One BI and 3 oracle database?

Hi all,
I was installing Oracle 10g and BI on machine with ip 10.0.0.3
I have other oracle 10g on machine with ip 10.0.0.5
How can I set and connect this 10.0.0.5 dbase with BI from 10.0.0.3
regards
gordan,

For Oracle databases you shoul;d not use ODBC but Oracle's native drivers (OCI). The way to set this up is the same than for any other OCI connection from any other box: Install the Oracle client and configure the TNSNAMES so that it knows about the Oracle DB you want to connect to.

DBA Cockpit: Planning calendar and remote Oracle databases- which method?

For using DBA Planning Calendar to schedule BR*Tools for remote Oracle database AS Java systems I have successfully implemented both the Secure Shell and SAP gateway methods in [Note 1025707 - DBA Cockpit: Planning calendar and remote Oracle databases|https://service.sap.com/sap/support/notes/1025707] and was interested in which of these two methods others have found to be more supportable and maintainable?
In more detail, the note has these two methods for non-ABAP remote systems:
2. Connection through Remote/Secure Shell
Specifically Secure Shell. Rejecting remote shell as too old and insecure a protocol.
3 Connection through SAP gateway
The note provides clues as to how these methods work. Expanding on that:
With #2, central ABAP system calls out to its OS user level to execute the ssh client (after gw/rem_start has been set to the non-default value SSH_SHELL) which it finds in the location specified in gw/ssh (default value is /usr/bin/ssh). It must use password-less authentication and the key-based authentication must also not require a passphrase. (Using ssh-agent is not an option since this is being called from SAP, not from your own script.)
It remotely runs via ssh a command, sapxpg, which must be found in the PATH of the remote user. (This is why the note, which has you place this exe sapxpg and a subset of the BR*Tools in the home dir of the remote user, also has you make sure the home dir is included in the path--your OS might or might not include the user's home dir in the path in the default shell environment for a new user.)
Then via sapxpg, the BR*Tools are invoked.
One thing that may be confusing here is you have to check at least one gateway parameter 'gw/...' in the central system to get the method #2 the non-gateway method to work--this is because the two methods are technically almost the same: in #2, secure shell is used to basically start a gateway on the fly with sapxpg in order to call the BR*Tools each time a DBA Planning Calendar action runs or you view DBA or Backup logs of the remote system from the central system. With #3, the gateway runs continuously on the remote system.
With #3, central system connects to remote SAP standalone gateway, which executes the BR*Tools installed in the standard SAP kernel directory of the SAP gateway. This method is simpler to describe so it sounds like it has less components than the secure shell method, however you do have an entire SAP system running, although it is just a standalone gateway.
Thoughts:
These pros/cons are UNIX/Linux-oriented since I assume most Windows environments do not have added 3rd-party products that provide secure shell so SAP gateway is the only method.
Secure shell
+ Less software required (not counting secure shell which comes with the operating system distribution): just a few SAP executables placed in the home dir of an ordinary user on the remote system.
+ Secure shell service probably automatically starts upon boot of the remote system operating system.
+ Secure shell is a widely used tool outside of SAP for executing commands remotely without passwords.
- Installation is non-standard: shell environment of remote user is not adapted by SAP installer since SAP installer is not used, SAP executables in the home dir of the remote user is non-standard. Has to be setup manually.
- Requires setting up secure shell key-based authentication, which should be known by UNIX/Linux admins or combined Basis/UNIX/Linux admins, but might be less familiar to SAP Web AS only admins.
- If your admin config policy is to have SAP interact as little possible with the OS level for interfaces with other systems, here you are relying on the OS-level secure shell.
- Using a private key that does not require a passphrase on the central system may not fit with your security policies if you have standards for secure shell configuration.
SAP gateway
+ The gateway is a standard installation, performed with SAP installation tool, with the exception of a few additional environment settings that have to be added after the installation. BR*Tools are installed in the standard location. Can use standard procedures for updating this software.
+ Only uses SAP software.
- More software on remote system: standalone gateway just to run BR*Tools and view logs.
- SAP Kernel of remote gateway should probably be updated whenever you do SAP kernel updates across your systems for consistency. One more system to update.
- Shell environment of remote user that runs the gateway looks like something setup by the SAP installer but is not standard because it has a few additional environment variables added.
- Need to make sure the SAP gateway is started on the remote system.

Hi Joe,
I configured a monitoring/dba landscape for two SAP Portals and one SAP BusinessObjects system on a SAP landscape by using DBACOCKPIT, at a customer site. These systems are running on AIX, Windows 2003/2008 servers and attached to the central monitoring system with standalone SAP gateway installations.
One another reason to not use OS based commands or 3rd party tools is security. We are stopping and disabling most of the services on OS where SAP system is running on, because of the security reasons. I faced more security gaps on rsh/ssh and the other tools than standalone SAP Gateway installations. As you can figure out that rsh/ssh is getting more attack than standalone SAP Gateway, because of well known by the IT world.
As a summary of it, this depends to point of view and policy of the IT organization. I applied both ssh and standalone SAP Gateway solutions at my customers, but I choose standalone SAP Gateway installation among of them.

Passing Array of java objects to and from oracle database-Complete Example

Hi all ,
I am posting a working example of Passing Array of java objects to and from oracle database . I have struggled a lot to get it working and since finally its working , postinmg it here so that it coudl be helpful to the rest of the folks.
First thinsg first
i) Create a Java Value Object which you want to pass .
create or replace and compile java source named Person as
import java.sql.*;
import java.io.*;
public class Person implements SQLData
private String sql_type = "PERSON_T";
public int person_id;
public String person_name;
public Person () {}
public String getSQLTypeName() throws SQLException { return sql_type; }
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
person_id = stream.readInt();
person_name = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeInt (person_id);
stream.writeString (person_name);
ii) Once you created a Java class compile this class in sql plus. Just Copy paste and run it in SQL .
you should see a message called "Java created."
iii) Now create your object Types
CREATE TYPE person_t AS OBJECT
EXTERNAL NAME 'Person' LANGUAGE JAVA
USING SQLData (
person_id NUMBER(9) EXTERNAL NAME 'person_id',
person_name VARCHAR2(30) EXTERNAL NAME 'person_name'
iv) Now create a table of Objects
CREATE TYPE person_tab IS TABLE OF person_t;
v) Now create your procedure . Ensure that you create dummy table called "person_test" for loggiing values.
create or replace
procedure give_me_an_array( p_array in person_tab,p_arrayout out person_tab)
as
l_person_id Number;
l_person_name Varchar2(200);
l_person person_t;
l_p_arrayout person_tab;
errm Varchar2(2000);
begin
     l_p_arrayout := person_tab();
for i in 1 .. p_array.count
loop
     l_p_arrayout.extend;
     insert into person_test values(p_array(i).person_id, 'in Record '||p_array(i).person_name);
     l_person_id := p_array(i).person_id;
     l_person_name := p_array(i).person_name;
     l_person := person_t(null,null);
     l_person.person_id := l_person_id + 5;
     l_person.person_name := 'Out Record ' ||l_person_name ;
     l_p_arrayout(i) := l_person;
end loop;
p_arrayout := l_p_arrayout;
     l_person_id := p_arrayout.count;
for i in 1 .. p_arrayout.count
loop
insert into person_test values(l_person_id, p_arrayout(i).person_name);
end loop;
commit;
EXCEPTION WHEN OTHERS THEN
     errm := SQLERRM;
     insert into person_test values(-1, errm);
     commit;
end;
vi) Now finally create your java class which will invoke the pl/sql procedure and get the updated value array and then display it on your screen>Alternatively you can also check the "person_test" tbale
import java.util.Date;
import java.io.*;
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.driver.*;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class ArrayDemo
public static void passArray() throws SQLException
Connection conn = getConnection();
ArrayDemo a = new ArrayDemo();
Person pn1 = new Person();
pn1.person_id = 1;
pn1.person_name = "SunilKumar";
Person pn2 = new Person();
pn2.person_id = 2;
pn2.person_name = "Superb";
Person pn3 = new Person();
pn3.person_id = 31;
pn3.person_name = "Outstanding";
Person[] P_arr = {pn1, pn2, pn3};
Person[] P_arr_out = new Person[3];
ArrayDescriptor descriptor =
ArrayDescriptor.createDescriptor( "PERSON_TAB", conn );
ARRAY array_to_pass =
new ARRAY( descriptor, conn, P_arr);
OracleCallableStatement ps =
(OracleCallableStatement )conn.prepareCall
( "begin give_me_an_array(?,?); end;" );
ps.setARRAY( 1, array_to_pass );
     ps.registerOutParameter( 2, OracleTypes.ARRAY,"PERSON_TAB" );
     ps.execute();
     oracle.sql.ARRAY returnArray = (oracle.sql.ARRAY)ps.getArray(2);
Object[] personDetails = (Object[]) returnArray.getArray();
Person person_record = new Person();
for (int i = 0; i < personDetails.length; i++) {
          person_record = (Person)personDetails;
          System.out.println( "row " + i + " = '" + person_record.person_name +"'" );
                    public static void main (String args[]){
     try
                         ArrayDemo tfc = new ArrayDemo();
                         tfc.passArray();
     catch(Exception e) {
                    e.printStackTrace();
          public static Connection getConnection() {
     try
                         Class.forName ("oracle.jdbc.OracleDriver");
                         return DriverManager.getConnection("jdbc:oracle:thin:@<<HostNanem>>:1523:VIS",
                         "username", "password");
     catch(Exception SQLe) {
                    System.out.println("IN EXCEPTION BLOCK ");
                    return null;
and thats it. you are done.
Hope it atleast helps people to get started. Comments are appreciated. I can be reached at ([email protected]) or [email protected]
Thanks

Hi Sunil,
I've a similar situation where I'm trying to insert Java objects in db using bulk insert. My issue is with performance for which I've created a new thread.
http://forum.java.sun.com/thread.jspa?threadID=5270260&tstart=30
I ran into your code and looked into it. You've used the Person object array and directly passing it to the oracle.sql.ARRAY constructor. Just curios if this works, cos my understanding is that you need to create a oracle.sql.STRUCT out of ur java object collection and pass it to the ARRAY constructor. I tried ur way but got this runtime exception.
java.sql.SQLException: Fail to convert to internal representation: JavaBulkInsertNew$Option@10bbf9e
                    at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
                    at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146)
                    at oracle.jdbc.oracore.OracleTypeADT.toDatum(OracleTypeADT.java:239)
                    at oracle.jdbc.oracore.OracleTypeADT.toDatumArray(OracleTypeADT.java:274)
                    at oracle.jdbc.oracore.OracleTypeUPT.toDatumArray(OracleTypeUPT.java:115)
                    at oracle.sql.ArrayDescriptor.toOracleArray(ArrayDescriptor.java:1314)
                    at oracle.sql.ARRAY.<init>(ARRAY.java:152)
                    at JavaBulkInsertNew.main(JavaBulkInsertNew.java:76)
Here's a code snippet I used :
Object optionVal[] =   {optionArr[0]};   // optionArr[0] is an Option object which has three properties
oracle.sql.ArrayDescriptor empArrayDescriptor = oracle.sql.ArrayDescriptor.createDescriptor("TT_EMP_TEST",conn);
ARRAY empArray = new ARRAY(empArrayDescriptor,conn,optionVal);If you visit my thread, u'll see that I'm using STRUCT and then pass it to the ARRAY constructor, which works well, except for the performance issue.
I'll appreciate if you can provide some information.

Shamik

Difference between Oracle SID and an Oracle Database

Hi
Can any one please differeniate what exactly is the difference between an Oracle SID and a new Oracle Database?
We just need to create another instance of an application (so we need another copy of all tables).
So either we can:
1. New database SID created or
2. New user created in existing schema or
3. New database provided
Which is the best approach?

Hi,
New database SID created orThat is equivalent of creating a new database in your case.
New user created in existing schema orYou meant new schema(user) created in existing database. I assumed this because you do not want both application to update the same table copy, but different copy.
3. New database providedIt all depends on your you whether you want to create a new database or a new schema for getting another copy of table.
Some points which I take in mind
1) If I have a production database and I need to create a new set of tables for testing or any other purpose, I would create a new database.
2) If I have a test database and I need to create a new set of tables for testing or any other purpose, if possible I would create a new schema in existing database.
3) If I am running less in resources(hardware/memory), I would be createing a new schema in existing database.
4) If I am not running less in resources and I would to keep these two copies entirely different, then from security purpose I would create a new database.

Interactions between Oracle XE and other Oracle database or products

Hello,
My computer is already supporting Oracle 9i Developer Suite and I would like to know if there is some possibles interactions with Oracle database XE which I plan to install on the same computer.
Thank you

Ivok - To answer your first question, each of those two versions is the latest version to run on Oracle SE/EE and Express editions, respectively. Version 2.0 does not run on Oracle Express Edition and Version 2.1 runs only on Oracle Express Edition. Applications developed in either version of Application Express can be installed and run in the other version.

How does one connect to an Oracle Database using OO4O as sysdba using VB 6?

Hi,
Can any one give suggestion to connect an Oracle Database using OO4O as sysdba using VB 6.0. Generally it supports only database, userid/password only.
For Eg:
Option Explicit
Dim m_oraSession As Object
Dim m_oraDatabase As Object
Private Sub Command1_Click()
Set m_oraSession = CreateObject("OracleInProcServer.XOraSession")
Set m_oraDatabase = m_oraSession.DBOpenDatabase("Database", "user/password", 0&)
MsgBox "Connected to " & m_oraDatabase.Connect & "@" & m_oraDatabase.DatabaseName
End Sub
Private Sub Form_Unload(Cancel As Integer)
Set m_oraDatabase = Nothing
Set m_oraSession = Nothing
End Sub
Thanks & Regards,
Kishore.P
E-Mail: [email protected]

You can't connect AS SYSDBA with OO4O.

How to Install emacs, openssh and start oracle database and get a connect?

As suggested by another poster, I installed the prebuilt appliance at [http://www.oracle.com/technetwork/community/developer-vm/index.html] and [http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html] with the intent of running oracle database in a linux vm as a guest on windows 7 and connecting to it using JDBC from the windows host.
This is running but I don't know how to install other stuff. I tried "sudo yum install openssh" and "sudo yum install emacs" and "sudo service sshd status" and none of these worked (it could not find these packages). I could not get apt-get or app-get or aptget to work either. I was hoping that "uname -a" would tell me if this was fedora or debian or something else but no luck. What command do I use to learn the distro name?
How do I make ifconfig tell me what the ip address so I can use "scp" and "ssh" to get into the box? Ok, /sbin/ifconfig works and I see there is only a loopback address. Ack! How do I create a socket so I can ssh into this little beastie?
How do I disable the firewall or (better yet) punch holes in it so I get use JDBC and ssh, scp and samba from windows 7?
I tried firing up the SQL Developer 3.1 and getting a test connection with username and password of "oracle" with no luck. How do I get a test connection to work?
How do I determine if the database is running? If not, how do I start it and stop it and restart it?
Thanks
Siegfried

There is no "oracle" account native to the database itself. This is just the default account that owns the application. Log on as oracle/oracle to the OS. (OEL) You can change the passwords of the sys and system account by setting your $ORACLE_HOME and $ORACLE_SID. Default SID is orcl on a database install. Also set a path to the oracle binaries in the form of $ORACLE_HOME/bin.
Then sqlplus / as sysdba
Change passwords of sys and system using the following example.
ALTER USER SYS IDENTIFIED BY [password];
ALTER USER SYSTEM IDENTIFIED BY [password];
The supplied appliance runs oracle enterpirse linux. Not debain or fedora.
Why do you need "emacs"?
I haven't personally load this appliance with Virtual Box but there has to be a readme file somewhere that details all the passwords and etc.

ADF and not Oracle database

Hi all. In trace log I see that ADF creates such SQL for a lock row :
[NNN] Executing LOCK "SELECT ... FROM TABLE WHERE PK=? FOR UPDATE"
but I use FireBird as SQL Server and for this database syntax has to be
"SELECT ... FROM TABLE WHERE PK=? FOR UPDATE WITH LOCK"
what can I make that the text of sql was generated for FireBird? Owerride method buildDMLStatement?

Hi,
have a look here http://www.oracle.com/technetwork/developer-tools/jdev/multidatabaseapp-085183.html
and also make sure you use a database ADF BC supports or consider EJB/JPA as a model

CURRENT_TIME and non-Oracle Database

Folks !
When I use CURRENT_TIME in JPA named query, TopLink (Essentials) translates it into a "sysdate" function - this doesn't work on non-Oracle database like Postgres.
How do you get Toplink to substitute correct function for non-Oracle Database ?
thanks,
-Sanjay

I set following in my persistence.xml:
<property name="toplink.target-database" value="PostgreSQL" />
Still no luck.

Join between Oracle and non-Oracle Database

We are working at a project with the follow architecture:
- 5 Databases (3 Oracle, 1 Sybase and 1 DB2);
- Session Bean like Session Facade Pattern;
- Entity Bean (BMP);
- OC4J (Oracle Container for J2EE);
The case is that we cannot make join between tables of different bases, for example, join with one table of Oracle and one other of DB2, therefore the customer does not possess tool midleware for this.
The idea that appeared was: we make a query in table XXX of Oracle and return a HashTable with its respective VO�s and Keys (PKs from the first query that will serve of base for the second query), later we have access the DB2 that one second collection would return, to inside make join of the application.
The problem is that with this solution, we will have fall in the performance. And we do not know if it is the best form.
Do you have any idea???
Thanks,
Eric Sander

Hi,
If you have different databases then the join has to be done in the VM (either by the appserver or by you).
If you want to do it yourself, I would try the following:
-write one DAO per business object (at least one per database)
-this DAO contains the specifics of its database
-return a hashtable of keys and VOs from one DAO (as you say you do?)
-in the other DAO, add a method "joinWith ( Hashtable foreignKeys )" that will return the join's result
-implement the method along these lines:
1. retrieve the candidate rows from the second DAO's tables (1 query execution)
2. put the keys in a new Hashtable, say "candidateKeys" (meaning 1 iteration over all results)
3. iterate over all elements of foreignKeys (1 iteration)
4. for each element, check if a key exists in "candidateKeys" (1 hash lookup, very fast)
5. add any such row to the result
This is called a hash join (Oracle does it internally if you do a join).
It is the fastest algorithm to do joins.
Best,
Guy

Performance Issue : Application and oracle database in different sub-net

Hi,
We have an 24/7 application that uses oracle 11g R2 as the back end database. The application sits on a separate box and the oracle database sits on a separate box.
Unless we keep both the machines in the same sub-net, the throughput of the application becomes very slow and kind of un-usable in performance setups.
In fully loaded conditions, the application will be inserting around 12K records per minute into the database. In such scenario, restarting the application takes longer time (more than 2 hours) when the oracle server is on a different network as compared to the application. In real world, the oracle will be in a separate dedicated network and the DBAs resist to have an application in the same sub-net.
Is there a way we can keep the application and the oracle database server in a different network (but present in same location) and achieve same throughput/performance when both servers are on same subnet.
Thanks,
Krishna

Difference between Oracle Database XE and APEX?

I searched, but couldn't seem to find if this question had already been answered.
I just picked up beginning oracle application express by wrox.
I came to oracle and downloaded Oracle Database XE then went to search for apex.
Installed Oracle Database XE ..signing is as system your options appear to be administration, object browser, sql, and utilities.
unlocked the HR sample user account and logged in..it has the same options above, but also application builder.
So, I guess my question is..
1. why does HR have application builder, but system does not?
2. do you need to download and install Apex or is apex already preinstalled using Oracle Database XE?
3. is Apex the same thing as application builder or are they completely different.
Thank you for you answers
Thomas

Oracle 11g XE is the FREE version of the Oracle database product.. APEX is the development product that LIVES in the Oracle database. So if you download the database, you get a copy of APEX to use...
System is NOT a usual user in the database, and in fact you should NOT be using it unless you need to change some settings in the database..
Thank you,

Hello.
Can anybody explain, how should I understand this "Certification Information" from Oracle metalink?
==Quote ==
"Oracle Database is certified with the following Windows Server 2008 editions:
* Windows Server 2008 Standard (x86 and x64)
Oracle Database does not support Hyper-V and Server Core in Windows Server 2008.

Does it mean that this OS is supported, but only if it does not run in Hyper-v configuration?
Thanks for your advice.
