happens through SQL(ASM), asmcmd, and ASMCA. EM can also be used for both items. ACFS sits on top of ADVM, which is a file in an ASM disk group. ACFS is aware of the characteristics of ASM\ADVM volumes, and tunes it's IO to make best use of those characteristics.
Q5 - several ways:
1) Connect to ASM with SQL, use 'alter diskgroup add volume' as Mihael points out. This creates an ADVM volume. Then, format the volume using 'mkfs' (*nix) or acfsformat (windows).
2) Use ASMCA - A gui to create a volume and format a file system. Probably the easiest if your head is exploding.
3) Use 'asmcmd' to create a volume, and 'mkfs' to format the ACFS file system.
Here is information on ASMCA, with examples:

File Systems are not shown in CCMS Monitoring

Hi Gurus,
We have installed all SAP components in Solaris 10 zones including Solution Manager.
Solaris File Systems are not shown in CCMS Monitoring under FileSystem. It looks like SAPOSCOL is not sending the OS data to CCMS. It does not show file systems in OS06 also.
The probles exists on Systems runnig in Solaris 10 zones only and NOT on systems running on individual Servers. [without Solaris zones]
Thanks,
Pj

Hi,
You need take some special considerations while installing SOLMAN on SOLARIS 10 zones. Check these notes

Note 724713 - parameter settings for Solaris 10
Hope this will solve your problem.

File System Repository limitations

Hi everyone
I'm currently involved in a SAP Enterprise Portal project where we among other things are utilizing KM.
One of my customer's requirements are that we integrate an existing fileshare into KM. This fileshare is currently at ~200 GB and is still growing.
Since this is an existing fileshare we are planning on creating a file system repository manager for integrating it into KM.
To verify that this will actually work I have been trying to find any information regarding limitations of file system repositories in KM, but thus far without any luck. It would be greatly appreciated if anyone could point me in the direction of such documentation.
Additionally it would be great if anyone could share their experiences with large file system repositories.
Thanks in advance
Best regards,
