Is there any impact on the Oracle server?

Hi all, currently i have an Oracle Application Server and the current version is 9.0.2.0.0. And another server is Oracle database 9i.
Could anyone tell me if there would be any impact on the oracle database server or the application if i want to install the new version (10.1.2.0.2) of Oracle AS? thx a lot.

Actually there could be anything from no impact to a severe impact, depending on what you want to achieve.
If you let your current environment unchanged and do a fresh install of the 10.1.2.0.2 nothing will happen. If you want to upgrade the 902 into 101202 than you should read the very detailled upgrade guide.
Give us some more details and maybe we are able to answer your question.

Oracle cache is still there after I restart the Oracle server - can it be?

Hello,
My name is Tal and I work for a software company called Mercury.
We have a strange case in Oracle 9.2.0.6 (running on Solaris 2.9) and I wonder if one of you can help.
I am running query, this query is doing something like âselect * from x where y between z and wâ.
x, y, z and w are parameters which cause the query to be one that scans a lot of data.
I run the query twice and the first time takes 60 seconds, but the second time takes only 3 seconds.
I assumed that this is caused by the database cache (block buffers).
BUT,
Then I bounced the database (shutdown immediate + startup) and rerun the query.
It comes back after 3 seconds again!!!
Can some share some info on this; it looks like Oracle cache is still there after I restart the Oracle server.
Tal Olier ([email protected]).

Regarding the buffer cache, it is definitly flushed after database restart.
There can be many factors causing your case:
1. The first time you ran the query, some other process was consuming the server resources.
2. Some other users were running heavy queries.
3. Sudden Heavy network activities.
Q: Did the query, in any time, run in 60 seconds again?
If yes, then further factors should be considered.

Is there any impact that apply Oracle CPU on standby and primary DB

We plan to apply Oracle April CPU on standby DB at this weekend. Then apply the same patch on primary DB next weekend. If I apply the patch on standby, then enable redo apply between primary and standby, is there any impact on primary DB. Theoretically, I don't think so. However, both DBs are production. I want to make sure there is no any impact by applying CPU in different time. Otherwise, I have to apply both DBs at the same time. Please advise. Thanks in advance.

I hope you read other people's post carefully. Don't pretend yourself is expert so that you can say whatever you want to say. This is the tech forum for Oracle technical people to ask question, seek help and so on. How do you know I didn't review document 278641.1 before I asked my question. Document 278641.1 only provide info on how to apply patch on primary and standby. Didn't say anything about applying the same patch on both DBs with data Guard at the different time. I just want to make sure If I apply patch on both DBs with one week difference, will this affect my primary database? Is there anything wrong here. If you paly in this forum as expert, please help people, not just look down people.
I suggest you review [url http://www.catb.org/~esr/faqs/smart-questions.html]How To Ask Questions The Smart Way.
When you ask for help, state the platform, operating system, Oracle version and patch level, no matter whether it seems important to the question or not. It most often is important. You may not know the difference between Itanium and PA-RISC, but that is important for Oracle and important for someone doing administrative work on an Oracle database to know. You should also learn to search the internet for answers to common questions. Everyone here wants to help, but few want to spoon-feed.
When you have any kind of standby, that constrains what you can do to a primary, if you want the standby to work properly. You need to understand how things get from one to the other, and how to decide when to simply rebuild the standby from scratch - and that decision is based on your configuration and requirements. You don't want to be in some undefined configuration for any period of time.

Is there any impact if the files in the Log/ Cache folder are deleted?

Dear All,
We are working on BODS v4.1 SP2 and it looks like some log files in the application server are taking about 30GB of space.
The folder path on the server is
Program Files (x86)\SAP BusinessObjects\Data Services\Log\Cache
and the 4 files are named
PPF_file_21_116_56_1761_1_0_21
PPF_file_21_116_56_1761_1_1_21
PPF_file_21_116_56_1761_1_2_21
PPF_file_21_116_56_1761_1_3_21
Will there be any impact if these files are deleted from the above folder? Anybody has come across this issue before?
Thank you!
Sriram.

Hi Sriram,
Log files are generally .txt which won't occupy much space. But .dmp files occupy huge amount of space and is better to remove it once in a while. Both log and dmp files can be removed to free the disk space. The files in pcache folder are used while running the job because your jobs are executed with pageable cache and not in-memory, hence those files are needed while running the job.

Is there any impact on database if we change the time of server?

Hi,
Our DB server time is 45 minutes ahead of our application server. We have planned to reset the time of database server. Is there any impact on database if we change the timing of the server?

SYSTIMESTAMP

That's an application question, not an Oracle question.
Oracle doesn't care what time it is or when the time changes. Your application(s), however, may care. If you use SYSDATE to populate a row and rely on the date later to be unique or to indicate the actual order rows were inserted, changing the date on the server, particular moving it backwards, might cause problems for your application. Does your application have problems running during daylight savings time changes?

Is there any impact if we delete the indeces on Ods

Hi Experts,
The data does not get updated until and unless we activate the indices of ODSes .This has to be done everytime, when we are loading data from ODS.
We are facing the problems in WBP900 as we are loading data from ODS to infocube .
Is there any impact, if we delete the indeces please let me know.
Thanks In advance
Sivanand

Deleting index will not create any problem , but if the indexes are used by the queries and if the indexes are relevant, then..
But you can always rebuild the indexes.

Insert data 32K into a column of type LONG using the oracle server side jdbc driver

Hi,
I need to insert data of more than 32k into a
column of type LONG.
I use the following code:
String s = "larger then 32K";
PreparedStatement pstmt = dbcon.prepareStatement(
"INSERT INTO TEST (LO) VALUES (?)");
pstmt.setCharacterStream(1, new StringReader(s), s.length());
pstmt.executeUpdate();
dbcon.commit();
If I use the "standard" oracle thin client driver from classes_12.zip ("jdbc:oracle:thin:@kn7:1521:kn7a") every thing is working fine. But if I use the oracle server side jdbc driver ("jdbc:default:connection:") I get the exception java.sql.SQLException:
Datasize larger then max. datasize for this type: oracle.jdbc.kprb.KprbDBStatement@50f4f46c
even if the string s exceeds a length of 32767 bytes.
I'm afraid it has something to do with the 32K limitation in PL/SQL but in fact we do not use any PL/SQL code in this case.
What can we do? Using LOB's is not an option because we have client software written in 3rd party 4gl language that is unable to handle LOB's.
Any idea would be appreciated.

Thank u...!

Hi there.
If You run

and yes , you could do backup while users are connect to db you are backing up.

Is there any way to start weblogic server with java 7?

Hi. Is there any way to start weblogic server with jdk 1.7?

Hi,
You can start your Weblogic Server with java 7(JDK 1.7)
Go to Domain_home/bin and click on StartWeblogic.cmd it will start your Admin Server
It depends on which JDK you have used while creating domain if you have selected Jdk 1.7 it will use the same to start the server
See the Ex:
================
starting weblogic with Java version:
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

If you are using a Lower version of JDK and want to upgrade to JKD 1.7 you can do so by changing setDomainEnv.sh in Weblogic
Have a look at the below link to do so

Is there any control on the number of child records returned

Hi,
I am using web services 1.0 to return child records for an account. Is there any control over the number of child records that are returned. From what I can see it is above the default for 10 for parent record query and i would guess it returns up to 100 records?

In DSP 2.5, the 'streaming' api (which can be used only from a client in the ALDSP server instance) does not have a limit to the size of the results. The standard DSP 2.5 api causes the results to be materialized in memory - so you are limited to what memory you have available. (also, WLS server has a default limit of 10M for a request/response - can be increased in the WLS console - I think it's under 'Protocols').
The JDBC api has no limit on the result size - you might be better off using this for a reporting tool.
In DSP 3.2, there is no limit on the result size.

Is there any option to install SQL server in mac os 10.9

is there any option to install SQL server in mac os 10.9

Hi PREM,
If I understand correctly, you want to use SQL Server Authentication log to SQL Server Integration Services.
Based on my research, only Microsoft Windows Authentication is available for SSIS. So we cannot use SQL Server Authentication log to SQL Server Integration Services. Besides, we can only add OS users in the DCOM Config permission area.
Reference:
Connect to Server (Integration Services)

Is there any known problem using Oracle SQL Developer 3.0.04 with Java 1.7?

I'm new to Oracle. I have installed Oracle SQL Developer 3.0.04 and Java 1.7. When I run Oracle SQL Developer, I will get the window Running this product is supported with minimum Java version of 1.6.0_04 and a maximum version less than 1.7. This product will not be supported....
Is there any known problem using Oracle SQL Developer 3.0.04 with Java 1.7?
I have already downloaded Java 1.6 but don't know whether I need to uninstall Java 1.7 first. If don't need to uninstall Java 1.7, how can I set Oracle SQL Developer to run with Java 1.6?
Thanks for any help.

Hi,
One prior post discussing the use of Java 7 is:
SQL Developer 3.0 and Java SE 7?
There is no need to uninstall any Java version (except if you have disk space constraints) and no problem switching between Java versions. This may be controlled in the sqldeveloper.conf file in your ...\sqldeveloper\sqldeveloper\bin directory via the SetJavaHome line. For example:
#SetJavaHome ../../jdk
SetJavaHome C:/Program Files/Java/jdk1.6.0_26
#SetJavaHome C:/Program Files/Java/jdk1.7.0Regards,
