Hi Guys,
I am having problems while creating a Db2 instance.
I have installed Db2 on linux but when I try to create an instance I get below error. Need your help in resolving the same. Error has something to do with entries in /etc/services or .rhosts or db2nodes.cfg file.
I always thought that entires for db2instance automatically comes in /etc/services files when we create instance. :-(

[root@aaaaaaaaa instance]# ./db2icrt -u db2fenc1 db2inst1
/opt/ibm/db2/V9.5/instance/db2iutil: line 4700: 30757 Segmentation fault ${DB2DIR?}/instance/db2isrv -addfcm -i ${INSTNAME?}

Just curious as to the following:

1. Do you really want 32-bit Linux?
2. Why didn't you specify the port in the db2icrt command (-p option)?
3. Why are you installing Fix Pack 0? You can install the latest fixpack and then just apply the license from the original media you have.
