sql1032n sql6048n Db2start Not start DB2 modify hostname

This afternoon, the virtual machine on the Linux hostanme to get rid of the results of the start of DB2 when the error occurred
sql6048n A communication error occurred during START or STOP DATABASE MANAGER processing.
SQL1032N No Start Database Manager command was issued. sqlstate=57019



Through DB2? Sql1023n learned that communication dialog failed

We need to modify the Db2nodes.cfg file or the Hosts file under DB2

What is the content of the db2nodes.cfg and hosts files?
VI db2nodes.cfg

Vi/etc/hosts


Obviously you can see that localhost in db2nodes.cfg is not defined in the Hosts file
So we need to change the localhost in the db2nodes.cfg to the Linux-vm23.localdomain in the Hosts file.


Next start DB2 normal start up!
