Oracle Database Maximum size (Linux)

What is the maximum size possible
for an Oracle Database on Linux ?
Is it limited to 2GB ? (the max file size
under Linux)
Mysql allows 4GB max, but for each table.
In fact 2GB with Linux (due to Linux
Max file size = 2GB).
null

Log to sqlplus as system ...
1. Create a new tablespace & datafile.
CREATE TABLESPACE "TESTSPACE" DATAFILE '/db/u01/oradata/testdata.dbf' SIZE 1000M DEFAULT STORAGE ( INITIAL 100K NEXT 2K MINEXTENTS 2 MAXEXTENTS UNLIMITED PCTINCREASE 0 ) MINIMUM EXTENT 2K
2. Then add datafiles to the tablespace as needed...
ALTER TABLESPACE "TESTSPACE" ADD DATAFILE '/db/u01/oradata/testdata2.dbf' SIZE 1000M
This will add two 1000m datafiles...
You can alter and make the files sizes larger and smaller... You can also add more files...
Also when you create tables make sure you reference them to the testspace tablespace or they will default to the user tablespace which will not be able to accomodate large data without modification.
This is really just the tip of the iceberg...
I really recommend reading the server concepts manual.

"Personal Edition" & "Oracle Database 10g for Linux"

Is there a personal edition for "Oracle Database 10g for Linux" ?

The enterprise edition download CD will give you the option of installing the personal edition as one of the install options.

Installing Oracle Database 10g on Linux Red Hat 5.1

While inslalling Oracle Database 10g Client Release 2 (10.2.0.1.0) for Linux x86-64 on Red Hat Enterprise Linux Server release 5.1 (Tikanga) we've got an error
Checking operating system version: must be redhat-3, SuSE-9, redhat-4, UnitedLinux-1.0, asianux-1 or asianux-2
Failed <<<<
Could we install Oracle Database 10g on Linux Red Hat 5.1 or we need only Oracle Database 11g?

Verify that the redhat-release RPM is installed on your Red Hat system:
rpm -q redhat-release
This RPM is important for RHEL since RHEL AS 4, RHEL AS 3, and RHEL AS 2.1 are Linux releases supported by Oracle. Without this RPM, Oracle 10g OUI won't be able to recognize it as a supported OS. However, the installer of 10g 10.1.0.3 does not recognize RHEL AS 4 as a supported release yet. This means that you will have to edit the /etc/redhat-release file. You also have to change /etc/redhat-release for unsupported releases like Fedora Core and RH9.
I do not recommend to execute "runInstaller -ignoreSysPrereqs" since this will disable other checks you probably don't want to.
On RHEL AS 4 (for 10g R1), RH9, and FC 1 you have to change the /etc/redhat-release file to make Oracle 10g believe it's running on a supported release.
Regarding RHEL AS 4, the installer for 10g 10.1.0.3 does not recognize RHEL AS 4 as a supported release but 10g R2 OUI does.
To change the /etc/redhat-release file, you can simply copy/paste the following commands:
su - root
cp /etc/redhat-release /etc/redhat-release.orig
cat > /etc/redhat-release << EOF
Red Hat Enterprise Linux AS release 3 (Taroon)
EOF
After you are done with the Oracle10g installation, undo the changes you made to /etc/redhat-release:
su - root
cp /etc/redhat-release.orig /etc/redhat-release

Does Veridata have Agent for oracle database 11gr2 on linux?

Hi,
Does veridata have agent for oracle database 11gr2 on linux? From the edelivery.oracle.com, I just found the latest version is 10.2. When I installed the 10.2 version agent for oracle database 11gr2, the agent needs libnnz10.*. Does 10.2 version agent support for 11gr2 database? Thank you.

Installing Oracle Database 11gR2 on Linux with Unbreakable Ente. Kernel

Hello,
I have Oracle Linux 5.5 with Oracle's Unbreakable Enterprise Kernel.
what do I need to have/prepare to install Oracle database 11gR2 on it?
the hardware part and the partitions are done!
1-
Do I need to install/run Oracle Validated Configuration RPM? even if I have Oracle's Unbreakable Enterprise Kernel?
if yes does in means the Oracle's Unbreakable Enterprise Kernel does not prepare/configure the system to host database?
2-
With any of the above
do I still need create or edit the /etc/sysctl.conf file, and add or edit lines similar to the following:
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
I saw allot of docs out there, but none answered these questions!
so please do not post docs or links to a general sites!
Thank you for the help

Dude wrote:
The intention of Oracle UEK is quite obviously Oracle specific, so I think it is legitimate to ask why not to include the Oracle specific kernel configuration file. The UEK is a drop-in replacement for the existing kernel. Why would we include the oracle-validated configuration options into the kernel package when we already have a perfectly good oracle-validated RPM that can be used with both kernels? Also, the UEK may be Oracle specific, but it's not database specific. Keep in mind that Oracle has thousands and thousands of products. :) I run the UEK on lots and lots of servers, many of which don't run database and many of which have completely different /etc/sysctl.conf configurations.
The list of available packages and add-on's at http://public-yum.oracle.com/repo/OracleLinux/OL5/5/base/x86_64/ is growing. So perhaps it's just a matter of continued development.
Not sure what the point of this statement is: there are no plans to incorporate the oracle-validated configuration into the kernel, as it already exists in oracle-validated.

Oracle database Structure Size

HI ,
Can any one tell me how to find the size of a oracle database with out data , meaning only the structure meta data only.
Thanks
lbn76

Hi
plese explain Youre question
Do You want to get DDL-statement to recreate objects ?
The space which You allocated for database is reserved and marked on blocks.
Free bloks doesn't belong to a reserve of an empty space of operating system .
I think if You whant to get size of the absolutely empty database
You need to calculate sizes of minimum necessary files in tablespaces SYSTEM, SYSAUX, Redo-files, control files , password- and controlfiles
or shrinking every table to a minimum space, move HWM and then calculate the size that Youre database occupy

Problem with Oracle database Express Edition (Linux)

I installed oracle-xe on my machine (ArchLinux x64), and all worked fine before a reboot. After it, I still can connnect to the db with sqlplus, but can't connect to apex (http://localhost:8080/apex/f?p=4950) and can't get a connection using ojdbc:
Exception in thread "main" java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection.
I tried to reinstall the db several times, but the result was always the same: all is ok only before rebooting. I'm a newer with Oracle database and can't find a solution. Could you give me some tip about it?

The problem was solved by changing permissions for log directory :
sudo chmod -R 777 /usr/lib/oracle/product/11.2.0/xe/log

Aperture database maximum size

is there any recommendet maximum size for Libs ?
I´m using an iMac 4GB RAM Intel dual core

Don't know what the absolute limit might be; there are some here with well over 100,000 images. Practical limits are:
-- Around 10,000 images in a single project. As I think of projects as rolls of film, my largest is only 200-300 images.
-- Physical disk space. A "managed" library cannot span more than one logical volume. But the largest element in your library is likely to be your master images, not your indices or previews, so by moving your master images out of the library ("referenced" masters) you can scatter them over any number of volumes. As shown by Kevin Doyle's research, only the indices/versions/previews need be on a fast drive. So, with the masters removed from your library, and the library placed on a fast, internal drive, you can manage a lot of images. Takes a little care and attention, but works very well. (Sierra Dragon, among others, is a strong proponent of this structure. Search some of his posts.)
The occasional defrag of the library itself speeds up scrolling, searching, and exporting. The master images themselves, as they are never rewritten, do not fragment. (Unless, of course, they were fragmented when first written.)
What is your problem or worry?

ISE Internal Endpoint Database maximum size

Hi all,
I am still doing my research, but I was wondering if anyone knows if there is a limit or maximum number of entries into the ISE Internal Endpoints Database which we use for MAB Authentication.
thanks
Abraham

Hi,
Cisco ISE has an internal user database and internal endpoint database that stores information about all the devices and endpoints that connect to it.
It all depends on the license you purchase and size of the disk you have.
Yes, there is no as such limitation uptill now.

Oracle database maximum CPU & RAM support

Ok, I've hunted high and low on oracle.com, OTN and the newsgroups before I came here so please bear me on this very basic question.
As a consultant, I've been asked a number of times by customers:
1. What is the maximum number of CPUs an Oracle 8i/9i database STANDARD edition supports?
2. Is the number the same for Unix and NT?
3. What is the maximum amount of RAM supported by the STANDARD edition database?
4. Again, is it the same for Unix and NT?
Sorry if this is very basic stuff but strangely, after having been an Oracle user for 7 years, I never knew this info.
joe.

I don't think the previous response caught the Standard Edition part of your question.
1. What is the maximum number of CPUs an Oracle 8i/9i database STANDARD edition supports?4 processors is tha max for Standard Edition, to support more you need Enterprise Edition.
2. Is the number the same for Unix and NT?Yes
3. What is the maximum amount of RAM supported by the STANDARD edition database?
4. Again, is it the same for Unix and NT?I don't know of a max but that doesn't mean there isn't one.
Standard Edition also doesn't have the advanced replication, VLDB, parallel processing and OLAP features that Enterprise Edition has,
along with some other things.
Hope this helps.

Oracle Database XE Client(winXP) vs Oracle Database XE (linux)

hi everybody there, thanks for having some time for reading me.
i have a linux with Oracle Database XE, under linux with database user 'hr' i can make queries and create applications, that is ok.
also, i've installed Oracle Database XE Client on windows xp machine, and i'am usin this option: Run SQL Command Line, this prompts me to enter user and password, and i am entering this:
connect hr/[email protected]:1521
after a few seconds, i get this error: ORA-12560: TNS:Protocol Adapter Error.
192.168.0.102 is the IP address from my linux database, 1521 is the default port (i am using this port).
is this client looking for file tnsnames.ora? what else do i need on client (or server), to connect to my linux database?
my final aim is to connect from Developer 9i (winxp) to my linux database (in fact, i have the same error of above, trying this), only that i am trying first just to connect from Client XE to my linux, and when i get success with this, i will continue trying with Developer 9i.
if someone can guide me with this, it would be great. i am becoming crazy.
thanks.

hi, thanks friend.
look, as i also installed Developer 9i, i have a directory where i put a tnsnames.ora file, this directory is: d:/OraDev9i/network/admin
i don't know if Client XE, looks for this directory?, if i would not have installed Dev 9i, where can i put this tnsnames.ora file for Client XE to read it?
well, let's asume Client XE looks for directory above, this is my tnsnames entry, pls check it:
XE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
i don't know if there is something wrong with this, please help me.
i did what you told me:
connect hr/francis2010@XE
and i got this:
ORA-12154 TNS: Could not resolve service name
also, i tried changing 'localhost.localdomain' to my linux IP address: 192.168.0.102, and i get the same error message. how do i know where Client XE is reading my tnsnames?
about the listener, i checked with this: sudo /.../init.d/... status, and it seems it is ok, remember i can work well in linux wiht hr, the port is ok, and i also checked with lsnrctl status, and i got LISTEN, so it seems is ok.
sorry, and thank you for your support, maybe this is easy but as i know the basics, i am lost.

Oracle Database migration to Exadata

Dear Folks,
I have a requirement to migrate our existing Oracle Database to Exadata Machine. Below is the source & destination details:
Source:
Oracle Database 11.1.0.6 Verson & Oracle DB 11.2.0.3
Non-Exadata Server
Linux Enivrionment
DB Size: 12TB
Destination:
Oracle Exadata 12.1
Oracle Database 12.1
Linux Environment
System Dowtime would be available for 24-30 hours.
Kindly clarify below:
1. Do we need to upgrade the source database (either 11.1 or 11.2) to 12c before migration?
2. Any upgarde activity after migration?
3. Which migration method is best suited in our case?
4. Things to be noted before migration activity?
Thanks for your valuable inputs.
Regards
Saurabh

Saurabh,
1. Do we need to upgrade the source database (either 11.1 or 11.2) to 12c before migration?
This would help if you wanted to drop the database in place as this would allow a standby database to be used which would reduce downtime or a backup and recovery to move the database as is into the Exadata. This does not however allow you the chance to put in some things that could help you on the Exadata such as additional partitioning/adjusting partitioning, Advanced Compression and HCC Compression.
2. Any upgrade activity after migration?
If you upgrade the current environment first then not there would not be additional work. However if you do not then you will need to explore a few options you could have depending on your requirements and desires for your exadata.
3. Which migration method is best suited in our case?
I would suggest some conversations with Oracle and/or a trusted firm that has done a few Exadata implementations to explore your migration options as well as what would be best for your environment as that can depend on a lot of variables that are hard to completely cover in a forum. At a high level I typically have recommended when moving to Exadata that you setup the database to utilize the features of the exadata for best results. The Exadata migrations I have done thus far have been done using Golden Gate where we examine the partitioning of tables, partition the ones that make sense, implement advanced compression and HCC compression where it makes sense, etc. This gives us an environment that fits with the Exadata rather then a drop an existing database in place though that works very well. Doing it with Golden Gate eliminates the migration issues for the database version difference as well as other migration potential issues as it offers the most flexibility, but there is a cost for Golden Gate to be aware of as well so may not work for you and Golden Gate will keep your downtime way down as well and give you opportunity to ensure that the upgrade/implementation will be smooth by giving some real work load testing to be done..
4. Things to be noted before migration activity?
Again I would suggest some conversations with Oracle and/or a trusted firm that has done a few Exadata implementations to explore your migration options as well as what would be best for your environment as that can depend on a lot of variables that are hard to completely cover in a forum. In short here are some items that may help keep in mind exadata is a platform that has some advantages that no other platform can offer, while a drop in place does work and does make improvements, it is nothing compared to the improves that could be if you plan well and implement with the features Exadata has to offer. The use of Real Application Testing Database Replay and flashback database will allow you to implement the features, test then with a real workload and tune it well before production day and allow you to be nearly 100% confident that you have a well running tuned system on the Exadata before going live. The use of Golden Gate allows you to get an in Sync database run many replays of workloads on the Exadata without losing the sync giving you time and ability to test different workload partitioning and compression options. Very nice flexibility.
Hope this helps...

Saving files as BLOB into oracle database

I have files to insert into the oracle database as a BLOB field. Please give me some code to display and store the files into the database.
Cheers..,
aruni.

Is your suggested approach limited by Oracle's 4k limit? No it isnt limited to 4k ...Somehow that 4k chunk is stuck in the back of my mind as a limit... Anyway, I recalled some one posted a question regarding Oracle's BLOB/CLOB and was having difficulty either reading or writing so I've decided to poke around a little and this is what I came up with:
1) Oracle's maximum size of a BLOB/CLOB is said to be 4gb -- but I failed to see how that can be accomplished thru Java since the setBinaryStream and setAsciiStream methods require a signed int as a length specification.
2) In reading a LOB, the input stream has an internal MAX_CHUNK_SIZE set to 32768, in order to read anything bigger, it must be done in multiple chunks.
;o)
