How can we change location of derby.log file in derby database?
Whenever derbynet.bat file is executed a derby.log file is created at its calling place, how can we change where the derby.log file is created?

I'm trying to open spatial data table and it is showing error:could not access file "$libdir/postgis-3": No such file or directory.
It is showing the same error while I'm taking backup of the Database
I have a web application querying a Postgresql database (successfully) and I'm looking to move the data folder from location /var/lib/postgres/9.3/main to a customisable location.
Right now I'm prevented from even copying the folder due to permission errors, but I can't assign myself the permissions because that breaks the postgres server.
(I broke the server by running sudo chown <username> -R /var/lib/postgres/9.3/main - which worked as a command but stopped the postgres server from working)
I would simply create a new folder and change the location there, but I'll lose the current instance of my database if that was done.
How can I move the current folder to a new location, so that I can point to it in the .conf file? I need to explicitly move the folder, I can't create a new DB.
You can just copy or move the directory, including all subdirs and files
cp -rp or mv should be enough for this.
Postgres must not be running while you are messing with the files
The base of the data-drectory (PG_DATA) must be owned by postgres and have file mode 0700 . (when not: pg will refuse to start)
[the rest of the files must at least be readable/writeble by postgres]
the new location must also be known to the startup process (in /etc/init.d/ and (possibly) in the postgres.conf file within the data directory. (for the log file location)
I have an Access 2007 database from which I call a Windows batch file to retrieve files from an external server via a ribbon menu. When executing the file manually everything works just fine. When executing the batch file via the Access ribbon menu the following error appears within the command line:
Opening data connection for ...
> Replace Existing File with Temp File:I/O Error
Binary transfer complete.
I've read something about this error in relation to (Admin) rights, but since the batch file actually runs when called by Access it not seems to be the issue.
How do I write a T-SQL backup database command to specify a file containing spaces?
Here is what I have:
BACKUP DATABASE AMDMetrics TO DISK = 'C:\Documents and Settings\daultrd\My Documents\DatabaseBackups\AMD_METRICS.DAT'
And this is the error I get:
Msg 3201, Level 16, State 1, Line 1
Cannot open backup device 'C:\Documents and Settings\daultrd\My Documents\DatabaseBackups\AMD_METRICS.DAT'. Operating system error 3(The system cannot find the path specified.).
Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.
Try sharing your intended destination folder and using a UNC path to backup from the server to your local machine.
BACKUP DATABASE AMDMetrics
TO DISK = '\\YourMachineName\SharedFolderName\AMD_METRICS.DAT'
This works for me, are you sure that the directory is correct?
backup database master to disk = 'c:\Test Me\master.bak'
Processed 41728 pages for database 'master', file 'master' on file 1.
Processed 5 pages for database 'master', file 'mastlog' on file 1.
BACKUP DATABASE successfully processed 41733 pages
in 22.911 seconds (14.230 MB/sec).
copy and paste this into explorer and see if you can get there C:\Documents and Settings\daultrd\My Documents\DatabaseBackups
This of course has to be the same machine, otherwise you need to map a drive to the location or use UNC paths
I was working through this issue as well.
It's possibly that the Service that SQL Server is running under (Network Service by Default) doesn't have permission to the folder specified.
BACKUP DATABASE master TO DISK = 'master1.bak' WITH INIT
The above should backup to the default backup folder
if that works with no problem it'll be the problem stated.
Where are log file stored in DB2?
I am searching for a file with name Updatedb20100604182008.log
from this page:
http://www.ibm.com/developerworks/data/library/techarticle/0301kline/0301kline.html
(The article goes into further detail about default locations as well.)
The database logs are initially
created in a directory called
SQLOGDIR, a sub-directory of the
database directory. You can change the
location where active logs and future
archive logs are placed by changing
the value for this configuration
parameter to point to either a
different directory, or to a device.
Archive logs that are currently stored
in the database log path directory are
not moved to the new location if the
database is configured for
roll-forward recovery.
Because you can change the log path
location, the logs needed for
roll-forward recovery may exist in
different directories or on different
devices. You can change this
configuration parameter during the
roll-forward process to allow you to
access logs in multiple locations.
The change to the value of newlogpath
will not be applied until the database
is in a consistent state. An
informational database configuration
parameter, database_consistent,
indicates the status of the database.
Note: The database manager writes to
transaction logs one at a time. The
total size of transactions that can be
active is limited by the database
configuration parameters:
The DB2 log file location can be found from the DB CFG parameter - 'Path to log files'.
The command would be the below, without an explicit connection to the DB.
db2 get db cfg for db_name | grep 'Path to log files'
Else, you can connect to the DB first and use the command as follows:-
db2 connect to db_name
db2 get db cfg | grep 'Path to log files'
db2 terminate
db2 connect to database
db2 get db cfg | grep -i log
cd /data/dblogs/NODE0000(path to the log files)
cd LOGSTREAM0000(these is log folder)
ls -altr(we can see all the log files with .log extension)
rm abc.log (give the log name which you want to delete)
