Auto Log Mode

Hi,
Where can the Settings of the Log Mode be checked in the Database Manager 7.4.30 ?
The Auto Log Mode is at present switched off.
Should the Auto Log Mode be switched over to ON ?
How can Auto Log Mode be changed?
What is to be considered during the Restore of the SAPDB, if the Auto Log Mode is activated ?
Regards Rosemary Onanuga

Hi,
The log mode settings can be switched from the menu bar under Instance -> Set Auto Log ON or it can be done from the side bar menu under Configuration -> Log Settings. Further more there are three types of Log setting that can be done. If you turn on the Log make sure that at the filesystem level there is enough space for the Log file to be written if there is not enough space the Log process will turn off the Log mode again.
I hope this helps.
Thanks

When creating a tablespace why should we enable LOGGING when a database is already on ARCHIVE LOG mode

Question :
When creating a tablespace why should we enable LOGGING when a database is already on ARCHIVE LOG mode ?
Example:
Create Tablespace
CREATE SMALLFILE TABLESPACE "TEST_DATA"
LOGGING
DATAFILE '+DG_TEST_DATA_01(DATAFILE)' SIZE 10G
AUTOEXTEND ON NEXT 500K MAXSIZE 31000M
EXTENT MANAGEMENT LOCAL
SEGMENT SPACE MANAGEMENT AUTO;
LOGGING: Generate redo logs for creation of tables, indexes and partitions, and for subsequent inserts. Recoverable
Are they not logged and not recoverable if we do not enable LOGGING? What is that ARCHIVELOG mode does?

What is that ARCHIVELOG Mode Does?
Whenever your database is in archive log mode , Oracle will backup the redo log files in the form of Archives so that we can recover the database to the consistent state in case of any failure.
Archive logging is essential for production databases where the loss of a transaction might be fatal.
Why Logging?
Logging is safest method to ensure that all the changes made at the tablespace will be captured and available for recovery in the redo logs.
It is just the level at which we defines:
Force Logging at DB level
Logging at Tablespace Level
Logging at schema Level
Before the existence of FORCE LOGGING, Oracle provided logging and nologging options. These two options have higher precedence at the schema object level than the tablespace level; therefore, it was possible to override the logging settings at the tablespace level with nologging setting at schema object level.

I want to disable auto log-out

I have a Mac Air OS 10.9.5. Normally, when I it is either idle for a time or I close the computer, it goes into sleep mode (but it does NOT quit all applications and log out) and requires a password to use it again -- that's the way I want it.
But sometimes, it when it goes idle or I shut it, it logs out or there is a count-down to logging out that I need to cancel when I come back in. Although I DO want to have to key in my password, I don't want to have to log back in because when it logs out, it quits all my applications.
How do I retain the password function while disabling the auto-log-out function?

From the menu bar, select
 ▹ System Preferences... ▹ Security & Privacy
If there's a closed padlock icon in the lower left corner of the preference pane, click it and enter your login password when prompted.
Click the Advanced button and, in the sheet that opens, uncheck the box marked
Log out after … minutes of inactivity

Switching to Archive Log Mode

If I have an application that hooks into an Oracle 8.1.7 database running in noarchive mode, would it be transparent to that application if I were to switch oracle to archive log mode? I can't think of anything that would require configuration changes for an application that connects via Net8 but just want to be somewhat sure.
Stu

I agree. However, if you have a problem with the archive like archive dest running out of space, or you forgetting to turn on auto archiving, the application will hang on a log switch. But, these are not problems caused by archivelog mode itself, but rather by improper configuration/administration.

No logging mode

Due to some reasons, I have to stop my logging mode for some insert operation to one table , I did make the table no logging , but no use, my database still producing logs in GB's !.

I have been started the inserts again, for the last half an hour DB produced around 3 GB of log, its very low compared to the previous , but still its high I feel.
Is there any chance to view how parallel insert performing. I tried to google for monitoring options, but did not get proper queries to see whether my inserts are happening parallel or not. My parell setting are as follows.

Wifi: No longer auto log-in to home wireless network

My late 2011 MBP (10.7.3) is no longer auto logging in to my home network.
I finally got round to upgrading my old (like 8 years) modem/router for a current model D-Link Wireless N ADSL2+ DSL-2740R. link (I think this just replaced the previous model of the same name.) I gave the network the same name as my 8-year-old one and the same login password.
Everything works fine and wifi is WAY faster. Wired connections are great.
But I can no longer persuade my MBP to auto log-in to my home network. Every time I wake my MBP from sleep I now have manually to pull down on the wifi menu (network) list and locate my home network again. I tried re-ordering the list to put my home network at the top of the preferred list of networks but the problem persists. It was working just fine before the change and always auto-logged-in to my home network upon awaking from sleep or booting.

It looks like manually deleting my whole preferred network list and then re-adding my home network may have done the trick.

Standby Database (Archive Log Mode)

I'm going to be setting up a standby database.
I understand that the primary database must be in archive log mode.
Is there any reason for the standby database to be in archivelog mode?

Since your primary Db is in archive log mode, so will be your standby, when it is made primary.But. you can use STANDBY REDO LOGS from 9i version, where these Standby Redo Logs then store the information received from the Primary Database.
As per metalink:-
>
Standby Redo Logs are only supported for the Physical Standby Database in Oracle 9i and as well for Logical Standby Databases in 10g. Standby Redo Logs are only used if you have the LGWR activated for archival to the Remote Standby Database.If you have Standby Redo Logs, the RFS process will write into the Standby RedoLog as mentioned above and when a log switch occurs, the Archiver Process of the Standby Database will archive this Standby Redo Log to an Archived Redo Log, while the MRP process applies the information to the Standby Database. In a Failover situation, you will also have access to the information already written in the Standby Redo Logs, so the information will not be lost.

Is the only way to import large amount of data and database objects into a primary database is to shutdown the standby, turn off archive log mode, do the import, then rebuild the standby?

I have a primary database that need to import large amount of data and database objects. 1.) Do I shutdown the standby? 2.) Turn off archive log mode? 3.) Perform the import? 4.) Rebuild the standby? or is there a better way or best practice?

Instead of rebuilding the (whole) standby, you take an incremental (from SCN) backup from the Primary and restore it on the Standby. That way, if, for example
a. Only two out of 12 tablespaces are affected by the import, the incremental backup would effectively be only the blocks changed in those two tablespaces (and some other changes in system and undo) {provided that there are no other changes in the other ten tablespaces}
b. if the size of the import is only 15% of the database, the incremental backup to restore to the standby is small

Safari Reset, cookies cleared, but I'm still auto-logged in on a forum?

I've noticed on a few forums I use that despite clearing the cookies from Safari manually or just resetting it with all options checked, even though it shows that there are no cookies set in preferences after these operations I'm still being auto-logged into some of forums. This is Safari on 10.5 Leopard.
The login data for these forums is definitely cookie based as well because I've tried visiting them with Firefox on my Windows machine, logging in with "keep me logged in" checked, and then reset Firefox. Sure enough revisiting the sites shows me as logged out.
Not only that but Safari on my iMac which is running Tiger works as expected on the same sites. Its just Safari on Leopard that is apparently ignoring my reset command?

Well I assumed I had been, I was using the "Reset Safari" menu option and one of the selections is to clear the cache and it is selected.
I have been trying this now since I posted and it looks like I've sort of worked it out now though. I tend to reset safari then instantly quit the app with Command+Q. It seems like when I was doing that I managed to do it so fast the reset command wasn't completing before the app quit, meaning some cookies/cache/whatever remained intact.
I used reset and let it sit their open on a blank page for ten seconds before I quit and when I restarted it I was no long auto-logged in to the websites. I can only assume therefore this was the problem, although, I didn't think I was that quick at quitting the app?

SAP DB changing the Log mode to the "Owerwrite mode is ON"

Hi!
I would like to know, which consequences do I have, changing the Log mode to the "Owerwrite mode is ON".
Is that comparable with Oracle's archive mode?
What should I note proccessing so (e.g. to make back up)
I don't use the system in productive mode and would like to save/spare free space on my server....
Thank you very much!
regards
Axel

Hi Marcus,
once again to clarify: I know it from oracle: Is it right that , If I activate in SAP DB "Owerwrite mode is. ON" no new logfiles will be created.
Only the existing logfiles will be overwrtiten.
It means I "save" space, because no new log files a 4,5 GB will be created, is not?
I am not familiar with SAP DB.
How should I proceed with Backup (online, offlne)?
Thank you
regards

Question about import in archive log mode

Hello.
I am a developer, I have ordered to write a script that makes the import of a schema of a database (release 9.2.0.7). That import will be done once a day. I have seen that in my development environment the import creates 54 archivers files (10M aprox. each), that means more that half a Gb a day, it seems too much to me.
I cannot see why all those archivers can be useful. Would a good way of proceeding the following?
1. Forcing an archiver just before the import (I do not know how to do that) so that a backup could be done to the state before the import.
2. Disabling archive log mode during the import and enabling it just after the import (I do not know how to do that).
3. Forcing a new archiver just after the import (I do not know how to do that).
Thanks in advance.

540M is not that much.
One would question why you need to import every day,
there must be better ways to do this.
The three steps you propose look like an awful
scenario, as it would require the database to switch
from archivelog to noarchivelog and vice versa.
This would require the database to close twice a
day.
The scenario is also incomplete as one would need to
take a backup after the import
If you can convince your DBA to close the database
twice a day, he should write the script, which he can
easily derive from the docs.
But likely he will visit Billy Verreynne to borrow
his lead pipe, and rightly so ;)
Sybrand Bakker
Senior Oracle DBAThanks for the answer.
A few things:
- Sorry for my ignorance, I have no experience in database backups, I do not understand why I need to backup just after the import.
- That database is not critical, it is just for a team who will test on that database several applications, so the database will only need to be open during the office schedule.
- I have no dba. The client has a dba for several databases but I have no contact with him/her nor my boss has.

Archive log mode in oracle 10g

Hi,
I would like to know the archive log mode in oracle 10g and I use this code in SQLPlus
select log_mode from v$database
But it displayed: "2" not : NOARCHIVELOG or ARCHIVELOG
It displayed a number, not a String.
How could I know this?
Thanks

Hi Paul
Because I am a newbie in DBA Oracle so I got many difficulties.
You are very kind to help me.
So I have some more questions:
1. when I executed this code, it always reported error:
$ tmp=`${ORACLE_HOME}/bin/sqlplus -s / as sysdba << EOF
set heading off feedback off;
exit
EOF`
tmp='ERROR:
ORA-01031: insufficient privileges
SP2-0306: Invalid option.
Usage: CONN[ECT] [logon] [AS {SYSDBA|SYSOPER}]
where <logon> ::= <username>[<password>][@<connect_identifier>] | /
SP2-0306: Invalid option.
Usage: CONN[ECT] [logon] [AS {SYSDBA|SYSOPER}]
where <logon> ::= <username>[<password>][@<connect_identifier>] | /
SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus'
so when I updated like this:
tmp=`${ORACLE_HOME}/bin/sqlplus -s sys/syspass@db02 as sysdba <<EOF
               set heading off feedback off;
               exit
               EOF`
It run correctly.
2. With Paul's guide:
Do not execute Oracle commands from root, execute them as oracle user. This works to me :
$ tmp=`${ORACLE_HOME}/bin/sqlplus -s / as sysdba << EOF
set heading off feedback off
alter database backup controlfile to '${CONTROLFILE_DIR}/<file name>';
alter database backup controlfile to trace;
exit
EOF`
Of course CONTROLFILE_DIR must be set to a directory with write permission for oracle user.
For ex: I have an Unix account: unix/unix
and a Sys Oracle account: oracle/oracle
I login with Unix acount (unix/unix) and call script file that contains above code.
tmp=`${ORACLE_HOME}/bin/sqlplus -s oracle/oracle@db02 as sysdba <<EOF
               set heading off feedback off
               alter database backup controlfile to '${CONTROLFILE_DIR}/backup_control.ctl';
               alter database backup controlfile to trace;
               exit
               EOF`
Unix report as following: Linux error: 13: Permission denied.
CONTROLFILE_DIR directory is read,write,execute for account unix/unix.
Of course CONTROLFILE_DIR must be set to a directory with write permission for oracle user. You mean I have to create a Unix user is the same to Oracle user so that Oracle user can have permission to write.
Please guilde more detail.
Thanks for your attention.
