Database Limits

Windows Server 2008 - Oracle 11g 11.2.0
I was checking Oracle Enterprise Manager.
There is a warning as database limits saying that open cursors are at 2185.
I checked some parameters :
open_cursors : 12000
session_cached_cursors : 50
To me, it seems that the limit is far from overflowing...
So I'm trying to understand why I had this warning.
Could you please help me ?
Ed

You should be able to click on the warning link and get to an open cursors screen which will show you the warning and critical levels, as well as your recent history. On my machine it appears the default is 1200, which is far below my normal usage - it's kind of humorous that the warning message was sent at the time my usage was at its minimum. Why it checks the way it does is one of those mysteries of the universe. You might try setting the levels in the Manage Metrics screen, though on earlier versions on my platform that's been a challenge.

They assume changing the file ending actually changes the format?

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
Database instance: myDB > All Metrics > Database Limits > Current Open Cursors Count
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

Database limits of oracle lite

Could anyone please tell me the database limits(eg table
size,number of columns etc) of oracle8i lite
Thanks,
Debu

So - you are using Oracle Application Express to interact with the data stored in your Oracle Database - Express Edition.
The only limits in the database Express Edition are:
- it will not use more than 1 CPU
- it will not use more than 1 GB RAM
- it will not permit more than 4GB user data to be stored
Any other limits or limitations are from the application (or application design) or from Application Express. You might want to move this discussion to either the Application Express forum or the Express Edition forum. (Both available from http://forums.oracle.com but you need to register for the Express Edition forum, as shown on the XE home page.)

Determining database limits

I am running a bunch of code through a batch process that we've created. I'm running into the oracle error ORA-01400 which is related to not null constraints. However, I've pretty much determined that this message does not directly relate to the problem I'm encountering since it does not happen consistently and for other various reasons. So, what I was thinking was that the problem we're having is the result of some sort of database limit that we're hitting. Unfortunately, I really don't know what kinds of limits to be looking for that might be causing this problem. A couple of suggestions might be that we're running out of memory, or we've hit the max number of open cursors and the batch processing isn't able to continue. Does anyone have any idea what limits I might be interested in and where I can find what the values are set to? I appreciate any help....
Thanks!
Vanessa

The odds are that what you are seeing is what you are getting. Somewhere in your code, you a producing a null value then trying to insert it into a not null field. Usually, especially in intermittent cases like yours, this will be caused by a math equation using a null value which will always return a null i.e 5+null=null, not 5.
Amend your code by placing an exception for this error, then run your code again. When you trap the error, you can dbms_output the appropriate variable and determine which one is giving you the problem.

Database limits for Grid control repository?

Document "Oracle® Database Licensing Information / 10g Release 2 (10.2)" [Part Number B14199-10] discusses the restricted use license of database for grid control repository and rman repository use.
nfrastructure Repository Databases A separate Oracle Database can be installed and used as a Recovery Manager (RMAN) repository without additional license requirements, provided that all the Oracle databases managed in this repository are correctly licensed. This repository database may also be used for the Oracle Enterprise Grid Control repository. It may not be used or deployed for other uses.
A separate Oracle Database can be installed and used as a Oracle Enterprise Manager Grid Control (OEM Grid Control) repository without additional license requirements, provided that all the targets (databases, applications, and so forth) managed in this repository are correctly licensed. This database may also be used for the RMAN repository. It may not be used or deployed for other uses.
There is no discussion of licensing requirements for options of the database (RAC, partitioning, etc) when the database stays within these repository use restrictions. Therefore it is unclear whether the Grid Control can be configured to provide appropriate monitoring without additional licenses.

This is the reply I received from release
management:
If they have deployed an EE edition of the database
as an OEM repository, and then want to protect that
with RAC or Data Guard, or make more Secure with ASO
or Database Vault, or indeed get any of the
additional benefits any of the options provide, then
they will need to license the option.
Let me know if that is still not clear, and I'll go
back again.Thanks.
There is a minor inconsistency in their response ... they say "if deployed on EE". However, as far as I know OEM repository required VPD, which is available only on Enterprise Edition (see http://download-east.oracle.com/docs/cd/B16240_01/doc/em.102/e10953/pre-installation_req.htm#CHDGIEAD)
However, it is quite clear that 'they' are telling us that the RAC option is not inherent in the "Special Use Licensing" as described http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#CJAHFHBJ .
The implication (not necessarily a topic for this forum) is that the OEM is not guaranteed to be able to provide basic monitoring and reporting functionality without additional license fees to make OEM more highly available than the targets being monitored.
It would be nice to have the information about which Oracle products (database and app server) have included licenses with a basic Grid Control install and which require additional licenses as part of Chapter 1 of http://download.oracle.com/docs/cd/B19306_01/license.102/b40010/toc.htm (That document goes into excruciating detail about the extra packs, but ignores the basics.)
For that matter, since OEM Grid Control can not be purchased, it would be nice to have a list of products that provide license to install Grid Control, again in Chapter 1 of the Grid Control Licensing document listed above.
I appreciate your time in having dug into this.

10g flashback database limitations

When are you not able to Flashback Database?
· Media failure, corruption or datafile deletion.
· The control file has been restored or recreated
· A tablespace has been dropped
· A data file has been shrunk
· A RESETLOGS operation is required.
If you dropped a schema and want it back, you can use flashback database to get it back. But if you dropped both schema and tablespace, it is not possible to get the schema back with flashback database.
Is there any other scenarios to use flashback database?

I am trying to evaluate the benefit to turn on this feature. Please drop few lines of your opinion to help me.

Any database limits like no. of dimensions, levels & hierarchies etc?

Couldn't find these information from documentation (11g OLAP) or if such limit exists?
Also, any max. limit on number of dimensions for a cube?

When Adobe says that SVG viewer is not supported, all that means is that Adobe is not going to release any new patches or releases for SVG viewer. The last version available on their site still works with IOP. Over time, this svg viewer will get replaced with the Oracle EPM specific addins.

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).

Discoverer 10g Limitations....

Hi,
Is there any document or can you give me some info about Discoverer 10g limitations.... such as the maximum folders per business areas , hierarchies.... e.t.c.
Regards,
Simon

Hi
I don't believe there are any physical limits to things such as folders, items, hierarchies and so on. The only limits you have is memory, CPU capacity, network bandwidth, hard disk storage and the database limits.
Of course, memory is the one you are most likely to run into trouble with so the more memory you have the better Discoverer Plus will be.
Best wishes

Maximum database size Exchange 2013 Standard

Hi,
Does anybody is aware of database size limitation for Exchange 2013 Standard. I remember in older version there was a registry tweak to increase database limits.
Thank you
alfa21

Hi,
This is the official answer :
Supported: Approximately 16 terabytes.
Best practice:
2 terabytes or less.
Provision for 120 percent of calculated maximum database size.

BLOBs and Database Links

Do Blobs work through Database Links? I have images in one database that I would like to render in a portal attached to another.

Hi I tried the following in sqlplus:
1)create a table(ATAB_CLOB) in a remote database(DB2) with a clob column
2)connect to the database(DB1) and create a database link (ADBLINK1) for the
remote database(DB2) .
3) create a synonym (ASYN_TAB) based on the remote table (ATAB_CLOB) using the
database link ADBLINK.
4) Now try to create a view based on this synonym,I see the same error:
SQL> create or replace view aview2 as select * from asyn_Tab;
create or replace view aview2 as select * from asyn_Tab
ERROR at line 1:
ORA-22992: cannot use LOB locators selected from remote tables
The message says it all.
This is a database limitation.
Hope this helps.

Create local oracle xe version of production database schema

Hi,
I'm not sure whether this is possible but I would like a team to have their own versions of the current live database schema content running on their own local machines using oracle xe. I've done a fair bit of research but cannot for the life of me work out if it's possible. I have no direct access to the live servers except a read only ip address, port, schema username and password so am unable to create directories or database links. What I would like to do is a direct import of all tables on the database schema from the remote server to a local database. The ideal solution is to use the impdp command but I'm unsure of the format of this command when the import is coming from a remote server as I am not allowed to logon to the live server for obvious reasons. If possible I would like to script it so avoid editing tnsnames.ora but if this is unavoidable then I will have to live with this.
Can I create a database link from my laptop to the remote server and then run the impdp? If so, what would be the format of the command given I have to use the ip address, port etc...
Sorry if this is a basic question but I would like my team to be completely independant from the network if at all possible.
Hope someone can help me.
Gareth

What I would like to do is a direct import of all tables on the database schema from the remote server to a local database. Of course you know the XE database limits...
That said, have a look at NETWORK_LINK parameter.
