SQL*Plus command line history completion

onlineappsdba — Fri, 20 Jun 2008 08:35:00 +0000

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

onlineappsdba — Fri, 20 Jun 2008 07:49:00 +0000

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

onlineappsdba — Thu, 19 Jun 2008 08:18:00 +0000

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

onlineappsdba — Thu, 19 Jun 2008 07:48:00 +0000

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 $s_apps_user/\n”);
system(“$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 $s_apps_user/\n”);
#system(“$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

onlineappsdba — Thu, 19 Jun 2008 07:39:00 +0000

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

Reference : Unix, Solaris, Linux, AIX, HP-UX Commands

onlineappsdba — Wed, 18 Jun 2008 16:05:00 +0000

As you know, there exists vast array of commands that enable you to do a multitude of tasks.

Depending on what you need to accomplish, you use only a certain subset of these commands.

These subsets differ from user to user and from need to need. However, there are a commands

that you commonly use. You need these commands either to answer your own questions or to

provide answers to the queries of the support professionals.

Create a User Event Trace in 11i / R12

onlineappsdba — Wed, 18 Jun 2008 11:58:00 +0000

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//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

onlineappsdba — Wed, 11 Jun 2008 09:43:00 +0000

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 /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 /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

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;
