ORA-29013: SSL MAC verification failure
Answers
-
We have just upgraded from 19.8 to 19.10. We still have MAC verification error, but I'm not able to reproduce the "ORA-29263: HTTP protocol error" which we also got, looks like the same user8602157 describes, with responses bigger than 32K . At least I've not able to reproduce it after the upgrade to 19.10.
So - still working on the MAC verification error then :-/
-
We have been given OOB patch for 19.9 which from our initial testing appears to fix the issue of the corruption and don't get the MAC verification, but that part was intermittent. We did try 19.10 but still got the corruption. Planning to upgrade our development system to 19.9 and apply the OOB patch so the developers can do a more thorough test.
-
Oracle Support says "As this is not a generic issue from the database end we will not be able reproduce the issue.", meaning there are no errors with the database regarding this. If so, what is it then? Windows? The network? I'm so confused.....
-
problem is not on linux so far we had noticed, seems like windows with oracle together is some kinda problem...
-
Ok, thanks for feedback on that Janis :-)
-
The only information I currently have from Oracle support is "We found a not published BUG from Network team", I am waiting for more details from Oracle support. The patch itself only contains one main file which is oran19.dll. There are no scripts to run on the database afterwards.
-
ok, that's interesting user8602157. Please let ut know the outcome, and maybe the bugnumber if you have. Also if you can send me your SR-number in PM here, I can update my SR-case with that.
-
btw there is patch available for 19.9 and and 19.10 and it seems to work . Apply Patch 32738356
have a good day!
-
Yes, Janis, I got to know that from Oracle Support too, but we did not manage to apply it, as we got this in the log:
[2021-05-18 11:28:30] Error: prereq checks failed!
[2021-05-18 11:28:30] patch 32738356: XML descriptor does not exist in either the file system or SQL registry
[2021-05-18 11:28:30] Prereq check failed, exiting without installing any patches.
Do you happen to know what this is? (I have of course sent the log to Oracle Support, and awaiting their answer)
-
do you have 19.9 or 19.10 version of oracle db? to me all worked nice, only problems still with 19.11. so i rolled some test server back to 19.3 and applied 19.10 and then this patch .
