The names of the Managemane Units are missing

Products

• Automic Dollar Universe

Issue/Introduction

Management Units (MUs) may appear without names or disappear entirely from the list after the hosting partition or disk (e.g., drive C: on Windows) becomes saturated. This corruption occurs when the Dollar Universe Application Server (DUAS) cannot complete writes to the administration tables during a disk-full event.

Environment

• Product: Dollar Universe Application Server version 7.x

Cause

Disk saturation prevents the IO server from correctly updating the Management Unit definition files. This leads to a mismatch between the index (.idx) and data (.dta) files, specifically affecting u_fxmu60, u_fttg60, and u_ftts60.

Resolution

To resolve this issue, restore the administration data files from a backup taken prior to the disk saturation event.

1. Reclaim disk space on the affected partition to ensure sufficient room for operations.
2. Stop the DUAS node:
   • Windows: unistop (or stop services via Control Panel)
   • Unix/Linux: $UNI_DIR_EXEC/unistop
3. Identify a valid backup of the following files:
   • u_fxmu60.dta and u_fxmu60.idx (MU Definitions)
   • u_fttg60.dta (Administration Table)
   • u_ftts60.dta (Administration Table)
   • Note: All restored files must have the same timestamp to maintain referential integrity.
4. Replace the corrupted files in the data directory with the backup versions.
5. Perform an offline reorganization:
   • Windows: %UNI_DIR_EXEC%\unireorg
   • Unix/Linux: $UNI_DIR_EXEC/unireorg
6. Start the DUAS node:
   • Windows: unistart
   • Unix/Linux: $UNI_DIR_EXEC/unistart
7. Verify the Management Units appear correctly in the Univiewer Console.
