Error description
It is not possible to customise the receive buffer size for TLS sockets created by the Integration Server. For use cases that involve receiving large amount of BLOB data over TLS, for example as the response to a HTTPRequest Node request this can lead to unnecessary performance degradation. This fix introduces the environment variable MQSI_MBSSLSOCKET_RECV_BUFFER_SIZE, when set to an integer value this allows the user to determine the receive buffer size used in bytes.

Problem summary
**************************************************************** USERS AFFECTED: All users of App Connect Enterprise version 11 or 12 making outbound TLS conenctions, for example by using the HTTP or SOAPRequest Nodes of the TCPIP Client nodes. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: <span style="background-color:rgb(255, 255, 255)">It is not possible to customise the receive buffer size for TLS sockets created by the Integration Server.

Problem conclusion
<span style="background-color:rgb(255, 255, 255)">This fix introduces the tcpTLSBufferSize property to the SocketConnectionManager resource manager in the server.conf.yaml file. When set to a positive integer value this allows the user to control the size of the receive buffer used when making outbound TLS socket connection. For example</span> SocketConnection Manager: tcpTLSBufferSize 1000000 # Set the receive buffer size to use for TLS operations <span style="background-color:rgb(255, 255, 255)"> This fix also introduces the environment variable MQSI_MBSSLSOCKET_RECV_BUFFER_SIZE, when set to an integer value this allows the user to determine the receive buffer size used in bytes. </span> --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v11.0 11.0.0.17 v12.0 12.0.4.0 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
