APARs PJ40550 and PJ40702 complete the support for Online Database Reorganization (ODBR). We are now hearing from you about ODBR enhancements that you would like to see.
APAR PJ41031 allows a FCTB to be loaded by using ZODBR LOAD processing to move both data and specify format information (IFORMAT RAMFILs) in those areas where data was moved from.
Before APAR PJ41031, an additional online FCTB load (ZFCTB LOAD) had to be performed after the ODBR completed to load a FCTB with IFORMAT RAMFIL statements in areas that no longer contained data. PJ41031 saves you a step when using ODBR because you now can move data and then use the online formatter to format areas that data was moved from without having to use the ZFCTB LOAD command.
APAR PJ41087 improves the performance of the ZODBR LOAD command. During an ODBR load, a list of records is built to be moved. Also an I/O is issued to each track where the data is being moved, which verifies that the format of the track matches the size and duplication of the record moving to it. This process prevents I/O errors that result because of bad formats during the ODBR move process. Before APAR PJ41087, the verification of the track format was done by a single ECB which caused the track format verification process to take a long time if a large number of records were being moved.
With APAR PJ41087, you can control the number of ECBs used to verify track formats by entering the ZODBR PROFILE command with the STARTLVL parameter specified. The STARTLVL parameter specifies the number of ECBs that the system will use during the ODBR process.
APAR PJ41074 enhances the ZODBR DISPLAY STATUS message, providing the customer with a more accurate view of the ODBR move session. The first section of the display has been revised to include the status of the automatic and manual validation functions. The active move slot areas (MSA’s) from the ODBR processor unique keypoint has been expanded to include the active move slot number, the action being taken by that move slot, the addition of the current ordinal number being relocated, and the number of active ECBs associated with that move slot. Finally, the ZODBR DISPLAY STATUS message has been reformatted to improve the overall appearance.
