SAP ERP 6.0 or SAP ECC 6.0 or it might also called mySAP ERP 2005 was powered with some new transacion code. Some code are for Basis. Some tcode is created to simplified Basis work. One of tcode which I have found is DBACOCPIT.
DBACOCKPIT is new tcode but actually old ones since it actually only summarize some tcode and gather them on one screen. From DBACOCKPIT screen you can go to ST04 screen, DB02 screen, DB13 screen, and etc. You can get information and statistics of your database since database startup on ST04 screen. DB13 gave you access to database schedule activities such as database backup (whole, full, or incremental), archive log backup, database update statistic, database check, and etc. DB02 gave you information about current size of database, tablespace, critical tables and indexes, and etc.
Well, DBACOCKPIT is very useful tcode for Basis.
On my previous tutorial, you have already learned how to create new tablespace. I done it for this purpose. As you see, I already created PSAPIDS_REORG tablespace.
You can check it via DB02 tcode. Now, I want to reorg MSEG table. Right now, MSEG table is located on PSAPIDS tablespace. I check it by double click-in PSAPIDS from above screen. and write down MSEG on Object Name field like this.
Press the green check (v).
Here is information about MSEG table I get.
Now, open your MS-DOS prompt (coz I am using Windows based IDES server) and using [sid]adm user.
Type this command : >brspace -f tbreorg -t MSEG -m PSAPIDS_REORG
This command will reorg MSEG table and move it to PSAPIDS_REORG table.
Confirmation required to start reorganization process.
Table reorganization status starting.
Reorganization process has completed successfully.
To make sure that MSEG table has been moved to PSAPIDS_REORG tablespace, check again using DB02 tcode and check on PSAPIDS_REORG tablespace.
Now, you can see that MSEG table has been moved to PSAPIDS_REORG. You can start reorganize othe table. For your safety, use it on offline mode (no user access SAP server).
By default, SAP R3 4.7 has 6 tablespace. You can check them using tcode DB02. I already show you how to extend tablespace that already exist.
Now I want to show step by step adding new tablespace. I am going to use BRTOOLS, to add new tablespace. Open your MS-DOS prompt using user [sid]adm. Use ora[sid] user for your UNIX box.
To add new tablespace, choose option number 2 Space Management. Then ENTER.
Choose option number 2 to Create Tablespace. Then ENTER.
Enter option number 3 to propose tablespace name. Tablespace name must have prefix PSAPIDS (for my IDES box). Depend on your box. Here, I named it PSAPIDS_REORG (Coz I want to use it later for reorganization purpose).
After that, enter C then ENTER.
Tablespace creation is going to execute. You do not net to shutdown your SAP R3 nor Oracle DB to do this. You can do this online.
Additional information you need to supply such as datafile size, increment size, etc. Then type c to continue.
Tablespace creation is running. Wait for couple minutes.
Tablespace PSAPIDS_REORG has been created successfully. Type C to continue.
Back to Space Management menu. Next step, check the result using DB02 tcode.
You can see that tablespace PSAPIDS_REORG has been added in tablespace list.
Congratulations ! Now, you can continue your coffee break time :D…
I am glad that a lot of Basis visiting my blog, asking me about Basis activity, tips, etc. Based on comments and email about how to extend SAP R/3 tablespace, I try to post this little notes. On this little tutorial, I am using Windows based SAP R/3 and Oracle 9.2. You can do it on UNIX based. Of course using different user. When you using UNIX based R/3 system, you have to use ora[sid] user.
Login to your SAP R/3 DB instance Windows using [sid]adm user. Open your command prompt.
Type BRTOOLS to enter BRTOOLS menu.
Choose menu number 2 by typing 2 and then ENTER.
There are many menus on SPACE Management including Extend tablespace, Create tablespace, etc.
Type 1 to Extend tablespace. To get information about tablespace list, you can use DB02 on your SAPGUI screen. For this tutorial, I want to extend PSAPIDS tablespace.
Type c to continue this step.
On this screen, you can see information about last added tablespace including datafile size, datafile name, etc. I use default (datafile size about 2470 MB). Type C to continue.
If you want to add more datafile, you can specified now by typing y. Right now, I just want to add 1 datafile so I type c.
Extending tablespace process is running.
Tablespace PSAPIDS has been extended successfully. Type c to continue.
Back to BRTOOLS menus. Type 9 and ENTER to exit BRTOOLS program.
To check your new datafile has been added to your tablespace you can use DB02 and then press REFRESH button.
Now, you can extend your tablespace easily and have a nice day.
NB : You don’t need to shutdown your SAP R/3 system or Oracle DB to extend tablespace. You can do this online while your SAP R/3 system and Oracle DB running.
SAP R/3 are ERP software using large database. Usually commercial databases such Oracle, DB2, Informix is used as its database server. Mine using Oracle 188.8.131.52.
SAP tcode DB02 is use to check database size, tablespaces size, current statistic, checking freespace statistic, analyze detailed tablespace, checking missing indexes, and space critical objects. Actually, we can do more than that.
SAP R/3 installation created 6 tablespaces by default. Here are name of their tablespaces :
I am using SAP R/3 Enterprises 4.7 ext 200 version. It may be different if you are using old or new ones.
SAP R/3 data is saved on PSAP[SID] tablespace. So, we need to managed this tablespace carefully.
When you type DB02,
Press Space Statistic button to find out tablespace size and its growth. Tablespace’s growth can be seen daily, weekly, or monthly.
To check tablespace current size, just click Current Size button.
Click on PSAP[SID] tablespace and then, click Freespace Analysis.
If your PSAP[SID] tablespace size is reaching 95% level, you should consider increasing its size. You can use BRTOOLS to increase tablespace size. We’ll talk about BRTOOLS later.
