Creating or modifying full-function or Fast Path database PCBs
Use the full-function or Fast Path database PCB statement section of the PSB summary page to create or modify a full-function or Fast Path database PCB statement.
Before you begin
Procedure
- From the full-function or Fast Path database PCB statement
section of the PSB summary page, you
can create a full-function or Fast Path database PCB statement, and
remove and modify existing statements.
- To create a PCB statement, click Add. A new row is added to the table and the statement properties you can modify are displayed. A sequential PCB number uniquely identifies the new row.
- To remove a PCB statement, click a row in the table to select it, then click Remove. To remove multiple statements, select multiple rows by clicking Shift+Click, then click Remove.
- To edit a PCB statement, click a row in the table to select it, then click Edit and modify the properties. You can edit only one statement at a time.
Property Required or optional Description PCB name Required if LIST=NO or if you want to use a Java™ metadata class 1-to-8 alphanumeric character PCB name or PCB label that must be unique within the PSB. The name cannot start with a numeric character. Alias (EXTERNALNAME)
Optional
A 1- to 128-character uppercase alphanumeric string that represents the alias of the PCB. Java application programs use the external name to refer to the PCB.
Database name Required 1-to-8 alphanumeric character name of the physical or logical database description (DBD) to be used as the primary source of database segments for this PCB. Processing options (PROCOPT) Required Processing options on sensitive segments declared in this PCB. You can specify up to four options. The default is A. Use sequential buffering (SB) Optional Specifies whether this PCB uses sequential buffering. The default is No. Longest concatenated key (KEYLEN) Required Length of the longest concatenated key for a hierarchic path of sensitive segments that the application program uses in the logical data structure. Positioning for the logical data structure (POS) Optional Single or multiple positioning provides a functional variation in the call. The default is Single. Secondary processing sequence index name (PROCSEQ) Optional Name of a secondary index that is used to process the database named in the DBDNAME parameter through a secondary processing sequence. This property is valid only if a secondary index exists for this database. Use MSDB commit view (VIEW=MSDB) Optional if the PSB refers to a DEDB database Specifies the main storage database commit view (Yes) or the DEDB commit view (No) for DEDBs. The default is No. Include named PCB in the PCB list (LIST) Optional Specifies whether to include this PCB in the PCB list that is passed to the application program at entry. The default is Yes. - Optional: You can open the database PCB editor to define which segments and fields in the database PCB an IMS™ application program is sensitive to. To open the editor, click Edit PCB Segment.
