A Java program would call a sequence of 5 PLSQL procedures, and they all need to participates the Tranasction defined in Java.
What do I do for the transactions inside PLSQL to ensure all 5 pariticpate in the Java transaction? I suppose I just do not specify any COMMIT in the PLSQL, but that probably would not work as PLSQL would COMMIT by default after exiting the proc?

View 1 Replies View RelatedI am using Oracle XE with SQL Developer to teach a course on databases.
The students complete a number of small projects. How can a student separate the projects so as to be able to open in SQL Developer only the tables pertaining to a specific project? Ideally, the student would be able to assign the same name to two tables that belong to different projects.
I know that this can be done by naming conventions and filtering, but this is awkward.

View 9 Replies View RelatedWe just purchased NAS (Raid5) unit to manage our data storage. I am planning to create a virtual partition on this nas device and use one partition for oracle data storage and another virtual partition will be used by other data (files and may be sqlserver data files....etc..)
We will have oracle installed on seperate oracle server. Can we use RMAN to manage incremental backups in this environment? May main worry point is that our data storage device will have many different type of datas and will we be able to tell RMAN to make backups only from certain virtual drives?
We are using oracle 10g. with our code, Currently Oracle partitions are size the same way, each partition is using 10MB for data and 12MB for indexes (with the 6 default indexes); even of very few records are written in the partition.
We create partitions in advance as a part of nightly job with 10 minutes duration.Can some intelligence can be added where based on statistics we can decide the size of partition dynamically? Lot of space is getting wasted because of this reason.
I have successfully installed the Oracle 10g standerd version with a sample database on Windows server 2008 standard server. Then I installed the client so that I could use the Enterprise manage console that comes with it. Once installed, I was able to successfully configured the Net service. Now when I use either Enterprise manage console or SQL plus to login to the service that I created, once I enter the user id and password and click ok, system automatically closes both applications. I am not sure what is missing. I installed the same client on a windows XP pc and the enterprise manage console is working perfect.

View 5 Replies View RelatedI have to manage an active passive cluster on SLES10 SP4. Oracle 10.2.0.4. All oracle binaries are on a DRBD Device on mountpoint /oradata. This mountpoint includes the binaries and all datafiles.
I havent installed these systems. At one stage on node died and got reinstalled by a system administrator. After a switch from the running node to the standby node, the cluster is not starting.
Jan 3 14:36:01 a logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.6114.
Jan 3 14:36:14 a logger: Waiting for Oracle CSS service to be available before starting
Jan 3 14:36:14 a logger: ASM instance +ASM. Wait 2.
After issuing $ORACLE_HOME/bin/localconfig add the cluster is starting, the asm instance is coming up, and also the database instance is starting.
Shortly after that the db instance dies. Alert log is showing something like recursive sql error. Looks like writing to the datafiles is not working. In asmcmd the diskgroups are showing DISMOUNTED (show MOUNTED before)
so what to do ?
a) Why is it necessary to issue "localconfig add" to make the cluster starting ?
b) What could be a reason for not being able to write to the database ?
c) How to install an active/passive cluster ?
c1) Install OS on both nodes
c2) Install oracle binaries
c2.1) on both nodes in the local files system and do the mapping to the drbd afterwards?
c2.2) only on one node and just switch the mountpoint ?
I'm developing, or trying, on Apex 4.2...The issue is about themes and how to manage the positions of diferents Display Points of a theme.
Everybody know that any theme have a map where its position all differents parts of this map (Body1, Body2, Body3, position01, position02 and so). So when you choice any theme, it come with all this Display points defined. You can see this map rendering any region page and in the item Display Point you can see this map clicking on the light.
There is anyway to can manage this map and change position or behavior of those points?. For example , I'm interested that under the tabs, to have at the same height, 3 diferentes position, one at left, one at center and other at right.
I would like to change the printing settings in my workspace Instance settings. But, I can't find the "Manage Instance" option mentioned in the tutorials.

I am trying to invoke program from my local Windows machine (exactly java executor, which is in my environment on c:javajdkinjava) using database package with Java stored procedure.
Everything is fired by SQLPLUS script, this script invokes package with Java stored procedure (jar loaded into Oracle) and that procedure is trying to invoke runtime process (syntax:
c:javajdkinjava -cp
and here ara my classes and main jar) using my local java executor. I added all permissions using dbms_java.grant_permisions (execution forced me to give permissions java.io.FilePermission to <<ALL_FILES>> for execute), moreover I added to my database user JAVASYSPRIV and JAVAUSERPRIV role. Unfortunately, beside this I am still getting error:

I was getting java.sql.SQLException: executeBatch, Exception = 1when i tried to use executeBatch().could not understand why i am getting it.
View 1 Replies View RelatedI am writing a java stored procedure in my package. In the java procedure I want to issue a query to be fired on the user table from which I am calling the java procedure.
Some thing like following:
I am logged in to USER1 and my package is inside USER1. From this package I am calling the Java Stored Procedure. In java procedure I want to make a jdbc connection to USER2. The details of USER2(password, hostname,portno) are stored in a table called 'connection_details' and this table is in the USER1.
My problem is how can I issue the
SELECT details FROM CONNECTION_DETAILS for USER2
so that i can get the details..?
Do i need to first make jdbc connection to USER1 and then execute the above query for which i need similar details of USER1. How can i obtain the details of USER1 here.
I am thinking if I am already in USER1 then do I need to make the jdbc connection to USER1 and then execute the query?

View 1 Replies View RelatedI have a table called "Subjects" which lists subjects to match with notations in another table I have created a simple sequence (CREATE sequence subjectid) to created the subject id for the table. But I notice that if there is a skip in the date, the sequence increments automatically when I am not even using it. It even appears to be incrementing even when I am not doing any database activity.
This is not an issue of data integrity, because the values in the subject_id column do not need to be sequential, they just need to be unique. But it really has me curious. I created another table called "keep_track" to keep track of what is happening:

we can you java code natively with Oracle. But I didn't get how to decide when to use native java in oracle and when to use pl/sql.
View 5 Replies View Relatedi`m trying to use pl/sql function to execute java class. I created 2 tables with around 100 values and java class with simple functionality. I need to create function to loop through my table1 and get with each iteration one value from table and pass that value as parameter to java class.
table1 is something like this:
ID NAME
1 name1
2 name2
3 name3

100 name100
table2 is empty with same columns as table1 ( table2 is for data obtained from java returns ) I created in sql+ java class.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "myClass" AS
import java.io.*;
import java.util.*
public class myClass {
public static String fun(String strName)

Then i wanna make a pl/sql function for:
1)For i = 1 Obtain first value from table1 (column name) and pass it throught java class then return value and save it in table2 with the same id as id from table1
2) change i=1 to i=2 and do that same
3) end if i=101
I am trying to select the owner of a certain object, only knowing the name of the object and the user calling it.
Problem is this object might exist in more than one schema with the same name, and I only need the one that is called by the active user, which himself/herself might have access to other schemas containing their own copy of the object.
Example:
SELECT OWNER
INTO v_schema_name
FROM ALL_OBJECTS
WHERE OBJECT_NAME = p_object_name;
This works fine, until the object exists in more than one schema to which the current user has access.
