DFSMShsm is an excellent use case for zEDC and is our number one best practice for HSM. When enabled, DSS zEDC compresses all blocks of data passed to HSM during Migration and Backup. Because HSM is processing fewer data blocks, both cpu and elapsed time are reduced. When going to ML1, the

Re: Anyone exploiting ZEDC?

My recommendation has always been to leave Db2/CICS's RLE compression of SMF data enabled even with zEDC compression of the data. 1) Less data will be sent to the zEDC compression engine, which will then process faster. I believe at one point I had an IBM chart that showed this. 2) The data

Re: How do one return a fullword binary to a C program from an assembler subroutine?

The reason behind this is: C passes arguments "by value", which means that int arguments like textlen are passed directly as values, not as addresses. You get the value 120 in the address list, pointed to by reg 1, not the address of textlen, which is different from COBOL or FORTRAN etc (COBOL
