ps -ef|grep d.bin output is appended with "1-"
In two node RAC 11.2.0.4 on linux, ps -ef|grep d.bin output is appended with "1-" for some processes
root 56857 1 0 2018 ? 1-07:07:05 /u01/grid/oracle/product/11.2.0.4/grid/bin/ohasd.bin reboot --> "1-"
root 57167 1 0 2018 ? 1-04:28:11 /u01/grid/oracle/product/11.2.0.4/grid/bin/orarootagent.bin --> "1-"
oracle 57168 1 0 2018 ? 1-05:25:03 /u01/grid/oracle/product/11.2.0.4/grid/bin/gipcd.bin --> "1-"
what is the reason for this and what does this mean?
