RE: oracle_home

I have come to use my own version of oraenv; oraenvset as a replacement. oraenv has a spot for customizations, but then you have to be careful with root.sh. All my scripts call it, and I never have to worry about whether the sysadmin replaces oraenv. As far as I'm concerned he can hit Y every time. Seems to make life a lot easier, and the latest is always available but not used.

So... I'll continue with supporting arguments since I like it so much :) -- not to mention the script is much more flexible as it will work using just the ORACLE_HOME, or indeed anything in oratab by adding lines using the same conventions for databases... ie OMS, AGENT, LISTENER_<X> and so forth. For instance a dbstopall or dbstartall scripts can be run by the sysadmin for patching that simply cycles through oratab and shuts down or starts up everything, (depending on Y/N in oratab or if the line is commented). It sets the environment for each line by calling oraenvset.

In this example, the configuration manager is considered for every home by default (I don't list CCR in oratab). But there is a parameter that can optionally skip it, (NOCCR). oraenvset has extra customizations for older databases as well -- such as exp/imp for oracle 9 still uses language variables. (Inside the script there are case statements etc that determine much of what is needed).

FYI That link points to AUDIT on my phone... I agree entirely.
<RANT> I really, really, wish though that by default oraenv got installed in /usr/bin OR that the script was configured by root.sh so that calling scripts from cron with ORAENV_ASK=NO just worked. I've lost track of the number of cronjobs I've seen that don't work when called from cron, but do interactively. root.sh does allow you to 'misspecify' the local binary directory of course.

And whilst I've got you all in the back of my cab, wouldn't it be great if Oracle came up with a common oraenv across products and version controlled it so you didn't need to decide whether to answer Y/N to replacing the oraenv and associated scripts </RANT> On Apr 5, 2013 6:21 PM, "Hans Forbrich" <fuzzy.graybeard_at_gmail.com> wrote:
