check_oracle_rman_b

本人不是Oracle DBA，不懂Oracle，告警了運維又不管，說是DBA的活，反正在他們眼裏無論是MySQL，Oracle,SYBASE還是Redis，MongoDB都是DBA，和他們沒關系。。。。。
1.打開nrpe.cfg，找到check_oracle_rman_backup_problems監控項，執行一下
cat /usr/local/nagios/etc/nrpe.cfg
2.找到check_oracle_health腳本（perl語言）監控的，那就打開看看是如何取值監控的唄
通過rman-backup-problems搜索到在@mode數組

並找到如下代碼，其中sql就是我們最終要找的，這是關於rman備份狀態監控
elsif ($params{mode} =~ /server::instance::rman::backup::problems/) {
$self->{rman_backup_problems} = $self->{handle}->fetchrow_array(q{
SELECT COUNT(*) FROM v$rman_status
WHERE
operation = ‘BACKUP‘
AND
status != ‘COMPLETED‘
AND
status != ‘RUNNING‘
AND
start_time > sysdate-3
});
} elsif ($params{mode} =~ /server::instance::rman::backup::problems/) {
$self->add_nagios(
$self->check_thresholds($self->{rman_backup_problems}, 1, 2),
sprintf "rman had %d problems during the last 3 days",
$self->{rman_backup_problems});
$self->add_perfdata(sprintf "rman_backup_problems=%d;%d;%d",
$self->{rman_backup_problems},
$self->{warningrange}, $self->{criticalrange});
現在知道這個是由於rman備份造成，那就執行下sql和備份日誌，發現如下錯誤
Deleting the following obsolete backups and copies:

RMAN-03009: failure of delete command on ORA_DISK_1 channel at 03/06/2018 01:15:28
ORA-19606: Cannot copy or restore to snapshot control file
知道錯誤，那就好解決啦，網上一搜總結如下：
CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f_bak‘;
crosscheck controlfilecopy ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f‘;
delete expired controlfilecopy ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f‘;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘/data/ora11g/product/11.2.0/db_1/dbs/snapcf_oradb2.f‘;
CONFIGURE SNAPSHOT CONTROLFILE NAME clear;
總結，這裏需要你能看懂perl面向對象編程，這裏package xxx相當於class 聲明類，new函數就是常說的構造函數，我覺的不會不可怕，不會可以去學，順便了解了一下perl語言，還是有收獲的
