-Search for any process name with locator running , kill it

-Start gfsh client

  gfsh

-Add locator

start locator --name=locatorTest

Configure pdx serialization rule

configure pdx --auto-serializable-classes=com\.thetechiehouse\.blogspot\.services\.sampleapp\.vo\..* --read-serialized=true --disk-store
Start server:

start server --name=server1 --classpath=<absolutepath>sample-app-service.jar --server-port=40411

Create a replicated, persistent region:

create region --name=region1 --type=PARTITION_PERSISTENT

List regions:

list regions

To view specific about regions:
describe region --name= region1

List members of your cluster:
list members

-Start gemfire pulse monitoring tool:
start pulse

Issue debugging on Production :

Important commands:

-show missing-disk-storeslist members
