Clarification regarding kernal upgrade

Hi Experts,
In our production system (OS:AIX) we have database and central instance in host A and the dialog instance on host B.
As per my understanding I need to extract the kernal patch in
hostA : DVEVMGS00/exe and SYS/exe/run
hostB : D01/exe.
I have never done a kernal upgrade in this type of schenario. Kindly confirm if this process is right or anything else I need to do.
Thanks and Regards,
Amit Jana.

Hi,
Plzz don't do like that HOST -A & HOST- B.
your central instance is there in HOST-A. Then do like this.
1. Go to market place download the latest kernal.
2. Stop your Sap Application Central (HOST-A) & Dailog (HOST-B) aslo.
3. Take the backup of u r kernal dir that is RUN dir in HOST-A
    backup means copy of run dir..
4. Then uncar the downloaded files in HOST-A.
5. Copy the all uncared files in RUN directory in HOST-A no need to copy HOST-B.
6. Than start u r central instance (HOST-A).
7. After complted successfully server up, then start u r Dailog instance (HOST-B).
8. Automatic kernal will be exfected. No need to copy kernal in Dailog.
Plzz do this i was already did my company. It working successfully.
                               Thanks & Regards,
                                  Sumanbabu.b

I need kernal upgrade on hp unix cluster ECC6 process step to step

Hello,
I need kernal upgrade procedure on hp unix cluster ECC6 in step to step
Please help me .
Regards
Mahesh

Hi,
If its a cluster or single instance, the procedure is the same.
As a thumb rule always execute the program RSPARAM from se38 and find the directory structure of the parameter DIR_CT_RUN.
The default value is generally /usr/sap/SID/SYS/exe/run
Download the SAPEXE<NO>.SAR and SAPEXEDB<no>.SAR and extract i in the above directory.
Before you do it make sure thats:
Stop the SAP R/3 resource in the cluster. Leave the SAP disk online.
Replace the Kernel
Start the instance
Replicate executables in the c:windowssapcluster or c:winntsapcluster (on both nodes)
You are done
Thanks Nirmal

Planning upgrade LCA build 41.12 to 41.17 + kernal upgrade

Can we do the Service pack and kernel upgrade without a manual of- and re-load of data? All notes states that an initialize is not needed a simple restart is sufficient.
My idea is:
1)       backup live cash
2)       Stop LCA
3)       Install service packs and kernel upgrade
4)       Restart LCA
5)       Reload data from backup
BR/Flemming Rønhø

Hello Flemming,
As I understood you - you have the LCA build 12 PL 002/liveCache version 7.5.00.35
On SCM 4.1 system & you are planning to run the upgrade to LCA build 17 PL 002/liveCache version 7.5.00.44 using the SAP Note 1070304 .
=> please proceed as described in SAP Note 713381 ("Importing liveCache version...") to import SCM 4.1 LCA Build 17 patch level 002 and the corresponding liveCache Kernel 7.5.0 Build 044.
If I missunderstood your question, please give more information about your project "Planning upgrade LCA build 41.12 to 41.17 + kernal upgrade". Please also let me know:
-> Wat is the version of your system?
-> Are you SAP customer?
-> Do you have the ONEDB database instance?
-> There is SAP link with helpful information & reference to the notes at
      service.sap.com/liveCache-> Release Information -> SCM 4.1 - SAP liveCache technology 7.5.0
     Is it what are you looking for?
Thank you and best regards, Natalia Khlopina

Clarification regarding Shadow Table

Hi All,
Clarification regarding Shadow Table. FKK_GPSHAD is a shadow table that belongs to Business Partner. The doubts that i have is
What is Shadow Table?
What is the purpose of Shadow table?
Is it correct way to update Shadow table Manually(Not using any BAPi etc....)?
Is any BAPI available to update The above mentioned Shadow table.
Thanks in Advance..

Reclustering InfoCubes:
With reclustering, the InfoCube fact tables are always completely converted. The system createsshadow tables with a new clustering schema and copies all of the data from the original tables into the shadow tables. As soon as the data is copied, the system creates indexes and the original table replaces the shadow table. After the reclustering request has been successfully completed, both fact tables exist in their original state (name of shadow table) as well as in their modified state with the new clustering schema (name of original table).
You can only use reclustering for InfoCubes. Reclustering deactivates the active aggregates of the InfoCubes; they are reactivated after the conversion.
Reclustering DataStore Objects
Reclustering completely converts the active table of the DataStore object. The system creates a shadow table with a new clustering schema and copies all of the data from the original table into the shadow table. As soon as the data is copied, the system creates indexes and the original table replaces the shadow table. After the reclustering request has been successfully completed, both active tables exist in their original state (name of shadow table) as well as in their modified state with the new clustering schema (name of original table).
You can only use reclustering for standard DataStore objects and DataStore objects for direct update. You cannot use reclustering for write-optimized DataStore objects. User-defined multidimensional clustering is not available for write-optimized DataStore objects.
Pls chk this thread:
Shadow Table?

Why do we do kernal upgradation in central instance only

Experts,
I have a question. Why do we do kernal up gradation in central instance only? what about other instances? How the up gradation takes place in other instances?
points will be awarded to all helpful answers.
Thanks in advance.
Rajesh

Hi,
Whatever the other two friends have explained is correct. We do kernal upgrade only on CI when the Operating systems of the CI and the Application Instances are same.
if the CI and AI are in different operating systems then we may have to upgrade kernel in both CI and AI.
Sapcpe.exe would synchronize the kernel only when the SAP systems have homogenous OS.
Reward points if useful.
Thanks,
sree

Hello Experts,
We are running SAP R/3 4.5B version, now we are planning to upgrade to version 4.7 . At present we are going through the release notes of both the versions and talking to the experts regarding this upgrade.
As this is the best foram for SAP, could some body tell us technically what are the enhansments in version 4.7. and one very important questions is, if we upgrade to version 4.7 do we need to make any kind of changes in the current running ztables and programs, particularly Enhansments, ALE/IDOC configurations, our batch jobs etc..
I will really appreciate ur views.
Thanks in advance.
Regards,
Hardik

Hi ,
Thx for ur reply.
That is true we are going to buy upgraded license.
We even understand that 4.7 puts some additional features.
How ever we need to make sure that, we don't need to change any of our current programs and database structure. Pl give me ur views..

what these above refere to.
Please clarify me in this.

that about External Procedure, If you don't use "External Procedure" you can remove it, by the way you should avoid default configure.

Some clarifications regarding Aironet settings

Hi,
i need some clarifications regarding configuring Aironet stand-alone AP (in this case AIR-LAP1131AG).
Under Security->SSID Manager:
what is the purpose of Network ID?
Under Guest Mode/Infrastructure SSID Settings - what is the purpose of Set Infrastructure SSID?
and Force Infrastructure Devices to associate only to this SSID?
Cheers,

Assign a Service Set Identifier (SSID) to each VLAN configured on the AP. SSIDs enable endpoints to select the wireless VLAN they will use for sending and receiving traffic. These wireless VLANs and SSIDs map to wired VLANs. For voice endpoints, this mapping ensures priority queuing treatment and access to the voice VLAN on the wired network

Needs Clarification Regarding Segments and Datafiles

Hi,
I want clarification regarding Segments, Datafiles and extents.
As we know that A segment is made of one or more extents and extents are composed of one or more datablocks in the HD.
Since all data are store in Datafiles which are composed of extents and datablocks. I want to know weather a table(Segment) can span to multiple datafiles or in a sigle datafile.

Kernal Upgrade

Dear All
Can anyone please tell me what Other location we can put the kernal file while upgrading the kernal apart from usr\sap\sys\exe??
Regards,
Manmohan

Hello Manmohan
Please give more information if you want people to help you out.
Which SAP Product, which Release version and so on.
If you are working with a recent SAP Product version I would advise you to patch the kernel using JSPM (in case of dual stack SAP system of Java based SAP system). JSPM can perform the neccesary steps for you.
If you are working on an ABAP only SAP system you only need to update the kernel files in the kernel directory itself.
Kind regards
Tom

License key question with regards to upgrading from 7/8.1 to 10

Hi, I hope I've posted my question in the right area of the forum:
I understand that Windows 10 will be a free upgrade for Win7/Win8 users.
That's really wonderful but I was wondering what the exact mechanism with regards to our 7/8 license keys. Here's a couple examples to clarify my question:
first, example: I have Windows 7 Pro license and say I upgrade to 10 within the first year. Let's say I need to reinstall Windows after that first year is finished will I still be able to use that same license key I used to upgrade 7 to 10 to install a fresh
copy of Windows 10 or will I need to purchase a new license because the year is elapsed?
Here's another scenario. I upgrade to Windows 10 from 7 and after trying Windows 10 for while, I decide to uninstall 10 and go back to 7... because I'm crazy like that.... Will I be able to use my original Key for Windows 7 or is the upgrade a one way road:
where the 7 key turns into a Windows 10 key and can no longer be used to activate Windows 7?
Thanks for the feedback!

Hi Momashi
Here's another scenario. I upgrade to Windows 10 from 7 and after trying Windows 10 for while, I decide to uninstall 10 and go back to 7...
because I'm crazy like that.... Will I be able to use my original Key for Windows 7 or is the upgrade a one way road: where the 7 key turns into a Windows 10 key and can no longer be used to activate Windows 7?
If you Upgrade to Windows 10 and do not like it, for whatever reason.
Before you upgrade to Windows 10.
Create an image of windows 7 to an external HD and a recovery CD, using windows 7 Backup and Restore.
You can re-install windows 7 in the SAME SYSTEM using the recovery CD without using a key.
Hope it helps
Where did you get your outlandish information about a Windows 7 key turning into a Windows 10 key? Nothing in the past has ever happened like this before, so what makes you think it will happen with Windows 10?
My Windows ME did not turn into a Windows XP key!
My Windows XP key did not turn into a Windows Vista key!
My Windows Vista key did not turn into a Windows 7 key!
And so on!
