hi,

CAN any one reply what to do for this type of error?

[achim_hauck2]

yes

as the previous post already said: your server-name (ASHOST) value is wrong.

first: don't use the port here (:50300). You don't connect to the java-stack with jco but to the abap stack, here, either the dispatcher- (32xx) or the messageserver port (36xx) is used.

second: check, if you can ping the full qulified domain (gbdci550.in.ibm.com).

then, the connection should work.

kr, achim

if possible try the IP instead of the host name.
