OCI Direct Path Using Shared Connections?

Question

Hello there. A co-worker and I are working on developing a system using direct path. I designed it to follow the very basic direct path approach, and he suggested I try and share the database connection. I then wrote a class for sharing the connection, and everything seems to work fine until the OCIDirPathFinishLoad() is called. I get a 00600 code, which basically means some internal error code, and that I should contact Oracle about it. My question is whether I should be able to do two direct path loads using a single connection, or do I need to use multiple connections/multithread?
I'd appreciate responses to [email protected] Thank you!

Hi
Need ur help.
I am using OCI Direct path loads. It is working fine.
But when I try to do the parallel mode, it is not working.
For parallel mode, the only extra things that happens is:-
if (tblp->parallel_tbl) /* set table level parallel option */
OCI_CHECK(ctlp->errhp_ctl, OCI_HTYPE_ERROR, ociret, ctlp,
OCIAttrSet((dvoid *)dpctx, (ub4)OCI_HTYPE_DIRPATH_CTX,
(dvoid *)&tblp->parallel_tbl,
(ub4)0, (ub4)OCI_ATTR_DIRPATH_PARALLEL,
ctlp->errhp_ctl));
But when I do this, the following calls returns a zero value for "ctlp->nrow_ctl" (it returns a value > 0 when I dont do the parallel thing above)
/* get number of rows in the column array just allocated */
OCI_CHECK(ctlp->errhp_ctl, OCI_HTYPE_ERROR, ociret, ctlp,
OCIAttrGet((CONST dvoid *)(ctlp->dpca_ctl),
OCI_HTYPE_DIRPATH_COLUMN_ARRAY,
(dvoid *)(&ctlp->nrow_ctl), (ub4 *)0,
OCI_ATTR_NUM_ROWS, ctlp->errhp_ctl));
I'm using the sample code given by oracle, with minimal changes.
Thanks in advance
