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.
EugeneHi 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

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..
ThanksYou'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,
KevalHi 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! -
Hi All,
My database is performing very slow. Is there any thing which can tell me what is the state of my database and what problems it has and what kind of changes I need to do to make it better with respect Memory, Physical etc. I had enough SGA_MAX and SGA_TARGET defined around 2GB. I am using Oracle 10g on Windows.
Regards.

Okay... Let me put it in simple words.I do got what you said in your original post, you need to come back with the answers of the questions that I have asked you. Those answers would help us to guide you in a more better than giving "guesses" .
Is there any utility which runs and then generates a report stating that these are some problems found in my database. Like Row Chaining, water marks etc.
I told the "utility" , EM ! That's the only thing which would tell you the things in an easier manner with good looking charts and so on. Otherwise, things get back to teh manual part. One part is already given to you, Statspack , which you can run and get the information. The 2nd (and paid version, statspack is free) and more better version is, Automatic Workload Repository(AWR) which would do the same thing and would also give recommendation. This is a paid tool though and you should have Tuning Pack licence with you to use it.

% shared pool free problem in OEM database health
can u tell me what to do when the %shared pool free falls below 1% ..
what can be the solution.
if it is in the form of changing the shared pool size, how are the calculations done (in detail)?
other two parameters have values 99.99% and 98.95(buffer cache hit % and library cache hit %)user630185,
First look at things the other way round - if you have free memory in the shared pool, that means you have memory you are not using, why do you want to increase the amount of memory you are not using ?
Unless you can see a performance problem relating to a memory shortfall in the shared pool then you don't need to increase it. In fact, you could find that you introduce performance problems by increasing the shared pool if you are not making good use of shared SQL throughout your system.
Check for things like time lost on library and shared pool latches, CPU spent on parsing and "hard" parsing, successful use of the session cursor cache before worrying about the 1% free.
