Problem: An attempt to connect to AcuServer times out, or your application gets a time-out error during execution.
A typical time-out error message looks like:
File error 9D,14 on @condor:/usr2/bsmith/fio_seq.dat condor: Timed out
Time-out errors occur when: the server is down, the server crashes while your program is running, or network conditions produce very protracted response times (the result of an overburdened network, or faulty network hardware/software).
The diagnostic steps are:
1. confirm that the server machine is running and responding to the network
2. confirm that acuserve is running on the server
3. increase the DEFAULT-TIMEOUT runtime configuration variable to give the client/server pair more time to establish a connection
4. consult with your network system administrator and Acucorp Technical Support.
Diagnostics:
1. Confirm that the server is up and responding to the network.
From your client system use "ping" to query the server:
ping hostname
Ping will return:
hostname is alive
or
no answer from hostname
If there is no answer from the server, determine the cause of the failure (machine down; network connection faulty) and restore the server. With "ping", confirm that the network connection is working.
2. Confirm that acuserve is running on the server. On the server enter:
acuserve -info
If acuserve is running, the command will return a summary of AcuServer's current status. For example:
0 file(s) in use by acuserve on: hostname
If acuserve is not running the command will return:
acuserve is not running on hostname
If acuserve is not running, start acuserve and repeat the "acuserve -info" test.
Once acuserve is running, rerun your application on the client. If the connection still times out, proceed to step three.
3. Set the runtime configuration variable DEFAULT-TIME-OUT to 100 seconds (four times the default value) and run your application.
If the connection succeeds, analyze your network for the cause of the prolonged connection time. You should investigate network capacity, collision and retransmission rates, and network hardware or software malfunction.
If necessary, repair your network and confirm its proper operation. Reset DEFAULT-TIME-OUT to its default setting of 25 seconds and rerun your application.
4. If the application times out, you will probably need to work with your network system administrator, network hardware and software vendors, and Acucorp Technical Support to resolve the problem.
