Re: my free mainframe product
Hi, Right now I start to distrbute MFNetDisk and I hope people like it. I really do not think now about price and money since I enjoy to let the people about my product. I specify 3 devices because I want the people to play with my product and understand its features. This product is more complicate then to try to explain the number of TCP session handle by the product, But each task in the MVS MFNetDisk have a open connection with IP and with its PC mirrors. The number of the tasks are specify in MVS side. I start to play with my site few months ago (6 months) but it start to be active 2 months ago. Most of the visitor start to visit before 30 days or so. This product it is new and I still working hard to have a new version with better and more features. I also will start to work hard with my documents which have a little information and the product have a lot more of data to be described. All the MF RACF are supported by this product. APF and free...OK , I want that everyone in MF will know about my product. The best way which I know to make them so is to ask them to play and use it for free. SVC..Normal run do not use SVC at all but need to recheck.. Thanks for wish me luck with this product but really right now I want that everyone will know and eventually use my product.

Re: my free mainframe product
Hi, My MFNetDisk product is active by users and they start to find bugs (that life). I put in my site in the download page a new MVS load library (The MVS side is version 10 ) which fix some critical bugs. Anyone which run my product must download the new load library and run with it. No cold start require for the new load library. Some tips for MFNetDisk MVS side: You can see all the modify command in MVS using the "F mpc010r,HELP command". The most MVS modify command I use are : F mpc010r,ip=q/r(Q or R) for query and retry. F mpc010r,conf=Q/NEW for query what are defined in MFNetDisk or change the MFNetDisk configuration dynamically. F mpc010r,SRV=Q (to check how MFNetDisk doing with tasks and pending requests.

Re: my free mainframe product
HI, Thanks for your good question. As far I know Hercules can not make mirrors to real 3390 and can not backup real 3390 and can not emulate 3390 from real MF or from any emulation MF as I do and can not be used for real DR purpose. MFNetdisk can run on real MF and can work with real 3390 disk (IBM, EMC or HDS) but of course it can run under Hercules or under any MF emulations. Easily the product can also copy and sharing MFNetDisk emulated 3390 between Hercules and real MF and any emulated MF. Yes, you hear good you can share MFNetDisk emulated 3390 between any MF (Hercules, IBM etc...) and the MFNetDisk keep the data integrity as real 3390 keep data integrity when it is shared between real MF. please try the program and you will see that this product is totally different from Hercules. I love what Hercules does but this is a different product. The only feature which is the same as Hercules is the data location of the emulated 3390 disk which is in PC. I can promise you that if and when you try the product you will love it. I know that we the old MF people afraid to try PC in MF environment but this product is different.

Re: my free mainframe product
I've been reading the notes for MFNETDISK for a while and it complements Hercules emulated disk as one of the functions. Unless I'm mistaken, the disk emulation would be useful where the disk is remotely located from the processor complex or emulated processor (Hercules etc.). Obviously performance would suffer depending on the available bandwidth for remote TCPIP transmission of IO but for an absolute DR capability, the product has many facets I can visualise. If a mainframe complex was taken out, the mirrored emulated disk could be distibruted across multiple locations on multiple PCs or just a single remote location. It might take some time to get your disk "re-assembled" into usable status but it would mean you have a fairly hot backup available ay any point in time. The product isn't actually much use on Hercules other than to test the functionality. To my knowledge, nobody is running modern o/s or TCPIP on Hercules since they can't be licensed. I don't believe there is a TCPIP for MVS 3.8, but I could be wrong here. Nice job, Shai. I hope you get some traction in the mainstream market.

The network speed will not be faster than your your slowest link. The mainframe is about doing thousands of things per minute, NFS works because it was not trying to handle the same workload as the mainframe. I suppose if I care about speed then I must run my own intra-net wiring where I can control the traffic on the wiring. The minute I use the inter-net, I am subject to routing beyond my control.

Sounds like you have a niche product for the home hobbyist, like Hercules. Hercules on a PC is not expected to handle millions of credit card transactions per day. NFS on the mainframe gives access to a network file, there is no claim you will get performance above what the slowest can give. Therefore, time sensitive transactions do not store their data on NFS disk files. Those shops who are looking to have 'instant' disaster recovery already need speed, reliability, and support.

Re: my free mainframe product
HI, > You know many people who backup PC hard drives? To what? And some kind of synchronized backup so when multiple restores need to be done the application still works. I can restore multiple backups in the same time. using Multi threading. The data can be in the net or in the same Hard disk. MFNetDisk manage all the backup. MFNetDisk have catalog of all the backups for each MVS device. >TCP is a protocol, how do you make it faster? Can you make English faster?

But if a company need to share disk in the net and to use all the nice (you said) features of my product and to be aware that the speed will be slower then the Ficon, then it is OK with me. Also my product make net mirroring, all the company which use net mirroring will have bad performance, That is a fact. Net line is a slower media then local line. >Sounds like you have a niche product for the home hobbyist, like Hercules. Hercules on a PC is not expected to handle millions of credit card transactions per day. NFS on the mainframe gives access to a network file, there is no claim you will get performance above what the slowest can give. Therefore, time sensitive transactions do not store their data on NFS disk files. I never claim that my 3390 will replace the local 3390 disks. My product can work good with Hercules and real MF as well. Right now not to process million of DB2 transactions but to be able o let the user recover the data quickly even if the performance will not be the same as real local 3390. >Those shops who are looking to have 'instant' disaster recovery already need speed, reliability, and support. I can give immediately access to their data in the speed of the TCP/IP and everything depend on how the TCP is configure and the hardware they use for the TCP. And yes, the TCP in MF was very slow because IBM use the TCP as software which use the SNA etc. and that why the IBM TCP was bad. But is become better and better and faster. IBM claim that they like to be big server and I ask you how they going to do it without TCP in open system. You think that they can force everyone to use Ficon? Can you imagine that MS and Lynux will change their local disk to Ficon? TCP in MF is faster then ever and i know that IBM understand that. >What happens to the application when those PC's and their drives start failing? Please install my product and try it, and at least try to read my documentation you will see that PC can mirror another PC and have backup data there. My product is a great solution to Medium and small sites at least at the beginning. And I can assure you that also big company will or already use my product for the backups, for replace real 3390 with another real 3390, for DR and for remote sharing disk. The emulation 3390 feature can be used for the restored 3390 which will allow you to access the data immediately. Easily I can buy Ficon card fro bustech and create the speed of Ficon but I want my product to use net and be the only one who give to MF what my product bring. And please try my product in MF and let everyone know about your experience.

Re: my free mainframe product and question?
More fixes to my product. Please download the new installation files in my site www.mfnetdisk.com Some people ask me about how much cost the product? I really do not know right now. In general I am not sure if I take money for this product in the future. If one day big company like IBM or EMC or HDS or what ever company like to buy my product then that is OK with me but now just play with my product. Please let me know what the product need to become more attractive. If someone want to have access to more devices for free please let me know. I like also to open discussion about is it acceptable for MF customers that MF data will be accessed with TCP and be stored in PC?
