How Is Signature Checking Better Than The Time-stamped Checking? |
|
Answer» Signature checking eliminates the problem of unnecessary recompilation of the program units ACROSS networks. The signature of the REMOTE procedure is stored in the p-code of the local procedure. In signature checking, the signature of the remote procedure is compared and not the time stamp. If the remote program is MODIFIED and recompiled but its signature does not change, then the local procedure can be executed without any runtime error. Therefore, signature checking does not degrade the SYSTEM performance by repetitive compilation of the local procedure.
