Hi, I’m having an issue with database queries in one of my applications since migrating to Rocket PHP. When running the below code, I used to get a record from the DB2 table split into the $subject, $authorname, $authorid, and $message variables; but now I’m getting NULL for each one. Here is the code that is experiencing the issue: $query = "SELECT SUBJECT,AUTHOR,USERID,BODY FROM $_SESSION[DATABASE] WHERE NUMBER=$tm"; putenv("DSNAOINI=$_SESSION[DB2INI]"); $dbh = new PDO($_SESSION['DB2SSID'],$_SESSION['APPID'],$_SESSION['APPPW'],array('PDO_ATTR_PERSISTENT' => false)); $dbh->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION); $sth=$dbh->prepare($query); $sth->execute(); $sth->bindColumn(1,$subject); $sth->bindColumn(2,$authorname); $sth->bindColumn(3,$authorid); $sth->bindColumn(4,$message); $sth->fetch(PDO::FETCH_BOUND); $sth = NULL; $dbh = NULL; I’ve tried using the actual column names instead of binding them by number and that didn’t help. I also tr

We are running z/OS V2 R1 and in preparation for going to V2 R2, I am installing the Perl distribution from Rocket’s Open Source Tools site. My first foray into testing resulted in: CEE3559S External variable PL_op_mutex was not found in DLL libperl.so. The traceback information could not be determined. [1] + Done(137) ./genConfigFile.pl rkmadm asdfasdf 50397899 Killed ./genConfigFile.pl I’ve not had any luck searching on the LE message CEE3559S.

I’ve just installed the OpenSSL tool and am running a BPXBATCH job to display the version information using the following command: openssl version It works, in that it displays this message: OpenSSL 1.0.2h 3 May 2016 however on the next line it also produces this message: WARNING: can’t open config file: /rsusr/rocket/ssl/openssl.cnf In my case the tool is installed into a directory called /usr/local/Rocket/ported/openssl I can’t work out why the version command is trying to open /rsusr/rocket/ssl (which doesn’t exist on my system) Any ideas what I have done wrong or haven’t done?

Status: DeclinedPopulate PDSTGTBL when processing S1 function, development driven stage like-other.When building JCL for CA JCLCheck validation of like other (JCL components) it would be helpful to be able to access a list of other JCL components in the same and participating packages.  The CA JCLCheck remote validation requires creation of a control statement [SSPROC dsn(member)],.  PDSTGTBL provides this information when staging from the package member list (S2, package drivenstage like-other) but during S1, development driven stage like-other, processing the table is not available and contains unrelated information.

We’re currently running PHP version 5.4.4 build 0003 on z/OS V2R2. When running a simple php -v or php -help command we receive S0CC abend (HFP-Exponent-Overflow Exception). This problem occurs in one of our Test LPARs but we’re not seeing the issue on another one of our test LPARs. Could this problem be related to a specific LE Option? What can we do to further troubleshoot this issue?

Implemented perl 5.16.2 as part of z/OS 2.2 migration. A critical perl user was not able to run existing code with 5.16.2 but it works with 5.8.7. Here’s our test case: 5.8.7: #!/usr/lpp/perl #####!/usr/bin/perl open( RESPONSE_BASE, “<:encoding(ISO8859-1)”, “/u/snomre/weekly_tdi/kmbtstorig.txt” ); open( RESPONSE_MOD, “>:encoding(ISO8859-1)”, “/tmp/kmbtst.txt” ); while (<RESPONSE_BASE>) { chomp; print( “before substitution $_\\n” ); s/( ¬# \\s*)HELLO=.*/$1HELLO=Melissa/; print( RESPONSE_MOD “$_\\n” ); } close(RESPONSE_BASE); close(RESPONSE_MOD); 5.16.2 #!/usr/bin/perl open( RESPONSE_BASE, “<:encoding(ISO8859-1)”, “/u/snomre/weekly_tdi/kmbtstorig.txt” ); open( RESPONSE_MOD, “>:encoding(ISO8859-1)”, “/tmp/kmbtst.txt” ); while (<RESPONSE_BASE>) { chomp; print( “before substitution $_\\n” ); s/( ¬# \\s*)HELLO=.*/$1HELLO=Melissa/; print( RESPONSE_MOD “$_\\n” ); } close(RESPONSE_BASE); close(RESPONSE_MOD); Expected response in 5.8.7: before substitution # HELLO=abc

I am sure that most ZMF customers can appreciate that it has been a reasonably busy week or so here in Serena ‘ZMF land’. We therefore thought it fitting to recap events and provide a couple of updates that all customers who already have moved, or who intend to move, to ZMF 8.1.1 need to know.       ZMF 8.1.1 Essential Maintenance Every ZMF customer reading this article should now be aware of the ‘Essential Maintenance’ alert that was issued in relation to DEF284711.  If not, please familiarise yourself with the following article (you will need to be logged into the Serena Support website to access this link):http://knowledgebase.serena.com/InfoCenter/index?page=content&id=S141693&token=a0dd0414590c455ca7e9ea082e8d90ca We cannot overstate the importance of applying this maintenance to your 8.1.1 software prior to upgrade of your ‘live’ ZMF systems.  The reality of this problem is that you are highly likely to lose data if you move ahead with Z

I’m testing php 5.4.4 to replace the ibm ported php 5.1.2 under IBM HTTP server 8.5.5.9. with the IBM ported php, i have a cgi called php, which is a shell script that then executes the php cgi program, with the php script name from the url. With php 5.1.2, I can run a php script that does the print phpinfo() and I get the proper html page back. When i change my php shell script to use the 5.4.4 php_cgi, I don’t get any output back. Instead I get a 404 error page in my browser, but neither the web or php error logs show any problem. Have you run into this issue? What do I need to do in order to get this working with the 5.4.4? Thanks, Peter

All z/OpenSource languages and tools have in common the existence of a file named README.ZOS containing instructions and example commands for installation of the tool. This file is located in : share/doc/<toolName>/<version>/ There are also instructions for unpacking.

Hi, I’ve been working with the z/OS Open Source version of PHP and found a behavior that is different then the previous version we’ve used. We commonly use PHP scripts to parse through the results of system commands at our shop for system checking and monitoring. One such example is a script that checks the available space in file systems. We’ll do something like this: $dfcmd = “df -kP" exec(”$dfcmd",$dfout,$dfrc); foreach ($dfout as $df) { #Check each filesystem } In the previous version of PHP the results from the command would result in $dfout being populated as an array with each output line as a separate array element. This allowed the following foreach loop to parse through the results. In the new version, $dfout is instead populated with a long string with the EOL characters included. Is this the desired behavior? Thanks!

The version of a distribution is often not enough for uniquely identifying it for purposes of knowing whether or not you have the most up-to-date code. Sometimes, for the same tool version, Rocket will make available for download multiple iterations each with a different build number. When requesting support for a language or tool from Rocket be sure to include the name, version, and build number. The build number is part of the original distribution file you downloaded from Rocket. Also, in the unpacked distribution you will find a VERSION.ZOS file that contains this information within this sub-folder: share/doc/<toolName>/<version> (e.g. share/doc/bash/4.3) It is best to keep this file so you can uniquely identify your tool version.

As we approach the release date for ChangeMan ZMF 8.1.1,  here is a screen print of a complete list of the HLLX Exits available in this new release..    We would like to solicit input from the user base as to what HLLX exits should be considered next for inclusion in the product.  One area that we feel should be looked at is ERO and we would like to get feedback on that.  #ChangeManZMF#Announcement

I'm trying to create a Java App to approve a CMN ZMF Package without requiring users to logon to the mainframe and into CMN ZMF etc.... I was able to get the 'Sample' Webservices Java app (provided via the support site) to work. However, when I attempt to code the approval process/service (i.e. PackageLifeCycle.ApprovePackageRequest) I'm getting some odd errors in the Java code (i.e. fields don't appear to be defined correctly) and I can't even get to a test phase. Is there anyone out there that has successfully done this. If so, would you be willing to provide a sample similar to the 'Package Information' Sample provided by Serena? Thanks.#ChangeManZMF

Status: DeliveredIncluded in ZMF 8.3Since users may use different package create methods (long, short....) and some of these skip panels, update the first package create HLLX exist(s) to be able to set values for panels that may not be displayed and thus skipping HLLX processesing that may be required.Since users may use different package create methods (long, short....) and some of these skip panels update the first package create HLLX exist to be able to set values for panels that may not be displayed and thus skipping HLLX processesing that may be required. Example for simple package we use MANUAL for install and require that INSTALL date be 3 moonths from current date of package create to give time to code, test before baseline without passing install date.  Depending on method for package create other than LONG HLLX can not set standards required. I would like to see if the first HLLX exit(s) used for package create can set the values for other panels that may not be processed but

Welcome to the Rocket z/OS Open Source Languages and Tools forum. This is a place where you can ask questions about our open source languages and tools and get answers from other mainframe professionals like yourself, as well as members of the Rocket team.

Has anyone experienced a higher than normal amount of bugs in ZMF V713C? We have had to implement no less than 5 vendor fixes or workarounds to resolve issues.#ChangeManZMF

Status: Already OfferedThis function is already available via the component browse apiAdd a new REST method to the ZMF Package Services that enables the browsing of the actual content of a package component to the REST services. In the old TT4ZMF integration, this functionality was available. It was used so that peers or dev leads could do peer code review of packages/components and then approve all from SBM. Functionality was lost when moving to ZMF Package Services.
