Oracle 10g on HP-UX, Terrible Poor Performance!!

Hi All,
I setup an Oracle 10g on HP-UX 11iv1. Server is a HP 9000, 4 CPUs (750
MHZ). It is connected to Disk System 2405 (Virtual Array 7110). Fiber
Channels are connected at 2 GB speed.
I installed a cluster 10g database. First I installed CRS and after
that I installed oracle database. ( I want to test clustered database
with one instance)
I installed every thing line by line as oracle document wrote.
All the things, kernel parameters, patches, are like oracle wrote in
its document.
I installed Golden quality package June 2004.
I increased shmmax to 2.3 G . My SGA is 1.7 G And change some other
parameters as Sandy Gruver wrote in Best Practices for Oracle on HPUX.
I used oracle new storage system called ASM for this case.
When I put the system under the load, I was monitoring the system
carefully.
I started gmp. When we sent some quarries to database (It is not heavy
load, I tested it with a Linux system on proliant ML570 without any
problem), suddenly DISK section in gpm changed to red (critical ) I
read the warning. It said "Disk bottleneck probability = 100%". I
changed the output of disk report to "Report IO by Disk"
"DISK%" was 100% and "RAW IO RT" was about 1000 for two disks ( This
two disks dedicated for ASM). In this situation CPU idle time was 1% or
2% for all the CPUs but load average was about 1. Performance is not
acceptable at all ( In comparison with Oracle that installed on Linux).
Glance reported Disk was in Critical situation.
I think the problem is IO or something about Disks
I used HP Disk System 2405. Fibber channels on both server side and
Disk Array side are configured at 2 Gb and topologies are
PTTOPT_FABRIC.
Is it ok that RAW IO RT about 1000 for each LUN?
Why Disk% in glance/report IO BY Disk/ was 100%?
I found an error in STM logs about I/O.It said:
Entry type: I/O error
Product: Fiber Channel Interface
Logger: td
It logged this error about 12 times during the test.Any comment?
Regards,
Hasan

Sorry, I have not a solution for your problem, but similar things happen on our installation on Solaris 5.8 with Oracle 10:
I have a banking business solution from Windows/SQL Server 2000 to Sun Solaris/ORACLE 10g migrated. In the test environment everything was working fine. On the production system we have very poor DB performance. About 100 times slower than SQL Server 2000!
Environment at Customer Server Side:
Hardware: SUN Fire 4 CPU's, OS: Solaris 5.8, DB Oracle 8 and 10
Data Storage: Em2
DB access thru OCCI [Environment:OBJECT, Connection Pool, Create Connection]
Depending from older applications it's necessary to run ORACLE 8 as well on the same Server. Since we have running the new solution, which is using ORACLE 10, the listener for ORACLE 8 is frequently gone (or by someone killed?). The performance of the whole ORACLE 10 Environment is very poor. As a result of my analyse I figured out that the process to create a connection to the connection pool takes up to 14 seconds. Now I am wondering if it a problem to run different ORACLE versions on the same Server? The Customer has installed/created the new ORACLE 10 DB with the same user account (oracle) as the older version. To run the new solution we have to change the ORACLE environment settings manually. All hints/suggestions to solve this problem are welcome. Thanks in advance.

Poor performance on reports that were migrated from 6i to 10g

We are migrating from 6i client server to 10g reports server and getting poor performance on various reports. Reports that work in seconds in 6i are taking much longer to run or even timing out.
Reports Server:
Version 10.1.2.0.2
initEngine = 1
maxEngine = 20
minEngine = 1
engLife = 1
engLife = 1
maxIdle = 30
The reports are being called from 10g forms with the following:
T_repstr := '../reports/rwservlet?server=rep_aporaapp_frhome1'

|| '&destype=cache'

web.show_document(T_repstr,'_blank');

Using these and not hearing much bad

Oracle 10g JVM Profiling

Want to profile Oracle 10g Database JVM to figure out performance issues while executing Java Stored Procedures. Need to know the steps to connect a profiling tool like JProfiler to Oracle 10g Database JVM. Also wanted details on Oracle JVM startup command on 10g database to mention the VM parameters to configure Profiling tools.

As a suggestion...
You might be able to find a process id.
As for the VM options try getting properties from System and printing everything in there.

On the production system we have very poor DB performanceHave you identified the cause of the poor performance is not the queries and their plans being generated by the database?
Do you know if some of the queries appear to take more time than what it used to be on old system? Did you analyze such queries to see what might be the problem?
Are you running RBO or CBO?
if stats are generated, how are they generated and how often?
Did you see what autotrace and tkprof has to tell you about problem queries (if in fact such queries have been identified)?

Oracle 10g performance is slow

Dear Exports
how we can imporve the Oracle 10g performance........we are upgrading from Oracle 8 to Oracle 10g. Windows platform. and using Oracle developer 6 as front end .
thanks in advance

Do you have statistics gathered on the tables in the 8i database? Can you post the explain plan for the query in both databases?
Since you know what SQL is having poor performance you can use TKPROF and SQL TRACE to see where your query is spending its time.
Try the following:
alter session set timed_statistics=true;
alter session set max_dump_file_size=unlimited;
alter session set tracefile_identifier='BAD_SQL';
alter session set events '10046 trace name context forever, level 12';
<insert sql with poor response time>
disconnect
Use the TKPROF utility on the file found in USER_DUMP_DEST that contains the string BAD_SQL.
For information on how to interrupt the TKPROF output, see the following link.

Non jdriver poor performance with oracle cluster

Hi,
we decided to implement batch input and went from Weblogic Jdriver to Oracle Thin 9.2.0.6.
Our system are a Weblogic 6.1 cluster and an Oracle 8.1.7 cluster.
Problem is .. with the new Oracle drivers our actions on the webapp takes twice as long as with Jdriver. We also tried OCI .. same problem. We switched to a single Oracle 8.1.7 database .. and it worked again with all thick or thin drivers.
So .. new Oracle drivers with oracle cluster result in bad performance, but with Jdriver it works perfectly. Does sb. see some connection?
I mean .. it works with Jdriver .. so it cant be the database, huh? But we really tried with every JDBC possibility! In fact .. we need batch input. Advise is very appreciated =].
Thanx for help!!

Thx for quick replys. I forget to mention .. we also tried 10g v10.1.0.3 from instantclient yesterday.
I have to agree with Joe. It was really fast on the single machine database .. but we had same poor performance with cluster-db. It is frustrating. Specially if u consider that the Jdriver (which works perfectly in every combination) is 4 years old!
Ok .. we got this scenario, with our appPage CustomerOverview (intensiv db-loading) (sorry.. no real profiling, time is taken with pc watch) (Oracle is 8.1.7 OPS patch level1) ...
WL6.1_Cluster + Jdriver6.1 + DB_cluster => 4sec
WL6.1_Cluster + Jdriver6.1 + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_cluster => 8-10sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_single => 4sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_cluster => 8sec
WL6.1_Cluster + Ora10.1.0.3 thin + DB_single => 2-4sec (awesome fast!!)
WL6.1_Cluster + Ora10.1.0.3 thin + DB_cluster => 6-8sec
Customers rough us up, because they cannot mass order via batch input. Any suggestions how to solve this issue is very appreciated.
TIA

It's much faster than any 9.X

Poor performance with Oracle Spatial when spatial query invoked remotely

Is anyone aware of any problems with Oracle Spatial (10.2.0.4 with patches 6989483 and 7003151 on Red Hat Linux 4) which might explain why a spatial query (SDO_WITHIN_DISTANCE) would perform 20 times worse when it was invoked remotely from another computer (using SQLplus) vs. invoking the very same query from the database server itself (also using SQLplus)?
Does Oracle Spatial have any known problems with servers which use SAN disk storage? That is the primary difference between a server in which I see this poor performance and another server where the performance is fine.
Thank you in advance for any thoughts you might share.

OK, that's clearer.
Are you sure it is the SQL inside the procedure that is causing the problem? To check, try extracting the SQL from inside the procedure and run it in SQLPLUS with
set autotrace on
set timing on
SELECT ....If the plans and performance are the same then it may be something inside the procedure itself.
Have you profiled the procedure? Here is an example of how to do it:

Oracle 10g vs Oracle 11g query performance

Hi everyone,
We are moving from Oracle 10g to Oracle 11g database.
I have a query which in Oracle 1g takes 85 seconds to run, but when I run the same query in Oracle 11g database, it takes 635 seconds.
I have confirmed that all indexes on tables involved are enabled.
Does anyone have any pointers, what should I look into. I have compared explain plans and clearly they are different. Oracle 11g is taking a different approach than Oracle 1g.
Thanks

Pl post details of OS versions, exact database versions (to 4 digits) and init.ora parameters of the 10g and 11g databases. Have statistics been gathered after the upgrade ?

I'm looking for something about performances of
Oracle 10g Express Edition to make a little
presentation for the University. Can anyone help me?What's the matter with the docco? 1 processor only, 1GB ram, one db

As to how this will affect your* performance, this can only be
done by you testing under given conditions. However, if you are doing
Uni work, why not use the EE - you only have to pay for deployment AFAIK.

Performance: Bulk Insert Oracle 10g

Following Situation: We have a VISUAL BASIC 6 Application (I know ... VB6 ... ), an XML-File with data and an Oracle 10g database. The XML-File has to be imported in the database.
Up to now the Application (Via ADO) analyses the XML-File and creates INSERT and UPDATE Stmts and sends them to the DB. The Stmts will be handled within one Transaction and the application sends each INSERT, UPDATE separate to the database.
But this is a performance desaster... as expected ... :-) The import takes several hours ...
Now, my task is to increase the performance, but how .....
I tried several things, but without the real success, e.g. ...
I performed some tests with the SQl*Loader. The Insert is really fast, but I can't make an Update, so I had to delete the existing data first. But I can't proceed the two steps in one transaction, because of the SQL*Loader.
I tried to write a stored procedure which accepts an ADO.Recordset as input param and then creates the Insert and Update statements within the DB to reduce network traffic, but I didn't find a way to handle a ADO.Recordset as a input parameter for a stored procedure.
Has someone an idea how I can import the XML file in a fast way into the existing DB (and maybe make an Replace of existing records during the import ...) within one transaction without changing the structure of the DB ??? (Oracle packages?? interface in C++ integrated in VB6....) Is there an way to import the XML-File directly to the DB?
Thanks in advance for any idea :-))

I tried to write a stored procedure which accepts an ADO.Recordset as input param ...., but I didn't find a way to handle a ADO.Recordset as a input parameter
for a stored procedure.Use SYS_REFCURSOR as the parameter type. Bulk collect it into a PL/SQL collection. Use FORALL to soup up the INSERT and UPDATE statements.
Cheers, APC

Performance tuning oracle 10G on Windows 2003

Hi,
At present we have 8GB physical RAM on Production server while the parameters sga_max_size = 1 GB and pga_aggregate_target = 629 MB are defined.
When I hit transaction ST02 I observed that values for swaps are showing in red color for program, screen, Export/import, generic key buffers etc. We cannot restart the SAP more than once in a week, and it increases the number of swaps.
We have plan to increase the buffer size by twice for program, screen, Export/import, CUA, Nametab, generic key buffers etc. The addition of current value for all this buffers is defined up to 350MB.
I want to know if I increase this value by twice is it cause any problem to system or I need to increase the size of sga_max_size and pga_aggregate_target also.
Is sga_max_size and pga_aggregate_target parameters are related to program buffer or screen buffer or generic key buffers.
Thanks & Regards,
Rajesh

Oracle 10g performance issues

Hi,
We were using Oracle 9i in Solaris 5.8 and it was working fine with some minor performance issues. We formatted the Solaris server with new Solaris 5.10 and installed Oracle 10g.
Now we are experiencing some performance issues in Oracle 10g. This issue is arising when using through Websphere 5.1.
We have analyzed the schema, index is rebuild, SGA is 4.5 GB, PGA is 2.0 GB, Solaris RAM is 16 GB. Also we are having some Mat Views (possibly this may cause performance issues - not sure) due to refresh.
Also I have changed some parameters in init.ora file like query_rewrite = STALE_TOLERATED, open_cursors = 1500 etc.
Is is something due to driver from which the data is accessed. I guess it is not utilizing the indexes on the table.
Can anyone please suggest, what could be the issue ?

There are a lot of changes to the optimizer in the upgrade from 9i to 10g, and you need to be aware of them. There are also a number of changes to the default stats collection mechanism, so after your upgrade your statistics (hence execution paths) could change dramatically.


Greg Rahn has a useful entry on his blog about stats collection, and the blog al,so points to an Oracle white paper which will give you a lot of ideas about where the optimizer changes - which may help you spot your critical issues.

Otherwise, follow triggb's advice about using Statspack to find the SQL that is the most expensive - it's reasonably likely to be this SQL that has changed execution plans in the upgrade.

Performance Problem between Oracle 9i to Oracle 10g using Crystal XI

We have a Crystal XI Report using ODBC Drivers, 14 tables, and one sub report. If we execute the report on an Oracle 9i database the report will complete in about 12 seconds. If we execute the report on an Oracle 10g database the report will complete in about 35 seconds.
Our technical Setup:
Application server: Windows Server 2003, Running Crystal XI SP2 Runtime dlls with Oracle Client 10.01.00.02, .Net Framework 1.1, C# for Crystal Integration, Unmanaged C++ for app server environment calling into C# through a dynamically loaded mixed-mode C++ DLL.
Database server is Oracle 10g
What we have concluded:
Reducing the number of tables to 1 will reduce the execution time of the report from 180s to 13s. With 1 table and the sub report we would get 30 seconds
We have done some database tracing and see that Crystal Reports Issues the following query when verifying the database and it takes longer in 10g vs 9i.
We have done some profiling in the application code. When we retarget the first table to the target database, it takes 20-30 times longer in 10g than in 9i. Retargeting the other tables takes about twice as long. The export to a PDF file takes about 4-5 times as long in 10g as in 9i.
Oracle 10g no longer supports the /*+ RULE */ hint.

Does anyone have any suggestions on how we can improve the report performance with 10g?

Hi Eric,
Thanks for your response. The optimizer mode in our 9i database is CHOOSE. We changed the optimizer mode from ALL_ROWS to CHOOSE in 10g but it didn't make a difference.
While researching Metalink I came across a couple of documents that indicated performance problems and issues with using certain data-dictionary views in 10g. Apparently, the definition of ALL_OBJECTS, ALL_ARGUMENTS and ALL_SYNONYMS have changed in 10g, resulting in degradation in performance, if quieried against these views. These are the same queries that crystal reports is queriying. We'll try the workaround suggested in these documents and see if it resolves the issue.
Here are the Doc Ids, if you are interested:
Note 377037.1
Note:364822.1
Thanks again for your response.

Oracle 10g performance tuning tools

hi,
can anyone please suggest me any oracle database tuning tool to use for improving the performance of the database?(oracle 10g)

Hi,
Do you want a tuning tool that does not require the user to have in-depth Oracle knowledge? If so, try here:

Seriously, I like to use AWR and STATSPACK reports, and there are some freeware tools to help analyze them, one that I sponsor:

For online tools, Oracle SQL Developer is a great way to get started, as-is the Oracle performance pack:

For third-party tuning tools, look at Confio, quite good:

Hope this helps. . .
