1458381	2019-02-18 01:44:00	I believe that I was having a problem with MongoDB . I went and used Terminal to remove it and then to reinstall it . I got rid of all the RED Xs (again) but the last lines here bother me after I re-installed it and then asked it to START and I got a "unrecognized service" on it . . . . . joseph@SurfersMintu1 ~ $ sudo service mongod start [sudo] password for joseph: mongod: unrecognized service joseph@SurfersMintu1 ~ $ mongod The program 'mongod' is currently not installed .

1458382	2019-02-18 05:04:00	Try sudo service mongodb start I got that answer from here: stackoverflow.com	Rod J (451)
1458383	2019-02-18 05:45:00	@ Rod: OK - I did that and I guess Mongodb fired up OK . . . . I ran "Top" and got a lot of stuff that was interesting and all, but wouldn't stand still to see if mongodb was running or not . But now - I got the RED X back again . I think there's something wrong with mongodb, since I've been 'playing' with it, things are good then bad then good again . . Coincidence? I think not . Wish I knew for a fact what 'mongodb' does . I'm going to Google that right now . Thanks so far . . . . . . . . . . . . . . . . . .	SurferJoe46 (51)
1458384	2019-02-18 06:06:00	All Right!!!!! Google may be your friend, but it sure can confuse me . . . . . . . . . . . . . Here's what Google got me: ################################################## ############################################## Introduction to MongoDB On this page Document Database Key Features MongoDB is an open-source document database that provides high performance, high availability, and automatic scaling . Document Database A record in MongoDB is a document, which is a data structure composed of field and value pairs . MongoDB documents are similar to JSON objects . The values of fields may include other documents, arrays, and arrays of documents . A MongoDB document . The advantages of using documents are: Documents (i . e . objects) correspond to native data types in many programming languages . Embedded documents and arrays reduce need for expensive joins . Dynamic schema supports fluent polymorphism . Key Features High Performance MongoDB provides high performance data persistence . In particular, Support for embedded data models reduces I/O activity on database system . Indexes support faster queries and can include keys from embedded documents and arrays . Rich Query Language MongoDB supports a rich query language to support read and write operations (CRUD) as well as: Data Aggregation Text Search and Geospatial Queries . High Availability MongoDB’s replication facility, called replica set, provides: automatic failover and data redundancy . A replica set is a group of MongoDB servers that maintain the same data set, providing redundancy and increasing data availability . Horizontal Scalability MongoDB provides horizontal scalability as part of its core functionality: Sharding distributes data across a cluster of machines . Starting in 3 . 4, MongoDB supports creating zones of data based on the shard key . In a balanced cluster, MongoDB directs reads and writes covered by a zone only to those shards inside the zone . See the Zones manual page for more information . Support for Multiple Storage Engines MongoDB supports multiple storage engines: WiredTiger Storage Engine (including support for Encryption at Rest) In-Memory Storage Engine MMAPv1 Storage Engine (Deprecated in MongoDB 4 . 0) In addition, MongoDB provides pluggable storage engine API that allows third parties to develop storage engines for MongoDB Wow! I never knew that I had scalable geospatial redundancies that are also pluggable with those pesky horizontal fallovers . What shards are these zones of residence? Got an English translation of that for me?	SurferJoe46 (51)
1458385	2019-02-18 07:08:00	Beats me what that is all about. I've never used mongodb myself, never even heard of it. What do you need it for?	Rod J (451)
1458386	2019-02-18 07:16:00	On the subject of "Top". I would install htop which is better than the bog standard top. Htop gives you colour output and you can press F3 to search for a program you want to monitor. It will then highlight the program in question at the top of the heap. Of course, you could always do a Ctrl-Esc to get the gui equivalent of top which is far easier to use and it doesn't need a terminal to run in.	Rod J (451)
1458387	2019-02-18 21:46:00	Beats me what that is all about. MongoDB Atlas Deploy a fully managed cloud database in minutes The best MongoDB experience. Access data directly from your frontend code, intelligently distribute data for global apps, trigger serverless functions in response to data changes, and much more. Some people just like to install all sorts of things. My brother used to be like that, interestingly he used to have a lot of issues with this PC too. Now he doesn't. (Either)	piroska (17583)
1458388	2019-02-18 23:33:00	Perhaps you should ask yourself what you installed that requires MongoDB.	KarameaDave (15222)
1458389	2019-02-19 06:24:00	So - it's a dependency? Cr@p! I have no idea what I got that requires MongoDB. I think the ONLY extra I put in is Pithos.	SurferJoe46 (51)
1458390	2019-02-19 07:08:00	I ran the following command to see what the dependencies of pithos are (bear in mind I'm running Kubuntu 18 . 04 here, your results may differ): rod@Core-i5:~$ apt-cache show pithos Package: pithos Architecture: all Version: 1 . 1 . 2-1 Priority: optional Section: universe/gnome Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists . ubuntu . com> Original-Maintainer: Luke Faraone <lfaraone@debian . org> Bugs: . launchpad . net/ubuntu/+filebug" target="_blank">bugs . launchpad . net Installed-Size: 430 Depends: python3:any (>= 3 . 3 . 2-2~), gstreamer1 . 0-plugins-good, gstreamer1 . 0-plugins-bad, python3-pkg-resources, python3-gi, python3-gi-cairo, gir1 . 2-gtk-3 . 0, gir1 . 2-gstreamer-1 . 0, gir1 . 2-gst-plugins-base-1 . 0 Recommends: python3-dbus, python3-pylast, gir1 . 2-appindicator3-0 . 1, gir1 . 2-keybinder-3 . 0, gir1 . 2-notify-0 . 7, gnome-icon-theme-symbolic Filename: pool/universe/p/pithos/pithos_1 . 1 . 2-1_all . deb Size: 77784 MD5sum: e096f13089042e9deaa74638c3f9e6c2 SHA1: d1650efe53eb14bb9dd88f4f65a62e4c6162eea6 SHA256: fe989808ebf9a9c36ed6cdc6a055f0f4f123669f1383a19f65 e10fac8ae96d54 Homepage: https://pithos . github . io/ Description-en: Pandora Radio client for the GNOME desktop Pithos is a cross-platform desktop client for the personalized web radio Pandora, supporting all important features the official Flash™ client has . .

Description-md5: 54e28eb5517f3d5d7ba624c393e40012 No sign of mongodb in the Depends or Recommends sections there . So, maybe mondodb is a dependency of something else you installed .	Rod J (451)
