@PaulFox13 Thanks for the updates. We would like to visit Florida between the 31.07 and 06.08. Road trip from Orlando to Miami. We have no experience with the storms in Florida. What would you advise?

@heilja @martinberx @JLOracle This is possible. If you can figure out the correct values simply update the row. And if you want to access a row via a defect column you can do it with the hex value of the column: … where rawtohex(column) = 'hex'…

[Daniel Stein @Daniel_Wandern]

My next blog post will be about how it accidentally happens in your bank /insurance that a 0 byte is written into an #oracle 19c column and what highly problematic consequences that has depending on the column definition. @JLOracle you will love this one!

[Daniel Stein @Daniel_Wandern]

@martinberx @JLOracle Thanks for your kind words. The bug is first fixed in 23.1. 19c backport patches can be requested. Unfortunaly these patches can‘t fix the already corrupted data in your database…

[Daniel Stein @Daniel_Wandern]

A dangerous bug in Oracle 19c that allowed non-numeric bytes to be stored in number columns has finally been fixed after several years in the wild. Find out more about the issue and its impact on COBOL-based systems in my latest blog post. (Link in Bio) #oracle #COBOL #bugfix

Just published a new blog post on diagnosing and troubleshooting a crashing business process in a complex environment (AIX/LINUX/Windows) caused by a "#network problem" and "stealth #firewall". Check it out at https://t.co/yTDF6MGUoc

Java 11 is by default very reluctant to release unnecessary memory back to the operation system. The Shenandoah GC is more aggressive and is available in Java 11.

@ora600pl Thank you. Interesting article. We also had a lot of problems with flashback. At some point we let it go altogether.

[Daniel Stein @Daniel_Wandern]

I've been wanting to start a blog for a while. @TanelPoder gave me the final push I needed. Here is my first short post about his Index Helper Script : https://t.co/l90urup1bk The next post in the pipeline: troubleshooting a problem with the @windowsserver stealth firewall.

@TanelPoder Maybe DOAG 2023?

[Daniel Stein @Daniel_Wandern]

I stumbled across the script ash_index_helper https://t.co/vvvVCOCtNU

It really helped me get a Hibernate application under control that was way too slow. Thanks @TanelPoder

I'll never forget asking a guy who maintained 40yo mainframes for an insurance co why he didn't just migrate the apps.

His reply: the firm's actuarial code relies on specific bugs in the mainframe OS's floating-point handling. Run on any other system, it would produce chaos.

[Daniel Stein @Daniel_Wandern]

@oraclebase I think your website is excellent and it has helped me a lot. But I can't tell you how much I hate Oracle Flashback. It is an interesting feature but not suitable for production use. See my DOAG talks 2020 / 2021 on the subject.

@OracleSK @MikeDietrichDE @OracleSK Hervorragender Kundenservice, dass du soetwas für deine Kunden auch im Blick hast. Was würden wir ohne dich tun ? 😊

[Daniel Stein @Daniel_Wandern]

@OracleSK @MikeDietrichDE Thx. Ich leite es an unseren PatchDBA weiter.

[Daniel Stein @Daniel_Wandern]

Today we had a workshop hosted by @OracleSK on troubleshooting third-party software using Oracle as an example. He is a wizard. Fortunately more Gandalf than Saruman 😜
