Excessive database timeouts. How to monitor?

Hi
There are excessive Timeouts being recorded on the database. using db console or OEM what is the best way to investigate this, and the reasons behind it?
Thanks.
Oracle 10.2.0.2.0.

not sure how you would monitor this in oem or dbcontrol. it may not be oracle timing out the session. from a troubleshooting aspect I would look at client sqlnet trace or maybe setup dead connection detection by setting / tuning sqlnet_expire_time in your sqlnet.ora which should help reduce timeouts.

How to monitor SQL Apply for 10.2.0.3 logical standby database

We have a logical standby database setup for reporting purposes. Users want to monitor whether sql apply is working or failed closely as it has reporting repercations.
In case of 9i databases , there was "Data Not Applied (logs)" metric which we used for alerting and paging, in case a backlog of more than 5 log files developed.
With 10.2.0.3 onwards, the metric no more exists.
I would like to learn from other, how to monitor the setup, so that if the backlog in logs shipping or applying develops, we get page.
Regards.

regather the statistics on the table with method_opt=>for all columns or for all indexed columns or whatever size 1
The 'size 1' directive will remove the histogram statistics.
Sorry, didn't read ur post in a hurry. Below article (http://www.freelists.org/post/oracle-l/Any-quick-way-to-remove-histograms,13) removes histogram without re-analyzing the table. Hope that helps!!!

using dbms_stats.set_column_stats.
I haven't fully tested it - it's only 10 minutes old, even if Ihave
slightly modified for you another script I've used for quite some
time - and the spool on 10.2.0.3 seems to confirmthat the histogram

How to monitor various databases using 10g OEM

I have Oracle 9i and Oracle 10g Databases. How can I configure Oracle 10g OEM to monitor all these databases. In Oracle 9i OEM it was easy. But I didn't find the method to add it in 10g OEM? Can we access the 10g OEM only through browser?
Regards

If you are installing Database and you choose to use Database Control, it is a different thing from Grid Control. Database Control comes with its one agent which is different from Grid Control's management agent.
If you install a database on different host and you do not have Grid control, you can use the database control for that database for that host. If you have grid control, then you can install the Management Agent separately on that new host to manage the new database as a Grid Control target.

How Track&monitor the history of executed sql /plsql on 10g database server

I want to keep and track the history of all sql/plsql that is being execute on database server. how it is to be done.
pls help
prabhaker

To keep track of executed SQL statements, you can use database auditing : see http://oraclelon1.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4007.htm#i2059073
I am not sure that PL/SQL execution can be traced using database auditing.

How to monitor OOM error

Hello Experts,
Periodically I'm having problems with some Enqueue-Locks and Communication Channels JDBC Sender stop processing messages.
Perform the procedure in item 29 of the SAP Note "831162 - FAQ: XI 3.0 / 7.0 IP / IP 7.1 JDBC Adapter" Communication Channels and JDBC Sender return to work.
I've checked the message size and the largest is only 1MB.
Also no error in the SQL Query in the database.
How do I track the OOM errors that generate the Enqueue-Locks?
Tks in advance.

Hi Pedro. How are you?
There is option of "Database Locks" in this path:
RWB -> Component monitoring -> Adapter Engine -> Engine Status button (near of CC Monitoring) -> Database Locks
Also you can see Java locks in the NWA tools (only PI 7.1, I guess).
NWA -> Availability and Performance Management ->Resource Monitoring -> LOCKS(system locks java).
I hope it helps you.
Best Regards.

How to monitor RFC to JDBC scenario?

How to monitor RFC to JDBC scenario
Hello,
I have update_insert scenario from RFC to Oracle database.
In TOC SXMB_MONI I have black and white flag.
In RWB I found for this scenario only successful status.
But in the database I found only 2 records from the 15 that I sent.
How can I monitor this problem?
What are the steps to investigate this situation?
Have a way to see the exact statement that I sent to the database?
Regards
Elad

Hi Elad,
If nothing can be seen in the Adapter monitor...go to the Database.
Oracle has various developer\system tools that can allow you to get information.
For example Oracle has the TOAD tool which allows you to get the SQL trace of the treatment the XI actually send.
see if the SQL interpreted by the JDBC adapter was really what you meant.
Good luck.

How to monitor Radius services on ACS 5.4

Hi All,
I want to monitor Radius services of ACS 5.4, In case of failure any radius service on ACS.
ACS should send alert to Syslogs or email notification
Is there any way to monitor Radius services ? Anyone have any idea how to monitor.
Regards.

Hi Narinder,
I dont think so there is any particular way you can do that, Because ACS 5.x doesnt have any particluar Radius service.
The services which are available and can be viewed through CLI and GUI are following:
Database
Management (ACS management subsystem)
Ntpd
Runtime (ACS runtime subsystem)
View-alertmanager
View-collector
View-database
View-jobmanager
View-logprocessor

RE: How to monitor who has what service objectconnection?

We ran into this problem, specifically because we are using a dbsession
connection pattern and the dba's did not like loosing control over
connections. We have 8 subsystem, each with a dedicated connection that
is shared across multiple users. We also have a security pattern in
place that is token based. Since we have to pass a security token
through service objects we can track this information using a
"connection array" on the service object and a system agent to poll the
contents of the array. When a sql statement is invoked on a
persistence object we add the user to the array on the persistence
manager (SO). When the sql is complete we remove the user from the
array. Since the PO has a system agent we can ask the system agent at
anytime, who has an open connection/session with the PO. Since system
agents plug into econsole, the dba can go look any time.

Subject: How to monitor who has what service object connection?

Here at Eli Lilly & Co., we have a customer that would like to know if
anyone out there has successfully
devised a method to be able to tell what user has what service object
connection. Basically, if a customer
calls the system administrator with a problem with the application, the
system administrator would like to
be able to kill certain processes. Right now, the database connections
running on the server all look the same.
Some ideas were generated internally, one referring to setting up agents
but we'd like to see if anyone
has had success in doing this already that we could use as a contact.
Thanks,

Hello Peggy,
I suggest that you make contact with Paolo Sidoli at DS Data (Italy). They
have written a very nice package called DORE that includes trouble shooting
utilities, that allow you to monitor what a remote user is doing (you can
actually see their screen!).
You can contact Paolo at [email protected]

How to monitor a specific transaction in Solution Manager ?

Hi all,
I have configured the Service Level Reporting and it works correctly.
But i don't know how to monitor a specific transaction like SM21, DB02, FB01N etc... ?
In the SL Reports configuration steps, we can configure this option : Select Business Processes For SL Report. I did a lot of tests but it does not work.
Have i to configure the Business Process Monitoring ?
Thanks.

Hello,
it depends a little on what you want to do. If you use the pure CCMS monitoring with the table ALTRAMONI you get average response time per instance and you only get new measurements once the status changes from green to yellow or red.
In order to get continuous measurements you should look into Business Process Monitoring and the different documentations under https://service.sap.com/bpm --> Media Libary --> Technical Information. E.g. the PDF Setup Guide for Application Monitoring describes this "newer" dialog performance monitor. Probably you have to click on the calendar sheet in the Media Libary to also see older documents as well. As the Business Process Monitoring integrates with BW (there is also a BI Setup Guide in the Media LIbrary) you can get trendlines there. This BW integration also integrates back with SL Reporting.
Some guidance for SL Reporting is probably given under https://service.sap.com/rkt-solman but I am not 100% sure.

Volker
