SQL CREATE DIRECTORY DUMPFILES1 AS '/usr/apps/dumpfiles1'; Then, a user on a UNIX-based client system using csh can assign the value DUMPFILES1 to the environment variable DATAPUMPDIR.

We can not delete primary transaction log file, but we can delete secondary log files.
Sometimes we can create a second log file on another disk as a workaround because the log file is full.
If we do not delete these temporary secondary log files over time, log file count will increase.
When we have free space on the disk where the first log file is located, or when we move this first log file to another disk with sufficient space, we can delete these temporary secondary log files.
To see how a second log file is added to the database, you may want to read the article “How To Add The Second Log File to the Database”.

ObjectiveAlarmODBC service continues logging alarms and events into SQL database. The size of database file (.mdf) and its transaction log file (.ldf) will grow over time. How to periodically purge old records from the database and dump the transaction log so that the database file and its transaction log file keep compact?
Procedure
A SQL Server Agent job can be created to delete old records in the database, then shrink the transaction log file (.ldf) and database file (.mdf). This SQL Server Agent job can be scheduled to run every day. Refer to the following steps:
- Make sure SQL Server Agent service is running. Launch SQL Server Management Studio, create a new job under 'SQL Server Agent --> Jobs'.
- Set the name of job to something like 'PurgeFixAlarms'. Assume the name of SQL database used by AlarmODBC service is 'iFix'. On 'Steps' tab, create the first Step like the following. The code below deletes those records that were created 90 days ago.
- Create the second step in this job like the following. Note, the following code assumes the SQL database name is 'iFix' and its transaction log file is 'iFix_log.ldf'.
- Create the third step in this job:
- On 'Schedules' tab for this job, create a new schedule for this job and configure the schedule to occur at a specific time every day, say 12:00:00 AM every day.
