Oracle .dbf filesize limitation

What is the file size limitation for the different .dbf files?
When using the trying to create our database with Oracle 8.1.7, we get the following error:
ORA-01119: error in creating database file /oradata/users01.dbf
ORA-27044: unable to write the header block of file
The partition where I am trying to install the files has a size of 30GB. I am trying to create the file with a size of 5GB and 15GB. Creating the files with a size of 1GB works fine, anything bigger that 1GB doesn't work.
Any help would be greatly appreciated.

But also, why use ODBC? It is not that much more complex to use the OCI (Oracle Call Interface) directly. The basic call interface of both are very similar. But OCI packs a much more powerful punch.
OCI is also directly supported by abstract layers in a number of languages. ADOdb for PHP and Python. DBI for Perl. Etc. Thus no need for ODBC.

Problem in Oracle EM (Database Limits - Current Open Cursors)

Hi everyone,
I have a problem in Oracle Enterprise Manager in All Metrics.
When I select in All Metrics e.g. Health Check > Maintenance it work's fine and I see a chart.
If I select in All Metrics > Database Limits > Current Open Cursors Count I got following error:
Error
oracle.sysman.dbTarget.db.emSDKOverride.page.mtrx.GetDataException: ORA-06550: Zeile 79, Spalte 16: PL/SQL: ORA-00942: Tabelle oder View nicht vorhanden ORA-06550: Zeile 51, Spalte 7: PL/SQL: SQL Statement ignored
What's the problem?
In this database instance i drop these users (schemas): dbuser, mddata, ordplugins, ordsys, si_informtn_schema!!
Can this lack of user to cause an error?
Oracle Enterprise Manager Database Control 10.2.0.0

Thanks.

Hello Mark,
personally I don;t think it is a good idea to drop schema's from the database that have been installed as part of the activation of a certain Database Option. If you don't want the option, then don't instal it.
For a complete description of the schema's you are refering to, check: http://download.oracle.com/docs/cd/E11882_01/server.112/e10575/tdpsg_user_accounts.htm#BABGIBBA

Oracle Express 10g Limitations

The FAQ specify it supports up to 4GB of User Data in addition to Oracle system data.
How do I know that I have reached the limit of 4GB of user data and what will happen to my application once I have reached this limit?

You will start to receive an Oracle error message; ORA-12952: The request exceeds the maximum allowed database size of 4 GB
You may sum bytes columns of dba_data_files and dba_temp_files views and if possible you may shrink datafiles to gain space. A similar sql script can help to identify shrinkable space you have -
SELECT file_name,
       round(f.bytes / 1024 / 1024) "Total Size M",
       round(f.bytes / 1024 / 1024) - round(s.bytes / 1024 / 1024) "Can be shrunk by M ",
       'alter database datafile ''' || file_name || ''' resize ' ||
       to_char(round(f.bytes / 1024 / 1024) - round(s.bytes / 1024 / 1024)) || ' M ;'
FROM dba_data_files f, dba_free_space s
WHERE f.file_id = s.file_id
   AND s.block_id IN
       (SELECT MAX(block_id) FROM dba_free_space WHERE file_id = s.file_id)

Recovering Data from a Oracle DBF only

Hey, I believe I know the answer but like to pose question anyway.
We had a database which the server crashed. The last backup was
in January. No archivelog at that time. The flash recovery worked
great....But the information between the backup and crash is not
there... All I saved was the DBF files in the oracledata directory...
Is there anyway to look or recover that data from some on the tables in
this file...
Now....we enabled achivelog and have a schedule task to backup and
off load daily.....
Just would like to know if there is anything we can do with the datafile...
Thank you....Any guru out there......

Yes, you can recover your data only from DBF files.
For that you need to create controlfile statement like you would get from an alter database backup controlfile to trace.
Also on one of your other instances do an alter database backup controlfile to trace and you will get lots of example ;-)
Cheers!

File adapter with QoS=EOIO Is there any filesize limitation?

Dear Experts,
I'm using a File/FTP Sender adapter with Quality of Service = EOIO (Exactly Once In Order) to keep the polled order of the files.
In the processing parameters I defined a queue name and everything is working well for small (~1 MByte) files.
But if I want to transfer bigger (~25 MByte) files, the whole Java stack collapses and the system has to be restarted.
Is there any size limitation for this own defined queues?
Have you any experience with this kind of processing?
Any comments / experiences are welcome!
Best regards,
Andras

Hello,
there are several files to poll, we have to keep the alphabetical order of them.
It seems, that we have this issue only with EOIO. (EO works good)
After the system has restarted, the first file from the queue was processed, but with a n error message "Could not delete file 'filename.dat' after processing: java.lang.NullPointerException"
(the delete option is on after the transfer)
Is there any possibility to check the mentioned "QuicSized" settings?
I just wanted to know, if there is an "unofficial" size limit of these queues.
Thank you!

Oracle Lite 8i limits

Hi,
Can I get acurate answers on the following issues:
1)What is the max db size of a OL8i database. The documentation
says 4GB, but a lot of people say that the ODB file can
not grow more than 2GB.
2)Is this a proven fact that OL8i can maintain 35 comcurrent
connections. Again, practise shows that the limit is 2-10.
3) Is it true that OLite 8i stores numeric types inefficiently:
For example a NUMBER(38) column in the big Oracle Server 8.1.5
would take much less space than NUMBER(38) column in OLite 8i.
Thank you,
Hristo

Hi Maria,
Check your Oracle Lite 8i and Developer's SQL NET
Version may be your Oracle lite 8i SQL Net version higher then
Developer's Version. So when u install Developer the SQL NET is
over written and it's not working so Ideal is first u install
Developer and then Install Oracle Lite 8i It will work.

Oracle Online backup limitations

Hi,
We are using oracle 10g for SAP.
1. In which situation oracle Online consistent backup is not useful.
2. In a situation all online relog groups are corrupted. Is it possible recovery with online consistent backup ?
3. In which recovery situation offline backup is good than online backup?
Regards,
Nani

Hi,
2. In a situation all online relog groups are corrupted.
Is it possible recovery with online consistent backup ?
Online Consistent backup only contains the offline redo log files created during a backup run. One can not get any online redo log group members from such online consistent backup. If all online redo logs are corrupted/loss then in such situation instance recovery is not possible and only incomplete partial /point-in-time recovery is possible. If the mirrored online redo log files is available then its possible to perform instance recovery.
Please refer "Recovering from Current Online Redo Log Missing" && "Recovering from One Inactive Online Redo Log Missing" topic of this useful document [Oracle Restore and Recovery|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/97a4f439-0d01-0010-d488-d29b45e2f5ab?quicklink=index&overridelayout=true].

Difference between Oracle 10g 64 bit /Oracle 10g 32 Bit Windows

Hi all
We are using 10g Oracle 32 Bit windows as well as Oracle 10g 64 Windows at some installations.
Now we tested these two systems in our office for Testing purpose on two similar machines i.e
Intel i3 with 4 GB RAM. Database size approx 4GB
We had the feeling that :-
a) Oracle datafile Filesize limitation may be there in 32 Bit system but we saw that physically around 3.5 GB datafile size
is created in 32 Bit windows also
b) Data Fetching Speed -.We thought that data fetching speed would be higher in 64 Bit machine. But we proved to
be wrong. Our sample data had approx 7 Millions records (based on Client Live data for 3 years) total in around 20 transaction tables. Further there were other additional 100-150 tables but very smaller ones just master tables
We used the same client end machine and same Front end and same queries on both servers. To our surpriise - We got the almost similar results in terms of data fetching time in both the 32 Bit as well as 64 Bit windows with similar Oracle 10g 32 bit and Oracle 64 Bit respectively
Further we find that Anti Virus Programme which may be any say Symatentic or other - troubles much more in Windows 64 Bit environment as compared to Windows 32 Bit environment from settings point of view.
Kindly advise as to
a) Whether our above observations are correct
b) Now under what situations should we use Oracle 10g 64 Windows as compared to Oracle 10g 32 Bit windows

Database size in Oracle CRM On Demand

Can anyone tell me what the database limitations on On Demand are? How many records can one store?
Many thanks in advance
JC

Hi everyone...
I am copying a reply I got from Oracle about Storage Limits. This will be helpfull to all of us.
We recently instituted a new CRM On Demand storage policy. This new policy is significantly more generous than the former policy at no additional charge. We used to offer 30MB pooled storage for Multi-tenant, 45MB for Single-Tenant Standard Edition, and 60MB for Single-Tenant Enterprise Edition (this space covered standard records and attachments).
Customers often think in terms of records and not MB, especially when they are considering importing x million contacts or other records. An average record uses 2KB. We have made the following changes:
Multi-tenant.30MB or 15,000 records. Added 100MB per user for attachments;
Single-Tenant Standard edition. 45MB or 22,500 records. Added 150MB per user for attachments;
Single-Tenant Enterprise edition. More than doubled the 60MB or 70,000 records. Added 200MB per user for attachments;
In summary the new limits are:
Storage Allotment by CRM OD Offering
Records per User
Megabytes for Attachments to Records per User
Multi-Tenant
15,000
100
Single-Tenant Standard Edition
22,500
150
Single-Tenant Enterprise Edition
70,000
200
Partner Relationship Management
5,000
25
Additional Purchase: 10USD per month
50,000
300
A couple of additional notes:
When counting records we are only counting primary data records. Meta-data and configuration records don’t count against the limit. Similarly all of the records stored in the analytics data warehouse, back-up, etc. don’t count against the limit.
Usage is pooled as before (i.e. a customer receives the amount of storage per subscriber as listed above multiplied by numbe! r of subscribers).
You can view the number of users for a Company on the Company Profile in the Licensed Users field.
We have added a number of usage reports in R18 but they are focused on users logged in, what objects they are accessing, and configuration information. They do not include storage yet. Similar to ! our current policy, we will not be actively enforcing this limit against all customers. Instead, we look for customers egregiously abusing the storage limit and notify them so they can correct their usage. These limits should also provide a good guideline when customers are deciding how much data to import (i.e. it may be better to clean the data first and import the million records you really need rather than importing all 10 million records when 90% of them are redundant or obsolete).

Conversion of SQL Server UDF to Oracle

Hi,
I hope this is the right place to post this question.
We are migrating a number of applications from SQL Server to Oracle, so my exposure/experience in Oracle is very limited.
I had previously created a functin in SQL Server which takes data in this format
Name, CC_Code
Alan, 3720
Alan, 3730
Alan, 3740
Anna, 5045
Barry, 5004
Barry, 7518
and produces this
Name, CC_Code
Alan, 3720, 3730, 3740
Anna, 5045
Barry, 5004, 7518
I was able to cobble together the select statement below, which returns the correct output, but I am unable to create it as a function.
SELECT name,
LTRIM(MAX(SYS_CONNECT_BY_PATH(cost_centre_code,', '))
KEEP (DENSE_RANK LAST ORDER BY curr),',') AS CC_Code
FROM (SELECT name,
cost_centre_code,
ROW_NUMBER() OVER (PARTITION BY name ORDER BY cost_centre_code) AS curr,
ROW_NUMBER() OVER (PARTITION BY name ORDER BY cost_centre_code) -1 AS prev
FROM (select * from mnt_staff, mnt_cost_centre_staff
where MNT_STAFF.employee_number = MNT_COST_CENTRE_STAFF.employee_number
and mnt_cost_centre_staff.association_flag = 'S'))
GROUP BY name
CONNECT BY prev = PRIOR curr AND name = PRIOR name
START WITH curr = 1;
When I create the function, using Toad for Oracle, I get no compile errors, but when I try and use it
select MNT_USER."NameSecondary"
FROM (select * from mnt_staff, mnt_cost_centre_staff
where MNT_STAFF.employee_number = MNT_COST_CENTRE_STAFF.employee_number
and mnt_cost_centre_staff.association_flag = 'S');
I get the following error
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "MNT_USER.NameSecondary", line 6
exact fetch returns more than requested number of rows
Cause: The number specified in exact fetch is less than the rows returned.
Action: Rewrite the query or change number of rows requested
I've looked at some suggestions
"to declare the select statement as a cursor, and a variable type ref cursor to
hold the results and return them to the caller (as an out parameter)" but am lost as to what/how to do this.
Any suggestions gratefully received.

What you posted as a SQL Server function is not a SQL Server function. Neither is your Oracle SQL statement a function. A function, in Oracle, takes one or more parameters (IN, OUT, or IN OUT) and returns one and only one value unless it is a pipelined table function.
To learn about Oracle functions
http://www.psoug.org/reference/functions.html
What is appears you have done is repeat a very common error which is to think that because you know a Microsoft product you can pick up an Oracle product, having not read the concepts and architecture docs, having not taken a class, and having not studied the subject, just start banging out code: It does not work that way.
Your SQL statement, NOT A FUNCTION, is this:
select MNT_USER."NameSecondary"
FROM (
select *
from mnt_staff, mnt_cost_centre_staff
where MNT_STAFF.employee_number = MNT_COST_CENTRE_STAFF.employee_number
and mnt_cost_centre_staff.association_flag = 'S');and none of us can fix it because none of us can do more than guess as to what is specifically wrong though at the same time I can easily state that it appears that a lot of it is wrong. What is the point of creating an in-line view when all you really seem to want is:
SELECT mnt_user NameSecondary
FROM mnt_staff ms, mnt_cost_centre_staff mc
WHERE ms.employee_number = mc.employee_number
AND mc.association_flag = 'S';

Hi, oracle standard edition limited memory ram?
2gbs?Nope.
The only hardware limitation on Standard is "max 4 CPU on one server". In 10g that changes to "max 4 CPU" [I think dual-core], but no longer restricting it to 1 server.
For 9i, the rules are in the appendix of the New Features document.

Oracle XE 10.2.0.1.0 – Performance with BIG full-text indexes

I would like to use Oracle XE 10.2.0.1.0 only for the full-text searching of the files residing outside the database on the FTP server.
Recently I have found out that size of the files to be indexed is 5GB.
As I have read somewhere on this forum before size of the index should be 30-40% of the indexed text files (so with formatted documents like PDF or DOC even less).
Lets say that the CONTEXT index size over these files will be 1.5-2GB.
Number of the concurrent user will be max. 5.
Does anybody have any experience with Oracle XE performance with the CONTEXT index this BIG?
(Oracle XE license limitations: 1 GB RAM and 1 CPU)
Regards.

I have used the 100% same configuration as above, but now for the Oracle Database 11g R1 11.1.0.7.0 – Production instead of Oracle 10g XE.
The result is that AUTO_FILTER for Oracle 11g is able to parse Czech language characters from the sample PDF file without any problems.
The problem with Oracle Text 10g R2 may be I guess:
1. In embedded fonts as mentioned in the Link: [documentation | http://download-west.oracle.com/docs/cd/B12037_01/text.101/b10730/afilsupt.htm] (I tried to embbed all fonts and the whole character set, but it did not helped)
2. in the character encoding of the text within the PDF documents.
I would like to add that also other third party PDF2Text converters have similar issues with the Czech characters in the PDF documents – after text extraction Czech national characters were displayed incorrectly.
If you have any other remarks, ideas or conclusions please reply :-)

Synonym use through Oracle JDBC driver

I am trying to find out if Oracle JDBC driver can use synonym to get to an oracle object. I connect to one schema, this schema has synonym for this object and grant from other schema which is the owner of this object. Unless, I have this object's name prefixed with the schema name (which is the owner of this object) JDBC driver cannot see it. We move around oracle types(objects) to different schema for house keeping and this make our java code fail. I am trying to find out a way to remove this dependency of tacking schema name front of object name. Can you please let me know that if this is Oracle JDBC diver limitation or I should be something else?

The above link is a comprehensive "How to get set up and on my way" that I made for someone else learning Oracle/jdbc. Kind of a self-help resource page. I would start from the beginning and download the newest drivers, then set up your environment,...etc.
hope this helped,
