Oracle EBS 12.2 – Patch File System Validation Checklist

1. Take Backup of Critical Files

Take backup of the following files from all RUN/PATCH nodes and keep them in a shared NAS mount location for easy recovery.

a) Context Files

Backup all context XML files.

Example:

$INST_TOP/appl/admin/*.xml

b) Environment Files

$APPL_TOP/*.env

c) WebLogic Domain Configuration

$FMW_HOME/user_projects/domains/EBS_domain_<SID>/config/config.xml

---

2. Copy Patch to Shared Mount Point

Copy the required patch files to the extranet/shared mount location.

Example:

/nas/ebs_patches/

---

3. Run ADOP Validation

Execute validation before starting the patching cycle.

adop phase=validate

Ensure validation completes successfully without errors.

---

4. Validate Admin Server and Node Manager

Connect to PATCH file system and validate startup/shutdown of:

• Admin Server (Primary Node)
• Node Manager (All Nodes)

---

Source Patch Environment

cd ~

. ./EBSapps.env patch

---

Admin Server Start/Stop Validation

$ADMIN_SCRIPTS_HOME/adadminsrvctl.sh start
$ADMIN_SCRIPTS_HOME/adadminsrvctl.sh stop

---

Node Manager Start/Stop Validation

$ADMIN_SCRIPTS_HOME/adnodemgrctl.sh start
$ADMIN_SCRIPTS_HOME/adnodemgrctl.sh stop

---

5. Ensure No Patch File System Processes Are Running

Verify no residual PATCH filesystem processes are active across application nodes.

Example:

ps -ef | grep fs2

If any unwanted processes exist, stop them cleanly before proceeding.

---

6. Validate Node Manager Port Configuration

Ensure:

• RUN filesystem ports are identical across all RUN nodes.
• PATCH filesystem uses a different Node Manager port.

---

Verify Node Manager Listen Port

grep -i listen-port \
$FMW_HOME/user_projects/domains/EBS_domain_<SID>/config/config.xml

---

Extract Port Number

grep -i listen-port \
$FMW_HOME/user_projects/domains/EBS_domain_<SID>/config/config.xml \
| sed -n 1p \
| cut -d'>' -f2 \
| cut -d'<' -f1

---

Recommended DBA Validation Checks

Verify Node Manager Process

ps -ef | grep NodeManager

---

Check Listening Ports

netstat -an | grep LISTEN | grep <PORT>

---

Verify WebLogic Admin Connectivity

curl -I http://hostname:port

---

Important Best Practices

• Always validate PATCH filesystem before adop prepare.
• Ensure no orphan Java/WLS processes exist.
• Maintain backup of config.xml before changes.
• Validate SSH equivalency between nodes.
• Confirm shared filesystem mount availability on all nodes.
• Check free space in:
  • $PATCH_TOP
  • $NE_BASE
  • $COMMON_TOP

---

Typical Real-Time Use Cases

This checklist is commonly used before:

• adop phase=prepare
• adop fs_clone
• WebLogic recovery
• Node Manager troubleshooting
• Dual filesystem synchronization issues
• Patch filesystem corruption validation
