Portal upgrade performance issues
When the entropy of the system is very low, cryptographic functions takes considerable amount of time.
Following are the examples of low entropy:
while adding new data collector on Portal, takes longer time to generate the key file.
Upgrade of Portal hangs when upgrading internal objects.
Aptare agent service takes longer time when started to get the
collectorconfig.xmlfrom data receiver side.checkinstall.shfile execution takes longer time than expecting.
These issues are observed on Linux Platform.
The following solution is recommended:
Note:
Download and install rng-tools rpm on the Portal.
For RHEL/OEL, execute the following steps to install the rng-tools and start the services:
Access command prompt.
Type yum install rng-tools to install the rng-tools.
Type systemctl start rngd to start the services.
Type systemctl enable rngd to enable the services.
For Suse, execute the following steps to install the rng-tools and start the services:
Access command prompt.
Type zypper install rng-tools to install the rng-tools.
Type systemctl start rng-tools to start the services.
