The star markd values need to be captured and i have used the function lrs_save_param("socket1", LRS_LAST_RECEIVED, "C_id2", 214, 3); to correlate the values. But its throughing en error.

lrs_save_param(socket1, get_last_received_buffer, C_id2, 214, 3)
Action.c(127): Error : save param parameter is invalid. Error code : 9005.

till the below part its bufferd
"\x01"

"\b"
"\x01"

from the below part its not bufferd

could you please let me know the way to proceed from this.
server database is 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production

Make sure that there is no other value which needs correlation before the occurecne of the value that you are correlating.
Try to use left and right boundary for correlation. For example:
lrs_save_searched_string("socket0", LRS_LAST_RECEIVED, "Parameter2", "LB/BIN= ", "RB/BIN=G", 9, 0, -1);
