    Since we don't know anything about your system, we have no way of knowing what services you might want to end or start. Often, none need to be ended -- perhaps only a few lingering connections might be ended, though some applications are good enough to care of that themselves. I have a couple systems that I can back up all user libraries without ending anything even though I have all of the usual servers running. Tom

    Dear Tom, Good day! First of all thanks for nice response. Actually i used services words instead of lingering connections thank you for correction. If we need to end lingering connections then please guide how to end and how to start again. And step by step procedure to take backup all libraries or specific library. Thanks, Regards, Tahir

    Some ODBC connection jobs (QZDASOINIT) may be holding locks on objects. The ODBC prestart jobs could be interpreted as a "service". To end those : ENDPJ PGM(QZDASOINIT) SBS(QUSRWRK).

    QZDASOINIT will start back up whenever an ODBC connection is opened. Are you looking to save a single library, a group of libraries, or the entire system? If the latter, are looking to save everything, system and non-system, or are you looking to just save the non-system items? There are a number of ways to approach this, and it depends on what you're trying to accomplish.

    If we need to end lingering connections then please guide how to end and how to start again. Usually connections are made from PCs or PC servers to your database through ODBC/JDBC or to shared directories in the IFS. The database server can hold locks on files after ODBC connections finish, often because the ODBC processes don't clean up after themselves. Those locks from "lingering connections" can interfere with some backups. You can take care of most of those by ending the servers (services) before the backups start. The servers that are most often in use are the "host" servers. These are ended with the ENDHOSTSVR command. An example is:
    ENDHOSTSVR SERVER(*ALL) ENDACTCNN(*DATABASE *FILE)
    The example ends all of the host servers. It also ends any connections to the *DATABASE (ODBC/JDBC) and *FILE (IFS shared directories) that were started before the servers were ended. After backups finish, you can restart the servers with:
    STRHOSTSVR SERVER(*ALL)
    You can choose to end only some of the host servers instead of *ALL, but there are few reasons to leave any of them active if *DATABASE and *FILE are ended. If you use Management Central, you should end it before ending the host servers and restart it after the host have been restarted:
    ENDTCPSVR SERVER(*MGTC)
    and
    STRTCPSVR SERVER(*MGTC)
    With the servers ended, there won't be any new connections starting until you get the servers started again. Tom
