Uninstall Java/Portal , leave ABAP Stack

[Former Member]

Hi SDN,

I have installed BI 7.0 ABAP/JAVA. SR2. I would like to drop the JAVA stack, due to the portal not starting and the SAPJSF password not working. I have been through SDN and sap help and notes trying to get the connection to work. I want to keep the ABAP stack, and drop the JAVA stack and re-install. Is this possible and what tool set do I use. The unistall script is no longer supported. I am on Iseries I5 platform.

Thank you,

Cliff Tervo

If for any reason you are unable to uninstall from the Master CD you can follow the below mentioned manual method :

1. Drop the J2EE DB schema (the db schema for this one SAP SID) BE

VERY CAREFUL, do not drop the DB schema for another existing system or

the ABAP schema.

2. Remove folder "data" at:

/sapmnt/QO1/global/security/data

3. Remove folder "SDM" at:

/usr/sap/<sid>/<Central instance>/SDM

4. Remove folder "j2ee" at:

/usr/sap/<sid>/<Central instance>/j2ee

5. Revert CI instance profile to their original state (backup copies

should exist) # they should be in the state before the start of the JavaAdd In

6. Uninstall SCS using SAPinst

7. Restart ABAP

Which solution is correct?

Steps:

1. Stop the central services instance and all dialog instances of your SAP system.

2. Stop the J2EE Engine of the central instance

3. If lines beginning with j2ee/* appear, delete these lines from the default profile

4. If lines beginning with the following parameters appear, delete these lines

from the central instance profile and from all dialog instance profiles,

exe/j2ee =

exe/jlaunch =

rdisp/j2ee_start_control =

rdisp/j2ee_start =

rdisp/j2ee_timeout =

rdisp/j2ee_libpath =

rdisp/frfc_fallback =

jstartup/trimming_properties =

jstartup/instance_properties =

jstartup/protocol =

jstartup/vm/home =

jstartup/max_caches =

jstartup/release =

j2ee/dbdriver =

5. Delete the central services instance

Stop SAP, stop all the SAP Services, delete the start and instance profile of SCS instance. Delete /usr/sap/SID/SCS

6. Delete Oracle Java DB Schema,

Start sqlplus and connect to the database.

Enter:

sqlplus /nolog

SQLPLUS>connect / as sysdba

Enter the following command to delete the database objects of the database schema:

SQLPLUS> drop user SAP<SCHEMA_ID>DB cascade;

Enter the following command to get the file name of the corresponding data file in the file system:

SQLPLUS> select file_name from dba_data_files where tablespace_name = 'PSAP<SCHEMA_ID>DB';

Enter the following command to delete the tablespace of the database schema:

SQLPLUS> drop tablespace PSAP<SCHEMA_ID>DB including contents;

Delete the data file of tablespace PSAP<SCHEMA_ID>DB from the file system

7. Delete /usr/sap/<SAPSID>/DVEBMGS<xx>/SDM

and /usr/sap/<SAPSID>/DVEBMGS<xx>/j2ee.

Thats all!

For uninstalling the java engine you can use Insatllation Master CD. In the installation master you have the option of uninstallation but iam not shore there is option to select only java engine.please check it.
