sybsystemprocs

sysprocsdev is the default system name for this device. However, it is frequently referred to as the sybsystemprocs device, as in the Adaptive Server attribute screen, since it stores the sybsystemprocs database.

Verify that the sybsystemprocs database is large enough. For an upgrade, the recommended minimum size for sybsystemprocs is the larger of 105MB, or enough free space to accommodate the existing sybsystemprocs database, and the largest catalog that is to be upgraded, plus an additional 10 percent of the largest catalog’s size. The additional 10 percent is for logging upgrade changes.

You may need more space if you are adding user-defined stored procedures. 105MBs accommodate additional internal data structures, but does not account for the possibility of a large number of user-defined system procedures.

If your sybsystemprocs database does not meet these requirement and you have enough room on the device to expand the database to the required size, use the alter database command to increase the database size.

Use sp_helpdb to determine the size of the sybsystemprocs database:

1> sp_helpdb sybsystemprocs
2> go

Use sp_helpdevice to determine the size of the sysprocsdev device:

1> sp_helpdevice sysprocdev
2> go

If the db_size setting is less than the required minimum, you must increase the size of sysprocdev.

Increasing the size of the sybsystemprocs database

If your current sybsystemprocs database does not have the minimum space required, you have two options for creating a new database with sufficient space for the upgrade:

You can drop the old database and the device and create a new sysprocsdev device, or
You can leave the database and old device alone and add a new device large enough to hold the additional megabytes, and alter the sybsystemprocs onto the new device. Sybase recommends expanding the current device.

To enlarge the sybsystemprocs database:

If you do not have a current backup, create one.
In isql, use alter database to increase the size of the sybsystemprocs database. For example:
```
1> use master
2> go
1> alter database sybsystemprocs on sysprocsdev=40
2> go
```
In this example, “sysprocsdev” is the logical name of the existing system procedures device and “40” is the number of megabytes of space to add.

If the system procedures device is too small, you may receive a message similar to the following when you try to increase the size of the sybsystemprocs database:
```
Could not find enough space on disks to extend database sybsystemprocs
```
If there is space available on another device, you can expand sybsystemprocs to a second device, or initialize another device that is large enough. For instructions on creating a larger sybsystemprocs device, see “Increasing device and database capacity for system procedures”.
To verify that Adaptive Server has allocated more space to sybsystemprocs, issue:
```
1> sp_helpdb sybsystemprocs
2> go
```

When the system procedures database is large enough to accommodate the increased size of the sybsystemprocs database, continue with the other pre-upgrade tasks.

Increasing device and database capacity for system procedures

If you cannot fit the enlarged sybsystemprocs database on the system procedures device, increase the size of the device and create a new database.

This procedure involves dropping the database. For more information on drop database, see the Reference Manual.

WARNING! This procedure removes all stored procedures you have created at your site. Before you begin, save your local stored procedures using the defncopy utility. See the Utility Guide for more information on Adaptive Server utilities.

To create a larger system procedures device (sysprocsdev):

Determine which device or devices you need to remove.

WARNING! You must not remove any device that is in use by database other than sybsystemprocs, or you will destroy that database.
```
select d.name, d.phyname 
from sysdevices d, sysusages u 
where u.vstart between d.low and d.high 
and u.dbid = db_id("sybsystemprocs") 
and d.status & 2 = 2 
and not exists (select vstart 
    from sysusages u2
    where u2.dbid != u.dbid 
    and u2.vstart between d.low and d.high)
```
where d.name is the list of devices to remove from sysdevices and d.phyname is the list of files to remove from your computer.

The “not exists” clause in this query excludes any devices that are used both by sybsystemprocs and other databases.

Note the names of the devices; you will need them in the coming steps.

Drop sybsystemprocs:

use master
go
drop database sybsystemprocs
go

Find another existing device that meets the requirements for additional free space, or use a disk init command similar to the following to create an additional device for sybsystemprocs:
```
1> use master
2> go
```
```
1> disk init
2> name = "sysprocsdev",
3> physname = "%SYBASE%\data\sysproc.dat",
4> vdevno = 9,
5> size = 51200
6> go
```
where %SYBASE%\data is the path to your system procedures device.

The number for vdevno must be available. For information about determining whether vdevno is available, see the System Administration Guide.

The size you provide should be the number of megabytes of space needed for the device multiplied by 512. disk init requires the size to be specified in 2K pages. In this example, the size is 105MB (105 x 512 = 53760). For more information on disk init, see the Reference Manual.
Create a sybsystemprocs database of the appropriate size on that device, for example:
```
1> create database sybsystemprocs on sysprocsdev = 105
```
```
2> go
```

Run the instmstr command in the old release directory. For version 12.0:

isql -Usa -Ppassword -i%SYBASE%\%SYBASE_ASE%
\scripts\instmstr -oinstmster.out

For version prior to 12.0:

isql -Usa -Ppassword -i%SYBASE%\scripts\instmstr 
-oinstmster.out

You must reinstall the system stored procedures for use later in this procedure.
