You might need to enable network file system (NFS) services when configuring the High Availability Disaster Recovery (HADR) or Database Partioning (DPF) DB2 features. For example, with HADR, you might want to set up a slave database that shares a backup with the master database through NFS.
These commands should enable NFS services on most distributions of Linux:
sudo /sbin/chkconfig nfs on sudo /sbin/chkconfig nfslock on sudo /sbin/chkconfig rpcgssd on sudo /sbin/chkconfig rpcidmapd on sudo /sbin/chkconfig portmap on sudo /etc/init.d/iptables restart sudo /etc/init.d/nfslock restart sudo /etc/init.d/portmap restart sudo /etc/init.d/nfs restart
Some of the services might not exist on your distribution. Additional steps may be needed.
IBM Smart Business Cloud for Test & Development might be one of the environments where you’d have to do this.
