Reading some documentation 63 is the max length for windows names, may have some problems with DNS systems 15 is recommended for backward compatibility with Win NT All of our servers use 15 chars or less, some DOD standard thingy On Oracle 8.1.7.4.1, the desc for v$instance length is 64 Our 15 char ones show perfectly well Georgette P Cornio ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Howard Latham Sent: Friday, April 03, 2009 10:36 To: michael.arm@xxxxxxx Cc: oracle-l-freelists; oracle-db-l Subject: Re: windows host name length We have one called exchange-2009 I think that's our longest 2009/4/3 Arm, Mike (IS) <michael.arm@xxxxxxx> I just checked my windows box running Windows Server 2003/Oracle 10.2.0.2.0 and the 12 character name shows up just fine in v$instance. All my redhat boxes have 6 or 7 character names.

The name would be 12 characters in length. Are there any limitations on windows for the length of a server name?
