EBS Install problems

During my 11.5.10 install on Redhat ES 3.0, I experienced some problems.
1. After installing the APPL_TOP (almost at the end of the install....), the installer wants to run autoconfig. But the installer hangs and when checking the logfile, the following error occurs..
libdb.so.3: cannot open shared object file: No such file or directory
I searched Metalink for a solution and found out that the compat-db-4.1.25-6.i386.rpm package should be installed. After installaing the package, the problem was not solved...Using google I found out that someone had tried to relink the libdb.so.2 to libdb.so.3. Libdb.so.2 is present in the /usr/lib directory, so lets give it a try. After generating the link using ln -s, I restarted the rapidwiz (./rapidwiz -restart) and this time the installer continued !!!
2. The second problem occured at the post install checks by the installer. According to the installer my *.dbc file in the $FND_TOP/secure was corrupt. Seemed kind a strange, since the rapidwiz did create the dbc file in the first place. When looking at the dbc file, I noticed that the dbc file the installer used to connect to the databaseas in fact no more then a template !!! The rapidwiz never produced a valid dbc file, which I coukd use to connect to my 11i database. But I never saw an error anywhere ?? I decided to run autoconfig myself and find out where autoconfig is going wrong. Autoconfig ended with 'no errors' ??? The autoconfig proces did create a dbc file this time. I ran the post install check again, and everything was fine.
3. The last problem was a FRM-92050 error when trying to connect to the forms server.
This error was solved using the note 299187.1 from Metalink. I had to set two variables, the LD_ASSUME_KERNEL (2.4.19) and the $LANG (empty).

So, now my EBS 11.5.10 is working and I will look for more problems.
