2012 z/OS Upgrades

 

01/02/2012

New Year's Day was Sunday, 01/01/2012. The Official University New Year Holiday was Monday, 01/02/2012. We provided minimal coverage in the 1155 E 60th Street Data Center consisting of one Computer Operator per 8-hour Shift to respond to System prompts, environmental alarms and telephone calls. The UCHIBETA LPAR was available for Open Testing on Monday, 01/02/2012, from 8:00 AM until 5:00 PM with its full complement of Online Regions. The Production Shop was not staffed on 01/02. ALSO, on Monday, 01/02/2012, we performed an IPL of the UCHIMVS1 (Production) LPAR at 6:00 AM.

01/05/12

During System Test Time on Thursday, 01/05/12, we began the process of increasing the size of the Mainframe Spool. We formatted a new Spool Volume and issued a "Drain" Command for the current Spool allowing it to be emptied during the next week. New Output will be directed to the new Spool Volume. We have scheduled System Test Time for Thursday, 01/12/12, to increase the size of the current Spool Volume once it has been emptied.

01/08/12

During System Test Time on Sunday, 01/08/2012, we expanded the range of OPS/MVS to support our future upgrade to ACF2 R15. OPS/MVS is an internal facility used by the Mainframe Systems Group to automate System responses. The UCHIBETA LPAR was available for Open Testing from 8:30 AM until 5:00 PM on Sunday, 1/8.

01/11/12

On Wednesday, 01/11/12, we made ACF2 Release 5 and maintenance to z/OS 1.12 available for Open Testing in the UCHIBETA LPAR. ACF2 R15 and z/OS 1.12 Maintenance will be needed for our future upgrade to z/OS 1.13. If Open Testing goes well, we will apply z/OS 1.12 maintenance and install ACF2 R15 in Production during System Test Time on Thursday, 01/26/12, from 6:00 until 7:30 AM.

01/12/12

During System Test Time on Thursday, 01/12/12, we continued the expansion of Spool space which was started on 1/5/12. We increased the size of the current Spool Volume which was set to "Drain" on 1/5. This in addition to the new Spool Volume installed on 1/5 will significantly increase overall Spool Space on the Mainframe.

01/16/12

Monday, 1/16/12, was the Martin Luther King Holiday. We provided minimal coverage in the 1155 Data Center consisting of one Computer Operator per 8-hour shift to respond to system prompts, environmental alarms, and telephone calls. The UCHIBETA LPAR was available for Open Testing from 8:00 AM until 5:00 PM with its full complement of Online Regions available. The Production Shop was not staffed on the Holiday. ALSO, on Monday, 01/16/12, we performed an IPL of the UCHIMVS1 LPAR at 6:00 AM.

01/23/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 01/23/12, at 6:00 AM.

01/26/12

During System Test Time on Thursday, 01/26/12, we installed ACF2 Release 15 and applied routine Maintenance to z/OS 1.12 in Production.  ACF2 R15 and z/OS 1.12 Maintenance will be needed for our future Operating System upgrade to z/OS 1.13; both ACF2 R15 and z/OS 1.12 Maintenance had been available for Open Testing in the UCHIBETA LPAR since Wednesday, 01/11/12.

01/30/12

02/01/12 

We made Release 5.0 of Xpediter/Xchange available for Open Testing in the UCHIBETA LPAR on Wednesday, 02/01/12, replacing Release 4.0 there. Xpediter/Xchange allows programmers to change the current date for batch or online processing in CICS.  We have tentatively scheduled Production installation of Xpediter/Xchange 5.0 for Wednesday, 2/15/12; we will not need System Test Time for this Production installation. Please email mfcticket@uchicago.edu to report problems with Xpediter/Xchange.

02/06/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 02/06/12, at 6:00 AM.

02/07/12

We removed Xpediter/Xchange 5.0 from the UCHIBETA LPAR on Tuesday, 02/07/12, and reverted to Xpediter/Xchange 4.0, while Compuware investigates a communication problem we have been experiencing with Release 5.0.

02/13/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 02/13/12, at 6:00 AM.

02/20/12

We performed an IPL of the UCHIMVS1 (Production) LPAR for Monday, 02/20/12, at 6:00 AM.  Also, on Monday, 2/20/12, we experienced a problem with communications between the Maingate Server (I-Trust application) and the Mainframe which the Systems Group is investigating.

02/23/12

Starting Thursday 02/23/12, we will use the UCHIBETA LPAR to test a work-around for the recent communication issue experienced between the Maingate Server (I-Trust application) and the Mainframe. Per Systems Group's Bob Cachur: the essence of the workaround is this:

  1. Continue to start the Policy Agent (PAGENT) using the autostart mechanism of the TCPIP stack.

  2. Move the task of starting the Internet Key Exchange Daemon (IKED) from the TCPIP stack to the auspices of OPS/MVS, our system automation tool.

This will ensure that PAGENT is up and running before the start of IKED. It is suspected that our problem yesterday was due to PAGENT not being available for IKED. I.e. they were initialized out of sequence during the Monday morning UCHIMVS1 IPL.

02/27/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 02/27/12, at 6:00 AM.

02/29/12

Bill Barkley and Compuware have resolved the communication problem encountered during Open Testing of Xediter/Xchange 5.0 in the UCHIBETA LPAR. On Tuesday, 02/07/12, we reverted to Release 4.0 of Xpediter/Xchange in BETA while the problem was investigated. We made Xpediter/Xchange 5.0 available for Open Testing in UCHIBETA on Wednesday, 02/29/12, replacing Release 4.0 there. Xpediter/Xchange allows programmers to change the current date for batch or online processing in CICS. Pending sucessful Open Testing in BETA, we will install Xpediter/Xchange 5.0 in Production during System Test Time on Sunday, 03/18/12, from 7:00 until 8:00 AM.

03/05/12

We performed an IPL of the UCHIMVS1 (Production) LAR on Monday, 03/05/12, at 6:00 AM. Effective with this IPL, the new procedure for establishing contact with the Maingate Server for the I-Trust Application during Mainframe IPLs went into Production. The procedure had been tested daily in the UCHIBETA LPAR since Thursday 02/23/12.

03/11/12

Daylight Saving Time began at 2:00 AM on Sunday, 03/11/12. The Mainframe continued to display Central Standard Time until we IPLed the UCHIMVS1 (Production) LPAR. We performed that IPL of UCHIMVS1 on Sunday, 03/11/12, at 6:30 AM Central Standard Time as shown on the Mainframe time display. This schedule allowed us time to complete all Production Backups before the IPL. Effective with this IPL, the Mainframe displays Daylight Saving Time (Spring Forward!). Any ESP Job Scheduler Events or Applications scheduled to run during the "missing" hour was run after the IPL.  The UCHIBETA LPAR was available for Open Testing starting at 8:10 AM CDT.

03/18/12

During System Test Time on Sunday, 03/18/12, we installed Xpediter/Xchange 5.0 in Production, replacing Release 4.0.

10/01/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 10/01/12, at 6:00 AM.

10/08/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 10/08/12, at 6:00 AM.

10/10/12

IT Services' Mainframe Systems Group had Exclusive Use of the UCHIBETA LPAR on Wednesday, 10/10/12, to test a process for making the File Transfer Protocol (FTP) available daily in BETA. We tested a method for defining specific IP Addresses as valid FTP targets in ACF2 and in the TCPIP NETACCESS control file in UCHIBETA. As UCHIBETA testing went well on 10/10, this new process will take effect in BETA on Thursday, 10/11/12, allowing us to make FTP available in BETA every day.

10/11/12

FTP has been enabled in the UCHIBETA LPAR as of Thursday, 10/11/12.  All external IP Adresses are "locked down" except for those defined in UCHIBETA by ACF2 and TCPIP NETACCESS control files.  This process was tested in UCHIBETA during the Mainframe Systems Group's Exclusive Use of BETA on Wednesday, 10/10/12.

10/15/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 10/15/12, at 6:00 AM.  ALSO, on Monday, 10/15, we had to "back out" the change which had enabled FTP in UCHIBETA on Thursday, 10/11, due to security concerns.  Additional testing of the ACF2 - NETACCESS process will be done during DCS' Exclusive Use of UCHIBETA on Thursday, 10/18/12.

10/17/12

There was a delay in making the UCHIBETA LPAR available for Open Testing on Wednesday, 10/17/12. A change we made to an ESP PARMLIB in BETA on Tuesday, 10/16, contained an invalid Keyword which prevented BETA from coming up cleanly on 10/17; once the Keyword was corrected, we successfully re-IPLed BETA and the LPAR was made available for Open Testing at 8:15 AM.

10/18/12

Data Center Services' Mainframe Systems Group had Exclusive Use of the UCHIBETA LPAR on Thursday, 10/18/12, to test ACF2 changes for NETACCESS authorization for use of FTP in that LPAR. No changes in current FTP restrictions in BETA resulted from this Exclusive Use.

10/22/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 10/22/12, at 6:00 AM.

10/25/12

Data Center Services' Mainframe Systems Group had Exclusive Use of the UCHIBETA LPAR on Thursday, 10/25/12, to activate NETACCESS Resource Rules in support of making FTP available every day in that LPAR. NETACCESS had been made available in BETA effective 10/11 but was removed on 10/15 due to security concerns over certain batch LoginIDs having "high end" ACF2 privileges which allowed them to bypass NETACCESS rules. During DCS' Exclusive Use of BETA on 10/18, we successfully tested a process for removing those unnecessary privileges allowing NETACCESS to work as intended. Based on the success of the testing done in BETA on 10/25, we will enable FTP in BETA on Tuesday, 10/30. On 10/25, we also tested a new "Resolver" configuration for DNS lookups in UCHIBETA.

10/29/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 10/29/12, at 6:00 AM.

10/30/12

Based on the success of the testing which was done in UCHIBETA during DCS Exclusive Use on Thursday, 10/25/12, we have enabled FTP in BETA on Tuesday, 10/30. Effective on that date, all external IP Addresses are "locked down" except for those defined in BETA's ACF2 and NETACCESS control files.

11/04/12

Daylight Saving Time ended on Sunday, 11/04/12, at 2:00 AM (Fall Back!). In order to revert to Standard Time on the IBM z9 Mainframe, we needed to perform an IPL of the system. Until that IPL, the Mainframe continued to display Daylight Saving Time. We performed that IPL of the UCHIMVS1 (Production) LPAR on Sunday, 11/04/12, at 7:00 AM "DST." That schedule allowed time for the Weekly Offsite DASD Backups to complete. Effective with that IPL, the Mainframe now displays Central Standard Time.

11/12/12

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 11/12/12, at 6:00 AM.
