This error can occur when a network firewall is severing the connection between the Eguide client application and the SAS Metadata server. Setting the KEEPALIVE option on the SAS Metadata server will help to prevent firewalls from disconnecting SAS Enterprise Guide client sessions.
The KEEPALIVE option can only be set within a configuration file for the SAS Metadata server.
1. Go to the directory where the Metadata Server's configuration files are located.
On a Windows machine, the location is:
\<SASconfig>\LevN\SASMeta\MetadataServer\
On a Unix based machine, the location is:
/<SASconfig>/LevN/SASMeta/MetadataServer/
2. Make a backup copy of the Metadata Server's "sasv9.cfg" file.
3. Modify the Metadata Server's "sasv9.cfg" file.
4. Look for the line that begins with this text:
-objectserverparms
5. On the -objectserverparms line, specify keepalive=value between two of the existing parameters
Note: value = the time in seconds you want the packet to be sent to your Firewall.
For example:
-objectserverparms "cel=credentials protocol=bridge port=8561 keepalive=600 classfactory=0217E202-B560-11DB-AD91-001083FF6836 trustsaspeer='Path\to\trustedPeers.xml' hostknownby='machinename'"
6. Close the sasv9.cfg file and save your changes
After both of these are set, you will need to stop and restart your Metadata Server and Object Spawner. If you have additional SAS services, you must stop and start all your SAS services in the correct order.
