Error description
Product: Tivoli Network Manager Version: 3.8, 3.9 Component: Log file rotation Problem: By default, there is no limit to the size logs can grow to. In addition the documentation needs to be updated to say the default limit is 1GB and add a note on estimating log space for planning.
Local fix
UNIX: modify ncp_control.sh to check if NDE_LOGFILE_MAXSIZE and NDE_LOGFILE_ROTATION_TIME variables have been set. If neither exists, then set NDE_LOGFILE_MAXSIZE to 1GB. No change for Windows, except the documentation should note that there is no default limit to the log size and users should set a limit using the NDE system environment variables if desired.
Problem summary
**************************************************************** * USERS AFFECTED: * * Users in Unix Platforms * **************************************************************** * PROBLEM DESCRIPTION: * * The ncp_poller process crashes due to trace files reaching 2 * * GB in size.

Problem conclusion
On UNIX systems, ncp_control.sh checks if the NDE_LOGFILE_MAXSIZE and the NDE_LOGFILE_ROTATION_TIME variables have been set. If neither of them exists, then the NDE_LOGFILE_MAXSIZE environment variable is set to 1GB. Note that setting NDE_LOGFILE_MAXSIZE to 1 GB is only done if the user has not set the NDE environment variables for the account running the Netowrk Manager core processes. On Windows systems, there is no default limit to the log size, if required, set a limit using these variables as system environment variables.
