Запросить более 1 базы данных в DB2 v10

Eigen

Я пишу сценарий аудита, который сначала собирает информацию на сервере Linux, а затем подключается к экземпляру DB2 v10 через CLI db2 для выполнения запросов. Отлично работает с одной базой данных на сервере. Я создал другую базу данных и запустил скрипт. Теперь мои результаты смешивают ответы из обеих баз данных.

Я попытался подключиться к первой базе данных через DB2 CLI и запустить сценарий, но результаты все еще неоднозначны. Как я могу получить результаты для каждой базы данных или иным образом четко указать, какой результат из какой базы данных, когда это необходимо? У меня не будет заранее названий баз данных, потому что я внешний аудитор.

Ниже приведен фрагмент кода, который я запускаю после того, как получил информацию о локальном сервере Linux / AIX и начал подключаться к DB2:

Если вы просто хотите записать имя базы данных в отчетах ($ logfile), то у вас уже есть имя базы данных в вашем скрипте (в переменной управления циклом $ i).

Если вам нужен один $ logfile (включающий все базы данных, что представляется сомнительным решением), тогда эхо-колонтитулы выводятся в $ logfile после успешного соединения db и после отсоединения / connect-reset из этой базы данных. Все, что находится между заголовком и нижним колонтитулом, будет относиться к этой базе данных

Другой вариант - иметь один $ logfile на базу данных, например, $ dbname. $ Logfile, что может быть проще, особенно в отношении владения базой данных для разных групп / сфер ответственности в организации.

Один из способов, которые я сделал, заключается в следующем.

os_info=$h_name,$os_name,$os_mversion   # paragraph grep'ing is not possible in Linux, use Perl version db2 list db directory | perl -00ne 'if ($_ =~ /Indirect/) ' | grep -i alias|awk {'print $4'} | while read DB_NAME do  db2 connect to $DB_NAME >>/dev/null is_connected=$(db2 connect to $DB_NAME | awk {'print $1'} | head -1) #echo $is_connected if [ "$is_connected" = "SQL1776N" ]; then echo '-1, *HADR Secondary*' > xcvsfdgerwersdfs.dat else db2 "CALL GET_DBSIZE_INFO(?, ?, ?, -1)" | grep "Parameter Value" | head -2 | tail -1 | awk '' > xcvsfdgerwersdfs.dat fi  db_size=$(cat xcvsfdgerwersdfs.dat) echo $os_info,$db2_version,$DB2INSTANCE,$DB_NAME,$db_size  done

У меня есть базы данных в Linux и AIX, поэтому я использую фрагменты Perl для определенных вещей. Я использую каталог DB2, чтобы найти / идентифицировать доступные БД и собрать их информацию.
