[Hardhats-members] Setting up HL LOGICAL LINKs problem - No response

[Usha]

Hi all   We want to have connection between two VistA systems, so that they can exchange patient data between themselves. According to the manuals, the first step is to establish a connection between them using the HL7 links. The specification of the two systems is   Server A (TCP server) 1. IP address is 192.168.1.31 2. Cache on NT 3. Following is the entry added to HL LOGICAL LINK file   NUMBER: 210                                                        NODE: ZVISTA   INSTITUTION: ZZ.EHR OFFICE                         LLP TYPE: TCP   DEVICE TYPE: Multi-threaded Server              STATE: Reading   TIME STOPPED: DEC 06, [EMAIL PROTECTED]:22:51   SHUTDOWN LLP ?: NO   QUEUE SIZE: 100                                               ACK TIMEOUT: 600   TCP/IP ADDRESS: 192.168.1.31                     TCP/IP PORT: 5000   TCP/IP SERVICE TYPE: MULTI LISTENER     PERSISTENT: YES   STARTUP NODE: EHR:CACHEWEB               SAY HELO: YES     Server B (TCP client) 1. IP address is 192.168.1.201 2. GT.M on Linux 3. Following is the entry added to HL LOGICAL LINK file   NUMBER: 194                                                         NODE: ETL2   INSTITUTION: ZZ.EHR OFFICE                           LLP TYPE: TCP   DEVICE TYPE: Persistent Client                        STATE: Idle   AUTOSTART: Enabled                                         TIME STARTED: DEC 06, [EMAIL PROTECTED]:47:56   TIME STOPPED: DEC 06, [EMAIL PROTECTED]:47:56     SHUTDOWN LLP ?: NO   QUEUE SIZE: 100                                                 ACK TIMEOUT: 600   TCP/IP ADDRESS: 192.168.1.31                       TCP/IP PORT: 5000   TCP/IP SERVICE TYPE: CLIENT (SENDER)    PERSISTENT: NO   STARTUP NODE: ROU:local                                SAY HELO: YES   On running PING (TCP only) option from Server B, the message displayed is "No response". And the STATE of ZVISTA link on Server A is READING.   The HL7 Site Manager and Developer Manual says "No response" means "VISTA HL7 was able to get a connection, but failed to get a response. In this case, a listener is running on the target system, but something else is wrong: the listener is a foreign listener (e.g., the RPC Broker), or the link entry for the listener on the receiving system is not defined correctly."   Can someone help detect the possible problem?   Regards Usha Make sure YOUR emails don't get lost!
