DBCollect/Install
Summary
Installing DBCollect is pretty simple: download the latest dbcollect zipapp, put it somewhere in $PATH, and make it executable.
Requirements
Operating Systems
- Linux
- Enterprise Linux 6 (EL6) or higher (RHEL, OEL, CentOS, Rocky Linux)
- SPARC/Solaris
- IBM AIX
On IBM AIX, you need to install Python first. You can get python for AIX from AIX Toolbox (IBM)
Make sure it is executable and available in $PATH.
Simply running python should then work.
Python
DBCollect is a Python ZIP app
- Requires Python (2.6+ or 3.x)
- On Linux (EL6+) works out of the box
- On AIX/HP-UX, need to install Python first, Windows not supported
A Python ZipApp is a standard ZIP file with an additional "shebang" prepended: #!/usr/bin/env python
- This causes dbcollect to be called with whatever ‘python’ version is in $PATH
- If this does not work, manually run python: ‘/usr/bin/python3 /usr/local/bin/dbcollect <options>’
- Executable can be inspected with
unzip –v /usr/local/bin/dbcollect - Run simply as root or as ‘oracle’ user/owner
Oracle
- Oracle RDBMS 11g or higher (optional)
- Diagnostics pack license OR statspack configured on the database(s)
- Access to the 'oracle' special user or dba privileges ('root' not required)
- Database instances up and running (opened read/write required for AWR/Statspack)
- SYS credentials (hence the 'oracle' or dba user requirement)
Other Prerequisites
- Some free space in /tmp (or elsewhere, use --tempdir)
Installation
Downloading DBcollect
The latest release is always available on the releases page:
DBcollect releases (GitHub) On the Github releases page, go to the latest release, open Assets and download dbcollect.
DBCollect Download (application page, not always working) is a direct link to the latest version.
Easy Install
If your system has internet (https) access, see dbcollect install for an easy way to install dbcollect
Warning
- DBCollect location
- Do NOT put dbcollect in non-standard locations such as /tmp, /root etc. The user dbcollect runs as (usually oracle) needs to have access to the dbcollect file (hence it does not work in /root). It also may not work on mounted paths that have execute disabled (/tmp, /var/tmp, ...)
- Cloning Git Repository
- Do NOT clone the git repository and run it from there (it will result in an error). This to prevent tampering, and weird problems (the zipapp package ensures all required files are contained in a predictable location).
Other requirements
Linux
On Linux (EL7+) both Python 2 and 3 may be installed. To set the preferred version globally on the system, use alternatives
alternatives --set python /usr/bin/python3
AIX
On IBM AIX, you need to install Python first. You can get python for AIX from AIX Toolbox (IBM)
Make sure it is executable and available in $PATH.
Simply running python should work.
Solaris
On Solaris, Python should be already available. It may be an older version.
Make sure you can run python from the command line.
HP-UX
HP-UX has experimental support. Some OS commands require sudo access, run dbcollect --sudoers to install the sudoers file
before proceeding. This will allow dbcollect to pick up required stuff like CPU model, disk capacities and more.
sudo must be installed for this to work.
Windows
dbcollect does not yet support Windows. Let me know if you need it.
Python
The dbcollect app runs using a shebang (#!/usr/bin/env python). This means Python needs to be available in the environment to run dbcollect. Some systems do not have this by default.
On UNIX (AIX, Solaris) you may have to create a symbolic link or run dbcollect like this:
python3 /usr/local/bin/dbcollect
If all else fails, you can run dbcollect from python directly:
python /usr/local/bin/dbcollect
# or
/usr/bin/python /usr/local/bin/dbcollect
# or
python2 /usr/local/bin/dbcollect
