05/01/06

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, May Day, 5/01/06, at 6:00 AM. No proletariat were exploited in creating this message.

05/02/06

A problem with the Mainframe’s Hardware Management Console delayed availability of the UCHIBETA LPAR until 9:15 AM on Tuesday, 5/2/06. IBM was notified of the problem and worked with our Mainframe Systems Group to reboot the HMC.

05/29/06

We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 5/29/06, at 6:00 AM.

05/31/06

During System Test Time on Wednesday, 5/31/06, we renewed the SSL Certificate needed for Mainframe FTP and tn3270. You may need to change the Session Options in your HostExplorer to be able to connect to the Mainframe via tn3270. (Please NOTE that if you have been able to access the UCHIBETA LPAR since Tuesday, 5/23, you should not need to make any changes at this time.) If you have upgraded to HostExplorer 2006, available from NSIT’s Site Licensing web site, or if you are running HostExplorer 9.0.0.0, or HostExplorer 8.0.0.3, please follow these instructions:

In HostExplorer 9.0, Open your session options and click on Security and then SSL/TLS. If there is a checkmark next to “Accept Unverified Server Certificates”, you will not have any problems connecting using the new mainframe certificate (currently on uchibeta and as of 5/31/06, on uchimvs1). If it is unchecked, you will not work.

In HostExplorer 2006 (aka 11.0), Open your session options and click on Security and then SSL/TLS. If there is not a checkmark next to “Verify Server Certificate”, you will not have any problems connecting using the new mainframe certificate (currently on uchibeta and as of 5/31/06, on uchimvs1). If it is checked, you will not work.

In HostExplorer 8.0.0.3, Open your session options and click on Security and then SSL/TLS. If there is a checkmark next to “Close Connection if Negotiation Fails”, you will have problems connecting using the new mainframe certificate (currently on uchibeta and on uchimvs1 as of 5/31/06). If it is unchecked, you will work.
To see which version of HostExplorer you are running, open a Mainframe session, open the pull-down menu under “HELP” and select “? About…” to display an information panel containing the version number. If you are running HostExplorer 8.0.0.0 or HostExplorer 9.0.0.22, you should not need to upgrade. Unfortunately, an upgrade to HostExplorer 2006 will not carry over any special function key definitions (F1, F2, etc) and you will need to reprogram those for your keyboard. Desktop Support will be upgrading the leased machines under their care. Call 4-TECH (4-8324) for assistance if needed.

When launching Mainframe FTP, you will be presented with a dialog box titled “Non-Trusted Certificate”. This box contains certificate attribute information and has three radio buttons to select from: “Allow this connection only”; “Trust this certificate”; and “Do not allow this connection”. For those who always select “Allow this connection only”, the only difference to be seen will be updated attributes in the Certificate Information field. For those who had previously selected “Trust this certificate” before the upgrade on 5/31, this will be the first time to see this dialog since the first time FTP was launched after the last certificate renewal in September, 2003. Selecting “Trust this certificate” means you will not see this dialog box again until the next certificate renewal in March, 2009.
06/05/06 We performed an IPL of the UCHIMVS1 (Production) LPAR on Monday, 06/05/06, at 6:00 AM.
06/08/06 During System Test Time on Thursday, 06/08/06, we installed the backup Virtual Tape appliance and configured the new DASD Array on the Mainframe.
06/12/06 During System Test Time on Monday, 6/12/06, we made SAS 9.1.3 the Mainframe Production default replacing SAS 8.0.2 in the UCHIMVS1 (Production) LPAR. SAS 9.1.3 had been available for testing in both the UCHIBETA and UCHIMVS1 LPARs since 10/27/05, and has been the default in BETA since 4/17/06. We have also applied Service Pack 3 to SAS 9.1.3. Neither SAS-ETS nor SAS-CONNECT have been activated in SAS 9.1.3.

ALSO, on Monday, 6/26/06, we connected the new Mainframe disk array, the IBM DS6800, to the UCHIBETA LPAR for one day of Open Testing. No volume names were changed; no JCL changes were needed. Online Region procedures (access, update, inquiry, etc) were tested during the morning while the Data Center tested backups and restores on non-public volumes. In the afternoon, batch processing was tested after Onlines were taken down. Jobstreams could be scheduled with ProdShop or run by end users. One DP100 Printer and any 3480 drives needed for testing were atttached to BETA for the day (but, of course, UCHIMVS1 took priority for resource allocation). Please NOTE that the TRNSFR Volume was not available on BETA during this Open Test: Data transfers from BETA to UCHIMVS1 were not possible because the DS6800 was not available on UCHIMVS1. ALSO, due to the fact that we needed to back out the DS6800 from UCHIBETA following Open Testing, we did not extend UCHIBETA past 5:00 PM.

06/27/06

SAS 9.1.3 Service Pack 4 was made available for testing in both the UCHIMVS1 and UCHIBETA LPARs. SAS 9.1.3 SP3 remained the default version in both LPARs.
