Hi All

I don't know if this even possible, or what other options there might be, so feel free make any suggestions at all.

I have a customer who wants to take a snapshot of a set of libraries at a point in time each night. The obvious method is to save the libraries to save files and then restore them to different libraries, named appropriately, There are however a number of environments on this machine so space is something of a concern. If possible I would like to avoid recommending additional disk just for the purpose of save files, although I'm prepared to do this if it is the only practical solution.

What I have been toying with is whether I can manage to come up with a SNADS configuration that allows me to do a SAVRSTLIB onto the same machine. So far I have got as far as being able to pass through to the same machine, but not run a SAVRST* operation. To do this I got as far as creatin an APPC Controller of type *LOCAL and attached two APPC Devices that specify the other device as the remote system, however going the next step and getting a working APPN configuration has been beyond me. I also tried configuring the APC controller as an ANYNET controller ia the Loopback address without success.

A search of the IBM technical databases, the information center and Google has so far yielded me nothing but tantalising hints as to whether this is even doable or not.

I have considered alternative approaches using CRTDUPOBJ, however not all objects get duplicated (e.g. dataqueues) or using the cp command in Qshell (however this runs alphabetically and messes up logical files) but these approaches do not offer the documented safety of a save and restore approach. Having said that I haven't ruled them out - at this stage it's more because they don't work and may be marginally less predictable.

So, any suggestions as to what might be a viable alternative to just buying more disk ?

Evan Harris
