Installing Oracle GoldenGate for HP NonStop (Guardian)

12c (


July 2017

Once you decide how you want your data management environment to operate, you are ready to design its infrastructure and install Oracle GoldenGate for HP NonStop. This document describes how to install Oracle GoldenGate data replication software for the HP NonStop platform using the Guardian operating system.

This chapter includes the following sections:

Overview to Installing Oracle GoldenGate for HP NonStop

When you install Oracle GoldenGate for HP NonStop, you install Oracle GoldenGate components such as:

  • Audserv


  • Manager

  • Logger

  • Extract

  • Collector

  • Replicat

  • Coordinator

  • Reader

  • Syncfile



  • Supporting files, such as help

The install program auto-detects your Guardian operating system version and installs the native version of Oracle GoldenGate code where applicable. You can also tell Oracle GoldenGate to install TNS code during the installation routine.


TNS Audserv is no longer supported as of release 12.1.2 and later.


HP NonStop Server installations use the UNPAK utility. Verify that you have a copy of this utility before proceeding.


Use a maximum of six characters to name any volume used for files or tables to be processed with Oracle GoldenGate for HP NonStop. $CADATA is supported, but $CADATA1 is not.

Installing Oracle GoldenGate for HP NonStop

Follow these steps to use the downloaded file to install Oracle GoldenGate for HP NonStop.

  1. Save the downloaded file to a directory on your workstation and unzip it to a temporary folder.

  2. Upload the GGSUNPAK and GGSOS_versionPK files in binary mode to the volume and subvolume on your HP NonStop Server where you want to install and run Oracle GoldenGate. We recommend that you preface the subvolume name with GGS and include the release of Oracle GoldenGate. For example, if you are installing Oracle GoldenGate release 12.1.2, then we recommend you install on $PROD.GGS1212.


    If you are using Oracle GoldenGate against a TMF-enabled (or audited) database, then Oracle GoldenGate must be installed on a volume that is TMF-protected because the internal Oracle GoldenGate file must be audited.

  3. Alter GGSUNPAK to be an Edit file.

  4. Run GGSUNPAK and confirm the installation location. If the correct location is not displayed, you are prompted for it, as shown here.

    TACL 2> run ggsunpak
    Installing Oracle GoldenGate at $DATA4.CPSTEMP 
    Is this correct?(Y/N) N
    Enter the volume and subvolume to install Oracle GoldenGate: $VOL.GGS1111
    Installing Oracle GoldenGate at $VOL.GGS1111

    *   please pay attention to the prompting        *
  5. (The prompts in this step appear only on a G06.16 operating system.) For G06, you are asked if you need TNS versions of Extract and Replicat. Oracle GoldenGate recommends using the Native versions of these components, but if you have TNS mode user exits, enter Y at the prompts to install the TNS versions.

    Since you are installing G06.16, we are installing Native mode objects.
    Do you use TNS mode User Exits in Extract (Y/N)? N
    Do you use TNS mode User Exits in Replicat (Y/N)? N
    $DATA11.GGS1111.TEMP1 purged.


    For the purposes of this documentation, it is assumed that Native mode objects will be installed.

  6. You are asked whether to build Oracle GoldenGate intercept libraries. Oracle GoldenGate recommends building a GGSLIB object, but it can be omitted if you do not need to capture non-audited Enscribe files or FUP-related activities. (You can build a GGSLIB object later.)

    *   If you need the TNS mode GGS Intercept      *
    *   Library GGSLIB then answer Yes,             *
    *   Otherwise you can skip this step.           *
    Build of new GGSLIB recommended. Build now (y/n)? Y
  7. The BUILDMAC utility runs and searches for run-time libraries to bind with GGSLIB, and you may be prompted that one or more libraries is missing. Enter Y to continue.

    *** Running BUILDMAC to build GGSLIB ***
    Looking for runtime libraries to BIND with GGSLIB
    One or more libraries was missing. Continue anyway? (Y/N) Y
  8. You are asked if you want to include a user library. Respond either Y or N.

    Do you want to include your own User Library (y/n)? N
  9. You are asked if you want to change the location of the AUDCFG.

    Do you want to change the location for the AUDCFG segment (Y/N): N

    If you respond with yes, it prompts you for the new default location ($vol.subvol) of the AUDCFG segment.

    Assuming you opted to build the intercept libraries, you will see the BIND steps being performed. You may see the following Binder messages that can be safely ignored. They are:

    WARNING 60: Parameter mode mismatch on PXS_FILE_WRITE_parameter2. Parameter mismatch between two external procedure declarations. The parameters are declared as STRING and OTHER.
    WARNING 61: Parameter type mismatch on PXFS_FILE_WRITE_parameter2. Parameter mismatch between two external procedure declarations. The parameters are declared as INT32 and OTHER.
    WARNING 61 Parameter type mismatch on PXFS_FILE_WRITE_parameter3.

    Other warnings may also be displayed and can be ignored.

  10. You are asked if you want to build the native mode Oracle GoldenGate intercept libraries GGSSRL/GGSDLL. To install native code, enter Y and continue to the next step; otherwise, enter N to use TNS code and then skip to step 17.

    *   If you need the Native mode GGS Intercept   *
    *   Library GGSSRL/GGSLIBR then answer Yes,     *
    *   Otherwise you can skip this step.           *

  11. The NLDLIB macro runs, and you are asked if you want to include a user library. Reply either Y or N.

    *** Running NLDLIB to build GGSLIBR & GGSSRL ***
    NLDLIB builds the native relinkable libraries GGSLIBR and GGSSRL
    A Native mode GGSLIB needs the re-linkable versions of some
    Tandem SRLs. ZCREREL and ZCOBREL. If Native cobol support is not
    required then ZCOBREL may be omitted.

    Enter X at any prompt to EXIT
    Do you want to include your own User Library (Y/N) : N
  12. You are asked if you want to change the location of the AUDCFG.

    Do you want to change the location for the AUDCFG segment(Y/N) : N

    If you respond with yes, it prompts you for the new default location ($vol.subvol) of the AUDCFG segment.

  13. You are asked if you want to include ZCREREL. It is recommended to enter Y to include it unless you know your applications do not use these libraries.

    Do you want to include ZCREREL (Y/N) : Y

    NLDLIB searches for ZCREREL locations and displays them.

    Looking for ZCREREL ..
    $DATA09.R1269G09.ZCREREL $DATA09.R8431G09.ZCREREL
  14. You are asked to enter the location of the ZCREREL to use.

    Enter location of ZCREREL : $SYSTEM.SYS03.ZCREREL
  15. You are asked if you want to include ZCOBREL. It is recommended to enter 3 to include it unless you know your applications do not use these libraries.

    Do you want to include ZCOBREL (Y/N) : Y

    NLDLIB searches for ZCOBREL locations and displays them.

    Looking for ZCOBREL ..
    $DATA09.R8107G09.ZCOBREL $DATA09.R8108D46.ZCOBREL
  16. You are asked to enter the location of the ZCOBREL to use. If you plan to use COBOL, enter a location; otherwise, you can press Enter to bypass this prompt.

    Enter location of ZCOBREL : $SYSTEM.SYS03.ZCOBREL


    If you omit a ZCOBREL location, you are prompted to confirm your choice:

    Omit ZCOBREL (y/n):Y

    NLDLIB builds the GGSLIBR and GGSSRL libraries, displaying a series of informational messages and the names of the files that were created.


    On systems running Guardian G06.23 or earlier, the GGSUNPAK utility installs and accelerates Audserv and Logdump. If you are running G06.24 or later, you will not see any acceleration messages.

  17. You are asked if Oracle GoldenGate should use an existing SQL catalog or create a new catalog. Either enter X to specify no catalog or enter the name of a catalog to use. If you enter a catalog name and it does not exist, you are asked whether to create it.

    SQL Catalog for Compilation (X for no catalog)? GGSCAT
    Catalog $TRNG04.CPSCAT does not exist. Create it (Y/N)? Y

    The SQL compilation completes, and then libraries and programs are linked. This happens automatically and does not require action from you.

  18. You are asked if you want to migrate information from another Oracle GoldenGate environment. If you are installing Oracle GoldenGate for the first time, enter N. A migration requires shutting down existing Oracle GoldenGate processes and, if Logger is being used, the user application. (The following assumes a new installation.)

    Would you like to Migrate information
    from another GGS Environment (Y/N)? N
  19. You are advised to license your programs as shown in the following prompt, and then the installation utility finishes.

    Make sure to secure files appropriately. If EXTRACT is to be executed
    outside of the SUPER group, you must PROGID and LICENSE the AUDSERV
    program for SUPER.SUPER authority. PRIVLIB must also be licensed
    if executing Replicat outside SUPER group.
    Audserv/LOGDUMP licensing only applies to TMF installations.
    TMFARUL2 must be licensed
    The Native Audserv must be licensed (A TMFARUL2 restriction)
    The Native Logdump must be licensed if you are going to use it
    to read TMF trails (A TMFARUL2 restriction)
    -GIVE Audserv, SUPER.SUPER
    -SECURE Audserv, "NUNU", PROGID
    -LICENSE Audserv
    Installation Complete.

    Licensing must be run by SUPER.SUPER because the following privileged access is required:

    • Audserv and TMFARUL2 access the TMF trails through audit read routines.

    • PRIVLIB contains privileged Replicat code that runs certain privileged FUP DUP or FUP LOAD operations.

    • Logdump provides a version that can read the audit read routines. If you do not want Logdump to be able to read the audit trails, do not license it.


      If the version of your SQL catalog does not allow FUP to alter the program, you can PROGID and license the programs by using the following commands to license the components shown.

     >> EXIT
     - EXIT
  20. Once your product is installed, log on as the owner of your Oracle GoldenGate environment.

  21. (Optional) You can purge the *PK files, if desired.

Preparing your Production Environment

This section outlines considerations that impact the overall architecture of your particular Oracle GoldenGate environment. These considerations include:

  • Sizing

  • CPU requirements

  • Disk space requirements

  • Data communications requirements


Before you begin running Oracle GoldenGate in your production environment, you should consider several factors regarding the size of your replication environment, including the following statistics.

  • Counts of inserts, updates and deletes generated on a per-file basis. A common reference point is the application's transaction rate, from which these numbers can often be estimated.

  • The byte generation rate caused by inserts, updates and deletes. Use this statistic to estimate disk space requirements and communications bandwidth. Byte generation totals during peak periods and over an extended time frame are also important.

  • For update-intensive applications, the number of bytes in a record that change during an update. This is probably the most difficult statistic to extract (especially for Enscribe files) but can have a dramatic impact on bandwidth requirements. The number of bytes that change in a record during an update determines the compression rate for the record.

  • The cache hit rate and file busy percentages of the most heavily updated files. This has a direct bearing on the throughput possible by individual Replicat processes on the target system.

  • Which programs are causing the heaviest amount of update activity. It is often possible to avoid replicating certain types of activity (such as FUP LOAD) by excluding those programs from replication. Measuring individual programs is a concern primarily for non-TMF data processing.

Reducing Overall Requirements

In some cases, due to bandwidth or application constraints, it can be desirable to eliminate certain files, programs or processes from Oracle GoldenGate.

To get a view of overall replication activity excluding certain files or programs, use the EXCLUDEPROGRAM parameters.

CPU Requirements

CPU requirements for Oracle GoldenGate components vary primarily according to transactions rates, record sizes, and the I/O mix (numbers of updates versus inserts and deletes).


The following section details system performance statistics in a variety of situations. However, your operating environment, including operating system versions, hardware, and network topology will affect the performance you experience. The following figures should be taken only as guidelines, useful for reference when you are planning your Oracle GoldenGate implementation.

As a percentage of overall application processing, Oracle GoldenGate as a general rule requires more CPU resources when:

  • I/O is a larger percentage of overall application processing.

  • Files are buffered.

  • TMF auditing is off.

  • Cache hits are high.

  • When TMF is on, audit compression is used.

  • All files are replicated.

More power is required because the application can produce relatively more I/O under these conditions.

TMF Data Extraction and Transfer

Oracle GoldenGate extracts data in TMF applications by reading TMF audit trails (using the Audserv program). Audserv passes the data in large blocks to Extract, which formats and moves the data to the target system.

Oracle GoldenGate has observed TMF extraction takes between 1% and 10% of overall system processing. Typically this figure is 2-3%, but can skew higher when:

  • The database is SQL.

  • As a percentage, there are a high number of updates in the application.

  • The SQL update statements set a large number of columns.

Non-TMF Data Extraction and Transfer

Non-TMF data extraction takes more processing power than TMF because blocks of data are written to log trails on disk, then transferred to the target system by Extract in a separate step.

It has been observed that non-TMF extraction activities take between 2% and 14% of overall application processing. This means that, if the application is running with an average of 50% busy for the CPUs, after replication is implemented the CPUs will be between 51% and 57% busy. This represents a significant variance and can be traced to the environmental factors listed above.

Intermediate Oracle GoldenGate Trails

You can improve performance by writing data to intermediate trails. An intermediate trail is a trail written by Extract, extracted again, and transferred to Replicat. I/O to intermediate Oracle GoldenGate trails is serial, buffered and blocked at 28K bytes when the system is busy. This means that I/O rates upwards of three gigabytes per hour are possible to trails on the target (Higher rates are possible when you are running multiple instances of Extract, IP channels and controllers.) The impact of writing one gigabyte of data per hour using Extract has been measured to consume 5.5% of a single CPU on an S7000 system. (See the Note at the beginning of this chapter regarding system variance and its impact on performance.)

Any impact resulting from intermediate trails is absorbed by the target system. The volume of data written to the target is likely to be far less than the corresponding audit generated on the source system for TMF applications.

To minimize contention with other disk activity, isolate trails on separate disk drives when possible.

Replicat Performance

Replicat performance on the target system is related closely to the I/O performance on the source system, as I/O is essentially the same on both. This means you can estimate the impact of I/O on the target system by determining the File Busy percentage of application files and tables on the source system.

Disk Space Requirements

Disk space requirements can vary depending on whether you are processing data from TMF-enabled applications or from non-TMF-enabled applications.

TMF Data Requirements

TMF replication requires temporary storage for data read from audit trails. In most scenarios, extracted data is written directly to the target system. TMF audit trails generally act as safety storage if the target system or communication channel is unavailable or performing slowly.

In most cases, you must reserve enough space for TMF audit trails to tolerate an outage of one or more days. To determine your space requirements, check the rate at which audit is generated for a week or month and average the amount of space filled per day. Oracle GoldenGate can process tape dumps, so you can have a backlog as old as the oldest tape dump. However, restoring a tape dump can be cumbersome and usually requires manual intervention, so disk is preferred whenever possible.

Another way to reduce source system disk requirements is to store data in a local trail, then move it across the network through a separate Extract process. In many cases, the amount of data written to a trail by Extract is far less than the corresponding amount of data in the audit trails, especially when a subset of data is being replicated. Filtering unnecessary data in this manner reduces the total disk requirement.

Non-TMF Requirements

Non-TMF database changes are stored in a log trail, which must be a local trail. Logged data is subsequently moved to the target system and replicated.

During typical activity, records in the log trail are replicated almost as soon as they become available, making the amount of disk required quite low. However, you must consider more extreme conditions when sizing disk space. For example, replication activity can fall behind due to:

  • Target system maintenance (which might require suspension of Replicat processing)

  • Slow data replication on the target due to other activity on the system

  • Slow or downed communications links between the source and target

When any of these conditions arise, you must store backlog locally. Many organizations use the general rule of accommodating one full day's worth of database updates. Allocate the number of bytes generated during this period for log trails on the source system.

In addition, you can move data to trails on the target system to minimize data loss caused by potential delays in Replicat processing. Size these trails for potential delays in replication.

When sizing for longer outages (for example, more than one day), you can use tape backups to reduce the amount of disk required.

Data Communications Requirements

Each record Oracle GoldenGate sends to the target system includes a header portion and a data portion. To compute total byte generation and transfer requirements in a given period, sum the byte counts of the headers and data for each record inserted, updated or deleted during the period.

The overall amount of activity can be calculated using the following statement. (Headers vary in size, however, the average is approximately 50 bytes. For this reason, the following example uses an 80-byte header.)

(number of inserts * (size of average insert + 80)) +
(number of deletes * (size of average record + 80)) +
(number of updates * (size of averaged compressed update + 80))

For Enscribe files, the size of insert and delete records can vary and may not be the same as the record size for the file (which represents the maximum size of each record). For inserts and deletes, all bytes in the record are transferred, along with a header.

For SQL tables, all bytes are transferred for insert and delete records as well.

With Oracle GoldenGate, the following data is not transferred to the target system:

  • Images of updates before the update occurs (Only after-images are sent for hot site backup.)

  • Alternate key data

  • SQL indexes

  • Data generated by FUP RELOAD

  • Assorted other TMF records

When sizing data communications bandwidth, peak byte generation is important. Bandwidth that can accommodate peak volumes helps guarantee low latency between the source and target databases at all times.

When moving data, Extract accumulates and sends records in 28K blocks across the network whenever database activity is high. Therefore the amount of data moved through Extract over a communication channel can be approximately 75-80% of channel capacity. For example, on a 10-megabit Ethernet network with approximately 4-megabits per second of true throughput, Extract can move approximately 3.5M bits per second (430KB/sec).


All network performance statistics are suggestions. Your own network configuration, bandwidth demand, and operating environment will determine the kind of performance you can expect. You can boost actual throughput considerably by using router-based compression between the source and target systems (a 4 to 1 ratio is fairly typical). This is in addition to update compression used by Oracle GoldenGate modules. For more information, contact your network vendor or NonStop representative.

When sizing communications requirements, note that Oracle GoldenGate can send data over multiple TCP/IP channels simultaneously. You can achieve total bandwidth requirements over multiple lines or networks as an alternative to a single path.

Preparing the Source and Target

Once you have addressed Oracle GoldenGate planning considerations, you are ready to meet its prerequisites. These include:

  • Downloading source data definitions

  • Synchronizing source and target

Downloading Source Data Definitions

You can optionally download source data definitions from the source database into a definitions file on the target system. In most cases, you will want to download source data definitions to the target.

When the target resides on another NonStop system, run the DEFGEN utility to download data definitions. When the target resides on Windows/UNIX systems, run the DDLGEN utility to download data definitions.

Synchronizing Source and Target

Before running online synchronization for the first time, run an initial-load process to synchronize the source and target. This applies a copy of the source to the target. If Extract or Replicat stops running for any reason, you may need to re-synchronize the source and target and restart the Extract and Replicat groups to reset the checkpoints. For further assistance with your initial load, see the Oracle GoldenGate for Mainframe Administering for HP NonStop (Guardian) guide.
