The Database is Shutdown, no user is complaining about it and also you are not monitoring it through alert log file, then how will you, as a DBA, come to know about it?

I'd like the tool alerts me by email if something goes wrong.

Provide me some sql queries or scripts which shows that process are over loaded and memory needs to be allocated, queries are taking long time , i/o operation are more instead of memory.

I am monitoring out PROD database using EMCA database control.
Under "Performance" tab I check the AVERAGE ACTIVE SESSION and I see spikes of "CPU concurrency". (figure emca1)
figure: emca1>
[URL].......
I want to investigate what causes this "spike" in cpu so I drill it down further:
figure: emca2>
[URL]........
Then figure drill down further:
figure: emca3>
[URL].......
But I can not understand what causes the spike thing.
which tools are available for monitoring load of the database?

View 7 Replies View RelatedI have to apply monitoring template on my databases. Databases are already added and configured into OEM. They are visible under Databases tab and also under Groups where I have added them.
But when I try applying monitoring template and look for database in search window, it doesn't appear there.
My manager is asking to create a SQL scrip, which will provide following information.
Our database is 9.2.0.7.0 on Windows 2000 Server
-How many records Insert / Update or Delete daily in my Oracle database?
- Check Archive log / Redo Log switching information?
-Check database growth ?
I'm using this logic to avoid specific error.Does not seem to be working fine. Any other method to exclude perticular error from monitoring.
if [ -n "$line_no1" -o -n "$line_no3" ] ; then
cat $script_loc/alrt_chk.log | grep -i "ORA-" > $script_loc/ora_alert_only.log

echo "Entering in while Loop"

View 9 Replies View RelatedI've got a pl/sql procedure that i would like to monitor its progress. Its been running for quite a few hours now and i dont really know if it is stuck in a loop or if it is just taking too long read/execute queries. Is there a way to find out what is the status of the procedure? or what it is currently doing?
I looked at views like v$sessions or v$session_longops but they dont actually tell me what it is currently doing. All of them just point to the call to the pl/sql procedure. Also, is it possible to look at the physical files on the filesystem to know if there is actually any processing going on and files are being written to? Is this possible or a files written to only after a commit?
11.2.0.1Aix 6.1 5L (quadcore, 16GRam) I am still confused how to take full advantage of these monitoring tools. Actually the our database performance is currently satisfactory, except for occasional few minutes spikes of CPU highs > 80 .I just want to catch the culprit process/program responsible for this spikes. Is it wise to run ASH, AWR, ADDM with an input from time 1AM to 1AM next day? What I mean is I will analyze a 1-day period, so that I can catch the program/process that has the higest cpu/memory usage for the day.
View 24 Replies View RelatedI'm running Oracle EE 11.2.0.2 and when I look in OEM SQL Monitoring, it shows nearly every sql statement running with a degree of parallelism of *2*.
I've checked dba_tables and the 'degree' for all tables is only 1. I look at the actual sql statement, and there are no hints to tell it to use parallelism. So why and how is the database using parallelism?
I do see that parallel_threads_per_cpu is set to 2, but this is default for our Solaris 10 operating system.
REF: (for 11.2)
===========
PARALLEL_THREADS_PER_CPU specifies the default degree of parallelism for the instance and determines the parallel adaptive and load balancing algorithms. The parameter describes the number of parallel execution processes or threads that a CPU can handle during parallel execution.
The default is platform-dependent and is adequate in most cases. You should decrease the value of this parameter if the machine appears to be overloaded when a representative parallel query is executed. You should increase the value if the system is I/O bound.
how to tell if my database is actually IO bound or not?
get all the unused index in the system , if i put this query in batch job and execute it every night upto one months and store its data in a table and after one months i can get all the used indexes and left would be our unused indexes.
select
distinct p.object_name c1
from
dba_hist_sql_plan p,
dba_hist_sqlstat s

When I monitoring db, I see open cursor increase from a machine running Java application. On the develop machine, everything is ok, but on the production server, open cursors can not close.Although the parameters are the same on 2 servers.

View 3 Replies View RelatedI am using TOAD to monitor user sessions. I have a user who uses nearly 80% of Overall resources in the mornings. He calls me daily and say that his work is done. But even then the TOAD shows that he is using same resources for some time.
My question is can i kill the session once he confirms his work is done OR do i need to wait till the redologs are cleared.
Currently all my tablesapces are "UNIFORM" and I am looking into going to "AUTOALLOCATE" so space will not be some much of an issue.
I am using the following code and here is the output
sqlplus -s / <<-EOT
set pages 50
set line 100
set verify off
set feed off
set trimspool on
[code]........
Have a script that can emulate my above output and also deal with tablespaces that can autotallocate?
Oracle on 11gR2 on hp-ux 11.23.Need to develop a shell script which will do a monitoring of the alert log daily.
It should do a audit trail (only check for warnings/errors) for the last 1 day daily till collection time and output to a file.if no errors should output "No Errors/Warnings", else ouput the relevant.
We are on oracle 11.2.0.2 on Solaris 10. I dont have acces to the db server but connect to the db from the client side using sqlplus. though I have dba privilege (at oracle level) but no access to db server at os level. I also dont have access to enterprise manager console where such information is available.
I want to set up monitoring so that I can get a mail when the space falls below some threshold like say tablespace is 90% full. Is it possible to get mail from pl/sql script for example?
we can't use the Exadata Plugin for Cloud Control but we need some monitoring of the Cell Servers.Does OS Watcher is the right tool or do we need ADRCI for incidents and so on.
What do have to install and what information do we get.
I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site
