If you do find that you are getting locking messages when accessing your files when both EDA for ISAM and a native application are accessing the ISAM files the most likely reason is that your Easysoft locking mode in incorrect. Try changing it by using the following script installed on the server:

cd /usr/local/easysoft/isam/lib

./disam_select.sh

You should then see the following:

Disam Locking Mode Selection

** NOTE : All locking modes may not be available on all platforms **

1. Disam 96 (ISLOCKING = 1 C7LOCKING = 0) (cisam pre 4.1)
2. Disam 96 (ISLOCKING = 2 C7LOCKING = 0) (cisam pre 5.0)
3. Disam 96 (ISLOCKING = 2 C7LOCKING = 1) (cisam 5.0 > 7.1) [default]
4. Disam 96 (ISLOCKING = 2 C7LOCKING = 2) (cisam 7.2)
5. Disam 96 (ISLOCKING = 2 C7LOCKING = 2) (cisam 7.26)

Select required locking mode? (1-5) [3]:

If you do not know the version of C-ISAM that you are running cycle through all versions and one of them will set the locking mode correctly as the Easysoft software has been coded to support all locking modes for all versions of C-ISAM.
