Error description
In Red Hat Enterprise Linux 7, systemd replaces upstart as the default init system. The DB2 fault monitor does not support the systemd init system. During execution of db2fmcu, instead of expected systemd configuration, db2fmcu creates an entry in the deprecated /etc/inittab file. You can observe symptoms in OS strace. Once you execute: ./db2fmcu -u -p /opt/ibm/db2/V11.1/bin/db2fmcd In the trace snippet you can see: readlink("/etc/inittab", 0x7ffff54f82e0, 4094) = -1 EINVAL (Invalid argument) access("/etc/.inittab.lock", F_OK) = 0 open("/etc/.inittab.lock", O_WRONLY|O_CREAT, 0644) = 3 fcntl(3, F_SETLKW, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}) = 0 readlink("/etc/inittab", 0x7ffff54f8190, 4094) = -1 EINVAL (Invalid argument) access("/etc/inittab", F_OK) = 0 ... The goal of this APAR is to introduce support for systemd by the DB2 fault monitor.
Local fix
Create file: /etc/systemd/system/db2fmcd.service with following content: [Unit] Description=DB2V111 [Service] ExecStart=/opt/ibm/db2/V11.1/bin/db2fmcd Restart=always KillMode=process KillSignal=SIGHUP [Install] WantedBy=default.target Next execute: systemctl enable db2fmcd systemctl start db2fmcd
