Swap hardware for 10.2 database Linux (datafiles reside on SAN server).

Hello Gurus,
I am planning to upgrade hardware for two production database servers (currently Oracle 10.1.0.3.0 on Linux AS3 32bit) to New Dell Poweredge 6850 64 bit Linux AS4 upgrqade 7, Oracle 10.2.0.4.0 with replication enabled on certain tables.
The database tablespaces and datafiles exist on a SAN storage server. I was wondering what is the fastest way to hook up the new servers and migrate or integrate the currrent two databases into the new hardware. I was looking at the old "export/import" but that would have some serious downtime. Transportable Tablespaces looks like an option- but I have no experience in it.
My new servers have Oracle 10.2.0.4.0 installed and the servers are named the same as the old servers. Is there a way to have the new servers point to the SAN storage and just "pick up" the existing tablespaces and datafiles for the existing two databases? I have retained the block_size on the new configuration of 8K.
What is the fastest way to get the new hardware up and running connecting to a SAN storage device "seeing" the old database.
I would love any advice, I have a metalink account- but I thought this type of question would be better suited for the masses of experts out there who may have gine through this exercise before.
Cheers,
blakey

Seems You want to migrate from 32bit architecture to 64bit?
Then for upgrade to 10gR2 see metalink note 316889.1
And as oracle will change from 32bit to 64bit as well (not only linux will 64 bit, but oracle software as well), then additional step for changing wordsize to 64bit is needed. And that is described in metalink note 62290.1
Migration: as Your db is on san storage (everything including controlfiles, parameter files and so on) - then create equal mountpoints on new server (stop databases on old server, mount db related disks from storage to the new server) and that's it - next part is upgrade and migration to 64bit wordsize.
Probably oracle software is installed on local disks and that means You will have to manualy copy $ORACLE_HOME/dbs - spfile, password file to the new server. And of course listener.ora, tnsnames.ora files as well.
You can reffer to this metalink note 363609.1 for more details
Of course, before go through all configuration (/etc/sysctl.conf and so, create equal /etc/oratab and adjust oracle user profile for new server).
And before starting anything - take a full backup of oracle database (hot or cold, whatever You preffer).

Right hardware for oracle database

Hi All,
On what basis should i select the hardware for the oracle database?
What are the parameters to be analyzed?

It depends :
1.How many concurrent user transactions at a time ?
2.Which type of queries ?
3.Oracle Version
4.OS Version
5.Other installed and running software(s) on the computer/laptop ?
6.Which type of database i.e. DSS, OLTP, Warehouse ?
7.How many databases ?
8.Can you use EXADATA ?
9.How many and which type of Oracle database feature do you want to you use i.e. RAC, Data Guard etc. ?
10.Network, Security related software and their interaction with database.
11.etc.

Datafiles in swapping mode - for performance

Hi there,
One of the Senior DBAs told me that it is better to keep the datafiles in swapping mode, which means..
Suppose we need to create 4 Tablespaces, 2 for data files and 2 for index files and we have two drives called E, F. In this case he said, the performance will be increased if we prepare
E drive
Datafile_Tablespace_A (datafile TS no. 1)
Index_Tablespace_D (index TS for datafile no.2)
F drive
Index_Tablespace_B (index TS for datafile no.1)
Datafile_Tablespace_C (datafile TS no. 2)
According to him, Oracle works better in swapping mode, is it true? I was under the impression that index and datafile tablespaces should be built on separate drives.
Even though my quetions is in general, for reference - The OS we are using is windows 2003 server and parition is Raid-5 and the Oralce 10.2.0.1 version.
If anybody can clarify, I would be obliged.
Thanks

Irrelevant as that does not change any of the storage fundamentals in Oracle. The database does not know or care what you use as storage system.. why should it? It is the kernel and disk/file system drivers job to deal with the actual storage hardware. From a database perspective, it wants the ability to read() and write() - in other words, use the standard I/O interface provided by the kernel.
I/O performance must not be factor. If it is, then you storage layer is incorrectly designed and implemented. Striping (RAID 0) for example must be dealt with at the storage layer and not at the application layer. Tablespaces and datafiles in Oracle makes extremely poor tools to implement striping of any sort. It does not make sense to attempt I/O balancing such as striping at tablespace and datafile level in Oracle.
So why then use separate tablespaces? You may need different tablespaces to implement different block sizes for performance.. but this is an exception to the rule. And you do not address actual storage performance here, but more how Oracle should manage the smallest unit of data in the tablespace.
So besides this exception, what other reasons? Could be you want to physically separate one logical data base (Oracle schema) from another. Could be that you want to implement transportable tablespaces.
All these requirements are quite explicit in that more than one tablespace is needed. If there is no such requirement, why then consider using multiple tablespaces? It only increases the complexity of space management.
Consider using different tablespaces for indexes and table data. In a year's time, you may find that the index tablespace has been oversized and the data tablespace undersized. You now have too much space on the one hand, too little on the other, and no easy way to "move" the freespace to where it is needed.
It is far easier to deal with a single tablespace - as it allows far more flexibility in how you use that for data and index objects, then attempting some kind of split.
So I will look for a sound and unambiguous technical requirement that very clearly says "multiple tablespaces needed". If not, I will not beat myself over the head trying to find reasons for implementing multiple tablespaces.>
There are also many other threads on this forum about separating data and indexes, try and search for them.

Sizing hardware for 11i on linux

Does anybody have any experience/insight sizing hardware for a new 11i install on linux? We've estimated that we'll have about 300 named users, using finance, manufacturing and hr modules. How big/many servers do we start with?

Based on the document provided by Oracle corp. for sizing stated that
70 users per CPU and 8mb memory is required for each user to access Oracle Apps 11i.
So, you can think of 8 processors of 900 MHZ and 16 Gb of memory.
Swap space could be created and single time of physical memory because the physical memory is huge.
Upgradeable option has to be take care in near future requirement.
If you running Production and Demo and Test on the same server in sense that again configuration require to increased up.
The hard ware sizing is only for Apps 11i.
Based on the other requirement to access to the legacy systems and all let me know version of the Oracle enterprise database and no of users could access that and then I can give the requirement.
You can reach me through email: [email protected] so that I could be able to fill your expectation.
Thanks and Regards

Hardware for oracle database

Hi,
is there any good documentation source where I can find information about hardware which is good to use for oracle database.
I need to select new hardware for single instance OLTP database with ~ 150 users. Db size is not big. < 50 gb. OS - Linux Red Hat.
Any advices?
M.

Ideally you should get some benchmarking regarding your requirements and then you can choose on the Hardware. The budget also matters here.
You need to identify the response time required for all number of users, concurrent users and total size of the database. Now a days people opt Intel based (not much costly compared to SUN,IBM) and Linux operating system also.
There is no clear cut guideline.

Can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

Hi ,
Hardware Requirements
Physical memory (at least 1.5 gigabyte (GB) of RAM)
An amount of swap space equal to the amount of RAM
Temporary space (at least 1 GB) available in /tmp
A processor type (CPU) that is certified with the release of the Oracle software being installed
A minimum of 1024 x 786 display resolution, so that Oracle Universal Installer (OUI) displays correctly
All servers that are used in the cluster must have the same chip architecture, for example, all 32-bit processors or all 64-bit processors
Adequate disk space in the software installation locations to store the Oracle software
You need at least 5.5 GB of available disk space for the Grid home directory, which includes both the binary files for Oracle Clusterware and Oracle Automatic Storage Management (Oracle ASM) and their associated log files, and at least 4 GB of available disk space for the Oracle Database home directory, or Oracle home directory.
About Shared Storage
These Oracle Clusterware components require the following disk space on a shared file system:
Three Oracle Clusterware Registry (OCR) files, 300 MB each, or 900 MB total disk space
Three voting disk files, 300 MB each, or 900 MB total disk space
If you are not using Oracle ASM for storing Oracle Clusterware files, then for best performance and protection, you should use multiple disks, each using a different disk controller for voting disk file placement. Ensure that each voting disk is configured so that it does not have share any hardware device or have a single point of failure.
Network Hardware Requirements
When you configure the network for Oracle RAC and Oracle Clusterware, each node in the cluster must meet the following requirements:
Each node must have at least two network interface cards (NIC), or network adapters. One adapter is for the public network interface and the other adapter is for the private network interface (the interconnect). Install additional network adapters on a node if that node meets either of the following conditions:
Does not have at least two network adapters
Has two network interface cards but is using network attached storage (NAS). You should have a separate network adapter for NAS.
Has two network cards, but you want to use redundant interconnectsIn previous releases, to make use of redundant networks for the interconnect, bonding, trunking, teaming, or similar technology was required. Oracle Grid Infrastructure for a cluster and Oracle RAC can now make use of redundant network interconnects, without the use of other network technology, to enhance optimal communication in the cluster. This functionality is available starting with Oracle Database 11g Release 2 (11.2.0.2).Redundant Interconnect Usage enables load-balancing and high availability across multiple (up to 4) private networks (also known as interconnects).
However, When you install Oracle software, Oracle Universal Installer (OUI) automatically performs hardware prerequisite checks and notifies you if they are not met.

Swap hardware to get iPhone 4?

I have a 3GS and I am not eligible to upgrade until 4/11 (I just checked with AT&T). My wife does not have a contract with AT&T and was thinking of getting an iPhone.
Would it be possible for her to buy the iPhone 4 as a new customer, then swap hardware with me so she can use the 3GS and I can use the 4? (Yes, she approved of this, she's not into the gadgets quite as much .) I know the SIM cards are different sizes, but I didn't know if it was possible for Apple or AT&T to copy the data from one card to the other for us.

If you did this, couldn't you get your data on the new IP 4 with a itunes sync? Also, I seem to remember that an ATT store can also transfer your contacts to a new phone.

TOAD hangs, for the new Database

Hi,
My database version is:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE 11.2.0.3.0 Production
TNS for Linux: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production
My TOAD version is:
Version 10.1.1.8
We created a new database A and created a user schema.
When I login to the schema in TOAD and leave the session idle (even if I dont run any query) for a while and come back to it, TOAD gets hanged.
I get no error message or anything, it just hangs and I have to do alt+ctrl+del and end task everytime.
This does not happen with another database B.
So I assume this is not a TOAD problem.
Please advice where the problem lies.
Thanks!!

Load Balancing for Oracle Apps in linux

Dear all,
I need anykind of information for load balancing (how to do it - architecture) for oracle application in linux environment.
Just for info, the database will be on linux too using RAC (3 machines). I have 4 machines to be use as application tier.
any kind of information will be appriciated.
You can also send it directly to my email account: [email protected] or [email protected]
best regards,
Yohan

I'm in the middle of doing this right now. There is a doc on metalink (233428.1) that details the process. I would highly recommend trying this in dev/test env first. Even though the instructions are very straight forward and not very complicated, I'm still having configuration issues.

What are the steps for merging of database files ?

small no of datafiles.What are the steps for merging of database filesYou didn't mention your Oracle version.
See here for creating tablespaces http://www.adp-gmbh.ch/ora/sql/create_tablespace.html.
You can specify as many (or as few) datafiles as you like.
Then create tables in your new tablespace x_old_table_name(s) - you can Google this.
Then select the data from old_table_name(s) into x_old_table_name(s).
Drop old_table_name(s)
Rename x_old_table_name(s) old_table_name(s).
There may be a better way.

Alter database create datafile as

Hi
T1-)shutdown immediate;
T2-)Take full backup
T3-)startup;
T4-)move the objects in tablespace test1 to some other tablespace
T5-)drop tablespace test1;
T6-)create tablespace test1
datafile 'C:\oraclexe\oradata\XE\test1.dbf' reuse;
T7-)alter system switch logfile;
In some other server;
startup nomount;
restore the backupset which was taken at T2.
restore controlfile at T7.
startup mount;
alter database create datafile 'C:\oraclexe\oradata\XE\test1.dbf' as 'C:\oraclexe\oradata\XE\test1.dbf';
ALTER DATABASE RECOVER automatic database until cancel using backup controlfile;
Recovery performed succefully.
What I wanna ask is;
Since First I issue:
"alter database create datafile as ...."
The contents of this datafile should be deleted with this statement.
Why oracle doesnt give error in recovery, during appliying the statement at T4 ?
I have already deleted the contents of the datafile, how come oracle move the objects?
I hope I am clear

Hi,
although it is beyound my imagination what kind of real world scenario you are trying to simulate with your test, I can tell you why no error gets returned:
You create a new tablespace t1 after you dropped the old one. That gets stored in the current controlfile. The previous backup of the datafile of the old tablespace that incidentally has the same name is now useless for the new tablespace.
You then restore that controlfile and create the datafile manually as it looked after you created the new tablespace (empty) and then recover that. RMAN does that (without complaining even about the uselessness of your doing). If you look into that tablespace, you will see that it is empty as it was after you created it - unless you have put any objects into it after the second creation of that tablespace t1.
Kind regards

Missing Templates for Standalone Oracle Database

According to this link: [Templates Overview|http://www.oracle.com/technetwork/server-storage/vm/overview/templates-101937.html]
and this link: [Database Template|http://www.oracle.com/technetwork/server-storage/vm/database-092479.html] ...
There should be a template for a standalone (non-RAC) database.
But when you go to eDelivery there is no such template.
Why does Oracle not provide a template for the standalone database ???

You can use the templates for Oracle Enterprise Linux.
According to Readme:
"The oracle-rdbms-server-11gR2-preinstall package is installed in the templates
before the Oracle Linux 6 Update 4 templates. This package installs software
packages and sets system parameters that are required for Oracle single instance
and Real Application Cluster install for Oracle Linux Release 6.
This package creates the 'oracle' user, with an initial login group of 'oinstall',
a supplementary group of 'dba', and a home directory of /home/oracle. The
Oracle-validated package disables logins by the user 'oracle', and the password is
locked for the 'oracle' user by default. To enable the 'oracle' user account, log in
as the 'root' user to the guest virtual machine after it is booted."
If you choose to use OEL 6 Update 4 you can install the package using the package manager.
