Slow respone on xenon server
we have an application on oracle 8i database with devloper/2000 as client
we migrated our database on xenon server with 2 gb RAM from pentium iii server.
everything as running fine except one query has incresed the respone time which was fine earlier on prevous server.
what causing the problem could any body help please/
thanks in anticipation.
There is too less data known to give an advise.
- Which operating system do you use?
- What version of Oracle do you use?
- How´s your SGA/PGA configured on those machines?
and many more questions... please be more specific...

Why index creation is slower on the new server?
Hi there,
Here is a bit of background/env info:
Existing prod server (physical): Oracle 10gR2 10.2.0.5.8 on ASM
RAM: 96GB
CPUs: 8
RHEL 5.8 64bit
Database size around 2TB
New server:
VMWare VM with Oracle 10gR2 10.2.0.5.8 on ASM
RAM 128GB
vCPUs: 16
RHEL 5.8 64bit
Copy of prod DB (from above server) - all init param are the same
I noticed that Index creation is slower on this server. I ran following query:
SELECT name c1, cnt c2, DECODE (total, 0, 0, ROUND (cnt * 100 / total)) c3
FROM (SELECT name, VALUE cnt, (SUM (VALUE) OVER ()) total
FROM v$sysstat
WHERE name LIKE 'workarea exec%')
C1
C2
C3
workarea executions - optimal
100427285
100
workarea executions - onepass
2427
0
workarea executions - multipass
0
0
Following bitmap index takes around 40mins in prod server while it takes around 2Hrs on the VM.
CREATE BITMAP INDEX MY_IDX ON
MY_HIST(PROD_YN) TABLESPACE TS_IDX PCTFREE 10
STORAGE(INITIAL 12582912 NEXT 12582912 PCTINCREASE 0 ) NOLOGGING
This index is created during a batch-process and the dev team is complaining of slowness of the batch on new server. I have found this one statement responsible for some of the grief. There may be more and I am investigating.
I know that adding "parallel" option may speedup but I want find out why is it slow on the new server.
I tried creating a simple index on a large table and it took 2min in prod and 3.5min on this VM. So I guess index creation is slower on this VM in general. DMLs (select/insert/delete/update) seem to work with better elapsed time.
Any clues what might be causing this slowness in index creation?
Best regardsI have been told that the SAN in use by the VM has capacity of 10K IOPS. Not sure of this info helps. I don't know more than this about the storage.
What else do I need to find out? Please let me know - I'll check with my Sys Admin and update the thread.

Slow respon when update Document Numbering
Hi Expert,
We have 7 branch and 4 different type of sales document. and we change our document numbering every month.
We have use SAP Business One for a year. So, we have large number of document numbering.
when we update and add new row in document numbering, we get slow respon. It can about 30 minutes every update.
how can we make it faster?
*we use 8.82 PL:08 version.
Regards,
Triadi BagusHi Triadi,
Try to update Document Numbering when no user are logged on data or Ask your users to not to post any transaction during the period when you are updating Document Numbering.
This problem arise because when user are punching transactions on database as Internal Document No Changes every time a transaction is punched on Database.
This May be the reason.
Hope this help!!

My Adobe Muse website wont publish, it's running slow and showing a server error
I've had a website in adobe muse that I've published many times before with no errors. After publishing, It tries to upload the site and loads it very slow and stops at about 69% and says the server is not connected, even though I have internet, checked the firewall and updated the cache in explorer. I was able to upload another website that I have on Muse, it loaded slowly also, stopped at 97%, I resumed it and it loaded. What to do next?
The site is hosted through business catalyst: northstarconservancy.org. I've had no issues with this website in three years and have been able to edit and publish with no problems. It shows a server error and says to check my network connection. I noticed that adobe was working on their server the night before I had this issue, so I will probably have to call the tech support and see whats up with it, since it seems related. Thanks, Amanda

Slow browsing on windows server
I upgraded 4 stations that were running under Tiger to Lion and now the browsing of my Windows server via the Finder is awfully slow. I've a read a number of so-called fixex whcih none seems to work for everyone.
Is the problem only with files from the server?
Do downloads from the internet go any faster?

It's very slow to access file server after installed SP1 of Win7.
I found it's become very slow to access shared files on file server after installed win7 SP1, (windows6.1-KB976932-X86.exe), access same file, the win7 without sp1 is fast in 5 secs, but the pc with sp1 need more than 30 secs. And
I tried to removed the sp1, everything goes fine, access fast as others.
I don't understand what's the reason and which feature affected it, I believe the sp1 can help Win7 be more safety, but why the performance on it get worse.
And I didn't find the same question or tips on forum or website, do you really haven't the issue?

Slow Files Copy File Server DFS Namespace
I have two file servers running on VM both servers are on different physical servers.
Both connect with dfs namespace.
The problem part is both servers never have same copy speed.
Sometime very slow files copy about 1MBps on FS01 and fast copy 12MBps on FS02.
Sometime fast on FS01 and slow on FS02.
Sometime both of them slow..
So as usual I reboot the servers. Doesn't work.
Then I reboot the DC01 also doesn't work. There is another brother DC02.
After I reboot DC02, one of the FS become normal and another FS still slow.
FS01 and FS02 randomly. They never get faster speed together.
Users never complain slow FS because 1MBps is acceptable for them to open word excel etc.,.
The HUGE problem is I don't have backup when the slow FS days.
The problem since two weeks I'm giving up fixing it myself and need help from you expert guys.
Thanks!
DC01, DC02, FS01, FS02 (Win 2012 and All VMs)Hi,
Since the slow copy is also occurred when you tried the direct copy from both shared folder, you could enable the disk write cache on the destination server to check the results.

Slow RD connection to server via RD Gatway if NLA is disabled on the server
If I disable NLA on a server (tried on 2 different servers), the rd connection (via gateway only) is much slower (over 1 min to get to the logon screen).
RD Gateways are 2012R2, hosts are 2012 and 2012 R2.
Re-enabling NLA fixes the issue. Any ideas?
Dario PalermoHi Dario,
Putting the gatewayusagemethod:i:1 in the .rdp file will force the RD Client to use the gateway always and thus speed up the connection time. When connecting from the Internet, as a test, please uncheck Bypass RD Gateway server for local addresses in the RD
Client options--Advanced tab--RD Gateway settings.
Please try “Require user authentication for remote connections by using Network Level Authentication” policy setting under below path.
Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Security
Configure Network Level Authentication for Remote Desktop Services Connections
https://technet.microsoft.com/en-us/library/cc732713.aspx

Hi
I am running a query as below;
INSERT INTO tblEvents( <fields list> )
SELECT <fields list>
FROM OPENROWSET('SQLNCLI', 'Server=<ip address>;DATABASE=MyDB;Uid=sa;Pwd=MyPassword;', 'SELECT * FROM tblEvents') AS a
WHERE (ID = 68596)
Problem is that below part of query runs very slow (takes around 3 mins to complete) even though it just needs to bring one row.
SELECT <fields list>
FROM OPENROWSET('SQLNCLI', 'Server=<ip address>;DATABASE=MyDB;Uid=sa;Pwd=MyPassword;', 'SELECT * FROM tblEvents') AS a
WHERE (ID = 68596)
What is the problem and how can I speed it up?
Thanks
RegardsHi,
as Ronen already mentioned, the syntax you are using will not push anything from the confition down the provider stack to the data source, it will pull the whole data and the filter it on the client side. (where you execute the query).
You can either use the syntax that Ronen already pointed out OR use a linked Server along with the existing provider for SQL Server. In most cases the provider is able to push down the conditions to the data source, have it executes here and then bring back
only the relevant rows. This depends on the query you are using and the ability of the driver to translate the conditions.

Swing app in JDK6 continues to rendering slow in Windows Terminal Server
Hi,
Because Swing apps create interfaces internally and not using default OS APIs,
when running into a Windows Terminal Server client, there is no way to optimize
rendering. Windows Terminal Server and Linux FreeNX use a mechanism to send
to client only commands to render the windows. But, because the way Swing works,
not totally integrated to OS APIs, it's not possible for terminal servers to do this,
and these servers render Swing like images, something like VNC do, very slower than.
I have tested native apps and AWT apps, and the difference is very significant,
something like 50-70% faster.
Is there some project in Swing APIs or java.net open-sources to better this?We are also seeing this issue with a Compiere implementation. With 10 distributed sites across the US, our client wanted to use Windows Terminal Services to simplify the client desktop management of the Swing application.
But performance is terrible...and screen painting issues a real problem. We are also on JDK5 still, so I'm discouraged to see that JDK6 doesn't appear to offer much improvement?
Is there any project afoot to address this issue for installations using terminal services?
Thanks,

All the three servers are using the same configuration, so, I'm afraid it's not possible to give you a simple answer. You will need more troubleshooting.
I would recommend you to start by checking the differences between the servers because one of those differences is certainly causing the failure.
Also, it would be helpful to get traffic captures on the TenGig interface of the ACE to compare the behavior of the connection when going to the different servers, as well as the differences when being load-balanced vs accessing the server directly.
If you need help with this troubleshooting, you can always open a TAC service request

SSAS Tabular slow (full) processing when server is up for more than a day
Setup: SQL 2014 CU3. Machine with 2 physical CPUs and 384GB of RAM. Windows 2012R2.
96GB allocated to SQL Server, rest allocated to Vertipaq/Tabular.
Problem: after a restart of Analysis Services (Tabular), processing time for full processing is fine. Processing of the main table runs with 145000 rows/sec for one cube, and 60000 rows/sec for the other.
After a day of uptime, full processing is slower by a factor of 2-3. For the second cube, performance stays at a low ~ 18000 rows/sec for subsequent full processing.
Performance counter says "memory Limit Vertipaq KB" ~ 280GB, "while memory usage KB" ~ 63GB. There should be plenty of free memory.
SQL Queries for the tabular data are fine and extremely simple and high performance.
I can reproduce the effect at will.
Is this a known bug?Please try to clear the cache and check if this issue is persists or not.

Hello. I have recently started to experience major slow downs on my G5 when saving to the server. The problem is really noticable when saving from a program (Photoshop, Illustrator etc) to the server - it takes 30-40 secs whereas before it would be almost instant. I've tried the exact same file on a G5 dual on the same network and server and its fine.
I've done the obvious - changed cables, rebooted, rebooted server, disconnected iDisk, switched ports. When I connect directly to a PowerBook with an ethernet cable it works fine.
Can't think of anything else - any ideas!?
G5 Quad Mac OS X (10.4.6)I'm experiencing the same issue. My situation is a PC connected to a Powerbook G4 with a single ethernet cable (100Mbit). Recently (I suspect since an OS X upgrade), the transfer rates from the powerbook to the PC have gotten very slow. If I use MenuMeters to monitor the transfer speed, I can see the speed spiking erratically, jumping up to hundreds of kilobytes and dropping back to a couple kilobytes per second, each second. When I download files to the powerbook, the speed is rock solid multiple megabytes per second.
I've tried changing the network cable, tried tweaking the network settings on the PC to no avail. The only thing that helped slightly was to change the powerbook's ethernet settings to 100Mbit half-duplex (I read on a different thread that slow upstream/fast downstream is a 'typical duplex misconfiguration issue'). Now, the transfer speed is still quite erratic, but the average speed is much higher (back in the megabyte-per-second range). But if I set it to autoconfigure, or force it to full-duplex, the speed is much slower. This is still not a real solution though.
This problem occurs regardless of protocol (I've tried SMB and FTP). Given that this has suddenly started appearing, I suspect a faulty OS upgrade. I'm certainly happy to hear that I'm not the only one with this problem.
