Enable Native IO

Whether or not native I/O is enabled for the server.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: NativeIOEnabled

Default: true

Valid values:

• true

• false

Configurable: yes

Socket Readers

The percentage (1-99) of execute threads from the default queue hat may be used as socket readers.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: ThreadPoolPercentSocketReaders

Minimum: 1

Maximum: 99

Default: 33

Configurable: yes

Dynamic: yes

Maximum Open Sockets

The maximum number of open sockets allowed in server at a given point of time. When max threshold is reached, server stops accepting any more new requests until no of sockets drops below threshold.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: MaxOpenSockCount

Minimum: -1

Maximum: 2147483647

Default: -1

Configurable: yes

Dynamic: yes

Accept Backlog

Allowed backlog of new TCP connection requests for both the plaintext and SSL port. Setting the backlog to 0 may prevent accepting any incoming connection on some of the OS.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: AcceptBacklog

Minimum: 0

Default: 50

Dynamic: yes

Login Timeout

The login timeout for the server's plain-text (non-SSL) port, in milliseconds. This is the maximum amount of time allowed for a new connection to establish. A value of 0 indicates there is no maximum. The value must be equal to or greater than 0.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: LoginTimeoutMillis

Units: milliseconds

Minimum: 0

Maximum: 100000

Default: 5000

Dynamic: yes

Reverse DNS Allowed

Returns whether or not the kernel is allowed to perform reverse DNS lookups.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: ReverseDNSAllowed

Default: false

Valid values:

• true

• false

Configurable: yes

Dynamic: yes

Low Memory GCThreshold

The threshold level (a percentage value) at which we will try to garbage collect once the granularity reporting level has been met.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: LowMemoryGCThreshold

Minimum: 0

Maximum: 99

Default: 5

Configurable: yes

Low Memory Granularity Level

The granularity level used in reporting LowMemory information.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: LowMemoryGranularityLevel

Minimum: 1

Maximum: 100

Default: 5

Configurable: yes

Low Memory Sample Size

The total sample size used for LowMemoryTimeInterval. By default '10' samples are taken at each LowMemoryTimeInterval.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: LowMemorySampleSize

Minimum: 1

Maximum: 2147483647

Default: 10

Configurable: yes

Low Memory Time Interval

The time interval. So every configured 'time', one sample will be taken up to the LowMemorySampleSize and then repeated.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: LowMemoryTimeInterval

Units: seconds

Minimum: 300

Maximum: 2147483647

Default: 3600

Configurable: yes

Managed Server Independence Enabled

Indicates whether Managed Server Independence is enabled for this server. With Managed Server Independence enabled, you can start a Managed Server even if the Administration Server is unavailable. In such a case, the Managed Server retrieves its configuration by reading a configuration file and other files directly.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: ManagedServerIndependenceEnabled

Default: true

Valid values:

• true

• false

MSI File Replication Enabled

Indicates whether the replication of configuration files is enabled for a Managed Server. With file replication enabled, the Administration Server copies its configuration file and SerializedSystemIni.dat into the Managed Server's root directory every 5 minutes. This option does not replicate a boot identity file.

Regardless of the name of the configuration file that you used to start the Administration Server, the replicated file is always named msi-config.xml. For example, if you specified -Dweblogic.ConfigFile=MyConfig.xml when you started the Administration Server, if you have enabled file replication, the Administration Server copies MyConfig.xml and names the copy msi-config.xml.

Depending on your backup schemes and the frequency with which you update your domain's configuration, this option might not be worth the performance cost of copying potentially large files across a network.

MBean: weblogic.management.
configuration.ServerMBean

Attribute: MSIFileReplicationEnabled

Default: false

Valid values:

• true

• false
