Isqlplus sysdba problems: 10G

windows XP pro with sp 2, downloaded java
When I did this step cd %ORACLE_HOME%\oc4j\j2ee\isqlplus\application-deployments\isqlplus
%JAVA_HOME%\bin\java -Djava.security.properties=%ORACLE_HOME%\oc4j\j2ee\home\config\jazn.security.props -jar %ORACLE_HOME%\oc4j\j2ee\home\jazn.jar -user "iSQL*Plus DBA/admin" -password welcome -adduser "iSQL*Plus DBA" myiSQLPlusUserName myiSQL*PlusUserPassword
I got: Could not create the Java virtual machine.
I have java downloaded, at
C:\Program Files\Java\j2re1.4.2_06
What do I need to do? Also:
should myiSQLPlusUserName be sysdba ???
Thanks Eric

I would suggest using the JRE that ships with the Oracle Database installation. So, try setting JAVA_HOME to %ORACLE_HOME%\jdk.
You can use any username/password combination you like for setting up the iSQL*Plus DBA URL. This is not related in any way to the Oracle Database logins.

Isqlplus login problem

I have just intalled Oracle 10g. I set all the password as same. But I am not able to login into isql*Plus. I tried different ways via EM, Command line and Windows mode. But no one take the password. Is there a default login username password for iSQLplus?

Tell the error code of ur problem. it will be easier to understand.
One more thing, don't mention the host string any value then try once again. This is because explicitly u r mentioning the location where one instance is available. If more instances in same pc then u use the host string.

Missing isqlplus.conf in 10g install?

Hello
I have installed 10g database including client and companion CD onto a Linux machine (Red Hat AS 3). All seems to work OK but I cannot get iSQL*plus to work via Enterprise Manager. The sign-on screen comes up but when I try to conenct to <hostname>:5560 I get a connection refused message.
The isqlplus application starts ok (isqlplusctl start). I cannot find however a file isqlplus.conf which seems to be relevant, there is a file isqlplus.ini which is a windows file?
Hase anyone managed to get a browser conenction into isqlplus in 10g?

Problem solved!
CJJ thank you for the reference which was extremely valuable.
The problem was that issuing the command "isqlplusctl start" as the Oracle user didn't actually start the service despite the fact that the message saying that it had started was written to the terminal! I was puzzled as to why there was nothing written to the application log until I saw it was owned by root. If I issue the command as root however then it works fine and I can access iSQL*plus from within Enterprise Manager.
David hope this work for you!
Thanks again CJJ

Login as sysdba problem...

Hi,
I've created my own database to make tests on Oracle and directly after that I've changed the passwords for all the users (sys and system users included).
When I try to login without the sysdba role, Oracle applies the password verification fine.
The problem is when I try to login as sysdba:
$> sqlplus 'sys as sysdba'
I can enter whatever password I want and I'm connected !!!
And it's the same if first I type:
$> sqlplus /NOLOG
SQL*Plus: Release 9.2.0.1.0 - Production on Wed May 7 13:21:44 2003

Could someone help me to find where It comes from and how I do solve this security hole...

What's the OS? Are you signed on to the OS as a user in > the DBA group?I'm using a Debian 3.0 (Woody) operating system with a Linux 2.4.18 kernel
I've got only one user which is a member of the DBA group and what I experienced, It's true, was only when I was logged as this user...
Does it means that when a user is a member of the DBA group on the operating system, even if the remote_os_authent parameter is set to false, he can login with sys as sysdba as he wants trough sqlplus ?

SYSDBA - problem with viewing other users package body texts on sys account

Hi,
SQL Dev 1.0.0.15.27 has problem with correct display of other users package body texts on sys account. All bodies have "create or replace" text instead of all pck. bodies text.
I guest it's problem with SYSDBA role. On system account text is displayed correctly. Quest SQL Navigator 5.x has no problem with this. Any ideas ?

Hi Everyone,
Just so I can close the case on this issue, although I was successful in
using CSS to resolve the issue, actually, the issue was not really
resolved. There was (for me) still the problem of rollover images not
working in IE, and if I were ever to get another good night's sleep, I
would need to resolve it -- so I did. Recall me saying earlier about the
sizes being brought in to the javascript code by Dreamweaver? The original
issue with having the size of the small image in the code caused the code
to see the larger image as small also! However, when I deleted those size
attributes' numbers, I failed to delete the words "width" and "height"
along with the double quotes following each. So, while the other browsers
ignored these "blank" attributes within these double quotes, IE apparently
didn't, reading these "blank" values as some very small value, thus
displaying the image in the absolutely smallest size possible! Wow! When I
removed these two blank attributes, my problem went away! Live and learn!
So, to all who were desperately trying to assist me, please accept my
deepest and most sincere apologies. All the while I was blaming IE, I was
the guilty one!!! Shame on me, and thanks for the wonderful responses I
received from the Dreamweaver forum team. I will go and stand in the corner
for 8 hours with my dunce cap on...

Stored Procedure Concurrency Problem 10g

dear all,
Please any one could help on this my problem is appreciated.......
i'm generating ticket numbers using stored procedure as below .
i need to know followings .....(i'm using oracle 10g)
1 .Does oracle stored procedure handle concurrency by default or does db manage concurrency when we using sps or do we have handle concurrency inside a stored procedure?
2.when i generating ticket no using this stored procedure is there any concurrency issue when 100 clients are access it concurrently???
3. Is there issue or bug in my java code??????????
4.I have already used select for update statement but when i used that in db rowlocks are hanging and db become stuck .........
SELECT serial_no into newSerial FROM SERIAL_TAB WHERE BR_CODE=xbranch AND SCH_CODE = xscheme for update;
5. and in my where clause i pass branch and scheme eg:SELECT serial_no into newSerial FROM SERIAL_TAB WHERE BR_CODE=xbranch AND SCH_CODE =
xscheme;
when i run this sp oracle return the error 'more than one row return by query'
but when run query seperately it will return exactly one row for same brach code and scheme code no duplicates.
why this happen and it also happen to update statement it will ignore branch code and update for all schemes
UPDATE SERIAL_TAB SET serial_no=newSerial WHERE BR_CODE=xbranch AND SCH_CODE = xscheme;
what should i do ? sorry for my long question since i'm in deep trouble.....................
could any one can help please................................
in my java code i use transaction and setAutoCommit(false) when calling this sp
public String getTicketNo(String br,String sch){
//getconnection
//setAutoCommit(False);
//call sp get return value ;
//commit;
//if error rollback transaction
create or replace PROCEDURE sp_generate_ticket (
xbranch in varchar,
xscheme in varchar ,
xresult OUT VARCHAR
) AS
BEGIN
newSerial:=0;
SELECT serial_no into newSerial FROM SERIAL_TAB WHERE BR_CODE=xbranch AND SCH_CODE = xscheme;
newSerial:=newSerial+1;
UPDATE SERIAL_TAB SET serial_no=newSerial WHERE BR_CODE=xbranch AND SCH_CODE = xscheme;
--- do other operations -------------------------------------------------------------------------------------
END;

1 .Does oracle stored procedure handle concurrency by default or does db manage concurrency when we using sps or do we have handle concurrency inside a stored procedure?Oracle is a multi-user and multi-process system. It supports concurrency. It also requires the developer to design and write "+thread safe+" code. Its concurrency cannot address and fix design flaws in application code.
2.when i generating ticket no using this stored procedure is there any concurrency issue when 100 clients are access it concurrently???That depends entirely on WHAT that procedure code does. And whether that code is thread safe.
4.I have already used select for update statement but when i used that in db rowlocks are hanging and db become stuck .........
SELECT serial_no into newSerial FROM SERIAL_TAB WHERE BR_CODE=xbranch AND SCH_CODE = xscheme for update;Horrible and utterly flawed approach. This forces serialisation. This means if that procedure is call by a 100 clients, only a SINGLE client can be serviced at a time. ALL OTHERS need to queue and WAIT.
Serialisation kills database performance.
What you have is a serious design flaw. Not an Oracle issue. And there is no magic solution to make this flawed approach work in a performant and scalable manner. This flaw introduces artificial contention. This flaw enforces serialisation. This flaw means that your application code WILL step on its own toes time and time again.
The proper solution is to fix this design flaw - and not use poorly conceived procedures such as sp_generate_ticket that violates fundamental concurrency principles.

In order to connect as SYSDBA, you need to create the DBA username and password. Open a DOS prompt window, and execute the following command:
cd d:\oracle\ora92\Apache\Apache\bin
htpasswd -b d:\oracle\ora92\sqlplus\admin\iplusdba.pw plusdba oracle
You need to stop and start your Oracle HTTP Server for this new alias to take effect.
Check this link:
http://www.oracle.com/technology/obe/obe9ir2/obe-mng/isqlplus/isqlplus.htm
To stop and start the Oracle HTTP Server. On Windows do the following steps:
Open a Windows Command Prompt.
Change directory to the Oracle HTTP Server home directory by entering:
cd %ORACLE_HOME%\Apache\Apache
Stop the running Oracle HTTP Server by entering:
apache -k shutdown
Start the Oracle HTTP Server by entering
apache -k start

Password problems 10G 10.1.0.2

Why am I constantly having problems with the page to enter DB credentials for starting/stopping the DB from Enterprise Manager? I'm sure I understand the input fields presented: Host credentials are the name and password I use for logging into my Server OS, and credentials for the target database are the name and password I use for the account I use for SYSDBA role in my database, correct?
I can log on and start up/shut down the DB with no problems using the command line window. Does anyone have any thoughts on this?

Hello,
What's your OS? If it's windows you can add a new user from control panel-->Users or use one of the existing users
On windows
Go to control panel --> administrative tools --> Local security Policy --> Local Policies --- Users Right Assignments ---> Log on as a batch Job and add your new user or existing user and apply.
Once done use that user as your host crendentials

Instalation Problem - 10g - DHCP machine - Forms too slow if connected

Just installed the latest release of Oracle Database and Developer Suite (10g) on a machine with cable connection to the Net, with DHCP.
Followed the instructions regarding the installation of the Loopback Adapter. It was not possible to follow all the instructions there since my computer is not on a domain.
In any case, I managed to get the Database and DevSuite to work.
There is however one problem:
- when I run a form, the browser is started, the java aplet is loaded, but then, if I am connected to the internet, it takes a very long time to load the form.
- however, if I am disconnected from the internet, then the form loads very fast.
Does anyone have any suggestion on what the problem may be, or where to start looking?
Thank you in advance.

Carry out a traceroute to see if you connection to your own machine is first going to the internet.

OC4J - PROBLEM 10g ( 9.0.4 ) - exception: ORA-01002

I have application perfectly running in the version 9ias (OC4J 9.0.3) when I migrated for 10g (OC4J 9.0.4) I obtained the following mistake stopping my application.
exception: ORA-01002: fetch out of sequence
Data of the application:
     EJB CMP
     Version Database: Oracle 9.02
     Operating system: Solaris 64 bits
I already made several researches and I verified the following problem:
The table TB_CARDS have a lock-mode = "Pessimistic" in the file orion-ejb.xml. In the 9.0.4 we Monitored the access in the database and have syntax : select * from tb_carts for update ("select for update"), but in the version OC4J 9.0.3 it doesn't have the syntax "for update"
     Some people talk to me to put the autocommit equal false, however where i put this option because I´m using using CMP?
     Am I following the correct manageable ?
I await suggestions

ISQLplus install problem

I am trying to install iSQLPlus on a Windows 2000 server. I have 8.1.7 enterprise edition installed currently with just the sample database. The oracle http server seems to run fine and loads the iplus signon form. When I try to enter the login info it either gives me a "server contacted, waiting for response" and stops functioning or it gives me a 404 not found.
I followed the install instructions carefully and rechecked them. There was one point of concern. The doc says to copy plus.dll to the oracle home bin dir. I did not see this file anywhere in the zip but there was a plusdll.dll file. I assumed the doc was a misprint so I moved this file. After the problems were apparent I created a copy of the plusdll.dll file as plus.dll. Still nothing.
Any ideas?
TIA

Alan,
You're right about the dll name. There was an error in the documentation. It should be plusdll.dll as delivered in the zip file. You can delete the copy you made called plus.dll.
Try these and let me know how you go:
1. Make sure you've entered the full URL in the browser, eg, http://mymachine.mycompany.com/iplus/index.html. Don't use /iplus/index.html.
2. If you use a proxy server or firewall, make sure your browser is set to avoid using it (proxy exception) when accessing iSQL*Plus. See chapter 2 of the iSQL*Plus doc for details on doing this.

Cursor Focus Problem - 10g

Hi,
I have an application that was just migrated to 10g from 6i. When a user is entering data on the form and then goes to another window (Alt-TAB) ,then when he returns to the application, the cursor loses focus. The cursor is not in the item it was in before he navigated out of the application.Any ideas how to solve this?
Regards
ephsan

then goes to another window (Alt-TAB) ,then when he returns to the application,Could u pls clear this ou..?
Does then goes to another window (Alt-TAB) in the same application or he just browse to another explorer surfing the net..?
Well,any way u could make the item u want to focus first item in ur forms design time where cursor should focus.
If for any other reasons not possible u could use in :
When-New-Form-instance or when-new-block-instance Trigger
Go_item('item_name'); the built-in
Hope this solve ur problem..
Best Regards,
Abdetu..
