Hi Ibrahim,
Here issue is related with the below host name parameters set for the system
icm/host_name_full ibisky
Try to set it as
icm/host_name_full ibisky.workgroup.com
Host name is appearing two times as because of the parameters SAPLOCALHOSTFULL,SAPFQDN & SAPLOCALHOST.To set the correct value suggest you to follow
Setting the FQDN
The following variables and parameters are used to set the host and domain names:
● SAPLOCALHOST
● SAPLOCALHOSTFULL
● icm/host_name_full
The ICM sets the FQHN in accordance with the hierarchy below:
1. The SAPLOCALHOSTFULL parameter in the SAP profile (recommended for high availability configurations) has top priority. If it is set in the profile file, the ICM takes this as the FQHN value.
Note that the system default value of SAPLOCALHOSTFULL contains the host name without the domain, which is why the ICM ignores the system default.
2. If the parameter is not set, the value in icm/host_name_full is used.
Set the value iicm/host_name_full = $(SAPLOCALHOST).domain.ext.
This is particularly suitable for situations where multiple application servers are operating with one instance profile.
3. If this parameter is also not set, the ICM takes the FQHN of the operating system.
The SAPLOCALHOST parameter is not fully qualified and is not used by the ICM for services.
SAP recommends that you set either SAPLOCALHOSTFULL (for high availability configurations), or icm/host_name_full.
from SAP link Fully Qualified Domain Names (FQDN) - Developing, Configuring, and Adapting Applications - SAP Library
One more thing which i would recommend you to modify host file as like
127.0.0.1 localhost.localdomain localhost
<IP of server> <FQDN of System>
After that try to re-check and confirm .
Hope this will help you.
Regards,
