Hello everyone,
I need help with the entry in this file.
Current system has it set up for this and it works, but i am wondering what each means.

# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
default:/oracle/product/8.0.5:N
dev009:/oracle/product/8.0.5:Y:oracle dev:DEV009
*:/oracle/product/8.0.5:N
#

Questions:
mulitple entries not allowed, why does it look like there are three entries.

What does the default: mean?

What does the * mean in front of the last one?

Why does one have dev009 in from of it and :oracle dev:DEV009 at the end of it.

syntax in the book shows only one entry
ORACLE_SID:ORACLE_HOME: (Y|N)

Which one is correct or which line do you think I am using?

Thanks
Kathy
