I am using volt db community edition and I am creating the tables in volt db database. Once I restart the server all tables stored in database are deleted. How to save the tables permanently in volt db database using command line?
VoltDB Community Edition does not include any durability features. Those are found in the Enterprise and Pro editions, available at voltdb.com.
Disclaimer: I work for VoltDB.
Just shutdown the server with the command:
voltadmin shutdown --save
This will create a snapshot that the system use to restore the database on restart. I am also using the community edition, I have tried it and seems to work. Hope it's still useful :)
References are here: Official Documentation

We have a situation where we want to re-seed the edge offline database from a checkpoint of the live DB. I understand there will be downtime as a dump of the online edge database will have to be performed.
Can someone help me with the commands "how to dump the database/tables" and "how to restore the offline database from the dumped file"?
FYI-- We are runing SDP 2017 version

So i am trying to monitor oracle database replication using zabbix,
my setup is:
oracle database 11g r2
zabbix 5.4
i did install ODBC client in zabbix server and follow this step, my zabbix server can connect with my oracle database via ODBC. But, when i add template 'Oracle Database by ODBC' i got this error:
i already set host macros, here's the configuration:
i turn off firewall, disable selinux, but it's still can fetch data from my database..
can someone help me? or maybe now zabbix doesn't support monitoring oracle database 11g?
thank you
This setup does not support oracle 11. I am pretty sure the template could be adjusted for that but you do need some oracle and zabbix knowledge to get that working.
Years ago I created https://github.com/ikzelf/zbxdb and that does support about each and every release I could find. It is quite a different setup but it also supports more advanced oracle configurations. Maybe it can help you.
In [MemSQL documentation FAQ page][1]
[1]: https://docs.memsql.com/v7.0/introduction/faqs/memsql-faq/, it says:
MemSQL reports the version engine variable as 5.5.8. Client drivers look for this version to determine how to interact with the server.
This is understandable, but an unfortunate side effect of this is MemSQL fails the security scan tests by security team and brings up a lots of red flags. In the same page, MemSQL says MemSQL is not necessary impacted by any of MySQL found security vulnerabilities:
The MemSQL and MySQL servers are separate database engines which do not share any code, so security issues in the MySQL server are not applicable to MemSQL.
But red flags are red flags, so I wonder if this reported version is user adjustable so that we can calm the security scan test? But also want to know what are known impacts that could be caused by changes of the reported version of this.
Yes, the "Mysql compatibility" version can be changed via the compat_version global variable. You should set it to the version string you want returned via select ##version (i.e., '8.0.20'). Keep in mind now and then client drivers and mysql applications check this version to enable\disable features so you need to test out the impact of the change on your applications.
I installed oracle 11g rpm package from oracle-xe-11.2.0-1.0.x86_64.rpm.zip in redhat linux.By default i get database XE .My question is how can i create new database like XE i mean new instance.Please can any one suggest me how to do and please suggest me any blogs for this.
It doesn't matter what OS you use, you can run DBCA (Database Configuration Assistant) it is easy to create a database using this tool. Also pay attention to this question
I recently spun up a sql database on Windows Azure. I created a couple of tables and loaded some data. I then went into Sql Server Management Studio on my local machine and typed
Truncate table XXXX
And now it is clocking "Executing Query". Is truncate not supported by azure?
Tony:
I think you are right. I used the suggestion here and after resizing the db, all of the connections went away and I could truncate without a problem.
Thanks
