Interesting RMAN induced "hang" behavior

2009-11-27T16:59:52Z

So I recently ran down a really weird problem we were having on one of
our production 10.2.0.4 servers.
To make a long story short, recently during the RMAN backup window,
the database would go into a "locked" state and all transactions would
pause. Lock durations ranged from a few seconds (which nobody

Thanks for the feedback guys, that's exactly what I was looking for.
Oracle 10.2.0.4, OS is Red-Hat ES 5 (64 bit). Controller does support
multiple paths, and we'll be running the database with asynchronous IO
enabled (although I'm not thinking that'll impact disk layout, but
I've been wrong before).

SYS login possible in sqlplus, but not in Enterprise Manager

Hi everybody!
After restoring a RMAN backup to another machine (database and applikation
running fine with no probs) I'm experiencing the following problem:
I can logon using sqlplus and login SYS or SYSTEM. Not problems here, but I

Just noticed you're using a GNU system, so with bash/GNU find you can
use the following syntax:
_path="/apps12i"
read -p'enter filename: '
_found="$(
find "$_path" -type f -name "$REPLY" -printf 'found: %p\n'
)"
[[ $_found ]] &&
printf '%s\n' "$_found" ||
printf 'cannot find %s under %s\n' "$REPLY" "$_path"

Try changing the script like this:
_path="/apps12i"
printf 'enter filename: '
read
_found="$(
find "$_path" -type f -name "$REPLY" -exec printf 'found: %s\n' {} \;
)"
[ "$_found" ] &&
printf '%s\n' "$_found" ||
printf 'cannot find %s under %s\n' "$REPLY" "$_path"

Re: Hash cluster, parameter SIZE

2009-11-27T08:43:25Z

Thanks, i got it now.
I misreaded this:
If SIZE is larger than the data block size, then the database uses the
operating system block size, reserving at least one data block for
each cluster or hash value.
I haven't mentioned, that the size of my cluster was +/- 2000003 *
8KB. My os_block_size is set to 1K, db_block_size is set to 8K.

Hi all,
My scripts looks like this .. when i execute this script its says file
does not exist even though file is present physically and if the file
does not present in the file system then the output is null.

echo " enter file "
read name
for i in `find /apps12i -type f -name $name -printf %f `

Hash cluster, parameter SIZE

2009-11-26T09:32:15Z

Hi everyone.
I have a table with transactions of customers. There are about 20
transactions per month for a customer, I need to store history of 24
months. There is about 1 500 000 customers. Average length of row is
300 bytes.
The only select statements on this table would be count of
transactions, balance of transactions, etc., etc of one customer.
