Necessary documentation

Before you call the IBM® Support Center, have the following information available:

Customer number: The authorization code that allows you to use the IBM Support Center. Your account name, your TCP/IP license number, and other customer identification should also be available.
Problem number: The problem number previously assigned to the problem. If this is your first call about the problem, the support center representative assigns a number to the problem.
Operating system: The operating system that controls the execution of programs (such as z/OS), include the release level.
Language Environment® runtime library: The release level of the link-edit runtime library is also needed if you are compiling user-written applications written in C or C++.
Component ID: A number that is used to search the database for information specific to TCP/IP. If you do not give this number to the support center representative, the amount of time taken to find a solution to your problem increases.
Release number: A number that uniquely identifies each TCP/IP release.

Table 1 lists the specific information that you should provide to the IBM Support Center.

Table 1. TCP/IP component name and release level
Component name and release level	System maintenance program	Field maintenance identifier/CLC
z/OS® Communications Server V2R1	SMP/E	The following identifiers are associated with this stack: HIP6210 (Communications Server IP) JIP621K (Communications Server Security Level 3) JIP621X (Communications Server X11R4 XWindows)

The following are component ID numbers for z/OS Communications Server:

Licensed IBM program: z/OS
Component ID number: 5650-ZOS

A complex problem might require you to talk to several people when you report your problem to the IBM Support Center. Therefore, you should keep all the information that you have gathered readily available. You might want to keep the items that are constantly required, such as the TCP/IP component ID, in a file for easy access.
