Sql storage

Hello Guys, when ever a sql is executed it uses the temporary tablespace storage to do the sorting right?
very often we face the problem that the temp segment is unable to extend because the query needs more space to do the sorting.
My question is, is there any method to get an estimate on how much storage a query needs to execute. can the information of explain plan in the filed of "BYTES" or size of the table being used in the query be of any help to determine how much storage the query needs to do the sorting in the temporary tablespace?

when ever a sql is executed it uses the temporary tablespace storage to do the sorting right? Wrong. It only uses temp if it is unable to perform the sort in memory.
You can not estimate, in advance, the swap space required but you can write better queries, create sorted hash clusters, or use the right indexing, to minimize the number of sorts and the size of what is being sorted.
Without a version number, DML, and Explain Plans it is impossible to give anything other than very general advice ... but suffice it to say your basic assumption is incorrect.

PGS & ORA-06500:PL-SQL : storage error

How do I tune PGA when I get an ORA-06500:PL-SQL : storage error. Works in 8i but not 9i. 9i is auto, 8i is not. Is this it?
Tx.

Different servers? Unix? If so, check OS (ulimit -a) first and then post the results. If separate machines then it might not be PGA at all.
I would strongly suggest checking that and then posting a new, more detailed problem statement to the Database: General forum rather than posting to the Oracle Text forum (since it isn't related). Toss in info about the server type(s), memory settings that you've checked, the full error, what you're doing when you get it, etc.
Thanks,
Ron

Sql STORAGE DATATYPES

Hi There Guys!
I need a simple information about storage in oracle... what is the size of all the datatypes which there are in oracle?
The problem is this... I have to create a tablespace, so I need its storage, but I don't know what is the size of the single datatypes, and the documentation of the 11g version (that is what I need) tells a few information about it...
Thanks for all!!
See you soon!

No, no the problem is another, cause I think that is not important trought what I want to populate these datatypes, but what is the real size that characterizes theme:if I write varchar2(1), oracle allocates 1 byte, 2 byte... how much bytes it allocates? This is the problem! XD
In this way, if I have a table composed by two records: Name, Sourname, if I know what is the size of one varchar2 I can calcoulate all the size of the table.

Use external SQL storage

Can you use an external SQL server to hold TFS data? My understanding is that TFS allows up to 10 GB because it runs an internal instance of SQL Express. We need at least 15 GB. Can I configure TFS to hold the data on one of our network SQL Servers? Thanks
for any advice.
Benji Legaspi

Hi Benji,
I agree with Vladimir. You might need to use Standard Edition of SQL Server. And you can check this
page for more information about install SQL Server for TFS.

ORA-06500: PL/SQL: storage error

Hi
we faced this error while executing one of the packages.
But when we have rerun the same mapping with out any changes i did not throw this error.
What could be the possible reason. Do we need to change any of the database parameters.
Thanks
Nanda Kishore

Nanda,
Can you verify whether you have enough database tablespace available?
Thanks,
Mark.

Interface with SQL backend (foreign schema)?

I'm looking for a Radius or LDAP solution using (foreign schema) SQL storage as backend.
I do have a large user database (that must stay as-is, I only have read-only sql access) that resides on an Oracle SQL server. I know the schema and how the passwords are salted and hashed, but on the gateway I can only use Radius or LDAP as authentication protocols. This is purely for authentication, not authorization (i.e. no group memberships need to be resolved) or accounting.
Is this possible with either ISE or ACS? I know that ACS may use Oracle, but afaik only for accounting or use it as its own underlying database (which is not what I want as the users already exist in a given schema).

Hi All
Do we need to download a separate DB Adapter for Connecting to SQL Server 2005.
I have created a BPEL process using the DB Adapter provided in JDev 10.1.3.1.0
The process deploys successfully but is erroring out at point it is trying to fetch the data from SQL Server.
Error:

Welcome to the SQL Server Disaster Recovery and Availability Forum

(Edited 8/14/2009 to correct links - Paul)
Hello everyone and welcome to the SQL Server Disaster Recovery and Availability forum. The goal of this Forum is to offer a gathering place for SQL Server users to discuss:
Using backup and restore
Using DBCC, including interpreting output from CHECKDB and related commands
Diagnosing and recovering from hardware issues
Planning/executing a disaster recovery and/or high-availability strategy, including choosing technologies to use
The forum will have Microsoft experts in all these areas and so we should be able to answer any question. Hopefully everyone on the forum will contribute not only questions, but opinions and answers as well. I’m looking forward to seeing this becoming a vibrant forum.
This post has information to help you understand what questions to post here, and where to post questions about other technologies as well as some tips to help you find answers to your questions more quickly and how to ask a good question. See you in the group!

How to ask a good question
Make sure to give all the pertinent information that people will need to answer your question. Questions like “I got an IO error, any ideas?” or “What’s the best technology for me to use?” will likely go unanswered, or at best just result in a request for more information. Here are some ideas of what to include:
For the “I got an IO error, any ideas?” scenario:
The exact error message. (The SQL Errorlog and Windows Event Logs can be a rich source of information. See the section on error logs below.)
What were you doing when you got the error message?
When did this start happening?
Any troubleshooting you’ve already done. (e.g. “I’ve already checked all the firmware and it’s up-to-date” or "I've run SQLIOStress and everything looks OK" or "I ran DBCC CHECKDB and the output is <blah>")
Any unusual occurrences before the error occurred (e.g. someone tripped the power switch, a disk in a RAID5 array died)
If relevant, the output from ‘DBCC CHECKDB (yourdbname) WITH ALL_ERRORMSGS, NO_INFOMSGS’
The SQL Server version and service pack level
For the “What’s the best technology for me to use?” scenario:
What exactly are you trying to do? Enable local hardware redundancy? Geo-clustering? Instance-level failover? Minimize downtime during recovery from IO errors with a single-system?
What are the SLAs (Service Level Agreements) you must meet? (e.g. an uptime percentage requirement, a minimum data-loss in the event of a disaster requirement, a maximum downtime in the event of a disaster requirement)
What hardware restrictions do you have? (e.g. “I’m limited to a single system” or “I have several worldwide mirror sites but the size of the pipe between them is limited to X Mbps”)
What kind of workload does you application have? (or is it a mixture of applications consolidated on a single server, each with different SLAs) How much transaction log volume is generated?
What kind of regular maintenance does your workload demand that you perform (e.g. “the update pattern of my main table is such that fragmentation increases in the clustered index, slowing down the most common queries so there’s a need to perform some fragmentation removal regularly”)
Finding the Logs
You will often find more information about an error by looking in the Error and Event logs. There are two sets of logs that are interesting:
SQL Error Log: default location: C:\Program Files\Microsoft SQL Server\MSSQL.#\MSSQL\LOG (Note: The # changes depending on the ID number for the installed Instance. This is 1 for the first installation of SQL Server, but if you have mulitple instances, you will need to determine the ID number you’re working with. See the BOL for more information about Instance ID numbers.)
Windows Event Log: Go to the Event Viewer in the Administrative Tools section of the Start Menu. The System event log will show details of IO subsystem problems. The Application event log will show details of SQL Server problems.

hi,I have a question on sql database high availability. I have tried using database mirroring, where I am using sql standard edition, in this database mirroring of synchronous mode is the only option available, and it is giving problem, like sql time out errors on my applicatons since i had put in the database mirroring, as asynchronous is only available on enterprise version, is there any suggestions on this. thanks ---vijay

Error while sending notificaiton to multiple users

I created an adhoc role like:
declare
l_role_name varchar2(150):='TO_ROLE';
l_role_display_name varchar2(50):='TO_ROLE';
l_users := l_1_user||' '||l_2_user;
l_1_ruser and l_2_user are of fnd_user%user_name type..and they get the user names from fnd_user using a cursor variable.Both l_1_ruser and l_2_user are already having assigned to various roles.
But for my present scenario i am creating an adhoc role and assigning both l_1_user and l_2_user who are residing in wf_local_roles.
WF_DIRECTORY.CreateAdHocRole (
role_name => l_role_name,
role_display_name =>l_role_display_name,
email_address => null,
notification_preference => 'MAILHTML'
WF_DIRECTORY.AddUsersToAdHocRole (
role_name => 'TO_ROLE',
role_users => l_users
when using the above I am getting:

Oracle Performance tunning genral question

Hi,
Below is the list of Areas of Oracle db for which tunning activities are done. You are invited to comment to it weather this is complete list or need some addition or deletion. As I'm learning PT for Oracle now a days, therefore I want to expand my knowledge by sharing what I'm learning and what I need to learn.
So comment with Open hearts on it. Espically from experts and Gurus.
Here is the List
1-Planning for Performance, include Storage consideration( Weather it is SAN, NAS, DAS), Network planning and host OS planning with proper configuration for running Oracle.
2-Database desining (Not under-Normalized and not Over-Normalized with proper usage of Indexes, views and Stored Procedures)
3- Instance tunning (Memory structure + B.g Processes)
4- Session tunning.
5- Segment Space tunning.
6- SQL tunning.
This is what uptill what I've learned. If it needs addition kindly tell me what are these. Please also provide me links(good and precise one) for PT tutorials on web.Also note that I'm discussing this w.r.t Single instance non-rac db.
Looking for Good sugessions
Regards,
Abbasi

Best Practice for Storing Sharepoint Documents

Hi,
Is there a best practice where to store the documents of a Sharepoint? I heard some people say it is best to store sharepoint documents directly into file system. Ohters said that it is better to store sharepoint documents into a SQL Server.

What you are referring to is the difference between SharePoint's native storage of documents in SQL, and the option/ability to use SQL's filestream functionality for Remote BLOB Storage (also known as RBS). Typically you are much better off sticking with
SQL storage for BLOBs, except in a very few scenarios.
This page will help you decide if RBS is right for your scenario:

Out of process memory error

Hi
Is anybody familiar with this error, We get this error in production environment when the the dimensional mapping is getting executed. We are using OWB 9.2 and Database 9.2.0.5. I thought it was database issue, but I was curious to see something related to"OWB92.WB_RT_MAPAUDIT" ... Is it something to do with runtime parameters we pass in the mapping?
Below is the error we get in OWB Runtime audit browser , Any help or suggestion woudl be greatly appreciated.
ORA-04030: out of process memory when trying to allocate 32080 bytes (pga heap,ksm stack) ORA-06512: at "OWB92.WB_RT_MAPAUDIT", line 338 ORA-01403: no data found ORA-06512: at "OWB92.WB_RT_MAPAUDIT", line 1736 ORA-06512: at "OWB92.WB_RT_MAPAUDIT", line 2625 ORA-06512: at "ODW.ITEMS_DIM_M02", line 10407 ORA-06512: at "ODW.ITEMS_DIM_M02", line 11959 ORA-06500: PL/SQL: storage error ORA-06512: at "ODW.ITEMS_DIM_M02", line 18940 ORA-06512: at line 1
Thanks

Hi Bala,
OWB92.WB_RT_MAPAUDIT is a package that takes care of the auditing of your mappings, and therefore might cause just that bit of extra transaction on the database that causes the out-of-memory.
There is also a trick to prevent out-of-memory on your client (you can get "java.lang.OutOfMemoryError" when processing large amounts of OWB project metadata), you can alter the call to the OWB client in order to have more memory available to OWB. Check owb.cl and owbclient.bat in directory <windows OWB_HOME>\owb\bin\win32.
Standard it says "-Xmx384M -Dlimit=384M", this you can alter into "-Xmx512M -Dlimit=512M" (or maybe even more if you've got ampel internal memory).
This also applies to OMBPlus.bat.
Cheers, Patrick

Oracle Designer fail generating module

I just installed and tried the tutorial in the designer 6.0. Everything is OK (table generation is succeed).Until generating the modules, it gave me following errors:

but still no luck. What went wrong?

The best thing to do is to find a report among the reports that are supplied with Designer that contains most of the information that you want in your new report. Then make a copy of it, and use the Oracle Reports Developer to adapt it for what you need. This will give you a good example of a working report.
On the other hand, I myself am not very comfortable with Oracle Reports, so I don't do it that way. I prefer to write reports as PL/SQL Server pages and run them on the web. To make it easier, I wrote what I call a "cursor package" - a PL/SQL package containing pre-defined queries against the CI_ views in the repository. I don't currently have this available for download, but I will try to remember to add it to my web site.
Oracle has fully documented the CI_ views that make up the repository model - find the docs at: http://download-east.oracle.com/otn_hosted_doc/designer/doc_library/6i_release42/CDOC72/model/el_defs/outer_frame2_de.htm.
