This came as a shock to me. We just went to a basic sysplex, splitting a single image into two images. We just had a lockup occur between the two images. This was caused because SPFEDIT does a RESERVE on the volume during a save operation. OK, mea culpa, for not reading every word of all the manuals where it is mentioned. The problem came up due to a package called Data Accelerator, which does on-the-fly compression of VSAM and non-VSAM files. What appears to have happened is that a TSO user does a SAVE on one system. Coincidentally just a bit after this (I think) Data Accelerator on the other system attempts a RESERVE on its control file, which happens to be on the same volume. This "hangs" Data Accelerator on the second system. But, part of the SAVE operation on the first system invokes Data Accelerator to see if the file is compressed, requiring access to the control file which the second system has "hung up" on. Now both systems are hung up in Data Accelerator. This eventually hangs up every OPEN and CLOSE on both systems until I figure out what is going on (about 5 minutes once I'm informed of a problem).
The resolution: Put SPFEDIT in the conversion RNL. Also, put BMCBCSS in the reserve conversion RNL as well. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
