Shrinking database file

Hi experts,
According to the reference guide(4.9 Diskspace Requirements), BDB does not return the freed space to underlying file system by deleting entries. And it also says that we need to create a new database and copy the records from the old one into it.
Followings are my questions...
Q1. In case of BTree, there is 'compact' api. Which one is better in performance of other view points between using 'compact' and copying into new DB?
Q2. Is it the only way for Hash?
Q3. The guide also saying that pages that key/data pairs are deleted from, can be reused where possible. Is there any criteria or rule for reusing it or not? Can we control it?
Q4. What about with in-memory configuration? Are these same?
Thank you.

Hello,
First SQL server 2000 is totally outdated and is no longer supported in any kind by Microsoft.
>>However, in the Recovery option if I switch it to simple and then shrink the database it will shrink
Shrinking of database is most evil operation you can do in SQL Server it causes massive fragmentation so please don't do it.You can go for data file shrink IF THERE IS GRAVE requirement to shrink it.SQL server data file might not
always respond to shrink command as release space.From what you posted seems like you are trying to shrink log file .You cannot shrink log file if last Virtual Log file( VLF) is still required by some transaction.To make sure it is marked as reusable you need
to take log backups at frequent interval ONLY LOG backup can truncate the logs and make VLF reusable and then you can shrink( A long running transaction can still hold VLF hostage and wont allow it to be marked as reusable).
When yo change recovery model to simple you force checkpoint which causes VLF to truncate and thus you can free space.

Shrink Log file in log shipping and change the database state from Standby to No recovery mode

Hello all,
I have configured sql server 2008 R2 log shipping for some databases and I have two issues:
can I shrink the log file for these databases: If I change the primary database from full to simple and shrink the log file then change it back to full recovery mode the log shipping will fail, I've seen some answers talked about using "No
Truncate" option, but as I know this option will not affect the log file and it will shrink the data file only.
I also can't create maintenance to reconfigure the log shipping every time I want to shrink the log file because the database size is huge and it will take time to restore in the DR site, so the reconfiguration
is not an option :(
how can I change the secondary database state from Standby to No recovery mode? I tried to change it from the wizard and wait until the next restore for the transaction log backup, but the job failed and the error was: "the step failed". I need
to do this to change the mdf and ldf file location for the secondary databases.
can any one help?
Thanks in advance,

1. If you change recovery model of database in logshipping to simple and back to full Logshipping will break and logs wont be resored on Secondary server as log chain will be broken.You can shrink log file of primary database but why would you need that
what is schedule of log backup. Frequent log backup is already taking care of log files why to shrink it and create performance load on system when log file will ultimately grow and since because instant file initilaization is not for Log files it takes time
to grow and thus slows performace.
You said you want to shrink as Database size is huge is it huge or does it have lots of free space. dont worry about data file free space it will eventually be utilized by SQL server when more data comes
2. You are following wrong method changing state to no recovery would not even allow you to run select queries which you can run in Standby mode. Please refer below link to move Secondary data and log files

Shrinking a database file

Hello everybody,
I want to shrink a database file (temporary file from temporary tablespace). How can I do that either with SQL Plus either with Oracle DBA Studio. I have Oracle 8i.
Thanks.

I would say "Yes" for shrinking unless space is your major constraint.
Definitely you can shrink the files but emptying a file requires lot of page movement, Its going to halt your database for a while. This is going to cause the issue.
If you check the extent usage of each file using
dbcc showfilestats
and then use the corresponding file where it requires shrinking
DBCC shrinkfile(fileid,target_size)
This is going to online operation and you can stop the process whenever you want.

Shrink Log File on High Availability

Dear support
good day for you,
i using SQL server 2012 and using AlwaysON High Availability (server_SQL1 = Primary & Server_SQL2=Secondary), when i try to shrink the log files he told me you must alter the database to simple recovery mode first but i cant coz using AlwaysON !
thats mean:
remove the DB's from AlwaysON (Server_SQL1)
Shrink Files
remove DB's from Server_SQL2
add again DB's to AlwaysON
any other solution for shrink logs without add/remove DB from AlwaysON
Regards,

The link that Uri has is correct, but let me expand on it for anyone else that runs across this issue:
You don't actually need to be in the simple recovery model to shrink a file or the log. The reason why some people make the switch is because changing to the simple recovery model lets the database automatically clear the logs. This *generally* puts the
VLF in use at the very beginning of the log. Since shrinking a log file works differently from data files (log only works from the end of the log until the first used vlf) it allows for a fast shrink and grow operation to fix up the log.
In the full recovery model it is still possible, the difference being that you'll need to check to see which VLF the database is currently using and you may have to manually cause the log to circle around (by log backups, etc) to get a good shrink so
that you can grow at a proper size.

Shrink Log File on MS sql 2005

Hi all,
My DB has a huge logfile, with more than 100gb.
The idea is to shrink it, but the good way.
I was trying this way:
use P01
go
backup log P01 TO DISK = 'D:\P01LOG1\P01LOG1.bak'
go
dbcc shrinkfile (P01LOG1,250) with no_infomsgs
go
The problem is that the backup file is getting bigger and bigger each backup.
So, my question is, how to shrink the logfile, correctly, with backup, but that backup should not increase but stay at the same level, overwriting the backups.
I have full dayly backup with data protector from HP, but it doesn't clean the log, and it isn't possible to shrink it.

What you want to do with the log backups depends on how you are going to recover the database in case the system/database loss and your backup schedule.
1. If you are not going to do point in time recovery then there is no point in taking a tran log backup to a backup file. You can change the recovery model of the database to "simple". If your recovery model is "simple" you don't have to take transaction log backups at all. The inactive transactions are flushed from the log automatically. You should still be taking full and differential backups so that you can atleast recover your database to last full backup and apply the latest differential backup.
2. If this is a production system then you should definitly be on "full" recovery mode and should be taking regular transaction log backups and storing them in a safe place so that you can use them to recover your system to any point in time. Storing the transaction log backup on the same server kind of defeats the purpose because if you lost the server and disks you will not have the backups either.
3. If you are in full recovery mode and lets assume that you run your transaction log backups every 30 mins then you need your log file to be of the size that can handle the transactions that happen in any given 30 to 60 mins.
There shouldn't be a need to constantly shrink log files if you configure things right.

MS_SQL Shrinking Log Files.

Hi Experts,
We have checked the documentation which have been received from SAP (SBO_Customer portal), Based on the Early Watch Alert.
AS per SAP requsition we have minimized the size of 'Test Database Log' file through MS_SQL Management Studio.(Restricted file size 10 percent, size 10 MB)
Initially it was 50 Percent, 1000 MB
Doubt is:
Is that any problem will occur in future regarding this changes of 'LOG FILES'.
Kindly help me.
Based on your reply ...
i will update in live production database....

The risk to shrink log file is fairly small. Current hardware and software has much better reliability than before. When you shrink your log file, you just lose some history which nobody even know there is any value in it.
On the contrary, if you keep very large log file, it may cause more troubles than doing anything good.
Thanks,

How to shrink database for the Oracle

Hi,
As you know, in the Sql server database there is a "shrink database" for the shrink the database space, but how to do that for the Oracle9i?
Any comments would be appreciated.
Thanks a lot

You will have to resize ur datafiles to shrink ur db. Here are the steps
1) select file_name,file_id,bytes from dba_data_files;
This will give u the current size of datafiles.
2) select file_id,sum(bytes) from dba_free_space group by file_id;
This will give u the free space in the datafiles. If the file_id is not listed in this query that means the file is fully occupied/used.
(used space = bytes col from query 1 - sum(bytes) col from query 2)
3) alter database datafile file_id resize ### ;
Enter the value you wanna resize based upon ur req. You cannot shrink the datafiles below the used space.

Does shrinking LDF file have any impact on restoration?

Right now my LDF file is almost 50GB. My database is only of 10 GB size.
Here are my questions:
1. Why is the LDF file so huge?
2. Is there any way to avoid the LDF file to grow so big?
3. If I use shrink, will I have any issue while I am restoring the database in the future.

Hi,
1. Can be many reason , do you take frequent transaction log backups.
2. yes by taking proper transaction log backup and putting correct and reasonable value of autogrwth for data and log file
3. No, not at all. Shrinking log file only removes free space.

How to reduce unused/available space in database file

our database is partitioned on monthly basis and i am seeing large amount (nearly 50-70%) of space available in the data files. These files are not expected to grow(in large amount) in future. So i want to remove the unused space. What is the reason for
that large amount of unused space and how to eliminate it? I tried shrinking the file which decresed the unused space to decent size but that resulted in fragmentation. To avoid fragmentation I rebuilded the indexes which again brought the unused space to
the original size.
Is there any way to find which table (which field ) is causing this.
thanks in advance,

hi Kalen,
I am using sql server 2008 . I ran the following query [borrowed from other online sources]to get used,unused space for the files.
--================query======================
select
[FileSizeMB]
=
convert(numeric(10,2),sum(round(a.size/128.,2))),
[UsedSpaceMB]
=

a.name,'SpaceUsed')/128.,2)))
[UnusedSpaceMB]
=
convert(numeric(10,2),sum(round((a.size-fileproperty(
a.name,'SpaceUsed'))/128.,2)))
[Type]
=
case
when a.groupid

then
when a.groupid

When I ran the query sugested by you, i observed that there is no much difference[less than 10] between row_reserved and row_used value and all the reamining columns are 0.
Any suggestion is appreciated

SQL and database file

Hello.(sorry for my english)
I have a legacy system , ported to opencobol that uses Berkeley DB. I can successfully open the database files using java both in windows and linux. However i want to create a web front end for the application.
Data is stored using strange cobol structures (most numbers are stored as text or 4 bits per digit) and other fancy stuff.. so custom parsers should be written. (dont rember BDB classes name for that)
I have been reading the documentation of Berkeley DB 12 hours totaly today but couldnt find answers to some questions...
Is it possible to attach the database to dbsql.exe (sqlite) server ?? I tried to do "attach "..pathtofile" as NULL ,but i get multiple databases specified and not supported and other stupid messages....
I think that what i tried propably doesnt make sense as collumns arent specified and nothing is in order this thing to work ..It is a simple Key value database.
So i am a little stucked here.
The only solution i can think is to synchronize with a relational Database. But i dont have triggers or nothing that helps....
Note that i want one way synchronization. The "other way" will have very limited tasks.
It seems to me that checking every x minutes if something changed using a cursor is a demanding task. So i am wondering.. Is there a way to track changes???
Thank you :)
Edited by: 843912 on 12 Μαρ 2011 7:13 μμ

Hello,
I am not sure I completely understand your question. If you are asking about importing
and exporting data from a Berkeley DB database into an Oracle DB Table in Berkeley DB
releases prior to 5.*, then this can be done with the Oracle OCI interface. If I am
misunderstanding the question, please let me know.
Thanks,

Finding whole mapping from database file - filesystems - logical volume manager - logical partitions

Hello,
Trying to make reverse engeneering of database files and their physical carriers on logical partitions ( fdisk ).
And not able to make whole path from filesystem down to partitions with intermediate logical volumes.
1. select from dba_data_files ...
2. df -k
to get the listing of filesystems
3. vgdisplay
4. lvdisplay
5. cat /proc/partitions
6. fdisk /dev/sda -l
   fdisk /dev/sdb -l
Problem I have is that not able to determine which partitions are consisten in logical volumes. And then which logical volumens are consisted in filesystem.
Thank you for hint or direction.

Hello Wadhah,
Before start the discussion let me explain I am newcommer to Oracle Linux. My genetic with dba experience of Oracle is from IBM UNIX ( AIX 6.1 ) and Oracle 11gr2.
First task is to get the complete picture of one database on Oracle Linux for future maintenance tasks and make database more flexible and
preparing for more intense work:
-adding datafiles,
-optimize/replace archive redolog files on separated filesystem from ORACLE_BASE
- separating auditing log files from $ORACLE_BASE to own filesystem
- separating diag directory on separated file system ( logging, tracing )
- adding/enlarging TEMP ts
- adding/enlarging undo
- enlarging redo for higher transaction rate ( to reduce number of switched per time perceived in alert_SID.log )
- adding online redo and control files mirrors
So in this context try to inspect content of the disk space from the highest logical level in V$, DBA views down to fdisk partitions.
The idea was to go in these steps:
1. select paths of present online redo groups, datafiles, controlfiles, temp, undo
   from V$, dba views
2. For the paths got from the step 1
   locate filesystems and for those filesystems inspect which are on logical volumens and which are directly on partitions.
3. For all used logical volumes locate the logical partitions and their disks /dev/sda, /dev/sdb, ...

How to query a database file on my hard drive?

Hi,
I have a filer called "server.dbs" on my hard drive. It is a database file. I use a simple program that allows you to view databases, and it loads up and I can traverse the database and see all the entries as any standard database.
So I figured that Java's ability to handle SQL would allow me to make a standard SQL statement querying the database, and be able to get the results. The software stores servers in SID fields, and the value is the port the server runs on. I want to make a simple query to select a server by SID, and print the port in which that server is running on.
So is there any way to, via my java application, load a database from a file (rather than a url) which has no authentication required, and simply make my queries directly to that file? If so, how?
Thanks!

Normal database access is via JDBC.
http://java.sun.com/docs/books/tutorial/jdbc/index.html
To use that JDBC driver is needed to access the database. Databases in wide usage all have one. It isn't clear from your posting that you have a common database though.

Hi K Nani,
From your error message
ora_01122:database file 8 failed cerification check
ora_01110:datafile 8:d:\oracle\sid\sapdata1\sr3_5\sr3.data5'
ora_01251:unknown file header version read for file number 8
Looks like Data file is corrupted.
You may refer SAP note 696141 - Composite SAP Note: ORA-01122
10. ORA-01251: Unknown File Header Version read for file number <file_id>
Reason: The file header cannot be correctly read.
Solution: If you use Oracle 9.2 on WINDOWS and if you already installed the database with Oracle 7.2 or lower, see Note 636466.
           Otherwise: Restore/recovery
Only solution here is restore the database from backup.
Alternate solution If it is a non-production system.
If the file is corrupted, then take the datafile offline and open the database.
Hope this helps
Regards,
Deepak Kori
