Database Health Check Enquiry

Hi all,
Some enquires regarding database health check. I did some research regarding health check, got overwhelmed by the information available out there.
Currently I don't have any report on hand, but currently working and starting on one. This report serves as a report for reference, to understand if there's any database performance issue, and as a report for management.
Wish to check with you folks, what are the typical things that I can look at on a daily basis to understand my database health status, eg. Buffer Hitrate, database I/O etc, especially those that may/will contribute to impact on the database performance. Or is there any good reference link whereby I can do some readup regarding such a health check?
Thanks in advance for any input.
Eugene

Hi Eugene,
Well that's a pretty open question and I guess you will get a lot of replies which I look forward to monitoring as there should be some very interesting ones there.
Anyway, let me just open with one point that I have found very useful in the past. As regards Database Performance , you can look as much as you like at the statistics and a great deal of discretion is required in interpreting them but the real test for me of how well a database is performing is in terms of the user (or application) perception. Are the responses from the database good enough to meet the users expectations. Check the average response time for example and set guidellines for what is acceptable, very good response , very bad response etc.
I use this as a guideline so then once the database is perfoming in the sense that the user is satisfied (or better still happy with the performance) we can gather the statistics (from Oracle 10g onwards there are lots of tools built in like ADDM and AWR for gathering and storing the database statistics) and create baselines. Once we have baselines for a normally performing system, as soon as problems are reported we can run off a diagnostic tool like ADDM for that period , compare it against the baseline and look for the striking differences. From there we can start an analysis of individual numbers, buffer hit ratios etc. to delve further.
Hope this helps , I am sure lots of other people will chip in to this
Regards

Database health check

Hello Gurus,
I have got an opportunity to do database health check in a concern.
Is there any tool or script to do health check commonly in an organization?
Is there any procedure to follow?
Kindly help in this issue.
Best,
Balu.

Database health check or Sanity check covers following topics (learnt from Niall Litchfield) :
1 Space Management
2 Backup Management
3 Security
4 Transaction Management
5 Statistics Management
6 Errors
7 Performance Management
8 CONCLUSIONS
Please check below documentation link also :
http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/diag007.htm
Database health check is nothing other than organizing all your monitoring scripts to display at the same time such as (buffer cache hit, library, dictionary, parse, soft parse, hard parse, iostats etc etc.) If you have OEM with performance pack, there is a module there that is captioned database health check. You can use it to get a bird's eye view of your instance.

Graphical Reports for Database Health Check or Database Statictics

Hello
we are using oracle 10g on Solaris.
Is there a way I can get the Database health check or database statictics report in graphical form like to represent the growth of database (in a week or month), log size etc..
Thanks

You'll have to develop your own method/application/script as per your requirement. To some extent Enterprise manager may help you but I think this is not your requirement.

Cisco ISE database health check

We had a situation where the DB was corrupted in the process of doing an ISE upgrade from 1.1.4 to 1.2. As a result of which the entire network was down.
Is there a way to monitor DB health on regular basis just so as to avoid the above situation in future?
Thanks,
Keval

Hi Keval, can you provide more information on what exactly happened when the DB got corrupted? I have done several upgrades from 1.1.x to 1.2 and as long as I followed the upgrade procedure I never had any issues.
Otherwise, to answer your question, the access to the database is restricted so I don't think there is a way to monitor/query the DB from an external system. This is why it is very important to have backups! :)
Thank you for rating helpful posts!

Oracle Database Audit Health Check

Hi Experts,
I have been looking for checklist to perform the oracle database audit.
what is the best practise to perfrom the database audit health check.
Regards
Mohammed. Abdul Muqeet

Hi,
What is it mean for Health Check, You mean you have audit enable in your database and you want to manage it. if so
then you have to take care of Audit area at OS level and sys/aud$ table
for Audit Area: you can schedule a job to clear that are time to time
for sys.aud$: Move this table to non- system tablespace and moniter the uage. can purge the data if not required after taking the backup..

Ora9i database monitor health check thro diagnostic pack

Hi,
It was quite long time since, i could not able to monitor the database health for all the databases through enterprise manager console--standalone mode ---. Even i tried with connection through intelligent agent and the default is client connection. can any experts guide me to fix this issue please.
Thanks n advance
efshafi

hi,
Thanks for the prompt reply. The database version is 9.2.0.0 from standalone enterprise mode. I can able to connect and go inside to check the instance, schema, security, etc but on the sublevel of instance management to monitor the database health, it again ask for the usernname, password, service name, connect as. While I log in sys password service name and connect as sys dba. without any error message it comes out the session.

In TOAD, Need to Enable DB Health check option

Hi,
I am using TOAD 10.1.1.8 DBA Suite.
As my TOAD DBA Suite, DB Health check option should be there under
Database -> Diagnose -> DB Health Check.
But its not showing this option.
Kindly guide me as How to enable DB Health check.
Expecting your valuable reply.
Thanks in advance,
Orahar.
Edited by: Orahar on Feb 10, 2010 3:06 PM

Sure.
As I didn't get any valuable response from TOAD Forum, I have posted here.
I hope, I will get the solution here at OTN.
Thanks.
