Method Detail

getHeaderTableSize

int getHeaderTableSize()

The server's maximum size of the header compression table used to decode header blocks, in octets.

Returns:

The headerTableSize value

See Also:

setHeaderTableSize(int)

setHeaderTableSize

void setHeaderTableSize(int headerTableSize)

Sets the server's maximum size of the header compression table used to decode header blocks, in octets. It's used to inform the remote endpoint.

Parameters:

headerTableSize -

Default Value:

Http2ConfigMBean.DEFAULT_HEADER_TABLE_SIZE

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

getMaxConcurrentStreams

int getMaxConcurrentStreams()

The maximum number of concurrent streams that the server will allow. This limit is directional: it applies to the number of streams that the server permits the receiver to create.

Returns:

The maxConcurrentStreams value

See Also:

setMaxConcurrentStreams(int)

setMaxConcurrentStreams

void setMaxConcurrentStreams(int maxConcurrentStreams)

Sets the maximum number of concurrent streams that the server will allow. This limit is directional: it applies to the number of streams that the server permits the receiver to create.

Parameters:

maxConcurrentStreams -

Default Value:

Http2ConfigMBean.DEFAULT_MAX_CONCURRENT_STREAMS

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

getInitialWindowSize

int getInitialWindowSize()

The server's initial window size (in octets) for stream-level flow control. This setting affects the window size of all streams.

Returns:

The initialWindowSize value

See Also:

setInitialWindowSize(int)

setInitialWindowSize

void setInitialWindowSize(int initialWindowSize)

Sets the server's initial window size (in octets) for stream-level flow control. This setting affects the window size of all streams.

Parameters:

initialWindowSize -

Default Value:

Http2ConfigMBean.DEFAULT_INITIAL_WINDOW_SIZE

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

getMaxFrameSize

int getMaxFrameSize()

The size of the largest frame payload that the server is willing to receive, in octets.

Returns:

The maxFrameSize value

See Also:

setMaxFrameSize(int)

setMaxFrameSize

void setMaxFrameSize(int maxFrameSize)

Sets the size of the largest frame payload that the server is willing to receive, in octets.

Parameters:

maxFrameSize -

Default Value:

Http2ConfigMBean.DEFAULT_MAX_FRAME_SIZE

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

getMaxHeaderListSize

int getMaxHeaderListSize()

The maximum decoded size, in bytes, of an HTTP/2 request header block that WebLogic Server accepts. The default is 131072 bytes. The size is the sum of each field name and value, plus 32 bytes for each field. Initial request headers and request trailers are checked separately. If a client exceeds this limit, WebLogic Server rejects that HTTP/2 stream and keeps the connection available for other streams. WebLogic Server also advertises this limit to clients.

Returns:

the maximum decoded size, in bytes, accepted in one request header block

See Also:

setMaxHeaderListSize(int)

setMaxHeaderListSize

void setMaxHeaderListSize(int maxHeaderListSize)

Sets the maximum decoded size, in bytes, of an HTTP/2 request header block that WebLogic Server accepts. The default is 131072 bytes. The size is the sum of each field name and value, plus 32 bytes for each field. Initial request headers and request trailers are checked separately. If a client exceeds this limit, WebLogic Server rejects that HTTP/2 stream and keeps the connection available for other streams. WebLogic Server also advertises this limit to clients. Changes take effect on newly established HTTP/2 connections. The value must not be negative.

Parameters:

maxHeaderListSize - the maximum decoded size, in bytes, accepted in one request header block

Default Value:

Http2ConfigMBean.DEFAULT_MAX_HEADER_LIST_SIZE

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

Maximum Value:

java.lang.Integer.MAX_VALUE

getMaxHeaderCount

int getMaxHeaderCount()

The maximum number of decoded HTTP/2 header fields that the server accepts in one header field list. This is a local inbound protection and is not an HTTP/2 SETTINGS parameter. Pseudo-header fields, repeated fields, and each separately encoded Cookie field count toward the limit. Initial headers and trailers have independent limits on newly established connections.

Returns:

the maximum number of decoded fields in one header field list

See Also:

setMaxHeaderCount(int)

setMaxHeaderCount

void setMaxHeaderCount(int maxHeaderCount)

Sets the maximum number of decoded HTTP/2 header fields that the server accepts in one header field list. This is a local inbound protection and is not an HTTP/2 SETTINGS parameter. Pseudo-header fields, repeated fields, and each separately encoded Cookie field count toward the limit. Initial headers and trailers have independent limits on newly established HTTP/2 connections. Increasing this value increases the amount of memory that a peer can cause the server to use for headers.

Parameters:

maxHeaderCount - the maximum number of decoded fields in one header field list

See Also:

getMaxHeaderCount()

Default Value:

Http2ConfigMBean.DEFAULT_MAX_HEADER_COUNT

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

Maximum Value:

32767

Minimum Value:

1

getMaxStreamResets

int getMaxStreamResets()

Gets the maximum number of stream resets(RST_STREAM frames) allowed per connection.

Returns:

the number of stream resets(RST_STREAM frames) allowed per connection

See Also:

setMaxStreamResets(int)

setMaxStreamResets

void setMaxStreamResets(int maxStreamResets)

Sets the maximum number of stream resets(RST_STREAM frames) allowed per connection.

Parameters:

maxStreamResets - the number of stream resets(RST_STREAM frames)

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

getFrameCountLimitResetInterval

int getFrameCountLimitResetInterval()

Gets the frame count limit reset interval

Returns:

the frame count limit reset interval in seconds

See Also:

setFrameCountLimitResetInterval(int)

Default Value:

60

setFrameCountLimitResetInterval

void setFrameCountLimitResetInterval(int interval)

Sets the frame count limit reset interval

Parameters:

interval - the frame count limit reset interval value in seconds

getContinuationFramesLimit

int getContinuationFramesLimit()

Gets the number of CONTINUATION frames allowed per stream.

Returns:

the number of CONTINUATION frames

setContinuationFramesLimit

void setContinuationFramesLimit(int continuationFramesLimit)

Sets the number of CONTINUATION frames allowed per stream.

Parameters:

continuationFramesLimit - the new limit

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.
