Fix PostGreSQL Database Hung During Drop or Alter Tables

Posted on March 23, 2020by joseph-shinaberry

You may find yourself in a situation where Postgres decides to stop responding after an Alter or Drop command was given in PGAdmin. This can be corrected by using the following commands below.

Shell into Postgres: 

psql

Select data from the pg_stat_activity table.

SELECT
  pid,
  now() - pg_stat_activity.query_start AS duration,
  query,
  state
FROM pg_stat_activity
WHERE (now() - pg_stat_activity.query_start) > interval '5 minutes';

Kill the zombie process after getting the PID exit Postgres and run:

sudo kill -9 <ProcessID>

                placeholder="Grader Name"
                :data="filteredDataArray"
                >
			</b-autocomplete>

Created: 

created() {
    this.getAllGraders();
    this.filteredGraders();
  },

Computed: 

filteredDataArray() {
      return this.gradersArray.filter(option => option
        .toString()
        .toLowerCase()
        .indexOf(this.testGrader.toLowerCase()) >= 0);
},

Data:

data() {
  return {
      graderList: [],
      gradersArray: [],
  };
}

Method (Get Data From Store):

methods: {
	getAllGraders() {
      this.graderList = this.$store.state.graders;
    },
    filteredGraders() {
      this.graderList.forEach((data) => {
        if (data !== null) {
          this.gradersArray.push(data);
        }
      });
    },
}

Sample data from $store:

[null,"Madge Calbreath","Jacquenette Romera","Frazier Harvison","Kennith Perford","Flory Castiglione","Kerri Fedoronko","Beauregard Northgraves","Terrel Giraths","Kenton Lickorish","Egbert Mallya","Axel Aldwich","Bria Rames","joe","Rhoda Lordon","Durant Shalliker","Christophorus Woodhouse","Creight Lennox","Gardiner Lauret","Rasia MacConneely","Shelby Antoniewski"]

Quick Guide – Setting Up Git For GitLab

Posted on March 7, 2020by joseph-shinaberry


Create a SSH Key:

$ ssh-keygen -o -t rsa -b 4096 -C "email@example.com"

Navigate to ssh directory. 

$ cd .ssh/

Concatenate your public key for GitLab

$ cat id_rsa.pub

Navigate to ssh directory.

Copy all the output [DO NOT CLOSE THIS WINDOW]: 

For example (Don’t copy this code):  
ssh-rsa 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 Your.Email@Here.com 

Upload your key to Gitlab by logging into your account and clicking your profile icon in the top the right corner, and click Settings then SSH Keys.

Next, you need to tell your local git that you have an active ssh directory, so while you are still in the .ssh directory type in: 

$ pwd

Copy the value that is output by that command. 

$ git config --system http.SSLCAPath <yourSSHDirectory>

Also if you are working in Windows Powershell Environment you may need to run the following command for Git to use SChannel, the built-in Windows networking layer. 

$ git config --global http.sslBackend schannel
