2. when open cdsdoc
/tools/ic610/tools/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory

Goto /CDS_ROOT/tools/bin/cdsdoc and edit cdsdoc
Search and find "LD_ASSUME_KERNEL=2.2.5" , it should be at some "if" structure. Looks like they use IF structure for some x86 and AMD adaptive
Change "2.2.5" to your KERNEL version
DONE

3. error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory
go to /usr/lib
ln -s libstdc++-libc6.2-2.so.3 libstdc++-libc6.1-1.so.2
