    Supportpackages and their status, also see table TEPSIN

    TBATG Holds runtime-transportinformation (dont know yet what it exactlyholds)

    TBTCO Batchjobinformation

    TTZZ Timezones.USR01~ ...12

    Userdata

    1.2 Transactions

    Good advise: dont learn the transactioncodes by heart at first, but use the menu-paths.This way you will sooner get an overview of the systems possibilities.

    1.4 ABAP reports

  • 7/30/2019 Basis for Starters

    3/12

    RDDIMPDP Jobtriggerer. Starts the released batchjobs and tp-commands.

    RDDNEWPP To schedule RDDIMPDP, run this as DDIC in each targetclient

    RMMMPERI 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 system

    RSEPSUPL Upload the patches available in /eps/in 31x?RSSUPC?? Generates the profiles and activitygroups

    RSPARAM Shows the parametersettings of a running SAP-instance

    RSPO1041 Delete old spoolrequests. This abap used to be RSPO0041 in olderreleases

    RSTPTEST Tests the transporttool

    RSUSRxxx User related reports (000 list active users, 002 userby comlex criteria, etc)

    TOUCHALL Generate all ABAPs. Takes about 24 hours!

    1.5 Profileparameters

    rdisp/* gui-parameters

    rdisp/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 theOSS.

    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 userids. see OSS-note50088

    1.6.3 Userids on OS-level

    adm os-administrator for unix-activities as creating logical volumes,filegroups, smit, smitty, etc

    ora Oracle only: R/3-database administrator for SAPDBA-activities asbrarchive, sapdba-analyze, brrestore, etc.

  • 7/30/2019 Basis for Starters

    4/12

    SAPService 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 loggedon 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 its corresponding

    tracefile via button Show file. The default trace-level is 1. You can change thetracelevel via Process, Trace, Dispatcher, Change tracelevel (of all processes, not perprocess).

    2 Database

    2.1 General databaseknowledge

    Logging on to the database is done via:

    Log on as ora

    shows all systemtables

    sys.dba_role_privs; where grantee likeOPS$;

    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 execution

    v$datafile where status not in('SYSTEM','ONLINE')

    should be empty if SAP is online

    v$dba_rollback_segs Data of all rollback segments

    v$log; shows all logfiles (4) and which isactive

    v$logfile; shows all physical logfiles (mirrored,so: 8)

    The V$-files contain the dynamic performance tables which hold the runtime informationof R/3. To see all V$-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 ':\\' to ':\\';

    alter system switch logfile; (4 times to perform four logswitches)

    alter tablespace end backup; the tablespace will end its status of beingbacked up.

    2.1.1.3 SQL Other statements

    analyze table validate structure cascade;

    drop tablename from ??; deletes the table from the database.

    exit; logging out

    r3trans d v Tests if you can connect to the database

    r3trans l filename Checks if the file is consistent and correct and can be imported

    3.2 UNIX

    3.2.1 Simple commands

    chgrp grpfilelist

    Change the group that the file(s) belong to.

    chmod 777filelist

    Change the rights of the file(s). 777: owner-world-user. 7: read-write-delete (=111)

    ps ef |grepxxx

    Monitor processes with name containing xxx

    ps u

    4 General issues

    4.1 SAP Tools

    4.1.1 dpmon

    This tool allows you to check SAPs processes and to find out which one is killing theperformance. Especially useful when it is not possible anymore to log on to your system.

    (Oracle: use 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 transactionSMGW.

    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 database

    r3trans l Tests if the datafileis corrupt or not

  • 7/30/2019 Basis for Starters

    11/12

    4.1.6 sapdba, to be run as ora

    Sapdba is run to collect the data for the optimizer. This is done in two steps: FirstSAPDBA checkopt PSAP% checks which optimizerdata needs to be updated, thenSAPDBA analyze DBSTATCO gathers the data of the objects to be updated.

    sapdba analyze DBSTATCO Gathers the optimizerdata that needs to be updated

    sapdba check Checks the objects that you specify with itsparameters

    sapdba checkopt PSAP% Checks which optimizerdata needs to be updated

    sapdba 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 testpf=../../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 SAP

    saplicense show Shows the current license

    Request the license for the system by sending the fax included in the installation-kit toSAP.

    4.1.8 saprouter

    saprouter r R 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 canbe done with transaction STMS. Nevertheless the tp-commands are still be useful andneeded in some cases (yet). for detailed information on tp-command, see OSS-note309711.

    tp connect Tests the connection to tp locksys Lock the SAP-system for all users except SAP*

    tp unlocksys Unlock the SAP-system, giving access to all users

    tp showbuffer Show the buffer

    tp import 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.

    filesplit=yes|true|on(default=no)

    Export will be split into files of size 2147483647 (2GB-1). Usefulfor OSs that can not handle files larger then 2GB.
