SQL*Plus command line history completion

 

The rlwrap (readline wrapper) utility provides a command history and editing of keyboard input

for any other command. This is a really handy addition to SQL*Plus and RMAN .

Download the latest rlwrap software from the following URL.
http://utopia.knoware.nl/~hlub/uck/rlwrap/

Unzip and install the software using the following commands.

gunzip rlwrap*.gztar -xvf rlwrap*.tarcd rlwrap*./configuremakemake checkmake install

Run the following commands, or better still append then to the “.bash_profile” of the

oracle software owner.

alias sqlplus=’rlwrap ${ORACLE_HOME}/bin/sqlplus’
alias rman='rlwrap ${ORACLE_HOME}/bin/rman'
alias expdp='rlwrap ${ORACLE_HOME}/bin/expdp'

You can now start SQL*Plus or RMAN using “sqlplus” and “rman” respectively, and you will have

a basic command history and the current line will be editable using the arrow and delete keys.

Analyze your Oracle Statspack Report

 

StatspackAnalyzer is a true expert system that seeks to codify expert DBA knowledge and advice against any

STATSPACK or AWR report. The well-structured decision rules of expert Oracle tuning specialists were collected,

quantified and then generalized and validated against real-world STATSPACK and AWR reports.

While no automated tool can fully replicate the decision processes of a human DBA tuning expert, this tool

makes observations about exceptional conditions within the STATSPACK or AWR report. This tool was never

intended to replace the human intuition of an Oracle performance expert, and all observations from

statspackanalyzer should be validated with a human expert.

 

Script to Monitor Concurrent Jobs and Hanging Sessions

 

Here is a monitoring system to monitor all concurrent jobs, concurrent managers and hung sessions every

hour proactively and take appropriate action immediately. It gives the following reports

1. List of Concurrent Jobs that completed with error in last one hour.
2. List of Concurrent Jobs running for more then 1 hour.
3. List of concurrent Jobs completed with Warning in last one hour
4. List of Jobs that are Pending Normal for more than 10 Minutes.
5. List of Hung sessions or Orphan sessions.
6. List of Concurrent managers with Pending Normal jobs.
7. Critical Jobs completed in last one hour with completion time.

Prevent Concurrent Requests Executing on New Cloned Environment

 

To prevent concurrent requests executing on a newly cloned environment 2 steps will be required. 1) Prevent Concurrent Managers from starting as part of the Clone 2) Change data concerning concurrent requests so they do not execute when the concurrent managers start. To prevent Applications Services (including Concurrent Managers) from starting automatically during Rapid Clone an enhancement request has been raised to see if this can be considered an option during the clone. Until this feature is available there is the following workaround. 1. Edit the $COMMON_TOP/clone/bin/adcfgclone.pl 2. Go to the end of the file 3. Change the following lines:- print “\n Starting application Services for $s_dbSid:\n”; print “Running:\n”; print(” $s_com/admin/scripts/$s_contextname/adstrtal.$ext $s_apps_user/<appspwd>\n”); system(“$s_com/admin/scripts/$s_contextname/adstrtal.$ext $s_apps_user/$PWD”); TO: print “\nNOT Starting application Services for $s_dbSid:\n”; #print “Running:\n”; #print(” $s_com/admin/scripts/$s_contextname/adstrtal.$ext $s_apps_user/<appspwd>\n”); #system(“$s_com/admin/scripts/$s_contextname/adstrtal.$ext $s_apps_user/$PWD”); 4. Run “perl adcfgclone.pl appsTier” as normal. The services will not start Automatically when the clone completes allowing data to be changed safely. There is a need to change 2 sets of concurrent requests to prevent execution a) Terminate ‘Running’ Requests b) Set Pending jobs to ‘On Hold’ a) Set Terminating or Running to Completed/Terminated UPDATE fnd_concurrent_requests SET phase_code = ‘C’, status_code = ‘X’ WHERE status_code =’T’ OR phase_code = ‘R’ / b) Place Pending/(Normal/Standby) to On Hold UPDATE fnd_concurrent_requests SET hold_flag = ‘Y’ WHERE phase_code = ‘P’ AND status_code in (‘Q’,'I’) / Once these changes have been committed then the Application services including concurrent manager can be restarted and the concurrent jobs will not be executed.

Queries Related to Concurrent Requests in 11i Applications

As part of day to day work, we need to use lot of queries to check the information about concurrent requests. Here are few queries which can be frequently used for day to day works and troubleshooting concurrent request / manager issues. Note: These queries needs to be run from APPS schema. Scheduled concurrent requests Lot of times we need to find out the concurrent programs scheduled. Users can schedule the concurrent requests in three ways (To run once at a specified time / To run periodically / To run on specific days of the month or week). The below query will return all the concurrent requests which are scheduled using any of the above methods: SELECT cr.request_id, DECODE (cp.user_concurrent_program_name, 'Report Set', 'Report Set:' || cr.description, cp.user_concurrent_program_name ) NAME, argument_text, cr.resubmit_interval, NVL2 (cr.resubmit_interval, 'PERIODICALLY', NVL2 (cr.release_class_id, 'ON SPECIFIC DAYS', 'ONCE') ) schedule_type, DECODE (NVL2 (cr.resubmit_interval, 'PERIODICALLY', NVL2 (cr.release_class_id, 'ON SPECIFIC DAYS', 'ONCE') ), 'PERIODICALLY', 'EVERY ' || cr.resubmit_interval || ' ' || cr.resubmit_interval_unit_code || ' FROM ' || cr.resubmit_interval_type_code || ' OF PREV RUN', 'ONCE', 'AT :' || TO_CHAR (cr.requested_start_date, 'DD-MON-RR HH24:MI'), 'EVERY: ' || fcr.class_info ) schedule, fu.user_name, requested_start_date FROM apps.fnd_concurrent_programs_tl cp, apps.fnd_concurrent_requests cr, apps.fnd_user fu, apps.fnd_conc_release_classes fcr WHERE cp.application_id = cr.program_application_id AND cp.concurrent_program_id = cr.concurrent_program_id AND cr.requested_by = fu.user_id AND cr.phase_code = 'P' AND cr.requested_start_date > SYSDATE AND cp.LANGUAGE = 'US' AND fcr.release_class_id(+) = cr.release_class_id AND fcr.application_id(+) = cr.release_class_app_id;   Note: The “SCHEDULE” column in the above query returns a string of zeros and ones for the requests which are scheduled on specific days of the month or week. Positions 1 through 31: Specific day of the month. Position 32: Last day of the month Positions 33 through 39: Sunday through Saturday Checking the duplicated schedules of the same program with the same arguments The below query can be used to check the duplicated schedule of the same program with the same arguments. This can be used to alert the users to cancel these duplicated schedules. Note: This query will return even though the request was submitted using a different responsibility. SELECT request_id, NAME, argument_text, user_name FROM (SELECT cr.request_id, DECODE (cp.user_concurrent_program_name, 'Report Set', 'Report Set:' || cr.description, cp.user_concurrent_program_name ) NAME, argument_text, fu.user_name FROM apps.fnd_concurrent_programs_tl cp, apps.fnd_concurrent_requests cr, apps.fnd_user fu WHERE cp.application_id = cr.program_application_id AND cp.concurrent_program_id = cr.concurrent_program_id AND cr.requested_by = fu.user_id AND cr.phase_code = 'P' AND cr.requested_start_date > SYSDATE AND cp.LANGUAGE = 'US' AND fu.user_name NOT LIKE 'PPG%') t1 WHERE EXISTS ( SELECT 1 FROM (SELECT cr.request_id, DECODE (cp.user_concurrent_program_name, 'Report Set', 'Report Set:' || cr.description, cp.user_concurrent_program_name ) NAME, argument_text, fu.user_name FROM apps.fnd_concurrent_programs_tl cp, apps.fnd_concurrent_requests cr, apps.fnd_user fu WHERE cp.application_id = cr.program_application_id AND cp.concurrent_program_id = cr.concurrent_program_id AND cr.requested_by = fu.user_id AND cr.phase_code = 'P' AND cr.requested_start_date > SYSDATE AND cp.LANGUAGE = 'US' AND fu.user_name NOT LIKE 'PPG%') t2 WHERE t1.NAME = t2.NAME AND t1.argument_text = t2.argument_text AND t1.user_name = t2.user_name GROUP BY NAME, argument_text, user_name HAVING COUNT (*) > 1) ORDER BY user_name, NAME  Average pending time per request This is a very useful query to check the performance of the concurrent managers. Average pending time for a request is calculated like below: (“Highest of Requested_start_date or Date_submitted” – Actual_start_date ) / Total requests A Request can be in Pending state for variety of reasons like conflict with other requests, improperly tuned managers (sleep seconds / cache size / number of managers etc) We can schedule this script to gather data regularly for historical analysis as we normally purge the concurrent requests regularly. SELECT TO_CHAR (actual_start_date, 'DD-MON-YYYY') DAY, concurrent_queue_name, (SUM ( ( actual_start_date - (CASE WHEN requested_start_date > request_date THEN requested_start_date ELSE request_date END ) ) * 24 * 60 * 60 ) ) / COUNT (*) "Wait_Time_per_Req_in_Secs" FROM apps.fnd_concurrent_requests cr, apps.fnd_concurrent_processes fcp, apps.fnd_concurrent_queues fcq WHERE cr.phase_code = 'C' AND cr.actual_start_date IS NOT NULL AND cr.requested_start_date IS NOT NULL AND cr.controlling_manager = fcp.concurrent_process_id AND fcp.queue_application_id = fcq.application_id AND fcp.concurrent_queue_id = fcq.concurrent_queue_id GROUP BY TO_CHAR (actual_start_date, 'DD-MON-YYYY'), concurrent_queue_name ORDER BY 2 Note: Depending on the purging schedules some requests might miss if the corresponding data in fnd_concurrent_processes is purged. Checking which manager is going to execute a program The below query identifies the manager which will be executing a given program. This query is based on the specialization rules set for the managers. SELECT user_concurrent_program_name, user_concurrent_queue_name FROM apps.fnd_concurrent_programs_tl cp, apps.fnd_concurrent_queue_content cqc, apps.fnd_concurrent_queues_tl cq WHERE cqc.type_application_id(+) = cp.application_id AND cqc.type_id(+) = cp.concurrent_program_id AND cqc.type_code(+) = 'P' AND cqc.include_flag(+) = 'I' AND cp.LANGUAGE = 'US' AND cp.user_concurrent_program_name = '&USER_CONCURRENT_PROGRAM_NAME' AND NVL (cqc.concurrent_queue_id, 0) = cq.concurrent_queue_id AND NVL (cqc.queue_application_id, 0) = cq.application_id AND cq.LANGUAGE = 'US' To see all the pending / Running requests per each manager wise SELECT request_id, phase_code, status_code, user_name, user_concurrent_queue_name FROM apps.fnd_concurrent_worker_requests cwr, apps.fnd_concurrent_queues_tl cq, apps.fnd_user fu WHERE (cwr.phase_code = 'P' OR cwr.phase_code = 'R') AND cwr.hold_flag != 'Y' AND cwr.requested_start_date <= SYSDATE AND cwr.concurrent_queue_id = cq.concurrent_queue_id AND cwr.queue_application_id = cq.application_id AND cq.LANGUAGE = 'US' AND cwr.requested_by = fu.user_id ORDER BY 5 Note: The same information can be seen in Administer Concurrent Manager form for each manager. Checking the incompatibilities between the programs The below query can be used to find all incompatibilities in an application instance. SELECT a2.application_name, a1.user_concurrent_program_name, DECODE (running_type, 'P', 'Program', 'S', 'Request set', 'UNKNOWN' ) "Type", b2.application_name "Incompatible App", b1.user_concurrent_program_name "Incompatible_Prog", DECODE (to_run_type, 'P', 'Program', 'S', 'Request set', 'UNKNOWN' ) incompatible_type FROM apps.fnd_concurrent_program_serial cps, apps.fnd_concurrent_programs_tl a1, apps.fnd_concurrent_programs_tl b1, apps.fnd_application_tl a2, apps.fnd_application_tl b2 WHERE a1.application_id = cps.running_application_id AND a1.concurrent_program_id = cps.running_concurrent_program_id AND a2.application_id = cps.running_application_id AND b1.application_id = cps.to_run_application_id AND b1.concurrent_program_id = cps.to_run_concurrent_program_id AND b2.application_id = cps.to_run_application_id AND a1.language = 'US' AND a2.language = 'US' AND b1.language = 'US' AND b2.language = 'US' The table apps.fnd_concurrent_program_serial has the information about incompatibilities.

Create a User Event Trace in 11i / R12

A user event trace is very handy for tracing sql operations to debug various issues. The benefit of a user event trace is that it is linked to a specific user so that only code run by this user is traced. This makes diagnosis easier when compared to similar tracing methods at the database level where all user calls are traced. Step 1 Login to Oracle Applications and select the System Administrator responsibility. Choose Profile – System Step 2 In the find profile field select the user which you wish to trace. In the profile field enter ‘Initialization SQL Statement – Custom” Select find Step 3 In the find profile results form copy and paste the following into the ‘user’ field. Do not update the site level field. begin fnd_ctl.fnd_sess_ctl(”,”,’TRUE’,'TRUE’,'LOG’,'ALTER SESSION SET EVENTS=’||””||’10046 TRACE NAME CONTEXT FOREVER, LEVEL 12′||””);end; Note: copy and paste the above as one line. Failure to paste the values properly or pasting the values with incorrect syntax will result in this user not being able to login   Step 4 Save the profile option change. Stop and start the java virtual machine for the change to take effect 11i: use adapcctl.sh r12: use adoacorectl.sh Step 5 Login to the application and reproduce the issue. Then quickly log off. Try and avoid any un-necessary keystrokes as this simply makes the log files larger and the issue hard to pinpoint in the logs. Step 6 login to unix/windows as the oracle user. Navigate to the user dump destination which us usually $ORACLE_HOME/admin/<context>/udump You will see a series of trace files generated during the time of your issue reproduction. Tkprof all of the generated files and upload both the raw and tkprof files to your service request You can also check the user dump destination via the following: sql> show parameter user_dump_dest;

Versions of APPS Technology Stack Components

How to find the versions of technology stack components (Forms, iAS, Framework, JDK, OJSP, etc.)? Establish the needed environment parameters by sourcing the Applications environment file as the owner of the application tier file system. Ensure “APPLRGF” variable is set in environment. If not, set it to the same value as “APPLTMP”. Navigate to <FND_TOP>/patch/115/bin. Run the utility as follows: Operation System Command Line Unix or Linux perl $FND_TOP/patch/115/bin/TXKScript.pl \ -script=$FND_TOP/patch/115/bin/txkInventory.pl -txktop=$APPLTMP \ -contextfile=$CONTEXT_FILE \ -appspass=apps \ -outfile=$APPLTMP/Report_Inventory.html Windows perl %FND_TOP%\patch\115\bin\TXKScript.pl -script=%FND_TOP%\patch\115\bin\txkInventory.pl -txktop=%APPLTMP% -contextfile=%CONTEXT_FILE% -appspass=apps -outfile=%APPLTMP%\Report_Inventory.html Where: txktop Temporary working directory use by Perl Modules. Should not be an empty string. contextfile Location of the context file. If not passed, default is picked from the environment. appspass APPS schema password. If not passed, default password is used. outfile Location for the report being generated. If not passed, the default location is <APPLTMP>/TXK To generate the report in text format, the parameter “-reporttype=text” needs to be passed to the above commands. For example: outfile=$APPLTMP/Report_Inventory.html -reporttype=text Once the command executes successfully, it should generate the report file in the location specified for “outfile” parameter in above script Upload this file to Oracle Support for review.

Recovery catalog for RMAN

Creating the Recovery Catalog Owner

Start by creating a database schema (usually called rman). Assign an appropriate tablespace to it and grant

it the recovery_catalog_owner role. Look at this example:

% sqlplus ‘/ as sysdba’

SQL> CREATE USER rman IDENTIFIED BY rman
     DEFAULT TABLESPACE tools 
     TEMPORARY TABLESPACE temp
     QUOTA UNLIMITED ON tools;

SQL> GRANT CONNECT, RECOVERY_CATALOG_OWNER TO rman

Creating the Recovery Catalog

% rman catalog rman/rman@ORCL

RMAN> CREATE CATALOG;

Registering the target database

% rman TARGET / CATALOG rman/rman@ORCL

RMAN> REGISTER DATABASE;
