We have audit logs of a transaction in audit files, however we do not see any changes in the table that the transaction affects.We use point-in-time recovery and flashback feature to figure out the changes in the table . DML Audit Granularity is "ACCESS".The transaction is java application transaction and we use hibernate.
How can this be possibble?
Data Type Consistency CASE and Decode
CASE expects data type consistency, DECODE not expecting.
Obviously both functions handling data types are different let it be
SQL> select decode(2,1,1, 2,'2', ' three' )"RESULT" from dual;
RESULT
---
2
SQL> select case 2
2 when 1 then 1
3 when 2 then 2
4 else 3
5 end "RESULT" from dual;
RESULT
2
SQL> select case 2
2 when 1 then 1
3 when '2' then 2
4 else 3
5 end "RESULT" from dual;
ERROR at line 3:
ORA-00932: inconsistent datatypes: expected NUMBER got CHAR
know cause of error here????I mean " every time case exp checking data type consistency"
my thought is
I am trying to get same output but different methods. Yes, clearly states this is one of the Oracle bug!
I want to know how oracle handles here ???? i mean 3rd query.Purely i am testing this function with dual(dummy) table...
obviously, no possibilities for different data type.next one i am not sure about Oracle compares int variables to int variables, char variables to char variables,
I think so .... that's why oracle throws error. am i right ??ORA-00932: inconsistent datatypes: expected NUMBER got CHAR
see this query
SQL> select case 2
2 when 1 then 1
3 when '2' then 2
4 else 3
5 end "RESULT" from dual;
// clearly i am stating what's error on 3rd line ?????Even if I refer reference books some concepts are blind to understand.
By default the Oracle utility expdp will not guarantee data consistency for particular point in time when the dump was taken.
When importing such dump you can get errors like
CODEORA-39083: Object type REF_CONSTRAINT failed to create with error...
ORA-02298: cannot validate (...) - parent keys not found
To make your Oracle data pump dumps consistent use flashback_scn or flashback_time option.
Example:
CODEexpdp myschema/... DIRECTORY=expdp_dir DUMPFILE=mydb_20110308.dmp logfile=mydb_20110308.log SCHEMAS=myschema FLASHBACK_TIME=\"TO_TIMESTAMP\(TO_CHAR\(SYSDATE,\'YYYY-MM-DD HH24:MI:SS\'\),\'YYYY-MM-DD HH24:MI:SS\'\)\"
Data Type Consistency CASE and Decode...CASE expects data type consistency, DECODE not expecting.Obviously both functions handling data types are different..let it be
SQL> select decode(2,1,1, 2,'2', ' three' )"RESULT" from dual;
[color=red]RESULT

SQL> select case 2
2 when 1 then 1
3 when 2 then 2
4 else 3
5 end "RESULT" from dual;
[code]...
I am trying to get same output but different methods. Yes, clearly states this is one of the Oracle bug! Oracle compares int variables to int variables, char variables to char variables, If any discrepancy between the two data types, then the query will fail but here not different data types.
Even if I refer reference books some concepts are blind to understand.
AVDF current version 12.1 not support External/SAN storage. my question is, if customer get a huge number of Audit log and DBFW event records, then how max size can Audi Vault server support for online data (not archive data)? and can I use a Hardware server with multiple HDDs for AV Server?

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))
by using first data is not fetched but 2nd is working fine , i am getting the matched records using 2nd query.
whats the diff between to_char and || symbol?

I got many times oracle ORA-00494 error and the database went down but since 29th of july the database have not been killed.
The error message is below :

My database is used for datawarehouse of many terabytes.
Initially the redo log size was 500Mbytes and I've set it to 3Gbytes. The maximum log switch is after 5 minutes. I want log to be switched every 20 minutes or every 30 minutes.
To obtain the size of redo logs I've executed this query :
SQL> select OPTIMAL_LOGFILE_SIZE from v$instance_recovery;
OPTIMAL_LOGFILE_SIZE
--------------------
54763
53,5 Gbytes is it not very big as redo log size? What's the maximum size of redo log? To set very big redo log size what are the requirements? Which precautions should I take before? What are the risks? Are any other ways to change the log switch frequency?
I am using Oracle 11.2.1.0 version.I want to restrict archiving for some tables. I think NOLOGGING will solve this problem. Is there any option for restricting archiving.
For example, I have three tables called A, B and C. I want to archive only 2 tables A and B but not C.
I have one requirement saying that " Can we restrict archive logs for some tables".

We can audit a particular table alone, I would like to audit one table, to find all different kinds of queries fired (Including select, insert and update) over a period of 2 months.
View 4 Replies View RelatedI am trying to create materialized views based on a few tables in a logical standby database.
The target database (11g R2) where the MVs will be created is a stand-alone database.
The DB where the base tables reside is a logical standby database (11g R2).
The requirement is to do a "FAST REFRESH" of the Materialized Views.
My questions are :
1. Can I create MV logs in the logical standby DB?
2. If the answer to question no. 1 is "Yes", do I need to do anything different or configure the logical standby DB in a specific manner in order to create MV logs. From what I understand, the objects in the logical standby database are in a locked state.
Assuming you have a 9i database . where you have it enabled in archive mode , yet constantly deleting the archived redo logs , due to space constraints .
Will you be able to perform a full level 0 backup , and the following incremental backups , in the absence of the archived redo logs ? And are these incremental backups enough to recover the database or particular data files , to the point of the backup itself at least ?
Is there a way to automate deletion of applied archived logs after rollforward?
I'm thinking of crontab, and a script referring to the alert log to get the archived log filename.
Setup:
OS: HP-UX B.11.31 you ia64
DB: Oracle 10g 10.2.0.4.0 (mounted)
I'm currently working on a project in which I do not have permissions to access the Server where the database is installed and configure.Because of company policies, I do not have Admin Rights over Oracle, but I do have an account that can make Selects to DBA_USER_PRIVS for instance.
I would like to know if there is any way to access the database logs to know if there was any kind of problem within the database, because one of my Schemas misteriously went clean (all tables, sequences, triggers, ... vanished)
I have Sap r/3 system which runs on Oracle 9 database. The problem is that the sql queries produces an awful lot of logs thus my disk is full after very short time.
I do not need the logs since its development environment. Are there any tools that erases the logs automatically?
i have a sequence for one of my table that this sequence's current value was 3000 yesterday but today when i checked current value of it, i surprised because the value changed to 50, can i check who changed my sequence? is exists any data dictionary that shows logs of modified database objects.

We are in the process of setting up our backup policy. After the Archived Logs have been backed up, we need to delete them after 7 days. Also the actual files on disk.
RMAN does not delete the Archived Logs from disk.
I always find difficult to understand the alert logs and other log of cluster as well so i am wondering what to read for . do i need operating system knowledge or oracle architecture knowledge or some concepts or ?. as i saw many experts and even normal dba always talk about read logs and they are quite technical so how can i achieve to understand these logs completely
View 1 Replies View RelatedI have to create a audit/history table on a master table so that I can store the old/current state of data in my audit table. I am planning to write following program.
1. Created the audit table with similar number of records.
2. Everyday at a particular time I will compare the audit/main table and push the records in audit table which are either updated or not present in the audit table so that the audit table = main table + old state of data.
I am unable to figure out the proper way to implement the point 2 above in oracle database.
I need to list all AUDIT command issued.I'm using the DBA_STMT_AUDIT_OPTS view, but it doesn't list all of them.
For example if a run this command:audit create session by my_user;
the DBA_STMT_AUDIT_OPTS will list it. But if I run this command:audit select on my_user.my_table;
The DBA_STMT_AUDIT_OPTS list only the first.
Why the DBA_STMT_AUDIT_OPTS doesn't list the second audit command?How can I track all the AUDIT commands issued?
how to set up alerts on specific audit log results without using Audit Vault?
