Can someone explain how to avoid Communication Error by SAP DB Loader's
TABLEEXTRACT command?
Environment :
* SAP DB 7.4.
* There are ~1.2 M records in the table test.
* SAP DB Extended Configuration Parameter SESSION_TIMEOUT set to 0 and
REQUEST_TIMEOUT has default value 5000 (seconds).
Invocation (Java API):
...
Properties prop = new Properties();
prop.setProperty("dbname","sapdb");
prop.setProperty("dbroot", "D:\\TEST\\");
prop.setProperty("user","test");
Loader loader = new Loader(prop);
loader.cmd("USE USER TEST TEST");
loader.cmd("TABLEEXTRACT TABLE test DATA OUTSTREAM FILE
'D:\\TEMP\\test.txt'");
...
Result:
Exception thrown:
com.sap.dbtech.rte.comm.CommunicationException: Communication Error
