Setting a Local Configuration Parameter

To change a local configuration parameter across multiple segments, update the parameter in the postgresql.conf file of each targeted segment, both primary and mirror. Use the gpconfig utility to set a parameter in all Greenplum postgresql.conf files. For example:

  1. $ gpconfig -c gp_vmem_protect_limit -v 4096

Restart Greenplum Database to make the configuration changes effective:

  1. $ gpstop -r
