For SQL Server 2000 SP4 Transactional Replication Iâ€™m using continuous transactional replication on a database with 780 tables for a total of 133GB. It is being replicated to a reporting server. Some columns on a couple of the tables needed to be increased. Iâ€™m not very savvy regarding replication. I donâ€™t know how to make those changes without stopping replication. So, I stopped replication, deleted the subscription & removed the tables from the publication. Once the table changes were made, I added the tables back into the publication, re-pushed a subscription and started the snapshot agent. The snapshot agent kept blowing up with: I/O error while writing BCP data-file (Source: ODBC SQL Server Driver (ODBC); Error number: 0) I checked my snapshot location. It has 298GB free. I upped my BCPBatchSize to 500000. My QueryTimeout is 3000. MaxBCPThreads is 4. So, I have two issues:1.) What can I do to get my snapshot to run? I HAVE to have this working by Friday morning.2.) How could I have made the table changes without stopping the replication?
