Hello,I have a question :
My host: Windows xp
My target: VxSim

I added BerkeleyDB22.wpj to my workspace and set a new build to SIMNTgnu,then I create my own project test.wpj building to SIMNTgnu.After that ,I downloaded them to vxSim successfully. when I spawn a task in WindSh like this :sp db_function

Errors come here:
__fop_file_setup: Retry limit (100) exceeded
ERROR:errno = 0x11
0x1cb92b8 (s1u0): 00 task is working
DB->put: method not permitted before handle's open method
0x1cb92b8 (s1u0): 01 task is working
ERROR:errno = 0x16
DB->get: method not permitted before handle's open method
ERROR:errno = 0x16
0x1cb92b8 (s1u0): 02 task is working
OK
0x1cb92b8 (s1u0): task is working

ret=dbp->close(dbp,0);
print_error(ret);


printf("OK\n");
logMsg("task is working\n",0,0,0,0,0,0);
}

Where is the problem?
Would you like to tell me a simple application like this ?
