Troubleshooting installation and startup of Zowe z/OS components

Troubleshooting installation and startup of Zowe z/OS components

The following topics contain information that can help you troubleshoot problems when you encounter unexpected behavior installing Zowe z/OS components or starting Zowe's ZWESVSTC started task.

Unable to create BPXAS instances#

Symptom:

When you start ZWESVSTC started task, either by running the zowe-start.sh script or by launching the started task directly, you encounter the following error in the log:

<ROOT_DIR>/bin/internal/run-zowe.sh 1: FSUM7726 cannot fork: reason code  = 094500f7: EDC5112I Resource temporarily unavailable.

You will also encounter the following messages in the SYSLOG:

Solution:

This problem occurs when the maximum number of BPXAS instances have been reached.

This may be because when the Zowe instance directory was created, it was generated in the same location as the Zowe root directory. The Zowe instance directory is created by using the script <ROOT_DIR>/bin/zowe-configure-instance.sh -c <PATH_TO_INSTANCE_DIR>. See Creating an instance directory. The Zowe runtime directory is replaced when new PTFs are applied and should be considered as a read-only set of files. Zowe instance directories are designed to live outside the directory structure and are used to start a Zowe runtime.

This problem will only occur with Zowe drivers prior to v1.10 and has been resolved in v1.10 where the zowe-configure-instance.sh script will report error if it detects the -c argument because the installation directory location is an existing Zowe runtime directory.

Errors caused when running the Zowe desktop with node 8.16.1#

Symptom:

When you start the ZWESVSTC started task, you encounter the following error messages:

/usr/lpp/zowe/components/app-server/share/zlux-app-server/lib/initInstance.js:1(function (exports, require, module, __filename, __dirname) {SyntaxError: Invalid or unexpected token    at createScript (vm.js:80:10)    at Object.runInThisContext (vm.js:139:10)    at Module._compile (module.js:617:28)    at Object.Module._extensions..js (module.js:664:10)    at Module.load (module.js:566:32)    at tryModuleLoad (module.js:506:12)    at Function.Module._load (module.js:498:3)    at Function.Module.runMain (module.js:694:10)    at startup (bootstrap_node.js:204:16)    at bootstrap_node.js:625:3
/global/zowe/instances/prod/bin/internal/run-zowe.sh 3: FSUM7332 syntax error: got ), expecting Newline

Solution:

This problem occurs when you use Node.js v8.16.1 which is not supported on Zowe. There is a known issue with node.js v8.16.1 and Zowe desktop encoding. Use a supported version of Node.js instead. For more information, see Supported Node.js versions.

Cannot start Zowe and UNIX commands not found with FSUM7351#

Symptom:

When you start the ZWESVSTC started task, you might encounter the following error message:

dirname: <instance-dir>/bin/internal/run-zowe.sh 2: FSUM7351 not foundpwd: <instance-dir>/bin/internal/run-zowe.sh 2: FSUM7351 not found.: <instance-dir>/bin/internal/run-zowe.sh 3: /bin/internal/read-instance.sh: not found

Solution:

Check that /bin is part on your PATH. Do echo $PATH to check. If it is missing, make sure that it is appended to PATH in your profile, for example, in /etc/profile/.
