Oracle Memory utilization gradually increasing up to the max in short span

Hi All,
Our Oracle database running in windows 2000,having max sessions of 1500
attains it max_memory 850m once 1500 sessions reached.
--Shared pool memory(SQL AREA,LIBRARY CACHE,SHAREDPOOL MISCELL.,) gradually increasing.
Oracle database version:9.2.0.5
Server Type: Shared Server
Os memory: 1Gb
Oracle memory: sga-750m,pga(max) -110 allocated by oracle when no of sessions increasing.
Pls tell me why it is happening?

Hi Priyanka,
Its know problem in solaris zones , 40 GB Memory is allocated to global zone & you db server zone has been assigned a part of it .
Get is touch with you Solaris admin to know exact memory allocated to db zone , as per my knowledge they must be shared across multiple zones
use below from Os prompt
prstat -ZThanks,

请教一下，这个Oracle Memory Utilization显示的百分比是Oracle已经使用的内存占总物理内存的百分比吗？99%意味着什么？如果不是，怎么样查看Oracle占用的总内存大小？

FB03 - Increase length of the field "Account Short Text" in FB03

Dear Expert!
I understand that Tcode: FB03 is SAP standard tcode. However, i just want to ask, is it possible to increase length of the field "Account Short Text" to 42 characters in FB03? Because my vendor/customer name is quite long, and when i view via FB03, the field "Account Short Text" only displays 20 characters, not full vendor/customer name. Unless, i double click on the line item, then i can see full vendor/customer name. But i want the "Account Short Text" field can display full vendor/customer name.
Is that possible?
Thank you very much.
LeLinh

Hi,
there's a matadata table behind it RFPSD and for Account short text field KTEXT is used, which in fact has a length of 35 chars.
But on the other hand there's also a filed KTEXT_GL (G/L Account Short text) which is maybe applied here. It has a length of 20.
You can do some more checks on program to clear it finally

RAM utilization keeps increasing over time

Environment: SharePoint Server 2010 on a stand-alone server, total RAM: 24GB
I noticed that on our server the RAM utilization keeps going up until it gets to about 94-97% at which point everything become extremely slow or completely non-responsive. we reboot the server, the RAM utilization goes down to about 28% but then starts
increasing again. I used Resource Monitor and looked at the memory section. From the processes listed there it looks like the sqlserver.exe process's private memory usage keeps increasing proportionally to the whole RAM utilization while the other
processes seem to be relatively constant. Here is a sample data:
August 1st: 44% used physical memory, SQL Server private memory:4.2GB
August 5th: 63% used physical memory, SQL Server private memory:8.6GB
August 9th: 74% used physical memory, SQL Server private memory:12.1GB
August 12th: 78% used physical memory, SQL Server private memory:13.7GB
Could you please suggest any tools or techniques that would help us determine what is causing this increase in RAM utilization?
thanks,

For single instance SQL 2008 R2 or higher installations where no other applications (like SharePoint) are running, it is not necessary to set MAXMEM.

How to monitor phyisical memory utilization

Can anyone let me know how to monitor the physical memory utilization using monitors/rules?
The existing monitor which is there in windows server management pack monitors the virtual memory where as i wanted to monitor physical memory

You have to create the monitor yourself.
This monitor is called a Static threshold performance monitor. In the counter list, choose % commited bytes

How can I gradually increase volume from lower freq to higher freq

I did a search and did not find anything specific to this.....i found a post on how to do this from start to end of a file......but I want to do a gradual increase starting at the lower frequencies then dropping off towards the higher frequencies or vice versa....can anyone shed any light?

If you want to change the frequency response throughout either the file, or a section of it, you have to use EQ, and the easiest way to do this is to apply it in the Multitrack view. This would mean that you could use the automation system to vary paramaters whilst the track is playing. If you don't do it this way, you'll only be able to apply a preset value to whatever selection you've made (or the whole file, if you didn't make one).
But you don't want to use pitch bending or shifting!

WAP4410N Memory Utilization Reporting 100%

My network management platform flags the WAP4410N as continuously reporting 100% memory utilization. I updated to the latest code(V2.0.4.2, but the problem persists. I confirmed with the software vendor that the MIB is actually reporting 100% utilization. Has anyone else seen this symptom?

Paul,
I haven't seen any case within the support center reporting high memory utilization consistently. If you are experiencing problems with 4410 then i would give the SBSC @ 1-866-606-1866 a call. If no problem persist then it's probably just a spike at which time all units will generally spike occasionally at 100%

How to change the max number of member display in Target Group

Dear Experts,
We are using 2007 CRM Marketing.
When I search and open a Target Group it displays me maximum of 100 entries of members over 11 pages. how do I increase or decrease the max number.
Appricate you help.
Thanks,
Shabbir Hussain

Hi,
you can set the number of members that will be displayed in target group.
Go to any profile group -> open the graphical modelling -> open settings.
Here you can ajust the displayed number of members in a targetgroup.
These settings are user-dependent and saved in table CRMD_MKTTG_PERS.

Claudia

Ancient RHEL3 Running Oracle Rac 10G - memory utilization question

As all good things must happen the crappy old systems that never get upgraded come back to bite you.
I have a 4 node RAC cluster running Linux RHEL3. I know .. would love to upgrade it .. but that will take time. Looking for at survival at this point. The system is experiencing High I/O wait. Now, my background is mainly Solaris/AIX and not Linux. So as I work through this problem I am unsure of what I am seeing, since Linux maybe handling memory differently on this OS.
This is what I am seeing:
High I/O wait as shown by TOP
Disk Access Time and Utilization : pretty good .. no device utilized over 30% and <20 millisecond response times from the drives
The real Question is in memory usage:
Host: 32GB
OS: Red Hat Enterprise Linux AS release 3 (Taroon Update 9)
model name : AMD Opteron (tm) Processor 880
Please .. I know its old but try and not laugh.......
The box has 32GB of Memory and I am told by the DBAs that OEM is reporting that SGA is sized correctly and memory ISN"T the problem. But disk access time/utilization isn't really pointing to a particular problem with the OS. The disks are all provided by a SAN.
However, when I look at TOP .. I see that the largest oracle process in RSS size is 8G .. now on all other platforms .. AIX/Solaris when using TOP .. all oracle processes that connect to the SGA will show the full size of SGA. So this is my question. Does Linux do this differently... for the DBAs to tell me SGA is set to 20GB and to only see top showing process with 8GB .. this has me confused. Is the SGA really being set to 20GB????
I can see in a pmap <oracle process> that it appears to be attached but just wanting to rule out a simple Oracle / Linux configuration problem first.
I've included a pmap of both a current Linux process on the troubled system and a pmap of a current oracle solaris host.

I have a 4 node RAC cluster running Linux RHEL3. I know .. would love to upgrade it .. but that will take time. Looking for at survival at this point. The system is experiencing High I/O wait. How/why do you relate this to a memory problem that needs memory utilisation analysed?
It could be that you have a dual fibre via HBA to the SAN and that one port is faulty (e.g. bad cable), thus reducing your I/O to the SAN to a single I/O path.
It could be caused by hotspots on a LUN - and likely because ASM is not being used, this hotspot cannot be automatically load balanced.
Or it could be a number of other factors, such as poorly designed and written app code that performs multiple passes through the same data sets, abuse of PQ slaves, etc.
How does your storage layer look? What do you use for SAN connectivity? What diver s/w is used? How are the LUNs used (cooked/raw)? Is ASM used? What does Oracle session and instance reports ito I/O wait times? Which datafiles are being hit the hardest? Is acrhive logging used and what is the frequency of log switches? Etc. etc.
Memory utilisation does not impact I/O, unless it is swap I/O. And these symptoms are easily seen and easily diagnosed. So I would expect that high memory utilisation may be a symptom, as is I/O wait times, of a potential underlying problem. But it would be premature to blame one (e.g. I/O wait times) on the other (e.g. memory utilisation).

How do i change ringtone volume to ring with low volume first and then gradually increase to the max volume ?

how do i change ringtone volume to ring with low volume first and then gradually increase to the max volume ? this feature was available before but is still available now ? this is for IOS8 running on Iphone 5c.

I've never been aware of a function like this in the past. You could create a personal ringtone that would last 30 seconds or less and set the volume on that ringtone to do that with an audio editor, such as Audacity.

How to get the Memory Utilization Data for Cloud Service

Hi,
We are planning to monitor the Performance of Cloud Services hosted onto Azure through VisualStudioOnline [TFS]. However, I couldn't find any performance metric for Memory utilization on individual Cloud Service.
So please help how can we monitor Memory utilization on individual Cloud Service hosted through VSO.
Thanks.
Regards,
Subhash Konduru

XML Parser and memory utilization

I am using the sample given with
the PL/SQL Parser to transform a
1.5M file. When the document is
parsed Oracle's memory resources
increase 50M until the system
runs out of virtual memory and
errors out. If I decrease the
size of the file to ~750K it
works ok. When I use Saxon to
transform the file it uses ~10M.
Is there anyway to get the Oracle
parser to better utilize memory,
or am I missing some point?

Hi,
I have checked the lib folder. xmlparsev2.jar is there. Is this the classpath? if not how do i get it to the classpath? and how do i do that?
Thanks for your help so far

Agent resident memory utilization ALERT question

Hi all,
Every night during the incremental db backups (and during the weekly full db backup) i get an alert for the "Agent resident memory utilization" level. I did find this similiar post but it didnt' help me out much (Agent memory utilization under Linux
I want to know if i should be concerned with this alert and how i can tune to get rid of it. Does anyone know how to handle this?? I found the following in the oracle documentation about this alert:
1 Agent
The oracle_emd target is a representation of the Oracle Management Agent. The Oracle Management Agent is the Management Agent used by Oracle Enterprise Manager. This target type exposes useful information required to monitor the performance of the Management Agent.
Most of the help topics in this helpset use the term Management Agent to refer to the Oracle Management Agent.
1.1 Agent Process Statistics
The EMD Process Statistics provides information about the performance and resource consumption of the Management Agent process. This metric is collected by default on an interval of 1038 seconds. A value that can be changed in the default collection for the oracle_emd target.
1.1.1 Agent Resident Memory Utilization (KB)
The amount of resident memory used by the agent and all of its child processes in KB.
I also get nightly alert for Commit waits but i don't think they are related. Can someone please shed some light on this alert for me? Here is the full alert that i'm getting:
Name=localhost.localdomain:3938
Type=Agent
Host=localhost.localdomain
Metric=Resident Memory Utilization (KB)
Timestamp=Sep 13, 2006 2:08:14 AM EDT
Severity=Warning
Message=Agent resident memory utilization in KB is 223304
Rule Name=Agents Unreachable
Rule Owner=SYSMAN

If your Agent is really getting up to the Warning or Critical Threshold set for the agent resident memory utilization" metric, you can increase the numbers. by default, the Agent "Resident Memory Utilization (%) is set to 20% (Warning) and 30%(Critical) while "Resident Memory Utilization (KB) is 128000 (Warning) and 256000 (Critical)
From Targets > All Targets > Select the Agent > Click Metric and Policy Settings at the bottom of the screen > Edit the Resident Memory Utilization as required.
Or Instead changing the Threshold, on the same Edit screen, you can simply change the "Number of Occurrences" before an alert is triggered.
Meanwhile it is important to check whether the use of such amount is normal.

Memory utilization alway at 100%

I frequently receive alerts via EM 12c that I have reached near 100% of my memory for my host servers. My servers have lots of RAM and have been running fine for a long time. I have tried to increase the metrics so it does not warn me until it hits 99.5% but it still sends me alerts. I am not sure what I have to configure differently for EM to not think this is a problem.
Thanks
Andy

Just to clarify a few things. My oracle databases instances are running on an 2 HPUX server. Enterprise Manger consistently shows that the Memory uitilization is near 100%, it never really drops it just stays flat lined at near 100% and every once and a while their will be a spike where it will drop to 90 or 95%. I am letting AMM auto tune the memory between PGA and SGA. I only have agents running on HPUX for Enterprise Manager.
I have Enterprise Manager 12.1.0.1 setup on a Windows 2008 R2 server. I have only had EM setup for a few months but I beleive the issue of memory showing near 100% is an old issue. Again the environment and the servers are working fine.
After doing a bit more research to me the real problem is how enterprise manager looks at the memory. If I use an utility such as a tool that comes with HPUX called "Glance" it shows the following. I have 32 GB or Physical memory, System is using 7.5 GB of this memory and User is using 10.7GB and their is 15.1 GB of free memory. So the "Glance" utility shows my memory utilization is just fine.
FYI memory is also showed to be healthy when looking at it with the below command.
# swapinfo -m
Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 34816 0 34816 0% 0 - 1 /dev/vg00/lvol2
dev 34816 35 34781 0% 0 - 0 /dev/vg02/lvolsw1
reserve - 6626 -6626
memory 31147 14588 16559 47%
To me it seems to me that Enterprise Manager is adding up the System Memory + User Memory + Free Memory and comparing it to the Physical Memory. When it should be taking only System Memory + User Memory and comparing it to Physcial memory. So the metrics it is looking at need to be modified somehow.
