After the LST SUBDATA command is executed, the output displays error 3087, as
shown below:

%%LST SUBDATA: RESULT=CountOfSub, COND=AllSub;%%

ERR3087:Resource is in use
There is together 1 report

--- END

ERR3087 is an error defined in V600R003C04.
The execution of the LST SUBDATA command affects the system performance
severely. If the command is executed before the execution of the previous LST
SUBDATA command is complete, a fault may occur. To avoid such fault, the HDU of
V600R003C04 or later version creates a temporary empty file as a sign (sign file)
when the LST SUBDATA command is executed. After the file containing the query
result is sent to the SMU server, the sign file is deleted automatically. If a sign file is
detected when the LST SUBDATA command is executed, it is regarded that the
execution of the previous LST SUBDATA command is ongoing. Then, ERR3087 is
generated.
In addition, if the system runs improperly, the sign file cannot be deleted
automatically even if the execution of the LST SUBDATA command is complete.
Thus, ERR3087 is generated each time the command is executed. In this case, you
must delete the sign file manually or restart the SMF.

Check whether the check.tmp file exists under the directory /opt/hlr/hdu/bin on the
HDU. If yes, delete the file, and then run the LST SUBDATA command. If the error is
generated again, stop the SMF process. The fault can be rectified after the BAM
Manager starts the SMF process automatically.
