Action Environment sets an operating system environment variable for the HVR process which connects to the affected location. It also affects an agent called for this location.
If this action is defined on a specific table, then it affects the entire job including data from other tables for that location.
Parameters
This section describes the parameters available for action Environment.
Parameter | Argument | Description |
|---|---|---|
| Name | env_var | Name of the environment variable. |
| Value | path | Value of the environment variable. |
Context | ctx | Ignore action unless Refresh or Compare context ctx is enabled. The value must be the name of the context (a lowercase identifier).

Examples
Variable | Description |
|---|---|
HVR_LOG_RELEASE_DIR PostgreSQL
| Specifies alternative directory for reading DBMS backup log files. The value points to an alternative location where HVR can find the backups of the transaction files (alternative to where the database dictionary indicates they are). This variable is similar to the location property Archive_Log_Path. PostgreSQL needs this for locating the archive files. |
HVR_SORT_BYTE_LIMIT | Amount of memory to use before sorting large data volumes in temporary files. The default limit is 512Mb. |
HVR_SORT_ROW_LIMIT | Number of rows to keep in memory before sorting large amounts of data using temporary files. The default limit is 10Mb. |
