RedHat GFS + Oracle, is it officially supported?

Hello all,
RedHat has just released a Global Filesystem (GFS), which is a POSIX compliant filesystem that can be accessed from multiple nodes at the same time. This differs from OCFS in that it can be used for any type of file, not just database files as supported by OCFS. They also released a white paper discussing Oracle 9i RAC and GFS, but I find nothing out on Oracle's site which says it's officially supported by Oracle. Does anyone have any information concerning this?
By the way, the GFS release information can be found at http://www.redhat.com/software/rha/gfs/
Thanks,
-Adam vonNieda

on the contrary, this was announced a while back but for some reason the announcement was pulled out (i had it implemented for a client and didn't know the announcement was pulled out till now)
it seems there's support for compression though, check:

SAP BW supporting Oracle 10g

Hello!
Does anybody know if SAP BW 3.0b currently supports Oracle 10g?
Moreover, does anybody know of any BW version currently supporting this Oracle 10g version? or by when does SAP plans to support it and which BW version(s) they plan?
Thank you!
Regards,
Mario Vallejo

Hi Dinesh,
Sorry but I could't find it...
I also searched by "Oracle 10g" bot no related link was found.
Any hints on how to look for it? or more specific URL...
I really appreciate it!

SAP Note 378648 - Offline backup support with Oracle Fail Save

I am trying to implement SAP Note 378648 - Offline backup support with Oracle Fail Save, but am unsure about part of the solution....
Basically, I have to add several parameters into the Environment Variables of the MS Clustered Servers running Windows Server 2003 for the user xidadm...
Fairly straight forward apart from one parameter....
BR_OFS_DOMAIN=<domain>
I am unsure what is required/meant by domain. Can anyone shed some light??

Those are environment variables of the Windows user who is running brbackup; usually this is SAPService<SID>.
You have to set this variables the same way as you set ORACLE_HOME and so on.
(I am not sure about the details; never worked with MS cluster.)
hope this helps

Oracle Adapter for SAP that supports Integration with SAP 6.0??

Hi,
I am working currently with Oracle Adapter for SAP with SAP 4.6.
But my company is looking for upgrading the Enterprise SAP system to 6.0.
Do we have Oracle Adapter for SAP that supports SAP 6.0? Please let me know if anyone has already worked on this?
Thanks,
Sasi Bhushan

Sasi,
There is a new MySAP adapter with 10.13.1 and above to support ECC 6.0. Please see the following section in the 10.1.3.1 adapter release notes:
12.4.1 MySAP ERP Versions and APIs
The following MySAP ERP platforms are supported by OracleAS Adapter for MySAP
ERP:
■ SAP R/3 Enterprise 47x100
■ SAP R/3 Enterprise 47x200
■ MySAP ERP Central Component (ECC) 5.0, deployed on SAP NetWeaver 2004
■ MySAP ERP Central Component (ECC) 6.0, deployed on SAP NetWeaver 2004s
■ SAP Java Connector (SAP JCo) Version 2.18.
For the current release status of the SAP Java Connector, refer to SAP Note #549268
in the SAP Service Marketplace.
Release versions may vary by product component. In addition, SAP functions may
vary by SAP product version and support package.
Note: The OracleAS Adapter for MySAP ERP supports only the versions listed above.
It is not recommended to use the OracleAS Adapter for MySAP ERP with older
versions of SAP R/3. If you plan to use the adapter with older versions of SAP R/3 for
example SAP R/3 4.6C, prior approval from iWay Software Product Management is
required.

IE 7 Officially released ! When would SAP start supporting IE7?

To SAP EP Team,
Now that IE7 have been officially released, when would SAP start supporting IE7?
Currently we are in EP6.0 SP 15. KM SP 15. Will there be any patches for supporting IE7? If so when would that be available?
Thanks,
Deepak

FYI,
Those of you that are faced with impending support for IE7 may like to know that Microsoft has released a workaround that will allow IE7 to "run as" IE6.
The download is located under the IE7 Release Notes, under the heading: "Accessing websites that only work with Internet Explorer 6"...
Follow this link http://msdn.microsoft.com/ie/releasenotes/default.aspx
then
http://www.microsoft.com/downloads/details.aspx?FamilyID=9517db9c-3c0d-47fe-bd04-fad82a9aac9f&DisplayLang=en
Click "continue" to validate, download, and install the circumvention. The process will leave a shortcut on your desktop that (when clicked) will start IE7 in IE6 mode.
Click the "Change Settings" button and IE7 will be launched in IE6 compatibility mode for the duration of that session.
We've tested against our WebDynPro and HTMLB problems and this circumvents them all so far...

SAP SRM Prod with Oracle DB and AIX 5.3 Performance Issue.

Hi Basis Gurus,
Today my SAP PRD system all of a sudden was running slow and users had difficulties executing TCodes as it took minutes before the screen appeared.My system is SAP SRM 4.00, Oracle Release 11.2.0.1.0 and AIX 5.3.
From Basis point of view , we noticed that all the work process were hanged due to RFCs' occupying it.Couldnt investigate further on the system as we needed to restart asap because users needed to log on. A quick check on SICK shows no errors.What we managed to find out is that we needed to check this parameter below and set it accordingly:-
rdisp/rfc_min_wait_dia_wp:-
Definition
Number of work processes kept free for other users.
Use
This parameter is used to reserve a number of dialog work processes for dialog mode. It prevents parallel RFCs from occupying all the processes.
The parameter rdisp/wp_no_dia specifies the absolute number of dialog work processes.
Unit: number of dialog work processes
Default value: 1
Example
If 10 dialog work processes are configured for the instance (rdisp/wp_no_dia = 10) and the parameter rdisp/rfc_min_wait_dia_wp = 3 is set, parallel RFCs can occupy a maximun of 7 dialog work processes. Three dialog work processes always remain free for dialog mode.
There are 20 DIA processes in our system, perhaps reserving a minimum of about 5 work processes for DIA users will be useful via the parameter.
So my first question would be is there any other suggestions besides adjusting the mentioned parameter above in order to ensure that no work processors going into hang state due to RFCs' occupying it as this issue always happens at the end of the month only when there are massive users accessing it.
When we went for a restart of the system we encountered another issue. Steps to the issue are as below:-
1) Did a proper shutdown of Oracle and SAP.
2) When we start using startsap script, it doesn't start DB so we started DB manually but listener was having problem
    so we stopped all.
3) We also did a cleanipc, it too throws below error:-
sidadm> cleanipc <systemno> remove
               exec(): 0509-036 Cannot load program cleanipc because of the following errors:
               0509-130 Symbol resolution failed for cleanipc because:
               0509-136   Symbol memmove (number 106) is not exported from
               dependent module /usr/sap/sid/SYS/exe/run/libsapu16.so.
               0509-192 Examine .loader section symbols with the
               'dump -Tv' command.
4) Also the Listener file has no contents,it's null file.
5) This is another error :-
    exec(): 0509-036 Cannot load program /oracle/sid/112_64/bin/tnslsnr because of the following errors:
    0509-150   Dependent module /oracle/sid/112_64/lib/libttsh11.so could not be loaded.
    0509-101   The module has too many section headers
    or the file is damaged
The libttsh11.so file was empty dated 25th timestamp as below in PRD:-
-rw-rr    1 sid   dba               0 Nov 25 07:12 libttsh11.so
Further checking has let me to understand this is an Oracle Bug from this link:-
http://gavinsoorma.com/2009/12/11-1-0-6-clusterware-upgrade-to-11-1-0-7/
This Oracle bug only happens in an Upgrade time and how could this happen to my Production system during a restart process.
Also this system was restarted during the last weekend's maintainance window and it came up with no issues.
6) We copied over the libttsh11.so from our QA environment to PRD and did a Startup:-
-rwxr-x---    1 sid   dba        65967496 Nov 25 07:40 libttsh11.so (This is the copied over file from QA)
7) After Startup everything has been in order till now.
My second question is what went wrong with the libttsh11.so file. How could it be 0 size in PRD when no signs of changes had happen to the PRD system. Is this a proven Oracle Bug or something else since I have never encountered anything like this before. Hope all the Gurus here could shed some light into my 2 questions as I am looking for positive answers.
Thank you.
Regards,
John

Hi,
Firstly I would suggest you to upgrade your database from Oracle Release 11.2.0.1.0 to Oracle Release 11.2.0.2 . This is the recommended Oracle 11g database version for SAP solutions. Many of your problem will get resolved with it.
Question 1:
So my first question would be is there any other suggestions besides adjusting the mentioned parameter above in order to ensure that no work processors going into hang state due to RFCs' occupying it as this issue always happens at the end of the month only when there are massive users accessing it.
For immediate resolution the approach you have followed is correct viz limiting number of dialog processes for RFC. Secondly you need to analyze why RFC processing takes so much time. You need check which programs are getting executed by those RFC.
Generate EarlyWatch report for more detailed view
Question 2:
My second question is what went wrong with the libttsh11.so file. How could it be 0 size in PRD when no signs of changes had happen to the PRD system. Is this a proven Oracle Bug or something else since I have never encountered anything like this before.
The libttsh11.so library cannot be found in the related directory.
Cause
The file system is mounted using CIO option, but per Note 257338.1 Direct I/O (DIO) and Concurrent I/O (CIO) on AIX 5L, an ORACLE_HOME on a filesystem mounted with "cio" option is not supported.
Such a configuration will cause, installation, relinking and other unexpected problems.
Solution
Disable the CIO option on the filesystem.
References
NOTE:257338.1 - Direct I/O (DIO) and Concurrent I/O (CIO) on AIX 5L
Hope this helps.

SAP R/3 on Oracle / Solaris / ZFS

Hello,
My unix administator is planning on upgrading to a new OS environment to Solaris 10 with ZFS. We currently run SAP R/3 4.6C kernel / Oracle 9i on Solaris release 5.8 and I would like to know what would be the path to take from here. Does SAP R/3 4.6C or even 4.7 Support ZFS and what about Running Oracle 10g datafiles on a ZFS system for the SAP Database.
Any support is appreciated,
Arun

Oracle doesn't certify any more filesystems or certain Storage Systems (see Oracle Metalink 403202.1 - Zeta File System (Zfs) On Solaris 10 Certified/Supported By Oracle) but it's supported to run on them
We run several databases (Oracle and non-Oracle) on ZFS - and combined with zones it's GREAT to consolidate systems.
Check http://www.sun.com/software/whitepapers/solaris10/zfs_veritas.pdf for a comparison between VXFS and ZFS.
The SAP system itself is agnostic about the underlying filesystem.

Memory hot plug supported in Oracle linux 6.0 ?

hi,
I am testing Oracle Linux 6.0 on a vm, I tried to hot add memory, but i noticed that the respective modules like acpiphp and acpi_memhotplug not present.
Also i got the below information from the site, http://blogs.oracle.com/wim/2010/10/playing_with_sr_iov_in_oracle.html
"----------To enable pci hotplug in the guest, please do the following :
in the guest you have to load both pciehp and acpiphp
you can do this easily by doing :
**echo "modprobe pciehp" >> /etc/rc.modules
echo "modprobe acpiphp" >> /etc/rc.modules
chmod 755 /etc/rc.modules**
note - this is for testing purposes only. We do not currently have official support in the product for this.--------".
I tried doing the above mentioned procedure, then also the mem-hot plug is not working.
So I feel mem-hot plug is not supported.
Can any oone confirm me about this.

SAP DDIC support for Index - Limitation of 16 fields

As some of you know DB2 Index advisor at times recommends indexes with more than 16 fields, Unfortunately SAP doesn't support it creating them from SAP DDIC level (SE11).
We had a recent issue in OLTP system where BW extractor on FAGLFLEXT wasn't performing as expected for a delta run. SAP OSS Support wasn't of much help. We already had an index on TIMESTAMP field, unfortunately the SQL generated by BW Delta run wasn't using TIMESTAMP field for the DELTA run. DB2advisor recommended index for the bad sql resolved the issue for us.
Is there a DB6 DBSL related profile parameter to remove the max index field limitation ?

Thanks Frank as always for quick response.
I have also got an official response from SAP DDIC Development team
Here are the details for others who want to know -
Regarding your question why DDIC supports only up to 16 index fields:
Our applications are supposed to run on several database platforms.
In order to guarantee portability of applications across all of these
DB platforms, we have to set the limits accordingly. Unfortunately,
there is at least one platform that does only support up to 16
index fields and thus we cannot support more in the DDIC. We can only
increase this limit when all supported DB versions - and this might be
very old ones because we cannot force customers to always migrate to
the newest DB version - support this.

How to incorporate a Language that is not supported in Oracle Portal

Hi,
I want to know the preferred way to add support for a new language in Oracle Portal.
If a language is not supported in Oracle Portal, how I can add the content for that language in the Portal?
Please advise.
Best Wishes.

I've seen this in a statement of direction presentation as an enhancement for R11. So this should be a R11 feature. In the meantime you might investigate the NLS views and tables and try to find a way to extend this. BUT just in an emergency case and you have to know that is not supported (also you may lose support in general for this installation when hacking the repository). So I cannot recommend this with a clear conscience. You have to know exactly what you're doing.
You can also open a SR to get an official statement from support. Maybe there's a note for this.

How to configure SAP 4.7 to Oracle 9i Real Application Cluster ?

We are using SAP 4.7 running on Oracle 9i with HP-UNIX clustering.
If we change our existing SAP 4.7 for Oracle 9i Real Application Cluster, is it very complicated ?
Do we need to re-install SAP and Oracle ?

Both 4.7 and Oracle 9 are already out of support.
If you plan to use RAC then I'd first upgrade the application and the database and then implement RAC. You won't have support for your environment without additional costs.

Oracle DataGuard Logical Standby

Hi , I'd like to know what are the premisses to make a standby logical replication.
I have two environments (production and standby) with different number of processors and storage.
I'd like to know if it's possible to create data guard solution with these two environments and what are the premisses that I need aware to install the solution.
Thanks in advance.

Hello;
Yes the storage ( as long as you have enough space ) and cpu don't matter.
You can use hardware that's quite a bit different and it will work fine.
You can also create a Logical Standby fro a physical standby.
These notes may help :
NOTE 413484.1 - Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration
Mixed Oracle Version support with Data Guard Redo Transport Services [ID 785347.1]
Logical Standby's don't seem to be very popular and the support base suffers because of this. I would consider a physical standby with Active Data Guard if costs allow.
Active Data Guard makes an excellent "Reader" database plus I believe your switchover and failover options are much better than a Logical Standby.

Forte support of Oracle and VMS

We need to deploy a Forte V2.0.F.2 application on VMS V7.1 and Oracle
V7.3.2
Forte does not officially support this configuration!
Anyone out there tried it, and what were the results?

Hi Jürgen,
Window Server 2008 is not supported at present. Oracle 11g should be supported - I believe a few of my clients are using version 11g.
All the best,
Luke
