I am getting ERROR: "(error) ERR unknown command 'XTRIM'" while running on redis-cli.

You should upgrade to redis 5.x
To do this first go to /tmp directory:
$ cd /tmp
Then download and make redis by source:
$ wget http://download.redis.io/releases/redis-5.0.5.tar.gz
$ tar xzf redis-5.0.5.tar.gz
$ cd redis-5.0.5
$ make
And then run redis-server:
$ src/redis-server

When using redis-cli, I can unregister a RedisGears registration like this:
127.0.0.1:16379> RG.UNREGISTER "0000000000000000000000000000000000000000-4"
OK
When running this command as an inline redis-cli command, it fails:
$ redis-cli "RG_UNREGISTER 0000000000000000000000000000000000000000-6"
(error) ERR unknown command `RG_UNREGISTER 0000000000000000000000000000000000000000-6`, with args beginning with:
$ echo "RG_UNREGISTER 0000000000000000000000000000000000000000-6" | redis-cli
(error) ERR unknown command `RG_UNREGISTER`, with args beginning with: `0000000000000000000000000000000000000000-6`,
How do I run RG_UNREGISTER as an inline redis-cli command?
Also:
redis-cli "RG.UNREGISTER" 0000000000000000000000000000000000000000-6
This will unregister a RedisGears registration as an inline redis-cli command:
$ echo "RG.UNREGISTER 0000000000000000000000000000000000000000-8" | redis-cli
This also works:
$ echo "0000000000000000000000000000000000000000-1" redis-cli -x "RG.UNREGISTER"
Has anyone installed/run ActiveMQ on IBM i and can help me with this?
Either the process does not run or gives ZipException.
I downloaded ActiveMQ 5.16.2 from ActiveMQ 5.16.2 (Apr 28, 2021) - Unix/Linux/Cygwin bundle
for installing on IBMi V7R3 and followed the official steps for installation mentioned on Version 5 Getting Started - 'Installation Procedure for Unix' section.
This is similar to installing on IBMi as mentioned in - Installing activeMQ on IBM i5 V5R4
On running the command ./bin/activemq start, the process starts but ends without actually running ActiveMq.
It shows below error on the console -
./bin/activemq: 001-0019 Error found searching for command whoami. No such path or directory.
Also the command ./bin/activemq status returns ActiveMQ not running .
When running the command ./bin/activemq console, the process starts but gives the same whoami error and ends with ZipException.
On Windows, I have been able to install and run successfully.
Has anyone installed ActiveMQ on IBMi and can help me with this?
You are missing the command
whoami
This is not a shell built-in, so you would need to add that package to your installation.
h/t to #nfgl for the pointer to the IBM OSS rpm repo. If you inspect their src.rpm, you'll see they patch the activemq script. Worth reviewing
SRC RPM calls for this dependency: coreutils-gnu

I'm running the following command:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
and getting this error:
sysctl: cannot stat /proc/sys/fs/inotify/max_user_watches: No such file or directory
I'm not sure what to do about this. I'm running WSL on Windows 10 Build 1709, OS Build 16299.309
max_user_watches was not implemented in 1709. It apperars to be fixed in 1803. For more details you can refer to this bug:
https://github.com/Microsoft/WSL/issues/1705
I am trying to delete some keys but cannot execute any redis-cli commands:
redis-cli --scan --patter 'assetInfo*' | xargs redis-cli del
The error is:
(error) ERR unknown command: redis-cli
I am using REDIS version 3.2.7. Does this version not support redis-cli?
What gives?
Update: When I do this without 'redis-cli' I get this:
Azure Redis Health Dev:0>--scan --pattern 'spout*' | xargs redis-cli del
ERR unknown command: --scan
The error you're getting is a Redis error, which means you're already connected (and probably inside the cli). redis-cli is a command line (i.e. shell) utility for opening a connection to Redis and running commands.
P.S. your --pattern switch is missing an "n"
TL;DR - Dockerized Ambari on Ubuntu 14.04 Docker container throws error upon startup with default configurations
I'm attempting to Dockerize an Ambari deployment to support running it along side my Hadoop containers. Here is my Dockerfile:

When I start the container I get the following error -

From reading the HortonWorks docs for deploying to Ubuntu 14.04, this should work:
Install Ambari on Ubuntu 14.04
I've tried to deploy with the embedded Postges as well as an external one with the same results.
One interesting note is that even with the error, Ambari appears to be up and I can login as the default admin/admin, but when calling `ambari-server stop' it says no process is running...
root#3e6d778b43f8:/opt/ambari# ambari-server stop

I'll replicate this setup on my Ubuntu box tomorrow and see if the same thing happens.
Thanks!

docker is running inside of a Vagrant Virtualbox instance (v1.8.1)
I had same problem with ambari-server inside docker on ubuntu 14.04. Could you try the following
Workaround the aufs problem
Inside /etc/default/docker add
DOCKER_OPTS="--storage-driver=devicemapper"
and restart the docker service. Note that after this all your images will disappear (http://muehe.org/posts/switching-docker-from-aufs-to-devicemapper/). Rebuild your images.
To be honest I'm not 100% sure if this part is really needed.
After switching from aufs to devicemapper you might get the following error:
ERROR: Could not find container for entity id
The solution was to remove the old AUFS db and any existing containers:
sudo rm -rf /var/lib/docker/containers/*
sudo rm -rf /var/lib/docker/linkgraph.db
Restarting your docker images/containers should now work on the devicemapper engine.
Put apparmor into complain mode for docker
Inside /etc/apparmor.d/docker comment out (#) line deny #{PROC}/{*,**^[0-9*],sys/kernel/shm*} wkx,, it somehow confuses apparmor utils. Than run
sudo aa-complain /etc/apparmor.d/docker
If aa-complain throws command not found, install:
sudo apt-get install apparmor-utils
After starting the container ambari-server started working for me.
I dont know how docker relies here on apparmor, i.e. what risks the operation above introduces...
It looks like there's an issue deploying Ambari to a docker container.. I broke it out and installed it onto a Vagrant 14.04 Ubuntu VM wit the following scripts:
install_java.sh
#!/bin/bash
echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections && \
add-apt-repository -y ppa:webupd8team/java && \
apt-get update && \
apt-get install -y oracle-java8-installer && \
rm -rf /var/lib/apt/lists/* && \
rm -rf /var/cache/oracle-jdk8-installer
install_ambari.sh
#!/bin/bash
export DEBIAN_FRONTEND=noninteractive \
&& wget -nv http://public-repo-1.hortonworks.com/ambari/ubuntu14/2.x/updates/2.2.0.0/ambari.list -O /etc/apt/sources.list.d/ambari.list \
&& apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD \
&& apt-get update \
&& apt-get -y install ambari-server
Followed by:
sudo ambari-server setup -s -v -j $JAVA_HOME
sudo ambari-server start -v
#thaJeztah - what do I need to fix with my Dockerfile setup?
