Difference between Oracle Apps 11i and R12 (Technical)

Major technical difference: - 

Database Version in 11i (11.5.9 & 11.5.10) was 9i Rel 2 where as in Release 12 its 10g R2 (

Application Tier:Tech Stack in Application Tier consist of iAS( & Developer 6i (Forms & Reports 8.0.6) but in Applications R12 it is build on Fusion Middleware (10g Web Server and 10g Forms & Reports)

Sub component in Application TierA) HTTP Server or Web Server in R12 is Version 10.1.3 which is built on Apache version 1.3.34. In apps 11i it is Version built on Apache Version 1.3.19
B) Jserv in apps 11i is replaced by OC4J (mod_jserv is replaced by mod_oc4j)
C) Forms Version 6i in Apps 11i is replaced by Forms in R12
D) Reports Version 6i in Apps 11i is replaced by Reports in R12
E) JDBC version is changed from version 9 in apps 11i to version 10.2.0 in Apps R12
F) modplsql or mod_pls is removed from Apps R12
G) Java processes use JDK/JRE version 1.5.0 in R12 against JDK version 1.3.1 or 1.4.2 in Apps 11i
H) For various environment variable changes check below picture : -

I) New top INSTANCE_TOP added in Release 12 for configuration and log files: -


Oracle Apps R12 File System Changes: -

new TOP (INSTANCE_TOP) in Application Tier.

If you are familiar with Oracle Apps 11i , you can easily understand picture on your right. This is file system for 11i with various TOP's , APPL_TOP, ORA_TOP, COMMON_TOP, DB_TOP and DATA_TOP. With Multiple Middle Tier configuration came shared APPL_TOP (only APPL_TOP used to be shared ) . After shared  APPL_TOP came shared Application Tier (All three TOP's on Application Tier, APPL_TOP, ORA_TOP and COMMON_TOP were shared across servers). With this came challenge of configuration files which are specific to a server mainly iAS & 806 configuration file. If you have configured Shared Application Tier (sharing ORA_TOP as well) in 11i then this problem was overcome by creating conf directory in COMMON_TOP.

In Oracle Apps R12, You can see new TOP called INSTANCE_TOP in Application Tier. This TOP will now hold any configuration files (specific to that server) , Certificates (If SSL is enabled SSL Certificates & any other certificates specific to that server) and related log files or pid files (for Apache or any other process). In diagram tops with <>ST can be shared across servers (Shared Tier) and INSTANCE_TOP will be specific to Server.

Next three pictures are taken from Ivo Dujmovic's presentation at Oracle Open World "Deep Dive: Oracle E-Business Suite Release 12 New Technology Stack". These Pictures are self explanatory & will help you in understanding Oracle Apps R12 File System.
This shows Oracle E-Business Suite Release 12 File System Layout

This shows Directory/File Structure for Instance TOP in R12

This Picture compares file system in 11i with File system in R12

Middle/Application Tier Scripts in R12

Scripts for Application Tier services in R12 are located in
where CONTEXT_NAME is of format SID_HOSTNAME

Master script to start all components/services of middle tier or application tier. This script will use Service Control API to start all services which are enabled after checking them in context file (SID_HOSTNAME.xml or CONTEXT_NAME.xml)

Master script to stop all components/services of middle tier or application tier.

Script to start / stop apps listener (FNDFS and FNDFS). This listener will file will be in 10.1.2 ORACLE_HOME (i.e. Forms & Reports Home)
listener.ora file will be in $INST_TOP/apps/$CONTEXT_NAME/ora/10.1.2/network/admin directory
(Mostly similar to one in 11i with only change in ORACLE_HOME i.e. from 8.0.6 to 10.1.2 )

iv) adapcctl.shScript to start/stop Web Server or Oracle HTTP Server. This script uses opmn (Oracle Process Manager and Notification Server) with syntax similar to opmnctl [startstop]proc ohslike opmnctl stopproc ohs .

(In 11i this script directly used to call apachectl executable but now calls opmnctl which in turn calls apachectl. In 11i web server oracle home was but in R12 its 10.1.3)

Script to start / stop concurrent manager, Similar to one in 11i. (This script in turn calls )

Script to start / stop Forms OC4J from 10.1.3 Oracle_Home. This script will also use opmnctl to start/stop Forms OC4J like
opmnctl stopproc type=oc4j instancename=forms

This script is used only if you wish to start forms in socket mode. Default forms connect method in R12 is servlet.
If started this will start frmsrv executable from 10.1.2 Oracle_Home in Apps R12
This script will start/stop oacore OC4J in 10.1.3 Oracle_Home. This scripts will also use opmnctl (similar to adapcctl & adformsctl) to start oacore instance of OC4J like
opmnctl startproc type=oc4j instancename=oacore

ix) adoafmctl.shThis script will start/stop oafm OC4J in 10.1.3 Oracle_Home. This scripts will also use opmnctl (similar to above) to start oacore instance of OC4J like
opmnctl startproc type=oc4j instancename=oafm

This script will start/stop opmn service in 10.1.3 Oracle_Home. opmn will control all services in 10.1.3 Oracle_Home like web server or various oc4j instances. If any services are stopped abnormally opmn will/should start them automatically.

This script will be used to start/stop one to one fulfilment server.

To start / stop mwa telnet server where mwa is mobile application.

Log File Location for Startup Shutdown Services in R12
Log files for startup/shutdown scripts for application/mid tier in R12 are in $INST_TOP/apps/$CONTEXT_NAME/logs/appl/admin/log(adalnctl.txt, adapcctl.txt, adcmctl.txt, adformsctl.txt, adoacorectl.txt, adoafmctl.txt, adopmnctl.txt, adstrtal.log, jtffmctl.txt )

To find space used by a database user

Query to find space used by a database user. Following query can be used to know the space used by the logged in user in MBs:

SELECT sum(bytes)/1024/1024 user_size FROM user_segments;

Query to find the space occupied by all the users in a database. This requires access to dba_segments table:

SELECT owner, sum(bytes)/1024/1024 total_size FROM dba_segments
GROUP BY owner ORDER BY total_size DESC;

Total space occupied by all users:

SELECT sum(bytes)/1024/1024 total_size FROM dba_segments;

To find Database Size

The database mainly comprises of datafiles, temp files and redo log files.
The biggest portion of a database’s size comes from the datafiles.

To find out how many megabytes are allocated to all datafiles:
SELECT sum(bytes)/1024/1024 data_size FROM dba_data_files;

To get the size of all TEMP files:
SELECT nvl(sum(bytes),0)/1024/1024 temp_size FROM dba_temp_files;

To get the size of the on-line redo-logs:
SELECT sum(bytes)/1024/1024 redo_size FROM sys.v_$log;

Finally, summing up the three above, total database size can be found:
SELECT (dsize.data_size + tsize.temp_size + rsize.redo_size)/1024/1024 "total_size"
FROM (SELECT sum(bytes) data_size
FROM dba_data_files ) dsize,
(SELECT nvl(sum(bytes),0) temp_size
FROM dba_temp_files ) tsize,
(SELECT sum(bytes) redo_size
FROM sys.v_$log ) rsize;

To find free space in temporary tablesapce:

SELECT tablespace_name,SUM(bytes_used),SUM(bytes_free) FROM V$temp_space_header GROUP BY tablespace_name;

To find tablespace free space in a database

SELECT a.tablespace_name, a.file_name, a.bytes allocated_bytes,
FROM dba_data_files a,
(SELECT file_id, SUM(bytes) free_bytes
FROM dba_free_space b GROUP BY file_id) b

Steps to resolve locks on database

Error Message:Could Not Reserve Records Due to Database Record Lock

1. Identify the Oracle serial ID, SID ID and terminate without shutting the
database down.

1.1 Make sure that the user is logged off.

1.1.1 Type ps -ef |grep

1.1.2 Kill all processes related to that user.

1.2 Identify SID, serial#

select distinct
acc.object, ses.osuser, ses.process,
ses.sid, ses.serial#
from v$access acc,
v$session ses
where (acc.owner != 'SYS'
or acc.object = 'PLAN_TABLE')
and acc.sid = ses.sid
and ses.status != 'INACTIVE'
and ses.type != 'BACKGROUND'
and acc.object not in ('V$ACCESS','V$SESSION')
and ses.audsid != userenv('SESSIONID')
order by 1,2,3

1.3. Double-check the identified SID and serial ID:

SELECT osuser,
to_char(logon_time,'DD-MON HH24:MI:SS') logon_time,
FROM v$session

Alternatively use the following scripts to identify the blocking session:

-- check for locked tables
select a.object_id, a.session_id, substr(b.object_name, 1, 40)
from v$locked_object a,
dba_objects b
where a.object_id = b.object_id
order by b.object_name ;

select sid,
decode(block ,0,'NO','YES') BLOCKER,
decode(request,0,'NO','YES') WAITER
from v$lock
where request > 0 or block > 0 order by block desc

SELECT 'alter system kill session '''||vs.sid||','||vs.serial#||'''' ,al.
object_name, al.object_type, vs.status,
to_char(vs.logon_time,'DD-MON HH24:MI:SS') logon_time, vs.program
FROM fnd_logins fl, fnd_user fu, all_objects al, v$lock vl, v$session vs
WHERE = vl.sid
AND vl.id1 = al.object_id (+)
AND fl.user_id = fu.user_id
AND to_char (start_time, 'DD-MON-RR') = to_char (sysdate, 'DD-MON-RR')

Control File Autobackups

One of the many features included in rman is the ability to automatically backup your control file. What is a control file? The control file contains information about your database including its physical structure. If you are using rman without a recovery catalog then your backup information is also stored in the control file.

It is very important for (some) recovery purposes to ensure you have a recent copy of your control file, especially if it contains your recovery catalog. There is one feature of control file autobackups which alot of dba's seem to be unfamiliar with, which is why I thought i'd write up a brief article on it. If you have this feature enabled and you make a structural change to the database, the control file is automatically backed up. ie, If you add a datafile, rename a file, etc. Information which could affect your ability to recover. This backup will be placed on disk even if your regular backup goes to tape.

A quick test. First, ensure you have control file autobackups enabled and select a location on disk. By default the control file backup will be placed in your $ORACLE_HOME/dbs directory unless you specify a location.

drwxrwxr-x 2 oravis dba 512 Jan 16 15:25 .

Next we need to make a structural change to the database to see if the control file is automatically backed up. For this example i'll add a small datafile to the system tablespace.

SQL> alter tablespace SYSTEM add datafile '/oradata/dbf/visdata/system09.dbf' size 25M;

Tablespace altered.

A directory listing of the backup location should show a second control file backup:

oravis@myserver=> ls -alrt /oradata/bck/vis_backup

R12: Changing apps password

In 11i there were a few steps in order to change the apps password.

1. Shutdown the environment.
2. execute FNDCPASS to change the apps password.
Ex. FNDCPASS apps/[oldpassword] 0 Y system/[system password] SYSTEM APPLSYS [new apps password]

3. Manually modify files such as appsweb.cfg and
4. Startup the environment.

In R12:

1. Shutdown the environment.
2. Execute FNDCPASS as above.
3. Run Autoconfig
4. Startup the environment.

I realized the process had changed when I looked at the file and noticed the following:

; $Header: 120.0.12000000.2 2007/06/29 11:43:45 sbandla ship $
; $AutoConfig$
; Not required in R12. Stubbing the file from %s_fndtop%/admin/template

Cloning from an RMAN backup using duplicate database - R12

Cloning Oracle Applications Release 12 with Rapid Clone.

Here are the steps:
  1. Execute preclone on all tiers of the source system. This includes both the database and application tiers. (For this example, TEST is my source system.)

    For the database execute: $ORACLE_HOME/appsutil/scripts/<context>/ dbTier
    Where context name is of the format <sid>_<hostname>

    For the application tier: $ADMIN_SCRIPTS_HOME/ appsTier
  2. Prepare the files needed for the clone and copy them to the target server.
    • Take a FULL rman backup and copy the files to the target server and place them in the identical path. ie. if your rman backups go to /u01/backup on the source server, place them in /u01/backup on the destination server. To be safe, you may want to copy some of the archive files generated while the database was being backed up. Place them in an identical path on the target server as well.
    • Application Tier: tar up the application files and copy them to the destination server. The cloning document referenced above ask you to take a copy of the $APPL_TOP, $COMMON_TOP, $IAS_ORACLE_HOME and $ORACLE_HOME. Normally I just tar up the System Base Directory, which is the root directory for your application files.
    • Database Tier: tar up the database $ORACLE_HOME.

      ex. from a single tier system. The first tar file contains the application files and the second is the database $ORACLE_HOME

      [oratest@myserver TEST]$ pwd
      [oratest@myserver TEST]$ ls
      apps db inst
      [oratest@myserver TEST]$ tar cvfzp TEST_apps_inst_myserver.tar.gz apps inst
      [oratest@myserver TEST]$ tar cvfzp TEST_dbhome_myserver.tar.gz db/tech_st

      Notice for the database $ORACLE_HOME I only added the db/tech_st directory to the archive. The reason is that the database files are under db/apps_st and we don't need those.
    • Copy the tar files to the destination server, create a directory for your new environment, for example /u01/DEV. (For the purpose of this article I will be using /u01/DEV as the system base for the target envrionment we are building and myserver is the server name.)
    • Extract each of the tar files with the command tar xvfzp

      Ex. tar xvfzp TEST_apps_inst_myserver.tar.gz
  3. Configure the target system.
    • On the database tier execute with the dbTechStack parameter.

      For example. /u01/DEV/db/tech_st/10.2.0/appsutil/clone/bin/ dbTechStack

      By passing the dbTechStack parameter we are tell the script to configure only the necessary $ORACLE_HOME files such as the init file for the new environment, listener.ora, database environment settings file, etc. It will also start the listener.

      You will be prompted the standard post cloning questions such as the SID of the new environment, number of DATA_TOPS, Oracle Home location, port settings, etc.

      Once this is complete goto /u01/DEV/db/tech_st/10.2.0 and execute the environment settings file to make sure your environment is set correctly.

      [oradev@myserver 10.2.0] . ./DEV_myserver.env
  4. Duplicate the source database to the target.
    • In order to duplicate the source database you'll need to know the scn value to recover to. There are two wasy to do this. The first is to login to your rman catalog, find the Chk SCN of the files in the last backupset of your rman backup and add 1 to it.

      Ex. Output from a rman> List backups
      List of Datafiles in backup set 55729
      File LV Type Ckp SCN Ckp Time Name
      ---- -- ---- ---------- --------- ----
      7 1 Incr 5965309363843 15-JUN-09 /u02/TEST/db/apps_st/data/owad01.dbf

      So in this case the SCN we would be recovery to is 5965309363843 + 1 = 5965309363844.

      The other method is to login to the rman catalog via sqlplus and execute the following query:

      select max(absolute_fuzzy_change#)+1,
      from rc_backup_datafile;

      Use which ever value is greater.
    • Modify the db_file_name_convert and log_file_name convert parameters in the target init file. Example:

      db_file_name_convert=('/u02/PROD/db/apps_st/data/', '/u02/DEV/db/apps_st/data/',
      '/u01/PROD/db/apps_st/data/', '/u02/DEV/db/apps_st/data/')

      log_file_name_convert=(/u02/PROD/db/apps_st/data/', '/u02/DEV/db/apps_st/data/',
      '/u01/PROD/db/apps_st/data/', '/u02/DEV/db/apps_st/data/')
    • Verify you can connect to source system from the target as sysdba. You will need to add a tns entry to the $TNS_ADMIN/tnsnames.ora file for the source system.
    • Duplicate the database. Before we use rman to duplicate the source database we need to start the target database in nomount mode.

      Start rman:

      rman target sys/<syspass>@TEST catalog rman/rman@RMAN auxiliary /

      If there are no connection errors duplicate the database with the following script:

      run {
      set until scn 5965309363844;
      allocate auxiliary channel ch1 type disk;
      allocate auxiliary channel ch2 type disk;
      duplicate target database to DEV }

      The most common errors at this point are connection errors to the source database and rman catalog. As well, if the log_file_name_convert and db_file_name_convert parameters are not set properly you will see errors. Fix the problems, login with rman again and re-execute the script.

      When the rman duplicate has finished the database will be open and ready to proceed with the next steps.
    • Execute the library update script:

      cd $ORACLE_HOME/appsutil/install/DEV_myserver where DEV_myserver is the <context_name> of the new environment.

      sqlplus "/ as sysdba"@adupdlib.sql

      If your on linux replace with so, HPUX with sl and for windows servers leave blank.
    • Configure the target database

      cd $ORACLE_HOME/appsutil/clone/bin/ dbconfig

      Where is $ORACLE_HOME/appsutil/DEV_myserver.xml
  5. Configure the application tier.

    cd /u01/DEV/apps/apps_st/comn/clone/bin
    perl appsTier

    You will be prompted the standard cloning questions consisting of the system base directories, which services you want enabled, port pool, etc. Make sure you choose the same port pool as you did when configuring the database tier in step 3.

    Once that is finished, initialize your environment by executing

    . /u01/DEV/apps/apps_st/appl/APPSDEV_myserver.env

  6. Shutdown the application tier.

    ./ apps/<source apps pass>
  7. Login as apps to the database and execute:

    exec fnd_conc_clone.setup_clean;

    I don't believe this step is necessary but if you don't do this you will see references to your source environment in the FND_% tables. Every time you execute this procedure you need to run autoconfig on each of the tiers (db and application). We will get to that in a second.
  8. Change the apps password. Chances are you don't want to have the same apps password as the source database, so its best to change it now while the environment is down.

    With the apps tier environment initialized:

    FNDCPASS apps/<source apps pass> 0 Y system/<source system pass>> SYSTEM APPLSYS <new apps pass>
  9. Run autoconfig on both the db tier and application tier.

    db tier:
    cd $ORACLE_HOME/appsutil/scripts/DEV_myserver

    Application Tier
  10. If there are no errors with autoconfig start the application. Your already in the $ADMIN_SCRIPTS_HOME so just execute:

    ./ apps/<new apps pass>
  11. Login to the application and perform any post cloning activities. You may want to override the work flow email address so that notifications goto a test/dev mailbox instead of users. We always change the colors and site_name profile options, etc. More details can be found in Section 3: Finishing tasks of the R12 cloning document referenced earlier.
Thats it, hopefully now you have successfully cloning an EBS environment using rman duplicate.
