To enable Unified Auditing in Oracle Database 12 and 18 on Oracle Linux I did this:
export ORACLE_SID=ORCLCDB cd $ORACLE_HOME/bin ./sqlplus sys as sysdba SHUTDOWN IMMEDIATE EXIT ./lsnrctl stop cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk uniaud_on ioracle cd $ORACLE_HOME/bin ./lsnrctl start ./sqlplus sys as sysdba STARTUP(more…)
Clone the repository with the official Oracle docker images:
git clone https://github.com/oracle/docker-images
Install docker, download Oracle Database, put it to the directory docker-images/OracleDatabase/SingleInstance/dockerfiles/18.3.0 containing the Dockerfile and run the following commands to build and run Enterprise Edition:
cd docker-images/OracleDatabase/SingleInstance/dockerfiles/18.3.0 mv ~/Downloads/LINUX.X64_180000_db_home.zip . sudo docker build -t oracle/database:18.3.0 --build-arg DB_EDITION=EE . sudo docker run -d -it --rm --name oracle18 oracle/database:18.3.0 sudo docker logs oracle18 --tail 100 sudo docker logs oracle18 | grep -i password
and the following commands to build and run Standard Edition 2:
sudo docker build -t oracle/database-se:18.3.0 --build-arg DB_EDITION=SE2 . sudo docker run -d -it --rm --name oracle18se oracle/database-se:18.3.0 sudo docker logs oracle18se --tail 100
the first string of the docker output contains the generated password for SYS, SYSTEM and PDBADMIN.
(more…)It is still possible to mine BEAM with GeForce GTX 1060 3GB and GMiner on HiveOS. GMiner takes 2862MB on GPU0 and 2850MiB on GPU1-7:
I successfully build and run rippled 1.1.2 on Ubuntu 18.04 with the following commands:
sudo apt-get -y install git cmake pkg-config protobuf-compiler libprotobuf-dev libssl-dev wget cd ~Downloads/ wget https://dl.bintray.com/boostorg/release/1.67.0/source/boost_1_67_0.tar.gz cd .. mkdir lib cd lib/ tar xvzf ~/Downloads/boost_1_67_0.tar.gz ./bootstrap.sh ./b2 -j1 export BOOST_ROOT=/home/user/lib/boost_1_67_0 cd ~/repos/ git clone https://github.com/ripple/rippled.git cd rippled git tag git show --summary 1.1.2 git reset --hard 1.1.2 mkdir build cd build/ cmake .. cmake --build . ./rippled -u(more…)
I followed the official Ubuntu time synchronization guide and installed chrony:
sudo apt update sudo apt install chrony cat /etc/chrony/chrony.conf chronyc sources chronyc sourcestats sudo systemctl restart chrony.service apt remove --autoremove chrony
After a few attempts I was able to start Ethereum Mist 0.11.1 in ‘fast’ mode on Windows 10:
it downloaded ‘geth’, connected to {“path”:”\\\\.\\pipe\\geth.ipc”} and started to sync, but when sync finished I was unable to send transactions (they were ‘denied’ for some reason).
I have 50 Mbit internet at home. If I test its speed with speedtest.net I get download speed 56 Mbit/s and upload speed 5.56 Mbit/s that is really good:
and if I download a file with torrent the speed is 6+ MB/s, but if I download a file with HTTP or SFTP the speed can be less than 500 KB/s that is 10 times slower. For example, if I download Ubuntu 18.10 on my VPS the speed is 24 MB/s:
I installed Node.js and Vue.js cli with the following commands
npm install -g @vue/cli npm install -g @vue/cli-init
and a sample application with
vue init webpack-simple my-vue-app cd my-vue-app npm install npm run dev
Ethash algorithm behaves a bit strange on my mining rig with HiveOS and 8 GTX 1060 3GB. Four MSI ARMOR cards with Sumsung memory (OC +1500 mem) have 24+ MH/s, two other cards (OC +600 mem) have 21+ MH/s and two other slow MSI cards (also OC +600 mem) have only 18+ MH/s. I tried to switch risers, PSU, PCI slots and move the cards across rigs, but with no success.
Today I did a pure experiment. I plugged one of the slow cards to a Windows 10 machine with 1000W PSU directly via PCI slot without riser, started Claymore Miner with Musicoin (that has a lower dag size than Ethereum) and got the same result as before, without OC the card had 15+ MH/s (normally it should be 19+ MH/s):
I have a mining rig with 8 GTX 1060 3GB connected via risers, the risers are connected via SATA power connectors to Corsair HX850. When the rig stopped working I noticed that one SATA connector on the PSU is molten:
