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

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;
