Plan your storage and performance requirements on Multiplatforms

We must set realistic and achievable storage, and performance goals for the IBM MQ system. Use the links to find out about factors that affect storage and performance on the platform.

The requirements vary depending on the systems that we are using IBM MQ on, and what components we want to use.

For the latest information about supported hardware and software environments, see System Requirements for IBM MQ.

IBM MQ stores queue manager data in the file system. Use the following links to find out about planning and configuring directory structures for use with IBM MQ:

• Plan file system support on Multiplatforms
• Requirements for shared file systems on Multiplatforms
• Sharing IBM MQ files on Multiplatforms
• Directory structure on UNIX and Linux systems
• Directory structure on Windows systems
• Directory structure on IBM i

Use the following links for information about system resources, shared memory, and process priority on UNIX and Linux:

• IBM MQ and UNIX System V IPC resources
• Shared memory on AIX
• IBM MQ and UNIX Process Priority

Use the following links for information about log files:

• Choose circular or linear logging on Multiplatforms
• Calculating the size of the log

• Disk space requirements on Multiplatforms
  The storage requirements for IBM MQ depend on which components you install, and how much working space we need.
• Plan file system support on Multiplatforms
  Queue manager data is stored in the file system. A queue manager makes use of file system locking to prevent multiple instances of a multi-instance queue manager being active at the same time.
• Choose circular or linear logging on Multiplatforms
  In IBM MQ, we can choose circular or linear logging. The following information gives you an overview of both types.
• Shared memory on AIX
  If certain application types fail to connect because of an AIX memory limitation, in most cases this can be resolved by setting the environment variable EXTSHM=ON.
• IBM MQ and UNIX System V IPC resources
  A queue manager uses some IPC resources. Use ipcs -a to find out what resources are being used.
• IBM MQ and UNIX Process Priority
  Good practices when setting process priority nice values.
