recurring run of sh script in crontab
Hello gurus.
I have a problem: my crontab -e is looks like this:
ORACLE_SID=bla-bla
* 21 * * * (sqlplus hotback/hotback @/oracle/backups/bla-bla/scripts/hotback/daily_hotback.sql)
0 19 * * * /oracle/backups/dev10g/scripts/exports/daily_exports.sh
0 1 * * * /oracle/backups/dev10g/scripts/exports/export_compress.sh
All was great untill May 4, when this script began to run every minute during the hour (21:00). Here is a log from /var/log/cron:
May 4 21:00:01 localhost crond[7267]: (oracle) CMD ((sqlplus hotback/hotback @/oracle/backups/bla-bla/scripts/hotback/daily_hotback.sql))
May 4 21:01:01 localhost crond[7278]: (oracle) CMD ((sqlplus hotback/hotback @/oracle/backups/bla-bla/scripts/hotback/daily_hotback.sql))
May 4 21:01:01 localhost crond[7280]: (root) CMD (run-parts /etc/cron.hourly)
May 4 21:02:01 localhost crond[7284]: (oracle) CMD ((sqlplus hotback/hotback @/oracle/backups/bla-bla/scripts/hotback/daily_hotback.sql))
May 4 21:03:01 localhost crond[7291]: (oracle) CMD ((sqlplus hotback/hotback @/oracle/backups/bla-bla/scripts/hotback/daily_hotback.sql))
and so on, all the way during the 9PM and at 22:00 it stops.
I'm a newbie in Unix and really don't understand, why this happens.
BTW, we have 4 boxes with the same job in cron, all of them look like:
0 21 * * * (sqlplus hotback/hotback @/bla-bla/hotback/daily_hotback.sql) (I mean, the first is "0" instead of * (asterics). Could it be the reason?)
As you may be see, this script makes hot backups from datafiles on DBs, and due to this recurring scripts, we have 60 processes, that try to make bakup. At the end, a system hungs, and hotbackups are not finished.
If you have any ideas, please, help me! I would really appreciate that!
Thank you forehand,
M.

Config::Model::DumpAsData(3pm) User Contributed Perl Documentation Config::Model::DumpAsData(3pm)
NAME
Config::Model::DumpAsData - Dump configuration content as a perl data structure
VERSION
version 2.021
SYNOPSIS
use Config::Model ;
use Log::Log4perl qw(:easy) ;
use Data::Dumper ;
Log::Log4perl->easy_init($WARN);
# define configuration tree object
my $model = Config::Model->new ;
$model ->create_config_class (
name => "MyClass",
element => [
[qw/foo bar/] => {
type => 'leaf',
value_type => 'string'
},
baz => {
type => 'hash',
index_type => 'string' ,
cargo => {
type => 'leaf',
value_type => 'string',
},
},
],
) ;
my $inst = $model->instance(root_class_name => 'MyClass' );
my $root = $inst->config_root ;
# put some data in config tree the hard way
$root->fetch_element('foo')->store('yada') ;
$root->fetch_element('bar')->store('bla bla') ;

# put more data the easy way

# $VAR1 = {
# 'bar' => 'bla bla',
# 'baz' => {
# 'en' => 'hello',
# 'fr' => 'bonjour',
# 'hr' => 'dobar dan'
# },
# 'foo' => 'yada'
# };
DESCRIPTION
This module is used directly by Config::Model::Node to dump the content of a configuration tree in perl data structure.
The perl data structure is a hash of hash. Only CheckList content will be stored in an array ref.
Note that undefined values are skipped for list element. I.e. if a list element contains "('a',undef,'b')", the data structure will contain
'a','b'.
CONSTRUCTOR
new ( )
No parameter. The constructor should be used only by Config::Model::Node.
Methods
dump_as_data(...)
Return a perl data structure
Parameters are:
node
Reference to a Config::Model::Node object. Mandatory
full_dump
Also dump default values in the data structure. Useful if the dumped configuration data will be used by the application. (default is
yes)
skip_auto_write
Skip node that have a "perl write" capability in their model. See Config::Model::AutoRead.
auto_vivify
Scan and create data for nodes elements even if no actual data was stored in them. This may be useful to trap missing mandatory values.
ordered_hash_as_list
By default, ordered hash (i.e. the order of the keys are important) are dumped as Perl list. This is the faster way to dump such hashed
while keeping the key order. But it's the less readable way.
When this parameter is 1 (default), the ordered hash is dumped as a list:
[ A => 'foo', B => 'bar', C => 'baz' ]
When this parameter is set as 0, the ordered hash is dumped with a special key that specifies the order of keys. E.g.:
{ __order => [ 'A', 'B', 'C' ] ,
B => 'bar', A => 'foo', C => 'baz'
}
Methods
dump_annotations_as_pod(...)
Return a string formatted in pod (See perlpod) with the annotations.
Parameters are:
node
Reference to a Config::Model::Node object. Mandatory
experience
master, advanced or beginner
check_list
Yes, no or skip
