Hi,
After analysis of R3trans.log file i supposed you are using SSFS database connection method.Please correct me by providing more details on it.
4 ETW000 [ dev trc,00000] db_con_init called 34 0.000096
4 ETW000 [ dev trc,00000] set_use_ext_con_info(): rsdb/ssfs_connect not set => ssfs not used 40 0.000136
If yes/following SSFS connection method then try to set environment variable to force to use as connection method.
You can set it like below:
"setenv rsdb_ssfs_connect 1"
Also share db2diag.log file for further analysis.
Thanks,
Gaurav Rana
