Vertica Request for X percent of Y CPUs rounds to zero CPUs


when trying to create a resource pool using some % of the total CPUs you may encounter this error:

Vertica Request for 10% percent of 4 CPUs rounds to zero CPUs \n (6006) (SQLExecDirectW)

 why?
since 10% of 4, rounded by vertica to 0. and you can allocate 0 CPUs to a resource pool

how to fix:
fix % to be at least 25% or use static allocation of CPU set to a resource pool

mount.nfs: backgrounding

if you face this kind of error with your remote NFS: [root@Vertica000 ~]# mount /files/application/Rremote3 mount.nfs: backgrounding "10.0.0.2:/files/application/remoteFiles" mount.nfs: mount options: "bg,hard,nointr,rsize=65536,wsize=65536,tcp,actimeo=0,vers=3,timeo=600,addr=10.0.0.2" look for the problem in the log file: cat /var/log/messages | grep mount  mount to NFS server '10.0.0.2' failed: timed out, retrying Solution: In most of the cases, you have a problem with your iptables in the destination server login as root to dest server (10.0.0.2) in my case and type this command: iptables --flush  the go back to your origin server to try remount the problematic NFS file system of course this is in case nfs server was installed and functioning properly. Good luck.

ora-65035 while create pluggable database from another one

or : ORA-21000: error number argument to raise_application_error of -65035 is out of range Cause: this error caused because of an unrecoverable transaction in the source DB. Solution: 1. either stop and start your pluggable source DB 2. identify the open transaction and kill it if you can. use this query to do so: select * from v$transaction t,v$session  s where t.ses_addr = s.saddr;
