Troubleshooting

These are the most common errors you can run into using the isCOBOL Driver for File Server.

100	A duplicate key was detected where duplicates are not allowed.
102	This indicates that a routine was called with an illegal parameter. For example, specifying a key number that is larger than the number of keys in the file would result in this error.
104	An attempt was made to open more files than the system allows open at once.
105	The index file is corrupt or the physical disk file does not match the type of file being opened. If the index file is corrupt, it should be reconstructed using the appropriate host system utility. The exact nature of this corruption is identified by "f_int_errno."
107	The requested record is locked by another process or (for some systems) by another file handle used by this process.
111	The requested record was not found.
112	The current key of reference was in the "undefined" state when the "i_next" or "i_previous" routines were called. There is no current record from which to read forwards or backwards.
113	The file is locked against the current open mode.
116	The system ran out of dynamic memory.
117	An operation was requested that the current open mode doesn't allow. For example, attempting to add a record to a file that is open for input-only would result in this error.
126	The requested operation is not supported by this host system.
127	The disk became full while adding the new record.
128	The size of the new record doesn't match the type of file being opened.
129	The system ran out of lock-table entries.
130	The file is missing.
131	Invalid permission for the operation.
