Hi Shishir,

Since you upgrade from kernel 620 to kernel 640, please check note #521230 before doing this, since, depending on your platform, your new kernel will no longer be linked to the Oracle 8 client.

Many people are not aware of the fact that they actually have the combination kernel 620/Oracle 8 client/Oracle 9 database in their system. In case your old kernel was linked to Oracle 8 and you do not have the Oracle 9 client installed, the SAP workprocesses will most likely not be able to connect to the DB after the kernel upgrade.

Best Regards,

Michael

Most of your questions are answered in SAP Note # 556994. Please check.

Hi,

You can also say the same as Andreas about the Oracle upgrade.

9.2.0.8 is the latest patch set release for 9i and oracle will only create new patches for this patch set level.

If you are in a lower level and you get an unknow error you will be asked to upgrade to the latest patch set as the bug fix will be created for this.

the <b>most obvious reason: kernel 620 is no longer supported</b> by sap...only 640 (and of course 700) is so, when yoou're having troubles and sap advises you to upgarde the kernel (which thy always do if you're not using the most current one), you'd have to do it anyway...

kernel upgrades will fix problems at the basis of the sap system - the executables, like disp+work, tp, r3trans and so on...these executables will be develeoped and improved regarding stability and functionality...so, it's always good advice to keep them current

Hello Andreas

Many Thanks For Your Prompt Reply

I agree with you but i want my answer is more depth

there are two files we are downloading from service.sap.com

- SAPEXE.SAR: all database independent executables and libraries

- SAPEXEDB.SAR: database specific executables

after uncar those files we replace the new files with old files that is Run Folder

Can You Explain The role of those files which we are replacing

Many Thanks In Advance, waiting for your prompt reply

Hi Shishir,

Can u pls let me know the procedure of Kernel Upgradation in detail, if possible with screenshots.

Thanks in Advacne, waiting for your prompt reply

Sree.

[andreas_herzog]

the role? this is quiet too much to explain

(nearly) all files of the run directory (= kernel) will be replaced...sapexedb consists of database related files, such as dbslibora (database library) or the br-tools (brarchive, brrestore etc.)...to get all information in depth, have a lookup at sapnet alias NOTES..maybe you'll find more

<u>most important ones are:</u>

disp+work -> dispatcher/work process

tp -> transport & puts (used for transports of all kinds...sap upgrade as well)

r3trans -> is needed to make several checks (such as r3trans -d) and will be used for transporting

saposcol -> sap operating system collector (will collect os data...have a look at ST06)

brtools -> used for oracle db administration

dpmon -> dispatcher monitor on os level

sapseculib -> sap crypto library

sapcar -> sap's archiving tool

saprouter -> implements an application layer gateway (a tine firewall)

r3ldctl -> R3 Load Control (used for system copies)

r3szchk -> R3 size checker (used to calculate target database size)

r3load -> used to import/export data
