What should I do if I get locking errors from either the ISAM ODBC driver or my legacy application?

If you get locking messages when accessing your files in either Easysoft Data Access (EDA) for ISAM or a legacy application, the most likely reason is that your Easysoft locking mode in incorrect. Try changing it by using the following script, which is installed on the server:

cd /usr/local/easysoft/isam/lib
./disam_select.sh

These locking modes are available:

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 what version of C-ISAM you are running, cycle through all versions, One of them will set the locking mode correctly. The Easysoft software supports all locking modes for all versions of C-ISAM.
