Its really pays out - to click on all url's (just kidding) - as not regular vscode user, was not aware - documentation to plugins is on marketplace. Have already given up on diagrams - pressed Shift just not allow drag anything. Till i read NOTE: Hit 'Shift' button when cursor is over diagram πŸ˜€

quick test shows that at least KEEP doesn't raise any error by using it in identity column, so maybe it is just lack of documentation, but maybe ofcourse it is intention to prevent anomalies as you suggest

Never worked with proxmox - but run into similar issue with OEL 9 on vanilla qemu - the workaround/fix in my case was to use -cpu max. Maybe you can try this setting in qm.conf or similar...

In sqlcl wallet connection worked in the past either - just not out of the box, the connection string had to be extended by @jdbc:oracle:thin/oci - so, i wrote kilobytes of shell aliases/doskey macros to hide it. Now i can send them all to /dev/null. Am very sad about it (not really) 😘

It seems - 23.7 RU was the last one where _exadata_feature_on=true worked, 23.8 just ignores this hack. Otherwise, maybe it was removed shortly before release on premise for non engineered, who knows πŸ˜€

Didn’t plan on it, but sometimes the rabbit hole chooses you... Turns out "oradebug doc" doesn't expose all trace events.

just to mention one of alternatives
count(*) over(order by n rows between unbounded preceding and current row)

It's to be tested, i guess. I for myself will try to follow this method for a month and then compare, whether i feel better or not

on a serious note - recently read one doctor, who claims we can mostly compensate sunlight shortage even at winter season being at least 2 hours outside of office, also walking, whatever. Somehow feel in agreement with that

The only issue i discovered till yet - that i need to use the jdbc url (oci8 and thin - both are ok) - in case of wallet, without the jdbc url - no flags work (-thin, -thick, -oci) - but as i understood - bug is already filled for this issue, so i need only wait till it get fixed and released ;-)

Right, thanks, already figured it out, i was not aware of ojdbc.properties - have seen it by browsing sqlcl oracle forum, thanks for prompt hint and happy new year!

No, it just seems... using the jdbc url - like /@jdbc:oracle:oci8:@tns_alias does the job. Still a bit hacky( besides that - it tightly bound to the libocijdbc23.so version - the sqlcl.24.3.2.330.1718 requires (for oci connection) the instant client 23.5.0.24.07, thereas 23.6.0.24.10 is the current)

It seems, current sqlcl refuses to work with external secure store (oracle walet). Tried -oci flag, -thick flag, no flags at all (as stated in Doc ID 2987845.1 ) - get continuosly ORA-01017 (just vanilla oracle database, no cloud, no adb), whereas sqlplus works flawlessly

Query to obtain all firefox bookmarks from places.sqlite Query to obtain all firefox bookmarks from places.sqlite - bookmarks.sql

It drives me crazy to find a certain bookmark in firefox (have tons of them) - fortunately, it can be queried with sql

still the first question by oracle support if you fill a service request due to some error - is this behaviour reproducible in sqlplus 😜

Fun Oracle Database 19c error message fact: there are 7 ORA-xxxxx messages that say β€œDon’t do that”, 4 of them w/o an exclamation point, 3 of them do.

ORA-30658: attempt was made to create a temporary table with EXTERNAL organization

Cause: . . . This is not supported.

Action: Don’t do that!
