Hello,

I just gave this command to convert the instance to 64 bit:

./db2iupdt -w 64 instance1

the command executes successfully but when I try to start the db, I get this:

db2start
db2start: relocation error: /opt/IBM/db2/V8.1/lib64/libdb2icuglue.so.1: symbol _ZTVN10__cxxabiv120__si_class_type_infoE, version GLIBCPP_3.2 not defined in file libstdc++.so.5 with link time reference


Am i missing a step? Thanks for the help in advance!

Try to recreate a link to usr/lib file...
Execute as root this command
db2rmln
and
DB2DIR/cfg/db2ln
