Support
Like all other versions of Linux, Linux on System z is governed by the GPL free software license. Complete Linux on System z source code is available from numerous groups on a free and equal basis, and architectural support is now part of the main Linux kernel effort. IBM assigns several of its programmers to the community effort, but IBM is by no means the only participant.
Most Linux on System z customers, particularly those with business-critical production workloads, purchase a software support contract from commercial Linux vendors such as SUSE or Red Hat. IBM Global Services also offers support contracts, including 24x7 coverage. Some standard Linux software applications are readily available pre-compiled, including popular closed-source enterprise software packages such as WebSphere, DB2 and Oracle databases and applications, SAP R/3, and IBM's Java Developer's Kit (JDK), to name only a few. Nearly every free or open-source software package available for Linux generally is available for Linux on System z, including Apache HTTP Server, Samba software, JBoss, PostgreSQL, MySQL, PHP, Python programming language, Concurrent Versions System (CVS), GNU Compiler Collection (GCC), and Perl, among many others.

Famous quotes containing the word support:
“Every winter the liquid and trembling surface of the pond, which was so sensitive to every breath, and reflected every light and shadow, becomes solid to the depth of a foot or a foot and a half, so that it will support the heaviest teams, and perchance the snow covers it to an equal depth, and it is not to be distinguished from any level field. Like the marmots in the surrounding hills, it closes its eyelids and becomes dormant for three months or more.”
—Henry David Thoreau (1817–1862)
“Because the young child feels with such intensity, he experiences sorrows that seem inconsolable and losses that feel unbearable. A precious toy gets broken or a good-bye cannot be endured. When this happens, words like “sad” or “disappointed” seem a travesty because they cannot possibly capture the enormity of the child’s loss. He needs a loving adult presence to support him in his pain but he does not want to be talked out of it.”
—Alicia F. Lieberman (20th century)
“Three factors—the belief that child care is female work, the failure of ex-husbands to support their children, and higher male wages at work—have taken the economic rug from under that half of married women who divorce.”
—Arlie Hochschild (20th century)
