Working in Markdown

I prefer to write my documents in Markdown these days. I wrote my recent blog on  using it. It helps me focus on the content rather than the formatting. I won't dwell to long on the ins and outs of Mark Down since there's huge amount of content on the web already. A quick Google search will provide a good start. However the reference I keep going back to is , because it's clean and in a form I find easy to parse.
The workflow I use for writing a document starts in 
. A tool more typically used for developing code, which I use it for too. Being able to use the same tool just means there one less application I need to keep up to date. However it's not the only reason. The primary reason is that VSCode has a number of plugins that make it even more compelling for Mark Down documents. These include
  • Build in Markdown Preview : Ok, so this isn't really a plugin. Out of the box VSCode supports the previewing of your markdown document as you type. Whilst not really needed, and some people might find this a distraction, it does help you identify any simple mistakes you are making as you put your document together.
  • Markdown PDF : This enables me to export my Mark Down document into a number of formats including pdf, html, png and jpeg with the first two being the most useful. This means that I can work on documents in pdf and export them to HTML to be used in blogs and web pages. The only downside is that it doesn't appear to provide an option to remove the CSS script inside of rhe html file it produces. It's not a bif deal and quick edit makes it simple to use it a multitude of locations.
  • Markdown Shortcuts : This plugin provides key shortcuts for toggling on various aspects of Markdown functionality. I don't often use the shortcuts directly but typically the functionality from the Command Palette (Shift-Command P on Mac). This makes it easier for me to remember some syntax for operations like creating tables.

Create Oracle Database in a Docker Container

九八彩票网址是多少these python (3.6) scripts walk through the creation of a database and standby server. the reason i've done this rather than just take the default configuration is that this approach gives me a lot more control over the build and enables me to change specifc steps. if you are just wanting to get the oracle database running inside of docker i strongly suggest that you use the docker files and guides in the . the approach documented below is very much for someone who is interested in a high level of control over the various steps in the installation and configuration of the oracle database. this current version is build on top of oracle's internal giaas docker image but will be extended to support the public dockers images as well. it aims to build an active data guard model with maximum performance but can be trivially changed to support any of the required models.

it uses a mix of calls to the docker python api and calls direct to the databases via cx_oracle.

九八彩票网址是多少the following code section imports the needed modules to setup up our docker container to create the oracle database. after that we get a docker client handle which enables use to call the api against our local docker environment.

Configuration Parameters

The following section contains the parameters for setting the configuration of the install. The following parameters image_name,host_oradata,sb_host_oradata need to be changed, although sb_host_oradata is only important if you are planning on installing a standby database.

In [3]:
# The following parameters are specific to your install and almost certainly need to be changed
image_name = 'cc75a47617' # Taken from the id value above
host_oradata = '/Users/dgiles/Downloads/dockerdbs/oradataprimary' # The directory on the host where primary database will be persisted
sb_host_oradata = '/Users/dgiles/Downloads/dockerdbs/oradatastby' # The direcotry on the host where the standby database will be persisted
#
# The rest are fairly generic and can be changed if needed
oracle_version = '18.0.0'
db_name = 'ORCL'
stby_name = 'ORCL_STBY'
sys_password =  keyring.get_password('docker','sys') # I'm just using keyring to hide my password but you can set it to a simple sting i.e. 'mypassword'
pdb_name = 'soe'
p_host_name = 'oracleprimary'
sb_host_name = 'oraclestby'
total_memory = 2048

container_oradata = '/u01/app/oracle/oradata'
o_base = '/u01/app/oracle'
r_area = f'{o_base}/oradata/recovery_area'
o_area = f'{o_base}/oradata/'
a_area = f'{o_base}/admin/ORCL/adump'
o_home = f'{o_base}/product/{oracle_version}/dbhome_1'
t_admin = f'{o_base}/oradata/dbconfig'
log_size = 200

Create Primary Database

This code does the heavy lifting. It creates a container oracleprimary (unless you changed the paramter) running the Oracle Database. The containers 1521 port is mapped onto the the hosts 1521 port. This means that to connect from the host, via a tool like sqlplus, all you'd need to do is sqlplus soe/soe@//locahost/soe.

In [4]:
path = f'{o_home}/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'

p_container = client.containers.create(image_name,
                                       command="/bin/bash",
                                       hostname=p_host_name,
                                       tty=True,
                                       stdin_open=True,
                                       auto_remove=False,
                                       name=p_host_name,
                                       shm_size='3G',
                                       # network_mode='host',
                                       ports={1521:1521,5500:5500},
                                       volumes={host_oradata: {'bind': container_oradata, 'mode': 'rw'}},
                                       environment={'PATH':path,'ORACLE_SID': db_name, 'ORACLE_BASE': o_base,'TNS_ADMIN': t_admin}
                                       )

p_container.start()
# Make all of the containers attributes available via Python Docker API
p_container.reload()

The next step uses DBCA and configures features like Automatic Memory Mangement, Oracle Managed Files and sets the size of the SGA and redo logs. It prints out the status of the creation during it's progression. NOTE :九八彩票网址是多少 This step typically takes 10 to 12 minutes.

at this stage you should have a fully functioning oracle database. in theory there's no need to go any further if thats all you want.

Create Stand By Container

This step creates another container to run the standby databases. It should be pretty much instant. NOTE :九八彩票网址是多少 You'll only need to run the rest of the code from here if you need a standby database.

In [8]:
sb_container = client.containers.create(image_name,

Configure the Standby Database

九八彩票网址是多少create some additional directories on the standby so they are consistent with the primary.

Configure the servers for Data Guard

九八彩票网址是多少it might be necessary to pause for a few seconds before moving onto the next step to allow the database to register with the listener...

九八彩票网址是多少the next step is to connect to primary and standby servers and set various parameters and configuration to enable us to run data guard.

first check the status of archive logging on the primary.

Duplicate the Primary database to the Standby database

Standby Database Creation Complete

we now have a primary and standby database that we can begin testing with.

Additional Steps

at this point you should have a physical standby database that is running in maximum performance mode. this might be enough for the testing you want to carry out but there's a number of possible changes that you might want to consider.

  • Change the physical standby database to an Active Standby
  • Convert the current mode (Maximum Performance) to Maximum Protection or Maximum Availability
  • Configure the Oracle Database 19c Active Data Guard feature, DML Redirect

i'll cover these in the following sections but they "icing on the cake" rather than required.

Active Data Guard

this is a relatively trivial change. we just need to alter the standby database to open readonly and then start managed recovery as before

In [29]:

Maximum Performance to Maximum Availability

for this change we'll use the database guard broker command line tool to make the change

In [ ]:
contents = f'''
dgmgrl sys/{sys_password}@{db_name} << EOF
SET ECHO ON;
SHOW CONFIGURATION;
edit database {stby_name} set property logxptmode=SYNC;
edit configuration set protection mode as maxavailability;
SHOW CONFIGURATION;
EOF
'''

create_and_run_script(contents, '/tmp/max_avail.sh', "/bin/bash /tmp/max_avail.sh", p_container)

Maximum Performance to Maximum Protection

九八彩票网址是多少as before we'll use the database guard broker command line tool to make the change.

In [ ]:
contents = f'''
dgmgrl sys/{sys_password}@{db_name} << EOF
SET ECHO ON;
SHOW CONFIGURATION;
edit database {stby_name} set property logxptmode=SYNC;

SHOW CONFIGURATION;
EOF
'''

create_and_run_script(contents, '/tmp/max_prot.sh', "/bin/bash /tmp/max_prot.sh", p_container)

Back to Max Perfromance

九八彩票网址是多少we'll use database guard broker to change us back to asynchronus mode.

In [ ]:
contents = f'''
dgmgrl sys/{sys_password}@{db_name} << EOF
SET ECHO ON;
SHOW CONFIGURATION;
edit configuration set protection mode as maxperformance;

SHOW CONFIGURATION;
EOF
'''

create_and_run_script(contents, '/tmp/max_prot.sh', "/bin/bash /tmp/max_prot.sh", p_container)

Oracle Database 19c Acvtive Data Guard DML Redirect

九八彩票网址是多少on oracle database 19c we can also enable dml redirect from the standby to the primary. i'll add this on the release of the oracle database 19c software for on premises.

Jupyter, Python, Oracle and Docker Part 2

You can find the Python Jupyter Notebook used in this exercise .

云南快乐10分钟遗漏Dominic Giles Blog

九八彩票网址是多少

Build Docker Oracle Database Base Image

the following notebook goes through the process of building an oracle docker image of the oracle database. if you are just wanting to get the oracle database running inside of docker i strongly suggest that you use the docker files and guides in the . the approach documented below is very much for someone who is interested in a high level of control over the various steps in the installation and configuration of the oracle database or simply to understand how the various teps work.

Prerequisites

The process documented below uses a Jupyter Notebook (iPython). The reason I use this approach and not straight python is that it's easy to change and is self documenting. It only takes a few minutes to set up the environment. I've included a requirements file which makes it very simple to install the needed Python libraries. I go through the process of setting up a Jupyter environment for Mac and Linux here.

Running the notebook

Typically the only modification that the user will need to do is to modifythe values in the "Parameters"九八彩票网址是多少 section. The code can then be run by pressing "Command SHIFT" on a Mac or "Ctrl Shift" on Windows. Or by pressing the "Play" icon in the tool bar. It is also possible to run all of the cells automatically, you can do this from "Run" menu item.

In [ ]:
import docker
import os
import tarfile
from prettytable import PrettyTable
from IPython.display import HTML, display, Markdown
import humanize
import re
from ipynb.fs.full.OracleDockerDatabaseFunctions import list_images,list_containers,copy_to,create_and_run_script,containter_exec,copy_string_to_file,containter_root_exec

client = docker.from_env(timeout=600)

Parameters

九八彩票网址是多少this section details the parameters used to define the docker image you'll end up creating. it's almost certainly the case that you'll need to change the parameters in the first section. the parameters in the second section can be changed if there's something i.e. hostname that you want to change

In [ ]:
# You'll need to to change the following two parameters to reflect your environment
host_orabase = '/Users/dgiles/oradata18c' # The directory on the host where you'll stage the persisted datafiles
host_install_dir = '/Users/dgiles/Downloads/oracle18_software' # The directory on the host where the downloaded Oracle Database zip file is.
# You can change any of the following parameters but it's not necssary
p_host_name = 'oracle_db'
oracle_version = '18.0.0'
oracle_base = '/u01/app/oracle'
oracle_home = f'{oracle_base}/product/{oracle_version}/dbhome_1'
db_name = 'ORCL'
oracle_sid= db_name
path=f'{oracle_home}/bin:$PATH'
tns_admin=f'{oracle_base}/oradata/dbconfig'
container_oradata = '/u01/app/oracle/oradata'
r_area = f'{oracle_base}/oradata/recovery_area'
a_area = f'{oracle_base}/admin/ORCL/adump'
container_install_dir = '/u01/install_files'
path = f'{oracle_home}/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'

九八彩票网址是多少attempt to create the needed directories on the host and print warnings if needed

In [42]:
try:
    os.makedirs(host_orabase, exist_ok=True)
    os.makedirs(host_install_dir, exist_ok=True)
except:
   display(Markdown(f'**WARNING** : Unable to create directories {host_orabase} and {host_install_dir}'))
    
files = os.listdir(host_install_dir)
found_similar:bool = False
for file in files:
    if file.startswith('LINUX.X64'):
        found_similar = True
        break
if not found_similar:
    display(Markdown(f"**WARNING** : Are you sure that you've downloaded the needed Oracle executable to the `{host_install_dir}` directory"))

九八彩票网址是多少the first step in creating a usable image is to create a docker file. this details what the docker container will be based on and what needs to be installed. it will use the parameters defined above. it does require network connectivity for this to work as docker will pull down the required images and rpms.

In [43]:
script = f'''
FROM oraclelinux:7-slim

ENV ORACLE_BASE={oracle_base} \
    ORACLE_HOME={oracle_home} \
    ORACLE_SID={oracle_sid} \
    PATH={oracle_home}/bin:$PATH
    
RUN yum -y install unzip
RUN yum -y install oracle-database-preinstall-18c
RUN yum -y install openssl
    
# RUN groupadd -g 500 dba
# RUN useradd -ms /bin/bash -g dba oracle

RUN mkdir -p $ORACLE_BASE
RUN mkdir -p $ORACLE_HOME
RUN mkdir -p {container_install_dir}

RUN chown -R oracle:dba {oracle_base}
RUN chown -R oracle:dba {oracle_home}
RUN chown -R oracle:dba {container_install_dir}

USER oracle
WORKDIR /home/oracle

VOLUME ["$ORACLE_BASE/oradata"]
VOLUME ["{container_install_dir}"]
EXPOSE 1521 8080 5500
'''

with open('Dockerfile','w') as f:
    f.write(script)

and now we can create the image. the period of time for this operation to complete will depend on what docker images have already been downloaded/cached and your network speed.

九八彩票网址是多少once the image has been created we can start a container based on it.

In [45]:
db_container = client.containers.create(image.short_id,
                                       command="/bin/bash",
                                       hostname=p_host_name,
                                       tty=True,
                                       stdin_open=True,
                                       auto_remove=False,
                                       name=p_host_name,
                                       shm_size='3G',
                                       # network_mode='host',
                                       ports={1521:1522,5500:5501},
                                       volumes={host_orabase: {'bind': container_oradata, 'mode': 'rw'}, host_install_dir: {'bind': container_install_dir, 'mode': 'rw'}},
                                       environment={'PATH':path,'ORACLE_SID': db_name, 'ORACLE_BASE': oracle_base,'TNS_ADMIN': tns_admin, 'ORACLE_HOME':oracle_home}
                                       )

#                                        volumes={host_orabase: {'bind': oracle_base, 'mode': 'rw'}, host_install_dir: {'bind': container_install_dir, 'mode': 'rw'}},

db_container.start()
p_ip_adress = db_container.attrs['NetworkSettings']['IPAddress']

九八彩票网址是多少and then created the needed directory structure within it.

In [46]:
containter_exec(db_container, f'mkdir -p {container_oradata}/{db_name}')
containter_exec(db_container, f'mkdir -p {tns_admin}')
containter_exec(db_container, f'mkdir -p {r_area}/{db_name}')
containter_exec(db_container, f'mkdir -p {a_area}')
containter_exec(db_container, f'mkdir -p {oracle_base}/oraInventory')
containter_exec(db_container, f'mkdir -p {oracle_home}')
containter_root_exec(db_container,'usermod -a -G dba oracle')

Unzip Oracle Database software and validate

We now need to unzip the Oracle software which should be located in the host_install_dir variable. This is unzipped within the container not the host. NOTE: I don't stream the output because it's realtively large. It should take 2-5 minutes.

In [47]:
files = [f for f in os.listdir(host_install_dir) if f.endswith('.zip')]
    
if files == 0:
    display(Markdown(f"**There doesn't appear to be any zip files in the {host_install_dir} directory. This should contain the oracle database for Linux 64bit in its orginal zipped format**"))
else:
    display(Markdown(f'Unzipping `{files[0]}`'))
    containter_exec(db_container, f'unzip -o {container_install_dir}/{files[0]} -d {oracle_home}', show_output=False, stream_val=False)
    

Unzipping LINUX.X64_180000_db_home.zip

九八彩票网址是多少and now display the contents of the oracle home

In [48]:
display(Markdown('Directory Contents'))
containter_exec(db_container, f'ls -l {oracle_home}')

the next step is to create an oracle installer response file to reflect the paremeters we've defined. we're only going to perform a software only install.

In [49]:
script = f'''oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v18.0.0
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=dba
INVENTORY_LOCATION={oracle_base}/oraInventory
ORACLE_BASE={oracle_base}
ORACLE_HOME={oracle_home}
oracle.install.db.InstallEdition=EE
oracle.install.db.OSDBA_GROUP=dba
oracle.install.db.OSBACKUPDBA_GROUP=dba
oracle.install.db.OSDGDBA_GROUP=dba
oracle.install.db.OSKMDBA_GROUP=dba
oracle.install.db.OSRACDBA_GROUP=dba
'''

copy_string_to_file(script, f'{oracle_home}/db_install.rsp', db_container)

Run the Oracle Installer

九八彩票网址是多少now we can run the oracle installer in silent mode with a response file we've just created.

In [50]:
containter_exec(db_container, f'{oracle_home}/runInstaller -silent -force -waitforcompletion -responsefile {oracle_home}/db_install.rsp -ignorePrereqFailure')
Launching Oracle Database Setup Wizard...

[WARNING] [INS-32055] The Central Inventory is located in the Oracle base.
   ACTION: Oracle recommends placing this Central Inventory in a location outside the Oracle base directory.
[WARNING] [INS-13013] Target environment does not meet some mandatory requirements.
   CAUSE: Some of the mandatory prerequisites are not met. See logs for details. /tmp/InstallActions2019-03-19_02-40-31PM/installActions2019-03-19_02-40-31PM.log
   ACTION: Identify the list of failed prerequisite checks from the log: /tmp/InstallActions2019-03-19_02-40-31PM/installActions2019-03-19_02-40-31PM.log. Then either from the log file or from installation manual find the appropriate configuration to meet the prerequisites and fix it manually.
The response file for this session can be found at:
 /u01/app/oracle/product/18.0.0/dbhome_1/install/response/db_2019-03-19_02-40-31PM.rsp


You can find the log of this install session at:
 /tmp/InstallActions2019-03-19_02-40-31PM/installActions2019-03-19_02-40-31PM.log

As a root user, execute the following script(s):
1. /u01/app/oracle/oraInventory/orainstRoot.sh
	2. /u01/app/oracle/product/18.0.0/dbhome_1/root.sh

Execute /u01/app/oracle/oraInventory/orainstRoot.sh on the following nodes:
[oracle_db]

Execute /u01/app/oracle/product/18.0.0/dbhome_1/root.sh on the following nodes:

Check /u01/app/oracle/product/18.0.0/dbhome_1/install/root_oracle_db_2019-03-19_14-42-43-621215020.log for the output of root script

Commit the container to create an image

and finally we can commit the container creating an image for future use.

In [52]:
repository_name = 'dominicgiles'
db_container.commit(repository=repository_name,tag=f'db{oracle_version}')
Out[52]:
<Image: 'dominicgiles:db18.0.0'>

Tidy Up

the following code is included to enable you to quickly drop the container and potentially the immage.

db_container.stop()
db_container.remove()

Jupyter, Python, Oracle and Docker Part 1

I'm releasing a few videos and blog entries describing my development and test environments. You can find them below

Part 1



Part 2




The first discusses what Jupyter Notebooks are and the second describes the installation of the environment I use.

There should be two or three more to follow.
