Best practice for CPU and memory usage?

I find my AIR application takes a lot of memory -- usually
>170M. And what is strange is that the memory usage is
increasing (about 4K/s) even when the application is simply sitting
there and do nothing. The CPU usage is supposed to be 0% when the
application is doing nothing, but it's not (usually ~5%). So I
wonder if there is any article about best practice on CPU/Memory
usage.

Those numbers indicate that your application is in fact doing
something. Perhaps you have a timer still running, or work being
done on an enterFrame event?

Firefox keeps freezing and using 50% cpu and memory usage shoots up most of the time it's when there's an auto update of anything addon, plugin or ff!

Firefox keeps freezing and using 50% cpu and memory usage shoots up real fast and carries on going till it uses up all there is left. Most of the time it's when there's an auto update of anything addon, plugin or ff but not just neccessarily then! I find out it's happened when there's been an update after i restart and an extra webpage comes up with the particular addon/plugin/ff update. I have to restart most of time because nothing sorts it out. I'm using windows xp with the latest update of ff 13.0.1 it's not this version because it's been happening for a while. And it never started when i added a particular addon or plugin or when i added a new app to my pc either. Any idea as to what this may be or how i'd sort it out?
Cheers

Get CPU and memory usage

Hi!
I would like to know if there is any way of getting system CPU and memory usage using Java code.

I want to get the system CPU and memory usage using the performance monitor dll, the perfctrs.dll, but access this data using Java language.Then you should create wrapper dll between your java code and perfctrs.dll and convert data from format of dll to format of your java code.
So, that is next question - how to create wrapper dll, how to deal with or how perfctrs.dll works?

Best practice for Plan and actual data

Hello, what is the best practice for Plan and actual data? should they both be in the same app or different?
Thanks.

Hi Zack,
It will be easier for you to maintain the data in a single application. Every application needs to have the category dimension, mandatorily. So, you can use this dimension to maintain the actual and plan data.
Hope this helps.

DNS best practices for hub and spoke AD Architecture?

I have an Active Directory Forest with a forest root such as joe.co and the root domain of the same name, and root DNS servers (Domain Controllers) dns1.joe.co and dns2.joe.co
I have child domains with names in the form region1.joe.com, region2.joe.co and so on, with dns servers dns1.region1.joe.co and so on.
Each region has distribute offices that may have a DC in them, servers named in the form dns1branch1.region1.joe.co
Over all my DNS tests out okay, but I want to get the general guidelines for setting up new DCs correct.
Configuration:
Root DC/DNS server dns1.joe.co adapter settings points DNS to itself, then two other root domain DNS/DCs dns2.joe.co and dns3.joe.co.
The other root domain DNS/DCs adapter settings point to root server dns1.joe.co and then to itself dns2.joe.co, and then 127.0.0.1
The regional domains have a root dns server dns1.region1.joe.co with adapter that that points to root server dns1.joe.co then to itself.
The additional region domain DNS/DCs adapter settings point to dns1.region1.joe.co then to itself then to dn1.joe.co
What would you do to correct this topology (and settings) or improve it?
Thanks in advance
just david

Hi,
According to your description, my understanding is that you need suggestion about your DNS topology.
In theory, there is no obvious problem. Except for the namespace and server plaining for DNS, zone is also needed to consideration. If you place DNS server on each domain and subdomain, confirm that if the traffic browsed by DNS will affect the network performance.
Besides, fault tolerance and security are also necessary.
We usually recommend that:
DC with DNS should point to another DNS server as primary and itself as secondary or tertiary. It should not point to self as primary due to various DNS islanding and performance issues that can occur. And when referencing a DNS server on itself, a DNS client
should always use a loopback address and not a real IP address. detailed information you may reference:
What is Microsoft's best practice for where and how many DNS servers exist? What about for configuring DNS client settings on DC’s and members?

Local Director SNMP for CPU and Memory

Is there any way to get the CPU and memory utilization from a Local Director using SNMP? When I do an SNMP walk, I don't see any objects for CPU and memory.
Thank you

There's a "Show cpu " commmand availabe. Type help or '?' for a list of available commands.

SNMP OID for CPU and Memory Utilization on a MDS 9509

Does anyone know what the OIDs are for CPU and Memory utilization on a MDS 9509?
Thanks

CISCO-SYSTEM-EXT-MIB.my is a good place to start and you can determine the OID from the MIB.
Once you feel as though you are on the right track, have a look at:
http://www.oidview.com/mibs/9/CISCO-SYSTEM-EXT-MIB.html
I gather that what you need is:
1.3.6.1.4.1.9.9.305.1.1.1
and
1.3.6.1.4.1.9.9.305.1.1.2
Enjoy.

How to find out CPU and memory usage for an instance?

Hi DBA Gurus,
How to find out CPU usage and memory usage for an instance?
Any information is appreciated!
Thank you!
Robert

you can calculate cpu usage by adding fallowing three factors which you can get from v$sysstat
1. Parse CPU time : This represents the percentage of CPU time spent parsing SQL statements. Parse time CPU can be a strong indication that an application has not been well tuned. High parse time CPU usually indicates that the application may be spending too much time opening and closing cursors or is not using bind variables.
2. Recursive CPU time : Sometimes, to execute a SQL statement issued by a user, the Oracle Server must issue additional statements. Such statements are called recursive calls or recursive SQL statements. For example, if you insert a row into a table that does not have enough space to hold that row, the Oracle Server makes recursive calls to allocate the space dynamically if dictionary managed tablespaces are being used.
Recursive calls are also generated due to the inavailability of dictionary info in the dictionary cache, firing of database triggers, execution of DDL, execution of SQL within PL/SQL blocks, functions or stored procedures and enforcement of referential integrity constraints
3. Other CPU time : This represents the percentage of time spent looking for buffers, fetching rows or index keys, etc. Generally, \"Other\" CPU should represent the highest percentage of CPU time out of the total CPU time used.
total memory used you can calculate adding
total_agrigate_area+sga
memory usage on os level you can know by fallowing commands
vmstat 5 20 depending upon os

Slow slow slow...even with low CPU and memory usage.

Sometimes my Mac gets really slow, especially with applications, and even more especially when opening applications. What I don't understand is that when I check Activity Monitor during slow times, it shows plenty of CPU and memory still free, far from being maxed out. I try to keep a good chunk of my hard drive available for virtual memory too, so I'm unsure where its getting bogged down.
Any ideas?

You may just need a little maintenance:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard. These utilities have limited or no functionality with Snow Leopard and should not be installed.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc. Other utilities are also available such as Onyx, Leopard or Snow Leopard Cache Cleaner, CockTail, and Xupport, for example.
For emergency repairs install the freeware utility Applejack (not compatible with Snow Leopard.) If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard. AppleJack is not compatible with Snow Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. Tri-Backup (Commercial)
