Installing a PSC

Before installing a PSC:

• Determine the site name
• Determine the site link costs for the links to other sites

To install a PSC you need to know:

• The size of the MQIS database on the PEC
• The names of the CNs that the PSC will join
• The computer name of the PEC

If you install the PSC from an MSMQ installation share on the PEC, you do not need the computer name of the PEC. For more information on installing MSMQ from an installation share, see "Installing MSMQ from Installation Shares" earlier in this chapter.

The PEC must be online when you install a PSC.

In addition to MSMQ access permissions required to install PSC, you must also belong to the Administrator group on the PEC computer.

Note When you install a PSC, the MQIS database is copied from the PEC. Queues cannot be created on computers in the PEC's site while the database is being copied. To avoid this situation when MQIS activity on the PEC MQIS is high, or the link between the PSC and PEC is slow, install the PSC from an installation share on a BSC in the PEC site.

For more information on MSMQ access permissions, see "Access Control" in Chapter 5, "Securing MSMQ."

1. Run Setup from the MSMQ\Server folder on the Windows NT Server, Enterprise Edition 4.0 Components CD, or from a shared MSMQ installation folder (typically shared as MSMQInst).
Note You cannot install the limited version of SQL Server 6.5 when you install an MSMQ controller server from an installation share.
2. Click Continue.
3. Confirm the default installation folder, or click Change Folder to select a new one.
4. Click Server, Installation Server, or Custom.
• When you click Server, Setup installs the MSMQ software and the MSMQ administration tools.
When you click Installation Server, Setup installs the MSMQ software and creates an installation share. The installation share contains installation files for computers running Windows 95 and Windows NT on Intel-compatible computers. When you click Custom, you select specific MSMQ components. You can specify alternate folders for the MSMQ SDK, administration tools, and installation share. You can also specify which platforms will be supported by selecting Installation Share and clicking Change Option. With Custom installation, support for computers running Windows 95 and Windows NT (x86 and Alpha platforms) is selected by default.
5. Click Primary Site Controller and then click OK.
6. If either the MSDTC or the MSSQLServer service is running, the Stop Running Services? dialog box appears. Click Yes to continue installing MSMQ. if it is unacceptable to stop these services, click No and install MSMQ later. Setup restarts these services after reinstalling MSMQ.
6. specify the Data Device and Log Device location and size.
The data and log devices on a PSC should be the same size as the data and log devices on the PEC. 8. Specify the computer name of the PEC. The installation server computer name is provided by default if you are installing MSMQ from a shared installation folder. 9. Specify the Site Name. The site name can be 31 characters long, and can contain any characters.
7. Specify the site link costs to the other sites in the enterprise and then click Continue.
Site links and site link costs are used by MSMQ to determine the available routing paths, and the cost of routing between sites. For more information on determining site link costs, see "Basic MSMQ Concepts," and "MSMQ Routing," in Chapter 1, "Understanding MSMQ."
8. If necessary, pair your network adapter card addresses to the correct CNs. When you're done, click Continue.
Setup prompts you for this information only if:
• You have two network adapter cards on the same protocol (for example, you have two network adapter cardsusing IP) and at least one CN exists for that protocol.
• Two or more CNs match the protocol being used by at least one of your installed network adapter cards(for example, two IPX CNs exist and you have one network adapter cardusing IPX).
Note MSMQ servers that connect to other MSMQ servers through a RAS link should not support the NetBEUI protocol over RAS. RAS support for NetBEUI is disabled by default. To view your RAS protocol settings, run Control Panel, double-click Network, click the Services tab, click Remote Access Service, click Properties, click the appropriate modem, and then click Network.
