Replication modes and actions depend on the values you set for memory control parameters.
Replication Server processes noncompilable transactions in continous log order mode.
Examples that show Replication Server applying a transaction with 100,000 updates on two tables. Table1 has 100 columns and requires approximately 4GB of memory, and Table2 has 10 columns requiring approximately one-tenth the memory—400MB.
dsi_cdb_max_size Value (MB) | Table Name | Impact on Replication Processing |
---|---|---|
1024 (default) | Table1 | Replication Server applies the transaction in continuous log-order replication mode. |
1024 (default) | Table2 | Prerequisite: Set memory_limit in Replication Server to a value large enough to allow the construction of 400MB net-change databases. Replication Server applies the transaction using HVAR. |
4096 | Table1 | Replication Server applies the transaction using continuous log order replication mode. |
4096 | Table2 | Prerequisite: Set memory_limit in Replication Server to a value large enough to allow the construction of 400MB net-change databases. Replication Server applies the transaction using HVAR. |
