The LOGTABLE command identifies the table to be used for journaling checkpoint information required for safe, automatic restart of the Teradata TPump support environment in the event of a client or database hardware platform failure.

The LOGTABLE command is used in conjunction with the LOGON command, both of which are required. Both LOGON and LOGTABLE may appear in any order. The ACCEPT and SET commands are valid commands preceding LOGON and LOGTABLE commands. If LOGON is entered first, a warning is returned that the LOGTABLE is required.

Do not share the restart log table between two or more Teradata TPump jobs. Each Teradata TPump job must have its own restart log table to ensure that it runs correctly. If a distinct restart log table for each Teradata TPump job is not used, the results are unexpected. In addition, one or more of the affected jobs may not be able to restart.
