How to enhance Oracle Datapump Performance (AIX, Oracle 11.1.0.7.0)

For some testing pupose we have to do import a 230GB dump file. This is very time consuming while import.
1. How can I identify the MAX parallesim supported by Oracle 11.1.0.7.0 AIX.? Is it depend upon the no of processor on server.? How can i find that?
2. Will it helpful if the expdp dump from source(production) will taken as compress=y .?
3. Is it advisible to exclude the indexes while impdp import and will create it manually after import. Will it improve the performance and time can be saveed?
(INCLUDE=TABLE_DATA)
Regards,
Sangram Keshari Dash

Hi,
we do a 100GB export and import both in around 15 minutes on AIX 5.3 and Oracle 10.2. We do the export parallel to 4 dump files. Oracle takes the tables in sequence as you give them to the export. We have in this dump 2 big tables, we put them first and then the rest. We see that there are 2 export running on the 2 big tables, and the rest is taken by the other 2. This gives a good balance for export. The import goes the same. We make full exports and imports, so including indexes (also some text indexes). This proces is not CPU bounded (there are 4 CPU), but mostly on I/O (we have a big SAN) or memory.
The best is to give the most memory to Oracle, make the Caching of AIX OS to a minimum, but these are also the best practices to run a database on AIX.
You have to make some test with the parameters of expdp to get the best result, or test export without indexes and with indexes. We also had to do it this way.

How to speed up the performance in Oracle APEX - Classical Report loading

Hi,
I am using APEX 4.2, DB 11.2.
I have created 2 reports in the page and the time that is taken to load this page is very huge.
To speed up the performance materialized views were used on queries, but still the performance is the same.
checked the app in DEBUG mode, the following event takes a lot of time to execute:
0.08415 4.76698 rows loop: 15 row(s) the query onky takes very less time to execute
0.08184 0.00181

Check query performance very carefully. If you execute the SQL more than once in a short amount of time the data will be in memory and accessed more quickly. It is possible that your fast response time was against cached data and therefore faster. If this is the case further tuning the SQL (the MV query) may help.
It is also possible the slowness is due to other factors - network, firewall, antivirus software, etc. I am running Apex on my laptop using the embedded pl/sql gateway and due to antivirus and security software it can take pages 30 seconds or more to load.

How to improve performance of Oracle Forms Server ?

Recently we converted our Application which was Developed in Forms 5.0 and Reports 3.0 into Forms6i to host that on to Web. We also loaded ORACLE 9iAS (on Windows NT 4 with service pack 3) from "Enterprise Edition" option by selecting Oracle Database Cache, Forms Server and Reports Server, HTTP Server(on port 80),Oracle Web Cache. Everything loaded succesfully including Caches.
Forms server is working perfectly and we were able to run our Application in Browser, but performance is the issue. We thought the caches will improve the performance, but it seems they are not at all working. When we run a report or form the Database cache is not giving any statistics whether a particular Query is a Hit or Miss though the cache is running. We got a doubt and searched in FAQ's and we found the following questions.
Oracle9iAS Web Cache Frequently Asked
Questions February 2001
Does Oracle9iAS Web Cache work with applications that use Oracle9iAS Forms?
Not in the 1.x release of Oracle9iAS. Integration between Oracle9iAS Web Cache and Oracle9iAS Forms will be addressed at a future date.
Oracle9iAS Database Cache
Does the Cache work with Oracle Forms and Portal in Oracle9i AS?
Since Oracle Forms and Portal utilize read/write PL/SQL stored procedures, these components cannot take advantage of the Cache. This support is being considered for a future version.
After coming to know that Caches doesnot boost the performance of Oracle Forms and reports. We have the following queries.
1) Clarify whether the above are True.
2) Apart from DB and Web Cache is there any other way where in we can improve the performance of Oracle Forms and Reports in Forms Server including the start up time.
3) What is the ideal configuration required for each tier (iAS Server,Database Server and Client) to host Forms on to Web considering our application as Medium scale.
(Presently our configuration are,
Application Server Configuration : Windows NT 4 with service pack 3,256 MB RAM,1 GB Virtual memory and 4GB free space and almost the same configuration is being used for
Database Configuration.
Client Configuration : Windows 98 with 64MB RAM).
4) Is there any way to track the performance and know the problem areas like TRACE.
Gopi Kumar

A couple of questions for you:
1) What version of IAS are you using?
2) What's the version of Forms&Reports and
3) What version of patch are you using if any
for forms&Reports?
4) What applications are you running on the
machine where Forms&Reports is installed?
(I mean non-Oracle applications?)
The problem could be that, the base addresses
of the DLL's in Forms&Reports could be having base address conflicts with some other application's DLL's.
Forms and Reports needs to be fully rebased to achieve full performance on NT. Before release of Forms and Reports, Oracle rebases all DLLs. Rebasing assigns unique base addresses to all of the DLL's in use by an executable. A properly based DLL will load at its preferred base address, greatly improving the efficiency of memory utilization and the runtime performance of the executable.
Multiple utilities are available on NT to verify proper rebasing of DLLs. HandleEx v4.0 is one such freeware from Sysinternals and is available at www.sysinternals.com. Some others are "depends.exe" that's part of the MS Visual Studio or msinfo32.exe that comes with Office 2000 on NT.
If after running any of these utilities you discover that the DLL's ar not properly rebased, you need to contact Oracle worldwide support.
If you find that rebasing is not the problem, then please post your feedback again. Hope this helps.

How to Migrate the database from AIX 4.3 oracle 7 to another Aix 5.3

Hi,
This is the scenario.
Oracle 7 runs in AIX 4.3 now the client wants to upgrade to a new machine with
oracle 10gr2 in AIX 5.3 .
AIX 4.3 in production now.
AIX 5.3 and oracle 10gr2 installed now.
is there any other possibility other than export to migrate to new server.
Regards
Elamaran

Sorry to disappoint you :( It's the same thing as with my car - If it's not without fuel I turn the key and drive ;)
Confined to the development database instance, writing packages is the only thing I'm allowed to do (even forbidden to use some of the Oracle supplied ones).
There are other guys having to do the rest.

How do I create a db in Oracle 9i Lite?

I have used Oracle 8i Lite on handheld computers in a replicated environment for quite some time now. I am in the middle of setting up a demo tablet computer, but since Oracle 8i Lite is no longer downloadable from the Oracle website, I instead downloaded 9iLite. When I went to install it, my options were Mobile Server and Mobile Development Kit. I went ahead and followed the install wizard without choosing either one of these two options, thinking I would just get the plain Oracle Lite database environment. After the install completed successfully, I went to look for Oracle Navigator and where the Polite.odb was located, but no where do these two items seem to be installed (or copied to).
Somewhere in this forum, a person posted that 9iLite needs 8iLite to be installed already in order to use the basic database functionality. Is this the case? Is there anyway to create a database using my create table script for all the tables in my db. I could see that SQL Plus is installed, which is the app I used to run the script in 8iLite.... but you already need a database to log into in order to run SQL Plus.
How do I create a database in Oracle 9iLite.
Your help is greatly appreciated.
PS: I am somewhat in a hurry, since my demo unit needs to be done by the end of the weekend..... I really did not anticipate this trouble with 9iLite.

Sure but you break the license, or forgive me and a did a mistake

How to store an excel sheet in oracle database

How can I store excel sheet into oracle.

Or you could use Heterogenous Services to treat Excel as an external database:
1- Go to Control Panel>Administrative Tools>Data Sources (ODBC)>System DSN and create a data source with appropriate driver. Name it EXCL.
2- In %ORACLE_HOME%\Network\Admin\Tnsnames.ora fie add entry:
EXCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.12.0.24)(PORT = 1521))
(CONNECT_DATA =
(SID = EXCL)
(HS = OK)
Here SID is the name of data source that you have just created.
3- In %ORACLE_HOME%\Network\Admin\Listener.ora file add:
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = <hs_sid>)
(ORACLE_HOME = <oracle home>)
under SID_LIST_LISTENER like:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = d:\ORA9DB)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = ORA9DB)
(ORACLE_HOME = d:\ORA9DB)
(SID_NAME = ORA9DB)
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = EXCL)
(ORACLE_HOME = D:\ora9db)
Dont forget to reload the listener
c:\> lsnrctl reload
4- In %ORACLE_HOME%\hs\admin create init<HS_SID>.ora. For our sid EXCL we create file initexcl.ora.
In this file set following two parameters:
HS_FDS_CONNECT_INFO = excl
HS_FDS_TRACE_LEVEL = 0
5- Now connect to Oracle database and create database link with following command:
SQL> CREATE DATABASE LINK excl
2 USING 'excl'
3 /
Database link created.
Now you can perform query against this database like you would for any remote database.
SQL> SELECT table_name FROM all_tables@excl;
TABLE_NAME

How can we clone the Oracle database in new Oracle Home

Hi,
I would like to clone oracle database into new oracle home. How can we set it using OEM.
I am using 10g grid control. Target db is on solaris
Thanks
Naveen

after logging into target database, under maintenance tab, data movement header; ther is "clone database" option. When you click on it; you'll see :
Clone Database uses RMAN to duplicate a database from:
-- An open database in ARCHIVELOG mode, or
-- An open database in NOARCHIVELOG mode (restart required), or
-- A saved working directory from previous cloning
Clone Database performs the following operations:
-- Backup each database file and store it in a working directory
-- Transfer each backup file from source to destination host
-- Restore each backup file to existing destination Oracle Home
-- Recover the cloned database with saved archived log files
-- Open the cloned database with resetlogs
It seems to be for cloning to a different host, but i guess you can chose the same host for source and destination. (I've never used cloning on em by the way :))
But firstly, you should create a new oracle home, you can simply copy your oracle home with a new name (cp -R /oracle/app/oracle/product/10.2.0 /oracle/app/oracle/product/10.2.0.new) or make a new installation.
I suggest you to do this cloning with CLI. You should take a full backup with RMAN, copy the oracle home, create a new initNEWSID.ora file and nomount the database, restore (or simply copy) controlfiles, restore database (with set newname commands), recover database, open resetlogs.

How to upload data into form of Oracle EBS R12 using ATS ver 9.0

Hi experts,
Could you please guide me how to upload data into form on Oracle EBS R12 using Oracle Application Testing Suite verson 9.(The simpliest way)
For example: I need to create user account on Oracle EBS. Normally, I use Dataloader to upload the data, however it just can upload one by one record, cannot upload multi record at same time. Moreover if the performance of server is low, so I will get the issue when using dataloader.
Thanks in advance
Best Regards
Hieu

Hi you can create Virtual users to enter data. Note than you have to name the objects accordingly.
For Example default recording provided by Open script is ObjectNAME_(Index No of the object).
when you record one iteration the name of any object would be ObjectNAME_(0)
You can then create virtual users so the index will increment as the total number of Virtual users increases. Also you have to handle which row of your test data would get mapped to which Virtual user in the script run session.
Thanks

Hi Waverly,
No, I have the install doc, what I can't find is the actual installation files.
Seperate sources indicate it is either already available or not available until August. I suspect the later is the case, since we aren't in ramp up.
