I am using oracle 10g forms. I want to copy a image saved in my PC to server. While I checked locally by using two destination of my pc it works fine.
Code is
the_command:= 'copy D:\WORKORDER\'||:title.filename||'_'||:title.page||'.jpg D:\vish\'||:title.filename||'_'||:title.page||'.jpg';
My server is linux based. So I used the command
copy D:\WORKORDER\'||:title.filename||'_'||:title.page||'.jpg \WEB\folder\WORK_ORDER\'||:title.filename||'_'||:title.page||'.jpg';
It is not copying image in my pc to serverlocation. I tried both forward and backward slashes. Please help
I'd say that you should install Webutil and use its CLIENT_HOST to do that.
Although Forms offers the HOST built-in, as 10g Forms application runs on the Application server, HOST affects files on the server - not locally, on your PC. Therefore, as I said - Webutil's CLIENT_HOST.

I am trying to backup one of my databases in PostgreSQL pgAdmin tool. I used this tutorial:
backup database with pgAdmin
After finishing that I want to have the file. In that tutorial it says that we can use the Storage Manager to download the backup file on the client machine. After that from this link I wanted to access the Storage Manager. It says that "You can access Storage Manager from the Tools Menu", but from my system there is not any option with that name:
What is the problem and how could I obtain the backup database file?
If you are not running pgAdmin4 in server mode, then there is no storage manager. The storage manager is only relevant when the computer from which you run the pgAdmin4 GUI is different from the computer where the pgAdmin4 app-server is running.
When you took the backup, you told it where to save the file although not in a very user-friendly way. It asks for a filename, and there are three dots you can click to browse for a directory into which to put the file. But if you don't avail yourself of the three dots, then you don't know where it is going to put the file, it just uses an apparently OS-dependent default and doesn't tell you what it is. I usually find in my "Documents" folder. (Well, I usually don't use pgAdmin4 in the first place as it makes everything harder than just using the command line is, but when I do use it...)
I have a bash script written for OSX that downloads many large .zip files, unpacks them, and writes the contents to a Postgres database.
I want to do this from an EC2 instance because the operation takes a long time.
I don't which AMI to choose, given that OSX is not an option.
Should I be doing this on Ubuntu?
You don't need to use an AMI you can use AWS cloud init for launching your bash script after your instance is launched and as far as operating is concerned i think any operating system is capable for doing things you mentioned in the question however, i would recommend to use Amazon linux because its more optimized for ec2
Good day,
Currently I use MS Access at home for several Databases (for personal use).
At work, I use PostgreSQL, which is infinity times better. I want to start using postgres for my personally used databases, but I don't know where to start.
I've tried reading the documentation, but still don't know how to start. I don't have a server at home; is it possible I can just make a local database/tablespace? Or would I have to host a virtual server?
Note that I am willing to use other open source databases if there is an easy option out there - MS access is just so... terrible.
Thanks,
So, it seems you have Windows at home. You just need to download full installer for PostgreSQL:
http://www.postgresql.org/download/windows/
After installation it will automatically add starting postgres server as a service on local machine. That means, server will always run in background, but you can disable that later, or just uninstall.
After that, you can use pgAdmin (included in default installation package) or other client tools to access the DB engine.
UPD in pgadmin, create connection with this settings:
'localhost' as hostname;
port - 5432;
user, database - postgres (for testing purpose only - you should create your own user and tables with restricted rights later).
Password for postgres (that is DB admin user) must be entered during installation process.
Server settings are stored somewhere here:
"C:\Program Files\PostgreSQL\9.3\data"
pg_hba.conf - Client Authentication Configuration File
postgresql.conf - Configuration File
I am trying to do a local installation of a large but simple installation PostgreSQL 9.3.2 to hold about 14 GB of data, currently in a CSV file. This is my first attempt to install any database other than SQLite. The installer is asking me questions that I do not know how to answer and that seem inappropriate for an installation that I do not want to make available to the internet. I expect to be interacting with it through the R package RPostgreSQL. The database will contain primarily US Census data that is publicly available for free, and so not a tempting target. For instance, the installer asks me what port to use, and seems to require that I set a password. I prefer to set it up with no internet or remote accessibility at all, even from me.
Could someone tell me or point me toward documentation for producing a strictly local installation with minimal irrelevant hoops to jump through, both on installation and on use? I did a series of searches on variant of PostgreSQL & “install locally” or “local installation” or “create local database”, etc. but these were unproductive.
This will be on an ancient but lightly rebuilt Compaq laptop, Intel Core 2 Duo, Windows XP OS with SP3.
Any help folks could offer much appreciated.
If you're looking for an install that doesn't run a server and listen on TCP/IP, it isn't really possible, because PostgreSQL is a client/server database that (on Windows) communicates with clients solely over TCP/IP.
A "local only" install is one where the TCP/IP socket listens only on localhost, i.e. 127.0.0.1.
If you were really keen, you could not install the Windows service for the server at all, and just grab the binaries. To use PostgreSQL you would then have to initdb a new database directory, and start PostgreSQL when you wanted it with pg_ctl. See the user manual for details on these commands. When running, PostgreSQL would still be a server listening on a TCP/IP port, there's just no way around that on Windows.
On UNIX systems PostgreSQL can listen on a unix socket (a bit like a windows named pipe). This is not supported by PostgreSQL on Windows. Even then, it still has to run a server.
If you're looking for something like an embedded, on-demand, or in-memory PostgreSQL that runs out of the client library, there is no such thing.
In order to take some development work home I have to be able to run a PostgreSQL database.
I don't want to install anything on the machine at home. Everything should run off the usb drive.
What development tools do you carry on your USB drive?
That question covers pretty much everything else, but I have yet to find a guide to getting postgresql portable. It doesn't seem easy if it's even possible.
So how do I get PostgreSQL portable? Is it even possible?
EDIT:
PostgreSQL Portable works. It's very slow on the usb-drive I have, but it works. I can't recommend doing constant development with it but for what I need it's great.
Perhaps if I pick up a full speed external drive I'll try out virtualization. Given the poor performance of just running the database off this drive, a full virtual OS running off of it would be unusable.
Here's how you can do this on your own:
http://www.postgresonline.com/journal/archives/172-Starting-PostgreSQL-in-windows-without-install.html
An alternate route would be to use something like VirtualBox and just install your development environment (database, whatever) on there.
There are 2 projects to try in 2014: http://sourceforge.net/projects/pgsqlportable/ and http://sourceforge.net/projects/postgresqlportable/?source=recommended.
I can't vouch for the second, but I'm using the first and it works right out of the box.
After unzipping using 7-zip (http://www.7-zip.org/download.html):
1) Run "start service without usuario.bat" ( english translation )
2) Then run "pgadmin3.bat"
The only minimal problem for me was that its in spanish. I've been able to change the language to english by following Change language of system and error messages in PostgreSQL. Using google translate the instructions are:
Description
This is a zip to automatically run postgresql 9.1.0.1 for windows. This version already has pgagent and pldebugger. To run must: 1) unzip
the zip 2) run the "start service without usuario.bat" found in the
pgsql directory within the folder you just unzipped. 3) Optional. If
you want to run the agent works postgresql (pgagent) should only run
the "start pgagent.bat" found in the pgsql directory inside the folder
you just unzipped. 4) Optional. To manage and / or develop the bd you
can run the pgadmin3.bat 5 files) Optional. To stop and / or restart
the server correctly use file "service without stopping usuario.bat"
usuario.bat or restart service without depending on the case.
Now option for Linux (file. Tar.gz). Postgresql portable Linux 9.2
Please use the tickets for your answer bugs.
Username: postgres Password: 123
Just a Note : on a new computer , to get pgadminIII working you may need to add a db. The settings are in attached screenshot.
Hope it helps.
I agree with virtualization solution, but maybe you can find useful this link from portable freeware collection, I have used this locally, not from usb though
1.download and extract : zip version
2.inside pgsql folder create data folder(put any name,I used 'data')
3.initalize data folder: c:\pgsql\bin\initdb.exe -D c:\pgsql\data -U postgres -W -E UTF8 -A scram-sha-256
4.to start/stop see next cmd code that I use (press any key inside it to stop)
c:\pgsql\bin\pg_ctl.exe -D c:\pgsql\data -l logfile start
pause
c:\pgsql\bin\pg_ctl.exe -D c:\pgsql\data stop
