System Properties

The following properties are used by Payara Server to configure special behavior settings:

Option Value Type Description Accepted Values Default

Option	Value Type	Description	Accepted Values	Default
fish.payara.clientHttpsProtocol	String	Sets the TLS version to be used by the asadmin client. This is separate from the TLS version set for HTTPS communication on a listener.	TLSv1, TLSv1.1, TLSv1.2, TLSv1.3	TLSv1.2
fish.payara.classloading.delegate	Boolean	When set to false, libraries from applications, and \({Domain}_/lib will override the library in _\){Product-Root}/modules directory	true, false	true
fish.payara.shutdowngrace	Integer	After server shutdown is initiated the server waits this period of time to finish ongoing requests before terminating. Currently, new requests are still accepted during this grace period.	0 - Integer.MAX	0
fish.payara.permittedFormBasedAuthHttpMethods	String	A comma separated list of HTTP methods that are permitted to use for FORM based authentication (`j_security_check`). If not set all HTTP methods are permitted.	GET,HEAD,POST,PUT,DELETE,CONNECT,OPTIONS,TRACE,PATCH	null (undefined)
fish.payara.admin.command.jline.log.disable	Boolean	When set to true, JLine logging entries for invalid key bindings and other unwanted errors will be prevented - This is a property for the asadmin tool	true, false	false
fish.payara.SO_KEEPALIVE	String	Enables keep alive (`SO_KEEPALIVE`) on the sockets created by an IIOP listener. Can be set as a global system property, or as a property on a specific listener (with the latter taking precedence over the global setting if both are set). Replaces deprecated property `fish.payara.SOKeepAlive`.	true, false	false (undefined)
org.glassfish.grizzly.DEFAULT_MEMORY_MANAGER	String	If the JVM option `org.glassfish.grizzly.DEFAULT_MEMORY_MANAGER` is not present in the server/instance config, we will override the Grizzly default and use the HeapMemoryManager class. To override this behaviour (so to use a different memory manager), you must specify this JVM option in the server/instance config with your desired setting.	`org.glassfish.grizzly.memory.HeapMemoryManager`, `org.glassfish.grizzly.memory.PooledMemoryManager`, `org.glassfish.grizzly.memory.ByteBufferManager`	`org.glassfish.grizzly.memory.HeapMemoryManager`

fish.payara.clientHttpsProtocol

String

Sets the TLS version to be used by the asadmin client. This is separate from the TLS version set for HTTPS communication on a listener.

TLSv1, TLSv1.1, TLSv1.2, TLSv1.3

TLSv1.2

fish.payara.classloading.delegate

Boolean

When set to false, libraries from applications, and \({Domain}_/lib will override the library in _\){Product-Root}/modules directory

true, false

true

fish.payara.shutdowngrace

Integer

After server shutdown is initiated the server waits this period of time to finish ongoing requests before terminating. Currently, new requests are still accepted during this grace period.

0 - Integer.MAX

fish.payara.permittedFormBasedAuthHttpMethods

String

A comma separated list of HTTP methods that are permitted to use for FORM based authentication (j_security_check). If not set all HTTP methods are permitted.

GET,HEAD,POST,PUT,DELETE,CONNECT,OPTIONS,TRACE,PATCH

null (undefined)

fish.payara.admin.command.jline.log.disable

Boolean

When set to true, JLine logging entries for invalid key bindings and other unwanted errors will be prevented - This is a property for the asadmin tool

true, false

false

fish.payara.SO_KEEPALIVE

String

Enables keep alive (SO_KEEPALIVE) on the sockets created by an IIOP listener. Can be set as a global system property, or as a property on a specific listener (with the latter taking precedence over the global setting if both are set). Replaces deprecated property fish.payara.SOKeepAlive.

true, false

false (undefined)

org.glassfish.grizzly.DEFAULT_MEMORY_MANAGER

String

If the JVM option org.glassfish.grizzly.DEFAULT_MEMORY_MANAGER is not present in the server/instance config, we will override the Grizzly default and use the HeapMemoryManager class. To override this behaviour (so to use a different memory manager), you must specify this JVM option in the server/instance config with your desired setting.

org.glassfish.grizzly.memory.HeapMemoryManager, org.glassfish.grizzly.memory.PooledMemoryManager, org.glassfish.grizzly.memory.ByteBufferManager

org.glassfish.grizzly.memory.HeapMemoryManager
