Problem of Inactive, No Manager in one of the request submitted:

This problem seems to be inactive ICM.
When ICM is not up u will get error inactive-no manager.
Just check with manager and make it up.
ps -ef|grep LIBR
if it shows the manager is down then start the CM using script adcmctl.sh.
And if the manager is up but it is showing the inactive-nomanager then check for the log file and do the needful.
As my idea y dont u try with cmclean.sql.(not supported by oracle)
1.Bring down CM.
2.run cmclean.sql
3.Bring up CM.
