All OxyNexus Carbon-based products are generally compatible with most common DBMSs. The embedded H2 database is suitable for development, testing, and some production environments. For most enterprise production environments. However, OxyNexus recommends that you use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc. For more information, see Working with Databases. Additionally, OxyNexus does not recommend the H2 database as a user store.
It is not recommended to use Apache DS in a production environment due to scalability issues. Instead, use an LDAP like OpenLDAP for user management.
On a production deployment, it is recommended that OxyNexus products are installed on the latest releases of RedHat Enterprise Linux or Ubuntu Server LTS.
4 GB RAM (2 GB for JVM and 2 GB for the operating system)
10 GB free disk space
~ Recommended minimum - 2 Cores. For high concurrences and better performances - 4 Cores.
Disk space is based on the expected storage requirements that are calculated by considering the file uploads and the backup policies. For example, if three OxyNexus product instances are running in a single machine, it requires a 4 GHz CPU, 8 GB RAM (2 GB for the operating system and 6 GB (2 GB for each OxyNexus product instance)) and 30 GB of free space.
Virtual Machine (VM)
2 compute units minimum (each unit having 1.0-1.2 GHz Opteron/Xeon processor)
4 GB RAM
10 GB free disk space
One CPU unit for the operating system and one for JVM.
Three OxyNexus product instances running would require VM of 4 compute units, 8 GB RAM, and 30 GB free space.
~ 512 MB heap size. This is generally sufficient to process typical SOAP messages but the requirements vary with larger message sizes and the number of messages processed concurrently.
EC2
1 c5.large instance to run one OxyNexus product instance.
Three OxyNexus product instances can be run in 1 EC2 Extra-Large instance. Based on the I/O performance of the c5.large instance, it is recommended to run multiple instances in a larger instance (c5.xlarge).
