Value Constraints

|
Low Memory GCThreshold
|
The threshold level (0-99 percent) at which this server logs low memory conditions and changes the server health state to "Warning." By default, the server logs a low memory warning in the log file and changes the server health state to Warning after the average free memory reaches 5 percent of the initial free memory measured at the server's boot time.
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 amount of time (in seconds) that defines the interval over which this server determines average free memory values. By default, the server obtains an average free memory value every 3600 seconds.
This interval is not used when the server runs under the JRockit VM. Instead, memory samples are collected immediately after the JRockit VM performs scheduled garbage collection. Sampling memory after a garbage collection provides a more accurate average of free memory.
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:
|
|
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:
|
|
Socket Buffer Size As Chunk Size
|
Specifies whether the server's buffer size for sending or receiving data through a raw socket should be set to 4KB. Otherwise, the server does not impose a limit to the buffer size and defers to the operating system. This option is useful only on some operating systems for improving performance. It should be disabled in most environments.
MBean: weblogic.management.
configuration.KernelMBean
Attribute: SocketBufferSizeToChunkSize
|
Default: false
Valid values:
