ARPL | TPAMI 2021 ] Adversarial Reciprocal Points | Machine Learning library

Could anyone help with my datapump export. I've tried many combinations. But, I'm always getting:

We grant the following priviliges on schema A to user B for inserting into a queue in Oracle 12c:

I just bumped into some strange behaviour of DBMS_PARALLEL_EXECUTE (at least for me). See my preset (executed as SYS):

I’ve got a shellcode. It opens calculator in my buffer overflow program.

Little info, i have an arp.js file which takes a subnet address "192.168.2" and gets all strings returned from arp -a and stores in an array.

I can't figure out why my arpList function is returning an undefined value in my index.js file.

All the console.logs are returning the correct values in the arp.js page when called from the index.js, but the ipObj is coming up undefined. Even the console.log before i return of ipObj works.

Any help would be greatly appreciated.

I recently noticed an odd failure pattern recently in one database (12cR1) when using DBMS_REDEFINITION. CAN_REDEF_TABLE completes fine, as does START_REDEF_TABLE, but COPY_TABLE_DEPENDENTS fails with a bewildering:

ORA-01741: illegal zero-length identifier

After some debugging, the exception appears to be related to the ORIG_TABLE carrying both INVISIBLE column(s) and implicit system-named constraints. I'll include an example below to demonstrate the problem, but I hoped to gain some understanding of the behavior, and didn't see anything notable about INVISIBLE called out in the docs.

It seems there is some nuance to the creation of system-generated constraints I'd like to understand better. Apologies for the "why" question, but, Why do implicit system constraints behave any differently than explicitly-defined constraints during redefinition? I had thought that after being assigned a system-generated name, a constraint was just a constraint. Are system-generated objects different in other ways from client-named constraints beyond their names?

I also hoped to see if anyone has another workaround to recommend beyond just renaming implicit constraints or un-hiding the columns before the redifinition.

Thanks

Example: Below are three versions of the same ORIG_TABLE for redefinition. The first two both undergo the far-below redefinition ok with the given INT_TABLE, but the third throws the ORA-01741 during COPY_TABLE_DEPENDENTS.

Version 1: All columns visible, implicit system-generated constraints:

after upgrading our database system from 11g to 12c we cannot make https-requests to one of our webservers. After a lot of googling and trial-and-error we are pretty sure that error is due to our remote certificate. The wallet doesn't contain the server certificate, only the CAs are present (read this somewhere, ora12 doesn't like the regular certs in the wallet any longer)

The only special thing I found about our certificate:

It has no CN, it has only a couple of SAN specified.

With 11g the requests work like a charm, but 12c doesn't allow the certificate any more. We found out that utl_http_request() got a new parameter, "https_host" which is matched against the common name of the server certificate (1), not saying anything about the subject alternative name. No matter which value we choose for this parameter, the call fails with an ORA-24263.

I cannot understand why oracle should ignore the SAN, as they are a pretty mandatory as per RFC6125 (2) from 2011:

However, it is perfectly acceptable for the subject field to be empty, as long as the certificate contains a subject alternative name ("subjectAltName") extension that includes at least one subjectAltName entry, because [...]

Anyone having similar problems?

How to work around this error?

Thanks

As the title says, I need to store some big json files on a "blob" field on a oracle database. We've been using the "utl_raw.cast_to_raw" function, which seems to be the suggested way to do it, but we quickly hit the 2000 byte size cap.

I've been looking around for a solution, and the only one I've found points towards converting the Json to a byte array through a webservice (We are using Java instead of C#, but it shouldn't be an issue).

There's something else we can do to get our big jsons on the database without having to relay on a new development?

I have a Java application which connects to an Oracle database. One of the tables contains a blob column, which we populate using utl_raw.cast_to_raw, like this:
