Hi. it's true. After upgrade the my engine to solve some bugs my HDR (replication) stop. The index in secondary box will be corrupted and the replication stop. I don't know if ER (Enterprise replication) has the same problem. This bug don't will be solved in UC7. Now i'm planing to comeback to UC5 release or prior :-(((( --------------------------------------- Isidre PONS ROCA BASE - Gesti' d'Ingressos Locals (Diputacio de Tarragona) Servei de Sistemes de Informacio Av President Lluis Companys 12-C 43005 - Tarragona SPAIN Tel # +34 977 236731 Fax # +34 977 227302 http://www.altanet.org ipons@dtgna.altanet.org ---------------------------------------

I don't know if ER (Enterprise replication) has the same problem. No. The nature of the problem has to do with index btree treatment in recovery mode. ER does not 'recover' the index. HDR operates by always being in recovery mode. The problem was exposed by a performance issue encountered by some SAP customers that did a large update to an index and then bumped into a long transaction which rolled back. The patch to that problem B121385 was included in 7.31UC6. This patch exposed the regression, B129463. This appears to only be a problem in 7.31UC6. It does not appear in 9.x > > > This bug don't will be solved in UC7. > > Now i'm planing to comeback to UC5 release or prior :-(((( > > --------------------------------------- > Isidre PONS ROCA > BASE - Gestió d'Ingressos Locals > (Diputacio de Tarragona) > Servei de Sistemes de Informacio > Av President Lluis Companys 12-C > 43005 - Tarragona > SPAIN > Tel # +34 977 236731 > Fax # +34 977 227302 > http://www.altanet.org > ipons@dtgna.altanet.org > ---------------------------------------
