But my choice may have been abad one now IBM has decided to not support the TSM Server on z/OS any more. The advantages of z/OS are many for us especially as far as DR goes. My second choice was FDR's product though. Back then a number of things bothered me about their implementation. 1. The pricing was on the amount of data to be stored. This causes one in the government to have to over buy to make sure you do not suddenly run out. 2. The storage of files on tapes had to be really thought though because of mixed expiration of data. The tape had to be kept around until the last bit of data on the tape expired. There was no way to take 2 or more tapes and pull all the non-expired data off to make one new one. This presented a challenge. 3. On had to keep track of what was on what tape in the case of what was current. It was not going to as straight forward as the model TSM has which is very much akin to HSM for Open Systems. I have told IBM people who are running TSM for z/OS are not going to suddenly switch it over and host TSM on Windows, etc, because of the various operational issues, etc and also losing the notion of leveraging existing ATLs, VTS's, Automated Operations, skill sets, Automated Scheduling, etc. But they contend that they can get DB2 to perform very well on z/OS to handle the TSM database therefore it should not be hosted any more on z/OS. I will be taking a 2nd look at FDR/Upstream to learn if it is any easier to keep track of files on all those tapes and also about pricing models. Oh yes, am told TSM for z/OS will be around stabilized at V5 and supported until around 2013. So folks should be making other plans long before they pull the plug. jim ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
