-----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Mark Jacobs Sent: Tuesday, May 22, 2012 9:56 AM To: [email protected] Subject: Re: XPLINK Modules in SCEERUN2 From the Ported Tools - OpenSSH Manual Setting up the XPLINK environment for use by IBM Ported Tools for z/OS: OpenSSH Description: Beginning in Version 1 Release 2, IBM Ported Tools for z/OS: OpenSSH is an XPLINK application. XPLINK (Extra Performance Linkage) is a type of call linkage that can improve performance in an environment of frequent calls between small functions. Is the migration action required? Yes, to ensure optimal performance. Steps to take: To set up the XPLINK environment (that is, to initialize the resources necessary to run an XPLINK application), take the following steps: * Put the Language Environment(r) run-time library SCEERUN2 in the LNKLST member of SYS1.PARMLIB. * Put the XPLINK modules in SCEERUN2 in the dynamic LPA. * Mark the run-time library SCEERUN2 as program controlled. I've verified that two of the three are done, can't find anything on the third.
