I have mistakenly put my SQL data directory in the wrong folder and as such, the system DBs are located in the wrong directory, and hence, I want to move it to a different directory. I am going to move the data and log files for all my system DBs but I would like to know if it will move all the folders under MSSQL or do I need to perform some other steps as well? Please find below the folders that I can see under MSSQL.
In order to move system databases, not only you should move the files, but prior to it you should change their paths in system tables by using
ALTER DATABASE..MODIFY FILE
When moving master database you should also change the startup parameters in Configuration Manager, you should put there the new location of master files.
All this is described in Move System Databases article.
Note that if one day you'll need to rebuild your master, it will be put in the old location, so you cannot just get rid of DATA folder. And after rebuilding you'll need to move your system databases again.
This is to let you know the solution to my problem. I have successfully changed the data root directory by moving the data and log files for all the system DBs to the desired location.I also had to change the registry value for the SQLDataRoot directory to my desired location and modify the location of the server diagnostics file as per my cluster requirement. After all this, I have been able to successfully move the folder to the desired location. Thanks for all the help everyone.
Basically when creating new database, PostgreSQL make directory in "data/base" with OID.
Now I have a directory like this from my previous database, can i import this directory as a real database in pgAdmin?
I have a folder from my old database called 16384.I past it in my data/base folder but pgAdmin does not recognize it as a database.
I want to import it in my Pgadmin.
Is there any way to do this?
Thanks a lot.
no. you can't do it with pgadmin.
try starting postgres with your data_directory pg_ctl -D DIR_WITH_BASE_CATALOG. If you lucky to star it, you can try taking a full backup - if success, the directory is usable, if not, you would recommend asking experts to help you extract as much as possible. If you decide to use zero_damaged_pages or other advanced features you can irreversibly destroy data (if there still is what to destroy)
anyway, before you start, I'd recommend copying the whole data_directory to somewhere else, and trying to start cluster from copy, not original...
I am pretty new with postgresql and pgAdmin and I made a beginner error.
I changed the hard drive of my computer and unfortunately (and stupidly I really admit) I have not make a backup of my database in pgAdmin3 before. Is there anyway I can manage to transfer it back from my old hard drive to the new one?
I tried to copy the file "Data" of pgAdmin from the old hard drive to the new one but it did not succeed. Is there any hidden file that would retain information of my database still on the old hard drive?
If I re-install the old hard drive, would I be able to access the database back?
if anyone have any idea I would be really glad,
thanks
Do as "Richard Huxton" suggested, then
On Windows you need may need to set PG as a Service
Run the following on the command line (as adminstrator):
pg_ctl.exe register -N postgres -D "C:\Program Files\PostgreSQL\9.6\data"
Start the service
answer from:
Register and run PostgreSQL 9.0 as Windows Service
Three steps are required:
Copy everything in the data folder (base, global, ... pg_xlog, ...)
Make sure the permissions are right
Make sure you have the same version of the PostgreSQL binaries installed.
Then just point the configuration at it (data_directory) and start it up. If there are any problems, check the logs for details - it'll probably be permissions.
Sometimes it's convenient to do all this in a virtual machine if you have that sort of stuff set up already.
I have set up an instance of AD-LDS as in here
http://www.thegeekispeak.com/archives/28
and connected to it with Softerra LDAP Browser
What I don't know how to do is get the users stored in the AD-LDS "database" on my colleague's machine into my machine. Is there some export/import process? Do I do it from the LDAP browser or somewhere else?
If someone has done this and can tell me how it could save me a lot of time and I would really appreciate it.
A good tool to work with directories in general is Apache Directory Studio and the language used to export/import datas from one Directory to another is LDIF. Apache Directory Studio log all your operation on a Directory in LDIF format.
Another is to build your version of AD-LDS as a replicate of the one of your colleague's machine.
There isn't a way to copy the entire object including attributes like SID and Password. If you simply want to share data, you can create replicas and the instances will be in sync.
I have the following problem and I need to know if there´s a way to fix it.
I have a client who was cheap enough to decline buying a backup plan for his postgreSQL databases on the main system that runs his company and as I thought it would happen some day, some OS files crashed during a blackout and the OS needs to be reinstalled.
This client didn't have any backups of the databases but I managed to save the PostgreSQL main directory. I read that the databases are stored somehow inside the data directory of the postgres main folder.
My question is: Is there any way to recover the databases from the data folder only? I am working in a windows environment (XP service pack 2) with PostgreSQL 8.2 and I need to reinstall PostgreSQL in a new server. I would need to recreate the databases in the new environment and somehow attach the old files to the new database instances. I know that's possible in SQL Server because of the way that engine stores the databases but I have no clue in postgres.
Any ideas? They would be much appreciated.
If you have the whole data folder, you have everything you need (as long as architecture is the same). Just try restoring it on another machine before wiping this one out, in case you didn't copy something.
Just save the data directory to disk. When launching Postgres, set the parameter telling it where the data directory is (see: wiki.postgresql.org). Or remove original data directory of the fresh installation and place the copy in its place.
This is possible, you just need to copy the "data" folder (inside the Postgres installation folder) from the old computer to the new one, but there are a few things to keep in mind.
First, before you copy the files, you must stop the Postgres server service. So, Control Panel->Administrative tools->Services, find Postgres service and stop it. When you're done copying the files and setting permissions, start it again.
Second, you need to set the permissions for the data files. Because postgres server actually runs on another user account, it will not be able to access the files if you just copy them into the data folder, because it will not have permissions to do so. So you need to change the ownership of the files to the "postgres" user. I had to use subinacl for this, install it first, and then use it from command prompt like this (first navigate to folder where you installed it):
subinacl /subdirectories "C:\Program Files\PostgreSQL\8.2\data\*" /setowner=postgres
(Changing ownership should also be possible to do from the explorer: first you must disable "Use simple file sharing" in Folder options, then a "Security" tab will appear in the folder Properties dialog, and there are options there to set permissions and change ownership, but I wasn't able to do it that way.)
Now, if the server service can't start after you start it manually again, you can usually see the reason in the Event viewer (Administrative tools->Event viewer). Postgres will throw an error event, and inspecting it will give you a clue about what the problem is (sometimes it will complain about a postmaster.pid file, just remove it, etc.).
The question is very old, but I want to share an effective method that I found.
If you have not got a backup with "pg_dump" and your old data is folder, try the following steps.
In the Postgres database, add records to the "pg_database" table. With a manager program or "insert into".
Make the necessary check and change the following insert query and run it.
The query will return an OID after it has worked. Create a folder with the name of this number. Once you have copied your old data into this folder, the use is now ready.
/*
------------------------------------------
*** Recover From Folder ***
------------------------------------------
Check this table on your own system.
Change the differences below.
*/
INSERT INTO
pg_catalog.pg_database(
datname, datdba, encoding, datcollate, datctype, datistemplate, datallowconn,
datconnlimit, datlastsysoid, datfrozenxid, datminmxid, dattablespace, datacl)
VALUES(
-- Write Your collation
'NewDBname', 10, 6, 'Turkish_Turkey.1254', 'Turkish_Turkey.1254',
False, True, -1, 12400, '536', '1', 1663, Null);
/*
Create a folder in the Data directory under the name below New OID.
All old backup files in the directory "data\base\Old OID" are the directory with the new OID number
Copy. The database is now ready for use.
*/
select oid from pg_database a where a.datname = 'NewDBname';
As shown by move database to another hard drive. All we need to do is to modify the registry table and file permissions. By modifying registry table(shown in image 1), postgresql server know the new location of data.
modify registry
If you have issues with permissions or with stuff like icacls during installation to old data folder then try my solution from sister website.

I do so but the most tricky part was to change the owner permission:
go to services from administative tools
find postgres service and double click on it
at log on tab change to local system
then restart
