I like your plan a lot. I'd like to hear about you accomplish step 2. I already use a centralized monitoring database to store statistical data and use Excel to graph the results (or I was doing this last time I worked with Oracle - still looking for my next position!).

The article is at http://www.oracle.com/oramag/webcolumns/2001/index.html?diy_dynamic.html. If you have 8i or above this would work for you. Basically, it allows you to read flat files with a 'SELECT' statement. I've been thinking about a tool like this, too. My plan is something like this: 1) Create a 'DBAMON' database instance. This instance needs current database links to each instance you want to monitor. 2) Write the scanning algorithm in PL/SQL, and store it in the DBAMON instance. 3) Create a DIY$ view in each database. A DIY$ view is kinda like but not quite the flat-file select in 9i. A DIY$ view is file-specific. So you create a view and call it something like DIY$ALERT_LOG in each database instance, and each instance knows where the alertSID.log file is and how to read it. 4) Create a job using DBMS_JOB in the DBAMON database to periodically scan each instance's DIY$ALERT_LOG view and look for errors. 5) If the job finds any errors, use the UTL_SMTP package to send you an e-mail, or beep your pager, or whatever. The beauty of this method is that it's all done from inside Oracle, and doesn't rely on outside factors such as WinBatch, ksh, csh, sh, Kix, bash, or Perl (sorry, Jared). My DBAMON database is on my NT workstation, and I can read alert_SID.log files from both NT and UNIX operating systems. So far, I've got step 1 done, step 3 done on a test database, and am working on step #2. Film at 11:00 if you're interested. Remember, YMMV!

Vergara Oracle DBA Guidant Corporation (909) 914-2304 -----Original Message----- Sent: Monday, January 07, 2002 10:58 AM To: Multiple recipients of list ORACLE-L Hi All, Currently I am the only DBA for the 15 productin databases in our company. I have written shell scripts on all database servers to parse the alert.log file and look for Oracle errors and send page/E-mail if problems are found. While this works it is sometimes painful to maintain - if I want to change something I have to go to different servers to change the scripts one by one. I figure it would be nice if we can have a centralized solution where I can monitor alert logs remotely and don't have to hop from server to server. Are there any tools/scripts that enable DBAs to do this? I know OEM can do that with the Advanced Events but now you have to buy the Diagnostics pack for that.
