Database slowing down
Dear buddies,
Developers around me are telling me that the database is slow (They are using PL/SQL Developer and other tools).
How should I check if the database is the one really causing the problem?
Thanks in advance.

I am not sure why CKPT has mentioned listener's response time since once the connection is estabilished, listener is no more in the picture but probably he is guessing about the connection establishment taking time so that's why he suggested it. Anyways, there is no way toget it as long as you won't enable the tracing for the listener. That should tell you about the listener's activity. But I would rather not check it but would take a statspack/awr report and will see what comes from there.

Database slow down happeing for aperticular window
Hi,
For last few days we are having a issue with database slow down for a perticular window .We took the awr and ash report for that window and it shows the db file sequential read takes more time for aperticular query.But the same query works fine for rest of the day, so how we find the issue happend at that perticular window?
ThanksHi ,
there is not a single query running for that window, multiple sessions are running which are exceuting various queries.
Here is the AWR report for that window( due to size i could past only first half of thw awr report)

We have created a stage schema and tested application which is working fine when we are moving it to another schema for further testing ( This schema is created using same scripts which were used to create objects in staging schema) the performanc of application (Developed in .NET) slows down drastically
Some of the store procedures we have checked at Databse/SQLdeveloper level are giving almost same performance but at Application level there is lot of difference
Can you please help
We are using Oracke 11g DatabaseAre you using the Database Cloud Service? You cannot create schemas in the Database Cloud Service, which makes me think you are not. This forum is only for the Database Cloud Service.

I have completed a project which automates the procesing of stock monitoring and billing ofacocacola stockist in my home town. The processor need in the machine is P4. I used JDK 1.4 with MS-Access (Office 2000) as backend. I have come across a problem which cannot be detected by me and the service engineers of system also. The problem is stated below.
(i) When i use the billing module of the project i cannot use the billing screen continuously more than 10 times. I am in need of reloading the software to start again.
(ii) All the modules get slow down when in use the software more than 45 minutes.
(iii) When the billing screen get slow an exception is thrown. The name of the exceptio is Event despatch thread queue exception.
I get this proplem when i use the part of the software which are connected to the database.
If i use the other parts of the software (non database activities)then there is no problem in using the software.
I used the same processing for a textile industry's stock monitoring system. There is no problem with the software.
Is there any timeout value set for the access database's connection or for the swing components.
Please consider my request and give suggestion as soon as possible.Hi,
I think you try to establish many Connections to the Database, but you don`t close them. This can cause memory problems and the other thing is that your database has a limited number of possible open connections. So there are two ways to solve the problem:
(1) After using the Database, close the connection immediately in a finally block
(2) Reuse one (or more) open connections. This is also known as connection Pooling. The advantage of this solution is that the performance of your application will be better because the process of establishing a JDBC Connection has high cost !

We have a report that used to produce a 1000+ page pdf in
about 2 minutes. It has gone to producing a 200+ page report in
about the same amount of time. No change to the data, database,
report or environment, it just suddenly slowed down and nothing
seems to be able to make it go back to decent performance on large
record sets.
Server reboots don't help, any ideas or thoughts would be
appreciated.Hello
I followed some Donald's suggestion and went through some explanations he's given on its web site to try to figure out how could I speed up the database 10g since we migrated from 8i to 10g.
Here are default values in our 10g influencing the COST BASE OPTIMIZER
OPTIMIZER_FEATURES_ENABLE=10.2.0.1
OPTIMIZER_MODE=ALL_ROWS
OPTIMIZER_INDEX_COST_ADJ=100
I launched his script below provided to see time waited between full scan table
('db file scattered read representing by the c3 row and the
sequential read representing by the c4 row)
select
sum(a.time_waited_micro)/sum(a.total_waits)/1000000 c1,
sum(b.time_waited_micro)/sum(b.total_waits)/1000000 c2,
sum(a.total_waits) /
sum(a.total_waits + b.total_waits)
) * 100 c3,
sum(b.total_waits) /
sum(a.total_waits + b.total_waits)
) * 100 c4,
sum(b.time_waited_micro)/sum(b.total_waits))/
(sum(a.time_waited_micro)/sum(a.total_waits)
) * 100 c5
from
dba_hist_system_event a,
dba_hist_system_event b
where
a.snap_id = b.snap_id
and
a.event_name = 'db file scattered read'
and
b.event_name = 'db file sequential read';
there is the output of the script
C1 C2 C3 C4 C5
.002438964 .002888595 24.6526611 75.3473389 118.435332
So the time waited for full scan(c3) table is most faster than index sequential read(c4:index probe)
I changed the parameter OPTIMIZER_INDEX_COST_ADJ and OPTIMIZER_MODE
alter system set OPTIMIZER_INDEX_COST_ADJ=20 scope=both;
alter system set OPTIMIZER_MODE=FIRST_ROWS_1000 scope=both;
I lauched aigain the script above, but the output shows the result below
C1 C2 C3 C4 C5
.002438964 .002888595 24.6526611 75.3473389 118.435332
this output isn't different than the first one, so does this mean that INDEXES are not well designed or WHAT ELSE?.
Wich parameter could I enable or change to decrease the C4(index sequential read wait time?
Thank you for your help -
Hi Everyone. I have an old Mac Book with software updated to 10.6.8. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive? Pls.help. Tks.
Depending on which email client software you use
the files should be in 'your home folder' library, esp.
if you use Mail application.... ~/Library/Mail
Since you don't specify what mail application,
that would most be associated with the file.
I notice there are some items to the right of your post
where it says "more like this' so that may be worth a
look to see if similar issues were answered. Also, the
Help viewer in your system is a searchable database.
Seems that google also brings up fair information, too.
Do you have a complete bootable clone of your entire
Mac system on an externally enclosed hard disk drive?
Good luck & happy computing! -
System slowed down after Mavericks update (10GB RAM)
Hi,
I have recently updated to Maverics on my mac pro, 2 x 2.8 GHz Quad-Core Intel Xeon, 10GB RAM.
When I perform regular tasks it's all normal. Unfortunately I do some much more than that. I use Aperture on a daily basis and it seems to have slowed down a bit. The issue is more apparent when I use Final Cut. I can't have any other design/photography/video software on the background anymore. My computer can't deal with. But it could before Mavericks! It will also complain about not enough memory when rendering...
I understand that kernel task is heavy on the memory and after an EtreCheck I also realised how much memory spotilight is using. I already excluded a lot of items from spotlight, and it's way better, but still, why is my computer so slow?
Please can someone look at my check and tell me if there's anything I can do to boost my system back to it's previous glory?
thank you

About memory management in OSX 10.9 Mavericks
Memory is managed differently, and more efficiently in 10.9. It is (mostly) unique in the industry, but may become trend.
Let’s start with the basics. Mechanical disk drives are very slow, with access speeds in the 10s of milliseconds and transfer rates in the 200-400 Mbps range real world. SSDs are much faster, on the order of a couple of ms access and typically 1200-3000 mbps transfer rates. RAM is much faster than either, in the nanosecond access and transfer speeds of ~8 Gbps effective (1 GHz x 8 bits/byte).
These are rough numbers for comparison purposes only.
So the goal is to keep as much in RAM as possible. But if you run out of RAM what do you do?
Traditionally you take the least used RAM and write it to a special part of the disk, in a way that you can access it most efficiently - minimizing the disk delays. This is called a swap file because you swap RAM in and out of it.
10.9 has a new trick: it compresses RAM using the main processors. Rather than swapping stuff to disk (disks are slow), it actually uses the processor to compress memory and make, for example, 1 GB of physical RAM hold as much as 1.5GB. Similar approaches are used to make MP3 files 10x smaller than the real thing - there is redundancy in data and you can take advantage of that. Apple is making the following calculation: the processors can compress way faster than the disk can swap. And its also predicting that the processors are often partly idle - waiting for swap files or disk access. So rather than swap files around, its compresses the files ***in RAM***.
Compression works,. Tests show that on average it is faster, and that 4GB (i have 4 GB RAM) acts like 5 1/2 - 6GB. Wow.
So, 10.9 will load up most of your RAM, knowing that it can compress some when it needs to. So don’t worry too much that it may look like all your RAM is taken - yea, it is, but its OK.
The measures to look at are:
1. amount compressed. Compression means it has run out of RAM and needs more. As long as compression is low this is fine. In fact this is how 10.9 uses RAM more efficiently than 10.6,7 or 8. Contrary to common wisdom, it requires LESS RAM than 10.8. The colored indicator tells you who this is going - green (good), yellow( iffy) and red (bad).
2. amount swapped. Once it cannot compress any further, or can’t do so efficiently, jot begins old-fashioned swapping. This is a major slow-down and means you would benefit from more RAM. Tiny amounts are OK.
here's an article by Apple - but on th pre-10.9 memory management techniques....mostly still true, but read on.
http://support.apple.com/kb/HT1342?viewlocale=en_US
Bottom line - compression makes 10.9 use RAM more efficiently than previous OSX versions. It also makes the “ram used” indicator less meaningful, and mans you should monitor “compression” .
That said, RAM has always been one of the most cost effective upgrades possible. People spend too much on new machines and too little on more RAM.
Hope this helps,

LR 2.5 slows down after upgrading to Snow Leopard
This is my first post, so first of all I'd like to say hello to everybody here and apologize for my poor english
My computer is an iMAC with an Intel Core 2 Duo, 4GB RAM, 500GB HD and a graphic card NVIDIA GeForce 8800 GS with 512 MB VRAM.
The LR database is contains, up to now, about 5000 photos most of them in NEF format (my camera is a Nikon D300)
In the last month I noticed that the performance slowed down consistently as thumbnails refresh started taking a long time as well as editing photos and the overall LR2 (executing at 64bits) working.
I started monitoring the system, but despite the low LR2 performances I still had a lot of free RAM and the cores weren't really working a lot.
I can't say this for sure, but I could bet that the performance problems began with the upgrade to Snow Leopard.
Can anybody help me to solve this issue?
Thanks a lot in advance

Lightroom performance should not have deteriorated as a result of upgrading to Snow Leopard. Things that you should check are:
1. that you are indeed running Lightroom in 64-bit mode (open System info under Help menu and check that Application Architecture shows x64)
2. that you have all of your previews rendered to at least Standard-size
3. that you have at least 20% free hard disk space
You should also run the Catalog Optimisation option in Catalog Settings
1. Yes, LR2 was running in 64 bit mode before upgrading to Snow Leopard, then (don't know why) gets back to 32 just after the upgrade and I manually set it to 64 bit (checked in the application and on the process monitoring while running)
2. I have the preview rendered 1:1 in the folder I'm working on (done again tonight)
3. I have 55% free HD space
4. I run a Catalog Optimization many times, The last one was tonight
In other words I've checked and tried all these things many times. I've red on the internet that it might be a geforce 8800 issue, but I've found only windows references. Don't forget that neither RAM nor CPU are stressed when LR2 is working and all other applications run normally -
My computer slows down and hangs after installing oracle 10g
My computer just slows down after installing oracle 10g. I have a pentium 4 3ghz with 512 memory (32 mb used by graphics built in card). It slows down and hanged even if I agjusted the swap memory to 800 mb. I have two swap file/page file - in drive c and drive d. I even cannot shut it down because it takes maybe 30 minutes just to see the "shut-off/log-off" screen.
Before starting up Oracle, when you go to the task manager, how much RAM does it show actually free? 512 MB is pretty small to run Oracle in the first place-- Windows and Office can use a fair chunk of RAM themselves, depending on which Office apps you are running. You may also be suprised by the amount of RAM that a web browser, email client, and the various other apps that folks generally install can use.

Yes it's another Mavericks slowing down my laptop thread :)
Hi there
I recently installed Mavericks, just before Xmas in fact, and noticed how slow it was from the start. Now I'm back at work, it's killing me!
First off, I had lots of problems with Mail, and something to do with Keychain (forgive me, laptop is a tool, I don't really understand how it works). I managed to get that working, although, I must say it still is slow at collecting mail from my various accounts.
Word, well that's just hysterical. I can sit and type a few lines, sit back and watch Word catch up with me over a minute or so, then have to go back and correct my terrible typing, it's painful and un-usable. I have noted on here to rebuild my Office Database, which I've done, and it appeared to have no problems.
So what to do? I heard about EtreCheck so have run that and will paste results below, I'm hoping that someone will spot something there that is really obvious and return me to fact Mac nirvana.
I'm on a 2011 MacBook Pro, 2.8ghz Intel Core i7, 4GB RAM. i don't have lots of 3rd party stuff installed, but do run Photoshop, Quark, Office and a few other apps.
Here's hoping for help, and thanks in advance!

Outlook 2010 - User tends to open many emails at a go but this may slow down the machine.
Hi,
My user tends to have this work habit of opening 8-10 emails at one go. She view this way of working as more efficient and faster. But this means that if outlook crashed, all the emails will be close as well, and this way of working tends to slow down the
machine.
Is there any way Outlook can users to open multiple emails without hording CPU page milage?
Thank you.Hi Josh,
Slow Outlook can be also harmful for your database and there are numbers of factor which slow down the MS-Outlook like:
* Third Party Plug-ins
* Slow internet connection
* Antivirus/ Firewall Programs
* Corruption or Error within Outlook
So always try to open Microsoft Outlook in safe mode whenever you stuck in such problems.
How to optimize Outlook performance:
* By Disabling add-ins
* Check default account settings
* Disabling Scanning programs
* Scanpst.exe (Inbox Repair Tool)
For more brief about Outlook disturbance and solutions:

Please,
I have just migrated a database from one server to another powerful server, but the issue is that one of the sql statement is very very slowing down.
we downloaded the dump file to another server, and the same sql is very very fast.
I shrank/rebuilt , table/indexes but no changes found, I also created new indexes that show up into the excution plan,but nothing changed.
My Question:
There is another area where I could look at to tune this sql statment?
ThanksYou may need to consider two things here.
1. Make sure you keep the parameter optimizer_mode consistent between two databases? If not, you may experience performance degradation. Some legacy third-party application may still run upon RBO. That's what we ever experienced.
2. It's time to gather statistics. See below.
When to gather statistics:
Candidates
– After large amounts of data change (loads, purges, bulk
updates)
– New high/low values for keys generated
– Newly created tables
– Upgrading CPUs, I/O subsystem (system statistics)
– RBO to CBO migrations
– New database creations

Hi All,
I m using oc4j 10g and it slows down in 24 hrs and then i need to restart it.
Following are the configurations.
1- Web Serever : oc4j 10g running on server machine.
2- OS: Windows 2003
1- Database : Sql Server 2000 running on different server machine.
2-OS : Windows 2003
The application is used in Call Center as well as by branches.
The java.exe size reaches around 65 mb until i have set the xms parameters in start.bat file and now java.exe size shoots up to around 900 mb with random behavior.There is no congestion at database level.
Your quick response in this regard would be highly appreciated
Thanks in advanceChecking the connection pool configuration to make sure you have the proper max-connections and min-connections setting in data-sources.xml if your application accesses database. Also check the thread pool configuration in server.xml. And check the GC.

Why did Mavericks slow down my MBP?
Did some digging in Discussions and found that a slow-down problem is common after installing Mavericks.
EtreCheck was recommended as a diagnostic first step. I have a report but I am not confident to act on any items without advice. Here it is - help appreciated.

Anything in Startup Items could be a problem. Apple declared Startup Items to be obsolete in 2006 so this is software that hasn't been updated since before then or they are following the doing the don't-update-until-it-breaks plan.
I suggest uninstalling these problems to see if that fixes things. Always use the vendor-provided uninstaller or uninstallation instructions. Never try to do it manually. That could only make things worse. You may need to download a new installer that may come with an uninstaller. Unfortunately, installers, and especially uninstallers, are a weak point of OS X compared to Windows.

Remove these too. iStat seems to have an invalid plist file. KeyAccess has a support link that may eventually lead you to an uninstaller.

Notice a trend? This is why I say to use vendor-provided uninstallers.

Some of the same software is here. At least with Login Items, you can remove items very easily and put them back later if they prove innocent. -
Query slows down after second run for Index Organised Tables
We are trying to optimise our application which supports MSSQL to run with Oracle 9i for one of our customers.
We have created one database with normal tables and PK constraints/indexes and turned caching on for the tables, this seems to work well but no way as fast as MSSQL on similar hardware. The first run of query was slower but as the caching became more effective the query times came down.
So we investigated turning the tables into Index Organised Tables. We ran analyze on the new indexed tables and the response time of one of our more complex queries became akin to MSSQL. We ran the same query 5 seconds later and it took about 3 times longer to return the same data. Subsequent runs produced the same result.
We have run the same query on both styles of tables and also run showplans on the two queries, the regular table returns a cost of 190 and the IOT 340. This would point to the fact that we should use the regular tables for our queries but why did the IOT set return much faster for the first run after the analyze then slow down as if the stats were missing, but the execution plan remain the same.
Any help would be appreiciated.
Darren Fitzgibboncould be a lot of reasons:
1. Is Oracle the only process that runs on this server? Could it be any other process (i.e. MSSQL) that took the the resources during the secodn run?
2. Is this the only query that was running during your tests? Could there be another query that put the load on the database when you were running the second test?
3. The autotrace statistics and explain plan would be useful for first and second run
(how to use autotrace:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96533/autotrac.htm#1018
4. If you run the same process again several times - how does the response time change?
