Oracle datbase Health check

Hi All,
What you recommend for a Healthy database. What are the neccesary checks we do that our database is always healthy. What oracle recommends. Please explain your views.
Thanks & regards,
GK

Your question is roughly the equivalent to asking someone to teach you how to fly an airplane in three simple paragraphs.
There are books, hundreds of pages long, that do not adequately answer your question.
But two or three of those books and start doing the only thing that has been proven successful in learning this material. Read!

Regarding oracle 11g health check

Hi,
Does my oracle 11g health check checks the health of oracle 10g? The other way round is definitely not possible. But i was wondering if this were possible?

What "11g health check" are we talking about?

Oracle Applications health check

Hi,
I have to
1). Do health check of oracle applications 11.5.9
2). And recommend to upgrade to R12.
I always have these questions in mind. If a client is running happily on 11.5.9, what should be provided so the client will be convinced to upgrade to R12 (Apart from new features, security, performance).

I always have these questions in mind. If a client is running happily on 11.5.9, what should be provided so the client will be convinced to upgrade to R12 (Apart from new features, security, performance).We have same questions too, the main reason to move R11 to R12 is oracle will stop support soon *(As Hussein Sawwan mention)*. If possible you can share this information wiht your client:

Hi John I need your help regarding "Oracle EPM Health check" ?

Hi,
I need your views as we frequently start Hyperion services whenever it goes down (ex Workspace or EPMA or HFM).
These services most of the time after restart does not work properly.
Kindly suggest is it correct way to start only that service which stops or we need to bounce all Hyperion services?
Secondly how to validate my Hyperion Environment if is it working properly.
Version 11.1.1.3
URL check may be OK but sometime URL opens but problem occurs after login.

Thanks John,
I agree with you.
But situation is as we have multiple customers and multiple instances.
case 1: worspace went down ---restarting only workspace services; is it correct as we do mostly?
case 2: EAS and reporting may down---restrting only these two services; is it correct way to resolve issue?
case 3: HFM web services may down: starting IIS, www, http and HFM; is it correct to resolve?
we need to understand our resolution. OR we always go and stop Hyperion and start again Hyperion all services.

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..

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

Automatic connection "ping" / health check in TopLink JPA ?

Some days ago we experienced problems with our underlying Oracle database, so the DB server hat to be shut down and rebootet. The application server machine (running Apache Tomcat 5.5 on a Linux OS) which provides several web-applications that are using Toplink JPA were not restarted after the DB was up again.
We encountered several subsequent "connection reset" errors within the webapps which where produced by TopLink JPA. I'd assume that this comes from the underlying restart of the DB, which invalidated/closed TopLink's JPA connection.
is there any option e.g. to be set in persistence.xml to enable a Connection-"ping" or "health check" before TopLink JPA is using the connection?
e.g.
toplink.jpa.connection.ping = "select 1 from dual";
regards,
Hans

Hans,
There is nothing built in but you can use an ExceptionHandler to handle failures and re-connect connection. This is typically only an issue when using TopLink's internal connection pooling. It is more common in a container to use its data sources and rely on them to handle connection management.

Instance health check failing with errors

Hi
One of the instance showing " Agent connection is Instance is unavailable". How ever it is collecting and showing instance performance when I go to Performance pane.
When I check in emagent.trc file it is saying either agent/instance are running with different user than ORACLE or group not DBA.
Actually, in my case both are same.. l mean Oracle:dba.
I have bounce many times agent but no luck.
Your valuble comments helps greatly.
Here is error message

Symptoms
Caution:
The scope of this note is limited to Agents 10.2.x monitoring Oracle Databases running on HP-UX.
By default, the Agent 10.2.x is collecting the Healthcheck metric every 15 seconds. This metric basically gives an indication whether the monitored database is up and running.
On some circumstances, the Healthcheck metric cannot be collected. This results in such entries being added every 15 seconds to the $AGENT_HOME/sysman/log/emagent.trc log file:

Solution
There are several steps to solve this problem:
1. If the Agent Release is 10.2.0.1 or 10.2.0.2, upgrade the Agent to 10.2.0.3 and follow the steps below.
2. For HP-UX 10.2.0.3 Agent, here are the instructions to fix the problem while keeping the Healthcheck metric enabled. This section takes place in the Agent Oracle Home.
2.1. Download Patch 5854190 from Metalink.
2.2. Setup the Agent environment and shutdown the Agent by doing:

Hi All,

I am trying to do a quick health check of my instance. Since, I am running on oracle 8i, I believe, the time_waited column captured in ms, I might be wrong here.
Also, after seeing this stats, I though to concentrate on latch free wait events, but the major issue with these figure are, they can not tell, which session
suffered the most for latch free wait event and what time it happened ? Here, I am bit skeptical on how should, I go about this? I mean , where to look what in order to troubleshoot the issue. I know, few of you might recommend me to pullinmg out the statspack report and look out for top 5 wait events.
Yes, that can also, one of the way to see this problem. But , I would really appriciate, if somone could offer their valuable advise on below query excerpt, on how and where to look what in order to troubleshoot the issue.
