Download s/w: 2Gb in size so will take some time depending on download speed, took me 15 minutes
If you don’t already have an account you will need to create one to download the s/w:
Will get prompted to allow app to make changes to PC, accept this.
Click Next >:
Read Agreement and select ‘I accept the terms in the license agreement’ if you agree
Then : click Next >:
Choose location to install the s/w, it will default to C: drive and window account in path
I will change to D: as I have more space there on my PC, also update the account path to be ‘oracle’
So: C:\app\oracle\product\18.0.0\ OR D:\app\oracle\product\18.0.0
Click Next >:
Enter Password to be used for system accounts, as this is just a test install I will choose ‘oracle123’ for this, you can change afterwards if you need: (alter user <username> identified by <password>;)
Click Next >:
Review Summary Screen and click Install:
During the install, Windows defender will alert for java firewall rule, I’ve changed this to
‘Private networks, such as my home or work network’,
I suspect other Virus/Security s/w may also need to have options changed or alert as well.
This will take 30 Minutes
Once install is complete we are presented with final screen:
Note the details for our XE DB:
Pluggable DB: XEPDB1
Enterprise Express: https://localhost:5500/em
The container DB will be called XE.
Click Finish, to close installer
Check DB in GUI Enterprise Manager Express
User Name: sys
Container name: <Leave blank>
as sysdba: tick box
Optional Install SQL Developer
Download SQL Developer so we have a nice front end GUI to do development work using Oracle XE 18c: 400M, 3 mins to download
Right click ‘sqldeveloper.exe’ -> create short cut
Then copy/move new shortcut to desktop for easy access.
If prompted you can copy preferences from a previous version of sqldeveloper
Click new connection:
Save Password: check box
Service name: xepdb1
Then click test, should see : Status Success
Click Save -> Click Connect
You are now connected to 18c XE db.
Can optionally update tnsnames.ora file in <s/w base dir>/network/admin/tnsnames.ora file to add an connection alias for xepdb1 as below, for me that directory is : D:\app\oracle\product\18.0.0\dbhomeXE\network\admin
(ADDRESS = (PROTOCOL = TCP)(HOST = ACER-HOME-PC)(PORT = 1521))
(SERVER = DEDICATED)
(SERVICE_NAME = XEPDB1)
Optional, Uninstall Oracle 18c XE and delete database (destructive) – CAUTION
(Will need a reboot at the end to complete, but can reboot later if needed)
As per documentation: https://docs.oracle.com/en/database/oracle/oracle-database/18/xeinw/deinstalling-oracle-database-xe.html#GUID-DC36940C-D201-457B-A3D5-D6E2BB800120
Use Add or Remove Programs to deinstall Oracle Database XE:
In the Windows Control Panel, select Add or Remove Programs.
Select Oracle Database 18c Express Edition.
Click Change/Remove or Uninstall.
Follow the prompts to deinstall Oracle Database Express Edition. After few minutes, the window will close and the deinstallation will be complete.
Right Click Oracle Database 18c Express Edition -> Uninstall
Take 30 minutes.
Once PC has rebooted uninstall is complete.
Uninstall still leaves behind services: (If you don’t run cmd/dos prompt as administrator you will not be able to delete the service)
Run cmd as administrator , cmd -> right click run as adminstrator
sc delete OracleJobSchedulerXE
sc delete OracleOraDB18Home1TNSListener
sc delete OracleServiceXE
sc delete OracleVssWriterXE
sc delete OracleOraDB18Home1MTSRecoveryService
Clean up folders left behind, for me it was, check beforehand contents of folder to be sure, before deleting, should just got to recyclebin anyway, if you needed to recover.
