Replication Server 15.7.1
improves memory utilization and support for large transactions in high-volume adaptive
replication (HVAR) and real-time loading (RTL).
The improvements include:
- SQT memory consumption control – you can control the maximum
memory consumed by unpacked commands in the DSI SQT cache during transaction
profiling in HVAR and RTL.
See:
- HVAR – SQT Memory Consumption Control for HVAR in the
Replication Server Administration Guide.
- RTL – SQT Memory Consumption Control for RTL in the
Replication Server Heterogeneous Replication
Guide.
- Net-change database size estimation and transaction profiling –
Replication Server does not mark a transaction as noncompilable even if the
transaction is larger than the DSI SQT cache size.
See Net-Change Database Size Estimation and Transaction
Profiling in the Replication Server
Administration Guide Volume 2.
- Full incremental compilation – Replication Server uses HVAR
mode, which is more efficient than continuous replication mode, to compile and
replicate large transactions.
See Full
Incremental Compilation for HVAR in the Replication Server Administration Guide Volume 2.
