Importing File in a Cluster
In Adabas Cluster, you can import files on the primary node of a cluster environment with the ADAORD utility.
Importing files on a secondary node will be rejected with the following error message:
ADABCK-E-CLUSTER, In a cluster this operation is only allowed on the primary node
The input file (ORDEXP) is automatically replicated to all secondary nodes. The ADAORD output shows in the nucleus log on the secondary nodes.
If the replication to the cluster fails, the import will not be completed on the primary node.
When a file is successfully imported to the cluster, a copy of the input file is stored in the database directory on the secondary nodes. You can specify a different directory with the environment variable ADA_CLUSTER_FILE_DIR. The copy on the secondary nodes is deleted after a successful import.
Ensure that sufficient space is available in the database of the secondary nodes or the custom directory with the nucleus parameter OPTIONS=AUTO_EXPAND.
The following example shows how to import a file in a cluster:
1. Display cluster status.
