========================================================== Maintenance for IBM Sterling Connect:Direct for UNIX 4.3.0 ========================================================== This maintenance archive includes module replacements for the C:D UNIX 4.3.0 code base. It is applicable to C:D UNIX version 4.3.0, and contains all the new functionality and fixes as described in the C:D UNIX 4.3.0 Release notes, as well as fixes for the issues listed below. This release implements IBM's standard V.R.M.F method of identifying software. V, R, M and F are Version, Release, Modification and Fix Pack respectively. In general, V.R.M imply new functionality, while F is an accumulation of fixes called a Fix Pack. The term Fix Pack will be used going forward in place of Cumulative Maintenance. Individual fixes also have a new name, Interim Fixes, or iFixes for short. iFixes are numbered sequentially from one starting with any increment to V, R, M or F. Please see IBM's website for further details regarding this methodology. After applying the maintenance, the CLI banner will report that your C:D version is 4.3.0.x, where x is the current Fix Pack. It will also display the date that the maintenance was created. For more information, please refer to the C:D UNIX 4.3.0 Release Notes. ================================================= iFixes listed below apply to C:D for UNIX 4.3.0.0 ================================================= 001) RTC523522 / APAR IT18957 commit date: 26 Apr 2018 -------------------------------------------------------- In rare circumstances, a text file sent to a destination file with fixed block record format on z/OS may be padded with ASCII blanks instead of EBCDIC. 002) RTC552947 / APAR IT24014 commit date: 30 Apr 2018 -------------------------------------------------------- When Secure+ security mode is disabled, session establishment can be expected to take less time than when a security mode, FIPS 140-2, for example, is enabled. However, session establishment with security mode disabled takes the same amount of time as when enabled. Session establishment times may also be increased if cdpmgr inherits a large maximum file descriptor system resource limit. 003) RTC564598 / APAR IT25140 commit date: 24 May 2018 -------------------------------------------------------- Incoming Secure+ session incorrectly allowed when the .Local node has Secure+ enabled and there is no Secure+ entry for the remote node. 004) RTC561582 / APAR IT24339 commit date: 25 May 2018 -------------------------------------------------------- Copy send performance to C:D Z/OS can be degraded when the UNIX source file sysopts includes "datatype=binary", and the Z/OS destination file record format is VB or FB. 005) RTC561515 commit date: 22 June 2018 ------------------------------------------ When alt.comm.outbound is configured on a remote node, traverse the alt.comm.outbound list on each process retry until we have a successful connection to the remote node. 006) RTC568699 commit date: 05 July 2018 ------------------------------------------ Customization fails with a syntax error during installation of C:D UNIX 4.3 on Solaris. 007) MFT-9886 commit date: 15 Aug 2018 ---------------------------------------- Connect:Direct for UNIX Secure+ uses IBM Java Runtime, which is vulnerable to the following issue: CVE-2018-2602: An unspecified vulnerability related to the Java SE I18n component could allow an unauthenticated attacker to cause low confidentiality impact, low integrity impact, and low availability impact. 008) MFT-9824 commit date: 16 Aug 2018 ---------------------------------------- A process may terminate abruptly with statistics reporting "SMGR terminated by signal". A known manifestation of this issue is likely to occur when a run job on a C:D z/OS node is attempted. 009) RTC562386 / APAR IT24362 commit date: 04 Sep 2018 -------------------------------------------------------- Parser error XPAE003I may be generated when submitting a process that has an snodeid coded with a 'Y' or 'N' character for the password. 010) RTC565352 / APAR IT24904 commit date: 04 Sep 2018 -------------------------------------------------------- There are three possible issues that may occur when sending a text file a to a z/OS destination that uses VB format with LRECL=BLKSIZE+4: . If the first record is within four bytes of the block size, the transfer will fail with an SVSJ045I message. . If the first record is four bytes or more smaller than the block size, and a subsequent record fills an entire block exactly, the z/OS destination file will be corrupted. . If the first record is four bytes or more smaller than the block size, and a subsequent record is up to four bytes longer than the maximum record size, this error condition will not be detected, and the z/OS destination file will be corrupted. 011) RTC567101 / APAR IT24905 commit date: 04 Sep 2018 -------------------------------------------------------- When sending a file to C:D z/OS and specifying the SYSOUT SYSOPTS parameter, CDU may inappropriately set the destination record format (RECFM) to VB. 012) RTC564088 / APAR IT25329 commit date: 04 Sep 2018 -------------------------------------------------------- If a process is submitted that runs a job or task on a node with a pmgr trace running, anything written to stdout by the job or task may also appear in the pmgr trace output. This might occur even after the pmgr trace is turned back off. 013) RTC565959 commit date: 04 Sep 2018 ----------------------------------------- In some circumstances, an attempt to update the .Local node record via the Secure+ Admin Tool will fail reporting something similar to "Error #6 - Remote Node file not found." 014) RTC566602 / MFT-9446 / APAR IT26480 commit date: 04 Sep 2018 ------------------------------------------------------------------- On AIX systems, C:D UNIX executables will inappropriately prefer run time libraries in /usr/vac/lib and /usr/vacpp/lib directories instead of the standard /usr/lib /lib directories. The /usr/vac/lib and /usr/vacpp/lib directories may be populated if an IBM compiler is installed on the system, for example. If the libraries in /usr/vac/lib and /usr/vacpp/lib are old or otherwise incompatible with the C:D UNIX executables, various errors may occur, including XSMG609I, SMGR (pnode) failed to convert FMH68 to network format. 015) RTC571051 commit date: 04 Sep 2018 ----------------------------------------- In rare circumstances, a process may fail to start, reporting an XSCM006E error, all users are denied access to CD from the SACL, even though the Strong Access Control (SACL) directory and file appear to have correct ownership and permissions set.

Also, the direct CLI output of a detailed select statistics command may include a message id and a Short Text description of the message. The Short Text description might be truncated if the text is very long. Note: It's remotely possible that a restarted process may fail on the snode side with an XSMG235I or XSMG239I message that refers to a file ending with .savedCTRstatLog. This indicates that there may be a copy step of the indicated process that is missing its CTRC record on the snode side. If user investigates and determines the CTRC record is logged, or is not necessary, then they may get past these errors by removing the indicated file that ends with .savedCTRstatLog and then releasing the process again. 045) CDUA-1529 commit date: 21 Jun 2019 ----------------------------------------- Cfgcheck does not accept more than one file.ioexit entry in initparm.cfg 046) MFT-10416 commit date: 03 Jul 2019 ----------------------------------------- On some systems, cdpmgr may fail to start, reporting an XRIA010I message. cfgcheck may also report the same error attempting to validate configuration files. 047) MFT-10398 / APAR IT29723 commit date: 15 Jul 2019 -------------------------------------------------------- A CD Plex redirection is logged with SCPA007I, RC=8.
