OCI Process hanging problem

Question

I'm writing some code run with oracle oci.
My Environments are like these
OS : Red Hat Enterprise Linux AS release 3 (Taroon)
DB : Oracle 10g(10.1.0.3)
Language : C(not Pro C/C++)(gcc)
Programing Steps are like below
1. Generating DB Connection(OCIInitialize thru OCILogon)
OCIInitialize((ub4)(OCI_DEFAULT | OCI_OBJECT), NULL, NULL, NULL);
OCIEnvInit(&phEnv, OCI_DEFAULT, 0, NULL);
OCIHandleAlloc((dvoid *)phEnv, (dvoid **)&phError, OCI_HTYPE_ERROR, 0, NULL);
OCILogon(phEnv, phError, &phSvc, username, strlen(username), password, strlen(password), database, strlen(database));
2. First file open
fd1 = fopen("file1", "r");
3. Second file open
fd2 = fopen("file2", "w");
4. Try read for file descriptio fd1
fgets(buffer, sizeof(buffer), fd1);
at last step(fgets), the process never return from system call read(), just consuming CPU.
If I don't connect with DB, the process is running well.
And these code are running well under Solaris8(sparc) and Oracle 10g environments.
what is problem?
Help me please...

Answer 1

Here are a few things to try.
1. Use OCIEnvCreate instead of envInit/
2. on ERR handle allocation.. Send it in a tmp address pointer to a void and allocate 52 bytes... (see demo code).
3. To logon use OCILogon2
Good luck,
