In SP302, three new parameters are added:
erssd_cache_size
Have you ever monitored the memory usage of
an ERSSD database server? It keeps growing
and gets bigger and bigger without limit. You
start to worry your replication server will not be
able to obtain enough memory from the
operating system and crash. Now SP302
provides a new server parameter
erssd_cache_size to limit the memory usage of
ERSSD server.
-ch size is a server option of SQL Anywhere
dbsrv16, setting the maximum cache size as a
limit to automatic cache growth. For example,
"-ch 30p" is to set 30% of the physical memory
as the limit.
Erssd_cache_size parameter specifies the
maximum percentage of physical memory that
the ERSSD cache can use. The default value is 0,
which is the default cache size that SQL
Anywhere uses. By default, the data cache of

2228385 - DSI connection to the DC/DB2
mainframe is down with ERROR #5095 on
rs_lastcommit table.
Since 1571 SP204, Replication Server started
supporting replication from SAP ASE into
Hortonworks® Data Platform (HDP®). HDP is
based on the open source Apache Hadoop Data
Platform. This article describes the software
download/installation, setup and key
configurations for the replication.

2220544 - Missing identity may cause DSI
down with Error 584 'Explicit value specified
for identity field in table'.
I like the workaround when there are a lot of
transactions in the outbound queue. The
solution is to alter replication definition to
declare the column as identity. When you alter
the replication definition, you must remember
to stop updating in the primary databases.

When you create a connection to Oracle
database via ECDA and the server checks out
REP_EC_ORA, which is for ECO (ExpressConnect
for Oracle), the problem is due to that the
connection is created using rs_xxxx_racle;eco or
set dsi_dataserver_make to 'ora' and set
dsi_connector_type to 'oci' in the connection.
By default, the server block_size is 16k. 1G

blocks. If the block size is doubled, the number
of segments of the partition will be reduced by
half. The article shows the segment number

State 1, Severity 1 -- 'Backup Server: 4.171.1.1:
The current value of 'reserved pages threshold'
