You will want to check in the BSDS of the DB2 data sharing group (using offline utility DSNJU004) to determine if there is a STCK to LRSN Delta defined for the data sharing group. This delta is required when a DB2 subsystem is converted to data sharing with a (then) current log RBA that was greater then the high order 6 bytes of the STCK value. If this value is non-zero, it will need to be subtracted from the LRSN value prior to converting it to a timestamp field. ============================================== Wayne Driscoll OMEGAMON DB2 L3 Support/Development wdrisco(at)us(dot)ibm(dot)com All opinions are mine, and do not represent IBM Corporation. ==============================================
