I was trying to upgrade from 188.8.131.52 to 11g, oracle recommended to upgrade it indirect way, from 184.108.40.206. to 220.127.116.11 then to 10g and 11g.
I got a 18.104.22.168 patchset( 3109399) for windows2003.
Checked its read me file , and brought down services and copied all the files of patch to the OLD ORACLE HOME/bin
Now to run the scripts like catadt.sql, i need to login to datABASE, when i give sqlplus it give error likeThe procedure entry point lxhlcmod could not be located in the dynamic link library oranls9.dll
Sorry I couldnt respond quickly, because here in my area, we lost the current for many hours...
I agree with you after checking the doc you've referenced, however I have already followed the oracle doc saying to upgrade 22.214.171.124 to 126.96.36.199( Unfortunatly this patchset as per README file needs to directly copy to ORACLE HOME directories rather overwrite them) which i already did.
I am not able to login to database now to run the few scripts, error is
The procedure entry point lxhlcmod could not be located in the dynamic link library oranls9.dll
