ICVTSD
The ICVTSD system initialization parameter specifies the terminal scan delay value.
- ICVTSD={0|number}
- The terminal scan delay facility was used in earlier releases to limit how quickly CICS® dealt with some types of terminal output requests made by applications, in order to spread the overhead for dealing with the requests. The range is 0 through 5000 milliseconds. Specifying a nonzero value was sometimes appropriate where the CICS system used non-SNA networks. However, with SNA and IPIC networks, setting ICVTSD to 0 is appropriate to provide a better response time and best virtual storage usage.
