Basis Starter Guide User Rating: / 1 PoorBest Written by Tim van Steenbergen Monday, 02 July 2007 1 SAP R/3
This document is created to get a comprehensive list of all actions that I have taken during the maintenance of the SAP. This to make sure that I forget as little as possible.
This document can be a good handle for basis consultants who are starting on the job.
1.1 Tables
DBSTATC status of statistics-information per SAP-tableE070 Change-requests and their tasks and propertiesE071 Objects in change-requestsKNA1 Necessary at sapscript-ABAP’sMARA MateriallistPAT01, PAT03
Supportpackages and their status, also see table TEPSIN
TBATG Holds runtime-transportinformation (don’t know yet what it exactly holds)
TBTCO BatchjobinformationTTZZ Timezones. USR01 ~ ...12
Userdata
1.2 Transactions
Good advise: don’t learn the transactioncodes by heart at first, but use the menu-paths. This way you will sooner get an overview of the systems possibilities.
1.2.1 Daily maintenance
SM21 SystemlogSM37 Check the batchjobsSM50/51 Show all processes on one server / all serversSM66 Show all active process on the systemST11 Display developer-tracesST22 ABAP-dumps

1.2.5 Functional transactions
MM01,2,3 Create, Modify, Display material dataPP01,2,3 Create, Modify, Display productionplant dataVA01,2,3 Create, Modify, Display sales order data
1.3 Commands
/$sync Synchronise the buffers. ABAP’s on the application servers will be refreshed, so possibly changed. Not recommended on productionsystems in use.
/h Turning on the debugging mode/n New command/o New session
1.4 ABAP reports
RDDIMPDP Jobtriggerer. Starts the released batchjobs and tp-commands. RDDNEWPP To schedule RDDIMPDP, run this as DDIC in each targetclientRMMMPERI Periodclosing for MM. Gives problems regularly.RSCOLL00 Collector for system- and databasedata. Usually runs every hour.RSDBTIME Check and repair inconsistencies in the clocks of a systemRSEPSUPL Upload the patches available in /eps/in 31x?RSSUPC??

releasesRSTPTEST Tests the transporttoolRSUSRxxx User related reports (000 list active users, 002 userby comlex criteria,
etc)TOUCHALL Generate all ABAP’s. Takes about 24 hours!
1.5 Profileparameters
rdisp/* gui-parametersrdisp/gui_max_wait maximum time of no response (in 3.x: rdisp/gui_auto_logout)
1.6 Userids
1.6.1 Userids on SAP R/3 level
SAP* Sapsuperuser, has all authorizations. Its default password is available in the OSS.
DDIC Its default password is available in the OSS.
CPIC eh
1.6.2 Userids on databaselevel
SAPR3 User that connect SAP R/3 to the Oracle (or SQL or ..) database
OPS$ Oracle-only. Used to change passwords of OS-level userid’s. see OSS-note 50088
1.6.3 Userids on OS-level
<SID>adm os-administrator for unix-activities as creating logical volumes, filegroups, smit, smitty, etc
ora<SID> Oracle only: R/3-database administrator for SAPDBA-activities as brarchive, sapdba-analyze, brrestore, etc.
SAPService<SID> NT-only: OS-user used for running the service SAPOSCOL
1.6.4 Userid for applying Supportpackages
During applying supportpackages (aka. hotpackages) you need to be logged on to client 000 with a userid other then SAP*, but with the same authorizations.
1.6.5 Userid for configuring and maintaining STMS
During changing the Transport Management System using STMS you need to be logged on as TMSADM in client 000 on the transportdomaincontroller.
1.7 Logfiles
SAP logs almost any action and has a lot of trace-options. Here is a short listing for them:
• systemlog, viewed via transaction SM21, file stored in /work
• developertraces, viewed via ST11 or SM50 and doubleclick the process (as of 4.x), stored in /workdev_wX log for workproces number Xdev_ms log for workproces for the messageservicedev_gw log for workproces for the gatewaydev_disp log for workproces for the dispatcherdev_tp log for workproces for the transports
• startuplog, viewed via ST11
• stderrx, viewed via ST11, 3 or 4 files, hold more errorstatements
• trans.log, viewed via AL11, DIR_TRANS, transportlogfile
1.8 Traces
Tracefiles are very useful when analysing a problem.
• ST05 (System, Utilities, Performance trace) allows you to set a trace per user, transaction, program or process-id.
• SM50. Here you see the processes. Per proces you can see it’s corresponding tracefile via button ‘Show file’. The default trace-level is 1. You can change the tracelevel via Process, Trace, Dispatcher, Change tracelevel (of all processes, not per process).
2 Database
2.1 General databaseknowledge
Logging on to the database is done via:
• Log on as ora<SID>
• UNIX: svrmgrl (in Oracle 7.* this used to be ‘sqlplus’)
• NT: sqldba72 (or svrmgr23, svrmgr30)
• connect internal
2.1.1 Database-commands
2.1.1.1 SQL Select-statements
Select * from useful fields what does it do?dba_roles;dba_tables where tablespace_name=
’SYSTEM’ and owner=’SYS’;
shows all systemtables
sys.dba_role_privs; where grantee like ‘OPS$’; show the roles of the OPS$-user, should be: CONNECT, RESOURCE and SAPDBA.
v$backup shows which files are in backup mode
v$datafile; to verify the correct executionv$datafile where status not in
('SYSTEM','ONLINE')should be empty if SAP is online
v$dba_rollback_segs Data of all rollback segmentsv$log; shows all logfiles (4) and which
is activev$logfile; shows all physical logfiles
(mirrored, so: 8)v$nls_parameters where parameter =
'NLS_CHARACTERSET';returns the characterset with which the database is installed
v$recover_file; should be empty if SAP is onlinev$rollname Name and number of all
ONLINE rollback segmentsv$rollstat Number, status, optimal size,
diff. capacity sizes etc. of all ONLINE rollback segments
The V$-files contain the dynamic performance tables which hold the runtime information of R/3. To see all V$-files listed, go to ST04, detailed analysis, button display V$ values.
2.1.1.2 SQL Alter-statements
alter database open;
?alter database rename file '<device>:\<old path>\<old filename>' to '<device>:\<new path>\<new filename>';
alter system switch logfile; (4 times to perform four logswitches)
alter tablespace <tablespacename> end backup; the tablespace will end its status of being backed up.
2.1.1.3 SQL Other statements
analyze table <tablename> validate structure cascade;
drop tablename from ??; deletes the table from the database.
exit; logging out
grant user1 to user2; copies the rights of user1 to user2
saposcol –v show the version of saposcol
2.2 Oracle
2.2.1 important files
init<SID>.ora
init<SID>.sap
init<SID>.dba
2.2.2 OSlevel-commands
exit logging out
lsnrctl start start the oracle listener
lsnrctl status shows the status of the listener
tnsping <SID> tests the TNS-connection to the database
smit (or smitty) characterbased menu for handling of filesystems, logical volumes, drives etc.
2.2.3 Brbackup/brrestore
BRRESTORE –m file01/dir01 .. filen/dirn restore the backup and places the files in the given directories instead of the original directories
2.3 MS SQL
Logging on to the database is done via:
• Log on as <SID>adm?
• svrmgr30 or svrmgr (as of oracle 8.0)
• connect internal
checkdb to be added (or see microsoft/sql/ knowledgebase)
2.3.1 Services
SAP-Services that needs to be running on OS-level
• SAP<SID>_<Instance-number>
• SAPoscol
2.3.2 Stored procedures
sp_helpsort show the SQL-server’s sortorder and characterset (thus the codepage)
2.4 DB 2/400
enddbmon stop the databasecollector-program when it is running
3 Operating system
3.1 General
3.1.1 ftp
bin set transferring files to binary (as opposed to ascii)get download a file (mget doe not work on SAPSERVx)ls –l list directory, -l to show filedetailsput upload a file (mput does not work on SAPSERVx)pwd show current path
3.1.2 General commands
startsap r3 <SID> <profile>
Start SAP from the commandprompt
stopsap <SID> Stop SAP from the commandprompttp connect <SID> Tests if you can connect to the database of the system (start in
usr/sap/trans)r3trans –d –v Tests if you can connect to the databaser3trans –l filename Checks if the file is consistent and correct and can be imported
3.2 UNIX
3.2.1 Simple commands
chgrp grp filelist
Change the group that the file(s) belong to.
chmod 777 filelist
Change the rights of the file(s). 777: owner-world-user. 7: read-write-delete (=111)
chown user filelist
Change the owner of the file(s)
cp file1 file2 Copy file1 to file2cp /dev/null file
Clear all contents of file
errpt Hardware error-report (IBM-unix)ls –ltr <dir> Show filelist, –parameters: l: show fileattributes , t: sort by time, r:
reverse sortordermore <dir>mv file1 file2 Move commandps –ef Show all running processes, -e, -fvi The famous vi-editor
3.2.2 A little more complex commands
kill <PID> Kill a process as if it is cancelled. Child processes are killed as well.kill –1 <PID> Kill a process as if the user is logging out. Child processes are killed
as well.kill –9 <PID> Kill a process as brutal as possible. Child-processes are not touched.kill –USR2 <PID>
Increases TRACE by 1
kill –USR1 <PID>
Decreases TRACE by 1. When TRACE = 0 all open trace files are closed and can be cleared using ‘cp /dev/null filename’.
lslv Show the logical volumeslsvg Show the volumegroupssappfpar check pf=<profile>
Checks the profileparameter. Do they exist and do they have correct values.
set VAR VAL set environment variable VAR to value VALprintenv prints the environementvariablesps –ef |grep xxx
Monitor processes with name containing xxx
ps –u <username>
Monitor processes run by user <username>
Crontab
To schedule tasks you have to edit file crontab. Every line starts with five numbers and then a command. The numbers stand for minute, hour, day-of-month, month-of-year, day of week (0 for sunday).
The easiest way to edit the crontab file with a text-editor.
Detailed UNIX-commandlist
To get detailed information about every UNIX-command available and lots of articles, see site
AIX: www.rs6000.ibm.com/cgi-bin/ds_rslt
3.3 NT
at Schedule anything.hostname Shows the hostnameipconfig /all Show all ip-addresses of the systemipcs –m Show all IPC-processesipcrm –m <process>
Kill ipc-process <process>
regedit / regedt32
Edit the registry. (for instance HKLM, software, SAP)
sapntchk Checks the system, its ip-adresses, running processes etc.ntenv2reg Copy the environmentsettings to the registry to secure themntreg2env Copy the registry to the environmentsettings
4 General issues
4.1 SAP Tools
4.1.1 dpmon
This tool allows you to check SAP’s processes and to find out which one is killing the performance. Especially useful when it is not possible anymore to log on to your system.
(Oracle: use <SID>adm to start this tool)
dpmon Start dpmon, type m for the menu
4.1.2 gwmon
This tool allows you to check if the gateway is running. It is an addition to transaction SMGW.
4.1.3 R3load
R3load is used to:
- import/export databases
4.1.4 R3setup
R3setup is used to:
- install SAP-databases
- import exported databases into existing databases
4.1.5 R3trans
R3trans is used to:
- test databaseconnections
- import the transports
r3trans –d-v Tests the connection to the databaser3trans –l <filename> Tests if the datafileis corrupt or not
4.1.6 sapdba, to be run as ora<SID>
Sapdba is run to collect the data for the optimizer. This is done in two steps: First ‘SAPDBA –checkopt PSAP%’ checks which optimizerdata needs to be updated, then ‘SAPDBA –analyze DBSTATCO’ gathers the data of the objects to be updated.
sapdba –analyze DBSTATCO Gathers the optimizerdata that needs to be updatedsapdba –check <parameters> Checks the objects that you specify with its
parameterssapdba –checkopt PSAP% Checks which optimizerdata needs to be updatedsapdba –statistics Does all of the above in one run. See note 184513
4.1.7 saplicense, to be run from the ..\exe\run directory
saplicense –test pf=../../profile/default.pfl
Tests if the license is still valid
saplicense –get Gets the customer key (aka hardwarekey) need for the license
saplicense –install To install the licensekey received from SAPsaplicense –show Shows the current license
Request the license for the system by sending the fax included in the installation-kit to SAP.
4.1.8 saprouter
saprouter –r –R <saprouterfile> profile
Start the saprouter.
Table saprouttab p * * *(Permit/Deny, From-ip, To-ip, Service)
4.1.9 tp, to be run from the usr\sap\trans\bin
As of version 4.0 there is no more need for us to go down to the os-level. Everything can be done with transaction STMS. Nevertheless the tp-commands are still be useful and needed in some cases (yet). for detailed information on tp-command, see OSS-note 309711.
tp connect <SID> Tests the connection to <SID>tp locksys <SID> Lock the SAP-system for all users except SAP*tp unlocksys <SID> Unlock the SAP-system, giving access to all userstp showbuffer <SID> Show the buffertp addtobuffer <changerequest><SID>
Add the changerequest to the buffer. possible par.: u1
tp delfrombuffer <changerequest><SID>
Delete the changerequest from the buffer
tp import <changerequest> <SID> u.x
Importcommand, parameter u: u1: Import regardless if it is already imported or notu2: Overwrite the originals.u6: Overwrite objects in unconfirmed repairs.u8: Overwrite objects in open repairs
The returncodes for tp import command:
4 Warning
8 Error.
12/14/16 Fatal error
152 Nothing done
>1000 Returncode with extra information, but only the last three digits are relevant
The file TP_<DOMAIN>.PFL (used to be TPPARAM) in this directory holds the tp-parameter-settings
filesplit=yes|true|on(default=no)
Export will be split into files of size 2147483647 (2GB-1). Useful for OS’s that can not handle files larger then 2GB.
