ptx®/CTC V1.1.5 Release Notes


Introduction

These release notes support Version 1.1.5 of the ptx®/CTC software intended for use with IBM® NUMA-Q and Symmetry® systems. ptx/CTC manages mission-critical applications during and after cluster transitions.

Read this document before you install or run this release of ptx/CTC.


Product Compatibility

This version of ptx/CTC can be used with the following systems:

ptx/CTC requires that the following products be installed on your system:


The ptx/CTC Database Location

The database must be accessible to all nodes in the cluster and should be stored on a raw shared ptx/SVM volume or a raw shared partition. It is strongly recommended that the database reside on a mirrored, shared ptx/SVM volume as a safeguard against disk failure. Each object in the database uses approximately 2,000 bytes of space. In general, the database should be large enough to hold the maximum number of objects in your configuration, plus room for future growth.


Software Installation

For installation instructions, refer to the DYNIX/ptx and Layered Products Software Installation Release Notes.

Note that ptx/CLUSTERS V2.1.4 or later must already be installed or must be installed at the same time as ptx/CTC V1.1.5.

Open Problems in ptx/CTC V1.1.5

This section lists open problems in this release of ptx/CTC:

229797
Two objects of type FS can be logged to the same /usr/ctc/logs file.

Workaround. Do not give two ptx/CTC objects the same name.

236166
ctcadm passes environment through to method. Subsequently, any methods that are run manually inherit a different environment than the environment that would exist during an availability transition.

Workaround. Since the ctcadm command is run as root, the root environment is inherited by ctcadm when performing operations such as start, stop, and verify. Perform failover tests manually with root environment by first typing su - root.

237168
ptx/CTC menus were not reinstalled after upgrading ptx/CLUSTERS.

Workaround. Always install ptx/CLUSTERS and ptx/CTC together. If you have already installed ptx/CLUSTERS, re-install ptx/CTC from the CD-ROM so that the menus will reappear.

241320
ctcd missing from /etc, giving error message, "Could not initialize, perhaps CTC_CONFIG_FILE not readable or database path not set."

Workaround. Stop ptx/CTC, set the database location, and then restart ptx/CTC. This procedure is described in the ptx/CTC Administration Guide, in the section titled "Creating Your ptx/CTC Configuration."
