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 LightDB-A postgresql.conf files. For example:

$ gpconfig -c gp_vmem_protect_limit -v 4096

Restart LightDB-A Database to make the configuration changes effective:

$ gpstop -r
