Undocumented Auto Task Health Monitor in 11g

Hi,
in the View DBA_AUTOTASK_WINDOW_CLIENTS is a column named Health Monitor.
How can i activate this Task (undocumented Parameters???, i tried disablehealth_check but without luck)
Thanks
Marco

HI,
the health monitor is a new package in 11g.
DBMS_HM
It is run by teh system automatically every time a critical error is encountered and can run health checks like block corruption check, data dictionray consistencey checks and so on. It is a hidden underscore parameter which manages the autotask and I will not tell you here which one, you must find out yourself!
Do not switch it off !!!! Its a great freature!
All information related to a critical error is put intot the Autimatic Diagnostic Rerpository (ADR) .
You can run health checks manually as well with the package.
Hope it helps,
BR,
Lutz

Health Monitoring. DBMS_HM issue.

Hi,
I am using ORACLE DATABASE 11g R2 (11.2.0.3) and Linux OS.
I was trying to monitor my database proactively(manually) using the package DBMS_HM. I referred the following link :-
DBMS_HM
and many others also but I am not able to get a clear understanding of the topic.
When i try to run_check 'Data Block Integrity Check' :-
{code}
DBMS_HM.RUN_CHECK('Data Block Integrity Check',
                    'DBIC',
                    'BLC_DF_NUM=1;BLC_BL_NUM=23456');
{code}
I got error :-
{code}
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
{code}
As per the documentation this should have worked.
I checked the data-dictionary views
{code}
SELECT a.* FROM v$hm_check_param a, v$hm_check b
WHERE a.check_id = b.id
AND b.name = 'Data Block Integrity Check';
8    BLC_DF_NUM    3    DBKH_PARAM_UB4         0    File number
9    BLC_BL_NUM    3    DBKH_PARAM_UB4         0    Block number
{code}
Can anybody help me with this problem ? else please provide me any good link to study database health monitoring in detail.
Thanks in advance.

Where is the third parameter I mean time out.. ?
I tried this and it worked..
DBMS_HM.RUN_CHECK('Data Block Integrity Check', 'ABCDE', 60, 'BLC_DF_NUM=1;BLC_BL_NUM=23456');
Cheers,
Manik.

ADRCI and Health Monitor Views

Hi, there,
Pardon me for being stupid, but I have (honestly) looked at the documentation before posting this thread.
I'm trying to housekeep some of the ADRCI relations - in particular, the Health Monitor runs.
I'm struggling to figure out how to list all of the hm_runs which are older than 7 days. I tried to use all sorts of variations on these times and I can't quite get it to pull things back:
adrci> query hm_run -p "end_time < sysdate-8"
adrci> show hm_run -p "end_time < sysdate-8"
I've even tried to 'select * from hm_run' in the command line tool, but to no avail. Have tried it via batch mode too (adrci exec="")
The other issue I have is that I noticed that if you do this:
adrci> purge -age 1 -type HM
This deletes the rows in the v$hm_run view in the database, but it does not delete the related rows in the v$hm_finding view. I suspect that it probably doesn't delete the related rows from the vm$hm_recommendation view either.
Is there a way to housekeep these two views? Or will they be taken care of by SHORTP and LONGP in the ADR Home control?
Mark

Hello everyone,
Can someone tell me where I can find extra info about the contents expected in the HealthMonitor.log file ? The installGuide and UserGuide describe only the HealthMonitor process but my customer would like to to send alarms when something goes wrong based on the content of the log file.

How to delete old runs from Health Monitor?

I am looking at the 11G built-in Health Monitor (http://docs.oracle.com/cd/B28359_01/server.111/b28310/diag007.htm), and have found that each run needs a unique name (ORA-48600: HM run with name [Dictionary Check] already exists).
I'm running them from the command line using a shell script - exec DBMS_HM.RUN_CHECK('Dictionary Integrity Check', 'Dictionary Check');
I want to run these monthly, and although I can create unique names that are date-stamped, over time these will build up.
Does anyone know how to delete the old runs?
There is no option from the command line in the documentation, or anywhere in OEM (12c) to delete them.
Thanks.

Default Job vrs Auto Task job

Under 11g, I am trying to work out what would be the benefit from assigning a scheduler job to the Auto Task Framework ( i.e. job class AUTO_TASKS_JOB_CLASS ) as opposed to just having a job under DEFAULT_JOB_CLASS.
What's the difference ? Is there pro's and con's or what type of criteria should be used when choosing what to schedule a job under ?
Jim

There are, it affects the jobs priorities and resources allocated for them, depending on their class.
Take a look at this: http://docs.oracle.com/cd/B28359_01/server.111/b28310/schedover006.htm

Health Monitoring and Restart Configuration with Node Manager

We have a WL 9.2.2 instance setup using Node Manager to control it. It contains a JMS server with a persistant store that is in an oracle database. If the Oracle database becomes unavailable, the Weblogic server throws a number of errors eventually leaving the Managed Server in a "FAILED" state. I configuring/activated the following "Configuration - Health Monitoring" options for the managed server to have it automatically recover from this situation:
Health Check Interval: 180
Auto Kill If Failed: Checked
Auto Restart: Checked
Max Restarts Within Interval: 2
Restart Delay Seconds: 0
However it is not automatically restarting, even though the server shows in a "FAILED" state.
1st question: Do I need to restart the server with the settings above to have it react to the FAILED state? I would think that 3 minutes after I configured the above it would begin a restart on the FAILED server, but that does not happen
I also note on the "Configuration - OverLoad" page, there is a setting for "Failure Action:" that can be set to "Ignore, take no action" or "Force Immediate Shutdown of this server" I did configure/activate this for "Force immediate Shutdown..." but again the currently FAILED server does not restart.
2nd question: Does this "Configuration - Overload- Failure Action" setting override or effect in any way the configuration of restart on the "Configuration - Health Monitoring" page?
3rd question: Same as 1st question but for these Overload settings: Do they require a full restart of the managed server to somehow take effect?


Have you set the field : CrashRecoveryEnabled=true in file : ..\bea\weblogic92\common\nodemanager\nodemanager.properties ?

Did you have Cloud start failures or a missing health monitor?

Calling all CQ Cloud'ers.
Hi, My name is Gary Gilchrist. I work with the engineering team for Adobe CQ Cloud.
Today I was running some diagnostics on our site. I see that there are a lot of you out there who have got as far as starting your own CQ Cloud. Congratulations!
But I also see a number of Clouds that have been attempted to be started by different tenants (that's you :)) and never made it as far as the "running" state. There are sometimes good reasons for this, sometimes related to configuration of your Amazon AWS key information. But we're still in Beta and I must admit, we know of a few bugs we still need to iron out.
I also see that some Clouds were started successfully, yet I do not see the automatic health monitoring that we record for your Cloud. We do that after a Cloud starts so that you can see the CPU, Memory and Disk health of your CQ instances running in your Cloud. You should see this as little green bars in your Cloud detail page.
I have two questions:
Did you attempt to start a Cloud (and you believe your AWS credential is valid) yet it failed to completely start up?
Did you start a Cloud successfully, yet you continued to see "unavailable" (gray bar) as the heath status for ALL the CQ instances in your Cloud? (please note that health monitoring for the Dispatcher is not working. It will fixed with our next update to the site, coming shortly).
If you did encounter 1 or 2 above please drop a reply on this thread giving only the name of your Cloud (no other personal information necessary) plus anything else you think is useful. We would like to look into it.
Thanks from the whole team here at Adobe for trying out CQ Cloud!
Gary.

Satellite P855-108 - PC health Monitor fails to update - Windows 8.1 update

Hello,
today updated to win 8.1 from a one year old windows 8, everything went fine
Then I followed Toshiba recommendations for updating the tools but despite doing exactly as explained the flash cards(and the functions buttons) are not functioning, they worked perfectly in win 8!
_The only utility that fails to update is PC health monitor,_ the version installed is 1.9.04.6402 and the one from support site for win 8.1 is 1.9.09.6400, when trying to install it fails with error message "not support"
When trying to open the installed health monitor there is also an error message "can`t get the bios type".
This is strange and every other utility recognizes the latest bios version 6.70 an the laptop`s details an serial
I tried all I could think about, installed flash card support tool from win 8, enabling and disabling in the bios, even installed VAP for win 8 but no change
Any help would be highly appreciated
Latest system driver and other tools are installed
Thanks in advance

Sorry for taking space on the forum,
_In case anyone is facing the same problem I managed to find a solution by my self,_
*it was caused by the old version of PC health monitor,*
uninstalled, updated to latest version
Now Function key utility and everything works as supposed, _the latest Health monitor also works fine_

Toshiba PC Health Monitor Compatibility Issues in Windows 8.1

Satellite L500-1XD - cannot find an update for PC health monitor

This TBS advises updates to PC health monitor and HDD/SDD alert.
HDD/SDD alert has a published update in the relevant downloads section but I cannot find an update for PC health monitor.
Any one got any bright ideas ?
Otherwise this seems quite a balanced system.

Hi Paolo30,
Thanks for your contribution. I agree with your model designation
I would like to download ver 1.5.6.0 but it does not seem to be listed on the download list (Two and a quarter pages long) for the L500-1XD on the Toshiba-Europe website. I am using I.E.8
Where are you seeing this listed ? Could you give me a URL please ?
It is an important update as it resolves a conflict between video streaming from HD and SMART HD messages as described in the TSB.
The only upgrade that is tagged as 1.5.6.0 is the Bullitin Board and this does not sound like the correct type of application. There was obviously a major update on 21/6/2010 there are 30 odd updates with that date.
Kindest Regards

Add a Human Task in BPEL but it shows as an Auto Task in BPA

Hi, all,
I create a BPMN flow in BPA and mapping to BPEL. And I add a Human Task in jDeveloper, and saved back to BPA server. But the problem is the updated BPMN flow shows that I added a Auto Task in BPA. Could you help me on that? Thanks in advance.
Best Regards,
Bill

Hi Bill,
Prefatory a quick intro on the basic idea of the BPA concept and a few personal recommendations. In general all changes on the control flow should be initiated top-down from the business process, which means your requirement becomes relevant only in certain cases. If the refinement of the BPEL process is going beyond the technical implementation, then the BPMN diagram itself needs to be corrected. That being said, in certain cases it may be sensible to make use of the improvement proposal feature (e.g. the IT developer recognizes the need of an additional service invocation, so that the control flow of the business process has to be refined).
Referring to your issue these changes are displayed as Automated Activities (abstract) in the superior business process (in BPA). For this reason some activities require a different approach when it comes to accepting or rejecting by the business users. The description below provides an overview about how-to add activities in BPEL subsequently (as improvement proposals) and how they will be represented in the superior business process after synchronization (personal recommendations).
Control flow
Email, Fax, Pager, Pager, SMS, Voice+
BPEL process (JDeveloper)+
Encapsulate within a separate Abstract activity - choose a name, which helps to identify that this should be a Notification activity (define naming conventions in the conventions handbook).
Business process (BP Architect)+
By default represented as Automated Activity (abstract).
Open the improvement proposal model and select the new activity. Go to Format/Representation and select 'Notification' in the Symbol-dropdown list - the object appearance changes.
Important: double-click the new activity and specify all the required parameters. Share the blueprint with IT.
Note: The attributes of the abstract Automated Activity still appear in the attributes view.
Invoke+
BPEL process (JDeveloper)+
Encapsulate within Abstract activities.
Business process (BP Architect)+
If encapsulated within an existing scope in BPEL - not visible in the superior process.
If encapsulated within an Abstract activity in BPEL - represented as Automated Activity (abstract).
Human Task+
BPEL process (JDeveloper)+
Encapsulate with an a separate Abstract activity - choose a name, which helps to identify that this should be a Human Task activity (define naming conventions in the conventions handbook). Ignore the Switch activity that will be added below the Human Task.
Business process (BP Architect)+
By default represented as Automated Activity (abstract).
Open the improvement proposal model and select the new activity. Go to Format/Representation and select 'Human Task' in the Symbol-dropdown list - the object appearance changes.
Important: double-click the new activity and specify all the required parameters. Share the blueprint with IT.
Note: The attributes of the abstract Automated Activity still appear in the attributes view.
Receive, Reply+
BPEL process (JDeveloper)+
Encapsulate within Abstract activities.
Business process (BP Architect)+
If encapsulated within an existing scope in BPEL - not visible in the superior process.
If encapsulated within an Abstract activity in BPEL - represented as Automated Activity (abstract).
Decide+
BPEL process (JDeveloper)+
Add a new Abstract scope - choose a name, which helps to identify that this should be a Business Rule activity (define naming conventions in the conventions handbook). Place an Empty activity inside the scope.
Business process (BP Architect)+
By default represented as Automated Activity (abstract).
Open the improvement proposal model and select the new activity. Go to Format/Representation and select 'Business rule function' in the Symbol-dropdown list - the object appearance does change.

Note: The attributes of the abstract Automated Activity still appear in the attributes view.
Flow, Switch, Pick+
BPEL process (JDeveloper)+
Only new branches within existing activities can be added subsequently. Each branch should contain at least one Abstract activity.

New activities should be defined in the superior business process.

If not encapsulated within a scope in BPEL - will be represented as Automated Activity (abstract).
If encapsulated within an existing scope in BPEL - not visible in the superior process after synchronization.
If encapsulated within an Abstract in BPEL - will be represented as Automated Activity (abstract).
