Who did you speak with at CA? -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of ??? ?? ??? Sent: Monday, February 04, 2008 SYSN 09:38 PM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: CA ESD files
Hi, I spoke with someone at CA yesterday, and they said that within the next couple of months, CA will replace the ESD files with something else. Now we just have to see what they replace it with.

This gets discussed from time to time. The answer seems to be that there is no supported (i.e. from CA) program to do what you want. However you could write your own program to read the ESD file, and split out the file(s) you want. The format is, of course, undocumented, but as a quick browse would show you, it's clearly not rocket science to parse out the headers. The ESD files are conceptually like an AWS file, i.e. they represent an entire tape, rather than a dataset. So there is a volume header, and a file header for each file. There is also some kind of basic run-length compression. Best bet is to submit a requirement to CA. I've often enough wanted to restore just one file from one of their tapes, and having to use a physical tape for this is ridiculous. Or maybe one of the virtual tape vendors, or the MFNetDisk guy could make it happen without a real tape.
