Hot Backup for oracle database?

Dear all,
I want to change Cold Backup to Hot Backup. Does anyone how to do Hot Backup and has some simple document I can follow? If the database is running in ARCHIVELOG mode, is the size grow very fast or other effect will overcome?
Please advice,
Amy

I want to change Cold Backup to Hot Backup. Does
anyone how to do Hot Backup and has some simple
document I can follow?online/hot backup don’t need to shutdown the database we can put the database in backup mode and then start taking backup even though users database activity read/write data going on. This strategy useful if ours database goes for 24x7.
For online/hot backup the database should be in archive mode.
I hope you know how to turn on archive.Before turning on check the archive on or not.
SQL> archive log list
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     1
Next log sequence to archive   2
Current log sequence           2
SQL> you may also check it by connecting to database as sys
SQL> select log_mode from v$database;
LOG_MODE
ARCHIVELOG
SQL> if yours database is not in archive mode then first enable archive,please before turning on the archive take cold backup.
SQL>shutdown immediate
SQL>startup mount
SQL>alter database archivelog
SQL>alter database open;
SQL> archive log list
Now you are able to take hot/online backup ,its upto you you use user managed backup and recovery or use RMAN oracle own shipped free tool for backup and recovery ,however my recommendation would goes for RMAN.

http://www.oracle.com/technology/deploy/availability/htdocs/rman_overview.htm
ARCHIVELOG mode, is the size grow very fast or other
effect will overcome?However, the growing size pace either fast or slow everyday can be impractical it alls depends on activity of yours database operation.You will have to observe it yourself by turning on archive log its vary database to database activity.

HOT Backups for smaller databases

Should we schedule hot backups for small databases? the database size is around 1.5 GB. We have already scheduled daily FULL DB Export.
The database is Oracle 8i.

How to take a Hot backup of Oracle database

1: put the db in archive log mode
2: set the db_sid to correct one
3: login to sqlplus
4: verify the name of the db that you are connected to
select name from v$database;
5: check if the db is in archive log made
select log_mode from v$database;
if not in archive log mode
another command to check
archive log list;
6: find where on disk oracle writes archive log when it is in archive log mode
sql> show parameter log_archive_dest_1;
if the value is found to be 0, that means no values will be recorded, so we need to change it
sql> alter system set log_archive_dest_1='LOCATION=c:\database\oradata\finance\archived_logs\'
scope=spfile;
7: shutdown immediate; < this is done just to prepare the db for hot backups >
8: startup the db in mount mode
startup mount;
( 3 startup types : nomount - just starts the instance, mount - locates the control files and open up according to the values, open - finds the datafiles from the control files and opens up the db )
9: put the db in archive log mode
alter database archivelog;
10: open the database
alter database open;
11: check the status of the db
select log_mode from v$database;
SQL> archive log list;
12: create a directory for archived log
check if its empty, if empty we need to switch
sql> alter system archive log current;
run it 5 times < need to put / and enter > , then check the archive log dir , we will find files
13: make a table in the database and insert data in it
create table employees (fname varchar(2));
check the table
desc employees;
insert values
insert into employees values ('Mica');
14: tablespace must be in hot backup mode
check the status
select * from v$backup;
if found not active, then we need to change
we cannot put the db in hot backup mode, unless it is archive log mode
change to hot backup mode
alter database begin backup;
check the status
select * from v$backup;
15: now we can only COPY DBF FILES
copy *dbf <distination location>
16: need to take the db out to hot backup mode
alter database end backup;
17: need to make another archive log switch
alter system archive log current;
18: need to copy control files now, need to do a binary bckup
alter database backup controlfile to '<location>\controlbackup';
19: insert more values to the table
insert into employess values ('NASH')
COMMIT;
make another archive log switch : alter system archive log current;
do the same process for more values
20 : backup all the archive logs to a new location
21: shutdown the db and simulate a hw error, delete all the files from the database folder
22: try to start the sqlplus and db ::: error
23: copy all the backups to the db dir
need to copy the control files, rename the binary backup of the control file and make the copies as needed
24: try to mount the db, error < must use reset logs or noreset logs >
25: need to do a recovering of the database
shutdown
restore the archive logs
startup mount;
recover database until cancel using backup controlfile;
it will ask for a log file :
yes for recovery
cancel for cancelling recovery
26: check status: open the database in readonly
alter database open read only;
check the tables to see the data
shutdown immediate
shartup mount;
recover again : recover database until cancel using backup controlfile;
if oracle is asking for a log that do nto exist , all we have to do is type cancel
27: open the database
alter database open;
need to do reset logs
alter database open resetlogs;
28: check the db that you are connected, check the tables

A very long list ... let me make it shorter.
SQL> archive log list;If I see this:
Database log mode No Archive ModeI put the database into archivelog mode and leave it there forever.
If it is in archivelog mode:
RMAN> TARGET SYS/<password>@<service_name> NOCATALOG
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;Though there are a lot of things one could do better such as incrementals with block change tracking, creating an RMAN catalog, etc.

What commands used for taking backup of oracle database using BR*Tools

Can somebody please help me urgently to know what are the commands used for taking backup of oracle database using BR TOOLS.Also specifythe commands in detail which can be used for taking backups of oracle database ,Online Redo log files in databse using BRBACK tool,Archiving of offline, redo log files using BRARCHIVE, and Restoring a Database using BRRESTORE tool Commands(Plese specify the commands with their Syntax used).Also specify the commands with their Syntax which are used for taking backup of oracle database(online,Offline redo log files) into Tapedrives using BRTOOLS commands.
Thanking You for helping (in advance).

Dear Ashish,
BRBACKUP / BRARCHIVE calls the operating system command to copy the files.
Simple approach to get the commands is as follows.
1. Set the BR_TRACE (as given in the SAP note 29321) and run the command for which you need to know the OS / SQL commands.
2. This will generate the log file with the trace information. This trace has the information of the commands used by the job you have run.
Hope this helps.

Oracle SQL template to create re-usable DDL/DML Scripts for Oracle database

Hi,
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.
Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.
Could you please help with some ideas which can get this done accurately?
I have tried several ways, but I am not able to put together something that fulfills all requirements.
Thank you,

First let me address your question. (This is the easy part.)
1. The existence of tables can be found in DBA_TABLES. Query it and and then use conditional logic and execute immediate to process the DDL.
2. The existence of table columns is found in DBA_TAB_COLUMNS. Query it and then conditionally execute your DDL. You can copy the "before picture" of the table using that same dba view, or even better, use DBMS_METADATA.
As for your DML scripts, they should be restartable, reversible, and re-run-able. They should "fail gracefully" on error, be written in such a way that they can run twice in a row without creating duplicate changes.
3. Adding appropriate constraints can prevent invalid duplicate rows. Also, you can usually add to the where clause so that the DML does only what it needs to do without even relying on the constraint (but the constraint is there as a safeguard). Look up the MERGE statement to learn how to do an UPSERT (update/insert), which will let you conditionally "deactivate" (update) or insert a record. Anything that you cannot do in SQL can be done with simple procedural code.
Now, to the heart of the matter...
You think I did not understand your requirements?
Please be respectful of people's comments. Many of us are professionals with decades of experience working with databases and Oracle technology. We volunteer our valuable time and knowledge here for free. It is extremely common for someone to post what they feel is an easy SQL or PL/SQL question without stating the real goal--the business objective. Experienced people will spot that the "wrong question" has been asked, and then cut to the chase.
We have some good questions for you. Not questions we need answers from, but questions you need to ask yourself and your team. You need to reexamine this post and deduce what those questions are. But I'll give you some hints: Why do you need to do what you are asking? And will this construct you are asking for even solve the root cause of your problems?

RMAN backup for two databases with similar DBID

We have two databases with SID 'uiivc' and 'uiivc1' running from one of the HP Unix 11.11 PA-RISC server. I did configured RMAN backup for both databases. But it is found that both databases have same DBID [connected to target database: UIIVC (DBID=3005194057) for UIIVC & connected to target database: UIIVC1 (DBID=3005194057) for UIIVC1] and backup configured via crontab seen running fine with full backup at weekend and archivelog backup at daily for both databases. Now my query is that will it create any issues at time of restoration since both databases have similar DBID? Does RMAN uses DBID to distinguish databases?
Kindly help to clarifiy

Hi Tycho,
I configured RMAN to store controlfile backups in different folders on each database.
UIIVC database:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/hot_backups/rmanbkp/uiivc/cf%F';
UIIVC1 database:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/hot_backups/rmanbkp/uiivc1/cf%F';

And I saw backups are placing in the respective folders too. So with these settings, can I safely assume there is no issues with RMAN backup and restore having similar DBID for two databases running on same server?

How to choose a right server for Oracle Database!

Hi all,
Is there any formular that allows me to find the appropriate server configuration for Oracle database 11g?
Please help!
Thank you all.
Dan.
Edited by: Dan on 01:45 06-01-2013

Simply put ... no.
Determining the correct server is a dance between hardware vendors (one point of input to be treated with general distrust), internal expertise and experience working with similar systems, and most importantly understanding the behaviour of what you are building.
Here are some sample questions to start the ball rolling.
1. What operating system expertise does your organization have?
2. What operating system expertise is readily available in the community from which you hire applicants?
3. What type of application?
4. What are up-time expectations?
5. Requirements for high availability?
6. Requirements for time to perform a full recovery?
7. Requirements for security?
8. Storage footprint (dictates internal storage versus SAN, NAS, or ZFS)
9. Anticipated growth (3-7 years)
Everyone wants to sell you CPU clock-ticks, more RAM, more IOPS, etc. But the first thing you need to understand is the capabilities you require that are generic: Required of any solution. Only when you have a clear understanding of these factors are you ready to discuss whether the solution is a pizza box or an ODA ... an Exadata or an IBM System Z.
Far too often I find people purchasing RAM they don't need with CPU speeds that exceed the ability of their network infrastructure to move the data so pay special attention when you are ready to make your purchase to engineered systems like the ODA.

"Error while accessing porting layer for ORACLE database via getSessionId()

Hi,
My ejb3.0 Entity is created from Emp table in scott/tiger schema of an Oracle 10g database. I am guessing I made some mistake creating the datasource or uploading the driver, because when I run my application, I get a long exception stack trace. The bottom-most entry in the stack trace is:

OIM 9.1.0 install connector for "Oracle Database 10g"

Hello,
Is anybody here who succeeded to install the connector for Oracle Database 10g into OIM 9.1.0?
If yes please give me a hint
Have a nice day!

Thanks guys for the quick responses.
But I have tried both the options for putting the jar in Third Party and also by uploading using the OOTB utility UploadJar.sh.
But it is giving the same error.
I have tired rebouncing the server and also Purge cached, but no success.
Just to mention again, I have tried with all the last 3 postgres JDBC4 driver available on the site (u mentioned).
So, any other clue?
Thanks in advance.

Current Patch Set for Oracle Database Release 11.2

Hi
I am upgrading oracle 10G to 11GR2 in AIX 5.3 Environment with SAP ECC6 , I have just just installled Oracle 11.2.0.1.0 according to the "Database Upgrade Guide -Upgrade to Oracle Database 11g Release 2 (11.2): UNIX". After database software installation , in upgrade manual in section 3.4.4 it says, you need to install current patch set for oracle database 11g R2 and referencing a SAP note 1431799.
I have just read note 1431799 which says Current Patch Set for Oracle Database Release 11.2 is not generally available for SAP customers until December 2010, also I donu2019t find the note 1522330 as mentioned in 1431799.
Please let me know how I can get current patch set to apply with Oracle 11.2.0.1.0 (Is it in SAP service market place?)
I also want to upgrade my installation to oracle 11.2.0.2, please let me know where I get the patch set to upgrade from 11.2.0.1.0 to 11.2.0.2,
or
I have to live with 11.2.0.1.0 and apply SAP Bundle Patch ( SBP)

Abu Al MAmun,
I understand from your posts that you recently upgraded to 11.2.0.2.
I am having the same difficulty, of finding the current patch set for 11.2. Could you please let me know how you worked around it?
Thanks,
Siri
Hello Everyone,
I did read the post on to how you have to install the current patch set for 11.2.
But honestly, it pretty much flew over my head.
I am trying to upgrade our SAP AIX 64 bit test system from Oracle 10.2.0.4 to 11.2.0.2.
And so far I have downloaded all the required sw for the upgrade, except for the current patch set 11.2.
This is what I have right now:
1) Oracle 11.2 AIX 64 bit upgrade sw - 51038805_part 1 to 51038805_part 7 and 51039800.
2) Database Patches -->Oracle 11.2.0.2 -->
All they have here is
a. Database RDMBS - SAP_112020_201012_AIX.zip and b. SAP_112020_201101_AIX.zip
b. OPatch - OPatch_11201_Generic_v3.zip and mopatch-2_1_6.zip
c. Database Vault - DV - >Generic - p9656644_112020_Generic.zip
If I am not wrong, the Database RDBMS files are nothing but the SAP Bundle Patches that have to be installed after installing the currrent patch set 11.2.0.2 using MOPatch.
But I did not find the currrent patch set 11.2.0.2.
Could someone please explain the process to me in detail? This being my first time , I am finding it a bit hard to catch up with some of the stuff.
Thank You!
Siri

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)?
The following is my configuration in the conf\mapViewerConfig.xml:
<map_data_source name="mvdemo12"
jdbc_host="127.0.0.1"
jdbc_sid="orcl12c1"
jdbc_port="1522"
jdbc_user="mvdemo"
jdbc_password="7OVl2rJ+hOYxG5T3vKJQb+hW4NPgy9EN"
jdbc_mode="thin"
number_of_mappers="3"
allow_jdbc_theme_based_foi="true"
editable="true"/>

But it does not work.
After use "sqlplus mvdemo/[email protected]:1522/pdborcl", it connected to the Oracle database 12c.
Does anyone know it?
Thanks,

For 11.1.1.7.1 use the syntax for jdbc_sid, i.e.
//mypdb1.foo.com as described in the README,
- MapViewer native (non-container) data sources can now use database service name in place of SID. To supply a db service name, you will use the same jdbc_sid attribute, but specify the service name with double slashes in front, such as follows:
<map_data_source name="myds"
    jdbc_host="foo.com"
    jdbc_sid="//mypdb1.foo.com"
    jdbc_port="1522"
/>
For 11.1.1.7.0 use a container_ds instead.
i.e. instead of using
<map_data_source name="my_12c_test"
                   jdbc_host="mydbinstance"
                   jdbc_sid="pdborcl12c"
                   jdbc_port="1522"
                   jdbc_user="mytestuser"
                   jdbc_password="m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q="
                   jdbc_mode="thin"
                   number_of_mappers="6"
                   allow_jdbc_theme_based_foi="false"
                   editable="false"
   />
use
<map_data_source name="my_12c_test"
                   container_ds="jdbc/db12c"
                   number_of_mappers="6"
                   allow_jdbc_theme_based_foi="false"
                   editable="false"
   />
In my case the Glassfish 3.1.2.2 JDBC connection pool definition was
Property
url jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name
Uncheck the Wrap JDBC Objects option in Advanced panel, i.e. the Edit JDBC Connection Pool Advanced properties page.
Add a JDBC resource for that newly created pool
Use that in mapviewerconfig.xml as above

Server Sizing For Oracle Database

Hi All,
I need a server sizing for the below mentioned architecture:
This application is basically for logistics company which we are planing to host it centrally with two server's one server for application and one for oracle database along with DR site (Other Location). There are four locations and each location will have 20 users who are going to access this application (20 x 4= 80 Users). We are using MPLS network of 35 mbps bandwidth.
1. Application server: Windows server 2008 R2
2. Database Server: Windows server 2008 R2, Oracle 11g r2
I need a server sizing documents.
Thanks........

This application is basically for logistics company which we are planing to host it centrally with two server's one server for application and one for oracle database along with DR site (Other Location). There are four locations and each location will have 20 users who are going to access this application (20 x 4= 80 Users). We are using MPLS network of 35 mbps bandwidth.
1. Application server: Windows server 2008 R2
2. Database Server: Windows server 2008 R2, Oracle 11g r2
I need a server sizing documents.
Thanks........I'd seriously reconsider hosting Oracle db on Windows. Obviously there are many, many shops that do. And obviously it is often a case of the fact that they do not have (and choose to not acquire) expertise in Linux. But I've been in IT for 30+ years and have worked on IBM S-370 and its variants and descendents, Windows since v3, DEC VMS, IBM OS/2, Solaris, AIX, HPUX, and Oracle Linux. The first Oracle database I ever created was on Windows 3.11 and at that point I had never seen *nix. Now I am in a position to state that Windows is the worst excuse of an operating system of any I have ever used. I am constantly amazed/amused by how often (at least once a month on schedule, plus unplanned times) that our Windows SA has to send out a notice that he is re-booting his servers. I can't remember the last time we had to reboot a Linux server ( I have 4 of them)
Yes, I'm biased away from Windows, but that bias comes from experience. Hardly a day goes by that I don't see something that causes me to say to whoever is in earshot "have I told you how much I hate Windows?"I was going to refrain from commenting on that, as I assumed they're a Windows shop and aren't open to any other OS (but my assumption could be incorrect).
I haven't been working in IT for as long as many of the folks around here, only about 10 years. I'm a former system admin that maintained both Linux and Windows servers, but my focus was on Windows. In the right hands, Windows can be rock solid. If a system admin has to reboot Windows servers often, he is most likely doing something wrong, or is rebooting for security updates. It's never as simple as "Windows Sucks," or "Linux Sucks;" it all depends on who's running the system (again, in my opinion).
I have seen some windows servers run uninterrupted for so long no one could remember the admin password. But more often memory leaks and the "weekly update" (replacing last weeks bugs with this weeks) is the culprit.
Yes, it really is sad how often you have to reboot for updates if you want to keep your system current. Mind you, it's better to have the fixes then to not have them (maybe). I rebooted my servers about once every month at my old place... which is not that bad.
With that said, in my experience, Oracle on Windows is a major pain. It takes me much longer to do anything. Once you get proficient with a CLI like the bash shell, the Windows GUI can't compare.Agreed. One of my many complaints about Windows is the poor excuse of a shell processor. I'm pretty proficient in command line scripting, but still cringe when I have to do it. Practically every line of code I write for a command script is accompanied by the remark "this is so lame compared to what I could do with a shell script". Same for vi vs. notepad. But my real problem is the memory leaks and the registry. I'm fairly comfortable hacking certain areas of the registry, but the need to and the arcane linkages between different areas of the registry and how they influence 'process environment' remains a mystery to all but a tiny minority of admins. Compare to *nix where everything is well documented and "knowable".
One (of many) anecdotal experiences, this with my personal Win7 laptop. One time it crashed and refused to reboot. A bit of a google search turned up some arcane keystroke sequence to put it into some sort of recovery mode on bootup .. similar to getting into the bios, but the keystroke sequence was much more complex .. it may have involved standing on one foot while entering the sequence. Anyway, it entered a recovery process I've never seen before or since and repaired everything. My first thought was "hey, that was pretty cool." Then my second thought was 'but only Windows would need such a facility.
Bottom line? To paraphrase a famous Tom Hanks character, "My momma always said Windows was like a box of chocolates. You never know just what you'll get."Haha... I like that one. Yes, the registry is definitely horrible. It's amazing to me that a single point of failure was Microsoft's answer to INI files.
I think Windows and nix have their places. Server work definitely seems more productive to me in a nix environment, but I think I'd jump off a cliff if I had to use it as my desktop environment day-in-day-out. The other problem is application lock-down; I can't blame the OS for that, but it's a reality... and using virtualization to run those applications seems to defeat the point to me.

Installing Oracle Application Server 10.2 for Oracle Database Lite

Can anybody please tell me how to install oracle application server 10.2 for oracle database lite (i use oracle database lite for my final project). I use wi-fi connection to synchronize between pda and my laptop as server. Should i install oracle internet directory before installing oracle application server? I have difficulties in installing application server, what are the options should i take in every page of installation? Thanks before.

Install with the base, do not select any other options. Only choose webcache if you require the use of a software load balancer.

How to backup an oracle database?

I am running a oracle server on a windows box.
using the oracle 92 management console and developer tools.
Can someone instruct me on how to create a "job" that will backup my oracle databases on a daily basis?
I am more used to MS-SQL and have no clue how to do it in Oracle.
Thanks

Hi,
this is my weekly script to backup oracle database.
i run it from cron so you can schedule it in win but you must do same change there
#!/bin/bash
. /etc/profile.d/oracle.sh
TMPDIR=/opt/app/oracle/tmp
$ORACLE_HOME/bin/rman target / nocatalog log=$TMPDIR/backup_full_`date +'%Y%m%d_%H%M'`.log >/dev/null 2>&1 <<EOF
set echo on;
show all;
crosscheck archivelog all;
crosscheck backup ;
delete noprompt expired backup device type disk;
backup device type disk database tag='FULL_BACKUP';
backup device type disk archivelog all not backed up;
delete noprompt obsolete device type disk;
exit;
EOF
exit

Solaris 10 patches for Oracle Database 11gR2

Hi,
I downloaded Oracle Solaris 10 s/w from e-Delivery and got it installed. For Oracle Database 11gR2 I also need the followging patches:
120754-06: SunOS 5.10_x86 libmtsk
119961-05: SunOS 5.10_x86: Assembler
119964-14: SunOS 5.10_x86 Shared library patch for C++_x86
Though we have access to MyOracleSupport we can only download s/w patches using our support contract with Oracle and not OS patches.
Is there any other way I can get these patches.
Rgds,
Thiru.

Thiru,
You won't find the patches in the patches/ directory on the DVD or the ISO image. Oracle integrates the patches directly into the packages, so there is no need to provide or install them separately.
All patches have a patch number (e.g. 120754) and a revision (e.g. 06). A newer revision of a patch always contains all fixes of the previous revisions. So try to run "showrev -p | grep 120754" instead, and you'll see that patch 120754-08 is pre-installed. As revision 08 is newer/higher than 06, the patch requirement is satisfied.
Hope that helps,
mp.
