[Former Member]

Hi all,

I recently tried to copy the intranet's code of my firm on a new virtual machine, but after the php / saprfc installation, i got the following error :

Dear Romain

1) Configuration issue. The IP address or the port is incorrect.

2) The gateway on localhost with instance number 00 is not running.

3) Please check if you can reach the gateway from the operation system your j2ee engine is running on.

telnet 10.222.xx.29 sapgw00

telnet 10.222.xx.29 sapgw01

Which one of the above works?

Check in the transaction SMGW  - goto parameters display - then you

will see the parameters configured on your gateway host.

Thanks
