If the > ulimits on the system are not sufficient, then sqlci start hangs. The > customer has to kill sqlci and then kill all the processes in flight. > This happens when you perform the build instructions and choose the > "install_local_hadoop" option. The Trafodion Installer should already be > checking for this situation. > Perhaps add a check before sqlci starts to make sure the correct limits are > set. > Recommended limits: > ulimit –a > core file size (blocks, -c) 1000000 > data seg size (kbytes, -d) unlimited > scheduling priority (-e) 0 > file size (blocks, -f) unlimited > pending signals (-i) 515196 > max locked memory (kbytes, -l) 49595556 > max memory size (kbytes, -m) unlimited > open files (-n) 32000 > pipe size (512 bytes, -p) 8 > POSIX message queues (bytes, -q) 819200 > real-time priority (-r) 0 > stack size (kbytes, -s) 10240 > cpu time (seconds, -t) unlimited > max user processes (-u) 267263 > virtual memory (kbytes, -v) unlimited > file locks (-x) unlimited -- This message was sent by Atlassian JIRA (v6.3.4#6332)
