Oracle Apps DBA Cookbook
Volume 1 — A day-to-day operational guide
Practical procedures for Oracle E-Business Suite 12.2 on Oracle Database 19c.
Compiled from field practice on large-scale EBS estates. Every recipe is designed to be readable, adaptable, and safe when used with proper change control.
1. Scope & Target Environment
| Dimension | Assumed Baseline | Notes |
|---|---|---|
| EBS release | 12.2.x (12.2.9 / 12.2.10 / 12.2.11+) | Online patching (ADOP), dual filesystem fs1/fs2 |
| Database | 19c (19.3+), Enterprise Edition | Non-CDB and single-PDB both covered |
| Middle tier | WebLogic Server 10.3.6 / FMW 11g | oacore, forms, oafm, forms-c4ws managed servers |
| OS | IBM AIX 7.x (primary), Oracle Linux 7/8 | AIX-specific recipes flagged [AIX] |
| HA | Data Guard physical standby | Broker-managed, Active Data Guard optional |
| Backup | RMAN with catalog or controlfile-only | Disk + tape (TSM/SBT) variants |
2. Recipe Numbering
Every procedure has a stable ID: R<chapter>.<sequence> — for example R06.23.
IDs are permanent. If a recipe is retired it is marked [RETIRED] rather than renumbered, so cross-references, runbooks, and your own notes never break.
3. Recipe Anatomy
### R02.14 — Short imperative title
Use: One line — when you reach for this.
<script / SQL block>
> Note: gotchas, prerequisites, version differences, destructive warnings.4. Risk Flags
| Flag | Meaning |
|---|---|
[READ] | Read-only. Safe on production at any time. |
[WRITE] | Modifies data or configuration. Take a backup first. |
[OUTAGE] | Requires downtime or causes service interruption. |
[AIX] | AIX-specific syntax or command. |
[ROOT] | Needs root or a privileged OS account. |
Unflagged recipes are [READ] by default.

ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';Section A — Release, Patches & Editions
R02.01 — Confirm EBS release from the database
Use: First question in every ticket, every Oracle SR.
SELECT release_name,
applications_system_name,
last_update_date
FROM fnd_product_groups;This is the authoritative release. Do not trust the login page banner — it can be stale after a patch until caches clear.
R02.02 — List product installation status and patch levels
Use: Determining which products are shared, installed or inactive before applying a family pack.
SELECT fa.application_short_name AS prod,
fat.application_name,
fpi.patch_level,
DECODE(fpi.status,'I','Installed','S','Shared','N','Not installed',fpi.status) AS status,

AND fat.language = USERENV('LANG')
ORDER BY fa.application_short_name;R02.03 — Check whether a specific patch has been applied
Use: Oracle Support asks "is patch 12345678 applied?" — answer in ten seconds.
SELECT bug_number,
creation_date,
last_update_date
FROM ad_bugs
WHERE bug_number = '&patch_number';AD_BUGS records the bug/patch number. A row here means the patch was applied to this edition of the database. For 12.2, always confirm which edition you are connected to — see R02.08.R02.04 — List patches applied in a date range
Use: "What changed last weekend?" during a post-change investigation.
SELECT ap.patch_name,
ap.patch_type,
apr.end_date,

AND TO_DATE('&to_date','DD-MON-YYYY') + 1
ORDER BY apr.end_date DESC;R02.05 — Show full patch run detail for one patch
Use: Confirming a patch completed on every node, not just the one you ran it from.
SELECT ap.patch_name,

FROM ad_adop_sessions
ORDER BY adop_session_id DESC
FETCH FIRST 10 ROWS ONLY;Status codes are
Y (completed), N (not done), X (not applicable), F (failed), R (running). A session with status = 'C' is complete. Anything else at the top of this list means you have an open cycle.R02.07 — List patches applied within an ADOP session
Use: Reconstructing exactly what a patch weekend delivered.

bug_number,
patch_file_name,
node_name,

FROM ad_adop_session_patches
WHERE adop_session_id = &session_id
ORDER BY end_date;R02.08 — Show current run and patch editions
Use: Knowing which edition your session is actually in. Get this wrong and every other query misleads you.
SELECT SYS_CONTEXT('USERENV','CURRENT_EDITION_NAME') AS my_edition,
ad_zd.get_edition('RUN') AS run_edition,
ad_zd.get_edition('PATCH') AS patch_edition
FROM dual;
SELECT edition_name, parent_edition_name, usable
FROM dba_editions
ORDER BY edition_name;PATCH returns null when no patch cycle is open. If my_edition is not the run edition and you did not intend that, disconnect and re-source your environment.R02.09 — Count objects per edition
Use: Judging how much cleanup debt has accumulated across old editions.
SELECT o.edition_name,
o.object_type,
COUNT(*) AS obj_count
FROM dba_objects_ae o
WHERE o.owner = 'APPS'
AND o.edition_name IS NOT NULL
GROUP BY o.edition_name, o.object_type
ORDER BY o.edition_name, obj_count DESC;Old editions accumulate if
cleanup is skipped. A long tail of editions is a strong signal that full cleanup is overdue.R02.10 — List invalid objects by owner and type
Use: Standard post-patch and post-clone check.
SELECT owner, object_type, COUNT(*) AS invalid_count
FROM dba_objects
WHERE status = 'INVALID'
GROUP BY owner, object_type
ORDER BY invalid_count DESC;R02.11 — Generate a targeted recompile script for invalids [WRITE]

TO_CHAR(creation_date,'DD-MON-YYYY') AS registered
FROM fnd_nodes
ORDER BY node_name;Rows for decommissioned hosts, or a stale
AUTHENTICATION node, will break adop. Clean them with FND_CONC_CLONE.SETUP_CLEAN followed by AutoConfig on every tier — never by direct DELETE.R02.13 — Show which services each node supports
Use: Confirming service distribution matches the intended topology.
