Changing Database User Passwords in an SAP System


Changing DB user's passwords using SQL commands is not advisable in some cases. The DB user's passwords are encrypted and stored in SAP tables or files which need to be updated with the new password. If you are using any custom script with passwords hardcoded, you will have to update them as well.

1. Changing DB Password for sapr3, sap<sid>, sap<xyz> or sapsr3

The passwords for DB users used by the ABAP engine are stored in the table SAPUSER. When the password is changed, the change must reflect in the table. To ensure that this is consistently done, use BR Tools:
brconnect -f chpass -o [sapr3 | sap<sid> | sap<xyz> | sapsr3] -p <new_password>
If the password changed using SQL command, the work processes, R3trans, saplicense etc will show error with return code ORA-01017.

2. Changing DB Password for sap<sid>db, sap<xyz>db or sap<sr3>db

The passwords for DB users used by J2EE engine are stored in the file /usr/sap/<SID>/SYS/global/security/data/SecStore.properties. The contents of this file are encrypted and can only be changed using config tool.

To change the password
1. Start the config tool
2. Select secure store
3. Open another command prompt and change the password using BR Tools
brconnect -f chpass -o [ sap<sid>db | sap<xyz>db | sapsr3db] -p <new_password>
4. Go back to config tool and update the password against the parameter jdbc/pool/<SID>/Password

It is advised that the passwords be changed with SAP applications stopped.

OS/DB Migration - CMD. STR, TOC, EXT, R3load, DDLDBS.TPL and more

Image
With increasing need to improve performance or reduce costs or vanishing support for operating systems/databases it becomes inevitable to migrate to a better OS or DB. We feel take a quick look at the primary ingredients of the tools for OS/DB migration handled by R3SETUP. Tools - R3load, R3ldctl and R3szchk R3ldctl creates STRucture files, TemPLate files by reading the technical settings for table/indexes in SAP data dictionary. R3szchk calculates the database size object sizes (EXTent files) for the target system based on the STR files created by R3ldctl. The EXT and STR files can be later split into smaller groups. The most crucial tool R3load is responsible for unloading and loading data from the database. R3load uses the files created by R3ldctl and R3szchk and dumps the data into compressed binary format as .001, .002 .. files. It uses cmd files to achieve the task. If the cmd files are not present, it creates on its own. Files Command files*.cmd  are created i

Fixing Inconsistent Table - Table activation fails due to inconsistency between DD and DB

If you find a table to be available on the database, but not active in ABAP dictionary, try calling SE14 as DDIC user, enter the table name and choose Table > Reconstruct, Execute. If this method fails follow these steps: Call transaction code SE37 and execute the function module  DD_TABL_ACTM with single test On the next screen, do not change any other field except the following and set them as shown below: MODE: 12 NTAB_PUTSTATE: N TABNAME: <enter the correct table name> Click on Execute The export parameter ACT_RESULT should show 0. To verify if the inconsistency is fixed, call transaction SE14 > Extras > Database Object > Check and  SE14 > Extras > Runtime object > Check.

301 Redirect Using SAP Web Dispatcher

301 redirects are typically used to redirect accesses that include www to non-www or vice-versa. Example, when you call http://blogger.com, the call is redirected to www.blogger.com. An end-user may prefer to call a URL in any manner. You must ensure that all these calls are redirected to relevant URLs with content. SAP web dispatcher can be configured to send a redirect (301) to the client. To enable redirection add icm/HTTP/redirect_<xx> to the web dispatcher's profile file. The parameter uses the following syntax: icm/HTTP/redirect_<xx> = PREFIX=<URL prefix>[, FROM=<pattern for URL>, FROMPROT=<incoming protocol>, FOR=<pattern for host name:port>,TO=<new URL prefix>, PROT=<protocol>, HOST=<host>, PORT=<port number/name>] Let's say you want to redirect all the HTTP requests on mysource.com on 80 port to mytarget.com on HTTPS 443 port icm/HTTP/redirect_0 = PREFIX=/, FROM=*, FROMPROT=http, FOR=mysource.com:80,
