There are maintenance reasons for some of these requirements- for example the listener can only ever be on the same box as the database, but I might want to take the listener down but keep the database up. I realize it's an odd requirement. > I hadn't read that part so closely when I said "shouldn't be too hard" > and indeed that is hard for us to express. > In Pacemaker, either A needs B or it doesn't. Fair enough. I'm not the database guy so I've been asked to replicate this VCS configuration as closely as possible. At the same time- I want to understand pacemaker as well as I can. I appreciate your feedback. > Other than that, you seem to want: > > order OraInstance1 OraBin1 > order OraInstance1 OraData1 > > order OraListener1 OraBin1 > order OraListener1 OraData1 > order OraListener1 OraIP1 > > Do OraInstance1/OraListener1 need to live on the same host as > OraBin1/OraData1 ? > If so, you can get the behaviour you're after by adding something like: > > colocate OraInstance1 OraBin1 > colocate OraListener1 OraBin1 > colocate OraBin1 OraData1 > > So OraInstance1 and OraListener1 can go up/down individually but > always on the same host as OraBin1/OraData1. > Also, if OraBin1 or OraData1 go down they'll take OraInstance1 and > OraListener1 with them. > > Is that close? That is exactly what I am trying to accomplish. I started to think along those lines after your previous email (and doing a little more reading) but I hadn't gotten there. The only part I'm not clear on is - doesn't: > colocate OraListener1 OraBin1 imply: > order OraListener1 OraBin1 ? Or to put it another way- I'm not sure I understand the difference between: colocate OraListener1 OraBin1 and: colocate (OraListener1 OraBin1) order OraListener1 OraBin1 ? Regardless of the answer- I should be able to get the config set up the way I need.
