A - Generally speaking, you don't need to change PSQL parameters after the installation. There are two optional changes you can consider:
- Change the Btrieve Security Mode to "Mixed." This is necessary if you intend to implement NTFS security for Elliott. Please reference the following article for more detail on implementing NTFS security for Elliott: http://support.elliott.com/knowledgebase/articles/654601-elliott-8-directory-structure-and-ntfs-rights.
- By default, any Btrieve file size is limited to 2GB. If the file exceeds 2GB, it will create another segment file with extension like ^01. Then another one with ^02, ^03, and so on and so forth. The system supports up to a maximum 32 Btrieve segment files with a maximum file size of 64GB. We suggest instead of limiting each segment to 2GB, that you allow the system to create Btrieve files larger than 2GB.
Change Btrieve Security Mode to "Mixed"
To change the Btrieve Security Mode to "Mixed," you need to bring up the PSQL Control Center. Under the "Engines" node, expand the "Database" node, right click on the "DEFAULTDB" database and choose "Properties." See sample screen below:
In the Properties window for DEFAULTDB, highlight "Security" on the left side and click on the "Btrieve Security" tab on the right side. Change the default selection from "Classic" to "Mixed." See sample screen below:
Click Apply or OK to save. The parameter you change here will not go into effect until you restart the PSQL engine. If you don't see DEFAULTDB, then there's something wrong with your installation. Please contact us before proceeding.
Turn Off Btrieve File Size 2GB Limitation
To turn off the Btrieve file size limitation, you need to bring up the PSQL Control Center. Under the "Engines" node, right click on the server node and choose "Properties." See sample screen below:
In the properties window, highlight "Performance tuning" on the left. By default, "Limit Segement Size to 2GB" is checked. Un-check it and click "OK" or "Apply" to save. See sample screen below:
You will receive a message asking if you wish to restart the PSQL server engine. You can either choose to do it now or later to let the new parameter take effect.
