Should ext01 and ext02 be in a-tree or u-tree?

Description:
Should the ext01 and ext02 libraries be in the a-tree or the u-tree?
Resolution:
The as-delivered Aleph 22 aleph_start has the extnn libraries in the a-tree:
setenv ext01_dev ${ALEPH_MOUNT}/a${ALEPH_VERSION}_$ALEPH_COPY
setenv ext02_dev ${ALEPH_MOUNT}/a${ALEPH_VERSION}_$ALEPH_COPY
If these lines have not been changed to "${ALEPH_MOUNT}/u..." or if such lines have not been added to ./aleph_start.private, then the a-tree version is active.
The following commands can be used to confirm this:
> dlib ext01
> dt
>pwd
(This will show the full path: either "a22..." or "u22...".)
If no local changes are needed, then it is best to leave the extnn files in the a-tree. But placing the files in the u-tree and updating aleph_start.private with these lines is OK:
setenv ext01_dev ${ALEPH_MOUNT}/u${ALEPH_VERSION}_$ALEPH_COPY
setenv ext02_dev ${ALEPH_MOUNT}/u${ALEPH_VERSION}_$ALEPH_COPY
Additional Information
As described in Article 000043288, the extnn libraries have no Oracle data ( Should EXT01 have tables defined? ).
As described in Article 000038219, they are primarily used with z39.50. ( How do I customize Z39.50 search results screens? ).
