I've found it to be at least 4 time slower in comparison to Info-ZIP. Not sure how bzip2 verion 1.0.5 compares to Info-ZIP? > I suggest this because I've no idea when I'll be able to fix the unzip patch. I don't require the MVS unzip (cmsmvs version) as urgently as I required the zip function. For now your USS unzip patch works well (& fast as well) with Kirk's CoZBATCH utility. I'm able to at least write to an MVS dataset, with the zip file residing in USS. On the topic of ZIP (MVS/cmsmvs version): ======================================== I've received feedback that all the zipped files using Info-ZIP were readable by the application. Except the following two issues : 1. Only problem experienced was that mentioned in my previous note of having to specify -fz option for zipping files > 7GB. I thought this was resolved. 2. Also for zipping a 46GB file (with the -fz specified) I get the following error : zip I/O error: EDC5013I No hiperspace blocks are available for expansion. zip error: Output file write failure (write error on zip file) I tried specifying MEMLIMIT=NOLIMIT in the JCL, but gives the same error. It looks to be that we've reached our limit on hiperspace blocks (Address space reaches 2GB when it ends with RC=14 and the above mentioned error). Not sure where/how to specify more.
