一个ER复制环境中，之前运行的好好的，突然报了错误"ER encountered a fatal error while evaluating replicate er_repl1 SQLCODE:-1213 ISAMCODE:0"，然后ER复制关闭，无法再启动。
-1213 A character to numeric conversion process failed.
A character value is being converted to numeric form for storage in a
numeric column or variable. However, the character string cannot be
interpreted as a number. It contains some characters other than white
space, digits, a sign, a decimal, or the letter e; or the parts are in
the wrong order, so the number cannot be deciphered.
If you are using NLS, the decimal character or thousands separator
might be wrong for your locale.
