Sql server data file and log file
hello experts
what is the best way to save data file and log file in a two node cluster environment. i have an active\passive cluster with windows server 2008r2 enterprise and sql server 2008r2. i am new to the environment and i noticed that all system and user databases
including their data and log files are stored in one drive, just curious, what is the best practise in such kinds of scenario, thank you as always for your help.
Make sure you have valid/tested backup strategy for both system and user databases.

System Center 2012 R2 install: SQL server Data file and log file
This might be a dumb question, but I can't find the answer anywhere.
I'm installing a new instance of System Center 2012 R2 on a new server, I'm stuck on the SQL Server data file section. Everytime I put in a path, it says that tne path does not exist. I'm I supposed to be creating some sort of SQL Server
data file and log file before this installation, I didn't get this prompt when installing System Center 2012 SP1 or hen I upgraded from System Center 2012 SP1 to System Center 2012 R2
My SQL is on a different server
Thank you in advancedHave you reviewed the setup.log?
On a side note, why would you put the database file on the same drive as the OS? That defeats the whole purpose of having a remote SQL Server. Why use a remote SQL Server in the first place.

How to design SQL server data file and log file growth
how to design SQL DB data file and log file growth- SQL server 2012
if my data file is having 10 GB sizze and log file is having 5 GB size
what should be the size in MB (not in %) of autogrowth. based on what we have to determine the ideal size of file auto growth.It's very difficult to give a definitive answer on this. Best principal is to size your database correctly in advance so that you never have to autogrow, of course in reality that isn't always practical.
The setting you use is really dictated by the expected growth in your files. Given that the size is relatively small why not set it to 1gb on the datafile(s) and 512mb on the log file? The important thing is to monitor it on an on-going basis to see if that's
the appropriate amount.
One thing you should do is enable instant file initialization by granting the service account Perform Volume Maintenance tasks in group policy. This will allow the data files to grow quickly when required, details here:
https://technet.microsoft.com/en-us/library/ms175935%28v=sql.105%29.aspx?f=255&MSPPError=-2147217396
Also, it possible to query the default trace to find autogrowth events, if you wanted you could write an alert/sql job based on this
SELECT
[DatabaseName],
[FileName],
[SPID],
[Duration],
[StartTime],
[EndTime],
CASE [EventClass]
WHEN 92 THEN 'Data'
WHEN 93 THEN 'Log' END
FROM sys.fn_trace_gettable('c:\path\to\trace.trc', DEFAULT)
WHERE
EventClass IN (92,93)
hope that helps -
SQL Server data change and Security
in our environ any user who login with sa they can change any table data.
so i write trigger to capture changed data like who change, from which IP etc this
CREATE TRIGGER [TRG_Users]
ON [dbo].[UserRights] AFTER INSERT, UPDATE, DELETE
AS
DECLARE @strIP VARCHAR(MAX)
SET @strIP=(SELECT dbo.GetCurrentIP())
IF EXISTS (SELECT * FROM INSERTED) AND EXISTS (SELECT * FROM DELETED)
--PRINT 'Update happened';
INSERT INTO Logger(IPAddress,Status)
VALUES (@strIP,'UPDATE')
ELSE
IF EXISTS (SELECT * FROM INSERTED)
--PRINT 'Insert happened';
INSERT INTO Logger(IPAddress,Status)
VALUES (@strIP,'INSERT')
ELSE
--PRINT 'Delete happened';
INSERT INTO Logger(IPAddress,Status)
VALUES (@strIP,'DELETE')
CREATE FUNCTION [dbo].[GetCurrentIP] ()
RETURNS varchar(255)
AS
BEGIN
DECLARE @IP_Address varchar(255);
SELECT @IP_Address = client_net_address
FROM sys.dm_exec_connections
WHERE Session_id = @@SPID;
Return @IP_Address;
END
but the problem is user can change data after disabling the trigger on specific table. so trigger will not fire and user can seamlessly change data.
so guide me what is the best way to capture data change and log them. so no one can bypass the security. please do not tell me disable sa account because i am looking for different approach to capture the change data. is there any secure way exist in sql
server 2005/2008 if yes then please discuss here. thanksIf you have shared SA password with different users you are bound to get these scenarios.Instaed of focussing on how to capture I would like you to talk with different users and only provide them access which is required.Follow policy f minimum privilege
your environement will be less complex .
You can use combination of Logon trigger and CDC to capture it.But again why o make things complex by sharing SA password with many users.

Export dump file and log file name as sysdate in script
Hi to All,
Can anybody help me to give logical backup export dump file namd log file name is as contain sysdate in its name so that we can Uniquelly identified it.
Regards
DXB_DBAOn windows it gets a bit hairy as there really is no clean and nice way of doing it.There are a couple of options.
1. If you can rely on dateformat not changing, you can use a static substring expression. For example, the following might work w/ finnish locale echo %date:~3,2%%date:~6,2%%date:~9,4%Similarly, when you know the dateformat you can tokenize the output of 'date /t' and discard the tokens you don't want.
2. You can set dateformat to your liking and then just use %date% in your script
3. You can run a "SELECT to_char(sysdate,..." into a file and then read that file in your script.
4. Simon Sheppard also has a solution you could use as a basis. I have a slight issue with the approach, but that could just be me.
5. Use gnuwin32 or similar ;)
Also note that %date% env var is set automatically from w2k onwards, so some of the solutions might not work w/ older versions. -

skiloHello ,
Please go through by support site :
Use SQL Server Enterprise Manager
Note The instance of SQL Server Enterprise Manager that is included with SQL Server 7.0 does not support setting the default data directory and the default log directory. However, you can register your instance of SQL Server 7.0 in the instance
of SQL Server Enterprise Manager that is included with SQL Server 2000, and you can then follow these steps to set the default data directory and the default log directory for your instance of SQL Server 7.0.
Click Start, point to Programs, point to
Microsoft SQL Server, and then click Enterprise Manager.
In SQL Server Enterprise Manager, right-click your instance of SQL Server, and then click
Properties.
In the SQL Server Properties (Configure) - <Instance Name> dialog box, click the
Database Settings tab.
In the New database default location section, type a valid folder path in the
Default data directory box and in the Default log directory box.
Click OK.
Stop your instance of SQL Server, and then restart your instance of SQL Server.

Urgent issues indicate a live/production system is having problems and a company is losing money, or customers are being prevented from using it.
For urgent issues you should raise your issue with Oracle Support using your customer support identifier.
The community forums are for non-urgent issues. To suggest such issues are urgent is considered rude, as the people who help here are volunteers with their own jobs to do, so demanding their time for your "urgent" issue is not appropriate. It also suggests that you think your issue is more important than other people's issues, so you are being rude to those people too. Your issue is no more important than anyone elses.
In relation to your question, you need to provide more information.
Please read: Re: 2. How do I ask a question on the forums?
When you refer to "SQL Server" are you referring to the Microsoft SQL Server product, or are you just referring to a physical server with your oracle database on it? -
DATE fields and LOG files in context with external tables
I am facing two problems when dealing with the external tables feature in Oracle 9i.
I created an External Table with some fileds with the DATE data type . There were no issues during the creation part. But when i query the table, the DATE fields are not properly selected though the data is there in the files. Is there any ideas to deal with this ?
My next question is regarding the log files. The contents in the log file seems to be growing when querying the external tables. Is there a way to control this behaviour?
Suggestions / Advices on the above two issues are welcome.
Thanks
LakshminarayananHi
If you have date datatypes than:
select
greatest(TABCASER1.CASERRECIEVEDDATE, EVCASERS.FINALEVDATES, EVCASERS.PUBLICATIONDATE, EVCASERS.PUBLICATIONDATE, TABCASER.COMPAREACCEPDATE)
from TABCASER, TABCASER1, EVCASERS
where ...-- join and other conditions
1. greatest is good enough
2. to_date creates date dataype from string with the format of format string ('mm/dd/yyyy')
3. decode(a, b, c, d) is a function: if a = b than return c else d. NULL means that there is no data in the cell of the table.
6. to format the date for display use to_char function with format modell as in the to_date function.

Shell Script to grep Job File name and Log File name from crontab -l
Hello,
I am new to shell scripting. I need to write a shell script where i can grep the name of file ie. .sh file and log file from crontab -l.
#51 18 * * * /home/oracle/refresh/refresh_ug634.sh > /home/oracle/refresh/refresh_ug634.sh.log 2>&1
#40 17 * * * /home/oracle/refresh/refresh_ux634.sh > /home/oracle/refresh/refresh_ux634.sh.log 2>&1
In crontab -l, there are many jobs, i need to grep job name like 'refresh_ug634.sh' and corresponding log name like 'refresh_ug634.sh.log '.
I am thinking of making a universal script that can grep job name, log name and hostname for one server.
Then, suppose i modify the refresh_ug634.sh script and call that universal script and echo those values when the script gets executed.
Please can anyone help.
All i need to do is have footer in all the scripts running in crontab in one server.
job file name
log file name
hostname
Please suggest if any better solution. Thanks.957704 wrote:

It's like you just walked into a hardware store and asked where they keep the fresh produce.
I will point out one thing about your question. You are assuming every entry in the crontab has exactly the same format. consider this crontab:
#=========================================================================
# NOTE: If this is on a clustered environment, all changes to this crontab
# must be replicated on all other nodes of the cluster!
# minute (0 thru 59)
# hour (0 thru 23)
# day-of-month (1 thru 31)
# month (1 thru 12)
# weekday (0 thru 6, sunday thru saturday)
# command
#=========================================================================
00 01 1-2 * 1,3,5,7 /u01/scripts/myscript01 5 orcl dev
00 04 * * * /u01/scripts/myscript02 hr 365 >/u01/logs/myscript2.lis
00 6 * * * /u01/scripts/myscript03 >/u01/logs/myscript3.lisThe variations are endless.
When you get to an appropriate forum (this on is not it) it will be helpful to explain your business requirement, not just your proposed technical solution. -

EXPDP generates new dmp file and reports "file already exists" error
Hello everyone,
Hope you all had a wonderful holiday. I got some problems with datapump expdp 10.2.0.4. It would be appreciated if you could provide some advice. Thanks in advance.
I newly created a 10.2.0.4 database. The database can startup and be connected via Toad without problem. I can also use impdp to import some data to the new database. But when I'm trying to use expdp to export a schema from the database, I got the following errors:

Every time I run the expdp, it just creates the dmp file (expdp_scott_mfp1_12262011.dmp) specified in the parfile under the EXPORT directory and reports "file already exists " error.
Your advice is highly appreciated.
Thanks.
Edited by: 904668 on Dec 27, 2011 8:47 AMi thought I found the problem. Used same file name on dump file and log file. How stupid of me. Sorry for bothering. Thanks and happy new year!

Do we need to format data and log files with 64k cluster size for sql server 2012?
Does this best practice still applies to sql server 2012 & 2014?Yes. The extent size of SQL Server data files, and the max log block size have not changed with the new versions, so the guidance should remain the same.

SQL Server 2012 installation and to default user database files to a particular path
Hi, I am working on SQL Server 2012 installation on one of our test boxes and I would like to configure the sql server install binaries and all the system databases but for tempdb to be in my C and tempdb on a different drive and once all this is set up,
whenever a developer creates a new database without specifying the path for the mdf & ldf files. They should be defaulted to a path like "D:/Data file" & "D:/Log file" for instance instead of being created on the C drive.
Thanks in advance.........
IoneHi,
You can of course set default location of database through management Studio please refer below link. Once you change default location even if you do not specify location it would take default one.
http://sqlandme.com/2013/03/18/sql-server-changing-default-database-location-for-server/
I would advise you not to keep files on C drive let it be dedicated system drive also its quite possible that SQL server service account would not have privilege on C drive so after you move tempdb SQL server would not come online as tempdb files cannot
be created . Tempdb is always recreated after SQL Server starts so you just need to change location once using Alter database command
See example mentioned in below link for how to do that
