How NDS (Network Delivery Services) and NETQUEUE data set SAVE operand works

Issue/Introduction

What does the SAVE operand on the NETQUEUE initialization parameter do?

 

 

Resolution

The SAVE operand specifies the frequency at which NETQUEUE file saves occur.

The frequency is in seconds, and must be a value within the range  0(zero) to 30.

When seconds is a non-zero value, the NETQUEUE data set is saved every interval of those seconds.
At least one NETQUEUE update has to occur in the interval for the NETQUEUE data set to be saved.

When seconds indicate a 0 (zero) value, the NETQUEUE data set is saved every time a NETQUEUE update occurs.
The initial NETQUEUE data set save interval default value is 0.

 

Additional Information

ESP standard communication method:

Network Delivery Services (NDS) transfers ESP job tracking information between ESP master subsystems that exist on separate JES nodes, 
using standard TCP/IP protocol. 

NDS requires the NETQUEUE data set to store job tracking records when an NDS tracking service internodal transmit request is made. 
This occurs regardless of whether a connection between the local and remote ESP subsystems currently exists. When ESP on the remote 
node confirms receipt of an internodal job tracking record, the record is purged from the NETQUEUE data set.

LOADNET member is included in the Initialization Parameter.

Note: Create your NETQUEUE data set, using example member CYBESS01 from the sample library prefix.CD7YJCL
