DS6 instance reaches 50% CPU utilization after restart

Hi,
I am running DS6 on Solaris 10. I noticed that after every orderly restart slapd process reaches 50% CPU utilization. This situation lasts for about 5 min. What do you think it is?
Thank you.

At Startup Directory Server does initialize some of its caches :
- ACI
- Roles
- Class Of Service.
- Groups (for the new isMemberOf feature).
Depending on your configuration these searches may take a little bit of time and cpu.
Regards,
Ludovic

Increase in CPU Utilization after migration from APEX 3.1.2 to APEX 3.2

Has any noticed any increase in CPU Utilization after migrating from APEX 3.1.2 to APEX 3.2?
Thanks,
Mark

Hi Mark,
Take a look at some of the usage reports within APEX (sessions, page views etc) to get an overall feel for where the time is being consumed.
You'll also find it useful if you can run a statspack report (or AWR, ASH etc) during a busy period to be able to drill down into where that CPU is being spent.
There's no magic answers here unfortunately, you need to track it down to where the time is being spent before working back up to find out where best to tune it.

Heavy CPU Utilization of Dictionary Query - After 9i to 10g Upgrade

Hi Friends,

After migration Exchange 2013, MBX server, CPU utilization is so high

CPU utilization become so high this morning after migration into Exchange 2013,
Some healthy DBs is getting disccounetced with growing replay Queue length, mounted DB is no issue.
It seems that's short of CPU performance,
Are there any processes to limit or set up to reduce the load of CPU, MBX servers? It's temporary treatment...

What's the CU level you have for your Exchange 2013? Also, please check node runner processor as Node Runner process can cause CPU utilization issue. I would also suggest to check your disk IOPs as it looks like disk IOPs issue to me as well. Thanks.

Increased CPU utilization on Sup1A after upgrade

Hello,
I recently upgraded a 6009 with Supervisor 1A from CatOS 7.6(5) to 8.4(4). Baseline total CPU utilization before the upgrade was about 12%, post upgrade it sits at about 30%.
We have several similar switches throughout our network that we intend to upgrade as well, so are treating this one box as a testbed. We will soon deploy IP telephones to every desk in our network, and want to determine if this higher baseline utilization will be problematic for us.
Considering voice, should we be concerned about this? Will any changes due to voice deployment such as many trunks, QoS, etc. cause a significant jump in CPU that might put our baseline even higher?
Will the higher baseline CPU utilization affect switch performance? I know most forwarding functions do not depend upon the CPU, and are switched via ASIC.
thanks for the help,
Brad

The IDLE_Tasks process on which you are seeing a slightly higher CPU is actually an enhancement that collects information more effectively on crashinfo files (files generated when there is a crash on the box). This enhancement went into 8.3(x) and 8.4(x)
In the past "IDLE_tasks" processing was not counted and therefore belong to the "kernel and IDLE" process (which as you can see in the show proc cpu) accounts the amount of cpu not being used.
If you are upgrading other 6500's with Sup1a's make sure they all have 128MB DRAM just like this one has.

Limits are changing in Instance config file after restart (Sometimes)

Hi Experts,
Here I have one problem.
The configuration limits are changing to original limits after restarting of the server
Ex: Initial Given Limit : <DefaultRowsDisplayedInDelivery>75</DefaultRowsDisplayedInDelivery>
I changed to <DefaultRowsDisplayedInDelivery>1500</DefaultRowsDisplayedInDelivery>
After restart, some times the configuration is changing to initial stage
<DefaultRowsDisplayedInDelivery>75</DefaultRowsDisplayedInDelivery>
Similarly the Download limit also changing <DefaultRowsDisplayedInDownload>2500</DefaultRowsDisplayedInDownload> from 2500 to initial value
Can anyone help me in regardin this?

Performance degrading CPU utilization 100%

Hello,
RHEL 4
Oracle 10.2.0.4
Attached to a DAS (partition is 91% full) RAID 5
Over the past few weeks my production database performance has majorly degraded. I have not made any application, OS, or database changes (I was on vacation!). I have started troubleshooting, but need some more tips as to what else I can check.
My users run a query against the database, and for a table with only 40,000 rows, it will take about 2 minutes before the results return. For a table with 12 million records, it takes about 10 minutes or more for the query to complete. If I run a script that counts/displays a total record count for each table in the database as well as a total count of all records in the database (~15,000,000 records total), the script either takes about 45 minutes to complete or sometimes it just never completes. The Linux partition on my DAS is currently 91% full. I do not have Flashback or auditing enabled.
These are some things I tried/observed:
I shut down all applications/servers/connections to the database and then restarted the database. After starting the database, I monitored the DAS interface, and the CPU utilization spiked to 100% and never goes down, even with no users/application trying to connect to the database. The alert.log file contains these errors:
ORA-00603: ORACLE server session terminated by fatal error
ORA-00600: internal error code arguments: [ttcdrv-recursivecall]
ORA-03135: connection lost contact
ORA-06512: at "CTXSYS.SYNCRN", line 1
The database still starts, but the performance is bad. From the error above and after checking performance in EM, I see there are a lot of sync index jobs running by each of the schemas and the db sequential file read is high. There is a job to resync the indexes every 5 minutes. I am going to try disabling these jobs tihs afternoon to see what happens with the CPU utilization. If it helps, I will try adjusting the job from running every 5 minutes to something like every 30 minutes. Is there a way to defrag the CONTEXT indexes? REBUILD?
I'm not sure if I am running down the right path or not. Does anyone have any other suggestions as to what I can check? My SGA_TARGET is currently set to 880M and the SGA_MAX_SIZE is 2032M. Would it also help for me to increase the SGA_TARGET to the SGA_MAX_SIZE; thus increasing the amount of space allocated to the buffer cache? I have ASMM enabled and currently this is what is allocated:
Shared Pool = 18.2%
Buffer Cache = 61.8%
Large Pool = 16.4%
Java Pool = 1.8%
Other = 1.8%
I also ran ADDM and these were the results of my Performance Analysis:
34.7% The throughput of the I/O subsystem was significantly lower than expected (when I clicked on this it said to either implement ASM or stripe using SAME methodology...we are already using RAID5)
31% SQL statements consuming significant database time were found (I cannot make application code changes, and my database consists entirely of INSERT statements...there are never any deletes or updates. I see that the updates that are being made were by the index resyncing job to the various DR$ tables)
18% Individual database segments responsible for significant user I/O wait were found
15.9% Individual SQL statements responsible for significant user I/O wait were found
8.4% PL/SQL execution consumed significant database time
I also recently ran a SHRINK on all possible tablespace as recommended in EM, but that did not seem to help either.
Please let me know if I can provide any other pertinent information to solve the poor I/O problem. I am leaning toward thinking it has to do with the index sync job stepping on itself...the job cannot complete in 5 minutes before it tries to kick off again...but I could be completely wrong! What else can I check to figure out why I have 100% CPU utilization, with no users/applications connected? Thank you!
Mimi
Edited by: Mimi Miami on Jul 25, 2009 10:22 AM

Tables/Indexes last analyzed today.
I figured out that it was the Oracle Text indexes synching to frequently that was causing the problem. I disabled all the jobs that kicked off those indexes and my CPU utilization dropped to almost 0%. I will work on tuning the interval/re-enabling the indexes for my dynamic datasources.
Thank you for everyone's suggestions!

this is obviously an internal process consuming all the CPU power, as Jamie already pointed out restarting the appliance may fix the problem, however before doing that you could open a support request have customer support look into that, to make sure not to whipe out any traces. You might also check the following things:
GUI: Monitor->System Capacity->Incoming Mail   Is the traffic or the number of concurrent connections always high? In this case there might be a capacity problem
CLI: status detail      Are there a lot of messages in the quarantine (several 10.000)? Lots of active recipients? May indicate a problem with the internal database or reporting.
A stuck database or workque process would go away after a reboot, a capacity problem, however, won't.

SDK-based Management Pack causes 100% CPU utilization for HealtService.exe

We developed an MP that uses SDK to create SCOM objects and insert a large number of performance counters ~ 2000 every 5 minute interval.
On SCOM side the MP has about 2000 instances of UnitMonitor (only ~20 per class but there are lots of actual objects). In these monitors we use
DataSource based on Microsoft.SystemCenter.TargetEntitySdkPerformanceDataProvider. All worked fine for a year but lately added a bunch of new objects/counters and CPU utilization for the MonitoringHost.exe started to spike
to 100% a few seconds after the Performance Counters were posted via SDK. The spike lasts for up to 3 minutes. No DB or Network spikes observed. We suspect SCOM does not deal efficiently with SDK Performance data - as if a separate SdkPerformanceDataProvider
is started for every UnitMonitor when the counters are posted rather than having cooked-down - one per Target instance.
Can anyone shed some light on this? I suspect only the Microsoft engineers would know.
Our environment is like this:
SCOM 2012 R2 UR4
Windows Server 2012 8 Core, 16 GB Ram
Thanks,
Dave

Hi Dave,
is there a way that you can reduce the number of performance insertions? Regardless of even fixing the performance issue, the impact from a database standpoint may be something to consider in the long term. My point is that fixing one issue, will take us
to the next one, etc etc.
I would reduce the number of insertions, only to the either insertion of the "most critical" or "top #". Also, aren't those counters already captured out of the box?

High CPU utilization with SQL Server 2005

Our company recently combined our DBs into one SQL 2005 Server.
Dell Power Edge 1800 with 3.00 GHz Xeon Processor 800 FSB, 1 GB of RAM
Dell Power Edge 1600 with 2.80 GHz Xeon Processor 533 FSB, 1 GB of RAM
Combined into one:
Dell Power Edge 2950 Dual Core 1.6 GHz Xeon Woodcrest Processor, 4 GB of RAM
However, the CPU utilization on this new server is maintaining at about 90% with 3.82 GB of RAM used as well. It's a Windows Server 2003 R2 x64 edition running SQL Server 2005 SP2 x64. I have searched around Microsoft's website for any information that could be of help to me, but I was unable to locate anything. I was hoping that someone could provide some insight as to why this might be occuring. Or if this is a known issue.
Thanks,
Peter

Hello!
Here are some steps to take after upgrading your SQL Server from 2K to 2K5. (This quote is from BOL)
After upgrading the Database Engine to SQL Server 2005, complete the following tasks:
Register your servers - Upgrade removes registry settings for the previous SQL Server instance. After upgrading, you must reregister your servers.
Repopulate full-text catalogs - The upgrade process marks your databases as full-text disabled. Catalogs must be repopulated, but this operation is not run automatically by Setup because it can be time-consuming. As this operation enhances the performance of your SQL Server 2005 installation, administrators should plan to repopulate full-text catalogs at a convenient time.
Update statistics - To help optimize query performance, we recommend that you update statistics on all databases following upgrade. Use the sp_updatestats stored procedure to update statistics in user-defined tables in SQL Server 2005 databases.
Update usage counters - In earlier versions of SQL Server, the values for the table and index row counts and page counts can become incorrect. To correct any invalid row or page counts, we recommend that you run DBCC UPDATEUSAGE on all databases following upgrade.
Configure your new SQL Server installation - To reduce the attackable surface area of a system, SQL Server 2005 selectively installs and activates key services and features. For more information on how to activate SQL Server 2005 features, see SQL Server Surface Area Configuration.

[iPhone] CPU utilization

Hi all , do you know how to get the CPU utilization of the iphone through the code? Thanks very much.

I called Apple Support today and they instructed me to follow the same article. Follow it closely (use the detailed steps). It did work for me.
I did have a lot of trouble unistalling the bonjour service. It did unistall without error, but the service and the directory and app and DLL where still left. I could not delete the DLL, even after the restart. I manually removed the service and rebooted again, still no luck. I even ran a windows systool to look for open file handles to the DLL and found none... So, I can't explain why I couldn't delete it.
Other than that, the instructions went smooth. I simply ignored the bonjour issue, reinstalled, and my problems were solved.
Before unistalling, I would export my library (just in case). Do this from File --> Library --> Export. This may help you preserve you playlists if something goes south.
Also, I would backup all of my library in the MyDocument --> MyMusic --> iTunes Folder.
I didn't need either of the above, iTunes was able to read all of the original files and preferences when reinstalled. But it's better safe than sorry.
