Assume:
- OS: RHEL 7 (64-bit)
- You already have:
jdk-17*.rpmsqldeveloper-*.rpm
- You have root access
🔹 PART 1: Install JDK 17 (RPM)
1️⃣ Switch to root
su - root
2️⃣ Verify the RPM file
ls -lh jdk-17*.rpm
(Optional check)
rpm -qip jdk-17*.rpm
3️⃣ Install JDK 17
rpm -ivh jdk-17*.rpm
If already installed and you want to upgrade:
rpm -Uvh jdk-17*.rpm
4️⃣ Verify JDK Installation
java -version
Expected output:
java version "17.x.x"
Java(TM) SE Runtime Environment
5️⃣ Find JDK Installation Path
alternatives --display java
Typical path:
/usr/lib/jvm/jdk-17
Confirm:
ls /usr/lib/jvm
6️⃣ Set JAVA_HOME (System Wide – Recommended)
Edit:
vi /etc/profile.d/java.sh
Add:
export JAVA_HOME=/usr/lib/jvm/jdk-17
export PATH=$JAVA_HOME/bin:$PATH
Apply:
source /etc/profile.d/java.sh
Verify:
echo $JAVA_HOME
java -version
🔹 PART 2: Install Oracle SQL Developer (RPM)
SQL Developer does NOT need Oracle DB installed
It only needs Java
1️⃣ Install SQL Developer RPM
rpm -ivh sqldeveloper-*.rpm
This installs SQL Developer under:
/opt/sqldeveloper
Verify:
ls /opt/sqldeveloper
2️⃣ Configure SQL Developer to Use JDK 17
Edit:
vi /opt/sqldeveloper/sqldeveloper/bin/sqldeveloper.conf
Add or modify:
SetJavaHome /usr/lib/jvm/jdk-17
⚠️ This step is mandatory, otherwise SQL Developer will not start.
3️⃣ Verify SQL Developer Installation
Run:
/opt/sqldeveloper/sqldeveloper.sh
Or from anywhere:
sqldeveloper
(If command not found, add alias)
4️⃣ Create Desktop Shortcut (Optional – GUI Systems)
ln -s /opt/sqldeveloper/sqldeveloper.sh /usr/local/bin/sqldeveloper
🔹 PART 3: Validate Everything
Java
java -version
SQL Developer
sqldeveloper
You should see Oracle SQL Developer GUI 🎉
🔹 COMMON ISSUES & FIXES
❌ SQL Developer doesn’t start
✔️ Check Java path:
which java
✔️ Confirm config:
cat /opt/sqldeveloper/sqldeveloper/bin/sqldeveloper.conf
❌ Error: Unsupported Java Version
Ensure JDK 17, not JRE:
rpm -qa | grep jdk
❌ DISPLAY Error (Remote Server)
export DISPLAY=:0
Or use X11 forwarding:
ssh -X user@server
🔹 BEST PRACTICE (DBA / Server)
| Component | Recommendation |
|---|---|
| JDK | System-wide (/usr/lib/jvm) |
| SQL Developer | /opt/sqldeveloper |
| GUI usage | Use X11 or install on local machine |
