preupgrade

Syntax

preupgrade [-v] [-h] [-N]
	[-p [skip_sybprocs]
	[-D database_name]
	[-I interfaces_file]
	[-P password]
	[-S server_name]
	[-U user_name]
	[-X option[,option]...]

Parameters

• -D database_name – limits checking to the named database and a subset of possible checks. Use this parameter to check newly loaded databases before bringing them online.
• -h – prints help text and then exits.
• -I interfaces_file – specifies an interfaces file for the server. The default is $SYBASE/interfaces.
• -N – specifies preupgrade is to run in noninteractive mode. Thus, if preupgrade determines that any database is too small, the utility exits immediately.
• -p [skip_sybprocs] – specifies whether you want to skip the parsing validity test on stored procedures.
  During the upgrade process, stored procedures are automatically re-created internally from the text source, requiring that they be parsed correctly. The valid options for preupgrade -p are:

  • -p – skips the parsing in all databases

  • -p skip_procs – skips parsing in sybsystemprocs while parsing the other databases

  • Not using -p – parses text everywhere. This is the default.

• -P password – specifies the password for connecting to the server. SAP recommends that you do not use this option on the command line as the password is then visible to other users when they view displays of system information. Rather, wait until the SAP ASE server prompts for a password, and enter the information then.
• -S server_name – specifies the name of the server to which you want to connect. This server must be listed in the interfaces file specified by the -I parameter. The default is $DSQUERY.
• -U user_name – specifies the user name to use when connecting to the server. The default is “sa.” user_name must have “sa_role” privileges on the server being checked.
  Note: If you use the -D option, which limits checking to a named database, and that database is offline, enter “sa” or accept the default as the user name.
• -v – prints version information and exits.
• -X option[, option...] – specifies a list of checks to be made. The default is all checks, except when using the -D option, which uses only a subset of available checks. If you specify the -X option more than once on the command line, preupgrade performs only those checks in the last entered -X parameter.
  When using the -X parameter with an options list, either:

  • List options without a space between the comma and the next option, or

  • Surround the options list with quotes.

  Valid check options are:

  Check Option	Option Used With the -D Parameter	Description
  all		Performs all permitted checks. When used with the -D option, only checks subset of options. Otherwise, all options are checked.
  cache		Checks the definition of default cache size. If the definition is DEFAULT, enter its current value in the configuration file as its actual value. This ensures that its size does not change because the new server’s default value is different from the current server’s default value.
  config		Checks the server’s configuration parameters to see if they are consistent with new requirements, and reports discrepancies. Discrepancies can cause errors or warnings for certain parameters: Errors – occur when the current value of a parameter is outside the new server’s range, or when its value is too low for upgrade. Warnings – occur when the current value of a parameter is between the maximum and minimum values, but less than the default value
  data_mods		Performs updates to system tables, including clearing certain system table columns that are non-zero. Applies primarily to older SAP ASE servers, and will make no changes to newer systems.
  datatype	X	Checks the systypes table to make sure that if existing datatypes use a system-defined name, type, or user type, they match what the new server expects. Reports discrepancies and suggests remedies.
  db_size		Checks that certain system databases meet the minimum size requirements for installation.
  free_space	X	Checks for free space in the named database or in all databases. Makes sure that there is sufficient free data and log space to perform the necessary upgrade steps.
  object_id	X	Checks that object IDs of user-defined objects are not reserved for system objects. SAP ASE 15.0 and later reserves objects IDs 1 – 255. SAP ASE 12.5.x and earlier reserves object IDs 1 – 99. Does not issue an error. If you receive a warning that a user object ID is reserved, contact Technical Support for directions for changing the user object ID after upgrade.
  required_dbs		Checks that required system databases exist. Some versions of SAP ASE may require specialized databases such as sybsystemdb.
  sproc_text	X	Checks for the existence of stored procedure text in the named database or in all databases. After upgrade, the SAP ASE server must recompile stored procedures from their source text. This check makes sure that all of the source text is both available and valid.
  srvclass		Checks for servers classed as “generic” in master.dbo.sysservers. This class is deprecated by SAP ASE 12.0 and later.
  statistics		Checks for duplicate rows in sysstatistics. Duplicate rows may occur when upgrading from SAP ASE 12.0 to SAP ASE 15.0 and later due to schema changes in the sysstatistics table.

  Versions of SAP ASE may occasionally change valid options for the -X parameter; use the -h parameter to view the current set of valid options.

Examples

• Check options (-X) – Specifies checks for the default cache size, minimum database size, and duplicate rows in sysstatistics for the installation:

  preupgrade –X cache,db_size,statistics

• Check database (-D) – Checks a newly loaded, offline database for datatypes, free space, object IDs, and stored procedure text:

  preupgrade –Dmy_db –Usa

• Noninteractive mode (-N) – Shows how the sqlupgrade utility uses preupgrade. When used in this way, preupgrade checks all databases, runs noninteractively, and exits with a failing status if any database is too small:

  preupgrade –N

Permissions

The user login specified by the -U parameter must have system administrator privileges to run preupgrade on the server specified by the -S parameter.

When using the -D parameter to check an offline database, preupgrade must log in as user “sa.” The “sa_role” privilege is insufficient.
