Load into util next to a reorg

As discussed in IDUG EMEA 2023 Praag, i gave a presentation about reorg a big table that took 8 days. If the table cant be accessed, a recover to that point would take 6 hours. So table created at front that can have the data already loaded until some millisecondshours before the "crash" by crossloader from IDAA of a proces that loads directly from log scan into this backup table (after its been loaded with the IC ). So when this is done the backup table can be used directly if the original table is in error. 

 

Why is this needed, new features on alter table are coming like from PBR to PBG and then from PBG to PBR, if this a petabytes loaded table we know this will take weeks.

If the software house and IBM can create such a program , would help clients to make the step to run such a long runner reorg.

    Hi Janet , sorry for the late reply, thats not exactly what I mean. If the table you are reorging, after the reorg not accesable or a page is corrupt, you need to load the whole table from the latest Image Copy + copying the log apply from the last copy 9 days earlier that takes 6 hours ( what we found out, check my IDUG presentation) that would means ( load the table is 4 hour happy flow + 6 hours logapply ) is 10 hours offline...
    What we think should be a nice feature ..if we already copied the IC to a backup table (via redirected recovery) + and do the logapply per day (a certain timeframe) to that backup table..then you can do very quickly a rename of corrupt table, rename the backup table , do some binds of the packages that needs this table and you are 'directly' up andd running agian.

    Think that the table is a 'always on' table , every hick up is too much ..than is a solution via a redirected table + extra features the only way to go

    Dear Leo, Thank you for submitting this enhancement request.

    COPY SHRLEVEL CHANGE and REORG SHRLEVEL CHANGE can be run concurrently on the same target table space, except for the brief window in the LOG/SWITCH phase of REORG when the utility needs to acquire exclusive control. So even if the REORG runs for a week, image copies can be created on a daily basis or at the required frequency to meet the RPO. A later APAR PH11255 also supports LOAD SHRLEVEL CHANGE and REORG SHRLEVEL CHANGE concurrency if there's a need to load into the same target table while REORG is running.

    We appreciate your input to the Db2 for z/OS development team. And we hope that you will continue to submit enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS.


    Sincerely,

    Db2 Utilities team
