Clustering provides high-availability, scalability, and manageability of the resources and applications by grouping multiple servers that are running Adeptia Suite. There are a number of components, which make that possible. Important components of clustering service include the following:
...
- Adeptia Suite does not provide Clustering or Failover setup for the databases, however, you can set that up according to the database you use. For load sharing purposes, it is recommended to configure primary/secondary or replication (refer to the related database documentation).
Log Database:
Adeptia Suite maintains logs of all the design time and run time activities that you run within Adeptia Suite. For example Process flow log, event log, etc. Adeptia Suite writes all these logs into the log database. All the nodes of the cluster should use same log database. In addition, for load sharing purposes, it is recommended to configure primary/secondary or replication (refer to the related database documentation).
...
When the process flow is executed, data from the source is converted to the intermediate form and then it is dispatched to the target. The intermediate data is stored in a repository folder. This should be a shared folder in the network, which can be accessed by all the nodes of the cluster. There should not be any username/password required to connect to this folder.
Recovery Folder
During execution of a process flow, its current state is stored in a recovery file. These recovery files are stored in a recovery folder. The recovery file, remains in the recovery folder unless the process flow execution is completed. This folder should also be shared among all the nodes of the cluster.
