How to read the running parameter value for MaxNoOfConcurrentOperations and MaxNoOfConcurrentTransactions

[Dev Das]

We are running MySQL ndbcluster (Server version: 5.6.15-ndb-7.3.4-cluster).
While running update queries, we were repeatedly receiving the following error:
Got temporary error 233 'Out of operation records in transaction coordinator (increase MaxNoOfConcurrentOperations)' from NDBCLUSTER
As per MySQL documentation the config.ini was modified:
[NDBD DEFAULT]
MaxNoOfConcurrentOperations=1000000
MaxNoOfConcurrentTransactions=163840

After that we restarted the management, NDBD and API node(s). At this stage we are still receiving the error, and our question is:
How can the current(running) value of the parameters(MaxNoOfConcurrentOperations and MaxNoOfConcurrentTransactions) be read to ensure the changes made in both the node(s) did kick in.

Please suggest.

Thanks
