Question

Hi,
The system is at kernel patch 75,so I was applying the kernel patches by extracting the .SAR files into the /usr/sap/
4 ETW000 R3trans was called as follows: R3trans -x

2EETW169 no connect possible: "maybe someone set invalid values for DIR_LIBRARY ('/usr/sap/SDV/SYS/exe/run') or dbms_type ('ORA')"
So,the DB is unable to start & as a result,SAP system isn't available.
Request your help.
Thanks

The problem is, that you should not use the same SAPCAR to extract in the same directory since it can't overwrite itself. You can use a relative path e. g.
cd \usr\sap\<SID>
mkdir newkernel
cd newkernel
\usr\sap\<SID>\exe\SAPCAR -xvf <kernel>
Then
ren exe exe.old
ren newkernel exe
