Increase QNTC Buffer size to 32768 from current 16384

I would like to see QNTC directory access be made available to 32768 shares, which is double the current 16384. This is due to a buffer limitation in the QNTC code. It would involve essentially doubling the size of the available buffer.

Use Case:

We use NetApp to serve files.. several of the Servers in use and the one that has suddenly ceased to be available has close to 17000 shares hanging off it. Due to buffer limitations, we can no longer access this server. We have a reporting application that uses this access to funnel PDF reports from iSeries to various shares built off this NFS server.

    This is supported in IBM i 7.5.

    QNTC has been updated to allow listing 32768 shares.

    We understand the importance of being able to list more shares than 16384.

    The CAAC has reviewed this requirement and recommends that IBM view this as a medium priority requirement that should be addressed.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    Thank you for submitting this request. We understand this is a limitation and the development team is currently investigating it. The existing limitation is tied to a system limit in how QNTC is allocating the storage and we are investigating if the space can be managed differently.
