Here is an example of using cvendian to convert the endian of a CACHE.DAT file:
Usage: cvendian [-option] file1 [file2 ... file8]
-option = -b[ig], -l[ittle], or -r[eport]
Note: Running without an argument shows you usage
This database is little-endian.
This database has a block size of 8192 Bytes.
This database has 1 map.
The last block is 18432.
Original manager directory is c:\c2k1522\mgr\user\
18000 blocks (97%)
Done converting c:\C2K1522\mgr\user\CACHE.DAT to big-endian
Note: cvendian is an executable in the bin directory of you cache installation
The CACHE.DAT file should be dismounted before cvendian is run against it.
Also, if you do not know the endian of your two machines you can check fairly easily in cache like so:
%SYS>D ^%ST w %ST("indian")
It will display a 1 or a 0 depending on the endian of the system. Systems with matching endians do not need a conversion to be run in order to use each others databases
