Command Options

Option Type Description Default Mandatory

Option	Type	Description	Default	Mandatory

--target

Instance or cluster name

Specifies the targeted instance or cluster.

server

Example

asadmin> restart-hazelcast --target instance-name
instance-name:
Hazelcast Restarted

If multiple Payara Server instances are targeted for restart of the underlying Hazelcast instance then data loss can occur in the Data Grid

`list-cache-keys`

Since Payara Server 4.1.1.154

Aim: Lists all keys in a cache. If no cache is specified, keys from all caches will be returned.
Usage: asadmin> list-cache-keys

Command Options

Option	Type	Description	Default	Mandatory

Option

Type

Description

Default

Mandatory

name

String

Name of the cache to query

`list-caches`

Since Payara Server 4.1.1.154

Aim: Lists the Hazelcast distributed caches in the cluster
Usage: asadmin list-caches

`clear-cache`

Since Payara Server 4.1.1.154

Aim: Clears a Hazelcast or JCache IMap
Usage: asadmin> clear-cache <cacheName>

Use of this commands removes all data from a cache and therefore can result in unexpected behaviour if a system cache is cleared. Clearing a cache containing web session data will result in all users losing their sessions.

`create-hazelcast-instance`

Since Payara Server 4.1.2.172

This is deprecated in 5.181 onwards as by default all instances are created as part of the Domain Data Grid

Usage: asadmin> create-hazelcast-instance new-instance
Aim: Creates a new Payara Server instance with Hazelcast and the persistence types.

Command Options
