It is best to install your OASIS database on a hard drive that has plenty of available space. Depending on the size of your office and the amount of attachments you plan to store in OASIS, we recommend anywhere from 25 GB to 100 GB of free space for medium-sized groups. We have found that attachments tend to grow exponentially (for many groups) year over year. If you notice your disk space dwindling, you might want to consider adding more space before the drive reaches capacity and you incur downtime.
We cannot stress enough the importance of a reliable, verifiable, routine backup system. The database should be backed up daily and the integrity of those backups should be verified from time to time. OASIS has a built in daily backup so you should plan to have either a second physical hard drive for the backup to be directed to, or have a RAID array to add a layer of protection in the event of a hardware failure.
There is nothing more frustrating than finding that your backup is not useful when the server crashes. It has happened before and we have shared in the frustration. We will be here to help restore your data, but it comes at a price as data recovery will cause hours or days of downtime.
General guidelines for best performance
- If your office wants to go as paperless as possible, attaching files and drawings, etc will cause the size of the OASIS database to grow exponentially. Plan ahead for this by having plenty of free hard drive space for future growth.
- Hard disk performance on the server is VERY important. Internal server bus speed is important as well for large offices. Standard 7200 RPM drives are not recommended. Using a quality RAID card and 10K RPM drives will result in better performance and stability. This is recommended for larger companies.
- Attachments/storage of documents, transactions, emails, etc within OASIS is only limited by the amount of hard drive space on the server (or PC used as server) and the page size of the database.
- Allocating more RAM to the server will result in better performance vs allocating more processing power to the server. However, adding memory after 8 GB will not result in a noticeable performance increase unless the database is larger than 500 GB.
- More modern operating systems will use more memory, but will run faster overall.
- Databases like SAP SQL Anywhere (used in OASIS) will tend to compete for resources when run with other applications like email servers (ie. Microsoft Exchange), other database servers, and web servers. For best results, it is best to host the OASIS database on either its own dedicated hard drive or on a RAID array where the I/O load is shared.
- USB 3.0 is highly recommended on the server. In the event of a database recovery from an external backup drive, a USB 3.0 drive will move data up to 5 times faster than a USB 2.0 drive.
Common issues concerning desktop systems running OASIS:
- Out-of-date printer drivers may result in OASIS print failures or garbled print from time to time. There have been some issues with Windows 7 and printers. Consult your IT person for updates and printer driver issues.
- Some network adapter drivers are not optimized for use with OASIS. One of the common problem settings is for energy efficiency, which will turn off the network adapter to save power. The result is slow OASIS performance when building submittals, for example.
- We have encountered several different antivirus programs that will analyze EVERYTHING that is transmitted to and from your machine. In ALL cases this will slow down OASIS, as it is a client/server application that transmits a great deal of data over the network. Consider adding exceptions for OASIS.
- Using Roaming Profiles in Active Directory to store user profiles remotely on a server can cause OASIS to run very slowly depending on how it is set up. Contact us for information on how to bypass this issue.
Web Hardware and Software
The OASIS Web products assume a web server and a high quality, well-secured LAN. This often involves a DMZ with a dedicated web server and VLANs for security. Before implementing these technologies, please call Ingen Software. Regardless, a local LAN specialist is highly recommended if these technologies are to be implemented at the local agency.
