## Indices
|
||||
|
||||
Facilitan la búsqueda de datos dentro de las tablas (Diccionario). Si no se
|
||||
cuenta con una estructura de índices se debe recorrer toda la tabla hasta
|
||||
encontrar el registro
|
||||
|
||||
### Indices en MyISAM
|
||||
|
||||
| ID | TITULO | AUTOR |
|
||||
| - | - | - |
|
||||
| 23-4567-8 | Cien años de soledad | Gabriel García Márquez |
|
||||
| 12-3456-7 | El Túnel | Ernesto Sábato |
|
||||
| 89-0123-4 | 1984 | George Orwell |
|
||||
|
||||
El índice crea estas tablas de referencia
|
||||
|
||||
| TITULO | Ref |
|
||||
| - | - |
|
||||
| 1984 | {3} |
|
||||
| Cien años de soledad | {1} |
|
||||
| El Túnel | {2} |
|
||||
|
||||
| AUTOR | Ref |
|
||||
| - | - |
|
||||
| Gabriel García Márquez | {1} |
|
||||
| George Orwell | {3} |
|
||||
| Ernesto Sábato | {2} |
|
||||
|
||||
| ID | Ref |
|
||||
| - | - |
|
||||
| 12-3456-7 | {2} |
|
||||
| 23-4567-8 | {1} |
|
||||
| 89-0123-4 | {3} |
|
||||
|
||||
- Siempre que se modifique una tabla, todos los índices se actualizan
|
||||
- A mayor cantidad de datos, mayor tiempo de ejecución
|
||||
- Crea una estructura separada para índices PK y no PK
|
||||
- La columna inicial del índice es ordenada y toma como referencia la
|
||||
posición de la fila de la tabla original
|
||||
- Implenta índices **HASH** y **B-TREE**
|
||||
|
||||
### Indices en InnoDB
|
||||
|
||||
La clave primaria es el índice
|
||||
|
||||
| ID | TITULO | AUTOR |
|
||||
| - | - | - |
|
||||
| **23-4567-8** | Cien años de soledad | Gabriel García Márquez |
|
||||
| **12-3456-7** | El Túnel | Ernesto Sábato |
|
||||
| **89-0123-4** | 1984 | George Orwell |
|
||||
|
||||
Si se utiliza otro campo como índice, la referencia de este va a ser la clave
|
||||
primaria
|
||||
|
||||
| TITULO | Ref |
|
||||
| - | - |
|
||||
| 1984 | 89-0123-4 |
|
||||
| Cien años de soledad | 23-4567-8 |
|
||||
| El Túnel | 12-3456-7 |
|
||||
|
||||
| AUTOR | Ref |
|
||||
| - | - |
|
||||
| Gabriel García Márquez | 23-4567-8 |
|
||||
| George Orwell | 89-0123-4 |
|
||||
| Ernesto Sábato | 12-3456-7 |
|
||||
|
||||
- La tabla se ordena automáticamente con la clave primaria
|
||||
- Tiene mayor desempeño en consultas buscando a través de clave primaria
|
||||
- En el caso de buscar en un campo que no seas llave primaria, el costo es el
|
||||
mismo que usando MyISAM
|
||||
- La tabla esta ordenada con la PK por defecto
|
||||
- Los índices que no son PK poseen estructuras separadas y toman como
|
||||
referencia el valor de la PK
|
||||
- Solo trabaja con **B-TREE**
|
||||
|
||||
> **HASH** y **B-TREE** son algoritmos de busqueda en listas ordenadas
|
||||
|
||||
## Arbol Binario
|
||||
|
||||
- Valores a la izquierda del nodo son menores
|
||||
- Valores a la derecha del nodo son mayores

## Administración de usuarios
|
||||
|
||||
Esto se puede realizar desde Workbench:
|
||||
|
||||
`-> Pestaña Administración -> Users and Privileges` Donde se pueden escoger
|
||||
los roles que se quieran asignar al usuario
|
||||
|
||||
### User Administrador Manual
|
||||
|
||||
```sql
|
||||
CREATE USER 'dbadmin-user' identified by 'dbadmin-password';
|
||||
GRANT USAGE ON *.* TO `%`@`%` IDENTIFIED BY 'dbadmin-password';
|
||||
GRANT ALL PRIVILEGES ON *.* TO 'dbadmin-user'@`%` WITH GRANT OPTION;
|
||||
FLUSH PRIVILEGES;
|
||||
```
|
||||
|
||||
### Usuario con privilegios para schema `schema1`, uso local
|
||||
|
||||
```sql
|
||||
CREATE USER 'basic-admin' identified by 'basic-admin-password';
|
||||
GRANT USAGE ON 'schema1'.* TO 'basic-admin'@'localhost' IDENTIFIED BY 'basic-admin-password';
|
||||
GRANT ALL PRIVILEGES ON 'schema1'.* TO 'basic-admin'@`%`;
|
||||
FLUSH PRIVILEGES;
|
||||
```
|
||||
|
||||
### Usuario con privilegios limitados
|
||||
|
||||
`SELECT`, `UPDATE`, `INSERT`, `DELETE`, `EXECUTE`, `LOCK TABLES`, `CREATE TEMPORARY TABLES` para schema `schema1`, uso local:
|
||||
|
||||
```sql
|
||||
CREATE USER 'limited-user' identified by 'limited-user-password';
|
||||
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE TEMPORARY TABLES, LOCK TABLES,
|
||||
EXECUTE ON 'schema1'.* TO 'limited-user'@'localhost'
|
||||
IDENTIFIED BY 'limited-user-password';
|
||||
FLUSH PRIVILEGES;
|
||||
```
|
||||
|
||||
### Usuario con privilegios solo lectura
|
||||
|
||||
Para todas los schemas con acceso remoto:
|
||||
|
||||
```sql
|
||||
CREATE USER 'limited-user' identified by 'limited-user-password';
|
||||
GRANT SELECT, EXECUTE ON *.* TO 'limited-user'@'%'
|
||||
IDENTIFIED BY 'limited-user-password';
|
||||
FLUSH PRIVILEGES;
|
||||
```
|
||||
|
||||
### Backup user
|
||||
|
||||
```sql
|
||||
CREATE USER 'backup-user' identified by 'backup-user-password';
|
||||
GRANT SELECT, RELOAD, LOCK TABLES, REPLICATION CLIENT ON *.* TO 'backup-user'@'%'
|
||||
IDENTIFIED BY 'backup-user-password';
|
||||
FLUSH PRIVILEGES;
|
||||
```
|
||||
|
||||
### Limitando accesos remotos
|
||||
|
||||
- `192.168.1.%`: 192.168.1.0 - 192.168.1.255
|
||||
- `192.168.1.1_`: 192.168.1.100 - 192.168.1.255
|
||||
- `cliente_.empresa.com`: clientXY.empresa.com
|
||||
|
||||
### Revocar todos los privilegios
|
||||
|
||||
```sql
|
||||
SHOW GRANTS FOR 'usuario'@'localhost';
|
||||
REVOKE ALL PRIVILEGES, GRATN OPTION FROM 'user'@'localhost';
|
||||
```

# Oracle Cloud Infrastructure
|
||||
|
||||
## Cloud Computing
|
||||
|
||||
Basicamente es el uso de servicio como servidores, almacenamiento, redes, bases
|
||||
de datos y otros recursos computacionales a través de internet.
|
||||
|
||||
|
||||
|
||||
### Beneficios de uso de la Nube
|
||||
|
||||
1. Costos
|
||||
2. Velocidad
|
||||
3. Escalabilidad
|
||||
4. Productividad
|
||||
5. Desempeño
|
||||
6. Confiabilidad
|
||||
7. Seguridad
|
||||
|
||||
### Tipos de Nube
|
||||
|
||||
- Nube Publica
|
||||
- Nube Privada
|
||||
- Nube Híbrida
|
||||
|
||||
### Tipos de servicios en la Nube
|
||||
|
||||
- **IaaS** Infrastructure as a Service
|
||||
|
||||
El tipo más común de servicio en la Nube.
|
||||
Bajo laaS, el proveedor de la Nube proporciona la infraestructura de TI, como
|
||||
servidores, almacenamiento y redes, y se paga de acuerdo al uso.
|
||||
La mayoría de los recursos de TI ofrecidos en el modelo IaaS no están
|
||||
pre-configurados, lo que significa que el consumidor tiene un alto grado de
|
||||
control sobre el entorno en la Nube. Él es quien debe configurar y mantener
|
||||
cualquier software que desee ejecutar sobre la infraestructura provista.
|
||||
|
||||
El IaaS ganó fuerza significativa en los últimos años, especialmente con
|
||||
startups y divisiones independientes de empresas más grandes que tuvieran un
|
||||
crecimiento rápido y busquen construir sus propias aplicaciones esenciales
|
||||
para el negocio, pero evitan la inversión y el mantenimiento que la
|
||||
infraestructura requerirá.
|
||||
|
||||
Además se trata de empresas que muchas veces buscan escalabilidad inmediata,
|
||||
ya que por el rápido crecimiento, necesitan estar preparados para lidiar con
|
||||
un volumen cada vez mayor de trabajo. Con IaaS existe la posibilidad de
|
||||
comprar un nuevo servidor virtual, instalarlo por cuenta propia y obtener esa
|
||||
capacidad adicional en una porción de tiempo mas pequeño.
|
||||
|
||||
- **PaaS** Platform as a Service
|
||||
|
||||
PaaS (que significa plataforma como servicio) es un modelo informático en el
|
||||
cual el proveedor de la Nube te asigna, configura y gestiona toda la
|
||||
infraestructura informática, como servidores, redes como en IaaS, así como
|
||||
sistemas operativos, bases de datos, herramientas de desarrollo y
|
||||
administración de empresas.
|
||||
|
||||
En otras palabras, en PaaS toda la configuración de la base de datos, la
|
||||
seguridad y las replicaciones son realizadas por el proveedor con pocos
|
||||
márgenes de configuración, diferente de IaaS, donde las principales
|
||||
configuraciones son hechas por el desarrollador, lo que hace que PaaS sea
|
||||
más costosa que IaaS.
|
||||
|
||||
PaaS es un ambiente de informático listo para su uso, una vez que los
|
||||
recursos y servicios ya están implementados y configurados. Los servicios
|
||||
informáticos PaaS incluyen aquellos que lo ayudan a desarrollar, probar y
|
||||
entregar aplicaciones de software personalizadas.
|
||||
|
||||
Los desarrolladores pueden crear sus aplicaciones rápidamente y un proveedor
|
||||
de la Nube configura y administra la infraestructura informática subyacente.
|
||||
El consumidor puede reemplazar todo el ambiente informático local por el de
|
||||
PaaS o usar PaaS para expandir su ambiente de TI y/o reducir costos con el
|
||||
ambiente en la nube.
|
||||
|
||||
- **SaaS** Software as a Service
|
||||
|
||||
SaaS es como un proveedor de la Nube que ofrece aplicaciones de software bajo
|
||||
demanda. En este modelo, el proveedor administra no solo la infraestructura
|
||||
sino también las aplicaciones de software y los usuarios que se conectan a
|
||||
la aplicación a través de internet.
|
||||
|
||||
El software se modela como un servicio de la Nube compartido y disponible
|
||||
para los usuarios como un producto. Los consumidores de la Nube tienen el
|
||||
control administrativo y de gestión limitado.
|
||||
|
||||
Un ejemplo bien conocido de SaaS es Spotify, que es un servicio de música de
|
||||
streaming, podcast y video que fue lanzado en Octubre de 2008 en Estocolmo,
|
||||
Suecia. Es el servicio de streaming más popular y mas usado en todo el mundo.
|
||||
|
||||
SaaS es esencialmente la entrega de aplicaciones directamente de la Nube para
|
||||
usuarios individuales. El hardware que procesa los datos como así también el
|
||||
sistema operativo y no le importará nada para los usuarios finales. que
|
||||
acceden a estas aplicaciones a través de una plataforma como Chrome, Firefox,
|
||||
Safari, Google Play o Apple Store.
|
||||
|
||||
Organizaciones de todos los tamaños han migrado a SaaS. ¿Y por que no?, Por
|
||||
lo tanto no necesitan invertir en mucho hardware y sistemas operativos caros.
|
||||
Además, no tienen que pagar un equipo de TI para mantener la infraestructura
|
||||
o solucionar problemas de las aplicaciones.
|
||||
|
||||
El proveedor de SaaS ofrece todo eso. En caso de no utilizar un proveedor de
|
||||
SaaS, las empresas necesitan comprar una licencia perpetua para ejecutar una
|
||||
aplicación de software en sus sistemas.

|
||||
### What is Cloud Shell?
|
||||
|
||||
```txt
|
||||
Cloud Shell is a free web browser-based terminal accessible from the Oracle Cloud
|
||||
Console that is pre-installed with a set of useful tools. Each user is provided a
|
||||
5 GB home directory which provides persistent storage for your files.
|
||||
|
||||
Cloud Shell allows you to perform tasks including:
|
||||
|
||||
* Writing Linux scripts for managing your Oracle Cloud Infrastructure (OCI)
|
||||
environment
|
||||
* Developing or running applications built using the OCI SDKs
|
||||
* Building and running docker containers
|
||||
* Managing your Oracle Cloud Infrastructure (OCI) Functions
|
||||
* Accessing public and private resources including:
|
||||
* Running OCI CLI commands to manage your resources
|
||||
* Accessing your Oracle Container Engine for Kubernetes clusters
|
||||
* Accessing your compute instances using ssh
|
||||
* Managing your Autonomous Databases
|
||||
|
||||
Your persistent home directory allows you to store scripts and files in your
|
||||
Cloud Shell which will be retained for your next session even if you exit or
|
||||
restart Cloud Shell. Those files live in your Cloud Shell environment and can
|
||||
not be accessed by other users.
|
||||
|
||||
The OCI CLI is pre-configured to run as you with all of the policies and
|
||||
privileges that have been assigned to you by your Administrator. No additional
|
||||
set up is required to use it.
|
||||
```
|
||||
|
||||
### Tools Available in Cloud Shell
|
||||
|
||||
```txt

|
||||
```
|
||||
|
||||
### Using the OCI Command Line Interface (CLI)
|
||||
|
||||
```txt
|
||||
Included in Cloud Shell is a current version of the OCI CLI. The CLI is a
|
||||
small-footprint tool that you can use on its own or with the Console to complete
|
||||
Oracle Cloud Infrastructure
|
||||
tasks. The CLI provides the same core functionality as the Console, plus
|
||||
additional commands. Some of these, such as the ability to write and run scripts,
|
||||
extend Console functionality.
|
||||
|
||||
Cloud Shell updates the version of the OCI CLI on a regular basis. This means you
|
||||
are always using the latest version of our tools. We also automatically configure
|
||||
your credentials when
|
||||
you launch Cloud Shell so no further setup is required to use the OCI CLI in
|
||||
Cloud Shell. Authentication happens automatically.
|
||||
|
||||
Hit return to run the oci command oci iam availability-domain list :
|
||||
|
||||
$ oci iam availability-domain list
|
||||
```
|
||||
|
||||
### Using the OCI CLI in Interactive Mode
|
||||
|
||||
```txt
|
||||
The CLI also has an interactive mode that simplifies your OCI CLI user experience
|
||||
with several new features, including command and parameter suggestions,
|
||||
auto-completion, and command reference information.
|
||||
|
||||
In interactive mode, suggestions will be made as you navigate the command line.
|
||||
For example, it can help find the right arguments for a command, and fill in
|
||||
ocids by allowing you to search based on display names.
|
||||
|
||||
An example of a command you can run is oci iam availablity-domain list.
|
||||
|
||||
To try that now, and go into interactive mode, type oci -i and then hit Return.
|
||||
|
||||
And then try the following:
|
||||
|
||||
1. Type in iam and then a space. The CLI will give you a list of choices.
|
||||
2. Type avail and then hit tab to autocomplete the command
|
||||
3. Type a space and then list and then hit return to finish the command
|
||||
|
||||
|
||||
Type oci -i to go into interactive mode:
|
||||
$ oci -i
|
||||

||||

|
||||
```
|
||||
|
||||
### Using Docker
|
||||
|
||||
```txt
|
||||
You can use Docker from within Cloud Shell to develop software.
|
||||
|
||||
Hit return to docker run hello-world:
|
||||
|
||||
$ docker run hello-world
|
||||
|
||||
Hello from Docker!
|
||||
This message shows that your installation appears to be working correctly.
|
||||
|
||||
To generate this message, Docker took the following steps:
|
||||
1. The Docker client contacted the Docker daemon.
|
||||
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
|
||||
(amd64)
|
||||
3. The Docker daemon created a new container from that image which runs the
|
||||
executable that produces the output you are currently reading.
|
||||
4. The Docker daemon streamed that output to the Docker client, which sent it
|
||||
to your terminal.
|
||||
|
||||
To try something more ambitious, you can run an Ubuntu container with:
|
||||
$ docker run -it ubuntu bash
|
||||
|
||||
Share images, automate workflows, and more with a free Docker ID:
|
||||
https://hub.docker.com/
|
||||
|
||||

|
||||

|
||||
```
|
||||
|
||||
### Supported Programming Languages
|
||||
|
||||
```txt
|
||||
We support the following programming languages in Cloud Shell so you can write
|
||||
your own applications:
|
||||
|
||||
* Java including multiple versions of Oracle Java as well as
|
||||
GraalVM Enterprise JDK 17
|
||||

### Using the OCI Software Development Kits (SDKs)
|
||||
|
||||
```txt
|
||||
The OCI Software Development Kits (SDKs) allow you to build and deploy apps that
|
||||
integrate with Oracle Cloud Infrastructure services. Each SDK provides the tools
|
||||
you need to develop an app, including code samples and documentation to create,
|
||||
test, and troubleshoot. In addition, if you want to contribute to the development
|
||||
of the SDKs, they are all open source and available on GitHub.
|
||||
|
||||
Cloud Shell installs and updates the version of the OCI SDKs on a regular basis.
|
||||
This means you are always using recent versions of our tools. We also
|
||||
automatically configure your credentials when you launch the Cloud Shell so you
|
||||
do not have to set up keys if you use the default authentication provider.
|
||||
|
||||
To get up and running quickly, you can look at the SDK Cloud Shell Quick Starts
|
||||
for each of the languages:
|
||||
https://docs.oracle.com/en-us/iaas/Content/API/Concepts/developerquickstarts.htm
|
||||
|
||||
|
||||
You can also find source and examples on GitHub for the SDKs.

||||
* Python: https://github.com/oracle/oci-python-sdk
|
||||
* Typescript/JavaScript: https://github.com/oracle/oci-typescript-sdk

|

|
||||
* Ruby: https://github.com/oracle/oci-ruby-sdk
|
||||
```
|
||||
|
||||
### Code Editor
|
||||
|
||||
```txt
|
||||
Cloud Shell integrates seamlessly with the OCI Code Editor, allowing you to edit
|
||||
code, modify scripts, and update service workflows directly from the OCI Console.
|
||||
|
||||
The Code Editor lets you browse, view, and edit files in your Cloud Shell home
|
||||
directory and provides a convenient way to perform common code updates for
|
||||
various services, including creating and deploying Functions, editing Terraform
|
||||
configurations used with Resource Manager stacks, and creating and editing an API.
|
||||
It offers the following capabilities that enhance your productivity:
|
||||
|
||||
* Built-in integration with OCI services, including Functions,
|
||||
Resource Manager, and Data Science
|
||||
* Access to Cloud Shell and 30+ cloud-based tools
|
||||
* Git integration and workspace management
|
||||
* Rich language support
|
||||
* Session continuity
|
||||
* Personalized user experience
|
||||
|
||||
You can access this from the View menu in the Cloud Shell window or directly from
|
||||
the Developer Tools icon in the Console header.
|
||||
```
|
||||
|
||||
### Configuring Java Versions
|
||||
|
||||
```txt
|
||||
You can use csruntimectl to configure your version of Java.
|
||||
|
||||
To see the set of available Java versions see `csruntimectl java list`.
|
||||
Your current JDK is indicated by an *.
|
||||
Hit return to list the JDKs available on this system:
|
||||
|
||||
$ csruntimectl java list
|
||||
graalvmeejdk-17 /usr/lib64/graalvm/graalvm22-ee-java17
|
||||
* oraclejdk-11 /usr/java/jdk-11.0.17
|
||||
oraclejdk-1.8 /usr/lib/jvm/jdk-1.8-oracle-x64
|
||||
|
||||
|
||||
You can then set the JDK version by using the command
|
||||
`csruntimectl java set <version from above>`
|
||||
|
||||
Hit return to show your current JAVA_HOME:
|
||||
|
||||
$ echo $JAVA_HOME
|
||||
/usr/lib64/graalvm/graalvm22-ee-java17
|
||||
```
|
||||
|
||||
### Transferring Files to and from your Cloud Shell
|
||||
|
||||
```txt
|
||||
In addition to creating new files and scripts, you can upload files to and
|
||||
download files from your Cloud Shell.
|
||||
|
||||
Under the tools (aka gear) icon on the top right corner of the Cloud Shell header
|
||||
are three options related to File Upload/Download:
|
||||
|
||||
* Download - allows you to transfer files from your Cloud Shell to your local
|
||||
computer
|
||||
* Upload - allows you to transfer files from to Cloud Shell from your local
|
||||
computer
|
||||
* File Transfers - allows you to view active and completed Uploads and
|
||||
Downloads
|
||||
|
||||
To Upload files, you can either drag an drop files into the upload dialog (or
|
||||
even directly into Cloud Shell) or use the file selection dialog to select
|
||||
individual files.
|
||||
|
||||
Try dragging a file into the Cloud Shell window to try to upload now.
|
||||
|
||||
To Download files, you will have to enter the path starting at your home
|
||||
directory in the dialog box. For example, if your file was in ~/temp/myfile you
|
||||
would enter temp/myfile.
|
||||
```
|
||||
|
||||
### Understanding Regions
|
||||
|
||||
```txt
|
||||
Your Cloud Shell host (and your home directory) live in the Home Region for your
|
||||
tenancy regardless of what region is selected in the region pull-down menu in the
|
||||
top right corner of the console. This allows your home directory to be available
|
||||
no matter what region you are operating in.
|
||||
|
||||
Your current region (the region you have selected in the pull-down) is used when
|
||||
accessing tenancy resources using the OCI Command Line Interface (CLI) or the OCI
|
||||
Software Development Kits (SDKs).
|
||||
|
||||
In the current Cloud Shell Session:
|
||||
|
||||
* Your Home region is us-phoenix-1
|
||||
* Your Console selected region is us-phoenix-1
|
||||
|
||||
|
||||
Note: The region used by the SDKs/CLIs is "sticky" based on what was selected in
|
||||
the console when your Cloud Shell was opened and persists as long as the session
|
||||
exists. You can identify what region is active by looking at the Cloud Shell
|
||||
prompt. It will look like:
|
||||
|
||||
<username>@cloudshell:<directory> (<region>)
|
||||
|
||||
If you want to change your region for the CLI/SDK:
|
||||
|
||||
* Select a new region in the Console region pull-down menu, near the top of
|
||||
the Console.
|
||||
* Close and reopen your terminal.
|
||||
```
|
||||
|
||||
### Understanding Network Access from your Cloud Shell
|
||||
|
||||
```txt
|
||||
By default, your Cloud Shell uses our Public Network which is provisioned with
|
||||
both a Service Gateway and additionally has egress to the internet. From your
|
||||
Cloud Shell Public Network connection, you can run OCI CLI commands to access
|
||||
tenancy resources and also reach public resources. The access to public resources
|
||||
allows you to perform tasks like using ssh to access public instances, managing
|
||||
public OKE Clusters and pulling from public git repositories.
|
||||
|
||||
If you would like to access resources which do not have a public IP, you can
|
||||
instead use a Private Network Connection. Using Private Network Access, you can
|
||||
connect to a subnet (assuming your administrator has granted you permission) that
|
||||
lives in your home region.
|
||||
|
||||
See:
|
||||
https://docs.oracle.com/en-us/iaas/Content/API/Concepts/cloudshellintro.htm#Cloud_Shell_Private_Access
|
||||
|
||||
Note: No ingress to your Cloud Shell Hosts (in either public or private networks)
|
||||
is supported.
|
||||
```
|
||||
|
||||
