Sybase SQL remote 更改传输断点的方法

在sybase 的ASA与ASE数据库间通过SQL REMOTE传输数据经常会遇到传输日志点有误的现象.

一、通过翻译日志，并对照ASA、ASE的传输日志，确定正确的ASA发送点

1、在ASA中通过sa_setremoteuser存储过程，更改SYSREMOTEUSER表中的log_sent、confirm_sent字段，其它字段保留SYSREMOTEUSER表中的原值

2、如下为sa_setremoteuser函数及其参数：

sa_setremoteuser(p_user_id unsigned integer,p_log_sent numeric(20),p_confirm_sent numeric(20),p_send_count integer,p_resend_count integer,p_log_received numeric(20),p_confirm_received numeric(20),p_receive_count integer,p_rereceive_count integer)

3、sa_setremoteuser参数与表SYSREMOTEUSER字段值的对应关系

参数                                        字段
p_user_id                                  user_id
p_log_sent                                 log_sent
p_confirm_sent                             confirm_sent
p_send_count                               send_count
p_resend_count                             resend_count
p_log_received                             log_received
p_confirm_received                         confirm_received
p_receive_count                            receive_count
p_rereceive_count                          rereceive_count

4、ASA SYSREMOTEUSER表与ASE sr_remoteuser表的字段的对应关系，但两边的有些字段值并不会完全相等，例如：有可ASA中刚做数据传输，但ASE还没有做数据传输，此时ASA的log_sent可能大于ASE的log_received

     ASA SYSREMOTEUSER                   ASE sr_remoteuser

log_sent                                 log_received
confirm_sent                             confirm_received
send_count                               receive_count
resend_count                             rereceive_count
log_received                             log_sent
confirm_received                         confirm_sent
receive_count                            send_count
rereceive_count                          resend_count
