If the character set change involves a change of character width, reload the stored procedure messages of all databases controlled by the Replication Server.
The stored procedure messages are in $SYBASE/$SYBASE_REP/scripts/rsspmsg1.sql and rsspmsg2.sql for UNIX, and %SYBASE%\%SYBASE_REP%\scripts\rsspmsg1.sql and rsspmsg2.sql for Windows.
For UNIX
isql -Uuser_name -Ppassword -Srssd_name -Jeucjis < $SYBASE/$SYBASE_REP/scripts/rsspmsg2.sql
isql -Uuser_name -Ppassword -Srssd_name -Jiso_1 < $SYBASE/$SYBASE_REP/scripts/rsspmsg1.sql
For Windows
isql -Uuser_name -Ppassword -Srssd_name -Jeucjis < %SYBASE%\%SYBASE_REP%\scripts\rsspmsg2.sql
isql -Uuser_name -Ppassword -Srssd_name -Jiso_1 < %SYBASE%\%SYBASE_REP%\scripts\rsspmsg1.sql
When the change is to the UTF-8 character set, install both rsspmsg1.sql and rsspmsg2.sql
