Server Administration :: Oracle Database Server - Logon Denied
Jul 19, 2011
I am connected as System. It was the only user I set-up a password when installed the database on personal computer.
SQL> alter user sys identified by mypass007

User altered.
SQL> connect sys/mypass007
ERROR:
ORA-28009: connection as SYS should be as SYSDBA or SYSOPER
we have an application that is running from remote host to connect database using JDBC driver 10.2.0.2
but i am getting ORA-01017 error intermittently. we fetching stored username/pwd after every 5 min but for certain interval it's giving error and we get connection sucessful after some time with same username pwd.
the application monitor more number of databases but facing problem with only 1 instance.
-I have a Oracle Client 11.2.0.1 (*Administrator*) installed on a client machine on Redhat 6. -I have a database 11.2.0.1 testdb installed on another machine.
I configured tnsnames.ora for the client machine to connect my database testdb.If I use sqlplus to connect to the testdb from client machine, it's successful.However, If I use one of the jdbc connection string from the client machine, it reports "ORA-01017: invalid username/password; logon denied"
Case 2,
-I have a Oracle Client 11.2.0.1 (*Runtime*) installed on a client machine on Redhat 6. -I have a database 11.2.0.1 testdb installed on another machine.
I configured tnsnames.ora for the client machine to connect my database testdb.
-If I use sqlplus to connect to the testdb from client machine, it's successful. -If I use one of the jdbc connection string from the client machine, it 's successful too.
For case 1 and case 2, the only difference is the Oracle client (one is Runtime, the other is administrator)The database I have is set to
SQL> show parameters case
NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ sec_case_sensitive_logon boolean FALSE
I have a log-in problem. I created the new database and when I try to log-in with system user, its giving ORA-01017: invalid username/password; log-in denied, and when I try to log-in with "/ as sysdba" its successfully logged in.
When I try to change SYSTEM user password, I successful change and connecting and after few seconds when I try to connect its again giving same error "ORA-01017: invalid username/password; log-in denied
i am trying to install Oracle 10.10.2.0 on Windows Server 2003 standard x64 Edition Service Pack, but when i try to run the installer or open DVD it gives me below error.
"The image file D: is Valid, but is for a machine type other than the current machine."
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server. 2. I invoked "sqlplus" from another unix box to login to the database. 3. I found that the process id (ps -ef |grep sqlplus). 4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID, SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM, SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID FROM SYS.GV_$PROCESS, SYS.GV_$SESSION WHERE SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST' and SYS.GV_$SESSION.MACHINE like '%hostname%'
I recently installed Oracle 10g on my windows Xp laptop. It has become considerably slow since then. I want to start the database server only when I need it, and not every time I start my laptop. I looked around in OEM and did found a way.
"ORA-01017: invalid username/password; logon denied" when attempting to log on to db, in three different applications. Error is observed in Toad, Crystal Reports, and MS ODBC Administrator connect test. However, same db credentials work in SQLPLUS.
Customer is attempting to log into reporting database hosted by my company, and using Cisco VPN client.I am unable to reproduce this at this time, on my machine, using same credentials and VPN profile.
Here is what we know/tried:
1. PING HOSTNAME is successful on CUSTOMER’S machine
2. TNSPING HOSTNAME is successful on CUSTOMER’S machine
3. SQLPLUS is successful with USER2/(pw)@HOSTNAME.int on CUSTOMER’S machine
4. We corrected timeout error on CUSTOMER’S side, by adding TCP.CONNECT_TIMEOUT=1000 in SQLNET.ORA (Also observed extremely slow performance on CUSTOMER SIDE)
5. We corrected dns suffix problem on CUSTOMER’S side, observed in NSLOOKUP by adding: IP ADDRESS AND HOSTNAME to Windows HOSTS file and commenting out default suffix COMPANY.com from SQLNET.ORA file
6. VPN configuration and VPN credentials are good.
We tested CUSTOMER’S VPN profle, CUSTOMER’S VPN credentials, and user USER2/(pw)@HOSTNAME on my machine (WIN7). I am able to maintain persistant connection to HOSTNAME for hours
7. TNSNames entries are good. Able to connect to db in Toad, and Crystal, on CUSTOMER’S machine using different Oracle user, USER3 (only has grant connect). Unable to logon to db, with Oracle user USER1, or USER2. (USER2 was created to try to resolve login problem w USER1, but issue still exists.)
8. CUSTOMER has Windows VISTA, does not have admin privileges, has Oracle 10 installed for client. Using same Cisco VPN client I have installed.
I have some requirement wherein I need to install Oracle 9i database server (9.2.0.7). I am not getting it on Oracle website. where can I get the download.
I have installed oracle 10g software and created Database on RHEL 4. when i run the run.sql its successively done but im not getting tables. whats the prob.
installed and configured oracle 12.1.0.1.0 on linux and i noticed there is no emctl? I went through the oracle docs and i see no references as what to use,
I am trying to upgrade the oracle 9.2.0.8 database in oracle 11.2.0.2. I have installed the new oracle home for 11g and after running the pre-upgrade script and setting the all environment variable like oracle base, oracle home, oracle sid and ora_nls
i am running the dbua but after click on finish button it's do the processing of 2% but after that i get ------------------------------------------------- ORA-12709 error while loading create database character set --------------------------------------------------
I have oracle 10g running on oracle ASM 11.1, I want to know that if i install oracle 11gr2 database , can i use oracle 11.1 ASM which is already installed ?
I installed Oracle 11g and created a test database in that the default count should be 4196... but it is 4143.. some packages are missing.. even when i'm creating materialized view it is showing some error that packages are missing. what can i do for that? Is my oracle s/w corrupted ? even when i downloaded from oracle site it also shows the same count.
Database Connection failure. Reason: java.sql.SQLException: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist SVR4 Error: 2: No such file or directory
I'm not an Oracle expert, but I have research a little and seems that the SID could be wrong or that the DB is down, in fact I have already checked trhe server but everything seems normal to me.
Yesterday i installed oracle 11g r2 by default i installed database Oracle with the installation .but today i tried to create the database with the name green tat also completed successfully..the problem is in startup
export oracle_sid=green sqlplus '/ as sysdba' startup database mounted
select instance_name from v$instance; But it SHowing the instance name as Oracle...i tried with the other method also
export oracle_sid=green sqlplus /nolog conn sys/b123 as sysdba
database mounted
select instance_name from V$parameter;
and it shows instance name as green..i tried to see the datafile location for green database
select file_name from dba_data_files; it shows the orcl datafile locations.
When I try to log into my db with a specific user I get this message. Below is from the alert log. I can login as system just fine.
----- Error Stack Dump ----- ORA-00604: error occurred at recursive SQL level 1 ORA-01438: value larger than specified precision allowed for this column ORA-06512: at line 2 Oracle 10g OEL 5.5
How to enable firewall for Oracle Database..? Is it db specific..? or If I implement the firewall It will be applicable to all the databases in the server which are using same oracle home..?
Actually in our environment , sysadmins are upgrading java versions on Unix (HP & Solaris) Machines and they have asked the query whether oracle database uses Java or not?
If it uses then all the databases need to be shut down for their planned activities and if not no need to shutdown the databases.
