      4.rdisp\vbname : Name of the server running where update are processed
      5.rdisp\vbreorg: It is used to delete the incomplete update request.
     1=delete, 0=no, we can also schedule a background job “RSM13002” but it will delete the update  
      request which are in completed it will be deleted after restarting.
      6.rdisp\vb_delete_after_execution: It is used to delete the update request soon after the execute of  
      the update. Set it to”1” to delete the record (or) “2” to the record will not be deleted. If it is set to “1”
      the background job “RSM13002” is not required. If not schedule periodically daily during off peak

     Shared locks: one user can read the tables and another one user can write the tables
     Exclusive locks: only a particular user can read it, nobody else can access it
     Cumulative locks: The same user with different transaction accessing the same table then the lock will
     be shared with user transactions

                              STMS: Sap Transport Management System

A. What is the transport?
    Transport is used to moving the object from one sap system to another sap system in the landscape.  
    Export the change request & import the transport request

B. The transport objects are divided into 2 types they are Export & Import
                                       DEV               QAS               PRO

                                                     Export                            Import
                                                  Central T.P Delivery at O.S level

C. What is domain controller?
     Domain control is a control all the systems in the landscape. It is used to manage all the transport
     parameters in the landscape. In the most of the environment there will be only one domain controller.

D. What is Transport domain controller?
     It is created as part of the post installation activity.

E. What is the transport domain & domain controller?
    At the sap level it is called as transport domain and at O.S level it is called as domain controller.

F. How to configure the domain controller?
    1.First decided which system you could like to define domain controller
    2.Login to the sap system with DDIC in client 000
    3.Go to SE06
    4.Click the post installation activity
    5.Go to STMS
    6.It will ask for the domain controller name
    7.Enter system ID of the domain controller
    8.Enter domain_<Sid> as domain controller name and enter the description
    9.Click save button

G. Steps to add the other system with domain controller
     10.   Logon domain controller system
      11.  Approve the added system

H. What is landscape?
     Landscape is arrangement of group of system to flow the objects
     DEV --------------------> QAS   -----------------------> PRO
     Landscape
     ECC            DEV ------> QAS -------> PRO
     EP               DEV ------> QAS -------> PRO
     BI                DEV ------> QAS -------> PRO
     Based on the customer requirements we can define the single, two, three and multi systems .in the
     landscape

I. In order to define landscape we need system
   1.Transport layer
   2.Transport root
   3.Transport group
   4.Transport target group
   5.Transport layer: transport layer is used to moving the object path from one system to another system
   within the landscape.
   Transport layers are 2 types they are
   Z<Sid> – customizing object move the Z<Sid> layer
   SAP – repository objects move the sap layer
   Transport routs: which shows from the transport direction to the target system?
   In three system landscape
   Dev -----> integrated system
   Qas -----> consolidated system
   Pro -----> delivery system
   Transport routs are 2 types they are
   Consolidated route: the route between development system to quality system is called consolidated route
   Delivery route: the route between quality systems to production system is called delivery route
   NOTE: In a two system landscape delivery route is not available
   Transport group: The systems which are shared a Trans directory is called                            transport
   group
   Transport target group: more than 3 systems & multiple clients it work’s on   extended transport controller
   is called transport target group
   Extended transport controller: it is used to transport objects within the client & system

J. What is the backup domain controller?
    Whenever primary domain controller is failed. In that time it will care of the transportation

K.  What is work flow?
      To set off the automatic process & responsibility of quality system

L.   Transport background jobs are RDDIMPDP, RDDNEWDP

M. Transport request are stored in TRBAT & TRJOB

N. All the change requests are stored table is E070
     1.E070 – Change request headers
     2.E071 – change request object lists
     3.E071k – object key contained within transports

O. At end of the import, transport specific the return codes

    hours


                                 Phases of the Support Package Manager

1. The Support Package Manager runs through a series of phases when it imports Support Packages. If you  
    want to know which phases were performed for which scenario (test scenario or standard scenario),
    execute program RSSPAM10.

2. The following list provides an overview of all the modules and phases and list them in the order in which  
    they are executed by the Support Package Manager:
                                               Module: Preparation
1. PROLOGUE
   This phase checks if you are authorized to import Support Packages.

2. CHECK_REQUIREMENTS
   This phase checks various prerequisites for importing Support Packages such as the tp logon to your
   system.

3. DISASSEMBLE
   This phase disassembles, or unpacks, the data files from the relevant EPS parcels and copies them to the
   transport directory.

4. ADD_TO_BUFFER
   This phase copies the queue to the transport buffer of your system.

5. MODIFY_BUFFER
    In this phase, the transport buffer is prepared for correct processing of the following import phases.

6. IMPORT_OBJECT_LIST
    This phase imports the object lists of the Support Packages in the queue into the system.

7. TEST_IMPORT
    This phase performs a test import for the current queue using tp. It checks if there are objects that are in

                                                      Kernel patch upgrade

A. What is the kernel patch upgrade?
     Kernel patch upgrade is a process of upgrading the executables files in the run directory with current
     version

B. What are prerequisites for applying kernel patch upgrationad?
    1) Before applying kernel patch we have to take online backup (or) off line backup of the system
    2) Before applying kernel patch we have to take backup of this folder usr\sap\<Sid>sys\exe\uc\nti386\run
    3) Stop the sap system and stop all the sap services
    4) Download the current kernel from www.service.sap.com
    5) Download the kernel files they are Database Independent & Database dependent
    6) After downloading this files with get the file format.car (or) .sar files
    t Ex: file format is SAPEXE_Patchlevel.sar (DB independent), file format SAPEXEDB_Patchlevel.sar
    (DB dependent)
    7) Extract the downloaded files from by using following command
     SAPCAR –XVF Filename.sar new folder
     SAPCAR –XVF SAPEXE_Patchlevel.sar
     SAPCAR –XVF SAPEXEDB_Patchlevel.sar
    8) The files will be in the format of .EXE (or) .DLL (or) .DB ……..ext

C. How to apply the kernel?
    Take the extracted files from new folder and replace the existing kernel usr\sap\<Sid>\exe\uc\nti386\run
     with newly extracted files
    Once replacement has finished we need to start the services
    Go to services.msc then select the following files are started
    Go to MMC select the instance click the start button
    Once sap system is up & running check the kernel version
    Go to cmd prompt -----> disp+work (it will show the upgrade kernel version)

D. How to get the sap kernel files?
     Logon market place ---> s/w downloads ---> entry by application group ---> additional component ---
     > click0n  sap kernel (32 bit uc, 64 bit uc, 32 bit nuc, 64 bit nuc.)
    Once database independent is completed after that Database dependent completed

E. usr\sap\<Sid>\sys\exe\uc\nti386\run
    Run directory is called as a kernel directory
    This stores all the executables through which sap runs

F. Kernel is provided the communication between SAP, DB & O.S

     Cmd – sqlplus /as sysdba (enter)
     SQL :> select status from v$ instance;
    Open (or) mount (or) no mount (or) not available

H. If oracle is not coming up we need to start it
     SQL :> startup [to open the oracle]

I. Oracle blocks may be corrupted (we need to recover the data]

J. Ora arch directory may be full [backup & delete the old data]

K. Table space issues (or) space issues at O.S level [then increase the table space issues (or) increase O.S
     level spaces]

L. Dispatcher is not coming up in that time we have to check the listener
    Cmd: lsnctl (enter)
    Listener :> status (to check whether it is started or not
    Listener :> start [to start the listener]
    Listeners :> stop [to stop the listener]

M. If system is not coming up then change in instance profile that is rdisp\trace = 0, 1,2,3,4 then start sap
      again it will writes the logs into work directory (after starting sap system we need to change the trace
      level = “0”)
     [Trace = 0 – no trace is written to files]
     [Trace =1 – write error messages in the trace file]

P. How to db client connect to oracle?
    LISTNER will provide the connectivity between the sap system and database during startup of sap system
    During the starting of sap system LISTNER will create shadow process in the ratio of 1:1 to connect to
    database

Q. LISTNER: create the shadow process which are going to connect the database table “SAPUSER” by
     using ops$ mechanism
    Ops$ mechanism contain the one table in database, that table is “SAPUSER” this table contains schema
    owner name & password. Shadow work process get the scheme owner name & pass word, disconnect 
    (choose connection database) the database.
    Shadow process again connects to database by using schema owner name & password.

R. What is the ops$ mechanism:
     The user who is authorized at o.s level is automatically authenticared at Database level. That means no
     user ID & password is required to login to Database
     It is provide the 2 parameters are contained in RZ10 T_Code
     OS_authent_prefix = ops$
    Remote_OS_authent = true

Local memory: local memory is associated with individual work process, local memory is executables, data, stack, buffer for data transfer, local roll area, local paging area.
Shared memory: shared memory is associated with all the process of one instance R/3 buffer contains global objects for all users and work process such as programs and customizing tables.
Heap memory: it contains user context, when extended memory is full. It is called and released on demand.
The six R/3 memory areas are:
Buffers, extended memory, heap memory, roll memory, R/3 paging memory, local work process memory.
What is roll area & page area?
Roll area: user context data is store of that is authorizations, set/get parametes, internal tables and report lists.
Paging area: which stores application program data that corresponding to specific Abap commands?
Parameters:
Ztta/roll_first – define first port of the roll area set to 1.17kb to 4.6
Ztta/roll_extention – extended memory
Ztta/roll_area – total roll area for work process
Ztta/roll_shm – the size of the roll buffers
Ztta/roll_maxfs – the size of the roll buffers and roll file
Em/intial_size_mb – the fixed size of extended memory
Em/address_space_mb – amount of extended memory for work process
Abap/heap_area_total – total amount of heap memory allocated to all work process
Abap/heap_area_dia – limit for the amount of local memory allocated to dialog work process
Abap/heap_area_media – amount of local memory allocated to dialog work process
Abap/heaplimits – maximum heap limit – if it is reached the work process is flogged  for restart
Heap memory is released after use. After ending the transaction the heap memory is automatically released and the work process restarted to release the swap memory.
Oracle startup options: startup no mounts: oracle is not operational and oracle background process is not started. It will used to create the control file.
Startup mount: oracle is not open and not operational. Oracle background process is started. SGA is created [SGA means shared global area]
Startup: oracle is open and operational
Oracle shutdown 4 types the are
Abort
Immediate
Transactional
Normal
Abort: here we forcefully shutdown the database without intimating any users. The total cache information in the lost and SMON can recover the information from online redo log files whenever system is restarts
Immediate: the committed transactions are updated in to the database. the database open transactions are rolled back
Transactional: open transactional are successfully updated in to the database. No need connections are not allowed. Shutdown is normal transactions are also not allowed.
Normal: no connections are allowed exist user can perform transaction till complete the task
Oracle files structure:
Oracle – sid – sapdata1
Oracle – sai – sapdata2
Oracle – sai – sapdatan
Oracle – sid – sap backup
Oracle – sid – sap arch [recover purpose data]
Oracle – sid – sap trace – user trace – trace file
Oracle – sid sap trace – background trace – alter_<Sid>.trace [it contain all profile in formation about oracle]
Oravle – sid – orig log A [online redo log files & control files]
Oravle – sid – orig log B [online redo log files & control files]
Oracle – sid – mirror log A [mirror of orig log files]
Oracle – sid – mirror log B [mirror of orig log files]
Oracle – sid - Ora arch [off line redo logs
Control file: it contains the oracle structure. It is a binary file. It can be updated only oracle. We can’t edit manually.
If lot of achieve logs are getting generated in minutes then what do we do?
Increase the redo log file size
What is your database size?
Start from 500 GB
What is your database growth?
Monthly 20 GB (or) 30 GB growth
What do you check in DB02?
Table space utilization, space critical objects and table space growth
What is your action, if any space critical objects are there?
Go to DB02, click on space critical objects, then note down the objects, go to SAPDBA, go to reorganization (option d), then use option b ---> show extent ---> resize the extent (take the recommended value)
How do you check the backup log?
In sap level – DB12
In OS level (log in as <Sid>adm)
Go to oracle/<Sid>/sap backup
# Tail back<Sid>.log
What is sap scheduler (or) database backup?
DB calendar (DB13)
What file is responsible for sap backup?
Init<Sid>.sap
What is your backup strategy?
We do daily on line backup on all servers and weekly offline backup on DEV and Quality system

Why mapping?
The user ID’s are particular system & back end system are different then we need to perform the user mapping
DB02: this transaction is used for checking the database table space
What are the table spaces?
System – oracle table spaces
Sysaux – oracle table spaces
Psapsr3 – component specific
Psapsr3700
Paspsr3usr
Psapundo – for roll back information
Psapremp
If abap+java stack are one more table is added
Psapsr3db
Db backup calendar transaction code is – DB13
Db backup logs transaction code is – DB12
Data base log & BRTOOLS logs transaction code is – DB14 & DB24
To check the performance of the Database transaction code is – ST04
How to add the data files for database table space?
Brspace –f tsextended –t <tablename> (enter)




What are the database initialization files?
Init <Sid>.ora ---> p file
Sp file<Sid>.ora ---> sp file
Init<Sid>.ora
Init<Sid>.sap
What is the difference between p file & sp file?
P file is the static file, it is a test file and we can edit manually by using notepad.
Sp file is server parameter file. It is a binary file and we can’t edit the manually. It can modified with the ALTER SYSTEM SET command
# alter system set timed statistics = true scope = both;
Init <Sid>.sap is used for generation of BRTOOLS option
Database locks transaction code is – DB01
Workload analysis transaction code is – ST03 & ST03N
Here we can see database response time 150millisecinods
CPU response time is 150ms
Rollin/rollout response time 50ms
GUI response time 200ms
RFC response time 200ms

Log_archive_start = true ---> indicates to automatically start the archive process when the database is start
Log_archive_dest ---> archiving directory for offline redo log files
Db_block_size ---> specifies the size of  the oracle block in bytes
Db_block_buffer --->total no. of data buffer in SGA
Shared_pool_size ---> specifies in bytes the amount of space that SGA reserved to cashed & SQL start
Log_buffer ---> space allocated to the redo log buffers
Disk_copy ---> it is used for copying the database to disk
Why we need to DB refresh?
To test the object or changes which are made to system like production environment. We need to restore the production data to QAS data.
What are homogeneous system copy & heterogeneous system copy and how you will do that?
A system copy without a change in the database type and the OS is called a homogeneous system copy.
A system copy with a change in the database type and the operating system is called a heterogeneous system copy

What is db refresh?
It is the process of refreshing the data of one system by another system [OS, DB & R3] remains the same but only database is refreshed
Pre steps for db refresh?
Create the transport of copies by using SE01 and specify the following tables are USR01, USR02, RFCDES and TBDLS. Then we need to release the transport of copies.
Copy the cofiles & datafiles in usr\sap\<Sid>\trans
Take the screen shots of SM59, BD54, DB13, SM37, AL11, SMLG, RZ12, RZ04, SCC4 & SPAM
And then we need to delete all the datafiles related to QAS system. Data1, Data2 ---- ext first we need to stop the oracle services, the structure should remain same
Directories like sapdata1 ……….sap data n
Mirrorloga
Mirror log b
Orig log a
Orig log b
Copy the sap back up folder from PRD, along with the control.sql file pasted on the desk top to QAS (\oracle\QAS\sap backup)
Open the .afd/.and backup file (ex: bdjvujux.afd) present in sap directory. Replace the PRD with the QAS and save it
Go to \oracle\QAS\sap backup\**** (ex: bdjvux.afd) backup filename folder; location rename the files with PRD to QAS
Start ---> run ---> cmd goes to the location \oracle\QAS\sap backup and type
Brrestore –m full –b <file name>.afd –c (backup is restored success fully)
Check the present of the paths for the creation of the control file oracle
\Oracle\Qas\orig log A\cntrl
\Oracle\Qas\orig log B\cntrl
\Oracle\Qas\sapdata1\cntrl
If one of these path is not created . then create it
Start the oracle services

Copy that file and paste it onto the desktop and rename it with control.sql
Open the control.sql file and perform the following
Remove the lines present above “startupnomount” and below “charactersetutfs” and save the file
Replace the <source SID> with <target SID>
Example: here it is from PRD to QAS
Replace REUSE with SET
Replace NORESETLOGS with RESETLOGS
Replace ARCHIVELOG with NOARCHIVELOG
After control file is created , the oracle is in mounted state

The Following are the transaction codes used for the System Monitoring:
SM12:
This Traction is used for Check for Lock Entries. There may be old locks still in place from transactions that did not release, or from when the user was cut off from the Network. If any lock entries are exist then we have to check since how long this lock existing. If, this lock existing from more than one day then we should check that particular User is available or not (By using the Transaction Code AL08). If he is not available then Delete that lock. Otherwise we should wait 1 or 2 Days.

SM13 :
This Transaction is used for Check for any Errors in Update Records. A failed or “Update Terminate” is an update to the failed database. These failed Updates occurs when a user entry or transaction is not entered or Updated in database. And we should check Whether Update is ACTIVE or not. And also we should check any Update Records are terminated.

SM21 :
This Transaction is used to check System Logs. After hitting the traction we should goto System log--> Chooseà All Remote System logs, and set Date and time to before the Last log review. And we should check whether any Errors, Warnings, Security Messages, Database, Abends, Any other different Events are there.The log is important because unexpected or unknown warnings and errors could indicate a serious problem.

SM51 :
This Transaction is used to check that all Application Servers are UP. And also This transaction is a central transaction from which you can select the instance to be monitor.

SM50 :
This Transaction is used to check Work Process Overview and for Systems with out Servers. Here all work processes with a “Running” or “Waiting” State. If Batch Jobs are not Running, If all the work processes are in use, this transaction provide a hint of this problem.

ST01 :
This Transaction is used for System Trace. By this transaction we can trace that what are the operations performed on particular file by particular user on which dates.

ST02 :
This transaction is used for Buffer tuning or Buffer Statistics. And it is used to tune Buffer perameters of R/3. The Buffer is important because significant buffer swaping reduces performance. Look under “Swaps” for Red Entries. Regularly check these entries to establish trends and get a feel of the Buffer behaviour. And in this transaction we should Maintain “Hit Ratio” is in between 90 – 100% for all , and “Heap Memory” allocated should be “0” , and “Swaps” is 0.

ST03 :
This Transaction is used to Check Work Load Analysis of. Workload Analysis is used to determine System performance. Check Statistics and Record Trends to get a feel for the System’s Behaviour and Performance. Understanding the System when it is running well helps us to determine what changes may need to be made when it is not.

ST04 :
This Transaction is used for Database Performance Analysis. This transaction provides the ability to Monitor the Database in related to 1) In Shared Pool “SQL Area Get Ratio” should be 90 – 95% 2) In Log Buffer Allocation Retries / Entries <1% 3) In Data Buffer “Quality” should be in 90 – 95% 4) In Sorts Disk / Memory <1% 5) In Table Scan & Fetches “Long Table Scans” should maintain as minimum as possible. And we should check Detailed Analysis then we should hit “Detailed Analysis menu” Button in this screen. In that we can check Database Overview like “Exclusive Lock Waits” , “Wait Events”, “Buffer Busy Waits”, “ File System Request”, “ Database Message logs”, “ SQL Requests”, Summery Report for all activities, etc

ST22 :
This Transaction is used to Analyse ABAP Dumps or Short Dumps. This transaction is also used for Analyse and Determine why the error occurred and take corrective action. It looks for an excessive number of dumps, and also dumps of an unusual nature. A ABAP dump is generated when a report or transaction terminates as a result of a serious error. The system records in the System Log(SM21) and writes a snapshot of the program terminate to a special table.

DB02 :
This transaction is used to check all table Spaces and Indexes. Here we should check table spaces sizes. If any table used space is =>99 then we should increase add the space for particular table space. And this transaction is provides a way to examine database allocation. And this transaction is allows us to monitor items such as: a) DB Space History b) DB Analysis By this transaction we can view Database history by Dates and Times.

DB12 :
This Transaction is used to check database Backups. And in this we should we see successful Backups and Unsuccessful Backups list

AL08 :
This transaction is used to Check the users on the System. This transaction displays User Ids and Terminal Names who are currently logged on the system.

SM37 :
This transaction is used for Monitoring Background Jobs. Background are batch jobs scheduled to run at specific time during the day. Here we should check for cancelled jobs. Here If we want to check particular job then,we should enter the Job Name and enter User name in User name field or ‘*’ and hit execute Button. And verify that all critical jobs are successful.









T_Code             Description                            Action
SM66 1. Check Long running job. (Job running for more than 12 hours (43200Secs)
2. Check the status for all work processes. There should not be lot of dialog work processes in PRIV mode. 1 You can Send a mail to user confirming the runtime for the same.
