  1. How Healthy is your Apps Environment? Easy Health Checks for Apps 11i Lynne Paulus Oracle Applications DBA Fair Isaac

  2. 11i Health Checks: Objectives • Describe ‘Health’ conditions to check in 11i environment • Highlight issues you may want to monitor • Supply SQL statements that do health checks

  3. Fair Isaac and Oracle Apps • Fair Isaac: Decision Support Software - approx 3,000 employees • Bay Area = San Rafael • San Diego, Minnesota and many other locations (Int’l) • Live on Oracle Apps since 1992 • Currently on 11.5.10.2 • Upgraded Nov 2005 from 11.5.8 • Modules = Financials, Projects, HR, OM, many CRM modules • All employees use 11i for Time and Expenses (OTL/iExpense) • Just went live on Project Resource Management

  4. 11i Health Check Characteristics • Overview of your environment’s health at a point-in-time • Not event driven - No alert as soon as condition occurs • Does not replace DB monitoring Software • For critical DB monitoring we use Quest Foglight - notify immediately of critical conditions • Examples: DB down, low disk space

  5. 11i Health Check Characteristics • Use format which is easy to extend • I use simple SQL script run as unix Cron job • Script emails the spool file to DBAs and Sys Admins • Some checks apply to all 11i - some may not apply to your environment • Examples • May be on different version of 11i with different logic • You may not have HR fully implemented so some employee information may not be available

  6. 11i Health Checks: Two Categories • 1) Warnings: You normally expect no rows returned • General, User Security, Profiles, Custom Direct Chgs, Module Specific, Std DB Checks • 2) General Health Checks: (categories overlap with Warnings but general checks often return data) • Invalid Objects • General DB • User Load Checks • Application Users • Profiles • Module Specific

  7. 11i Health Checks: Two Frequencies Frequencies: 1) Daily: Includes both Warnings and General Checks • Will cover these checks in more detail 2) Weekly: • Objects created in last month (DBAs should usually know why objects got created, if not research them) • Count users whose password will expire in next several weeks (look for bubbles of high password expiration)

  8. Section Warning Health Checks

  9. Sample output from Warning Section +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++ Warning Section: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Confirm not in Maintenance Mode - should see no rows no rows selected User Security AND Access Issues section: Show any logins whose password is NOT set to expire in 90 days no rows selected Non-DBAs who have System Administrator or Applic Develop Responsibility no rows selected Terminated employees who still have an active login to Oracle Apps USER_NAME            TERM_DATE                             -------------------- --------------------                             LYNNEPAULUS             06-Jan-06 

  10. Warning Health Checks • Confirm DB not in Maintenance Mode • Profile Option = 'Applications Maintenance Mode‘ • When Profile set to ‘NORMAL’ means not in Maint Mode so application should function normally • If start Forms and Apache while in Maint Mode, users have access problems but startup looks successful • We added this Profile check to our Application Start shell script • We get a warning and application does not start • Makes obvious dbas forgot to turn Maint Mode off

  11. Warning Health Checks • User Warnings • Users lacking password expiration setup • For automating new employee login accounts see Jordan Kraft’s paper OAUG June 2005 • Non-DBAs/Sys Admins who have System Administrator responsibility USER_NAME END_DATE TODAY RESPONSIBILITY --------- -------- --------- ------------------------ JASONBURGOS 14-JAN-06 System Administrator • Terminated employees with active FND login account USER_NAME TERM_DATE -------------------- --------- LYNNEPAULUS 06-Jan-06

  12. Warning Health Checks • Profile Warnings • Confirm Examine function is password protected • Profile = ‘Utilities:Diagnostics’ • When ‘Y’ then allows Help->Diagnostics->Examine without requiring Apps password – Also protects other Help->Diagnostics actions • Cryptic Logic so helpful to explain logic of setting in SQL script

  13. Warning Health Checks • Custom Direct Changes Warnings • Standard objects you customized (not ‘extensions’) • Keep to absolute minimum - avoid like plague • Lose your changes when Oracle patches or upgrades object • Health Check to see whether object changed recently – Alerts you that you may have lost your change • Examples • Views customized for better performance or logic (e.g. ADP Views) • Package Changes: iExpense Approval - emergency customization to allow CEO to enter Expense Report Owner Object Name Created Last DDL ---- -------------------- --------- --------- APPS AP_WEB_DB_HR_INT_PKG 08-OCT-99 13-JAN-06

  14. Warning Health Checks • Module Specific Warnings • Receivables (AR) • Orphaned rows in ar_journal_interim_all table • Caused by AR ‘Journal Entries Report' ending in Error • Check with Support on how to correct • Projects (PA) • Orphaned rows in pa_unbilled_rec_reporting table • Caused by 'MGT: Unbilled Receivables Aging' ending in Error • Check with Support on how to correct

  15. Warning Health Checks • General DB Warnings • Locked db user accounts • We have setup some DB accounts to ‘lock’ after 3 invalid password tries • We only have invalid password logic on custom schemas • Expansion in Undo Tablespace • Can go unnoticed and take a lot more disk space (ours grew from 3 GB to 11 GB during upgrade) Tablespace Total MB Used MB Avail MB Percent Free ------------ --------- --------- --------- ----------- APPS_UNDOTS1 3,518.00 389.19 3,128.81 88.94

  16. Sample output from Warning Section ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++ Warning Section: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Confirm not in Maintenance Mode - should see no rows no rows selected User Security AND Access Issues section: Show any logins whose password is NOT set to expire in 90 days no rows selected Non-DBAs who have System Administrator or Applic Develop Responsibility no rows selected Terminated employees who still have an active login to Oracle Apps USER_NAME            TERM_DATE                             -------------------- --------------------                             LYNNEPAULUS             06-Jan-06           

  17. Section General Health Checks

  18. General Health Checks • General Health Checks - normally expect to return rows • Invalid Objects: • Apps (we currently have 4 that are always invalid) • We do not expect more than our ‘normal’ invalids (compile apps) • Custom Schema (we normally have zero invalids) OWNER OBJECT_NAME OBJECT_TYPE CREATED -------- ------------------------------ ------------ --------- APPS MRP_AN_ONHAND_SUPPLIES_V VIEW 23-AUG-01 APPS MRP_AP_ONHAND_SUPPLIES_V VIEW 23-AUG-01 APPS MRP_AP_OPERATION_RESOURCES_V VIEW 23-AUG-01 APPS MRP_SN_OPR_RESS_T2 TRIGGER 23-AUG-01

  19. General Health Checks • General RDBMS Checks • Show count of failed DB logins (this does not include failed 11i logins) • Popular with auditors • List expired Schema accounts USERNAME CREATED DEFAULT TS TEMP STATUS LOCK_DATE -------------- --------- ---------- ---- ------ -------------- AD_MONITOR 12-NOV-05 TOOLS TEMP EXPIRE 11/12/05 12:34

  24. General Health Checks • Module Specific Checks • Vary widely from site to site • General Ledger: GL consolidation tables that may be orphaned • iProcurement: Check for stuck Web requisitions • Research ‘Purge System Saved Requisition’ Con Program • OM: Check OE Processing Msgs for Number AND types of rows • Research ‘Message Purge’ Concurrent Program to clean

  25. Section Health Check Tips

  26. 11i Health Check Tips: • How much time needed to monitor Health Check Report? • Warning section first - Expect no rows so scan is quick • General Section - Scan for differences • Use easy to maintain format - Keep it Simple • My unix shell script emails SQL spool file to Apps DBAs • Independent of monitoring Software • Easy to expand • I add additional checks at least once a month – takes about 5 minutes to expand • Any time new condition ‘bites’ us, I add to health check

  27. 11i Health Check Tips: • Good place to store logic behind certain issues • Captures SQL logic used to find data and reason why we care • Acts as repository of Apps exception conditions – better than using own memory to remember details of issues • Use as Reference as to where certain data stored • Add comments about when a check will change (e.g. after migrate to 11.5.10, this condition can be resolved by Con Pgm) • Consider including ‘as time allows’ reminders • We have more tasks than can get to so include queries that remind of outstanding issues (e.g. GL Consolidation tables)

  28. 11i Health Check Tips: • Treat Health Check script as important source code • Archive off current version before making any changes • Add Change Log entry at top of script for audit trail • We do not include in our Change Control process since script modifies no data • Better to error on side of having too many checks than too few • Put less important queries near end of script • Must change my health check script to work at your site • Your health check driver logic will probably vary from mine • My driver is unix shell script - runs from Unix Cron • Could use Oracle Alerts, 3rd party software, etc

  29. Conclusion: • My health check SQL script available on NorCal OAUG Web site: http://www.norcaloaug.org/2006_training_day/TDpresentations.htm • Filename = ck_apps_health.sql • Many Apps Health Checks can be done automatically • If you don’t implement automated Health Checks • Modify my SQL script for your site and run manually • Review output - look for changes in 11i you want to make • For Example - Password Protect ‘Examine’ feature

  30. Off-Topic Comments: • We found 11.5.10.2 pretty stable for application modules • We’ve had lots of issues with Users, Responsibility Assignments and Workflow Role tables? Redesign of this logic was extensive so it seems ‘bleeding edge’ • Re-assign Fnd User to employee – caused all user’s responsibility assignments to be duplicated and corrupted • Be very cautious of direct updates to fnd_user table • Lots of Lock contention - Eventually crashed DB after killing lock holder

  31. Q and A: • General Questions: • Who is using DataGuard with 11i? • How do you monitor who is currently logged into Forms and Self-Service? • Do you have your users time-out when inactive? • How quickly? • How do you get semi-exclusive access to 11i? • How often do you do routine maintenance of Concurrent Manager Tables? • What other 11i health checks do you run? • Who has implemented Project Resource Management?
