Not able to start Informix server - informix

I am new to Informix. I installed Informix in the folder - /opt/Informix_Software_Bundle.
I am using the following command to start Informix server.
cd /opt/Informix_Software_Bundle
sudo ./oninit -i
And I am getting the following error message.
Unable to read $INFORMIXDIR (/usr/informix).
So I tried to set the environment variable INFORMIXDIR in ~/.profile as given below:
export INFORMIXDIR="/opt/Informix_Software_Bundle"
I also tried the following command:
INFORMIXDIR=/opt/Informix_Software_Bundle;export INFORMIXDIR
I tried logging out and in again. But nothing helped.
I will greatly appreciate if somebody can help me with this. Thanks for reading.
System - Mac OS Sierra
Informix version - 12.10

There are a number of environment variables used by the Informix server which include:
INFORMIXDIR : points to the directory where the product is installed. Add $INFORMIXDIR/bin to $PATH.
ONCONFIG : indicates the name of the main server configuration file in $INFORMIXDIR/etc. If not specified this will default to "onconfig."
INFORMIXSERVER : indicates the name of the Informix instance to connect to and refers to the DBSERVERNAME or a DBSERVERALIAS entry in the onconfig file referenced by $ONCONFIG.
INFORMIXSQLHOSTS : indicates the full path name of the communications configuration file used by Informix clients and servers. This will include an entry for the name specified by $INFORMIXSERVER. If this environment variable is not specified it defaults to $INFORMIXDIR/etc/sqlhosts.
Just having some or all of these environment variables set is not sufficient for starting an Informix server from scratch. There are setup tasks such as editing the onconfig file to specify the location of the root chunk - this is the initial location where the server stores its data. For more details you might like to refer to the Informix online documentation:
Getting started with IBM Informix
Overview of database server configuration and administration
One of the most straightforward ways to get started is to use the demonstration server instance that may be created during installation. I'm not directly familiar with the Mac OS installation but for all other platforms the Informix installation process includes an option to configure and initialize a demonstration server, and I suspect Mac OS will be the same. This will create an environment file in $INFORMIXDIR which will include settings for the variables named above.
One word of caution: the oninit command is used to both start the Informix server and initialize the chunks where the data is stored. The -i argument will perform the complete disk initialization which is precisely what you want for the first time the Informix server is started. On subsequent restarts you would not normally use this argument or else all the data stored by the server may be lost.

As sudo by default resets environment variables it is usual to have
A) A script to set the required environment variables for a given server.
B) Another wrapper script to start/stop the server.

Why is my WSL2 enviornment referencing Java folder outside its virtual environment?

When I start my development rails server I get this following message first. To my knowledge WSL2 is a virtual environment.
I would have expected it to now reference a Java directory that resides on my Windows host. Is this likely something I carried over in the project from when I was using WSL1? How would I safely correct this?
/home/daveomcd/.rbenv/versions/2.6.1/lib/ruby/gems/2.6.0/gems/railties-6.0.3.2/lib/rails/app_loader.rb:53:
warning: Insecure world writable dir /mnt/c/Program Files (x86)/Common Files/Oracle/Java/javapath
in PATH, mode 040777
I experienced the same problem when trying to fix the slowness of WSL2. The recommended solution was to move the files from the mounted NTFS drive to the root ext4 filesystem (using \\$wsl\<distroname>), so I did that.
I set up /etc/wsl.conf as below:
# Enable extra metadata options by default
[automount]
enabled = true
root = /mnt/
options = "metadata,umask=0033"
mountFsTab = false
[interop]
enabled = true
appendWindowsPath = true
And ran rails bundle to update dependencies.
Also make sure that your file permissions and owner settings are updated. Hope it helps.
Sorry, I'd love to make this more of a comment to see if I'm on the right track before committing to an answer. However, since there's too much info here for that, I'll make an attempt at getting you an answer here.
While it is a virtual environment, by default WSL provides several "Windows Interop" features that allow it to:
automatically mount Windows drives in /mnt/{c,d,...}
append the Windows path to the Linux path
run Windows executables inside Linux
share Windows environment variables with Linux (although this is not something that happens by default)
I can't be sure (long, long time since I've used Rails), but it looks like something in the app_loader.rb is checking permissions on Java directories in the path. It may be using some logic like "check each path entry and look for a java or java.exe there. If found, check permissions." Or something like that. That means that (2) and (3) above may be confusing it.
You can see this in action with which java.exe, which will likely return a Windows path. Or run notepad.exe, which will launch the Windows Notepad executable from within Linux/WSL (magic! 😉).
These are both very useful features, so I hate to disable them completely, but it's the easiest way to figure out if that's the problem. Create a /etc/wsl.conf with the following contents:
[interop]
enabled=false
appendWindowsPath=false
Exit your WSL instance and then:
(from PowerShell, CMD, or Windows Start) Run wsl --list --verbose to see the name of your distribution (most likely Ubuntu)
Likewise, run wsl --terminate <distro> to terminate that distribution.
Restart your WSL instance
Try running /mnt/c/Windows/system32/notepad.exe (assuming a normal C:\Windows installation) (should fail, since interop is disabled)
Try which notepad.exe (should fail, since the Windows path should no longer be appended to the Linux path)
Try to start your Rails dev server again - Might work (might not, I could easily be wrong about the root-cause here)
If it does work, then you can try to correct the situation with several less invasive methods than disabling those features entirely:
If you plan on only using WSL for your development, then you could remove the Windows JDK.
Or at least remove the Windows JDK from the PATH in Windows.
Or, if you want to keep it installed and in the Windows path, you could have a shell startup file (e.g. .bashrc) that removes it from the path only in WSL. I'll point you to this question which contains multiple techniques for doing so.
Or you could keep the appendWindowsPath=false in your /etc/wsl.conf but then add back in the paths you want manually in your startup config.

How to install WebLogic AdminServer and NodeManager as windows service?

I am trying to install Weblogic adminserver as windows service but getting "Input too long" error while executing the install script.
I have struggled a lot in this issue and finally got the way to register AdminServer and Nodemanager as windows service for Weblogic. Below are the steps and issues faced with the progress:
To register weblogic AdminServer as windows server first need to create a script which will contain values like oracle home, java home etc. Below is the script I have used to install the service:
`
echo off
SETLOCAL
set MW_HOME=C:\Oracle\Middleware\Oracle_Home
set DOMAIN_NAME=osb_domain
set USERDOMAIN_HOME=C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain
set SERVER_NAME=AdminServer
set WL_HOME=C:\Oracle\Middleware\Oracle_Home\wlserver
set PRODUCTION_MODE=true
set JAVA_OPTIONS=-Dweblogic.Stdout="%USERDOMAIN_HOME%\stdout.txt" -Dweblogic.Stderr="%USERDOMAIN_HOME%\stderr.txt"
set WLS_USER=weblogic
set WLS_PW=Password123
set MEM_ARGS=-Xms1024m -Xmx1024m
call "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain\bin\setDomainEnv.cmd"
call "C:\Oracle\Middleware\Oracle_Home\wlserver\server\bin\installSvc.cmd"
ENDLOCAL
`
By running this script I was not even able to install the windows service as it was throwing " Input is too long" error and the reason is windows char limitations. You might get confused by classpath and will try to resolve classpath but
the issue is with JAVA_OPTIONS values which is set by SetDomainEnv.txt is creating this issue.
I have modified the script like below and shorten the JAVA_OPTIONS values by calling SetDomainEnv.txt command just before setting JAVA_OPTIONS in the script.
This has overridden the lengthy value of JAVA_OPTIONS. Now I have succesfully installed the AdminServer as windows service.
`
echo off
SETLOCAL
set MW_HOME=C:\Oracle\Middleware\Oracle_Home
set DOMAIN_NAME=osb_domain
set USERDOMAIN_HOME=C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain
set SERVER_NAME=AdminServer
set WL_HOME=C:\Oracle\Middleware\Oracle_Home\wlserver
set PRODUCTION_MODE=true
call "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\osb_domain\bin\setDomainEnv.cmd"
set JAVA_OPTIONS=-Dweblogic.Stdout="%USERDOMAIN_HOME%\stdout.txt" -Dweblogic.Stderr="%USERDOMAIN_HOME%\stderr.txt"
set WLS_USER=weblogic
set WLS_PW=Password123
set MEM_ARGS=-Xms1024m -Xmx1024m
call "C:\Oracle\Middleware\Oracle_Home\wlserver\server\bin\installSvc.cmd"
ENDLOCAL `
Even the service is successfully installed, when I was starting it the service is stopped immediately and wasn't printing any logs as it was not connecting to AdminServer.
After a bit analysis I found that JAVA_OPTIONS values which I have overridden in my script is very much needed to invoke AdminServer.
I have run SetDomainEnv.txt in cmd prompt and copied thre JAVA_OPTIONS values.
As the service is already installed, I just copied the correct JAVA_OPTIONS values CMDLINE param in the windows service registry manually.
Server subsystem failed. Reason: A MultiException has 6 exceptions.
Server installed as Windows NT service with incorrect password for user weblogic. The password may have been changed since the server was installed as a Windows NT Service. Contact the Windows NT system administrator.
Note: No extra spaces or character is inserted in CMDLINE param.
Now everything is in place which is actually required to start the admin server. But when I start the service it is throwing some authentication error along with others in the adminserver.log file.
after a lot of analysis I found that is is not authentoication issue, the problem was with boot.properties file. boot. properties file was not read properly.
This answer is continuation of below one:
after a lot of analysis I found that is is not authentoication issue, the problem was with boot.properties file. boot. properties file was not read properly.
Now I would give some background- If the fusion middleware is installed as development mode the boot.properties files is created automatically inside Oracle_HOME\user_projects\domains\domainname\servers\AdminServer\security and if you look at this prop file you will find the password and username in encrypted mode.
If the fusion Middleware is installed as production Mode then everytime it will ask for password and username. to avoid this perform below steps:
manually create file under Oracle_HOME\user_projects\domains\domainname\servers\AdminServer\security\boot.properties like mention below:
username=weblogic
password=Password
Note: No spaces should be added and take care of file extension.
Now start weblogic from domain\bin\startWeblogic.cmd. This will encrypt you boot.properties file. check boot.proprties file if encrypted you are good to go.
Finally start the windows service whic is installed following above process. It should work fine.
=======================
About Node manager use installNodeMgrSvc from domain\bin. Again if you get input is too long error, you must shorten JAVA_OPTIONS and then carefully edit CMDLINE param in the windows registry.

Start neo4j server with other configuration file

I try to start neo4j on OSX and change the chosen configuration file. I'd like to start a test server for unit tests with a different port and a database, which shall be deleted while startup (I will solve the deletion part in a shell script, which should stop and start the server).
My problem is neo4j ignores the configuration file from the parameter. My call looks like this (from the terminal and the current folder is bin:
./neo4j start -server -Dorg.neo4j.server.properties=conf/neo4j-server-test.properties
The default configuration file is still chosen.
Thanks for your help
There are no 'ad hoc' arguments to the neo4j command script, so your arguments after start are ignored. You need to either make a modified version of the neo4j command script, or swap out neo4j-server.properties files.
You can use ineo to manage two or more Neo4j instances:
https://github.com/cohesivestack/ineo
You can specify the path to a folder containing a customized configuration file with an environment variable:
NEO4J_CONF=../conf neo4j start

Setting enviorment variables in Informix database to start

i have installed Informix database server(11.70) successfully.but get problems in starting the DB server.when i run it give me error.
Warning: could not access INFORMIXSQLHOSTS /opt/IBM/informix1/etc/sqlhosts.
How to create this sqlhosts file and what is the exact content of this file.in my etc directory i have some similar files named :
sqlhosts.cmsm.sample
sqlhosts.cmsm.sample.all
sqlhosts.cmsm.sample.client
sqlhosts.cmsm.sample.er
sqlhosts.demo
sqlhosts.ol_informix1170_1
sqlhosts.std
but there is no file named sqlhosts in /etc/ folder.please guideline how to prepare this file ??
I suppose you created the instance during the install process. From your file list I suspect that the name was "ol_informix1170_1". I'd say, but I cannot be 100% sure that in order to setup the environment for your Informix instance, you need (as a minimum) set the following:
INFORMIXDIR=/opt/IBM/informix1
INFORMIXSQLHOSTS=/opt/IBM/informix1/etc/sqlhosts.ol_informix1170_1
ONCONFIG=onconfig.ol_informix1170_1 #check if this file exists (in $INFORMIXDIR/etc)
INFORMIXSERVER=ol_informix1170_1 #check that this is the value of the SERVERNAME in the previous file
PATH=$PATH:$INFORMIXDIR/bin
export INFORMIXDIR INFORMIXSERVER ONCONFIG INFORMIXSQLHOSTS PATH

Windows x64 RabbitMQ install error with Erlang environment var (ERLANG_HOME)

I'm ask/answering this question because it hung me up & it's likely someone else will have the same problem.
Install of RabbitMQ x64 v2.8.6 on Windows Server 2008 x64.
After Erlang install using default install location to C:\Program Files\erl5.9.2, I'm attempting to start the server via running the rabbitmq-service.bat. Fail:
Please either set ERLANG_HOME to point to your Erlang installation
or place the RabbitMQ server distribution in the Erlang lib folder.
Problem is the .bat file does not have the correct subpath. with 5.9.2 (R15B02) version of erlang. My ERLANG_HOME directory is set correctly, but the script does not use it correctly for this version of Erlang, which, it appears to this Erlang noob to have a new subdirectory called "erts-5.9.2" which is causing the problems. Maybe someone intimate with these scripts can describe how to make this work correctly without the hack workaround I'm about to describe?
1- Set environment variable:
Variable name : ERLANG_HOME
Variable value: C:\Program Files (x86)\erl6.4
note: don't include bin on above step.
2- Add %ERLANG_HOME%\bin to the PATH environmental variable:
Variable name : PATH
Variable value: %ERLANG_HOME%\bin
This works well.
There are several RabbitMQ control .bat files on windows. Every one you use needs to get changed to reflect the Erlang path correctly. In this example, I'm editing the rabbitmq-server.bat because it's one of the easier ones... any of the .bat files you want to run will need this hack to get them to work, with the rabbitmq_service.bat file being the most involved to adjust.
editing that rabbitmq_server.bat file, you can see on about line 48 or so there's a check to see if the erl.exe is found, but the path isn't correct:
if not exist "!ERLANG_HOME!\bin\erl.exe" (
that path does not match the file structure for the 5.9.2 version of Erlang. I fixed this by simply removing this path check from about line 48 to 58, then, where the .bat actually makes a call to the erl.exe on about line 129 which reads:
"!ERLANG_HOME!\bin\erl.exe"
I simply hardcoded the path to my erl.exe:
"C:\Program Files\erl5.9.2\erts-5.9.2\bin\erl.exe"
With the pathing correct, the rabbitmq .bat files will run.
I had the similar issue, modifying ERLANG_HOME in .bat files did not work. Then I tried echo %ERLANG_HOME% in command prompt, that did not print the environment variable value(I could see that ERLANG_HOME environment variable has been created under advance system settings), that lead me to believe that I need to restart server for 64 bit installation of Erlang. After rebooting server, It worked like a charm. I hope this helps someone.
Just to share an up-to-date answer as of 2019: On Windows Server 2019, after setting up the environment variable, a restart is required to solve the problem.
I got into same kind of problem.
I solved it by doing three changes as given below.
Update Path variable "ERLANG_HOME" : "C:\Program Files\erl8.0" in Environment Variables.
Upadte "Path" variable "Path" : ";%ERLANG_HOME%\bin;"
Give urself FULL CONTROL permissions over "Program Files" in C drive.
It worked for me in this way.
This problem still occurs in Erlang 18.3 (erl7.3) and RabbitMQ 3.6.9 on Windows when upgrading from any older version of RabbitMQ to version 3.6.9. The solution as already stated here is to manually set ERLANG_HOME with 'setx -m ERLANG_HOME "C:\Program Files\erl7.3"' before starting the service.
What happens is that the RabbitMQ 3.6.9 installer removes the environment variable ERLANG_HOME from the system while removing the older version of RabbitMQ. Then, when it proceeds to the installation step, it does not put back the ERLANG_HOME variable. Then, the batch files that start up RabbitMQ cannot find Erlang. They try to find Erlang's home directory using "where.exe" but it always fails after an upgrade.
RabbitMQ's installer also does not kill all of the Erlang background processes, causing many of its files to be undeletable due to the Windows "file in use" problem. This leaves behind "files in use" in %APPDATA%\RabbitMQ and "C:\Program Files\RabbitMQ." These processes are "erl.exe," "erlsrv.exe," and "epmd.exe." The RabbitMQ installer should taskkill these processes after shutting down the RabbitMQ Windows service.
RabbitMQ is rather clunky on Windows.
Download Erlang or OTP - Only one Version of OTP should be installed
Download RabbitMQ installer
Install both exe file as Administrator
Set class path for Erlang. (Setting classpath is a bit troublesome, so follow these steps)
Set a new path with name ERLANG_HOME and value C:\Program Files\erl-23.1 (do not copy bin folder here)
Edit System "path" and add %ERLANG_HOME%\bin
Go to Start - Open rabbitmq command promt and run
rabbitmq-plugins enable rabbitmq_management
Navigate to localhost:15672
Use guest/guest to login
Interesting that this worked for you. There is record of a two bugs in Erl5.9.2 that cause an incomplete installation where %ERLANG_HOME%\bin is not installed.
Either of
* Installed 64bit erlang on 32bit machine
* "The program can't start because MSVCR100.dll is missing from your computer."
https://groups.google.com/d/topic/erlang-programming/wGtFLzapiQ0/discussion
Try 5.9.1 or any other version. They also mention making the future versions of the installer alert you if it fails.
I just had the same problem mentioned here. I installed otp_win64_R15B02 on a Windows 7 machine and everything worked perfectly, but I used the same installer on a Windows 2008 server and the bin directory was not created. I then uninstalled otp_win64_R15B02 and downloaded the otp_win64_R15B02_with_MSVCR100_installer_fix and the bin directory was created.
I suspect the reason it worked on my Windows 7 system is that I have Visual Studio installed and the required libraries were already available which allowed the otp_win64_R15B02 installer to work correctly.
Oh, and if you're installing Erlang to run RabbitMQ the RabbitMQ install will succeed with the broken installer but installing otp_win64_R15B02_with_MSVCR100_installer_fix after RabbitMQ will not work, just un-install and re-install RabbitMQ to resolve this.
Just give C:\Program Files\erl10.6\ not C:\Program Files\erl10.6\bin\erl.exe in the environment variable. If you open the server.bat file I came to know the issueenter image description here
I think this is encoding issue on windows.I see a correct value but I write echo %ERLANG_HOME% on console the value come with question mark. These steps fix it.
1.go environment variable window
2.edit ERLANG_HOME item
3.copy the value, open notepad and paste there
4.copy again on notepad and paste to edit window
5.apply and exit window
6.close command line tools and reopen
7.run rabbitmq bat file.
I solved it in a quick and dirty way,without naming path variables
I've opened the bat file and replaced every occurrence of
!ERLANG_HOME!\bin\erl.exe
with hard coded path for example might be diffrent path for you because of diffrent version
C:\Program Files\erl10.3\erts-10.3\bin\erl.exe
and replaced
%RABBITMQ_HOME%\escript\rabbitmq-plugins
with
C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.14\escript\rabbitmq-plugins
Even I was this problem. The issue was the environment variable ERLANG_HOME=c:\Program Files\erl9.0 which was never existed.
I cross checked the path. The correct path was c:\Program Files\erl9.3.
After correcting the
ERLANG_HOME=c:\Program Files\erl9.3
the problem solved. So, definitely it is a path issue.
In my case, it should be installed erlang using admin role running
If above solutions doesn't work for you then you can try following
Find another compatible version of erlang for your rabbit mq e.g. for rabbit 3.7.x erlang version 20.3.x to 22.0.x all are compatible .
Right click newly downloaded erlang version and from properties select the option to unblock the file .
Run the erlang with admin persssion .
Re run rabbit mq exe
