I have a task to install Oracle 11g on a centOS 8 using VM (i'm new to linux / oracle).
I downloaded the Oracle files and unzipped them, then I tried to ./runInstaller but I get an error and this is the full terminal with error:

DISPLAY not set. Please set the DISPLAY and try again.
Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:
- For csh: % setenv DISPLAY 192.168.1.128:0.0
- For sh, ksh and bash: $ DISPLAY=192.168.1.128:0.0; export DISPLAY
Use the following command to see what shell is being used:
echo $SHELL
Use the following command to view the current DISPLAY environment variable setting:
echo $DISPLAY
- Make sure that client users are authorized to connect to the X Server.
To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command:
% xhost +
To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as 'xclock':
% <full path to xclock.. see below>
If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance.
Typical path for xclock: /usr/X11R6/bin/xclock

I am using putty and Xming but I still get this error.
Make sure your putty session is connecting with "x-11 port forwarding"
Be sure after you set this that you scroll back up to 'Session' and then 'save'

Recently I am working on upgrading my opensips version manually from 2.2 to 3.3.
Upgradation is done from my side but in old opensips(2.2) I was able to show registered user(SIP) using opensipsctl ul show command but in new version 3.3 opensipsctl is deprecated(I guess not sure).
So I am trying to get details using opensips-cli but I didn't find out correct command for show register and show dump list, I try to follow below link but did not find correct command.
https://www.opensips.org/Documentation/Interface-CoreMI-3-0
Also, my opensips-cli -x command not working giving the below error. (mi_fifo module loaded correctly)
# opensips-cli -o output_type=yaml -x mi uptime
ERROR: cannot access fifo file /tmp/opensips_fifo: [Errno 13] Permission denied: '/tmp/opensips_fifo'
ERROR: starting with Linux kernel 4.19, processes can no longer read from FIFO files
ERROR: that are saved in directories with sticky bits (such as /tmp)
ERROR: and are not owned by the same user the process runs with.
ERROR: To fix this, either store the file in a non-sticky bit directory (such as /var/run/opensips),
ERROR: or disable fifo file protection using 'sysctl fs.protected_fifos=0' (NOT RECOMMENDED)
/tmp/opensips_fifo file also created correctly.
# ls -l /tmp/opensips_fifo
prw-rw-rw- 1 opensips opensips 0 Dec 29 06:52 /tmp/opensips_fifo
Using opensips-cli command I am able to create database and add table but not able to perform -x command.
Can anyone help me to find out a command for show register and show dump list also any suggestion related -x command not working on opensips-cli.
I had a similar error and i found the following:
if you state in the opensips-cli.cfg file that the fifo_file is located at /tmp/opensips_fifo, it will produce this error, try changing this setting to /var/run/opensips/opensips_fifo
I've been at it for days but could not solve my problem.
I am running:
mpiexec -hostfile ~/machines -nolocal -pernode mkdir -p $dstpath where $dstpath points to current directory and "machines" is a file containing:
node01
node02
node03
node04
This is the error output:

--------------------------------------------------------------------------
ORTE was unable to reliably start one or more daemons.
This usually is caused by:
* not finding the required libraries and/or binaries on
one or more nodes. Please check your PATH and LD_LIBRARY_PATH
settings, or configure OMPI with --enable-orterun-prefix-by-default
* lack of authority to execute on one or more specified nodes.
Please verify your allocation and authorities.
* the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base).
Please check with your sys admin to determine the correct location to use.
* compilation of the orted with dynamic libraries when static are required
(e.g., on Cray). Please check your configure cmd line and consider using
one of the contrib/platform definitions for your system type.
* an inability to create a connection back to mpirun due to a
lack of common network interfaces and/or no route found between
them. Please check network connectivity (including firewalls
and network routing requirements).

I have 4 machines, node01 to node04. In order to log into these 4 nodes, I have to first log in to node00. I am trying to run some distributed graph functions. The graph software is installed in node01 and is supposed to be synchronised to the other nodes using mpiexec.
What I've done:
Made sure all passwordless login are setup, every machine can ssh to any other machine with no issues.
Have a hostfile in the home directory.
echo $PATH gives /home/myhome/bin:/home/myhome/.local/bin:/usr/include/openmpi:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
echo $LD_LIBRARY_PATH gives
/usr/lib/openmpi/lib
This has previously worked before, but it just suddenly started giving these errors. I got my administrator to install fresh machines but it still gave such errors. I've tried doing it one node at a time but it gave the same errors. I'm not entirely familiar with command line at all so please give me some suggestions. I've tried reinstalling OpenMPI from source and from sudo apt-get install openmpi-bin. I'm on Ubuntu 16.04 LTS.
You should focus on fixing:

Im trying to run sqlplus from user oracle in linux, but i only get the following error.
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
[ sqlplus ] completed with error code: 1
I have tried to run ./oracle_env.sh as user oracle and have tried it as user root as-well, but when I run the sqlplus / as sysdba command logged in as user oracle I get the above message.
Did I miss something, am I on completely the wrong track?
Here is a full output that I used/got.
`su - oracle
cd /u01/app/oracle/product/11.2.0/xe/bin
./oracle_env.sh
sqlplus / as sysdba`
If /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh sets your ORACLE_HOME, and ORACLE_SID environment variables, you need to "source" it invoking it in the current environment) using the "dot" prefix:
. ./oracle_env.sh
In any case, looks like your environment variables (including LD_LIBRARY_PATH) may not be set correctly.
I have an arch linux setup and installed neo4j through the arch user repository (yaourt -S neo4j), and I'm able to run the web console fine (sudo neo4j console with seemingly normal output and full functionality), however when trying to start the server (sudo neo4j start), I encounter the following error message:
/usr/share/neo4j/bin/utils: line 345: [: -lt: unary operator expected
Using additional JVM arguments: -server -XX:+DisableExplicitGC -Dorg.neo4j.server.properties=/etc/neo4j/neo4j-server.properties -Djava.util.logging.config.file=/etc/neo4j/logging.properties -Dlog4j.configuration=file:/etc/neo4j/log4j.properties -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled
Starting Neo4j Server...cat: /run/neo4j/neo4j-service.pid: No such file or directory
process []... waiting for server to be ready. Failed to start within 120 seconds.
Neo4j Server may have failed to start, please check the logs.
rm: cannot remove ‘/run/neo4j/neo4j-service.pid’: No such file or directory
There's no delay before the error message is printed, so it seems to be something other than the timeout. I'm quite new to neo4j (I worked through a fair bit of the user manual using the web console, but no development or server config experience), so I'm not really sure what else might be relevant. I tried looking through the utils script and the error appears to be where it attempts to su neo4j, but it also seems to proceed to attempt to start the server. I also tried changing the port it's starting on as in this question, but no change. The only log I can find just has this over and over (with appropriate timestamps):
Oct 15, 2014 1:33:49 AM com.sun.jersey.server.impl.application.WebApplicationImpl _initiate
INFO: Initiating Jersey application, version 'Jersey: 1.9 09/02/2011 11:17 AM'
Any help at all would be appreciated!
EDIT:
The line 345 that it's failing on is the end of this snippet:
if [ $UID == 0 ] ; then
OPEN_FILES=`su $NEO4J_USER -c "ulimit -n"`
else
OPEN_FILES=`ulimit -n`
fi
if [ $OPEN_FILES -lt 40000 ]; then
From doing some echo debugging, it seems that su $NEO4J_USER is failing, probably because $NEO4J_USER is set to neo4j, a user that does not exist on my system. I tried setting that to root in one of the config files, but evidently that's not working properly. Arch is a continual learning experience for me, but I've not had to add a new user before to get software working.
The interesting line here is:
/usr/share/neo4j/bin/utils: line 345: [: -lt: unary operator expected
I assume that is caused by a wrong default shell for the neo4j user. What default is currently set for the neo4j system user? Try to switch that to bash. The startup scripts should work nicely with bash.
I'm setting up the Puppet Dashboard for the first time. I have it running with the passenger module in Apache.
sudo rake RAILS_ENV=production reports:import
When I run this command, the tasks appear in the dashboard as failed.
630 new failed tasks
The details for each failure look something like this:
Importing report 201212270754.yaml at 2012-12-27 09:21 UTC
Permission denied - /var/lib/puppet/reports/rb-db1/201212270754.yaml
Backtrace
/usr/share/puppet-dashboard/app/models/report.rb:86:in `read'

The report files were owned by puppet:puppet with a 640 permission by default.
I ran chmod a+rw on the reports directory, but I still get the same errors.
Any ideas on what I might be doing wrong here?
If you are running the puppet-dashboard server as root instead of as the puppet-dashboard user, you will see this error. My system is using /usr/share/puppet-dashboard/script/server on centos 6.4 using the puppet-dashboard-1.2.23-1.el6.noarch rpm from puppetlabs.

edit the file like above and then run the command
