I'm trying to start Libreoffice impress automatically once my raspberry pi has started up.
I created:
.config/lxsession/LXDE/autostart
and added my presentation:
sudo libreoffice -show /home/pi/test.odp
When i execute the command in a terminal, all works fine.
However the autostart doesn't seem to work at boot. Libreoffice starts, but then says it can't find the file...
The file .config/lxsession/LXDE/autostart is used to start applications without root privileges. Therefore, you should remove "sudo" from your code:
libreoffice -show /home/pi/test.odp
That should work as intended. If your presentation need root privileges (I don't see why it would, but anyway), you could use gksudo on your code, then at boot you would see a window asking for your password to proceed. The new code would look like this:
gksudo libreoffice -show /home/pi/test.odp
Important: please note you should not try to open a GUI enabled application with sudo or root privileges, as this can have bad consequences, such as modifying permissions and ownership on program files, which could lead to malfunctioning. If you really need to open a GUI application as root, always use gksudo or gksu.
On the other hand, if you really need to open a program at boot with root privileges, you should look into using the file /etc/rc.local or the cron service for that.
i am trying to install jboss-fuse-6.1.0.redhat-379
and i am able to create esb:create-admin-user via console but not i am trying to automate installation via shell script .
i am able to start fuse server but not able to create user
esb:create-admin-user.
below is sample script for creating user.
!/bin/ksh
cd $HOME/jboss-fuse-6.1.0.redhat-379/bin
./fuse esb:create-admin-user --new-user admin1 --new-user-password admin12
but it is not creating user.
please let me know how i can do this .
This could be the issue with file write access present in etc .
Here is the another solution for that
Go to jboss-fuse-6.1.0.redhat-379/etc folder
Open users.properties file and add username=password,admin
Last word admin is the "Admin" role.
You are probably looking for the bin/client script to execute commands against a running fuse instance. But for that you will need a username/password ;)
If you want to automate it is indeed probably easier just to use #mahesh-biradar approach:
echo "admin1=admin12,admin" >> etc/users.properties
I am using helios Eclipse for debugging my code in postgresql.
My aim is to know how postgresql uses join algorithms during the join query, so I started to debug nodenestloop.c which is in the Executor folder.
I gave break points in that file, But whenever I try to debug that file, the control goes to main.c and never comes back,How do I constraint the control only to that particular file(nodenestloop.c)
Below are the following fields which I gave in Debug configurations of Helios Eclipse.
C/C++ Application - src/backend/postgres and
project - pgsql
I followed the steps given in the following link for running the program.
https://wiki.postgresql.org/wiki/Working_with_Eclipse#
I even uncheked the field "Start on Start up=main" , but When I do that, The step in and Step over buttons are not activated and the following problem has popped up.
Could not save master table to file '/home/ravi/workspace/.metadata/.plugins/org.eclipse.core.resources/.safetable/org.eclipse.core.resources'.
/home/ravi/workspace/.metadata/.plugins/org.eclipse.core.resources/.safetable/org.eclipse.core.resources (Permission denied)
So I started eclipse using sudo, but this time the following error has come in the console of eclipse.
"root" execution of the PostgreSQL server is not permitted.
The server must be started under an unprivileged user ID to prevent
possible system security compromise. See the documentation for
more information on how to properly start the server.
Could any one help me with this.
Thank you
Problem 1: User ID mismatch
Reading between the lines, it sounds like you're trying to debug a PostgreSQL instance that's running as the postgres user, or a different user ID to your own anyway. Hence your attempt to use sudo.
That's painful, especially when using an IDE like Eclipse. With plain gdb you can just sudo the gdb command to the desired uid, e.g. sudo -u postgres -p 12345 to attach to pid 12345 running as user postgres. This will not work with Eclipse. In fact, running it with sudo has probably left your workspace with some messed up file permissions; run:
sudo chown -R ravi /home/ravi/workspace/
to fix file ownership.
If you want to debug processes under other user IDs with Eclipse, you'll need to figure out how to make Eclipse run gdb with sudo. Do not just run all of Eclipse with sudo.
Problem 2: Trying to run PostgreSQL under the control of Eclipse
This:
"root" execution of the PostgreSQL server is not permitted. The server must be started under an unprivileged user ID to prevent possible system security compromise. See the documentation for more information on how to properly start the server.
suggests that you're also attempting to let Eclipse start postgres directly. That's very useful if you're trying to debug the postmaster, but since you're talking about the query planner it's clear you want to debug a particular backend. Launching the postmaster under Eclipse is useless for that, you'll be attached to the wrong process.
I think you probably need to read the documentation on PostgreSQL's internals:
Tour of PostgreSQL Internals
PostgreSQL internals through pictures
Documentation chapter - internals
Doing it right
Here's what you need to do - rough outline, since I've only used Eclipse for Java development and do my C development with vim and gdb:
Compile a debug build of PostgreSQL (compiled with ./configure --enable-debug and preferably also CFLAGS="-ggdb -Og -fno-omit-frame-pointer"). Specify a --prefix within your homedir, like --prefix=$HOME/postgres-debug
Put your debug build's bin directory first on your PATH, e.g. export PATH=$HOME/postgres-debug/bin:$PATH
initdb -U postgres -D $HOME/postgres-debug-data a new instance of PostgreSQL from your debug build
Start the new instance with PGPORT=5599 pg_ctl -D $HOME/postgres-debug-data -l $HOME/postgres-debug-data.log -w start
Connect with PGPORT=5599 psql postgres
Do whatever setup you need to do
Get the backend process ID with SELECT pg_backend_pid() in a psql session. Leave that session open; it's the one you'll be debugging.
Attach Eclipse's debugger to that process ID, using the Eclipse project that contains the PostgreSQL extension source code you're debugging. Make sure Eclipse is configured so it can find the PostgreSQL source code you compiled with too (no idea how to do that, see the manual).
Set any desired breakpoints and resume execution
In the psql session, do whatever you need to do to make your extension run and hit the breakpoint
When execution pauses at the breakpoint in Eclipse, debug as desired.
Basic misunderstandings?
Also, in case you're really confused about how all this works: PostgreSQL is a client/server application. If you are attempting to debug a client program that uses libpq or odbc, and expecting a breakpoint to trigger in some PostgreSQL backend extension code, that is not going to happen. The client application communicates with PostgreSQL over a TCP/IP socket. It's a separate program. gdb cannot set breakpoints in the PostgreSQL server when it's connected to the client, because they are separate programs. If you want to debug the server, you have to attach gdb to the server. PostgreSQL uses one process per connection, so you have to attach gdb to the correct server process. Which is why I said to use SELECT pg_backend_pid() above, and attach to the process ID.
See the internals documentation linked above, and:
PostgreSQL site - coding
PostgreSQL wiki - developer resources
Developer FAQ
Attaching gdb to a backend on linux/bsd/unix
I also faced similar issue and resolved it after some struggle
I misunderstood the following point under Debugging with child processes in the wiki (https://wiki.postgresql.org/wiki/Working_with_Eclipse).
5."Start postmaster & one instant of postgresql client (for creating one new postgres)"
The above step should be performed from terminal by starting postgres server and one client.
Hope this helps
Once this is done then debugger in eclipse needs to be started for C/C++ Attach to Application

I have googled about this and run the command 'regsvr32 vbscript.dll' and it shows the message 'DllRegisterServer in vbscript.dll is succeeded', but it haven't solved my issue.
Also I set the default value for {B54F3741-5B07-11cf-A4B0-00AA004A55E8} in registry to the file path of vbscript.dll, but it also haven't solved my issue.

Following link solve my issue
http://www.geekscribes.net/blog/2009/04/22/postgresql-database-cluster-initialisation-failed-solution/
The article text:
I’ll keep this one short and sweet. For those of you that have tried
to install PostgreSQL (mine was 8.3.7-1) on Windows Vista and got the
error Database Cluster Initialisation Failed error at the end of the
install, read this.
The problem is that Vista has some safety features associated with
setting permissions on the Program Files folder. Basically, even if
you are an admin, you can’t change permissions on some folders like
Program Files and Windows folder itself. This causes initdb to be
unable to create some folders and the database cluster. What this
means for you is that you need to install PostgreSQL in another folder
that is not inside Program Files.
By the way, if you have forgotten your Postgres account password while
installing the first time, just open a Command Prompt in Vista (If you
don’t know how, Google for it). Then type the command “net user”. You
will see a list of users on your computer. Find Postgre’s account.
It’s usually “postgres“. Then you need to change its password by
typing “net user postgres new_password” where new_password is… well, a
new password for the account. You will be needing that postgres
account during install. You will need admin privileges to do this
change however.
Firstly, uninstall any failed installations. Use the Control Panel or
the PostgreSQL installer in the install folder.
During the install, you will be prompted to choose where you want to
install the program. Just select a location in another place. Like
“C:\PostgreSQL” or something similar. It may even be on your desktop.
But not inside Program Files. Not inside Windows folder. However, it’s
not as easy. Bear with me.
After the install, you will still see that darned error message (or
something like non-fatal error occured). Do not despair! (For Windows
Power Users, we are just assigning Full Control permission to Postgres
account on the new PostgreSQL install folder). For other users, read
on if you don’t know how to do it.
Go to where you just installed PostgreSQL. In this case, the C:
drive. There, right-click on the folder (usually called PostgreSQL),
and go to Properties – Security tab. Click on the Edit button. You
will now see some usernames and other stuff. Click on the Add button.
In the “Enter the object names to select” box, enter “postgres” and
press Check. Postgres’ user account should appear there. Click on Ok.
Now from the “Group or Usernames” box, select the Postgres account. In
the window below, with lots of checkboxes, assign permission “Full
Control” in the Allow Column to it. Note, if you don’t want to allow
full control, just give it read/write. But I just went ahead and gave
it Full Control. (I was tired and annoyed. The “World’s most advanced
open source database” had failed to install!). Click on Ok and wait a
bit for permissions to be applied.
Then, just do a re-install. Do not uninstall anything. Just run the
setup again. It’ll say that a PostgreSQL install folder already exists
and other stuff. Just click on Next until the install finishes. If you
see “file cannot be copied” errors, click on the “ignore” button when
needed.
That’s it. PostgreSQL should be up and running on Vista now. Hope it
works for you too as it did for me, and that my guide is helpful to
anybody. If it works, or if you have other solutions, let us know.
Thanks for reading! :)
I got the same result installing "postgresql-9.2.3-1-windows-x64.exe" on Windows 7 Enterprise
and the problem get solved when I change the installation path.
Try to install into "c:\postgresql" instead of "c:\program files\Postgresql"
Good luck
For me the problem was that PATH variable did not have C:\Windows\system32 and so it did not find ICACLS command to change folder permissions. So the solution is to add C:\Windows\system32 to system PATH variable (if it does not contain it already):
Control Panel -> System -> Advanced System Settings -> Advanced -> Environment Variables
Under "System variable" find and select "Path"
Click "Edit..."
Now if value does not contain path to system32 append string ;C:\Windows\system32 (or wherever your windows path is)

Solution:
• Uninstall PostgreSQL
• Run command: net user postgres /delete
• Click: Control Panel -> User Accounts -> Configure advanced user profile properties -> delete all “Unknown User” instances that seem to be left from PostgreSQL installation.
• Run: compmgmt.msc -> Click Local Users and Groups -> Users -> New User… -> User name: postgres, Password: postgrespass -> Create
• Run: compmgmt.msc -> Click Local Users and Groups -> Users -> postgres ->Member of -> Add… -> Administrators -> OK
• copy the PostgreSQL installer postgresql-8.4.9-1-windows.exe to C:\
• Run: runas /user:postgres cmd.exe -> cd \ -> postgresql-8.4.9-1-windows.exe -> installed successfully without errors. Checked data folder and confirmed files created successfully.
• Run: compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Administrators -> Remove
• Run: compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Add… -> Power Users -> OK
Your Windows install is a little borked, and you will need to re-register the VBScript engine to get the installer to run.
Edit: I'm blind, the post author had already tried this.
See:

I had the same problem when trying to install PostgreSQL 9.3.5-3 on a Windows 7 x64 machine (not joined to a domain) in a folder, created on the root, with full access to everybody. The problem was solved by not using ä in my password, so avoid using non-English characters in your password.
This message still occurs in Postgres v9.3.1.1.
For me, the problem was running the installer under the "Administrator" account. This doesn't work. Run it under an administrator account, avoiding the built-in "Administrator" account.
I don't really know what it's usually called, but it's the one that already exists on a fresh install; the one that cannot be changed to a Standard User; the one whose profile is stored in C:\Users\Administrator. Turns out it was a bad idea using this account; learned it the hard way.
(Windows Server 2008 R2 64-bit)
Hey guys the answer is very simple just install postgresql on another folder outside program files. it prompts a non fatal error and proceeds to with the installation...
I have solved the same problem on Windows Server 2003 and postgres 9.2.9-3 by creating directory for installation beforehand, and giving full access on it to group "Users".
The answer is very simple, move the downloaded .exe file to some other folder . for ex: c:\postgres and try to install it.
your issue is due to some admin privilege issues
There seem to be many reasons cause the installation fail.
In my case, I'm using Windows 10 home edition, which has no advance user group control,
so a lot of solutions above doesn't work for me. And I guess this is why the installation fails.
What I do is just using BigSQL's installer instead of EnterpriceDB's installer,
Choose the second installer in posgresql download center
Or visit BigSQL directly.
After some struggle I came across this post. I struggled some more time and I think I finally figured it out with the help of all the invaluable input from my predecessors in this post.
My case
It's November 2018.
PostgreSQL 11.1 Winodws-x64 from EnterpriseDB as suggested by postgresql.org
Tried to install on Windows 10 (both Home and Professional)
I tried several constellations and boiled down the process to this:
Pre-installation
Uninstall any failed installations.
Add a local user "postgres" (lowercase worked for me) to your computer, assign a SIMPLE password and administrative rights. Do avoid special characters at all expenses, stick with english letters (upper and lowercase) and numbers only.
Add a folder on your computer OUTSIDE the "C:\Program Files" or Windows folder. I chose C:\PostgreSQL
Assign full control over the above folder to the postgres account.
Installation
Run the installer (postgresql-11.1-1-windows-x64.exe in my case)
use the above password and folder when prompted (not the default folder)
Post-installation
For security reasons you should now assign a proper password to the windows-user "postgres" and remove administrative rights from the account.
Test your installation by running pgAdmin and connecting to your server. However, the password for the postgres user you need to connect to the server will still be the simple one you used earlier. You may change it within pgAdmin by selecting the postgres database left, choose Tools -> Query Tool and type ALTER USER postgres WITH PASSWORD '4wligzo748o$%&'; or whatever. Execute with the flash symbol or F5.
But maybe this is wrong altogether and you should rather run a linux vm with postgreSQL server.
Struggling with this problem for days. Finally got help from the EDB team
My problem got solved by doing the following steps :
1) Open the command prompt and go to the following directory:
cd "C:\Program Files\PostgreSQL\10\bin"
2) Once you are inside this "C:\Program Files\PostgreSQL\10\bin" directory execute the following command:
.\initdb.exe -D "C:\Program Files\PostgreSQL\10\data"
3) At the end of this command you will be promoted to execute a pg_ctl command to start the Postgres cluster. Please execute the command and once you get a message as the server started you are all set to use the Postgres database.
Note: Instead of 10 user whatever version you have installed. If the pg_ctl command in the third step gives an error after running it in \bin directory, then try running it in \data directory. After the above process re-run the installer.
I know it is not the the solution but installing 32 bit of Postgres, worked for me
I had the same problem when trying to install PostgreSQL 9.6.2 on a Windows 7 32 bit machine,but i got solution,first just uninstall the installed postgres,then delete the postgres folder from 'c' drive,delete the entry from temp file which resides in "C:\Users\AppData\Local\Temp".Then again installed postgres 9.6.2 that installed successfully.
Had this same problem trying to install on my company computer (PC running Windows 7). If you are not admin on your computer, you need to install it within your personal "User" folder (not in the "Program Files" folder(s) at the root).
If you still can't access Postgres:
Once you'd installed it under your "User" folder, use the 'Run' program and type in "services.msc" and hit enter. In the window that pops up, go down to your postgres installation, right-click and go to "properties". In the "Log On" tab, select "Local System account" then go back to the "General" tab and click "Start". It should boot after that.
After this, I was able to run "pgAdmin" and access the database (after entering the password I used during installation).
I had the same problem today when installing postgres 9.6.19 on windows 10.
Solution: Neither the installation path nor the windows path variable may contain a blank! Near to the end of the installer log file (found in wondows %temp% dir with a name like bitrock_installer_16156.log) i found:
Script stderr: "\UnxUtils\usr\local\wbin\";"C:\Program" kann
syntaktisch an dieser Stelle nicht verarbeitet werden.
where the installation directory i set as well as my windows %PATH% variable contained
C:\Program Files\
Workaround:
open a command prompt as administrator and type:
set path=C:\WINDOWS\system32
PostgreSQL-9.6.10-1-win64-bigsql.exe
And then of course choose a path not containing a blank.
That did it for me.
I encountered an issue where a username with a space in it on windows fails the postgres installation.
To test:
Reinstalled windows 10 home (restored)
Made a user account without the space
Postgres installed successfully
Very frustrating...
check the services: if any folder there postgres related stop it, and change to disable mode.
check regedit: HKEY_LOCAL_MACHINE, HKEY_CURRENT_USER -> software -> remove postgres folder if exists.
In system environment variable: TEMP path location, remove the TEMP folder for both user and system. and Rename the TEMP to TEMP1 or something..
In system environment variable: remove path for postgres if it exists.
Now change the location of postgres.exe file to another drive.
Restart the system
Then Run postgres.exe
create a new installation directory for postgres and put /data outside.
the easiest way i solve this was:
1.- uninstall if you have already installed
2.- delete all files with failed instalations
3.- start windows in secure mode
4.- run installer in secure mode (it pops a warning but ignore) and restart
and that's it when restarted the service was running ok and everything works fine
