Can't launch publish-subscribe example

Bruno HensherApr 21 2023 — edited Apr 22 2023

Good day, respective all!

I installed NoSQL Enterprise edition 22.3.35 under VirtualBox 7 (with Linux 8).

My topology is:

****************************************************************************************

store=kvstore numPartitions=10 sequence=14
zn: id=zn1 name=KVLite repFactor=1 type=PRIMARY allowArbiters=false masterAffinity=false

sn=[sn1] zn:[id=zn1 name=KVLite] oracle-21c-vagrant:5000 capacity=1 RUNNING
[rg1-rn1] RUNNING
single-op avg latency=0 ms multi-op avg latency=0 ms

numShards=1
shard=[rg1] num partitions=10
[rg1-rn1] sn=sn1

*******************************************************************************************

Ping results are:

Example source for calling publish-subscribe feature was compiled without errors.

But when launching it, I got:

What am I missing?

Any help would be very appreciated.

TIA,

My Oracle Cloud tenant, cloud account, and secure email have no issues. Why haven't I received my password reset email for Oracle Cloud? This is very strange, and our attempts have not been able to solve the problem. May I ask who I should turn to for help?

If your account is a paid one, open a Support ticket.

If it is a Free Tier then you will have to rely on help from the community. Most probable cause that you did not receive the password reset email is that your account has been stolen and the email has been changed.

Thank you for your reply!
But when I chatted with the online customer service, they told me that my Oracle Cloud tenant, account, and email were all fine. So, there shouldn't be a problem of theft.
I have a free account, but who can I contact on the forum? I can only post, but no one on the forum can view my account permissions, right. I am currently trying to reset MFA, I don't know if it works.
It's quite ridiculous that I have a free account and can't enjoy any services, but how can I become a paid user if I can't log in to my account.
