Changes to the JCICS API: removed classes and methods

Table 5. Previously deprecated methods and classes which have been removed. Any applications that use these methods and classes must be changed before moving to CICS TS 6.1.
Class/Interface Methods 6.1
Program

link(IByteBuffer)

link(IByteBuffer, IByteBuffer)

REMOVED: The previously deprecated methods link(com.ibm.record.IByteBuffer) and link(com.ibm.record.IByteBuffer,com.ibm.record.IByteBuffer) have been removed from the class com.ibm.cics.server.Program.

Any OSGi dependencies or code dependencies on the com.ibm.record package should be removed from customer applications and builds. Correspondingly, the JAR file ${USS_HOME}/lib/com.ibm.record.jar has been removed from the CICS installation.

To ease migration of these changes, the package com.ibm.record (now empty) is declared as exported by the com.ibm.cics.server bundle. This avoids the need for repackaging or recompiling applications that express an unnecessary dependency on that package. If, however, your application genuinely uses these methods at runtime, you must rewrite that application - the API is no longer supported by CICS.
CicsSecurityManager

checkMultiCast(InetAddress, byte)

checkAwtEventQueueAccess()

checkMemberAccess(Class<?> theClass, int which)

checkSystemClipboardAccess()

checkTopLevelWindow(Object window)

 REMOVED: These methods override methods in java.lang.SecurityManager, which are deprecated by Java. They have now been removed from the CicsSecurityManager.java class.

The checkTopLevelWindow(Object window) method always returned true, and the other methods were no-operation methods.

If your application calls these methods, you should instead invoke checkPermission(java.security.Permission) as recommended by the Javadoc for these methods.
TerminalPrincipalFacilityExtended   REMOVED: This entire class is removed.

This class was provided in CICS TS 1.3 to support additional functionality for the TerminalPrincipalFacility class, when using the Enterprise Toolkit for OS/390® (Java program objects). In CICS TS 2.1 and later, for interpreted Java (JVM programs), the additional functionality is now available directly in the TerminalPrincipalFacility class.

Applications that call this class should be changed to call the same method from the TerminalPrincipalFacility class.
TerminalPrincipalFacility

waitTerminal()

 REMOVED: The previously deprecated method waitTerminal() is removed. All methods in the class are synchronous so there is never a need to wait for the terminal.

The deprecated method was a no operation method. Calls to this method should be removed from your application as it is no longer supported by CICS.
HttpHeader

getHeader()

 REMOVED: The previously deprecated method getHeader() is removed. This deprecated method returns the name of the HTTP header by calling method getName().

If your application uses this method, you must rewrite that application to call getName() directly because it is no longer supported in CICS.
Task

disableTaskTrace()

enableTaskTrace()

 REMOVED: The previously-deprecated methods disableTaskTrace() and enableTaskTrace() are removed. These deprecated methods currently throw an exception with a message saying Method is not supported in this release of CICS TS.

Calls to both methods should be removed from your application because they are no longer supported by CICS.
Container

put(String stringData)

 REMOVED: The previously-deprecated method put(String stringData) is removed. This deprecated method risked exhibiting unexpected behavior due to the way the underlying container was created.

Replace calls to this method with putString(String stringData).
ILongHolder   REMOVED: This entire class is removed.
AbendError   REMOVED: This entire class is removed.
UnknownCicsError   REMOVED: This entire class is removed.

Changes to the JCICS holder classes

Table 6. A number of classes which were used to hold data for objects (such as the CWA, TSQ items, file records, the commarea, and more) previously exposed public data fields. These fields were deprecated at CICS TS 5.1 and must now be accessed using an appropriate getter or setter method. Direct access to these fields has now been removed.
Class Removed field(s) Getter(s) Setter(s)
CWAHolder

public byte[] value;

public byte[] getValue()

public String getStringValue()

public void setValue(byte[] bytes)

Changes to the JCICS API - new, changed, and deprecated functions

Table 7. New, changed, and deprecated JCICS API functions in CICS TS 6.1
Function 6.1
com.ibm.cics.server.jar Changed:

Reduced footprint from 873K to 448K. If you are writing an application using RMI over IIOP, you need to include com.ibm.cics.delegate.jar (83K) and com.ibm.cics.common.log.jar (8K) to allow error information to flow back to the client.
CICS Exceptions Changed:

Exceptions include a public constructor, enabling applications to mimic any errors thrown by the JCICS API for unit testing.
Classes 6.1
Container Changed:

get() and getNoConvert(...) calls now require LengthErrorException to be handled at compile time.
Resource classes:
  • ESDS
  • KSDS
  • NameResource
  • Service
  • WebService
  • File
  • RRDS
  • KeyedFile
  • Program
  • TSQ
  • TDQ
 New:

These resources have a new name-bearing constructor allowing the resource to be created and named in one statement. For example:

new ESDS(name);

new Program(name);
Data holder classes:
  • CWAHolder
  • DataHolder
  • ItemHolder
  • KeyHolder
  • RecordHolder
  • RetrievedData
  • RetrievedDataHolder
  • TCTUAHolder
  • TWAHolder
  • CommAreaHolder
 New:

All holder-types have setters and getters to allow full manipulation of the data held within each holder. These setters and getters facilitate unit testing of application code. For more information, see Changes to the JCICS API - changes to the JCICS holder classes.
Task Deprecated:

Direct access to PrintWriter data members: fixedOutForJVMLifetime, fixedErrForJVMLifetime, err, out. Setter and getter methods for these deprecated data members are available to replace direct data member access.

New:

getStartCode() returns a stronger-typed StartCode enum value.

Deprecated:

int getSTARTCODE() - use getStartCode() instead.

Deprecated:

Method getQNAME() always returns null.
StartCode New:

Provides more explicit detail returned from the Task.getStartCode() method.
Version New:

Support of the comparable<Version> interface

New:

Constructor Version(String versionString)
API New:

Application code can check the version of com.ibm.cics.server.jar it is running against, with Version getCicsServerApiVersion()
ContainerIterator Deprecated:

Object getOwner()

New:

Channel getChannel()
Channel Changed:

It is possible to turn off explicit checking for the existence of underlying CICS container resources performed as default by channel.getContainer(…) calls by setting a new system property. Turning off explicit checking can reduce CPU usage.

New:

System property -Dcom.ibm.cics.server.container.existence.checking.default=false controls existence checking at a JVM level.

New:

channel.setContainerExistenceCheckingEnabled(boolean); controls existence checking at a channel level.

New:

channel.getContainer(String containerName,boolean existenceChecking); explicitly controls if existence checking is performed or not, instead of allowing defaults that are set in the channel or system property to have any effect.

New:

container.exists(); explicitly checks for the existence of the underlying CICS container resource.

New:

channel.isContainerExistenceCheckingEnabled(); checks if implicit checking for the existence of the underlying CICS container resource is enabled or disabled on future calls to channel.getContainer

New:

channel.getContainerNames(); returns a list of all the names of existing CICS containers associated with a channel.

Deprecated:

ContainerIterator, Channel.getContainerIterator, Task.getContainerIterator
IsCICS New:

getApiStatus (boolean lateBind); set lateBind to true if late binding to a CICS transaction is to be performed for current task and status is currently CICS_REGION_BUT_API_DISALLOWED.

Changes to SIT parameters

Table 11. Changes to system initialization parameters in CICS TS 6.1
SIT 6.1
CPSMCONN CHANGED: New option SMSSJ. CPSMCONN=SMSSJ initializes a single CICS region that is not part of a CICSplex as a CICS System Management Single Server (SMSS) and automatically creates a Liberty JVM server named EYUCMCIJ as the CMCI JVM server of the region.
DTRPGM CHANGED: When DTRPGM=NONE is specified, no routing program is invoked. If you are using a routing program with the name of NONE, you must rename the program and change the DTRPGM setting accordingly.
ENCRYPTION REMOVED: With the changes to enable support of TLS 1.3, the need for the ENCRYPTION parameter is removed.
EPCDSASZE NEW: Specifies the size of the EPCDSA dynamic storage area.
EPUDSASZE NEW: Specifies the size of the EPUDSA dynamic storage area.
KEYRING Service CHANGED with APAR:
  • APAR PH49261: The parameter accepts more formats of key ring names, which allows you to specify key rings that are not owned by the region user ID.
MINTLSLEVEL CHANGED: Option TLS13 is added. Options TLS10 and TLS10ONLY are removed. Option TLS11 is stabilized.
MAXTLSLEVEL NEW: MAXTLSLEVEL defines the maximum level of TLS currently in operation. Review the Enabling TLS 1.3 in CICS documentation before enabling TLS 1.3 on your system.

Changes to CICS storage

Table 12. Changes to CICS storage in CICS TS 6.1
Storage area 6.1
ETDSA REMOVED: Any storage that was allocated from this DSA is now allocated from the ECDSA.
PCDSA, PUDSA, EPCDSA, and EPUDSA NEW: To enable the allocation of storage that is not protected from instruction execution. These DSAs have new subpools and some subpools that have moved from the CSDA, SDSA and their equivalent extended DSAs. See CICS dynamic storage areas (DSAs).
Subpools LDPGM, LDEPGM, LDRES, LDERES, LDNRS, LDENRS, LDNUC, and LDENUC CHANGED: These subpools are now allocated in PCSDA, PUDSA, and their equivalent extended DSAs.
CDSA, SDSA, ECDSA, ESDSA locations CHANGED: Loader Domain functions ACQUIRE_PROGRAM, RELEASE_PROGRAM, INQUIRE_PROGRAM, GET_NEXT_PROGRAM, GET_NEXT_INSTANCE, and IDENTIFY_PROGRAM return the location of the program to the caller. These locations will change, the CDSA will become the PCDSA, the ECDSA will become the EPCDSA, the SDSA will become the PUDSA and the ESDSA will become the EPUDSA. Although the names of the DSA equated have changed, the equate values have not changed.

Changes to feature toggles

Table 13. Changes to feature toggles in CICS TS 6.1
Feature toggle 6.1
com.ibm.cics.container.hash={true|false} REMOVED: Hashing always used.
com.ibm.cics.cpsm.bas.largecicsplex={true|false} CHANGED: The default is changed from true to false.
com.ibm.cics.cpsm.bas.syslinkonly={true|false} Service NEW (APAR PH64941): Allows you to specify that only SYSLINK resources will be installed, and that RESDESC resources should not be installed during BAS automatic resource installation.
com.ibm.cics.cpsm.wlm.surgeresist={true|false} NEW: When applied to CICSPlex® SM WLM routing regions, this feature toggle takes effect for the QUEUE and GOAL WLM algorithms when using CICSPlex SM sysplex optimized workload routing. It has no effect when applied to target regions.

When the feature toggle is set to true, surges of extremely high frequency, short duration transactions can be mitigated by reducing the likelihood that recently selected target regions are reselected. Enabling this feature toggle increases the average routing cost per transaction, but restores the routing behavior of CICSPlex SM at CICS TS 5.6 before APAR PH30768 is applied. See Changes to CICSPlex SM sysplex optimized workload routing behavior.
com.ibm.cics.db2.origindata={true|false} Service NEW (APAR PH52668): Gives you the option to disable the passing of adapter origin data to Db2® for adapter tracking.

com.ibm.cics.ds.freeussprocesses={true|false} Service NEW (APAR PH56193): Handling of USS processes. Intended for use only under guidance from IBM service personnel.
com.ibm.cics.resourceoverrides.file={name.yaml} REMOVED: Replaced by RESOVERRIDES system initialization parameter. See RESOVERRIDES system initialization parameter.
com.ibm.cics.sm.iep={true|false} NEW: Enables instruction execution protection for certain CICS DSAs. See Instruction execution protection.
com.ibm.cics.tls.minimumkeystrength={1024|2048} Service NEW (APAR PH51719): Sets the minimum key size allowed during TLS handshakes.
com.ibm.cics.web.defaultcipherfile={true|false}
  • NEW: Use defaultciphers.xml as a default set of ciphers for outbound web requests. See Default cipher file for outbound web requests.
  • Service CHANGED (APAR PH60212): Extended to apply to URIMAP resources with no ciphers specified.
com.ibm.cics.web.dnscache={true|false} Service NEW (APAR PH63454): Allows disabling of the URIMAP DNS cache at the region level.
com.ibm.cics.web.hsts.includesubdomains.TCPIPS={true|false} Service NEW (APAR PH55370): Controls whether to extend HTTP strict transport security (HSTS) to sub-domains of the specified TCPIPSERVICE.
com.ibm.cics.web.hsts.max-age.TCPIPS={seconds|-1} Service NEW (APAR PH55370): Sets HSTS for an individual TCPIPSERVICE to override the region wide setting.
com.ibm.cics.web.hsts.includesubdomains={true|false} Service NEW (APAR PH55370): Controls whether to extend HSTS to the sub-domains of the CICS server.
com.ibm.cics.web.hsts.max-age=seconds Service NEW (APAR PH55370): Activates and sets HSTS for a CICS region.

Changes to resource definitions

Table 14. Changes to resource definitions in CICS TS 6.1
Resource 6.1
URIMAP CHANGED: Added support for enabling multiple client URIMAPs that point to the same endpoint (that is, the same host, port and path) in a CICS region.
DFHWSATH, DFHWSATR, DFHWSATX and DFHPIRS program definitions CHANGED: These program definitions are moved from group DFHWSAT to group DFHPIPE. You no longer need to install your own versions of these program definitions because DFHPIPE is part of DFHLIST.
URIMAP definition DFHRSURI CHANGED: URIMAP DFHRSURI now specifies TRANSCTION(CPIW) instead of CPIH. If you are using a customized version of DFHRSURI that no longer specifies TRANSACTION(CPIH), no action is needed and you can continue to use your customized DFHRSURI unchanged. However, if the CSD is being shared with a back level region, see Changes to resource definitions to determine if any action is necessary.

Changes to CICS transactions

Table 15. Changes to CICStransactions in CICS TS 6.1
Transaction 6.1
CDBT CHANGED: The SPURGE attribute has been changed from SPURGE(NO) to SPURGE(YES).
