V5.2 and V5.3 command-line administrative clients can administer Tivoli
Storage Manager V5.2 and V5.3 servers, and the V3.1 VM server.
The Motif native GUI on UNIX clients was not migrated to V5.3. The Java GUI
client should be used instead.
Error log behavior change
Beginning with V5.3, client applications will not run without a writable log. If you
start dsmadmc or dsmc as non-root, and if the option ERRORLOGNAME in
dsm.sys points to a file that is not writable by non-root users, error message
ANS1398E is displayed and the session does not start.
The following new rules apply (using dsmerror.log as an example, but all logs are
treated equally). The different error logs for the backup-archive client are
explained in "Environment variables" on page 113 under DSM_LOG:
1. If the log does not exist, it will be created as follows (with default
permissions):
– With the name and in the directory specified in the ERRORLOGNAME
option.
– If the ERRORLOGNAME option is absent, the log will be created with the
name dsmerror.log in the directory specified in the DSM_LOG
environment variable, if present.
– Otherwise, the log will be created with the name dsmerror.log in the
current working directory.
– Because default permissions are used, a log created by the root user
might not be writable by any other user. If this is the case, the root user
must set the proper permissions or ACLs to allow free use of the Tivoli
Storage Manager application by all users who need to use it.
2. If the log is successfully created, an error-free session will leave a zero-length
(empty) log file.
3. The client does not attempt to create logs in the root directory. ANS1398E is
displayed when the method in rule 1 directs the log file to be created in the
root directory.
4. If a log file exists and can be located using the method in rule 1, it will be used
(and it can be in the root directory if you choose). Furthermore, whatever
permissions you give that log file will be preserved by Tivoli Storage Manager.
We recommend that you create your log file before running the client, to make
sure all eligible users have write access to that log. Use the ERRORLOGNAME
option or the DSM_LOG environment variable to designate your predefined log
file.
