Review the STA File System Layout

Review the file system layout recommendations to plan your configuration before installing Linux.

Create the file systems during the Linux installation and ensure that the Oracle user has write privileges to the required file systems before STA installation. The STA installation will fail if the Oracle user does not have proper write privileges.

The table below describes the recommended layout and space allocations for a typical installation. For larger installation, see Server Sizing and Considerations for Larger Installations.

Note:

All directories must be mounted before starting STA (including any auto-mounted directories). For performance reasons, Oracle does not recommend that the /dbdata, and /Oracle directories use NFS mount points.

Oracle recommends that usage for any partition should never exceed 80 percent. After installing STA, you can configure the Resource Monitor to automatically notify you if usage exceeds a high-water marks. See the STA Administration Guide for instructions. You need to periodically check locations not monitored by the Resource Monitor.

Table 3-1 Recommended File System Layout

File System	Default Mount Point	Size	Description and Recommendations
root	/	32 GB min.	root file system. Space requirement is for files and directories critical for system operation. See entries below for additional space requirements if the temp and STA logs directories are also located in this file system.
temp	/tmp	11 GB min.	Location of temporary files. At least 4 GB of free space is required in temp for STA installations and upgrades.
STA logs	/var/log/tbi	30 GB min. 50 GB to 100 GB suggested	Location of STA logs and STA database binary logs. This location should be a separate volume at a separate mount point. The default location is /var/log/tbi, but you can change this location at any time after STA installation; see Relocate the STA Logs Directory (optional) for instructions. Note: The contents tend to grow over time. Except for log rotation, STA does not perform space management. Note: Incremental database backups (binary files) in /STA_logs/db may consume significant space but are purged every 24 hours by the STA backup utility. See the STA Administration Guide for details on configuring their frequency.
swap	None. Defined as memory.	50 to 100 percent of RAM size	Used for swap space.
Oracle storage home	/Oracle	30 GB min. 100 GB suggested	Location of the STA and Oracle Middleware (WebLogic, MySQL, RDA) application files. This location is user-defined. This location should be a separate file system on a separate volume. Maintain a minimum of 11 GB free space for STA installations and upgrades. Maintain an additional 5 GB free space for WebLogic log rotation. STA automatically creates the following Oracle Middleware subdirectories: Rotated WebLogic logs: /Oracle_storage_home/Middleware/user_projects/domains/TBI/servers RDA last CLI snapshot: /Oracle_storage_home/Middleware/rda/output STA GUI snapshot log bundles: /Oracle_storage_home/Middleware/rda/snapshots
STA database location	/dbdata	250 GB to 2 TB	Location of the STA database. This location is user-defined. Oracle highly recommends you place this directory on its own volume, separate from root, swap, Oracle storage home, and the STA logs location. For performance, backup, and maintainability, best practice is to use a separate set of mirrored or striped drives. Required size depends on the number of libraries, drives, media, exchanges per day, and historical years of data. Oracle recommends that you configure STA services to alert if space utilization exceeds a specified percentage.
STA database local backup location	/dbbackup	70 to 80 percent of /dbdata size	Location of the most recent local database backup. This location is user-defined. Oracle recommends that this directory be on a different volume from the STA database, and on mirrored or striped drives in case of database corruption or failure.
