What happens to (just) the software availability in Ubuntu after EOL?

I’ve gone through a lot of articles, over this, throughout the internet and knows what EOL (End of Life) does to Ubuntu support and other things.

But my question is that whether someone has ever tried using it afterwards?

Let me present an example for explaining the situation :-

Ubuntu 14.04 LTS is about to reach it’s EOL in April 2019. If today I use the command :-

sudo apt-get update sudo apt-get install vlc

This will install VLC. But if I use this command after EOL, supposedly July 2019, will this command be still functional. For someone might be just interested in the very basic use of Ubuntu & it’s softwares like for multimedia, typing, managing data on PC (like movies, documents, music, videos), PDF (document) reading, browsing (obviously might be unsecured and prone to attacks due to lack of security updates).

I hope I’m making situation clear. In simple language, someone might not be interested in the very advance use of Ubuntu and just on very basic use for which he is not very concerned about the security patches and stuff.

Q. Will these usual commands still be functional and if not what could be done? Q. I read somewhere Editing :- /etc/apt/sources.list and change ‘archive.ubuntu.com’ to ‘old-releases.ubuntu.com’

Has anyone tried this method? Does it worked? What could be alternative.

Thanks

PS:- Else I’ve to, like before, rely on third-party softwares which could actually save the .deb files (to a definite location that can be even migrated) of the all the downloaded softwares, along with dependencies, and install it anytime without the internet.

Load balancing Availability groups with MSSQL Standard

So i have the current scenario, and it looks to be working fantastically, but i just want to get some input on the configuration. Is it smart? Are there any issues i am not thinking of?

We have MSSQL Standard, and as such, you can only have 1 DB per AG (we have 20 databases), and no Read-Only secondaries. Basically meaning, the primary server is doing ALL the lifting, with the secondary doing alot less. So essentially, you are paying for resources for Node 2, that are sitting at 10% workload, while node 1 is at 70/80% workload. Both nodes are fully licensed with regards to MSSQL Cores.

What i have done, to assist this, is slit the database primaries up. So about 50% of the databases are Primary on node1, while the other 50% are primary on node2.

The Results :

The applications all connect great to either node via their respective listener If a failover occurs, just the databases on the failing node are effected, and failover to the other node (We have tested this fairly well).

Each node, can now split the load, essentially load balancing. It is a manual process to set it up this way and when deploying new DB’s and groups they go to the lighter node. but a small price to pay for “more” hardware punch without much cost (Licenses which we already have and a bit of admin)

What are your guys thoughts on this?

Bundle/Configurable availability

there is a way to see the dinamic availability for bundle and configurable product?

ex:

configurable product X have in-stock availability;

associated product Y (associated of X) has out-of-stock availability;

associated product Z (associated of X) has in-stock availability;

i would that if i choose the associated prodcut Z remain in-stock availability, like configurable, but if i choose associated product Y the availability change to out-of-stock.

i use magento 1.9.3 theme ultimo

p.s. i try with configurable swatches, but the site slows down a lot

replication VMs in availability set

I have kind of a stupid question. I am starting to learn about MS Azure Cloud and planning on using an availability set in Azure. I understand that I need at least 2 VMs in my availability set. However, if I create a new VM, does it automatically replicate all the data and applications from the first VM, or do I need to find a way for that? Also, may I also use the VMs from my availability set for the autoscale? As it would be a great way to get better performance based on use and limit cost for availability and performance. I understand I would also need a load balancer if I use it this way.

Sorry for the bad question, I just cannot find the answer. Paul

Check windows remote desktop availability from command line

How can I check

  • from command line
  • whether a server accepts RDP (windows remote desktop) connections?
  • without using user/password login credentials

I am trying to run automated network sanity checks.
I know I can start a GUI remote desktop session to a host via

mstsc /v:<server_adress> 

but this opens a GUI window, whose result (OK or can’t connect via remote desktop) I yet can’t get back to my checker script.

oracle shard availability pending

Trying to adjust Oracle DB 12.2 sharding configuration. Have one DB as the shard catalog and other two DBs as shards. Just want to test this functionality so run the tree DBs on the same machine in the same ORACLE_HOME. Using composite sharding method.

All the things done according to the official documentation. GDSCTL> config shows nothing wrong as I can see. but:

GDSCTL>config shard Name                Shard Group         Status    State       Region     Availability ----                -----------         ------    -----       ---------- -------- ape002              shrdgrp_oper        Ok        Replicated  reg_oper   PENDING ape003              shrdgrp_arch        Ok        Replicated  reg_arch   PENDING 

Every time I try to redeploy I get:

GDSCTL>deploy deploy: examining configuration... deploy: requesting chunk deployment on shards in shardgroup 'shrdgrp_oper'  via GSM ... deploy: requesting chunk deployment on shards in shardgroup 'shrdgrp_arch' via GSM ... deploy: shards configured successfully GSM Warnings: shrdgrp_oper ape002:ORA-45598: Shard  is in converted state , it should be either "PRIMARY" or "PHYSICAL STANDBY".

And in shard catalog I get:

SQL> alter session enable shard ddl; ERROR: ORA-02521: attempted to enable shard DDL in a non-shard database 

Please tell me how to get it ti work.
