症狀

  • The NetWorker system is on a Linux/UNIX operating system.
  • NetWorker 19.7.0.1 or prior is installed.
  • The nsr_shutdown command is issued to stop NetWorker services but fails with the following error.
nwsystem:/ # . /usr/bin/nsr_shutdown
ksh: TIMEOUT: This variable is read only.
nwsystem:/ #

原因

The nsr_shutdown unix script uses "TIMEOUT" as a local variable but this is actually a well-known global environment variable which can be made globally read-only by the user. When this happens, nsr_shutdown fails when it tries to set the TIMEOUT variable.

解析度

Workaround

Edit the /usr/bin/nsr_shutdown script and change all instances of the variable TIMEOUT to any other variable name, example NSR_TIMEOUT.

Example:

TIMEOUT=`expr $TIMESTAMP + $TIMETOKILL`
        while [ "`cat $NSR_SERVICES`" ] && [ $TIMEOUT -gt `GetTime` ]; do

Change to:

NSR_TIMEOUT=`expr $TIMESTAMP + $TIMETOKILL`
        while [ "`cat $NSR_SERVICES`" ] && [ $NSR_TIMEOUT -gt `GetTime` ]; do

 

NetWorker engineering has updated the script to use a different variable. This fix will be incorporated in the next cumulative hotfix version of 19.7 after 19.7.0.1.
