Logs for Parallel Export and Import Processes
Definition
This section describes the logs generated when export or import processes run in parallel. For more information, see
Parallel Export and Import.Use
Export and import processes can run in parallel when the following functions are used in SAPDBA:
SAPDBA Function |
Main Log |
Reorganization ® Reorganize list of tables or indexes |
<timestamp>.rli |
Reorganization ® Reorganize tablespace |
<timestamp>.rtc |
Reorganization ® Reorganize tablespace and datafiles |
<timestamp>.rtd |
Export/import ® Export tables and indexes including data |
<timestamp>.exd |
Export/import ® Import tables and indexes including data |
<timestamp>.imd |
Structure
When several parallel export or import processes are started, partial, temporary logs are written in addition to the main logs listed above. The temporary logs are stored in the directory:
<working directory>/<timestamp>
The temporary logs are called:
exp|imp<TSP>_<n>.log
(n=2,...,number of processes)exc<TSP>_<n>.log
(n=1,....,number of processes)The actions of the first process are recorded in the main log. From the second parallel import or export onwards, partial temporary logs are written. After the completion of the last export, the partial logs are appended to the main log and are then deleted. The temporary logs are not displayed on the screen during interactive processing.
Integration
If SAPDBA cancels an import or export in progress, the partial logs are kept and not appended to the main log.
