On Solaris, it may happen that the FIONREAD ioctl function returns 0 even if the socket is not closed. So, we can ask to retry ioctl call several times when it returns 0. Set the ILS_IOCTL_RETRIES environment variable to set the number of retries.

Set the backlog of the listen socket.

When a network failure occurs during reception of a buffer, the ::recv socket operation may block without returning an error. A ::select() call has been added to the MvTCP library, before any call to ::recv, to work around this behavior. To enable this work-around, you have to set up the ILS_TCP_USE_RECV_TIMEOUT environment variable. The time out can be set using the ILS_TCP_RECV_TIMEOUT environment variable (ms). The default value is 30s. If the ::select() times out, a communication error is triggered.

The default behavior when such an error is detected is to close the corresponding connection. This behavior is controlled by the method IlsMvProcess::DisconnectOnComError() which is, by default, set to true.

This behavior can also be triggered by the function:

void SetIlsTcpUseRecvTimeout(IlsBoolean useRecvTimeout, IlsTime recvTimeout).

Set the recv time out when ILS_TCP_USE_RECV_TIMEOUT is set.

Used to ignore the SIGPIPE signal instead of trapping it. As this signal may be triggered by the system during network operation on UNIX® platform, Rogue Wave® Server traps it. In not well defined situation, this signal may still be fired without going through the signal handler defined by Rogue Wave Server and stop the process. This environment variable allows ignoring the signal instead of trapping it.

The MvTCP read routine is retrying receiving data when the ::recv system call has been interrupted by a signal. Set this environment variable to raise an exception instead.

The behavior of the main loop has changed: exceptions are no longer raised if an error occurs during execution of the select command on the MvTcp communication layer; instead, only a trace is generated. This behavior can be changed:

* You can restore the old behavior by setting the environment variable ILS_TCP_OLDRUNBEHAVIOR.

* You can change the default behavior yourself by setting the static variable IlsTcpMvProcess_RunHook. The specification of this variable is:

void (* IlsTcpMvProcess_RunHook)(IlsSocketException & e).

ILS_TCP_PACKET_SIZE

ILS_TCP_SEND_PACKET_SIZE

ILS_TCP_RECV_PACKET_SIZE

ILS_TCP_SEND_PACKET_SIZE is defining the size of the packets when sending on a socket and ILS_TCP_RECV_PACKET_SIZE, the size of the packets when receiving from a socket. If ILS_TCP_PACKET_SIZE is defined, it is used instead of these two values for both sending and receiving.

The following functions are also defined that allow to set these values by code:

 

* void SetIlsTcpSendPacketSize(unsigned int size)

* void SetIlsTcpRecvPacketSize(unsigned int size)

 

Note: The Microsoft recommended value for packets size sent into a socket is 4 Mo.

Socket errors occurring in tcpd don't stop the service. Set ILS_TCPD_EXIT_ON_ERROR if you want tcpd to stop when encountering errors.

In the main loop, no exceptions is raised if an error occurs during execution of the select command on the MvTcp communication layer; but only a trace is generated. This behavior can be changed:

Introduces a new memory allocator dedicated to storing a temporary data structure built when a dynamic view is opened. Sets the variable ILS_USE_MLK to revert to the previous behavior (allocating these data structure in the main Rogue Wave Server memory allocator).

Delays the resizing of an internal cache. This cache was resized (size*2) when a view was opened for the second time, it is now resized later. This variable fixes the extra space available before resizing occurs.
