The following is an example of a host error message that is seen when you issue a TYPE command for a file larger than 32 KB using NVRunCMD: * IP659 RUN SP=R2841, APPL=NVRUNCMD CMD TYPE D:\TEMP\JUNK\A.TXT - DSIGDS DSI296I RUN FAILED. INVALID DATA RECEIVED FROM R2841 When this occurs, none of the returned data is displayed on the host. CAUSE ===== The NVRunCMD service is only designed to return up to 32 KB of data for each command. If the command results in more than 32 KB of data being returned, none of the data is returned. The "Invalid Data Received" error message is returned instead. RESOLUTION ========== SNA Server 3.0 -------------- To resolve this problem, obtain the latest service pack for SNA Server version 3.0.
