Oops, one of the CICS data tables in our system filled up, and, unfortunately, the application did not report the NOSPACE condition or even abend when it ran into the problem. So, I guess that makes it the system programmer’s responsibility to detect. (That was a bit of sarcasm.) Can we detect this condition with… Read More »
The Problem Faced with the prospect of updating IBM Data Server Clients (DB2 Drivers) because a current release is going out of support, how do I manage the scope of the upgrade? A lot of servers and desktops of various operating systems have lots of different levels and types of DB2 client installed. An automated… Read More »
In an earlier post, I used regexec() to validate an email address format and found that regexec() does not support non-capture groups. Well, I didn’t really need them, but let’s see if we can get this support by using the Standard C++ Library <regex> template function which does support non-capture groups which is part of… Read More »
Faced with the requirement to edit for a valid email address format from a CICS application, one developer was using the java regular expression support which necessitated starting up a JVM Server in multiple CICS regions at about 90MB of storage per region. I think the developer must have gotten the regular expression to use… Read More »
This post combines information from earlier posts including, Writing a Rexx Function in C Updated RxRandom External Rexx Function (in C) RxRandom Revisited — Metal C Catalog Search (IGGCSI00) From COBOL Processing a GDG in Any Order Using IGGCSI00 in COBOL Now we will build a Rexx function in C (Metal C) that uses the… Read More »
Building on earlier articles COBOL POSIX Sockets, COBOL SSL Sockets and Consuming an XML service with COBOL, we want to enhance our project to handle multiple requests to the XML service, to better handle some errors and HTTP chunking. Objectives, Handle multiple requests read in from SYSIN. Process the requests over a single connection to… Read More »
Now that we can make HTTP web requests directly from our COBOL program and do this with SSL Security, we should be able to use these skills access a service that returns non-SOAP XML. JSON is preferable these days, however we can leverage the native COBOL parsing support for XML and, as far as I… Read More »
In an earlier post I discussed generating translate tables using CDRA and promised that I might cover doing the same using Unicode Services. Well, here is the update. In many respects, using the Unicode Services character conversion routine CUNLCNV is quite a bit simpler than the CDRA interface. cunitbl.c The header is in SYS1.SCUNHF so… Read More »
In an earlier post, I discussed compiling java programs for CICS using a batch job. Unfortunately, starting with CICS TS 5.1 (or in CICS TS 4.2 using a JVM Server), this no longer works. CICS TS 5.1 did away with the JVM Pool structure and any java applications you have need to be repackaged in… Read More »
The MH05 SupportPac reads or browses the MQ EVENT queues, formats and prints the messages and, optionally, emails them. The SupportPac information is here: MH05 There aren’t good instructions included on how to run this on z/OS, although it is supported. This is what I did: Put these files into a directory. com.ibm.xmq.events-1.6.jar javax.mail.jar mail.config… Read More »
