I have question regarding data masking. Currently we are using Oracle 11g database , we are thinking of implementing data-masking feature in 11g. Is this can be done by adding any package to it.

Is it possible to add two unpivots in a single UNPIVOT query.
Questions about implementing ARCHIVELOG mode in RAC environment.
Oracle 11gR1 RAC + ASM database. I'd like to implement ARCHIVELOG mode. Each node will have its own archive log.
Does it make sense to place archivelogs on ASM (shared storage)? Or the best practice would be to have some aside "BACKUP" server to place and keep archivelogs from all the RAC nodes there?
Additional question is about archive logs space required estimation. If it's correct to know estimate archive logs space required to get the daily avg number of switch logs
CODEselect round(avg(n_of_switch_logs), 3) avg_num_of_switch_logs
from (select trunc(first_time), count(*) n_of_switch_logs
from gv$log_history
group by trunc(first_time))
and multiply it on size of single redolog?

View 1 Replies View RelatedWe are planning to use an Application Express application for intranet and internet users. We want to implement a DMZ configuration for this application.
Is there any good guide to implement it?, we want to use Oracle Http Server to access Oracle Application Express.
we are implementing case insensitive seaarch in our small 10g database...We would be modifying the following parameters.
nls_comp=LINGUISTIC ;
nls_sort=binary_ci;
We want to use the existing indexes and as I understand we will need indexes created in following manner
create index <index_name> on <table_name>(nlssort( <column_name>, 'NLS_SORT=BINARY_CI'));
1) Is there any mechanism with which we can convert existing index to above type? (without drop and recreate)One of the issue I can see is related to unique values as 'ABC', 'Abc' and 'abc' would be treated same
2) Apart from that is there any issue, added maintenance for such index?
I'm writing a VPD function to be used for column masking. The predicate (WHERE-clause) it generates may take many different forms. In particular, it may contain inner-selects; for example,
"exists(select '*' from B where B.VAL = '123' and A.KEY = B.KEY)"
where A is the table that is associated to the VPD function, and B is some other table.
if this is OK for column masking? If not, my VPD function may sometimes work and sometimes fail, in unexpected ways.
The Oracle Database Security Guide (11g Release 1) says
Column-masking conditions generated by the policy function must be simple Boolean expressions, unlike regular Oracle Virtual Private Database predicates".
This seems to indicate that there are cases where a VPD function works for row-level security, but not for column masking.
an example of a 'regular Oracle VPD predicate' that doesn't work for column-masking?
I just want to know whether we can mask salary column of number datatype into text ,like we used to_char(to_date(<column_name>,'j'),'jsp') in sql? for example
Name Salary
SMITH 800
to
Name Salary
SMITH EIGHT HUNDRED
I want to understand the restrictions that apply to VPD functions when used for column masking, compared with their use for Row-Level Security. According to the Oracle Database Security Guide (11g Release 1) Column-masking conditions generated by the policy function must be simple Boolean expressions, unlike regular Oracle Virtual Private Database predicates.
I have long understood the above as implying that column-masking conditions should not contain sub-queries (i.e. inner selects). However, we tested using a condition with a select inside another select (2-level nesting) and yet it worked. We were on 11g Release 2, by the way. So, I wonder about using sub-queries in column-masking conditions? Or, alternatively, what Oracle means with "regular VPD predicates" and "simple Boolean expressions" (of course, in the context of VPD)?
I am looking for Masking options/techniques to mask few columns. I am aware of the option Oracle Data Masking Pack. But its costly.
View 6 Replies View RelatedI got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site

View 7 Replies View RelatedI am planning to use Data Guard facility in Oracle 10g database.
1) I would like to have a standby database, which can be used if the primary goes down and also for reporting and other queries (read-Only).
2) What is the difference between Physical and Logical standby database. I have to explain non-technical users (management) regarding this.
3) What is Sync and Async redo log apply?
4) When i manipulate data (Insert,Delete,Update) in logical standby database, will these changes reflect in Primary database synchronously?
5) Which type of REDO APPLY is better: Managed Recovery Process(MRP) or Real Time Apply(RTA)?
6) can the redo data be deleted if its obsolete or is it deleted automatically by oracle?
7) If i want to take backup, should i take it from primary or standby database? If standby, then the database should be in which mode (Read-only or Recovery Mode)
I am working on informix 7.25SE version I need to import data from informix to oracle 10g data base .
View 5 Replies View Relatedi have done oracle data guard between two databases (database A is the primary) and (database B is the standby), and it was working fine for two weeks, then the network admin did some changes on the firewall on standby side, which made the primary database can not write on standby redo log , so archives was generated on primary and do not generated on standby by, now we solve the firewall probelm and new archives generated on primary is generated on atandby too, but now i have a gap in archives on standby database and standby database now is not synchronized with primary database, and data changes happen on primary is not reflected on standby, also archives that were generated on primary and did not generated on standby during the problem time is not registered in V$ARCHIVED_LOG neither on primary database nor on standby database

how to mask data in oracle 11g database release 1
my environment is
Database: 11g release 1
os: AIX 6 (64 bit)
GC:10g release 1
it is possible to have a oracle database that stores data in different languages.
I have gone through few blogs which says Oracle supports Unicode characters & UTF8 supports all languages including multi-byte.
I would like to know what are the languages supported by oracle 10G.
Oracle database version is : 10G.
When we try to query a column from a table the output is shown as "?????". Seems the data in that column is stored in a different character set, which is not recognised while displaying the output. The column size is 35byte.
The nls parameter table shows the character set as "we8mswin1252".
get this issue resolved.

View 4 Replies View RelatedI'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production and TNS for Linux: Version 11.2.0.3.0 - Production.Requirement is to create a script to add a LIST partition to some selected tables in a schema (tables do not have data, they are not partitioned). There are about 300 such tables (can vary) and their names are maintained in a separate table. Example -Existing table
-CREATE TABLE test_part(id number (2),
name varchar2(20),
audit_userid number (9));
Expected table
-CREATE TABLE test_part(id number (2), name varchar2(20), audit_userid number (9))
PARTITION BY LIST (audit_userid) (PARTITION p1_audit_userid VALUES (1));
Ultimate goal is to add more partitions based on the amount of data to be populated.
I have a serious doubt in oracle architecture functionality, when a user issues a update statement the data blocks are carried to db buffer cache and where does the changes to the data blocks are made???? Does a copy of the data block is kept in db buffer cache and the changes are made to the block in buffer cache?? or the a copy of the data block is kept in undo tablespace and changes are made to the blocks in the undo tablespace???
In simple the changes to the data blocks are made at db buffer cache or undo tablespace?
I'm trying to create a physical standby database on my Oracle9i DB runing on WinXP.
Note: I have both Primary and Standby on the same system.
Actually everything went well .... I did created the standby DB but the problem is I can not start my primary DB if my standby DB is mounted. I get this error:
ORA-01102: cannot mount database in EXCLUSIVE mode
And when I read about the error message I learnt that I should start my DB in compatible mode ...
I want to Copy a data from One oracle database to another.
I have checked Import/Export Utility but the problem is import utility doesn't support conflicts resolution techniques between rows.
For Example if there's a table in the source database have the same row key in the destination database. if i use 'Ignore' parameter with value = y, the destination table will have a duplicate rows.
I want to ask if there's another way to import data from oracle database to another with some mechanism of detecting the conflicts and resolve them?
