Dear Ana Cristina;
I never usedMIMIXreplication; but I hada similar experience withRocketiCluster; andbecausebothreplicatedobjectsthrough thejournals; I suggestreviewing thejournalconfiguration parameterwith the following command:
WRKJRNAJRN(R3SIDDATA/QSQJRN)
You mustvalidate that the"Minimizedataentry" parameter is set to*NONE, this parameteris usuallyset to*FILE
I hopeIwas able tohelp you.
Regards.
