Hello all,
I'm trying to install in a multi node environment now, for that I tried to install vision database. I followed the oracle documentation inside the disk. The doc stated that we must install the db tier first so I did. The problem occured in post installation check. It said it cannot connect to the database but I could continue to the next step. Not know what to do I tried to install the application tier and in the pre-installation check it said it cannot connect to the database too and still I could continue the installation process. I tried to start the database by running the addbctl.sh and addlnctl.sh script in the dbtier (like I used to do in a single node installation) then I tried to repeat the pre-installation check in the apps tier but still the same error.
What's wrong? Can we install vision database in a multi node environment or we must do a fresh install to try multi node environment? Please help. Thanks.
How to Install in multi node environment?
1- Check if you are able to ping the db machine from apps machine with fully qualified domain name,
db.abc.com
apps.abc.com
on both machine check connectivity with this if not able to ping then you need to resolve by adding entries in the hosts file. The hosts entries are documented in the installation documents. thanks

Hi all,
I tried to search first in this forum about my question and couldn't find it (hope I didn't miss anything in my search) so I raised this question.
I want to ask (again
) something about multinode installation. In node information when we do multinode installation there's a check box of Enable a shared file system for this instance.
1. Is it right if I assumed that we must check that box if we want to install apps tier in more than one server so that if we only want to install apps tier in only one server then we don't need to check that option? Or we better check it even no matter how many server we installed apps tier into?
2. If I still uncheck that option will there be any problem such as in backup & restore, clone, testing activity, etc?
3. When we created user for each db tier and apps tier, what will be better, create the same user for both tiers or differentiate user for each db tier and apps tier? I'm thinking of using same user for both tiers to avoid privilege problem later on.
4. Can we start preclone and adcfgclone process in db tier and apps tier paralel in multinode environment or still start clone process in db tier first then apps tier? (I assumed that we may not started preclone and adcfgclone process paralel but we may for the copy process).
5. Assume that we want to clone from 2 node machines (apps and db) to another 2 node machines (apps and db), do we need to copy admin, portal, rgf and temp folder from each tier to each target machine or we just omit that because in single node clone we just omit it? How about if the case is cloning from multinode to single node?
Thanks.

stupid me,
no.5 question occur because I installed concurrent processing server in db tier instead of apps tier. when I installed only db server in db tier there are only db and data folder in db tier. so then I assume clone multi node would be the same as single node process except for the location, right?
