Second opinion : Database events

I'm probably a bit late but I found Database events and that seems to me something I have to use... Together with SQLlite / applescript...
But I want a second opinion. Is this is the best way to store my data for free?
Because when I start using database events I will get big databases with many records and fields,...
Of course if you have a better suggestion I would like to know it..
I prefer free / open source solutions. My software budget is zero this year.
Many thanks.

What is your primary goal here - to store lots of data, or to AppleScript your data?
The reason I ask is that Database Events is your simplest path to using a database within AppleScript, however it has a few caveats.
First is that I don't know anyone that's using it at scale. I've used it myself for small data sets but I don't know anyone storing gigabytes (or terabytes) of data with it. It might be fine - I just don't hear of it happening.
The second is that, IIRC, Apple have changed their underlying database in the past, so you may need to consider what to do if they repeat that (and whether they'll provide seamless migration tools).
So if your primary goal is to store lots of data, then there are other, free, solutions out there including MySQL, PostgreSQL and more. Of course, the downside to these is that there is little or no AppleScript integration, so you're limited to interacting with then via shell commands. AFAIK all the other databases that support AppleScript (either directly or via ODBC) are commercial.

Recovering cold backup - running in circles - part 2 -Second opinion needed

Hello all,
Here I'm again but this time not to ask for a complete solution where I have to do nothing but a second opinion and some help in solving.
In the thread [Recovering cold backup - alter database open failing - running in circles |http://forums.oracle.com/forums/thread.jspa?messageID=9663720] , I was trying to recover a database (I still am) for one of our clients.
Since then a few things have changed, from our client we have no received the installation media for their database software: Oracle 10.0.1.0.2.
I have installed this on a Linux, an opensuse while they used a RHEL 4, placed the database files in the a similar map structure as theirs and made sure that all the ORACLE variables were correctly set, we have also received the pfile and I made the corresponding initfile from.
I start sqlplus / as sysdba
Mounting the database no problem.
Trying to open the database I receive the following error ORA-01207: file is more recent than controlfile – old controlfile, the error refers to the Datafile 2: '/home/oracle/product/10.1.0/oradata/orcl/undotbs01.dbf'.
Their is no corresponding error message in the alert log, well their is but it doesn't really give me the information I was looking for.

So that could mean that they've just taken a copy off the files without offlining the database first, anyway to confirm this.
I've come to a point where I have not an immediately clue of what to do, some help even a little push could be helpful.

Job on database event

Hi all,
I want to create a job based on a database event.
I want to delete records in a table that are older then for example 4 years old. Tha tabel has a create_date attribute.
Is this possible?
Ps.
Currently I would create a procedure that would check for records older than 4 years and delete them. I would then create a job that runs this procedure every year.
And then I read about jobs based on events. they work with the concept of oracle messaging and queues. This seemd a better idea.

Hi,
I don't think events would work well for your case. Database events are really AQ messages. The database really doesn't send messages, you need to create the infrastructure to enqueue messages or raise alerts yourself.
In my opinion, building the infrastructure to do this is less efficient and more complex than simply scheduling a job that runs once every so often.

How to generate an email on a database event?

Dear gurus...I've heard about diferent ways of generating email in response to a database event e.g
1 - Using UTL_MAIL package
or
2 - Event Driven Reporting feature of 10g Database and using SRW.Run_Report package to generate and mail a report.
Now I'm confused that how should I accomplish the following tasks:
(i) - How to generate an email after Insert/Update/Delete on a table and acknowledge the concerned users about that event?
(ii) - How to attach a text file with that email?

Dear Ivan...I've tried both UTL_SMTP and UTL_MAIL, UTL_SMTP is working well and sending mails but following code of UTL_MAIL is giving the error which I can't guess, why?
DECLARE
CRLF CHAR(2) := CHR(10) || CHR(13);
BEGIN
UTL_MAIL.SEND(sender => '[email protected]',
recipients => '[email protected]',
cc => NULL,
bcc => NULL,
subject => 'Test Email',
message => 'Test line1' || CRLF || CRLF || 'Test line2',
mime_type => 'text/plain; charset=us-ascii',
priority => 1);
END;
and the error is:
ORA-29279: SMTP permanent error: 554 Message is not RFC compliant
ORA-06512: at "SYS.UTL_SMTP", line 20
ORA-06512: at "SYS.UTL_SMTP", line 98
ORA-06512: at "SYS.UTL_SMTP", line 345
ORA-06512: at "SYS.UTL_MAIL", line 577
ORA-06512: at "SYS.UTL_MAIL", line 594
ORA-06512: at line 4
could u guess why this error is generating???
P.S...I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production on MS-Windows Server-2003.

**URGENT**Second opinion needed

Hey,
Currently have Iphone 3g, want to get the new blackberry bold. Prefer blackberries. Just would like some feedback on why to switch or not to switch,advantages vs disadvantages that I may not be thinking about. Have done research just need a general second opinion to fully make up my mind.

In general when one reads peoples opinion of the iPhone you hear this:
From those that traded up from basic phone to their first smart phone, the iPhone kicks bu*t.
For those that have had a smart phone (particularly Blackberry) they find the iPhone lacks in some of the things they had access to via owning a smart phone (big one is email options and how it works).
You hear mixed reviews from those that have had Blackberrys and used them to their full potential (some people just had them to had them so find the iPhone fine).
So you said you like Blackberry...I am assuming you had one and are missing some features of it. Thus the choice is based on your needs.
Those that want a richer corp. email experience find the Blackberry better.

Ingres to Oracle Migration (Database Events)

I am currently working on an Ingres II to Oracle 8.1.6 migration
project. The client OpenROAD 3.5/03 application makes extensive
use of Ingres database events.
Put simply we have a single master process which services
requests for orders from a number of child processes. There is a
desire to minimise the degree of code changes when migrating the
application. OpenROAD provides the
DBSessionObject.RegisterDBEvent and RaiseDBEvent methods which
make underlying calls to the Oracle DBMS_ALERT package.
The problem we have stems from the fact that Ingres database
events are broadcast to all sessions registered as having an
interest, much like the Oracle alerts. However, Ingres events
are retained in a queue whereas the Oracle alert messages, if
unread, are simply overwritten.
I feel the best solution would probably be to use the Oracle
DBMS_PIPE package and build dedicated pipes between each
master/child session. However, OpenROAD does not appear to
provide an interface to this package.
Does anyone have experience of this problem or have any
suggestions? I'm looking for information on how other sites have
successfully migrated between the two products. I did find a
migration toolkit but it seems to avoid the issue of database
events.
Many thanks,
Max

hello,
I am interested on the architecture which you set up to see how
you reach a base ORACLE from OPENROAD or ABF applications. Have
you planned to pass in OPENROAD 4.1? do you know the GATEWAY CA?
Thanks in advance,
Didier

Database events

gOraDatabase = gOraSession.DbOpenDatabase("<database_instance>", "<username>/<password>", OracleInProcServer.dbOption.ORADB_ENLIST_FOR_CALLBACK)
gOraSubscriptions = gOraDatabase.Subscriptions

Database event in caps

Hi everyone
I need to know if there's a way to manage database events (such as a row insert) in CAPS. Can I implemlent (or import) a trigger made in SQLServer2000 with SQLServer eway?
Thanks
Ivano

Hi Sohit,
It must work. you keep a break point and check. I had used the same same thing in one of my object.
the logic would be to
LOOP AT TOTAL.
Now check the record of TOTAL which you want to check by using offset like TOTAL+0(4) i.e. the first four characters of the total which is for the first field and by taking it do the validation by checking teh database or whatever if fails raise the error message.
ENDLOOP.
If you have any doubt write back i'll help you.
<b>Kindly reward points if it helps.</b>
Thanks and Regards

KT6V LSR (MS 7021) SATA controller card second opinion, please

I want to thank Fredrik Asenius for his reply to my previous post.
However, due to the fact that the purchase of a SATA controller card and two SATA2 hard disks will be handled, of necessity, at a distance of 800 kilometers (involving courier expenses), the technician of the store has requested that I ask for a second opinion from another expert in the forum. An error, therefore, could be very costly. (No offense of any kind intended to Fredrik Asenius)
My motherboard is the MSI KT6V LSR (MS 7021) Via KT600 Northbridge and Via 8237 Southbridge chipsets.
Both SATA connections are currently taken up by two SATA hard drives (no striping, nor mirroring in use). The rest of the installation consists of IDE CDRW and DVDRW drives, as well as an MSI Nvidia NX6200AX (256 RAM) AGP video card and a Soundblaster Live Value PCI audio card. The other four PCI slots are not occupied. The system also has 1.5 gigabytes of RAM and a 520-watt PSU. I am running Windows XP SP2 Professional.
My questions are the following:
(1) Since the two SATA connectors on my motherboard are occupied, if I wish to add another SATA device I will have to install a SATA controller card. Does the SATA controller card have to be SATA 1 or can I also use a SATA 2 controller card?
IMPORTANTLY, the technician questions whether the motherboard will accept a controller card adding more SATA devices. He says that you cannot add any more SATA devices to this motherboard. Is he correct?
(2) If it is possible to add more SATA devices using a controller card, since the chipset on the motherboard is Via the SATA controller software is also from Via. Does the SATA controller card also have to be one that uses the Via SATA RAID software? (In other words, are there compatibility issues? Can all this all work together?)
Once again, thanks for the help.

I have had a fair amount of experience with this kind of issue.
1. No, the add in card does not need to be SATA I, it can be SATA II. I recommend a SATA II card and SATA II drives. Putting SATA II drives on a SATA I controller can fail to work.
2. Is he wrong? Essentially, yes he is wrong. It depends on how literally you take his words. You can NOT add more SATA drives to the motherboard. You CAN add an add-in SATA card and then put the additional SATA drives on that new add-in card. The difference in wording the answer is critical.
You ask about the Via chipset on the motherboard and also on the add-in card. Actually, it is probably LESS likely that the add-in card will work if the chipsets are the same. The issue is the computer being able to differentiate between the two controllers. I had this very problem with a machine.
That computer had two add-in cards. Each was the same brand. The computer could not differentiate between the two cards and gave a hardware error. I replaced one of the cards with another brand and it works fine. The manufacturer suggested trying the cards in different PCI slots. I did not try that, I just got a new card because it was easier for me.
The add-in card does NOT need to support RAID, that is optional. If you do not want to use RAID, the card does not have to support it. If you do want to use RAID, obviously the card does need to support it. RAID is part hardware and part software so if the card supports it and you do not to set it up as RAID, that is fine.
One caution...If the add-in card has an external port that you want to use, be aware that there is something called e-SATA that might use an incompatable type of port connecter. I had a card with that connecter and I found that the cables are extremely expensive and also hard to find. Most external SATA connectors are the SATA I style that you are used to though.

Insert hour, minute and seconds in database

I need to work with a date with this format:
22/dec/2000:09:10:55
My problem is:
I don't now how to insert it in my database. If I declare a field date it doesn't works, even if i use To_date.
if I declare a field varchar2 I cant do operation like the difference between hours and minutes.
Thanks.
I work with oracle7.

Internally oracle stores a date variable in
integer form and hence the format is irrelevant. You can use any format that includes second's and minutes, as you need it.
What matters is how you retrieve it.
While retrieving it if you put the fetched value in date variable then things are fine, but if you want it in char / varchar then use
to_date('date_field','<format>')
I feel what you are trying to do is select on sql prompt and see the min and seconds.
I suggest you check your nls_date_format parameter on sql environment for your default date format.
You could set it according to your need like this
alter session set nls_date_format='dd-mon-yyyy hh24:mi:ss';

Refresh on Database Event

Hi Experts
I want to refresh my dashboard every time an insert or update statement is executed in the database.
The only way I found is that i refresh the site periodically ervery minute.
Is there a chance to refresh the dashboard with a trigger that fires when an insert or update is executed?
Or do you have any other idea?
Regards Norbert

I'm pretty certain event poling isn't going to help. Event poling also runs on a set schedule - it's no different than having a dashboard page automatically refresh on the same interval (assuming no caching is being used). Not sure there's a really good solution for this.
From a curiosity standpoint - what type of dashboard are you building? Curious to see what the need is for having dashboards update every time a transaction comes through. If you tell us the "why" you want to do this, maybe we could suggest a better alternative (Agents come to mind)
Thx,
Scott

Database event problem

Hi all,
I have a requirement, One table in my database is getting
updated from a remote application, As soon as the table is
getting updated or new row inserted , I should be able to trap
these events and pick up that data so as to store in an Sybase
databse table. One way I can trap event is "TRIGGERS" but I am
not allowed to create triggers on the database due to some
constraint. Is there a way to find in ORACLE other than trigger
to trap events or to perform some operation as soon as these
events ( INSERT , UPDATE) are triggered.

No. That's what triggers are for. Why can't you use triggers?

Problems with second standby database

Hello All,
I have oracle 10gr1. 1 primary db and 2 physical standby and 1 is in the same network with the primary and the other is on a remote network. The primary and the standby on the same network is working perfectly well. My problem is with the remote standby. Some log are not being archived. See output below
SEQUENCE# ARC APP
1755 YES NO
1761 YES NO
1772 YES NO
1774 YES NO
1782 YES NO
1789 YES NO
I get this error RFS[10]: "Possible network disconnect with primary database". I think it has something to do with the network connectivity of my second standby and the master db. What parameters should I tweak to avoid this?
Another thing is arhived logs from seq 1728 were not being applied. I tried manually recovering the archive log from 1728 but it says there is an error in the log. I tried getting the specified archive log from the master db and tried recovering it manually but still the same. How would I solve tjhis problem? Would rebuilding the second standby do the trick? Help needed badly.
Thanks in advanced.

Hi,
About seq 1728, if the archive has been lost or alterred, you'll have to rebuild the standby. At least take a backup of the first standby and restore the datafiles at the second standby.
About network connectivity, are you using DataGuard? If so, did you setup the FAL (Failed Archive Logs) server/client parameters on your standby? You can even set your fal_server as being both the primary and first standby..
You should investigate the network connectivity problem with your network administrator. Check alert log and trace files plus sqlnet logs to see when/where/why the communication with distant site fails sometimes.
HTH,

The account password was not specified. Error after setting up a second Crawl Database and Crawler on different server.

We have a three server farm. (SPWebTest, SPAppTest, SPDBTest)
We have added an additional database server (SPDBRMTest) and an additional application server (SPAPPRMTest).
Today I created a new Crawl Database on SPDBRMTest and a new Crawler on SPAPPRMTest.
I create a distribution rule to all crawling activity for 1 web application to the new crawl database on SPDBRMTest.
This web application was part of the original crawl and had no errors or issues. We are trying to scale our Search to improve performance but when a full crawl is executed against this content source I get the following crawl error:
"The account password was not specified. Specify the password."
I have tried re-entering the "Default Content Access Account" but the issue continues.

Hi Brian,
when you add the crawl rules, do the account that is provided have the permission to read the content at the web application?
