Will Analyze create too many redo logs ??
DB : 10gR2
Hello Folks,
Is analyze process creates too many redo log files ?? Is their any other valid option other than no log ?
I guess that's also going to create too many log switches as it's part of DDLHUH?
REDO log switches result from DML.
If you are obsessed with LOG switches, then you need to use LOGMINER to observe the the relative per centage of changed data is from DBMS_STATS
when compared to normal DML activity.
I seriously doubt that DBMS_STATS has any significant impact to redo log switches.

Hi,
I have a problem on a production server: our support partner told me that we are creating too many Archive Log files. They are not sure at all of what is happening.
Please, do you know if there is any System View which we could obtain more information about Archive Logs usage?
Thanks in advance.
Best Regards,
Joan PadillaHi Joan,
The sensible number of archive logs is determined by your backup and recovery strategy. You can delete them, once you have back-upped the database and the archivelogs. Further info in the Backup and Recovery Concepts manual.
You can find information on them in v$archived_log.
If you decide to delete them without having read the aforementioned manual, I will pray for you you don't suffer a hard disk crash.
You may want to review the relationship with your support partner too.
Their advice is not exactly professional.

Create procedure is generating too many archive logs
Hi
The following procedure was run on one of our databases and it hung since there were too many archive logs being generated.
What would be the answer? The db must remain in archivelog mode.
I understand the nologging concept, but as I know this applies to creating tables, views, indexes and tablespaces. This script is creating procedure.

So, how could I assist our developer with this, so that she can run it again without it generating a ton of logs ? ?
Thanks
Oracle 9.2.0.5
AIX 5.2The amount of redo generated is a direct function of how much data is changing. If you insert 'x' number of rows, you are going to generate 'y' mbytes of redo. If your procedure is destined to insert 1000 rows, then it is destined to create a certain amount of redo. Period.
I would question the <i>performance</i> of the procedure shown ... using a cursor loop with a commit after every row is going to be a slug on performance but that doesn't change the fact 'x' inserts will always generate 'y' redo. -
System I/O and Too Many Archive Logs
Hi all,
This is frustrating me. Our production database began to produce too many archived redo logs instantly --again. This happened before; two months ago our database was producing too many archive logs; just then we began get async i/o errors, we consulted a DBA and he restarted the database server telling us that it was caused by the system(???).
But after this restart the amount of archive logs decreased drastically. I was deleting the logs by hand(350 gb DB 300 gb arch area) and after this the archive logs never exceeded 10% of the 300gb archive area. Right now the logs are increasing 1%(3 GB) per 7-8 mins which is too many.
I checked from Enterprise Manager, System I/O graph is continous and the details show processes like ARC0, ARC1, LGWR(log file sequential read, db file parallel write are the most active ones) . Also Phsycal Reads are very inconsistent and can exceed 30000 KB at times. Undo tablespace is full nearly all of the time causing ORA-01555.
The above symptoms have all began today. The database is closed at 3:00 am to take offline backup and opened at 6:00 am everyday.
Nothing has changed on the database(9.2.0.8), applications(11.5.10.2) or OS(AIX 5.3).
What is the reason of this most senseless behaviour? Please help me.
Thanks in advance.
Regards.
BurakSelam Burak,
High number of archive logs are being created because you may have massive redo creation on your database. Do you have an application that updates, deletes or inserts into any kind of table?
What is written in the alert.log file?
Do you have the undo tablespace with the guarentee retention option btw?
Have you ever checked the log file switch sequency map?
Please use below SQL to detirme the switch frequency;

Portal creates too many database sessions. fix doesn't work!!
Oracle Database 9i, Application Server 9iAS,
Operating System SUSE Linux 7.2
CPU - Athlon 1400
Ram - 1GB
There is a modification for the http server that aims to eliminate a problem on unix that causes the database to create too many sessions. The script can be found at
http://portalstudio.oracle.com/servlet/page?_pageid=1787&_dad=ops&_schema=OPSTUDIO
However the script fails to work. The http server is on port 80 with the redirect on port 7778. However going to http://myhost/pls/ results in a server error - connection refused. Is it possible that there may be an error in the script.
Thanks in anticipationok so my sound is ok now I can check that off of the list... I just looked around and found some external USB speakers that work just right. My built in computer speakers are just not the best quality.
As for the microphone, I still haven't been able to find out what is causing it to not work. I notice that it isn't actually broken since if I make a really loud noise right next to the input it will register a little but only a little bit.

here is some additional information about my sound. Also, when I open alsamixer, I find that when I go to "select sound card"(F6) I see default and HDA Intel. If the default is pulseaudio, then is it possible that pulseaudio is causing the problem? -
Hi,
I have a very light application in Oracle 9.2.0.7 in Linux-32bits that is generating 400 logfiles a day. I can´t find why those logs are being generated!
The only thing relevant in that application is a big table that serves only for insert command (1000 per hour) for audit reasons. But this table was created with NOLOGGING option.
Redo Size: 4 groups of 40 Mb each.
The insert statement uses a sequence to generate a unique key. Is this sequence causing my big logfile generation?
Thanks,
Paulo.Here is the statspack:

DROP and recreate the database. It is a *new* database without any data.
Check what datafile locations and redo log file locations you specify when creating the new database. Check if you have permissions and enough disk space.

Creat too many instance when writing an oracle database
Hi
I want to write Oracle database with database toolkits;
but..i found there are too many instance or called session（exceed the upper limit) created when the program running . that makes the Orace server stop responding
Is there anything i need to modify？
Attachments:
Oracle DB.vi 36 KBFrankly I have never seen this problem, but then I make a point of never using the database connectivity toolkit. Assuming a Windows platform, Windows implements something called connection pooling so when you "close" a connection the OS inserts it into a pool so If you ask for another connection it doesn't actually open a new one it just gives you back a reference to one of the ones you "closed" before.
What OS are you running on?
What version of Oracle?
Is the instance of Oracle local or on another computer?
How are you communicating with Oracle (odbc, oledb, etc)?

Photoshop CS6 creates too many History States withing 1 stroke
I'm on MAC OSX 10.6.8, Photoshop CS6, using a Wacom Cintiq 12".
Too often Photoshop remembers way too many History states within one pen stroke. In previous versions I don't remember this behaviour. Previously, each stroke, no matter how long, was registered as only one History state, until I raised the pen from the tablet. Now, totally sporadically without any obvious rule, Photoshop decides to remember even 100 history states within only one stroke.
Although this is sometimes useful, if you work on really long strokes, but mostly it's highly disturbing, as after using just one tool to paint only one little circle, I loose all my other, much more important History states.
Can somebody explain to me why???Noel Carboni wrote:
Done with a mouse I get exactly one "Brush Tool" state in the history and one "Use brush" state recorded in an action.
Could it be that your tablet driver is actually delivering information to Photoshop that makes it think you're lifting the stylus and putting it down many times per stroke?
-Noel
Hmmm... could be, but I don't know how to test it, as it happens occasionally... I don't experience it in other software, but I will keep an eye on that. -
IPhones w ActiveSync creating too many connections on mail server
Over the past two days, I have started getting 503 errors, indicating too many connections. When I went to look at active connections, I noticed that the vast majority were from the iPhones that connect using ActiveSync. Just in the 45 minutes since I cleared all active connections, my iPhone has created 14 active connections. When you multiply that by the eight iPhones we have at this company the number jumps to 112. It is easy to see why the 503 error is getting generated by the end of the business day. It is as though the iPhone is unable to let go of an active connection, and just starts a new one. This only seems to be happening since the iPhone 3.0 update. Is anyone else experiencing similar issues?
Yes - I'm having a very similar problem on our server. But in this case the user has a very large mailbox - and imap processes are spawned but never die unless I go in and manually kill them.

IWeb re-creates too many pages
I understand the difference between "Publish" and "Publish All", but what I don't understand is why iWeb re-creates so many pages when I "Publish". If I work on three pages and then simply "Publish", the darn thing spends five minutes re-creating those three and a half-dozen other pages I didn't touch. Not the end of the world, but kind of annoying.
Is there something I can do to eliminate this, or can someone at least help me understand why I am sitting and watching iWeb spin it's wheels for so long?
Thanks,
BryanThe strange thing is that:
Even when the new page you are working on is in another site in iWeb the publish feature goes through some long process. While no files in the other sites are changed they are 'checked one by one,' making the publish process more tedious than it has to be.
Since the nav bar is a part of the html code all pages in the site you add a page to must be modified. If you don't wish this to happen uncheck the checkboxes in the Inspector:
1. Select the page and Open the Inspector
2. Click on the page icon.
3. uncheck 'include this page in the navigation menu.' and 'display navigation menu'
iWeb makes it very easy to create your own nav menu. Just type in some text and select it. Then open the Inspector and click on the hyperlink icon. (Arrow icon) and select 'enable as hyperlink' From the pull down menu choose one of your pages in your site.

Too many archived logs when trying a backup
Hello all,
I'm having a bit of trouble running a backup script on an Oracle instance (10g1, on Solaris).
As a normal DBA practice, I guess the backup should be scheduled and run from the very beginning of using a DB. Sometimes, from various reasons, this does not happen. In this case, before running the first (full) backup of the DB, there might be tens or hundreds of archived logs waiting to be backed up, and the flash recovery area might just not be able to handle all of them (at least that's how I see it, I might be wrong, I'm still fighting my way through Oracle's Backup and Recovery issues). In that case, a backup script containing the following RMAN sequence:
run{
allocate channel ch1 type disk;
backup
incremental
level = 0
database;
release channel ch1;
fails with the error message ORA-19804 (cannot reclaim disk space from the DB_RECOVERY_FILE_DEST_SIZE limit).
After this, the archived logs that were backed up are marked as obsolete, and I can delete them from RMAN with "delete obsolete". The script I'm using for backup runs fine afterwards. Before attempting a backup, however, no logs are reported as obsolete.
The retention policy is the default "redundancy 1" and the archivelog deletion policy is none.
How could I prevent the backup script from crashing? If I'm changing the archivelog deletion policy, will I be able to restore the DB properly from my backup set? (as earlier logs will be deleted before making a backup)
Thank you for any suggestions, your help is very much appreciated,
AdrianI am having an impression that you are not using scheduled backups and let client decided when to take backup. Well this is not good, in this case you won't be able to get rid of this error bcz you never know when the next or even first backup is going to occur and without that you can't even think of deleting your logs. If you are not using tape drives then your archivelogs and backups both will sit in recovery area and you should have enough available space to hold both of them. I would say to schedule your backups and use DELETE INPUT clause of RMAN backup to delete the archivelogs after backing them up. And also delete the obsolete backups according to your recovery window. This is the proper way to manage recovery area space. You really need to tune the recovery area space by testing the amount of redo generation, backup size, retention policy etc etc and then come up with a figure of recovery area size which is suitable for your env to hold all of the required files for required time (recover window).

SDDM 3.1 PROD: Engineer to Relational creates too many new objects
After upgrading to DM 3.1 production I am seeing many dublicates of my relational tables. It seems that when I perform "Engineer to Relational", some of the tables are recreated even though they already existed in the relational model.
Currently, I have the following tables in my relational model:
PARTIES
PARTIESv1
PARTIESv2
PARTIESv3
PARTIESv4
PARTIESv5
PARTIESv1-v5 have a created date of Februrary 15 or later, so they have all be created after my upgrade to DM 3.1 production.
Is this a known bug, and will it be fixed by the upcoming patch?
Regards,
Marc de OliveiraMarc,
I have not been able to reproduce this problem.
I assume that the problem occurred on a model you had migrated from an earlier release? If so, was the migration from 3.0 or from 3.1 EA1, EA2 or EA3? And was this where the model was initially created, or had it been migrated previous to this latest migration?
I assume that the Entities had been Engineered to Relational prior to the migration?
Is it happening to all your Tables? If not, are there any obvious similarities between the Tables that have the problem?
Any other information that might help us reproduce this problem would be appreciated. Do you use any special options in your Engineer operation?

Too Many Table logs in DBTABLOG, RSTBPDEL is taking too much time
Hi Experts,
In one of our CRM system, DBTABLOG table is logging one table which is having 1 Billion entries right now. Business dont want to switch off the logging at this moment. But the table is increasing rapidly 42 Gb per month. RSTBPDEL program is running from weeks to delete them, but no control on increment.
Can you please suggest any way to delete them quickly at first, so that my house keeping job will run daily and finish soon.
Regards,
Mohan.Hello Mohan,
The DBTABLOG table does get large, the best is to switch off logging. If that's not possible, increase the frequency of your delete job, also explore one more alternative have a look at the archival object: BC_DBLOGS, you could archive old records (in accordance with your customer's data retention policies) to reduce the size of the table.
Also, have a look at the following notes, they will advise you on how to improve the performance of your delete job:
Note 531923 - Audit Trail: Indexes on table DBTABLOG
Note 579980 - Table logs: Performance during access to DBTABLOG

Airports are creating too many separate networks, how to fix?
Here's a picture of my current setup. I have 1 Airport extreme that creates a 2ghz and 5ghz network. It travels via ethernet to a airtport express 2G that creates 2ghz and 5ghz networks of the same name as the Airport etreme.
Within that whole setup I have 2 Airport express' extending the 2ghz network which I believe is creating my problem.....
With this whole setup some sections of my home get these results:
It's quite annoying especially when streaming airplay because my iphone or such device will jump back and forth between the two networks making the music stream choppy.
How would I make both the networks merge as one? Is there a way to extend a network using ethernet as the connection instead of wifi??Oh wow, I feel like a fool, how did i not catch that >.<
Also one last question, should I allow the 2nd gen express' network to be extended whil I'm already allowing the airport extreme as well?
Thanks I'm pretty sure you fixed this
