> # Starting the SequeLink® Manager for z/OS

> 1. Start the SequeLink Manager for z/OS. How you start the SequeLink Manager for z/OS depends on whether you allocated the SequeLink ISPF libraries to the TSO session (refer to the SequeLink Installation Guide).
> - If you allocated the ISPF libraries, continue with Step 2.
> - If you did not allocate the ISPF libraries, continue with Step 3.
> 2. Starting the SequeLink Manager When ISPF Libraries Are Allocated:

> Type the following command:

> TSO %SSMC [HLQ(HLQ_prefix) USR(USR_prefix)]

> where HLQ_prefix is the installation dataset prefix, and USR_prefix is the server-specific dataset prefix. Then, press ENTER. When using this format to start the SequeLink Manager for z/OS, you must always pass the HLQ parameter. We recommend passing the USR parameter as well. If you do not specify the USR parameter, SequeLink retrieves the last passed value from your SSMC profile. If neither parameter is passed, and no value can be retrieved from your profile, the default value HLQ is used.

> For example:

> `TSO %SSMC HLQ(SQLNK.V6R0M0) USR(COMPANY.DEV)`

> 3. Starting the SequeLink Manager When ISPF Libraries Are Not Allocated:

> Type the following command:

> TSO EX '`HLQ_prefix`.CLIST(SSMC)' '[HLQ(HLQ_prefix)] [USR(USR_prefix)]'

> where HLQ_prefix is the installation dataset prefix, and USR_prefix is the server-specific dataset prefix. Then, press ENTER. You do not have to explicitly specify the HLQ prefix. If it is not specified, the prefix is set to the high-level qualifier of the dataset from which the SSMC CLIST is executed. We recommend passing the USR parameter as well; the parameter will be saved in the user's SSMC profile. If you do not specify the USR parameter, SequeLink retrieves the last passed value from your SSMC profile. If neither parameter is passed, and no value can be retrieved from your profile, the default value HLQ is used.

> For example:

> `TSO EX 'SQLNK.V6R0M0.CLIST(SSMC)' 'HLQ(SQLNK.V6R0M0) USR(`COMPANY.DEV)`'`

> or

> `TSO EX 'SQLNK.V6R0M0.CLIST(SSMC)' 'USR(COMPANY.DEV)'`

> The HLQ used will be the HLQ from which the SSMC CLIST is fetched.

> NOTE: In the first example, the HLQ specified to locate the SSMC CLIST might be different from the HLQ argument passed. This is especially important when administering two different versions of SequeLink. In this case, we recommend that you always specify the HLQ argument explicitly.

> 4. When the Serverlist dataset (USR_prefix.SERVER) has not been allocated for the environment USR, you are prompted for the necessary information. Press ENTER to continue. The SequeLink Manager for z/OS main menu appears.

> 5. If you select NO, you exit the SSMC application. If you select YES, the following panel appears. Enter `VOL(`vvvvvv`)` where vvvvvv is the volume on which you want to allocate the serverlist dataset. This volume will be used to allocate server-specific datasets for SequeLink servers that are added to this environment. Press ENTER to continue.

> 6. When you start the SequeLink Manager for z/OS, copyright information appears. Press ENTER to continue. The SequeLink Manager for z/OS ServerList panel appears.
