Hi,

I have to upgrade Kernel for our ECC 6.0 system. Our database is MS SQL. & it is running on windows.Currently we are on kernel95

Latest available kernel in Market place is dw_160-20001354.sar . As per I know we have to apply sapexe & sapexedb.

1. Please let me know the procedure that How to apply kernel

2. what is the pre-requisite

3. what is post upgrade steps

4. if I will apply only dw_160-20001354.sar.I think we have to apply only this file.

Points for helpful answer.

Dear

1) set system message

2) download kernel (sapexe, sapexedb), tp and R3trans (check unicode of non unicode kernel using disp+work -version)

3) stop SAP dialog instances

4) stop SAP central instance + db

5) stop saposcol

6) stop Oracle listener

7) stop startsapsrv

😎 check if all processes are stopped

9) clean shared memory (cleanipc <instancenumber>)

10) backup old kernel

11) copy SAPCAR to SAPCAR<new name> (else you will try to overwrite SAPCAR by the new SAPCAR of the kernel files)

12) run saproot script (on unix saproot.sh <SID> <DBSID>)

13) startup listener

14) startup central instance + db

15) startup dialog instance

16) check system running correctly (transactions SICK,SM21,SM50 for example)

17) remove system message

Reward points if useful

Kind regards

Hi

You need to download sapexe and sapexedb both the files, as one is database independent and database dependent files. Extract both the files and copy data into common Run directory.

I do not have idea about the dw file mentioned here.

dw_160-20001354.sar is just the disp+work package, you need to download both parts of the kernel as stated above

Dear

If you need a specific level of d+w you can first apply the latest SAP kernel (or the latest -1 if it just came out and you don't want to take any risk that bugs are present)

Once you have applied the packages I stated at point 2, you can see the version of your dispwork by using command dispwork -version

If the version is not high enough for your needs and a newer version is available you can download it and apply it.

2) download kernel (sapexe, sapexedb), tp and R3trans (check unicode of non unicode kernel using disp+work -version)

Please reward points for the info provided

Kind regards

Hi..

In brief I would say:

1.shutdown your SAP instance.

2.Extract the new kernal files using SAPCAR utility.

3.Rename you old kernal (RUN) folder..eg: "run old"

4.Copy& paste the newly extracted file in the new folder with name "Run" (in same location as the old Run folder)

Cheers..
