docker - dashDB local MPP deployment issue - cannot connect to database -


i facing huge problem @ deploying dashdb local cluster. after successful deployment following error comes in case of trying create single table or launch query. furthermore webserver not working in previous smp deployment.

cannot connect database "bludb" on node "20" because difference between system time on catalog node , virtual timestamp on node greater max_time_diff database manager configuration parameter.. sqlcode=-1472, sqlstate=08004, driver=4.18.60

i followed official deployment guide, followings doublechecked:

  • each physical machines' , docker containers' /etc/hosts file contains ips, qualified , simple hostnames

  • there nfs preconfigured , mounted /mnt/clusterfs on every single server

  • none of servers signed error @ phase "docker logs --follow dashdb" command

  • nodes config file located in /mnt/clusterfs directory

after starting dashdb following command:

docker exec -it dashdb start

it looks should (see below), error can found @ /opt/ibm/dsserver/logs/dsserver.0.log.

# --- dashdb stack service status summary --- ##################################################################### redirecting /bin/systemctl status slapd.service

after several redeployment nothing has changed. please me in doing wrong.

many thanks, daniel

always make sure ntp service started on every single cluster node before starting docker container. otherwise take no effect on it.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
