DUAS6: Node stops when FATAL message appears in universe.log

Products

• CA Automic Dollar Universe

Issue/Introduction

Product Version: Dollar.Universe 6
Is it normal that Dollar Universe stops when one of the FATAL messages appear in universe.log?
Which error messages appear when we reach a limit on file system?

Environment

OS: All

Cause

By design.
Dollar Universe 6 stops itself to avoid data corruption in case there is no more space in the filesystem.

Resolution

Please find the messages related to the node settings :

- U_FS_DATA_WARN_TH (Warning threshold for the monitoring of the available space of the data and tmp file system (MB))
-> ***** Low available space on DATA file system () ( MB) *****
-> ***** Low available space on TMP file system () ( MB) *****

- U_FS_DATA_STOP_TH (Critical threshold for the monitoring of the available space of the data and tmp file system (MB))
-> ***** Available space on DATA file system too low () ( MB). Stopping DUAS server *****
-> ***** Available space on TMP file system too low () ( MB). Stopping DUAS server *****

- U_FS_LOG_WARN_TH (Warning threshold for the monitoring of the available space of the log file system (MB))
-> ***** Available space on LOG file system too low () (MB). Stopping DUAS server *****

- U_FS_LOG_STOP_TH (Critical threshold for the monitoring of the available space of the log file system (MB))
-> ***** Low available space on LOG file system () (MB) *****

- U_FS_FILESIZE_WARN_TH (Warning threshold for the monitoring of the size of the .dta and .idx files (MB))
-> ***** Size of file [] has reached warning threshold. ( > bytes) *****

- U_FS_FILESIZE_STOP_TH (Critical threshold for the monitoring of the size of the .dta and .idx files (MB))
-> ***** Size of file [] has reached critical threshold. Stopping DUAS. ( > bytes) *****

There are too the following messages format when the size is back to normal:

For dta/idx files:
Size of file [] back to normal ( < bytes)
For data / tmp directories:
Available space on TMP file system () back to normal ( MB)
Available space on DATA file system () back to normal ( MB)

For log directory
Available space on LOG file system () back to normal ( MB)


It is normal that Dollar Universe stops when the FATAL message appears in universe.log
It is up to the Dollar Universe administrator to either increase the FileSystem space / archive some logs before starting again Dollar Universe.
