   Some systems have trouble with long identifiers. The SID gets various prefixes and postfixes, and if you have a long SID this can cause problems for systems that have restrictions on identifiers. An example is the server processes. This can cause issues on client platforms that are networked to your server. That is why Oracle has recommended keeping the SID short. You don't say what platform you are on, so I don't know if it applies to your system. Safe bet that 6 isn't likely to cause severe problems.

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
