Alert logs for 100databases

Question

Hi Techies,
we have nearly 100 databases to administrate , as part of our job, need to look alert logs of all the databases.what would be the easiest way to find the last day alert log file( need to navigate the alert log file location of each database and tail -f <Filename 500> to find the alert logs. This process will take time to go thru alert logs of all of our databases.).
I Kindly requesting all you to give the valuable ideas and suggestions.
DB:Oracle 10g (10.2.0.3.0)
OS :Solaris /HP-UX
Count of databases are increasing every 3 months.
Thanks,

Hi Tippu/ALL
I am also working on the same type scripts , Where it would fetch the last days (yesterdays)entri from alert_SID.log file and grep -ORA error on that.
But the tricky part is to fetch only yesterdays entry.
For that i am using awk '/BEGIN/,/END/' <filename>
wher it will give you the yesterdays entry.
Take the variable say YESTERDAY and TODAY where it will be the Y'days and T'days date.
But what i am fecing is alert_SID.log has the enrty somethiing like Oct 30 <some time say 15:25:54> 2009
And if your Y'day variable value is something like Oct 29 2009 nad TODAYS is Oct 30 2009.
If you user Y'day=Oct 29 and T'day=Oct 30
then your job will be done....
but the bug is it will fetch the through out year record say if u r ahving 2005,06,07,08,09 entry.
and if you use Y'day=Oct 29 2009 and T'day=Oct 30 2009
it wont give the o/p , because there is a timestamp btn this and which is varaible.
If any way mean if we can skip this "Oct 30 <some time say 15:25:54> 2009" time stamp i.e. hour entry then we can get the girl.
Please input neede
