db2 installation on Centos 6.0 - db2

To start with can DB2-C-Express 10.1 be installed on CentOs 6.0 ? I am trying with the Light version .
I tried installing it but I am unable to execute commands like ./db2sampl , ./db2 from the bin after the installation.
Any pointers ? Any good links with steps for installation ?
Thanks .

I'm familiar with the "full" versions of DB2. In general, the installer should have created an instance owner such as "db2inst1". Log in in that account and try it. the .bashrc file should already include include it. If you would like to run it from another account, source the db2profile file in the instance home:
. ~db2inst1/sqllib/db2profile
The other account would need the correct privileges to execute administrative commands.

Can I install postgresql without pgAdmin4?

I was packaging an windows application installer by NSIS.
An postgresql binary file was included in this install package.
But the official binary file is too large 172MB.
The zip archive is download from
https://www.enterprisedb.com/download-postgresql-binaries
The inside structure is like
pgsql
bin
doc
include
lib
pgAdmin4
share
StackBuilder
symbols
In my opinion, pgAdmin4 is no need for my installer.
There are only CRUD operations in between application and SQL.
If I remove this directory, the binary zip can down to 41MB.
So could I simply remove directory pgAdmin4 and re-compress
to achieve this?

Yes, and you can remove StackBuilder too if you want. Also symbols if you don't want to do in-place debugging if the postgres server crashes.
Please, please install your bundled PostgreSQL on a non-default port (not 5432) and if you run it as a service use a name associated with your application, so users know where it came from. See Installation of postgresql with NSIS . Put the PostgreSQL install directory within your app install directory.

pgadmin4 : postgresql application server could not be contacted.

I have installed PostgreSQL 9.6.2 on my Windows 8.1. But the pgadmin4 is not able to contact the local server. I have tried several solutions suggested here in stackoverflow, tried to uninstall and reinstall PostgreSQL 9.6.2 , tried to modify the config.py, config_distro.py, and delete the files in Roaming folder,i tried standalone pgadmin4 installation, but no success.However, in my local machine i am able to access the server using psql.exe and log as as superuser (postgres user). Can you please suggest any possible solutions to starting/running pgadmin4 ? Thank you.
I found the same issue when upgrading to pgAdmin 4 (v1.6). On Windows I found that clearing out the content inside C:\Users\%USERNAME%\AppData\Roaming\pgAdmin\sessions folder fixed the issue for me. I believe it was attempting to use the sessions from the prior version and was failing. I know the question was marked as answered, but downgrading may not always be an option.
Note: AppData\Roaming\pgAdmin is a hidden folder.
Start pgAdmin 4 as administrator.
Do the following steps:
Right click pgAdmin 4 icon
Select "Run As Administrator"
I had the same issue on Windows 10, with a new installation of PostgreSQL 10.
I solved it by including the path C:\PostgreSQL\10\bin ({your path to postgresql}\bin) to system environment variables.
To access environment variables: Control Panel > System and security > System or right click on PC, then > Advance system settings > Environment variables > System variables > Path > Edit.
I've been dealing with this for awhile (frustrating). So much that I have instructions on my desktop consolidating all of these ideas. Here is my magic combination to the solution:
Delete from App Data C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
Add to Path Variables C:\Program Files\PostgreSQL\9.6\bin (I actually added it to both user and system)
Right click and start as admin.
You don't have to do this every time but when it gets out of wack try these steps.
What finally worked was downgrading to pgadminIII-v.1.22:
It seems in most of the cases Postgres trying to use information from previous sessions to find/connect the server and failing. Clearing out the previous session info helped me, it is a combination of 2 already mentioned answers above:
Navigate to Postgres session's folder
C:\Users\YourUsernameOrAdmin\AppData\Roaming\pgAdmin\sessions
Delete all the data from this folder.
Start PgAdmin in administrator mode.
Cheers!
if you are using Mac OS X here is a fix:
Open terminal and run this command
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log restart
and for other OS just restart your Postgresql server, it will solve
Then start pgAdmin4, it will start as normal

Deleting the contents of C:\Users\%USERNAME%\AppData\Roaming\pgAdmin directory worked for me!
I had same issue on windows. I had v1.6 installed as well as v2.0. Uninstalling v1.6 allowed me to login.
I had the same problem, but running it as an admin worked.
Have you recently installed a new version of pgAdmin ?
This issue (and the misleading message) is simply due to the fact that old versions of pgAdmin are unable to read the settings saved by a newer version of pgAdmin !
Make sure you're starting the right version of pgAdmin (your shortcuts are likely to point to the old version !) and/or uninstall the old version: the upgrade wizard doesn't do it for you !
Deleting contents of folder C:\Users\User_Name\AppData\Roaming\pgAdmin\sessions helped me, I was able to start and load the pgAdmin server
I had the same issue on the macosx and I renamed .pgadmin (in /users/costa) to .pgadminx and I was able to start pgAdmin4.
In Windows Just go to this path and clear it
,that works !!
C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
I was able to solve the problem by changing the pgAdmin web interface port.
I believe this problem occurred on my computer because I have several other services consuming webs ports like qBittorrent, IDEJetbrains, etc.
Right-clicking on the pgAdmin logo near the clock is possible to configure it.
I Fixed it in windows 10 just running pgAdmin 4 as Run as Administrator .
If you use older postgresql version like 9.x and its services is running,PgAdmin 4 confused which server is base database.
So stop the service older version or new one.Run PgAdmin 4 as Administrator
Its worked for me
This is often a firewall problem. The firewall log then shows dropped packets between 127.0.0.1: and 127.0.0.1:, where the latter is the port shown in the Browser to get no connection with. This means, that the connection between pgAdmin client (high_port_1) and pgAdmin server (high_port_2) is blocked. Check your firewall log and if you find dropped packets like described, adapt your firewall settings accordingly.
If none of the methods help try checking your system and user environments PATH and PYTHONPATH variables.
I was getting this error due to my PATH variable was pointing to different Python installation (which comes from ArcGIS Desktop).
After removing path to my Python installation from PATH variable and completely removing PYTHONPATH variable, I got it working!
Keep in mind that python command will not be available from command line if you remove it from PATH.
I use the cmd prompt on Windows 10 with psql postgres postgres.
Then I launch pgAdmin4 and it works.
I had this problem with pgadmin4 v2.1 on linux fedora 27
Solved by installing a missing dependency:
python3-flask-babelex
Just click on that pgadmin 4 icon and run as administrator. Allow the access permissions. It will start locally.
I need to add this here because I've had several issues with this message. If you have recently upgraded to High Sierra you will find the latest (pgadmin 4.20) will keep appearing with the message "Application Server Could Not be Contacted". What this actually means on Macs is that python was unable to configure your environment in ~/.pgadmin
This directory stores all the things you setup and configure and even logs of what was ran on your user copy usage of pgadmin.
The way to fix this issue on High Sierra is down to sqlite3. If you look in that directory you'll see everything is stored in sqlite3 files.
When version 4.20 of pgadmin was released it was shipped with a version later than sqlite3.19 and the problem arises because High Sierra is shipped with sqlite3.19, so to fix this issue, you need to replace the old version of sqlite3 with the latest on your packager.
Now be aware, MacosX+ all use sqlite to store details for the majority of apps on your mac, so you'll need to make sure you do not just wipe the old version but you'll have to have both versions co-existing together in harmony to avoid anything major occurring on your mac.
1) download brew https://brew.sh/
2) update brew and upgrade brew to make sure it's up-to-date
3) brew install sqlite3
4) mv /usr/bin/sqlite3 /usr/bin/sqlite3.os
5) ln -s /usr/local/Cellar/sqlite/3.21.0/bin/sqlite3 /usr/bin/sqlite3
6) /usr/bin/sqlite3 -version (check version is later than 3.19)
You can now proceed to open up pgadmin as normal
Got this issue after I upgraded PostgreSQL 9.4 to 9.6. The 9.4 binary package had PgAdmin 3 while 9.6 came with PgAdmin 4. I resolved it after a clean installation (I completely uninstalled and reinstalled) of PostgreSQL.
However, under different circumstances, you could try running the pgAdmin 4 application as an Administrator. This should fix the error.
downloaded pgadmin 4 v2.0 and install it no problem atm on force installation. try it. that was solution for me.
For my case in Windows 10 for postgresql 10 version, it worked by changing SERVER_MODE to False in config_distro.py placed in web folder, as per these configuration settings: https://www.pgadmin.org/docs/pgadmin4/dev/desktop_deployment.html.
There are other settings mentioned in this answer (https://superuser.com/a/1131964) regarding python but I just changed SERVER_MODE and it worked.
Kill it in Windows Task Manager and then try again. It seems that there is some sort of a problem when accessing the server from different applications.
As for me on windows 2012r2 it's start to work only after I reinstall pgAdmin 4 to folder c:\pgAdmin4. With out spaces and any special chars.
And all so I give full permission to this folder in NTFS.
It worked for me after installing python2.7 for pgAdmin 4 v2
Happens mostly when you have multiple versions of pgadmin installed or while trying to upgrade. Even I tried everything from killing the "running PID on port 5432" to "changing the server mode". In my case I uninstall postgres and re-install it again on different port(5433).
Later, I opened it through cmd(right click on cmd and select "run cmd as an Administrator").

PostgreSQL reinstall : Failed to load sql modules into the database cluster

I tried to re-install postgresql 9.5.3-1 on my windows 7 without success. In fact, at each attempt, I have the message:
failed to load sql modules into the database cluster
then, I get the message:
Error running post install step. Installation may not complete correctly. Error reading C:/Program Files/PostgreSQL/9.5/data/postgresql.conf
I tried several attempts to solve this issue
change the installation folder
switch to 32-bit
reboot
clean the register before reinstalling
install as a postgres user as describe here (Failed to load sql modules into the database cluster during PostgreSQL Installation)
PS: installation language is French
I finally found a solution to my problem. I just installed postgres as a super administrator
Had same problem. Just double check permission for your data folder. I set full control to authenticated users and it installs correctly.
Same problem here.
In my case it was a backslash \ at the end of the password.

TIBCO MFT Server Installation

I've asked by manager to check and confirm where the TIBCO MFT is installed on IBM AIX server. I'm completely new to TIBCO and don't know what is the installation directory of this software.
Could somebody please help me to find where it is installed on AIX server.
If your server is configured properly, then you should have an environment variable called CFROOT set that points to the installation directory (execute a echo $CFROOT to see its value).
The installation directory can be set during the installation process to some arbitrary directory, so in theory it could be anywhere. The default however should be /mftps, other likely options include /opt/mftps, or /opt/tibco/mftps.
Althaf ,
You can use "find" command as well to search for mftps on Server to know the directory.

Execute php commands in WAMP environment

I'm new to working in a WAMP environment, in this case I'm using Easyphp, and I can't find how to execute php commands (like a simple php -v), like I would do for example when connecting to a server with SSH.
I have Easyphp installed, apache and mysql servers are on, and I created a virtual host using the module in the same folder where I'm trying to execute the php command (using the cmd tool in windows).
Is there any other way to do this? Is there a "console" just for that? Any help would be appreciated!
EDIT
OK maybe I should give a specific example of what I'm trying to do in case I didn't explain myself very well. I'm trying to follow this guide to getting started with Zend Framework, and in the very first step after downloading the files, it asks to "type" 2 commands:
php composer.phar self-update
php composer.phar install
Where do I exactly "type" those commands?
In windows you need to set up your path environment variable (if it hasn't already been done by the installer) so that it points to the correct location for the PHP executables. Refer to the documentation for EasyPHP to see if/how you need to do this.
Then, open a dos window, and cd into the directory for your project. Then you should be able to run the commands as shown.
