TP RFC Connection Fails

[former_member182766]

Hi guys, yesterday I have updated Kernel and now struggling with the TP connection.

TP version - 380.18.68 (release 741, unicode enabled)

The RFC itself fails. Trace file from SMGW:

RSTPTEST:

Not sure what to do. Any help would be greatly appreciated.

It was an incorrect kernel patching procedure that caused it, so we had to quickly restore the pre-patching backup and try again, second time it worked

Hello Vadim,

could you please check KBA:

1872990 - various error messages related to incorrect resolution of localhost

https://service.sap.com/sap/support/notes/1872990

if it helps?

regards,
Alwina

[alwina_enns]

probably this line in dev_rd:

Full qualified hostname = localhost

is a problem. To which values the parameters SAPLOCALHOST and SAPLOCALHOSTFULL are set? Gateway gets "Full qualified hostname" from the SAPLOCALHOSTFULL parameter
