Who needs Accenture in the age of AI? The self-styled reinvention powerhouse faces its toughest job yetβ€”remaking itself

The AI age looks likely to belong not to enablers of technology like Accenture but to its originators

Today is a special day for me: it is the last working day of 2025. I will do my best to spend the rest of the year doing whatever makes me and my dearest ones happyπŸ˜ƒ

The issue was due to the COLUMN TRANSFORM clause. According to my tests:
- COLUMN TRANSFORM is needed when NO offset/length is specified.
- COLUMN TRANSFORM is NOT needed when offset/length is specified.
Even though I don't understand why such an inconsistency exists, now I know how to implement it.

Utilities Learn from these examples how to use the ORACLE_LOADER, ORACLE_DATAPUMP,ORACLE_HDFS, ORACLE_HIVE access drivers, and to use external tables with vector data.

The non-working example provided in the documentation can be found in "Oracle Database Utilities Guide - 18.7.2.2 Loading LOBs from LOBFILE Files".

Excerpt of "Oracle Database Utilities Guide" describing how data is processed when the LLS clause is used.

Excerpt of "Oracle Database Utilities Guide" describing how data is processed when the LLS clause is used.

I'm looking for a working example of the LLS Clause in #OracleDatabase, but I'm unable to find it. Also the one provided in the doc is wrong (doesn't work).
When no offset/length is specified, it works as expected.
With offset/length, I always get a KUP-04001 error referencing an invalid file name.

Salesforce to acquire data management company Informatica in $8 billion deal Salesforce is buying cloud data management firm Informatica to bolster the enterprise software giant's push into artificial intelligence.

In other #databs news, Salesforce is buying Informatica. I guess Salesforce is where aging data tools go to die.

A "Kingdom of Clay," Beneath the Surface A guided tour around Roland Garros and its storied history, unearthing nearly a century of the best and the worst moments here.

To mark publication of my new book THE WARRIOR. I took a stroll with @benrothenberg.bsky.social. We visited landmarks I focus on in the book, which goes deep on #Nadal's career & #RolandGarros.

This unique post is a guided tour & audio tour. Thanks Ben!

#QlikConnect appreciation event took place in Disney's Animal Kingdom. I'm not a big fan of such parks, but it was fun. Avatar Flight is really impressive! Thanks to #Qlik and diamond sponsors #AWS and #Accenture.

First time I attended a conference using the silent-disco approach. E.g. on the photo, there are three "rooms" with parallel sessions. I must say it works really well.

Hey #Oracle, can you please remove from the 23 documentation references to Java classes (e.g. oracle.sql.STRUCT/OPAQUE/ARRAY/REF) that were deprecated more than one decade ago?

If it's related to wind, I guess that there are still plenty of electrical overhead lines. In CH, except for trains and HT, they are getting very rare...

According to Oracle Support it's bug 36628068 - HIGH CONTENTION ON SHARED POOL LATCH WHEN ALLOCATING FSO SCN FIELDS. Waiting on a backport to verify how good the patch works.

Somehow, I find it strange to see my name on a conference agenda... I can't even remember the last time it happened (except for #tvdpdays #rip). Anyway, I'm happy to talk about what we developed in the last 5 years.

On the customer's database, I have limited access. Hence, I only took a systemstate (level 266).
On my notebook, I used perf to confirm that what I see seems equivalent to the customer's database.
It seems that the issue is caused by kdlwiOpen1/kdlwiClose1.
Next, I will try the fix for bug 35999726.

To be clear, the contention is due to the 8 parallel processes themselves; not to other concurrent operations. The following images illustrate what I observe on my notebook when moving a small 1-million-row table...

I would love to know why in #OracleDatabase only statement #2 is subject to shared-pool latch contention. If you have a clue, thank you for sharing.

#2: ALTER TABLE t MOVE LOB (l) STORE AS SECUREFILE (COMPRESS) PARALLEL 8
