Informix Error -43189: Logical Logs cannot be restored because LTAPEDEV value is <value>.

Cause and resolution

Logical Logs cannot be restored because LTAPEDEV value is <value>.

If the LTAPEDEV parameter value in your ONCONFIG file is /dev/null (UNIX) or NUL (NT) or blank, logical log restore cannot be performed. These are special values that you set to tell the server and ON-Bar that log backups are not desired. Data in the logical log cannot be restored.

Set the LTAPEDEV parameter value to something other than /dev/null (UNIX) or NUL (NT) or blank if logical log restores are desired. If logical log restores are not desired use the -w and -p options with ON-Bar commands to perform whole system, physical-only restore.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-43189 fires when LTAPEDEV in ONCONFIG is /dev/null (UNIX), NUL (Windows), or blank — per the official guidance, these special values mean log backups weren't wanted, so no logical-log data exists to restore.

LTAPEDEV set to /dev/null/NUL/blank, per the official guidance — the direct, only cause.

Solutions / Resolution

Set LTAPEDEV to something other than /dev/null/NUL/blank if logical-log restores are wanted, per the official guidance.
If logical-log restores aren't wanted, use the -w and -p options for a whole-system, physical-only restore, per the official guidance.

Examples

Whole-system, physical-only restore

$ onbar -r -w -p

Diagnostic Checks

Check ONCONFIG's LTAPEDEV value, and set it to a real device/file if logical-log restores are needed, or use -w -p if not.

LTAPEDEV is set to /dev/null/NUL/blank, so logical logs can't be restored — set a real value, or use onbar -r -w -p for whole-system, physical-only restore.
