My apologies for the tardiness in responding here ... we've had several
overlapping issues that have been demanding the attention of our open
source engineers and our legal team.
I would like to make the following proposal:
1. We bundle all of the source for the dbms PMDAs into one package
to be known as "DBMS Add-ons for Performance Co-Pilot". This would
include PMDA implementations for (old) verions of Oracle, Sybase,
Informix.
The name issue is important, because Performance Co-Pilot is a
trademark of SGI, and we have to take certain actions to protect
that trademark, and one of them is to ensure that there is no
confusion between the _real_ PCP, and something that "works with PCP".
Similarly adding Oracle, Informix and Sybase to the title will only
risk incuring the wrath of a different bunch of lawyers.
2. We negotiate and select someone to act as the gatekeeper for this
source.
SGI is not planning to maintain any down-stream responsibility for
this code, so in particular we do not want to deal with bug reports
or patches.
We are willing to add a pointer to it from the PCP project
page on oss.sgi.com.
3. We will make the source in 1. available to the person(s) selected in
2. under the standard GPL.
Thereafter, you can do with it as you please, subject to the terms and
conditions of the GPL.
Is this acceptable?
Could I ask for volunteers as per 2. above?
