Run as a daemon (–ud) You can run the LTM as a daemon on UNIX
operating systems. If you run in this manner, output is logged to the log file.
Operate in verbose mode (–v) Displays messages, other than LTL
messages, for debugging purposes.
The LTM configuration file
The Adaptive Server Anywhere and Adaptive Server Enterprise LTM
configuration files are very similar. This section describes the entries in the
Adaptive Server Anywhere LTM configuration file, and the differences from
the Adaptive Server Enterprise LTM configuration file.
The configuration file that an LTM uses is specified using the
-C command-
line switch.
The following table describes each of the configuration parameters that the
LTM recognizes. Parameters that are used by the Adaptive Server Enterprise
LTM but not by the Adaptive Server Anywhere LTM are included in this
list, and marked as either ignored (in which case they may be present in the
configuration file, but have no effect) or as unsupported (in which case they
will cause an error if present in the configuration file).
Parameter Description
APC_pw
The password for the APC_user login name. This
entry is present only in Adaptive Server
Anywhere LTM configuration files.
APC_user
A user ID that is used when executing
asynchronous procedures at the primary site.
This user ID must have permissions appropriate
for all asynchronous procedures at the primary
site. This entry is present only in Adaptive Server
Anywhere LTM configuration files.
backup_only
By default, this is off. If set to on, the LTM will
replicate only backed-up transactions.
batch_ltl_cmds
Set to on (the default) to use batch mode. Batch
mode can increase overall throughput, but may
lead to longer response times.
batch_ltl_sz
The number of commands that are saved in the
buffer before being sent to Replication Server,
when batch_ltl_cmds is on. The default is 200.
batch_ltl_mem
The amount of memory that the buffer can use
before its contents are sent to Replication Server,
when batch_ltl_cmds is on. The default is
256 kb.
