Narrative:
I was working radar position 15. My adjacent sector 6, called to inform me of traffic requesting IFR. Sector 6 '/oked' (logic override function). The departure message and initiated a data block only handoff. I accepted the handoff and subsequently issued IFR clearance. The 'dm' message that sector 6 initiated caused an 'unsuccessful message' to display on my vdm (video display monitor) which I did not catch. The aircraft traversed my sector normally, but when a handoff was initiated to ZDV (denver), it failed. I was very busy with other duties in the sector and didn't notice the failed 'flash.' I reinitiated the handoff, only to have it fail again. (The second time always works!) I noticed the data block not flashing anymore, so I thought, and issued a frequency change to the aircraft. A mins or so later, I received a call from ZDV, 'who is this guy?' no flight plan information had passed to ZDV. Fortunately, I was able to initiate a manual handoff and pass flight plan information prior to the aircraft exiting my airspace. No foul! However, I was removed from duty because of a 'performance issue.' failure to recognize an unsuccessful flight plan!? The failure was a result of ZDV computer not recognizing the obscure departure airport in ZLC airspace. This lack of computer input/database could have caused a serious problem. But fortunately, I was able to quickly cover steps and avoid that situation. With dsr on-line and the fact that the denver computers have ample storage capacity, there should be no excuses for any airport not being stored in any database! 3-LETTER identifiers do not consume any, or very little, computer memory. This should have never happened!

Title: ZDV CTLR ALERTS ZLC CTLR OF UNCOORD COM HDOF XFER OF ENRTE GV.
Narrative: I WAS WORKING RADAR POS 15. MY ADJACENT SECTOR 6, CALLED TO INFORM ME OF TFC REQUESTING IFR. SECTOR 6 '/OKED' (LOGIC OVERRIDE FUNCTION). THE DEP MESSAGE AND INITIATED A DATA BLOCK ONLY HDOF. I ACCEPTED THE HDOF AND SUBSEQUENTLY ISSUED IFR CLRNC. THE 'DM' MESSAGE THAT SECTOR 6 INITIATED CAUSED AN 'UNSUCCESSFUL MESSAGE' TO DISPLAY ON MY VDM (VIDEO DISPLAY MONITOR) WHICH I DID NOT CATCH. THE ACFT TRAVERSED MY SECTOR NORMALLY, BUT WHEN A HDOF WAS INITIATED TO ZDV (DENVER), IT FAILED. I WAS VERY BUSY WITH OTHER DUTIES IN THE SECTOR AND DIDN'T NOTICE THE FAILED 'FLASH.' I REINITIATED THE HDOF, ONLY TO HAVE IT FAIL AGAIN. (THE SECOND TIME ALWAYS WORKS!) I NOTICED THE DATA BLOCK NOT FLASHING ANYMORE, SO I THOUGHT, AND ISSUED A FREQ CHANGE TO THE ACFT. A MINS OR SO LATER, I RECEIVED A CALL FROM ZDV, 'WHO IS THIS GUY?' NO FLT PLAN INFO HAD PASSED TO ZDV. FORTUNATELY, I WAS ABLE TO INITIATE A MANUAL HDOF AND PASS FLT PLAN INFO PRIOR TO THE ACFT EXITING MY AIRSPACE. NO FOUL! HOWEVER, I WAS REMOVED FROM DUTY BECAUSE OF A 'PERFORMANCE ISSUE.' FAILURE TO RECOGNIZE AN UNSUCCESSFUL FLT PLAN!? THE FAILURE WAS A RESULT OF ZDV COMPUTER NOT RECOGNIZING THE OBSCURE DEP ARPT IN ZLC AIRSPACE. THIS LACK OF COMPUTER INPUT/DATABASE COULD HAVE CAUSED A SERIOUS PROB. BUT FORTUNATELY, I WAS ABLE TO QUICKLY COVER STEPS AND AVOID THAT SIT. WITH DSR ON-LINE AND THE FACT THAT THE DENVER COMPUTERS HAVE AMPLE STORAGE CAPACITY, THERE SHOULD BE NO EXCUSES FOR ANY ARPT NOT BEING STORED IN ANY DATABASE! 3-LETTER IDENTIFIERS DO NOT CONSUME ANY, OR VERY LITTLE, COMPUTER MEMORY. THIS SHOULD HAVE NEVER HAPPENED!
