Suppose you cannot see BCOL.1.1 when you execute dccmd status all. Below, some things to investigate:
1) Try to run it manually. Run:
dccmd start BCOL.1.1
2) Check the proviso.log. Run:
grep "BCOL\.1\.1" proviso.log and search for any error message
3) If you see a WALKBACK error on the log, search for the walkback file and read the first lines to see the main reason for the walkback
4) Check if the component configuration exists in the database. Run:
dccmd debug CMGR "self dbCfgPrint" | grep BCOL.1.1
This should show the component configuration in the database. Check for any mistakes and correct it using the topologyEditor
If you don't see any value, the component was not created on the topologyEditor or was not saved correctly in the database.
5) Check if any filesystem is full. Run:
df -kh and make sure no partition has 100% utilization
6) Restart some datachannel manager components (cmgr, amgr, cns) and try again.
If you still cannot find the reason, it is a good moment to open a ticket towards IBM
