OS Authentication Is Not Working For Oracle 10g Database
Sep 10, 2013
We are facing an surprising problem in oracle 10g database. Previously we are able to connect our Oracle 10g database using os authentication with "sqlplus / as sysdba" command. Last wednesday in our linux server maximum number of processes have overflowed and we need to increase the soft limit of our linux server. After that without restarting database every applications [OID 10g] are working fine. But, we are not able to connect with system using OS authentication. It is showing following.

I have got single sign on working via the built in LDAP Directory authentication in APEX. But at the moment this is letting everyone who is within AD log inHow can I assign role permissions to each logged in user so some users have an admin role and see certain parts of the application / pages / navigation items while editors and readers have different permissions
And also to restrict access to certain pages within the application
We have an issue regarding OS level authentication to access Oracle 11gR2(11.2.0.1) database.
Our environment - UNIX - AIX 5.3 (OS user id password is having kerberos security). Oracle 11.2.0.1 (32 bit client) installed in server 1 Oracle 11.2.0.1 (64 bit server) installed in server 2. Everything works fine when we created a general userid test_db in the database and connect through sqlplus test_db@dbname.
But when we try to use the option of OS level authentication using "sqlplus /", it throws following error and could not be connected.
ERROR: ORA-12545: Connect failed because target host or object does not exist
I have created the same OS user name in database (with external password authentication) with prefix OPS$. we have set ORACLE_SID as well.
I have oracle 10g up and running on Solaris 10, from windows I would like to connect to sql plus through windows authentication, for that I have already made sure that remote_auth = true and have created user in oracle with OPS$. But still I cannot connect.
I have the same setup but with oracle on windows server, the os authentication from windows clients works just fine.
does oracle 10g on solaris 10 supports windows os authentication?
Is it possible to use Database authentication in APEX through database link, and how?Also is it posible to read roles from users through database link?
I'm trying to connect Oracle 11g database from Oracle 9i database, by creating dblink on Oracle 9i database. But my session got hang while i perform this. Here i'm giving the steps i followed on my both the database. Here Oracle 9i database is my source db and Oracle 11g is my target db.
Following steps/setting on Oralce 11g Database

I'm looking for solutions to make real time replications from an Oracle 8i database.
For more details : - we have an existing database with Oracle 8i - we want to replicate this database: the replicated database will be used by a web application. - we need the replication to be in real-time (we wish to have the shortest lag)
For the moment i didn't find much information on the web and it seems that replication solutions for the version 8i are quiet limited.
Some more details :
- The responsible want imperatively that the web application work with a replicated database, without interacting directly with the original one. - An evolution of oracle should be done but within some years so were trying to find a solution rapidly with 8i.
I'd like to have my 11g database authenticate users against an OpenLDAP service. We'd still create accounts in the database, and do authorization within the database, but I'd just want to the user's passwords authenticated externally, against the OpenLDAP service. Is this possible? My searching through these forums and Google seems to indicate that you can do it if you run an Oracle Internet Directory (OID) service. I do not want to have to install and maintain an Oracle Internet Directory service. I'd like to do it without it.
I have a working PL/SQL function (below) that can authenticate a passed in username & password against our OpenLDAP directory. Is there any way for me to have Oracle call this function for the database user authentication? Or is there any other way for me to get the Oracle database to directly authenticate against OpenLDAP without having to run OID?

Data Base Configuration assistant for create new database not working in oracle 8.1.7 in windows server 2000 / server 2003 how can i create new database
At the moment, we were loading the file in our system serially. This is a very old and established system.We would like to incorporate parallel loading for our loaders to load data into the database.
Most of the issues would be due to multiple inserts happening due to the files being loaded in parallel. For some reasons, we cannot give regular commits untill the entire batch of items is processed in case the process needs to rollback. A file can contain different set of batch of items clubbed together for loading.
The issue here is untill the first file finishes loading and commits, the second file would just hang. In fact, mulitiple files might hang for the first file to finish. what can I do to overcome this?I tried to used "lock table t1 in SHARE ROW EXCLUSIVE mode nowait". When the leading process is doing inserts, the failing process will fail with a resource busy and acquire with NOWAIT specified. We would catch this exception and redirect that batch to an error file to be reloaded at a later date.
I know how to use database links in various forms, but I've been trying to think through how the authentication works for a connected user link in 11g. If I create the link like this,
create public database link using 'orcl';
then any user can use the link, provided they have an identical username/password in the two databases. With pre-11g passwords, it was understandable: the password was salted with the username, so the hash of the password would be the same in both databases, and I assumed that the logon through the link used some sort of IDENTIFIED BY VALUES mechanism. But in 11g, the salt will different in the two databases. So the hash will be different. And of course Oracle never stores the actual password. So I don't see how the authentication works.

I have oracle database server set with Windows NT authentication. How can I get rid of this kind of authentication as this is holding up additional Windows Domain with its own PDS and so on. Or is it possible to move Oracle Database server to a different Domain and authentication to be coming from new domain?
I have been using oracle based database security but company now wants to handle with windows authentication.I have windows os 2008 R2 and oracle 11.2.0.3.
I also have set up the SQLNET.AUTHENTICATION_SERVICES= (NTS).I created user with create user "domainusername" identified Externally! but now how can i connection from application to database!
I am using SSO login for Authorizations. Would like make use of SSO for creating authentication schema. My main requirement is to assign privilege based on users using SSO loging.

I have two tables : oa_membership_dtl(in this created_by field is varchar2(200 byte) ,oa_partner_usr_dtl(in this table partner_userid is number(8,0) i need to do join on above fields.
I am using following two queries:
select * from oa_membership_dtl membership join oa_partner_usr_dtl partner_user on to_char(partner_user.partner_userid,'9999')=membership.created_by select * from oa_membership_dtl membership join oa_partner_usr_dtl partner_user on rtrim(ltrim(partner_user.partner_userid||' '))=rtrim(ltrim(membership.created_by))

following is a query which i find difficult to understand why EXISTS is failing. There are two scenarios where if i block LINE 30 and unblock line 31 of the code then one record is returned.
I have an oracle package that i am using to search for a string in a blob entry. I compiled the package and the package body in one environment, it had no errors, when i execute, i get my results.I went ahead and created the same package and function in another environment and it fails by giving me the below error
ORA-06503: PL/SQL: Function returned without value ORA-06512: at "SYSTEM.IMPACTUS_PCODE", line 158 for sysadm
I have used this on other environments often and have never had an issue.
but unfortunatly the ESB that we are using uses a jms component which seems to only be able to take mono-consumer queue.So we have created our queue usuing the following
This therefore permits us to have a queue/queuetable which pushes data to a single consumer.The probleme comes when we try to add a table rule using the following command:
CODEORA-06512: on line 2 24039. 00000 - "Queue %s not created in queue table for multiple consumers" *Cause: Either an ADD_SUBSCRIBER, ALTER_SUBSCRIBER, or REMOVE_SUBSCRIBER procedure, or an ENQUEUE with a non-empty recipient list, was issued on a queue that was not created for multiple consumers. *Action: Create the queue in a queue table that was created for multiple consumers and retry the call.
We are able to create the capture rule without any problem but without the apply rule, nothing seems to end up into the queue table.AQ is not a viable solution since it is troublesome when it comes to deletes and mass updates.
A deadlock among DDL and parse locks is detected.This deadlock is usually due to user errors in the design of an application or from issuing a set of concurrent statements which can cause a deadlock. This should not be reported to Oracle Support. The following information may aid in finding the errors which cause the deadlock:
ORA-04020: deadlock detected while trying to lock object MV_LOTS
I'd like to talk about some interesting behaivor with Oracle RAC load balancer.We have Oracle RAC 11.1.0.6 - 2 nodes.
We noticed sometimes the number of sessions { select count(1) from v$session; } was not divided equally between nodes. Also load average was very different between node #1 and node #2.Now we define service explicitly.
srvctl add service -d MYORCL -s MYSERVICE -r MYORCL1,MYORCL2 srvctl config service -d MYORCL -a MYSERVICE PREF: MYORCL1 MYORCL2 AVAIL: TAF: NONE
After we change connection string of corresponding application(s) the spread will be more equal:
select service_name,inst_id, count(*) the_qty from gv$session where service_name = 'MYSERVICE' group by service_name, inst_id
Although it's not round robin algorithm, the distribution looks more equal. It seems explicitly defined service of Oracle RAC has better load balancing approach comparing to the default service (created with db by default).
But there is some downside with more 'equally' distributed load balancing. Consider a client program that is running the following SQL once a 5 minutes:
select ... from A inner join B on ... inner join C on ... inner join D on ...
where the tables B, C and D data is changing all the time.Once load balancing is distributed more 'equally', the query above will arrive to node #1 and to node #2 more equally. It will cause more interconnect traffic, because Oracle RAC will need to synchronize requested blocks all the time, with much high rate.
I have a query which returns a nested table as a result of split function. I used any method to unnest the data. But I couldn't. I try it with this query.Note: To run the following query I attached everything needed.
-- This query gives very strange results. SELECT * FROM ( SELECT
