After Installing Zen on Linux, macOS, or Raspbian
The following topics may be useful after you install Zen on Linux, macOS, or Raspbian:
Verifying Installed Products with RPM
The following table provides commands with which you can verify which packages the RPM packager installed. The commands are case sensitive.
Zen Package
RPM Command to Verify Installation
Enterprise Server
rpm -q Zen-EnterpriseServer-linux
Cloud Server
rpm -q Zen-CloudServer-linux
Client 64-bit
rpm -q Zen-Client-linux
Returns the specific client version installed (Zen-Client-release-build).
Client Access 32-bit
rpm -q Zen-Client-Access-linux
Returns the specific client version installed (Zen-Client-Access-release-build).
Note:  The 32-bit Client Access package should always be installed after a 64-bit product.
Community
rpm -q Zen-Community-linux
All installed
rpm -qa | grep Zen
Verifying Database Engine is Running
Optionally, after the installation script finishes, you can verify that the database engine is running with the ps command. To do this, enter the following at a command prompt:
ps -e | egrep mkded
Server Configuration
Generally, the default configuration settings for Zen Enterprise Server and Cloud Server are sufficient. See Configuration for settings that you may want or need to set.
If you want to explore all of the configuration settings, see Configuration Reference in Advanced Operations Guide.
Client Configuration
All configuration settings for Zen Client are discussed in Linux, macOS, and Raspbian Client Configuration Properties in Advanced Operations Guide.
Linux, macOS, and Raspbian Clients and the Monitor Utility
This information applies only to Linux, macOS, or Raspbian clients that use a static IP address. Ignore it if you use DHCP and have a DSN to resolve named addresses.
When you monitor clients using the Zen Monitor utility, the client IP address that gets transmitted across the network originates from the hosts file. If the system name and IP have not been added to the hosts file, network communication uses the local host IP address, which is 127.0.0.1 or ::1 (a loopback address).
If you change the loopback address to the correct IP, or if you add the system name and IP to the hosts file on the client, the client name is displayed correctly in the Monitor utility.
Licensing
Once you have completed installation, you may need to update your license to increase the user count for Zen Enterprise Server, or to increase the session count or data in use limits for Cloud Server. See Increase User Count or Data in Use in Zen User’s Guide.
Common Questions After Installation
If you have problems with your installation, see Troubleshooting After Installation or get help online from the Zen knowledge base at the Actian website. The following are common questions after installation of the products:
