Troubleshooting
1
When I use
Export DB as SPTGEN
with 3DES, the system freezes up.
3DES is a very powerful encryption algorithm and requires a lot of CPU power. It is suggested
that you perform the function during an off-peak period or offline. It will be safer and won’t
affect usage performance.
2
The hard disk storage is almost full.
Backup files will stay in the directory “
home\apache2\hotdocs\PS\bkup\mysql\
” unless
deleted or moved. The system Administrator should be responsible for managing these files.
When the hard disk storage approaches its limit, the system Administrator should archive
(move) the files to another location.
If there is still not enough space, you should expand your storage space by adding new
hardware.
3
Why is it suggested to disable the Linux firewall on this server?
It is better to have a dedicated firewall device. This allows the server to dedicate more
resources to the provisioning service.
4
Is there any solution to provide redundant databases?
MySQL supports one-way replication. One server acts as the master, while one or more other
servers act as slaves (refer to
). The master server writes updates to its
binary log files and maintains an index of the files to keep track of log rotation. These logs
serve as a record of updates to be sent to slave servers. When a slave server connects to the
master server, it informs the master of its last position within the logs since the last
successfully propagated update. The slave gets any updates that have occurred since then, and
then blocks and waits for the master to notify it of new updates.
A slave server can also serve as a master if you want to set up chained replication servers.
Note that when you are using replication, all updates to the tables that are replicated should be
performed on the master server. Otherwise, you must always be careful to avoid conflicts
between updates that users make to tables on the master and updates that they make to tables
on the slave.
One-way replication has benefits for robustness, speed, and system administration:
• Robustness is increased with a master/slave setup. In the event of problems with the
master, you can switch to the slave as a backup.
