In Replication Server 15.0, the rs_subcmp utility extends the maximum text and image size from 32KB to 2GB. You can specify the new value as length in kilobytes, doing either of:
Using the -L text_image_length_in_kilobytes parameter to set the new text and image length in kilobytes. For example, to set the new length to 64KB, enter:
rs_subcmp -L 64 -f subcmp.cfg
Providing the new value for text and image length to the parameter TXT_IMG_LEN in the configuration file. Start rs_subcmp using the modified configuration file:
rs_subcmp -f subcmp.cfg
subcmp.cfg file includes the following configuration parameter and its value:
TXT_IMG_LEN = 64
 If the value is specified both in the command line and
the configuration file, the value in the command line overwrites
the value in the configuration file.
If the value is specified both in the command line and
the configuration file, the value in the command line overwrites
the value in the configuration file.
