My std. also, 4 chars for db with last char denoting db use (Production, Test, Development, Training, etc.). I started on VMS Oracle 6, seemed to be the case back then, still hold to it. I used to have dns aliases for db names, VMS node name limit was 6 chars. For example:
Payroll DB Names —------------------- payp=Prod payt=Test payd=Development ... Payroll DB Server Names —--------------------------- paypdb=Prod DB Server DNS Alias paytdb=Test DB Server DNS Alias payddb=Development DB Server DNS Alias ... This worked well before oracle names. Move a db, make a DNS change, done. Old habits are hard to break, never had a need to :) fwiw, Gene >>> [EMAIL PROTECTED] 07/30/02 04:22PM >>> We have SIDs 9 chars long! Ron SMith -----Original Message----- Sent: Tuesday, July 30, 2002 3:08 PM To: Multiple recipients of list ORACLE-L Hi, What is the reason behind DB_Name/SID usually 4 chars length only. I have a customer who is asking us to create instance/db with 6 chars length. We usually keep instance name and db_name parameters same in .ora file. Can someone please explain the reason behind db_name 4 chars only. Is it a common practice to keep SID/db_name/instance name parameters same (for example PBDS). thanks Srinivas __________________________________________________ Do You Yahoo!? Yahoo!
