Starting from SDD 1.5.1.0 release we are providing a way to dynamically enable and disable the port binding for sddsrv. We are shipping sddsrv.conf file with the package which contains parameters to enable the port binding. By default sddsrv will not bind to any tcpip port. Sddsrv.conf file contains following parameters: 1. enableport - This parameter allows user to enable or disable sddsrv to bind to tcpip port. Default value of this parameter is set to false. User can set this parameter to true if he wants to enable the tcpip interface of sddsrv. 2. loopbackbind - If user sets enableport parameter to true, then this parameter specifies if sddsrv will listen to any Internet address or the loopback (127.0.01) address. To enable sddsrv to listen to any Internet address, this parameter must be set to false. If enableport parameter is set to false, this parameter will not have any effect. 3. portnumber - This parameter specifies the portnumber on which sddsrv will bind to. Default value of this parameter is 20001. User can modify this parameter to change the portnumber. If enableport parameter is set to true, then this parameter must be set to valid port number on which sddsrv can bind upon. Please use the port number which is not used by any other application. User can modify any of this parameters anytime while sddsrv is running and thus can enable or disable tcpip interface dynamically. Also since sddsrv tcpip interface by default is disabled, SDD provides a way to get the sddsrv trace. You will find sddsrv.log and sddsrv_bak.log files in \%windir%\system32\ directory. These are wrapped around files and each are 4 MB in size at MAX.User should ensure there is at least 8 megabyte disk space available on system driver(the drive where Windows is installed). 3.3.2 Enhance SDD first time data capture (ref CMVC 59562) SDD driver code and sddsrv code have been changed to collect SDD trace periodically and write the data to the system local hard drive. Sddsrv will maintain two 4MB trace files on the hard drive, namely sdd.log and sdd_bak.log. These trace files are placed under \%windir%\system32\. Plus the space requirement for sddsrv, User should ensure there is at least 16 megabyte disk space available on system driver(the drive where Windows is installed). ================================================================================= 3.4 Known Issues None ================================================================================= 3.5 Known issues and workaround details None. --------------------------------------------------------------------------------- 4.0 User license agreement for IBM device drivers NOTICE: PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE PROGRAM AND DOCUMENTATION.
