I am trying to create a new user from Oracle SQL Developer. I made a connection with the user Sys and the password that I entered in the installation of Oracle Database XE 18c.
When creating the user I get the error ORA-65096, I have searched the internet and the solution I found is to write the following:
alter session set "_ORACLE_SCRIPT" = true;
However, I want to know if it is possible to create the new user without using any SQL statement or script and do it from the Oracle SQL Developer interface, do I have to login with a different user than Sys to create a new user? or what do I have to do? Could someone give me a detailed explanation please. I am learning how to use this database and I want to try to understand what I am doing.
oerr ora 65096
65096, 00000, "invalid common user or role name"
// *Cause: An attempt was made to create a common user or role with a name
// that was not valid for common users or roles. In addition to >the
// usual rules for user and role names, common user and role names
// must consist only of ASCII characters, and must contain the >prefix
// specified in common_user_prefix parameter.
// *Action: Specify a valid common user or role name.
This implies that you are connected to the root container instead of to a regular plug in database (pdb) where applications should be built. The solution for you is not to overrule setting to enable building an application in the root container but to connect to the pdb that has been made to host your application.
you can check the available pdb's by viewing v$pdbs. The special pdb cdb$root is as the name already tries to tell, the root container. show PDBS will give similar output.
Using alter session set container = [pdb_name]; can be used to switch to your container of choice where regular rules apply.
Even better is to directly connect to that pdb using sqlnet.

My company has a database for vehicle tracking system. And It has a website for user to log on and use.
After I change the sys and the main user password through "ALTER USER --- identified by' command. The website login became dysfunctional. Our DBA just quit so I have no idea how to troubleshoot.
Is there any guideline I can use?
It appears as though the application has the passwords either hardcoded or in a configuration file somewhere. If you can find where that is, then simply changing the corresponding values (ie passwords) should resolve the problem. If that doesn't work, you can try to change the password back to the what they were before using the same syntax you used to make the initial change ... "ALTER USER --- identified by ...
Can possibly be more help if you can tell what web server is hosting your site.
I'm just getting started with Oracle data export and import and things worked perfectly fine the first time around. But then I came back next day repeated the exact same steps on the same systems, but get ORA-01435: user does not exist error.
System Specs for all machines:
-OS: Windows 2012 R2 x64
-Oracle Server: Oracle 11G Express x64
Objective:
I'm exporting data from Oracle server 1 and importing to Oracle server 2.
Procedure:
Export data dump is successful from Oracle server 1.
but when importing the data dump on Oracle server 2, I follow this procedure:
-Stop IIS service
net stop WAS
Create Schema/user account and Grant privileges before import
net stop WAS
sqlplus / as sysdba;
CREATE user PIE1 identified by PASS1;
GRANT ALL PRIVILEGES TO PIE1;
GRANT IMP_FULL_DATABASE TO PIE1;
According to oracle, all goes well, but look at the first image bellow. In DBeaver, I can see that only the User account PIE1 has been created, but NO schema.
Oracle issue 1. User account created, but not the Schema
Question 1: According to Oracle, the command "Create User" IS supposed to also create an associated Schema. Anyone have an idea why this is no longer working for me? It worked once the night before.
I then continue the import procedure as follows:
imp PIE1/PASS1#xe file=c:\Backups\AVUSER2_6_7.dmp log=c:\Backups\import.log fromuser=AVUSER2_6_7 touser=PIE1;
But get the following error:
Oracle claims the User doesn't exist even though it does
Oracle claims the User doesn't exist even though it does. I repeated the entire procedure and even created an identical import/export user account and credentials, and this error still comes up.
Question 2: Any idea why Oracle "Can't find" a user account that's clearly in the database?
Additional Info:
Checked that my windows account is in admin group
Checked that my windows account is in ORA_DBA group
Opened all CMD prompt as Admin
As you implied, users and schemas as the same in Oracle, you can't have a user without a schema. No idea about DBeaver, but as there are other users that aren't listed under 'schemas' (according to your second image - ANONYMOUS, DIP, ...) that seems to be unrelated.
(Purely a guess, but perhaps the user you're connect as in DBeaver just doesn't have visibility of any objects owned by those users - maybe it only lists users it can see in all_objects, say. Pure speculation, but you could investigate that by looking at the data dictionary while connect through SQL*Plus as the same user. According to this old forum post, there is an option to hide empty schemas...)
The import is connecting successfully as PIE1 - you'd get a different error, ORA-01017, if it wasn't and you wouldn't see the 'Connected to...' banner or anything after that.
Your import command has a trailing semicolon that should not be there. The "importing ... objects into" message shows that it's trying to import into the PIE1; user and not the one you actually created, PIE1. Remove that semicolon and try again.
Incidentally, you can probably also remove the #xe TNS alias and stick to a local connection, assuming the environment is configured as it was whenyou ran SQL*Plus. You should also consider using datapump expdp/impdp rather than the legacy exp/imp.
I have created a db link AM_ADMIN through SQL Developer:
I am trying to check if it is a valid database link. When I test it from the SQL Developer wizard it is successful. But when I use the below command:
SELECT * FROM dual#AM_ADMIN
I'm getting the error:
ORA-02019: connection description for remote database not found
How can I rectify this error?
According to your screenshot you created the database link as AM_ADMIN.INT.xxx. You are calling it without the domain, just as #AM_ADMIN. Unless you have a sqlnet.ora which defines names.default_domain with the same domain value (and have SQL Developer configured to recognise that), you will need to fully-quality the link name when you use it:
SELECT * FROM dual#AM_ADMIN.INT.xxx
This error will occur when a database link is not made PUBLIC, and the user who created the link is different to the user attempting to use the link. For example, creating the link as the SYS user and then trying to use the link as the AM_ADMIN user.
In this instance either make the link PUBLIC (which all users can then access), or grant the AM_ADMIN user the privileges to create a database link.
I had the same problem and I found out that it was a stupid error caused by (Description = (... HOST = !...). When you create Database Link in USING clause, you should:
use the keyword HOST if you are using the IP address
use keyword HOSTNAME if you are using the name
I just wanted to share it because I lost half a day trying to figure that out and I couldn't find any information about it...
I've been starting oracle on my job. But i've been using MS all the time. Now i have problem on User-Shema structure. I tryed a create table with sql query, but table had been created in somewhere else then i wanted. (I've already created a user named LPA) I just wrote the query, and table is in the (GeneralDatabase) Tablespaces->Users->(Here). I want to create a table in LPA schema, under the table folder. I've been searching for it but i could'nt get it. So need some help please.
PS:I found that i need to connect with user, than write to query with TS_LPA(Thats my tablespace). But i also cant connect with the user LPA.(We can say this is my first problem)
In Oracle there is no "dbo" or default schema, in case that is what you are looking for. You must specify the target user account when you connect (log in) to the database, and that account will be used as the default schema for all of your subsequent actions. (This is similar to a home directory in Linux, where if I log in as williamr and create a file, it will belong to williamr and not some generic default account.)
In your case I suspect you are connecting as SYS or similar, in which case your table now belongs to SYS (or whoever you are connected as). You'll need to drop it and try again.
If you don't want to post the connect string you used to connect initially for some reason, then execute the following query to see your current schema:
select user, sys_context('userenv','current_schema') from dual;
(Normally user and sys_context('userenv','current_schema') will be the same, but worth double-checking.)
In PL/SQL Developer you can only issue connect commands from a Command window (not a SQL window). Alternatively you can use the 'log on' menu tool, or Session > Set Main Connection from the menu, or (best if you want to reuse it later) Tools > Define Connections, which has a 'Test...' button to validate a new connection. You'll need the username, password and database service name (not just username and password).
connect with LPA user.
specify the schema name before table name.
create table LPA.tbl_name(col1 datatype1,....);
I want to create the user and the database within that user. But when I tried to create database its giving the warning message as
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-01100: database already mounted
Then I tried
STARTUP NOMOUNT;
Its giving the warning message for insufficient privileges even I have given all the permission to that particular user.
Can any one please help in finding the solution for this?
You don't create a database under a user in Oracle; I believe you're using terminology from another database poduct. The equivalent is a schema, which is a logical container for a group of objects. User and schema are essenentially synonymous in Oracle - when you create a user is automatically has its own schema.
You create the database once (which you already seem to have done, or had done for you), then create as many schemas/users as your application needs. You don't ever rerun the create database under normal circumstances - you certainly wouldn't as a normal user.
If you connect as that user you will be able to create tables, views, packages etc., assuming it has really been granted all the necessary privileges.
