EBS Live Status — How Each Card Is Sourced

Each service card in the Monitor tab probes a different signal source. Understanding the source tells you what a status means — and what it cannot tell you.

DB only — Oracle metadata query; valid even when app tier is down
TCP probe — TCP port reachability to the EBS host
DB + TCP — DB metadata cross-checked with TCP probe (composite signal)
Shell (Phase 3) — Requires SSH execution; not yet implemented
Card Source What it detects Phase 3 upgrade path
OPMN
Legacy Oracle AS / Forms 10g/11g process manager. Not present on EBS 12.2+ WebLogic stacks — shows N/A if port 6200 is closed.
 TCP probe TCP reachability on port 6200. Absent on 12.2+ = not_applicable, not DOWN. No upgrade planned — opmnctl status is only relevant on legacy stacks.
NodeManager
WebLogic 12c Node Manager daemon. Distinct from OPMN — different port (5556), different binary, different lifecycle.
 TCP probe TCP reachability on port 5556. UP = NM is accepting connections. Phase 3: parse nodemanager.log last heartbeat timestamp via SSH.
WebLogic Admin Server
WLS Admin Server hosts the WebLogic console and coordinates managed servers. We do not shell out to adadminsrvctl.sh — it requires APPS + WLS passwords which we have no vault for yet.
 DB + TCP DB: fnd_oam_managed_types target_status. TCP: probe admin port (default 7001 or s_wls_adminport profile). Composite: both UP = running; either down = DOWN. Phase 3: adadminsrvctl.sh status once secrets vault ships for APPS+WLS password storage.
Apps Listener
Oracle TNS Listener for EBS application tier. Port read from fnd_oam_metval.APPS_JDBC_URL.
 DB only Listener port presence in APPS metadata. Does not TCP-probe the listener directly. Phase 3: TCP probe on the extracted port to confirm listener is actually accepting connections.
Apache (OHS)
Oracle HTTP Server — the web front-end for EBS self-service pages.
 DB only fnd_svc_components component_status for HTTP-type component. Phase 3: adapcctl.sh status via SSH.
OACore
OA Framework managed server — required for all OAF-based self-service pages.
 DB only fnd_svc_components component_status for oacore-type component. Phase 3: admanagedsrvctl.sh status oacore_server1 via SSH.
Forms
Oracle Forms managed server — required for all Forms-based EBS screens.
 DB only fnd_svc_components component_status for forms-type component. Phase 3: admanagedsrvctl.sh status forms_server1 via SSH.
OAFM
OA Framework Mobile managed server.
 DB only fnd_svc_components component_status for oafm-type component. Phase 3: admanagedsrvctl.sh status oafm_server1 via SSH.
Concurrent Managers
Internal Concurrent Manager (FNDICM) + running/target process counts. Background job processing for EBS.
 DB only fnd_concurrent_queues_vl running_processes, target_processes. Pending + 24h error counts from fnd_concurrent_requests. N/A — CM status is authoritative in the DB.
Workflow Mailer EBS only
WF Notification Mailer — only shown on EBS-detected connections. DB-resident service; valid even when app tier is down.
 DB only fnd_svc_components for WF_MAILER% type. Stuck/error counts from wf_notifications and wf_error. N/A — WF Mailer status is authoritative in the DB.
OPP EBS only
Output Post Processor — only shown on EBS-detected connections. Handles concurrent request output delivery.
 DB only fnd_svc_components for Output Post Processor. Queue depth from fnd_concurrent_requests FNDCPOPP. N/A — OPP status is authoritative in the DB.

Frequently Asked Questions

Why does OPMN show N/A on my EBS 12.2 instance?
OPMN (opmnctl) is the Oracle AS process manager used in EBS 11i and 12.0/12.1 app tiers. EBS 12.2 moved to a WebLogic 12c application tier — OPMN is not installed. If port 6200 is not reachable, TuneVault reports not_applicable rather than DOWN, since absence is expected on 12.2+ stacks.
Why doesn't TuneVault run adadminsrvctl.sh status for WebLogic Admin Server?
adadminsrvctl.sh status requires both the APPS schema password and the WebLogic admin password passed as arguments. TuneVault does not store those credentials — and shipping password-in-argument SSH calls without a secrets vault is a security regression we've explicitly blocked. Until Phase 3 ships with proper secrets management, the WLS Admin card uses a composite DB metadata + TCP probe instead. The card tooltip says exactly this.
What does "DB only" mean for Apache / managed servers?
TuneVault reads fnd_svc_components for the component's registered status in the Oracle DB. This is usually accurate — EBS updates this table when services start/stop through the admin console. However, it cannot detect cases where the process crashed without updating the DB record. Phase 3 SSH commands will give a ground-truth shell-level status.
Why are Workflow Mailer and OPP only shown on EBS connections?
These services only exist in Oracle E-Business Suite — they're meaningless on a plain Oracle DB connection. When TuneVault detects no EBS tier (via the APPS.DUAL probe during health check), these cards are hidden entirely to avoid confusion.
What is Phase 3?
Phase 3 is the planned SSH execution layer. Commands will be routed through the TuneVault proxy agent already installed on your EBS server, with a secrets vault for storing APPS/WLS passwords encrypted. Phase 3 upgrades several "DB only" cards to shell-verified status checks. The Control tab already shows the Phase 3 command whitelist in dry-run mode.
