Hi Rableen,

RFC's can be disabled by using the Database level SQL update statement.

To lock :

update <SCHEMA>.rfcdes set rfcoptions = replace(rfcoptions, 'H=', 'H=#') where rfctype = '3' and  rfcdest not in ('<SID>') and rfcdest not in ('SIDCLNT200');

commit;

To unlock :

update <SCHEMA>.rfcdes set rfcoptions = replace(rfcoptions, 'H=#', 'H=') where rfctype = '3' and  rfcdest not in ('<SID>') and rfcdest not in ('SIDCLNT200');

commit;

PS : The above command will lock only the rfc type '3' (i.e. abap connections), which are sufficient for system refresh.

Incase you want to lock the tcp/ip connections use rfctype as 'T'

Hi,

Check tns.ora and listner.ora if it is pointing to the right server/IP.

To avoid issues I would suggest You clear all entries in sm59. All the required entries will be created when u start the system.

Login to sqlplus and truncate table SAPSR3.RFCDES;

commit;

select count(*) from from SAPSR3.RFCDES;

It should be 0.

After you start the system login and  run btctrns1 via se38 to deschedule background jobs so you will not be have make the BTC process zero.
