Oracle 11g automatic archival // maintaining historic data

Hi Group,
We are planning to get Oracle 11g.
I want to know if Oracle 11g has the capability to do automatic archival?
My requirement is,
few of the tables in our application will have lot of records (data) and after some days/ months it might slog the performance cos of the table/db size, and also the old data will not be of much interest (but data cannot be purged/deleted until some years). Hence want to archive the old data (trigger conditions specified by the user) and will be needed to bring data back programatically whenever the user queries for the data belonging to that particular period(archived data).
Is there a feature available in Oracle to just specify the data to be archive and bring it back by giving a date/time input.

Hi,
First, this looks like a job for Oracle partitioning.
What is your motive for archiving? Improved performance? Cheaper media?
I want to know if Oracle 11g has the capability to do automatic archival? Sure, but you would have to script it yourself. Many shops do time-based rollover archiving with partitioned tables:
http://www.dba-oracle.com/t_partitioned_tablespace_archiving.htm
it might slog the performance cos of the table/db sizeNo, not if you are properly indexed . . . However, table partitioning can speedup queries against large tables with "partition aware" SQL:
http://www.dba-oracle.com/t_partition_sql_index_ss_hint.htm
want to archive the old data (trigger conditions specified by the user) I would not use triggers, schedule a job instead:
http://www.dba-oracle.com/t_archiving_data_in_file_structures.htm
needed to bring data back Sorry, back from where? You are archving to disk, right?

Oracle 11g R2, Problem Loading Spatial Data

We have a geodatabase which has been implemented by oracle spatial. it has been working quite fine since 2 years ago. Recently the data center serving our geodatabase has been upgraded on both software and hardware specifications. The handler application now has difficulty retrieving spatial data. The problem is somehow strange; only some spatial objects are loaded and then application encounters exceptions.
Previous working database engine was an Oracle 11g R1 and the new one is Oracle 11g R2. The application is a java application mostly written by swing. Here is the stack trace:

I read in some forums that the problem could be caused by jdbc version incompatibility, so I just copied jdbc archives from the installed oracle 11g R2 jdbc folder but the problem persists. Last thing I should mention is that only spatial data is problemistic and non-spatial data is easily loaded.
Please Help, Thanks.

Hi storm,
During the installation of oracle as you said if you have given the global password, basically this specific password will reflect to users such as
-sys
-system
-dbsnmp
-sysman
As you are new to oracle the basics that you should know is that "SYS" user is the highly privileged user in Oracle and should be logged in as "sys as sysdba" with his respective password (i.e. the global password that you have entered during database installation) to obtain his privilege. Remember to manipulate your database with caution when you are logged in as the sys user. You can log into the database using the sys user in the following way:
c\> sqlplus sys as sysdba
password: ****** --It will ask you for the password and you will have to give the global password that was given during installation
Hope this helps!!!
Regards,

Oracle 11g Fusion Middleware Control, CGICMD.DAT

Finally, I have Weblogic and Oracle 11g Forms and Reports up and running. Now, I would like to create a Mapping Key in the CGICMD.DAT file, so that all the login information will not show up in the URL when I run a report. Can someone please tell me how to do this through the Middleware Control console? I do know that i have to go through the MBeans System to find "CgicmdConfigMXBean" but it seems like trying to find a needle in a haystack. Also, is there a specific format when creating a Mapping Key? would like to include the path, userid information for connection to the reports.
thank you,

Automatic archiving of OpenDirectory data

Hello,
I would like to be able to create a cron job to automate the archiving of the OpenDirectory data.
There is a command line tool to create an archive like the one created by the Server Admin tool? Or should I use slapcat and kdb5_util to dump the ldap data and the kerberos data, but so loose the esasy import features of Server Admin.
Thanks
Cristiano

I believe the command you are looking for is, "slapconfig -backupdb <path>."

Oracle 11g Goldengate working in a Data Guard environment

Hey Guys, I have the following setup:
Oracle 11.2.0.4.4 running on RHEL 6.6 64-bit
3 node RAC Primary
Single-node Standby with GI (Oracle Restart)
4 DBs on Primary - AA, BB, CC and DD
4 DBs running in Active Standby - AADR, BBDR, CCDR and DDDR
Databases AA and BB replicate schemas into CC, which is a Reporting/Operational Data Store. GoldenGate 11.2.x is used for the replication
XAG used for Goldengate HA
All good here with the Primary DBs and replication humming along quite nicely.
I have questions as part of building the DR environment. How should this work? As part of the real-time apply and active standby, CCDR should keep pace with the replicated primary DB CC. Now from a role transition perspective, I need to be have the GoldenGate software installed and configured on the Standby Server for starting the processes.
Question 1: When the role transition happens, based on the data guard role, I could well have a system trigger to spawn off a shell script that starts off the goldengate processes. Would this be the correct approach?
Question 2: Do I need to worry about setting/starting the extract/replicat from a specific CSN? The checkpoint table will be kept in sync as part of the SQL apply, so would just starting the extract and replicat process on the new Primary (old DR) work?
I am unable to get any pointers on this in Metalink. Would appreciate anyone could point me to a MOS document that talks about using GG and Data Guard together.
Thanks

On the first day, there is no backup to recover. It is only on the third day's run that this command will really be successful.
The white paper does explain this.

External tables in Oracle 11g database is not loading null value records

We have upgraded our DB from Oracle 9i to 11g...
It was noticed that data load to external tables in 9i is rejecting the records with null columns..However upgrading it to 11g,it allows the records with null values.
Is there are way to restrict loading the records that has few coulmns that are null..
Can you please share if this is the expected behaviour in Oracle 11g...
Thanks.

Data isn't really loaded to an External Table. Rather, the external table lets you query an external data source as if it were a regular database table. To not see the rows with the NULL value, simply filter those rows out with your SQL statement:
SELECT * FROM my_external_table WHERE colX IS NOT NULL;

Select first and last records in grouped results - Oracle 11g

Say I have the following information in an Oracle 11g table:
Qty
Production order
Date and time
20
00000000000000001
12-JAN-14 00:02
20
00000000000000001
12-JAN-14 00:05
20
00000000000000001

20
00000000000000001
13-JAN-14 00:09

12-JAN-14 00:20
30
00000000000000002
14-JAN-14 00:29
I would like to write a query that would return the following:
Qty
Production order
First
Last
80
00000000000000001
12-JAN-14 00:02
13-JAN-14 00:09
120
00000000000000002
12-JAN-14 00:11
14-JAN-14 00:29
That is, the sum of the Qty column grouped by Production order, and the date/time of the first and last records for each Production order.
I came up with a query that yielded this result:
Qty
Production order
First
Last
80
00000000000000001
12-JAN-14 00:02
14-JAN-14 00:29
120
00000000000000002
12-JAN-14 00:02
14-JAN-14 00:29
Which means that the First and Last columns show the overall first and last date / time of the whole table. Please note that this is a dummy table. Sorry I am now allowed to write the actual query
I came up with since work policies do not allow me to share it. Also, I tried with windowing functions such as rank()and row_number() but my user does not have enough privileges to do so.
Any help or hints will be greatly appreciated.

Due to the fact that Oracle does not record the rows in any particular order, it would be wrong that the "first date" would be the first row processed by the query.
Therefore you would have to supply some other column if you do not want to consider the table as ordered by date.
Also, any analytical functions will need you to supply the "order by" and if its the date, then just a simple query will do:
SQL>WITH Tab1 (Qty, Production_Order, Pdate)
2       AS (SELECT 20, '00000000000000001', TO_DATE ( '12-JAN-14 00:02', 'DD-MON-YY HH24:MI') FROM DUAL UNION ALL

Oracle 11g SGA & PGA setup

Hi I installed oracle 11g & create database , now i want to use fully optimize database.
Currently my DB server RAM is 16GB, how should i allocate SGA for this.If i used oracle 11g automatic memeory management feature to allocate SGA+PGA, how should i use them.Currentlymy SGA is set to 4GB, Please advise

Hi,
It is depends upon the workload which you have in your organization(future and present situation)
SGA+PGA size will be automatically managed by Oracle. No need to worry about this.
If you need to increase Memory_Max_Size, you can also increase the Memory size in the future.
Thanks

Oracle 11G/ MV log is newer than the last full refresh

MV log is newer than the last full refresh / MV-Log ist neuer als letzter vollständiger Refresh
Oracle 11G
We access from two data banks about MATERIALIZED VIEWs a big master table.
The second data bank is new created. A Complete-Refresh lasts > one hour.
Then never takes place fast-refresh because the MV log on the master db
does not reproach with the data long enough. What can we do? Can one
increase the hold duration of the data in the MV LOG?

or ml.master is null
or ml.master = :mastertable
order by 1,2;For :mastertable you have to insert the name of the table, where you created the MV LOG on.

"Database log mode" & "Automatic archival"

I was asked to do the below
"Database log mode" should be set to
"No Archive Mode" now.
Do not mix up "Database log mode" with
"Automatic archival".
Can you please tell me how to "disable databse log mode", with Automatic Archival enabled.
Regards,
Susan

From documentation:
ARCHIVELOG mode
The mode of the database in which Oracle copies filled online redo logs to disk. Specify the mode at database creation or by using the ALTER DATABASE statement. You can enable automatic archiving either dynamically using the ALTER SYSTEM statement or by setting the initialization parameter LOG_ARCHIVE_START to TRUE.
Running the database in ARCHIVELOG mode has several advantages over NOARCHIVELOG mode. You can:
* Back up the database while it is open and being accessed by users.
* Recover the database to any desired point in time.
To protect the ARCHIVELOG mode database in case of failure, back up the archived logs.
Configuring ARCHIVELOG Mode For the Database<a>
 
Or you can check this tutorial from Oracle:
Disabling Automatic Archiving
 
 
Or something like this: 
sqlplus /nolog
connect / as sysdba
shutdown
startup mount exclusive
alter database noarchivelog
alter database open
 
And I don't know if it's needed to have automatic archival enabled since the database will not be in archive mode.

How to backup flashback data archive enabled tables -oracle 11g?

1) Whether the flashback data archive can be backed up using the following options in oracle? Any pointer from the documentation would be much appreciated.
RMAN
Data pump
2) How to move the flashback data archive table from one database to another? The reason why I am asking this question is that the history data for flashback data archive table is managed by undo tablespace. In this case, if I simply export the flashback data archive enabled tables to another database, will I able to view the history information?
Regards,
Richard

Hi Morgan,
Thanks for your response. Our intention is that to configure the total recall feature in the reporting instance for historical data view. Let's say , we are mining the changed data from the OLTP instance to reporting instance via logical standby. In this case, the history data will be maintained in the reporting instance?

Data automatically become null in Oracle 11g DB

We setup an Oracle 11g database for our application. Yesterday I have noted that in a table Contract_Owner the effective date for the owner FQYX1 is 30-Oct-12. But all of a sudden it has become NULL today. Im not sure how it has changed from 30-Oct-12 to NULL.
Any ideas/thoughts will be appreciated greatly ....

Oracle wouldn't change a value to a NULL unless it is told to do so.
It could have been a user , a developer, a power user / super user.
It could have been application code.
It could have been a trigger.
It could have been a mistakenly-written update.
It could have been a scheduled job or a one-off job.

Automatic table partitioning in Oracle 11g

Hi All,
I need to implement automatic table partitioning in Oracle 11g version, but partitioning interval should be on daily basis(For every day).
I was able to perform this for Monthly and Yearly but not on daily basis.
create table part
(a date)PARTITION BY RANGE (a)
INTERVAL (NUMTOYMINTERVAL(1,'*MONTH*'))
(partition p1 values less than (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
Table created
create table part
(a date)PARTITION BY RANGE (a)
INTERVAL (NUMTOYMINTERVAL(1,'*YEAR*'))
(partition p1 values less than (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
Table createdBut if i use DD or DAY instead of YEAR or MONTH it fails......Please suggest me how to perform this on daily basis.
SQL>
1 create table part
2 (a date)PARTITION BY RANGE (a)
3 INTERVAL (NUMTOYMINTERVAL(1,'*DAY*'))
4 (partition p1 values less than (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
5* )
SQL> /
INTERVAL (NUMTOYMINTERVAL(1,'DAY'))
ERROR at line 3:
ORA-14752: Interval expression is not a constant of the correct type
SQL> create table part
(a date)PARTITION BY RANGE (a)
INTERVAL (NUMTOYMINTERVAL(1,'*DD*'))
(partition p1 values less than (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
); 2 3 4 5
INTERVAL (NUMTOYMINTERVAL(1,'DD'))
ERROR at line 3:
ORA-14752: Interval expression is not a constant of the correct typePlease suggest me to resolve this ORA-14752 error for using DAY or DD or HH24

Yes, for differenct partitions for different months.
interval (numtoyminterval(1,'MONTH'))
store in (TS1,TS2,TS3)
This code will store data in partitions in tablespaces TS1, TS2, and TS3 in a round robin manner.
for Day wise day yes you can store
INTERVAL (NUMTODSINTERVAL(1,'day')) or
INTERVAL (NUMTODSINTERVAL(2,'day')) or
INTERVAL (NUMTODSINTERVAL(3,'day')) or
INTERVAL (NUMTODSINTERVAL(4,'day')) or
INTERVAL (NUMTODSINTERVAL(5,'day')) or
INTERVAL (NUMTODSINTERVAL(n,'day'))
