Before Installation

QCCSID

Every message has a coded-character set identifier (CCSID) in its header. The CCSID tag identifies the code page and character set of the source. For CCSIDs that are supported on the AS/400 see the AS/400 National Language Support book.

The CCSID information is obtained, when a queue manager is created, from the job CCSID. If this does not contain a valid value in the range 1±65534, the information is obtained from the default CCSID value for the job.

Note: The CCSID must be either Single-byte character set (SBCS), or Mixed, that is SBCS and DBCS. It must not be DBCS only.

You can change the CCSID used by the MQSeries queue manager by using the CL command CHGMQM. See ªSetting the Queue Manager CCSID for MQSeries for AS/400º on page 43 for more information.

QUTCOFFSET

You should check that the coordinated universal time offset (QUTCOFFSET) system value has been set, to indicate the relationship between the system time and Greenwich Mean Time (GMT). You do this by working with the CHGSYSVAL command.

If QUTCOFFSET is not set, it takes the default value of zero. MQSeries for AS/400 then assumes that the local system time is universal time coordinated (UTC) - that is, GMT - and time stamps the MQSeries for AS/400 messages accordingly.

QSYSLIBL

Ensure that QSYS2 is included in the list of libraries that make up the system part of the library list.

MQSeries for AS/400 uses programs in this library for data conversion and SNA LU 6.2 communication.

QALWOBJRST

Ensure that the QALWOBJRST system value is set to *ALL or *ALWPGMADP before you install MQSeries for AS/400. If it is set to *NONE, the installation will fail.

After installation, reset QALWOBJRST to its original value to maintain system security.
