The Oracle Application Server 10g Infrastructure - Infrastructure Log Reports

The following script can be run to display all of the iasdb logs in your system. Next is a handy script called display_all_log_tables.ksh that can be embedded into a shell script to extract all log messages into a flat file.

#!/bin/ksh
# First, we must set the environment . . . .
ORACLE_SID=iasdb
export ORACLE_SID
ORACLE_HOME=`cat /etc/oratab|grep $ORACLE_SID:|cut -f2 -d':'` export ORACLE_HOME

from

where
  table_name like '%LOG%'
and
  owner not in ('SYS','SYSTEM')
;
select 'spool off' from dual;

exit;

Note that once you have run this script and off-loaded all repository log messages, you can then use the UNIX grep command to extract selected contents. Next, let’s look at special types of iasdb repository log tables and see scripts to extract their messages.

The Application Server 10g servlet engine has several log tables in the repository that are used to track servlet errors:

• ose$http$admin.error$log This table contains the error message number and associated text.
  
•  ose$http$admin.event$log This table contains servlet event  
  numbers and their associated text messages.
  
•  ose$http$admin.http$log$ This is the repository log table that contains specific log information about remote user servlet messages. The table contains the remote user ID, time of the servlet request, and the referrer URL. The referrer column is most useful because you can use it to track the source of servlet requests.

SQL> desc ose$http$admin.http$log$;

Oracle Portal has several log tables in the iasdb repository, and these can be referenced with SQL to create developer activity reports for Portal. This produces a report similar to using the Oracle DDL system-level trigger, and tracks all Portal changes made by your development staff. The following report references the portal.wwlog_activity_log1$ and portal.wwlog_activity_log2$ tables and produces a useful report of all Portal development activity.

You can see the report output in the following listing. It shows the total number of rows processed by Portal developers, aggregated by date, and a summary of all Portal developer activity by date. This administration report is especially useful for change control tracking and quality control functions.

The iasdb repository also contains a wwlog_event$ table that provides total counts of Portal actions. This report is useful for Portal development auditing.

col c1 heading 'Action' format a20
col c2 heading 'Count' format 999,999
select
  action c1,
  count(*) c2
from
  PORTAL.WWLOG_EVENT$
group by
  action
order by
  c2 desc
;

The following listing shows the output. Here you see all of the Portal activities and total counts for each activity.
